The North Korean delegation was full of schedule, and this visit was undoubtedly the best opportunity to infiltrate the new Ming culture and promote some arms and commodities.

The first arrangement on the second day was to visit the large bell tower and model houses of Evergrande Real Estate. As for why the first new housing development company was called "Evergrande Real Estate", it was nothing more than the later Evergrande Real Estate, including Evergrande Football and Evergrande Women's Volleyball, so Chongzhen Loves House and Wu, and named it "Evergrande Real Estate". Evergrande Real Estate's big investment was to build a "Evergrande Bell Tower" in Nanjing. The height of this fully reinforced concrete structure is 30 meters high and more than eight floors. It is not so much a building as a tall and thin spire in all directions. The reason why it is called the bell tower is because a large bell designed by Wang Chengen is installed on the top of the front, which is a clock designed once a day.

Therefore, it is famous in Nanjing and has now become a landmark building in Nanjing. Fashionable students have gradually changed the time to the question and answer at what time to what time, and the citizens of Nanjing have gradually become accustomed to the concepts of hours and minutes. This bell tower adopts a fully reinforced concrete structure and a full frame building. The window is equipped with large flat glass, which is transparent inside and outside. The bell tower has only been built and opened for five days, and visitors have been in constant force. However, the North Korean delegation enjoyed special treatment and cleared the venue first. Then Du Jun led the group to visit the bell tower alone. Song Shilie praised the simple appearance and unique building, and the other members were also amazed.

The model houses of Evergrande Real Estate are two-story or three-story buildings. Referring to the design of the second townhouse and four-town villa in later generations, all adopt frame concrete structures, glass windows, bathrooms are flushed with toilets, and tap water is also delivered to the kitchen and bathroom. The model house has been fully decorated, with real spring sofas arranged in the living room, honeycomb coal stoves installed on the kitchen on the first floor, and a row of cabinets are put on. The master bedroom on the second floor is placed with a new large bed and a spring mattress is laid on the bed. The whole home is refreshing at a glance. Carefully considering each detail, the comfort is more than one level stronger than the layout of the old house.

All those who have visited the model room are praised. When some young men saw that the new house was similar to the Royal Club, it can be seen that the advertisement for "Evergrande Real Estate, Royal Style" in Ming Pao is not false. These "prodigal sons" don't care that the house is built outside the city or that the house is more expensive than the house in the center of the city. These rich second generations unambiguously booked a new house for themselves, so that the first phase of the house was sold out in three days. On the one hand, North Korean friends lamented the perfection of the new house, but on the other hand, they were shocked by the price of the new house. However, after the visit, the delegation members unanimously determined that cement and glass should also be introduced to North Korea as soon as possible.

After visiting Evergrande Real Estate, the next highlight is the game - visiting the crossbow-type thunderbolt throwing device. Chongzhen listened to Du Jun's report and learned that North Korean guests were very jealous of pistols, but on the one hand, the production of pistols and rifles was not enough to use themselves, and on the other hand, before fighting with the Qing soldiers, these two killing devices could not be leaked for the time being. Of course, North Korea must support it, and finally decided to support a batch of North Korean crossbow-type thunderbolt throwing device and shotgun. Given that the grenade had been in Dashun last time

The Qing army used it in combat, and then the Qing army also copied the grenades. There is no secret to the grenades. Supporting a group of grenades and crossbow-type thunderbolts built on grenade technology can make North Korea not be beaten by the Qing army's grenades when they are against the Qing army. Of course, it is said to be support, but now the situation in the Ming Dynasty is in line with the saying "the landlords have no surplus grain", so North Korea still has to exchange resources, such as coal and iron ore.

After the converter steelmaking was successfully made, the time of steelmaking and silicon manganese content were controlled, and carbon spring steel was also released. Therefore, today's crossbow-type lightning thrower has been equipped with steel plate springs in the middle of the throwing arm, so the lightning throwing distance has been increased by more than 50%.

Song Shilie and his group watched the Ming Dynasty's thunderbolts performing a single-handed thunderbolt weapon with interest. A thunderbolt soldier relied on a hand-crank mechanism to shake down the throwing arm. After the throwing arm was in place, he pulled out a piece of grenade pin, then put the grenade into the grenade bag, and the handle part passed through the opening of the lightning bag, stuffed the pull ring into the fixing pin of the lightning throwing arm, and then pulled the trigger, a grenade flew out 100 steps away and exploded.

Du Jun introduced: "This is a single-soldier lightning throwing device. The throwing distance is 100 steps, which is equivalent to 130 meters. Oh, this 'meter' is my latest standard unit in the Ming Dynasty. One meter is equal to 3.2 feet. The lightning throwing device uses a ratchet mechanism and can be operated by a single person. The total weight of the lightning throwing device is 55 kilograms, which is equivalent to 32.5 kilograms. Oh, this 'kilogram' is also my latest standard unit in the Ming Dynasty. One kilogram is equal to 11 taels per kilogram. Two people can carry it. When carrying it, it can be carried as a whole or disassembled. After it is disassembled, it can be assembled and put into combat soon."

At this time, the two thunder throwers skillfully performed the disassembly and assembly process. They saw that they were disassembled into two parts, the rack and the throwing arm, and the two parts were instantly replaced. Du Jun continued:

"This individual mine-throwing device can also throw large grenades weighing three kilograms. The throwing distance is reduced to less than 80 meters, but the power of the explosion is greatly increased, which is more powerful than the solid bullet of the Fran cannon, and is much easier to use than the Fran machine. The grenades have insurance pins, and will never explode until they are pulled out, and it is much higher than the Fran machine gun in terms of safety."

As the thunder thrower replaced the grenade with a large grenade, he threw it out with a bang, exploded at 60 steps, and exploded about a pit about one foot, which was indeed extremely powerful.

Song Shilie had only some impression of combat weapons such as cannons, but Jin Yungen was an expert. When he saw that this single-soldier thunderbolt was not inferior to a 200-pound Franchise, he thought that if his Korean army was equipped with such a thunderbolt, he would not know how much more combat power would be improved. No wonder Dashun had a great victory after using the grenade.

Later, when he arrived at the medium-sized lightning throwing device, Du Jun introduced:

"This is a medium-sized lightning thrower. It uses a 6-catties thunder bullet. The throwing distance is 400 meters, which means more than 300 steps. It can also throw a large grenade weighing 3 kilograms. The large grenade can throw more than 600 meters. The total weight of the lightning thrower is 190 kilograms and 320 kilograms. Everyone has seen it. This lightning thrower is equipped with two wheels, and a mule and horse can be pulled."

The Thunder Thrower performed a 6-pound Thunder throwing thunder with a medium-sized Thunder Thrower. The Thunder Thrower used a long rod to pull the mechanism, and then slowly lowered the Thunder Thrower. After falling into place, the other Thunder Thrower pulled out the safety pin on the Thunder Thunder, then made the same arrangement and put it into the Thunder Thrower Bow, and put the pull ring into the Thunder Thrower arm fixed pin. After installing the thunder, the Thunder Thrower was still responsible for pulling the trigger. With a bang, the Thunder Thrower roared the arm, and the Thunder Thunder flew out and exploded at 300 steps. Its power was much stronger than the large grenade.

Finally, the delegation was led to the large-scale thunder throwing device, which was more than one meter high. Du Jun introduced: "This is a large-scale thunder throwing device. It uses 16 kilograms of thunder. The throwing distance is 600 meters, which is more than 450 steps. It can also throw 6 kilograms of thunder. A 6 kilograms of thunder can throw more than 900 meters, which is about 700 steps. This thunder throwing device is usually equipped with three people to operate, and two people can also operate during wartime. The total weight of the thunder throwing device is 570 kilograms and 960 kilograms. This thunder throwing device is equipped with four wheels and requires mules and horses to pull it."

The 16-pound thunder explosion was extraordinary. With a rumbling sound, a big hole was blown up on the ground.

Song Shilie was only shocked by the power of the thunder throwing device, but Jin Yungen has been in the army for a long time and is not unfamiliar with cannons, so he is an expert in identifying goods. These thunder thunders are more powerful than the other explosion, and are simple and labor-saving. Even if the largest thunder throwing device can be operated by two people, it is really a good thing. The key is that this thunder throwing device is fast, which is many times faster than the speed of the cannon firing flowering bullets. When Wanli aided Korea, North Korea also learned the method of launching flowering bullets from the Ming Dynasty. However, this flowering bullet is cumbersome and will explode if you accidentally. Therefore, this flowering bullet is not very popular among the Korean army.

Speaking of which, the flowering bullet transmitted to North Korea from the Ming Dynasty was to install gunpowder into the iron ball bullet body, then open a hole, and insert the detonated fuse. The so-called fuze is a hollow reed tube with a built-in medicine twist. Before loading, cut the corresponding length according to the distance of the target to be shot. When this flowering bullet is fired, the gunpowder is first filled into the cannon chamber, then a circular wooden board is installed to block it, and then fill it with an inch of soil on the wooden board. Adding soil is used to seal gas. It is only because there is a large gap between the cannon chamber and the ball bullet body, so soil must be added. At this time, the ball shell fuze is placed in the muzzle.

The gunbore is not finished yet. The gunbore must be filled with gunpowder through the gap between the ball shell and the barrel, fill the space of the soil layer and the rear half of the bullet body, and then cover the front half of the iron ball shell with a layer of wet soil. This is not finished. A layer of wax must be sealed on it before the cannon can be fired. When firing, first ignite the flowering bullet fuze that extends out of the muzzle, and then immediately ignite the gunpowder on the fire door. The two-stage fired medicine in the front and rear burns, and the shells with wooden boards, soil and wax are fired together. Normally, when the timed fuse is burned, the inner gunpowder of the flowering bullet will explode in the distance.

In the late Ming Dynasty, the method of firing flowering shells using cannons was very dangerous, because even if the seal was used with soil and wax, the flames generated by igniting the launcher inevitably ran from the gap between the shells and the barrels to the front of the shells, which was very easy to ignite the exposed medicine twists, resulting in advance explosions and even explosions. In the Battle of Ulsan in the Wanli period, Ming general Dong Yiyuan was about to take down the Japanese Warring States strange man, nicknamed "Ghost Stone Manzi", Shimazu Yoshihiro, who was nicknamed "Ghost Stone Manzi", was the result that the cannon exploded when firing flowering shells, causing consecutive explosions of the ammunition depots, resulting in the defeat of 30,000 Ming troops, which led to the loss of Sizhou again. Since then, both the Ming and Korean troops have been frightened when firing flowering shells, and are afraid of explosions. Therefore, even if it is absolutely necessary, the army rarely fires flowering shells.

With Jin Yungen's years of experience in the Korean army, he immediately fell in love with this fool-style thunderbolt. It also fires flowering bullets. Compared with cannons, the only disadvantage of the thunderbolt thrower is that its range is slightly inferior, but it is quite good to throw 6 kilograms of thunderbolt thunder for 700 steps. When the cannon fires a flowering bullet, the thunderbolt can shoot more than 10 thunderbolt bullets. Moreover, the thunderbolt does not need to be ignited, and there is no need to blow up the barrel. Moreover, the thunderbolt is easy to carry and drag to the battlefield.

It can be fired. Compared with the difficult transportation of bulky cannons, it is difficult to install cannons in place. These shortcomings are not much stronger. Moreover, both Thunder and grenades have insurance. The insurance pin is pulled out when firing. When Thunder is thrown away from the throwing arm, it relies on friction to ignite Thunder. It can be fired regardless of sunshine. What is more satisfying is that Thunder has a variety of delayed explosion times, and different Thunders can be selected according to the throwing distance. Obviously, Thunderstorms are stronger than the cannon launching flowering bullets, which can be said to be stronger than the cannon launching flowering bullets.

Jin Yungen muttered to Song Shilie for a long time, which made Lord Song unable to care much. He asked Du Jun at that time: "Mr. Du, we were very worried when we saw the power of the thunder throwing device. I wonder if we could ask the Ming Dynasty to send craftsmen to teach me that North Korea can also make such thunder throwing devices? So that North Korea can use this to repel the Qing army and help the Ming Dynasty restore Liaodong." Song Shilie saw that this thing was not difficult, and probably as long as someone gave some advice, it would be not difficult to make with the ability of North Korean craftsmen.

When Du Jun saw that Song Shilie had indeed fallen in love with the thunder throwing device, he immediately followed the flow and said:

"I am not able to make up this matter. I will be able to decide this matter until Lord Song meets Wang Chengen tomorrow. It will be possible for Eunuch Wang to decide. It is because the emperor has newly promulgated the Patent Law. Any new technology of our Ming Dynasty, as long as the inventor has registered a patent, will be protected by the patent. This lightning thrower is a patent registered by the Royal Military Engineering Academy. The Royal Military Engineering Academy is now presided over by Eunuch Wang. If you want to imitate the lightning thrower, you must obtain the consent of the patent inventor. You must sign a patent license agreement and pay the patent license fee to imitate it. In addition, some materials problems may not be solved by you. For example, the steel plate spring, I have just successfully tried the Ming Dynasty. This is the patent of the Royal Institute, so you have to talk to Eunuch Wang in person."

Speaking of this, Du Jun felt that he was just a patent and a patent fee, and forgot the word "morality" beyond the sky. He was so fucking subtle. When did he become so stinky? He added:

"Mr. Song doesn't have to worry. My Ming Dynasty has always been very generous in supporting North Korea and has no embarrassment. I will bring you here to visit, and it is obvious that the emperor intends to support North Korea. I guessed in private that Lord Song came to Nanjing this time because the two princes of your country were still in Shenyang as the protons of the Tartars, so the emperor may also consider secretly reaching a joint relationship between the two sides on the grounds of business exchanges, so as not to be heard by the Qing court and endanger the protons."

After hearing this, Song Shilie was the teacher of Li Jing, the great king of Fenglin, one of the protons, and felt ache when he heard this. He could not make a public pilgrimage this time, so he could only come to the Ming Dynasty secretly. It was because of this difficulty that he hated the Tartars even more. Therefore, he saw that since the Ming Dynasty established its capital in Nanjing, there were signs of prosperity, and all kinds of new firearms were shocked one by one. Therefore, he had greater hope in his heart. This time, he must obtain the support of Chongzhen, and he can also enrich the country and strengthen the army like the Ming Dynasty. Taking advantage of the Ming Dynasty's north to settle Liaodong, he also got rid of the Qing Dynasty in one fell swoop. However, it was really troublesome to think about how his students could escape safely at the hands of the Tartars.
