In the middle of the night, Shi Tou stood at the top of Kaiping City, looking at the darkness in the distance, with a lazy look.

The garrison was at the border for several days, and Shitou was sent to Ye Wu to take him away. With the cooperation of Ye Wu to take him into the horse bandits, he had already found out the location of the bandits. As soon as the delegation returned to Beijing, he took action to snatch the things back.

But the mission has never come back, and it is hard to deal with Shi Tou. He can only wait day and night. The mission, you should come back.

Hala and Lin

Yang Shan stood in front of Yesian's palace, with a decadent look on his face and haggard.

It was already the tenth day, so I refused to see them first.

In negotiations, some talks can only lead to results, and some talks can only lead to concessions, but now there is no need to discuss.

No one can see it, so what birds can talk about?

Ren Li came from behind and supported Lao Yangshan:

"Sir, let's go back. Yexian will definitely not talk to us."

Yang Shan turned his head, and a ray of light emitted from his turbid eyes:

"What is Mr. Ren talking about?"

Ren Li looked difficult:

"My people have already found out. When we arrived that day, Duke Zhong had already set up his troops on the border."

Yang Shan was a little puzzled:

"What's the problem with Chen Bing's border? Even if he doesn't want to talk about Sucheng, there is no problem with using troops to protect the security of the mission."

Ren Li smiled helplessly:

"My elder brother!"

"It would be fine if it was someone else!"

"The one who is on the border with the army now is Duke Zhongguo! The first general of the Ming Dynasty, the famous general who defeated Yesian twice in the Central Plains. Every time he fought Yesian and threw away his armor. Only by relying on the pawn of the Supreme Emperor can he save his life."

Yang Shan's body was shocked:

"Are you afraid first?"

Yang Shan had a little puzzled look on his face. Yexian was the head of the Mongolian Grand Master and the leader of the Ola tribe, the largest tribe in the grassland, was actually afraid of Sucheng. This is too abnormal. Isn’t it all said that heroes are brave and fearless and fearless?

Ren Li nodded:

"Ye Xian is afraid. I think Ye Xian's behavior for the past few days has not put back the Supreme Emperor's mind."

After hearing this, Yang Shan could only walk back with Ren Li:

"But all this is your speculation. If we go back to the court like this, I can imagine how the Censor Kedao will attack us. If we go back like this, we will probably die without a place to bury."

Ren Li shook her head:

"Your Majesty is kind and ruthless. Although he is harsh, he will definitely not make you and me too miserable. After all, the lord is also an important official of the court."

Yang Shan staggered and almost fell down. He patted Ren Li on his arm:

"I will take all the responsibilities together when I return to the court. If Mr. Wang is willing, I hope to take some care of my descendants of the Yang family in the future."

Ren Li was a little confused. What could it be if the negotiation failed? The several groups of missions that came before also failed, and he didn't see His Majesty dealing with them.

Yang Shan shook his head and ordered Ren Li to say:

"Then we will set off on a date and return to Beijing to report our mission. We have failed."

...

When Sucheng received the message from the mission again, it was already the 14th day after the mission set out to return to Beijing. The night sent by Shitou did not take over the stars and nights, but it was only a day earlier than the mission.

Su Cheng, who had just walked to the door of the firearm, smiled and ordered the messenger to say:

"After sending the order, Deputy General Zhang ordered him to set off immediately, eliminate the horse bandits who robbed the delegation, and must recover all the prohibited items needed by the royal family and hand them over to the court."

The messenger took the order.

When Su Cheng entered the firearm, he saw a group of craftsmen gathering together, holding a three-eyed gun and studying.

When he saw Su Cheng coming in, a group of craftsmen scattered as birds and beasts.

Only Lao Luo and Su He did not move.

When he saw Su Cheng, Su He said helplessly:

"Brother, it's not easy to build a musket with reloaded gunpowder in the breeze. We opened the fire door on it. What do you think of this?"

Su He showed Su Cheng the three-eyed gun in his hand.

Above the buttocks of the round musket, an arc-shaped air was opened, with a cover on the air, and then there was a cover fire door on the left and right barrels.

Su Cheng played for a while and reminded the two of them:

"This weight is a bit too much. It can be made into a single-eyed musket. There is no need to be all three-eyed muskets."

Lao Luo said beside him:

"That would be less powerful. If a three-eyed gun shot, it would be able to kill and injure two or three people. If it was changed to a single eye, it would be great if it could hurt one person."

Su He thoughtful, looked at the musket in Su Cheng's hand and frowned.

Su Cheng returned the three-eyed gun to Lao Luo:

"You don't have to consider the power, you can hurt one person, but you can load quickly, and then fire one gun in the past, and change it to be able to fire three guns or even more. Wouldn't this be resolved."

Lao Luo shook his head:

"The master is inappropriate in this regard. The ancestor tried his best to make a powerful three-eyed gun, which means that the power of a single-eyed gun must not be as powerful as a three-eyed gun."

"If it is powerful and loading is fast, the gun will definitely explode easily. It turns out that the gun will explode after six times of power. If it is powerful, it will explode after four times."

Su Cheng had to think that Lao Luo was right. If the iron material could not be improved, the more powerful the gunpowder was, the faster the fire would be.

Su He spoke from the side:

"We can improve the quality of iron. I have long felt that the method of smelting iron is not right. There are too many debris in the iron liquid, and the iron is not pure enough, so the strength is insufficient, and there are too many places to improve."

Su Cheng nodded:

"Lao Luo, come and build a single-eyed musket. Just follow this style and make a uniform mouth size. Use oil paper to wrap some gunpowder and put it in directly with oil paper wrap."

"Su He, come with me, let's study how to smel iron so that we can make a barrel that is not easy to explode."

Su He was very happy. He was willing to do this. He was actually not interested in muskets. He was barely able to make gunpowder. His favorite thing was to burn things, just like burning glass.

Su Cheng and Su He found a craftsman who was familiar with iron craftsmanship and told him about the requirements for iron craftsmanship. The craftsman immediately listed the various utensils he needed. Su Cheng sent Su He to find Yang Xin to get silver and money, either buy or build, and get them out as soon as possible.

When he returned to the General's Mansion, Bai Yan came to see Su Cheng, and his expression was hesitant.

Su Cheng lay down on the recliner and asked casually:

"What's the matter, white salt?"

As he said that, Su Cheng closed his eyes. If he wanted to build a good musket, he had to refine good iron first. However, looking at the craftsmen of Xuanfu, it is unlikely that they could refine good iron.

It's still up to yourself.

I remember that I used to smelify iron in the blast furnace, and blow the air in and burn the impurities. The real process has to be explored through simulation. If you have headaches and dizziness, put it aside first.

The black smoke winds, and the scene changes.

Sucheng entered the simulation.

On the tenth day, the blast furnace built was made, bellows, chopping boards, and various utensils.

Su Cheng led everyone to start smelting iron.

Put the pig iron in and burn the charcoal.

Su Cheng directed a group of craftsmen to start burning the fire. After a day, the smoke in the blast furnace became thicker and thicker, but no iron was flowing out.

"Bang"

After a loud bang.
