With the fierce artillery fire, the Goguryeo defenders in the cities also raised white flags and surrendered. Yuan Gassuwen had already withdrawn with his main force, and the remaining troops in Goguryeo were only about one thousand people. This was also what Yuan Gassuwen abandoned before in order to extend the time of the city as much as possible. However, those defenders were already shocked by the thunder cannon that shocked the world and the earth, because they thought they could not stop this kind of cannon. Once such cannons were bombed, the city walls would be collapsed. Didn’t they see that the bluestone city walls were collapsed? How could their flesh and blood be able to withstand? So they chose to surrender. The Tang Dynasty took the first important town since the conquest of Goguryeo, and it was the important town where Emperor Yang of Sui suffered heavy losses.

"We took Liaodong without losing one soldier. Emperor Yang of Sui could not take it down by one million. Now we conquered without spending one soldier. What a blessing!" Li Shimin also sighed quickly.

"This shows that the emperor is wise, the generals are in charge of command, and Lord Jing Wen has invented this flying thunder cannon, which has achieved such great results!" A middle-level civil servant immediately flattered.

"Haha!" Li Shimin smiled.

Li Shimin is very vain now, because even the millions of Emperor Yang of Sui had no city that could be conquered by Emperor Yang of the Sui, and now he conquered without a single soldier. This obviously shows that Li Shimin is much stronger than Emperor Yang of Sui, so Li Shimin is of course happy. So Li Shimin is inevitably proud now. After all, no one wants to surpass the emperor of the previous dynasty, so that it can be said that it is reasonable and legal to replace the previous dynasty. Whether it is in terms of the so-called will or ability, it is in line with the "public opinion". Therefore, if the two emperors do the same thing, the result is such a big difference, and this is a matter of ability.

If Jing Wen knew Li Shimin's idea, he would definitely think of it. If there were no artillery invented by Jing Wen, Li Shimin would not know how many lives it would take to cover the Liaodong City. This Liaodong City was simply a super turtle shell and a hedgehog. With the original strength of the Tang Dynasty, it would have to collapse several teeth even if it was conquered. But now the attack is so smooth, it is not because Jing Wen invented the flying thunder cannon, which turned the strong city of Liaodong City into a tofu, so everything is the butterfly effect brought by Jing Wen!

The leader of the Xi tribe next to him looked like a bitter face because they lost thousands of soldiers. The so-called Tang Dynasty conquered Liaodong without spending one soldier. This was only founded when the Xi tribe and the Mohe tribe lost thousands of people. Of course, the Tang Dynasty did not lose one soldier. As for the soldiers of the Xi tribe and the Mohe tribe, they were all forgotten by Li Shimin and those generals. So it was obvious that they did not take the Xi tribe and the Mohe tribe seriously at all, but regarded them as cannon fodder and as consumables.

However, the leader of the Xi clan was also cursing that since the Tang Dynasty had such cannons long ago, why did they still want to attack the city? The leader of the Xi clan didn't know at all. Jing Wen and Li Shimin actually wanted to consume their strength, and then they would be much easier when they turned against each other in the future. As for them, they would probably not get any benefits at that time, and instead they would lose their wife and their troops.

"Your Majesty. We have found many warehouses in Liaodong City, with many rolling stones and woods. And we have found no less than 10 million arrows. And we have found many giant crossbows under the city walls that are called ten thousand arrows piercing the hearts of the Goguryeo people. These giant crossbows can fire hundreds of arrows at a time, and can kill dozens to hundreds of people at a time. So it is very powerful. There are more than twenty such powerful crossbows, including four city walls in the southeast, west and north. "The soldier said.

When Li Shimin heard of this giant crossbow, he immediately became interested. After all, this is very powerful. He can shoot hundreds of arrows at a time and then kill dozens of people. This can be said to be a very powerful weapon. If it is used to defend the city, it may really cause heavy losses to the Tang Dynasty. However, this giant crossbow must be covered. If it is not covered, it will be easily hit by the enemy's catapult cart or other weapons, which is useless. Now the Goguryeo people have brought these things into the city wall, so that they can kill and kill people close.

"The magical axe is a magical skill!" "The magical axe is a magical skill!"

Those engineering staff were very shocked by the ability of this giant crossbow, because the pulling force of this giant crossbow is very huge, and it must be pulled together with several horses to be able to be turned. The firing rate is not fast, it takes about one minute to be once, and the consumption is not small. After all, the cost of making arrows is much higher than that of the small lead bullets of guns and cannons, and the cost of using this giant crossbow is not low. Jing Wen also happened to know an allusion in Western history. The strength of the gun at the beginning was not as strong as that of the crossbow, but because the production cost of the guns was lower than that of the bow and arrow, the gun was preserved. Therefore, this crossbow is much higher than the cannon invented by Jing Wen, and such a large giant crossbow may not be lower than that of Jing Wen's cannon, which is mainly a problem of manual production.

"Jing Wen, this should not be as powerful as the cannon you invented, right?" Li Shimin asked.

Jing Wen immediately said: "If we want to talk about the current power, it should be comparable. However, the fire rate of cannons is several times faster than theirs, and the cost of firing crossbow arrows is much higher than that of our lead shells. Moreover, our cannons can use a variety of shells, so overall, the cannon is better!"

Li Shimin nodded and said, "If you hadn't invented this cannon, then we would really have to use the lives of soldiers to fill it. At that time, we have concentrated the whole country's strength and may not have been able to conquer this Liaodong city. It can be said that all this is based on your contribution to Jing Wen. Therefore, this conquest of Goguryeo is your well-deserved first."

"The emperor praised it!" Jing Wen quickly said modestly.

The civil and military officials were envious. After all, Jing Wen raised military funds, which was the first merit. However, that first merit refers to the first merit, not the greatest merit. Now with cannons, Jing Wen is also the first merit, but this is the greatest merit.
