In Li Chengqian's opinion, the test of the earthen cannon was a failure, and if it weren't for Li Er's insistence on seeing what this thing was, he would definitely not have carried out this kind of test before the research was successful.

But there is no way now, the old man refuses to give money without looking at the power of the earthen cannon, and if he doesn't give money, the research in the future will not be able to continue, so the helpless Li Chengqian can only take the errand head-on.

Li Er took the lead and led everyone down from the stands, and the first thing was naturally to look at those earthen cannons.

But that thing is black, and it takes up a lot of space there, and if you don't fire a cannon just to look at it, it's really nothing to look at, and it's just an iron pipe with a special shape.

"This is the 'cannon'?" Cheng Fairy, Li Jing, Fang, Du and the others circled around the three earthen cannons a few times, and then patted the body of the still warm cannon and asked.

"Yes, this is a cannon, but there is nothing to see about this, so uncles might as well go to the front test site to have a look." Li Er had already seen these earthen cannons, and it didn't matter if he looked at them now, Li Chengqian also knew what Li Er wanted to see, so naturally he would not continue to waste time here at the gun position.

"Cheng, go to the front and have a look." Li Er was very satisfied with Li Chengqian's suggestion, damn the weather was too cold, it was better to finish reading it early and go back early.

In this way, Li Er took the lead, accompanied by Li Chengqian, Li Jing, Du Ruhui and others, and everyone got on their horses and ran towards the 'enemy position' 500 paces away.

The destination, after everyone took a closer look, everyone was stunned, except for Li Chengqian.

"This, this is a broken man!"

"Your Majesty, it's difficult, is this the result of the 'cannon' just now?"

"Good, good, good. Your Majesty, why do you have to come to my right guard with a hundred 'cannons'! ”

The test ground was placed by two hundred scarecrows in a mixed formation of infantry and cavalry, and the straw men were covered with the strongest plate armor in Datang now, no matter which way you look at it, this is a standard Datang military formation. But this was only before the test, and it was completely different from what everyone sees now.

At this time, what Li Er and the others saw was a mess, straw flying everywhere, and the solid plate armor was like rags that had been ravaged by a powerful big hand, twisting and scattering everywhere.

"Prince, is this what you said about the 'cannon' that has not yet succeeded?" After a while, Li Er raised his hand to stop everyone's comments, and asked with his eyebrows twisted.

"That's right." Li Chengqian replied confidently.

As a result, Cheng Fairy's gong-like voice came over to the side: "This is not successful? Boy, what else do you want? ”

"Don't you think that's too close? It's only 500 steps, what can you top, you can hit a bed crossbow, you can hit a trebuchet, so what do you want this thing for? Li Chengqian was a little unimpressed by Lao Cheng's statement.

Later generations are accustomed to hearing that it can shoot dozens of kilometers of artillery, hundreds of kilometers of missiles, this kind of cannon that can shoot 500 steps is a small toy in his opinion, it is almost the same as a salute, used to siege the city ......, or don't joke.

However, the speaker has no intention of listening, and Li Chengqian doesn't care about the five hundred steps, which doesn't mean that the veteran ruffians like Li Jing and Cheng Fairy don't care.

So without waiting for Li Er to say anything, Li Jing said: "Five hundred steps is not close, and I am afraid that I will not be able to see it if I am far away, looking at the power of this 'cannon', if it is used to hit the city gate, it should be able to be solved at one time." ”

"Like, 500 steps is not enough? In addition to Datang, is there any country around here that can have something to shoot five hundred steps, don't be too ambitious. Duan Zhixuan also interjected on the side.

Li Chengqian has nothing to say about these ignorant and interesting turtles, and the cannons that can only shoot 500 paces are so satisfied, I really don't know how they would react if they knew that the cannon could shoot more than 100 miles.

However, Li Chengqian was depressed, and Li Er was also depressed, feeling as if his money had been spent in vain.

I knew that this thing could hit 500 steps away, and I studied a fart, so I just used it directly, so why bother to give that stinky boy another 30,000 yuan and let him continue to mess around.

In fact, Li Er and Li Chengqian have made a mistake in this matter, that is, standards.

In his opinion, as long as the cannon is called, it must at least be able to hit a target within 15 miles, and after all, the gun can hit 400 meters in World War II, and the distance of 500 steps is really close in his opinion.

However, the standard in Li Er's heart is one hundred and fifty steps, because a bow that can shoot one hundred and fifty steps in the Tang Dynasty can basically be regarded as a strong bow, and the Tang army basically attacks at about one hundred and fifty steps.

In such a situation, 500 steps is actually a long way away, and if nothing special happens, basically 500 steps belongs to the kind of distance that can only be hit by me, and you can't hit me.

This is the same as the difference in understanding of clarity between people who are used to 4K film sources and people who are used to seeing 320P film sources.

Therefore, the fundamental reason for this misunderstanding is what Li Chengqian said to Li Er: The distance is very close and cannot meet the requirements of the war.

This made Li Er think that the 'cannon' thing could only hit within a hundred steps, and if this was the case, it would really be useless to Datang, so he agreed to let him continue to study.

Now that the results of the experiment are out, Li Er will naturally think that his own bastard wants to cheat him out of his money.

Du Ruhui was honest in the end, looking at the dissatisfaction on Li Er's face, the innocence on Li Chengqian's face, and the excitement on the faces of the soldiers, he asked at the right time: "Your Royal Highness the Prince, if five hundred steps are still close, how much distance do you think is appropriate?" ”

"Since it's a cannon, how can it be able to exert its full power at a distance of about ten miles, five hundred steps...... How can this thing be called a 'cannon'. Li Chengqian kicked the smashed and deformed plate armor on the ground, and said a little depressed.

"Fart, Ten Miles! Why don't you say a hundred miles. Li Er, who couldn't bear it, finally broke out, he felt that he had been deceived by Li Chengqian, but now this bastard boy actually said that he wanted to get a weapon that could hit ten miles away.

Is there such? That's ten miles, how can you fight if you can't see it? Even if you can really hit it, if you can't see the target, can you try it a little bit?

Li Chengqian didn't seem to hear the irony in the old man's words, and said with a tangled face: "Father, a hundred miles can be done, but there are more things that are needed, not only the problem of barrel materials, but also the shells and gunpowder must be transformed, hmm...... There are also ways to change the way of communication, so there are too many things to change. ”
