Liu Hongji really had nothing to say, after listening to Li Ji's words, he also felt that it was useless to keep the city wall, if he really encountered an army with such a long-range attack strength, the city wall was powerless to stop the enemy except for restricting his own people from escaping.

Of course, he also thought about it, it's a big deal that when you come to beat me, all my people will hide under the city wall, so won't it be fine? Just like when dealing with trebuchets in the old days.

But after thinking about it again, he felt that it was wrong, because the largest city in the Tang Dynasty was Chang'an City, but how big was Chang'an City? It is more than 9,000 steps long and more than 8,000 steps wide, so can't the cannon hit this side and the other side? It's okay to drag the cannon under the wall and hit the wall on the other side, right?

Thinking of this, Liu Hongji didn't say anything anymore, shook his head with a wry smile and said to Li Ji: "Is there anything more ruthless?" Let's talk about it. ”

"Guns, we have a new batch of guns here, with a range of 400 paces, what do you think? And the rate of fire is very fast, so you don't have to stuff gunpowder and then iron sand like before. Li Ji said with a strange smile.

"A gun with a range of 400 paces? This thing ......" Liu Hongji no longer knows what to say.

As far as he knew, the longest-range bow could shoot four hundred paces away, but it had to be special, and a normal bow could be considered powerful if it could shoot two hundred paces, and even a crossbow wouldn't have such a great power.

Datang is gradually becoming stronger, but also gradually moving towards the unknown.

Liu Hongji suddenly found that he didn't seem to have come to know his country well.

In the past few years, the changes in Datang can be described as changing with each passing day, those huge machines have made the work that used to require many people to work for a long time simpler, just a few times the operating lever, everything has been completed.

The power of man has been defeated again and again in front of the machine, and these are the only cases that have appeared in recent years, but they are enough to change the three views of people.

……

At the same time, His Majesty the Great Tang Emperor was also surprised.

"The 6,000-step cannon has also been studied?" Looking at his calm son in front of him, Li Er only felt a toothache.

What cannon can hit 6,000 steps? Or can it hit a target 6,000 steps away, so is it still called a cannon?

"Father, six thousand steps is the limit, if there is no major improvement in materials, basically there will be no more advanced Zhenguan cannon within ten years." Li Chengqian's expression was as flat as he said, as if he was talking about what he ate for dinner yesterday.

But Li Er couldn't accept such a reality, looking at Li Chengqian's calm appearance, the more the old man thought about it, the more angry he became, and finally he couldn't help but scold: "Six thousand steps is not enough, what else are you going to do?!" ”

"Father, if there is enough technical support, we can fight from Xi'an to the Wa Kingdom in one shot." The old god Li Chengqian was talking, but he was thinking about the 'big killers' that could fly half the world in the future.

I didn't want the old man to hesitate, so he was silent for a long time before he said categorically: "No, six thousand is enough, don't do this thing in the future." ”

"Why?" Li Chengqian asked with some puzzlement.

"No, six thousand is the limit, so you don't have to study it any further." Li Er glared at his son, and then said: "In the future, this number will be used as the standard, as long as the range of any weapon exceeds six thousand, it will be overdue." ”

What? Li Chengqian's eyes stared at the boss.

There's no need for that, is it? To get a cannon with a range of more than 6,000 steps is overreach? Is there a need to be so strict? When did the old man also start to learn from the Braided Dynasty?

Thinking of this, Li Chengqian hurriedly explained: "No, father, you can't do this, in the future, the power of this weapon will become greater and higher, and the range will be higher and higher, and six thousand steps will not solve the problem at all." ”

Hearing Li Chengqian's explanation, Lao Li was also angry, slapped the table and shouted: "You solve a fart, Lao Tzu asks you, who are you going to hit with so many weapons?" Now, apart from our family, who else can have a maximum attack range of more than 500 steps! ”

"Uh......" Li Chengqian was stunned by the old man's yell.

In fact, he himself doesn't know who he's going to fight if he is given a DF now, because it's completely unnecessary.

In the era of the Tang Dynasty, it seems that 500 steps is already the limit, and making a cannon with a range of 3,000 steps is already bullying people, and 6,000 is equivalent to beating a child, if the range is higher.......

Well, no matter how high the range is, even the accuracy cannot be guaranteed, and communication cannot be contacted.

After all, the shells need to be corrected, and in later generations, there are walkie-talkies, and satellites can be directly contacted, but in the era of Datang, where communication is completely dependent on roaring, no matter how far the range is, it is nonsense.

Thinking of this, Li Mu didn't bother anymore, six thousand is six thousand, the old man is afraid of being shelled in the middle of the night, and our family is also afraid, Daming Palace is not much in total, and a cannon with a range of six thousand meters may penetrate the palace if it is placed two miles away, for the sake of safety, forget it.

……

But forget it, you still have to do what you need to do, such as the mortar, with smokeless gunpowder, that thing can be studied.

Anyway, the principle is very simple, it is a large bullet, using the principle of free fall to hit its primer, and then fire something, and then match it with an alloy barrel, which is even simpler than that bazooka.

After listening to Li Chengqian's explanation, Tang Shanzhi didn't take much time to make the prototype of the cannonball, that is, a large bullet, and it took two days to arrange for someone to make an alloy steel barrel, and everything was completed.

Li Chengqian didn't think that things would be so simple, so when he saw Xiao Tang ordering someone to take out the so-called cannonball, the whole person was stupid, and he looked at the round thing blankly and asked, "I said Tang Shanzhi, what are you doing?" ”

"Cannonballs, as you say, large bullets." Xiao Tang said confidently.

"This is a cannonball? I look at what an eggplant looks like! Cheng Chumo, who had returned to Chang'an and had already finished his marriage, took the round cannonball, put it in his hand, and said sullenly.

Although this guy has been married, he still looks reliable, he has not grown at all, looking at the way the cannonball is flying up and down in his hand, Li Chengqian's frightened heart almost didn't jump out.

You know, although that thing looks like an eggplant, it is not a real eggplant, and if it falls to the ground, a bad one may send everyone present to the western sky.

Tang Shanzhi was obviously also frightened by Cheng Chu, but he didn't dare to shout out, for fear of being distracted and accidentally dropping the 'eggplant' to the ground.
