Jingwen and the emperor came to a cannon that looked very thick, and Li Shimin looked at this "pipe" and didn't know what this thing was for. He immediately touched the tube, which frightened Yuan Hua.

"Your Majesty, this danger, please go to the back!" Yuan Hua said.

"Is this dangerous?" Li Shimin asked.

Yuan Hua immediately said: "Your Majesty, once this explodes, the explosive power is even greater than that of the take-off bomb." If you're so close, that's ......."

Li Shimin didn't say a word, and immediately hid away. This is not that Li Shimin is afraid of death, but his position, and he is forced to "fear death". Because he is the emperor, if something goes wrong with him, then I am afraid that the country will be in chaos, so even if the leader of the country is not afraid of death, you must also be "afraid of death" because of the form. As for what kind of national leader personally charges to the front line, this is still okay, but if it is real, then you are not afraid of the dead in time. Because what you are carrying is not your own net worth and life, but the future of the country, so if you joke with your own life, it does not represent yourself, but the future of the whole country. Therefore, Li Shimin immediately avoided it, because the things he was carrying were not ordinary.

"Your Majesty, do you see that city wall in the distance? This is what I built a long time ago to test all kinds of firearms. Jingwen asked, pointing to the city wall in the distance.

Li Shimin estimated it and said: "This is the city wall of a county town, which is about equal to the strength of the guards of a county town. ”

"Your Majesty, wait a minute, you can watch a good show!" Jingwen said.

Jingwen asked the ministers to plug their ears, but everyone obviously didn't care, they obviously didn't know what this firearm meant.

"Your Majesty, since you don't want to plug your ears, then don't blame me later!" Jingwen said.

"I've been through a lot of winds and waves, what can a small missile do to me?" Li Shimin said.

Jingwen immediately made a gesture to Yuan Hua. And Yuan Hua immediately asked those who were in charge of testing the artillery to start preparing. And these personnel have been recruited since the first year of Zhenguan, and now they have a few years of work experience, so they can test gunpowder. These are all experts in playing with gunpowder, and after several years of training, they are more proficient than Jingwen, and they are more familiar with gunpowder.

"Three! Two! One! Ignition! Yuan Hua shouted.

"Smack!" "Smack!" "Smack!"

Three shells were fired and then quickly landed on the distant city wall.

"Boom!" A puff of smoke blew up, and the walls of the city became a puff of smoke.

And Li Shimin and the generals also exclaimed, because the walls of a county town were blown up like this.

"Your Majesty. Emperor? Jingwen immediately asked.

"What do you say? I can't hear you! Li Shimin immediately said in a loud voice.

Because they can't hear with their ears, these people talk very loudly.

"What did you say, son-in-law? Why is this thing so powerful? Cheng Yanjin said.

Jingwen didn't answer because their ears couldn't hear for a while, so Jingwen had to wait until their ears heard clearly.

After about an hour, everyone's ears finally heard.

"Jingwen, what the hell is this? So powerful? Li Shimin asked.

Li Shimin looked at the city wall that had completely collapsed in the distance, and said in horror. At that time, although the missile had also broken the wall of Dingxiang City, no one could see this situation with their own eyes. And these veterans still saw with their own eyes that a city wall was broken down like this. The shock can be described as quite staggering. At that time, the missile only blew a gap in the city wall, but now it is actually blowing up the city wall, and the power is simply incomparable. It's terrifying. Many people want to face this kind of power with their own flesh and blood, can they resist it? Fear. In the face of such a powerful force, the flesh and blood can only die.

Jingwen immediately replied: "This is called a flying thunder cannon, which is a kind of cannon. ”

Next, Jingwen introduced what a flying thunder cannon is. In fact, Jingwen is a flying thunder cannon. That is, it is a weapon that imitates the army of later generations during the founding war. This weapon is very powerful, and it is not a big problem to bomb some city walls. However, although the range is a little shorter, this team is nothing in ancient times. The range of the Flying Thunder Cannon is only 500 meters. But what weapons could the ancients have that could cover up to 500 meters away? That is, Jingwen's missile. The enemy of his ancient Chinese people simply did not have any weapons capable of covering up to five hundred meters away, even if it was a catapult. Don't look at this flying thunder cannon It looks simple, but Yuan Hua has also studied it for several years. The structure of the Flying Thunder Cannon is not complicated, but there is not much steel that can withstand the Flying Thunder Cannon. In order to study this flying thunder cannon, Yuan Hua should have raised the level of steel smelting a lot. In ancient times, the zuò cannon was mainly limited by the ability to smelt steel. As long as the steel problem is solved, there will be no problem with that qiē problem.

"Oh my God! If there is this thing, what city in the world cannot be breached? Even Chang'an ......," Cheng Yanjin said inevitably.

Cheng bit King Kong wanted to say something, but he suddenly remembered that he was using Chang'an as a metaphor, which was very disrespectful. However, what Cheng Yanjin said was also true, because three shells completely destroyed the city wall that was more than 20 meters long. Although the walls of Chang'an City are thicker and longer, it is a big deal to blow them up a few more times. Therefore, Chang'an City may not be able to survive under the attack of this kind of firearm, so Cheng Yanjin is inevitably amazed.

And Li Shimin couldn't help but feel very heavy, because Chang'an City took many years of construction before it became a fortified city that was claimed to be impenetrable. But as soon as Li Shimin built Chang'an City, he was immediately slapped by this artillery. Although the walls of Chang'an City are very thick and big, people will not just shoot a few shots at a time! In case the family mobilizes hundreds of these artillery pieces to attack at one time, and bombards them day and night, Chang'an City will definitely be breached. Thinking of this, Li Shimin was frightened.

"Your Majesty, how is this god of war?" Jingwen asked.

"The god of war is indeed the god of war! In the future, it will probably be impossible for brave generals who rely on personal bravery to survive on the battlefield. Li Shimin said with a wry smile.

The generals on the scene were silent for a while, because with this kind of firearm, there was no market for the generals who relied on their personal bravery. Cheng Biting Jin, Qin Qiong, and even many more, I'm afraid it won't be long before I retire. This feeling of uselessness for heroes made them feel sad in their hearts. Although a new army was formed, it still did not depart from the combat method of cold weapons. But now that there is this kind of artillery, it can be said that personal bravery is completely useless. In the future, these brave generals will naturally disappear. Now, they are just relying on the qualifications of the founding heroes, and I am afraid that there will be no part for these brave generals to speak on the battlefield in the future.
