With Qi Yu's shouts, other craftsmen also cheered, which made Zhao Yan overjoyed and strode to the cannon. He bent down and checked the cannon with Qi Yu, but found that there was no damage to the comb and the mother tube, and the shells were shot out, but there was nowhere to be seen here.

"It's great, check the landing point of the shells quickly and calculate the range and accuracy!" Zhao Yan also ordered excitedly that artillery cannot just shoot the shells out, and range and accuracy are also very important indicators.

When Qi Yu and others heard this, they immediately agreed, and then ran quickly to find the landing point of the shell. As a result, after a while, they saw a craftsman shouting in front of them. It seemed that he had found the landing point of the shell. Zhao Yan roughly estimated that the shell was about one mile away and the range was a bit close. This may be because there was a problem of air leakage between the tube and the mother tube. The direction of the shooting was roughly the same as the direction they aimed at, which means there should be no big problem in terms of accuracy.

"Yan'er, has the test shot been successful?" Zhao Shu walked up to ask again, and at the same time he showed a puzzled expression on his face. He had known before that the power of this kind of cannon was not very powerful, but he thought that no matter how small the power was, it should not be worse than the crossbow. But just now he only heard an explosion, and no change was found.

"Father Qi Bing, this test fire was considered successful, but there were some small problems in the middle, which made the range of the artillery a little close, but the accuracy should be quite good!" Zhao Yan said the truth at the moment. He had made up his mind that no matter how disappointed Zhao Shu was, the development of the artillery would continue.

Just as Zhao Yan finished speaking, the craftsman who had just discovered the shell had run back, and then reported to Zhao Yan loudly: "Qi Bing, the range of the son and mother cannon this time is about 1.3 miles, and the direction deviation is extremely small. You can conduct a second test shot."

"Very good, then prepare for the second test shot and prepare the target!" Zhao Yan also immediately ordered, but Zhao Shu and others were all confused. When they observed the demonstration of new weapons in the past, they just had to look at the power of the new weapons directly, and they had never been as complicated as they are now.

Zhao Yan also saw the confusion on Zhao Shu and others' faces, and immediately explained: "Father, the weapon tests that you or ministers used to watch were tested many times in advance, and then the maximum power of the weapon was displayed in front of you. However, in private, a new weapon requires multiple tests. This process may be boring, which is why I did not notify you in advance."

When Zhao Shu heard this, he finally showed a sudden expression and couldn't help but speak: "So that's it. I remember when you watched the crossbow test firing, you could actually tell the range of different crossbows and the deviations that occurred when shooting out. I think it was because the following tests were done so much."

"Father is wise, but it is indeed the case!" Zhao Yan nodded immediately. Zhao Shu was busy with government affairs, so he naturally had no time to pay attention to small matters in this regard. However, now letting him know that some conventional work in weapon development is only beneficial and not harmful to military weapon supervision.

Zhao Shu was also a little disappointed when he heard Zhao Yan say this. After all, he still has a lot of government affairs to deal with, and he really has no time to spend on Zhao Yan. However, he soon felt a little unwilling to speak again: "Yan'er, can you let your father see the real power of the cannon, so that I won't go there in vain."

"This..." Zhao Yan showed a embarrassed expression when he heard this, but he quickly spoke, "Your Majesty, the accuracy test of the artillery will be carried out next. You can see the real power of the artillery, but I think you may be disappointed by Father Majesty, because this kind of artillery is still very primitive and has very limited power, and is even less powerful than the power of a crossbow."

When Zhao Yan heard that the cannon was not powerful, Zhao Shu couldn't help frowning, but he insisted on speaking: "It's okay, I know that nothing can be accomplished overnight, and the same is true for the cannon research. Yan'er, you can only give me some demonstrations, I'm ready in my heart!"

"Son of my duty!" Zhao Yan immediately agreed, and asked Qi Yu and others to prepare for the test firing again. This time, several broken cars were placed as targets a mile in front of the artillery. With the loud bang of the artillery, the shells flew out and drew an arc in the air and flew towards the target. Unfortunately, this time they might not be able to aim, or they had a lot of gunpowder, and the shells flew past the target and fell behind.

Although Zhao Shu hid behind the cover this time, he held a telescope and looked at the target in the distance. As a result, he saw an iron ball flying over the target with his own eyes and then bounced on the ground several times. Although he believed that the flying iron ball was also very powerful, there was still a big gap compared to the explosion of the crossbow shells. After all, it could only kill points and lines, but the crossbow shells could form a comprehensive killing within a range.

"Father, look, this is what the artillery is now. It can only fire solid bombs that cannot explode. In the future, we will study flowering bombs that can be launched and exploded. In addition, the range and accuracy of the cannon are also what we need to study. This may be a long process, but one day we can exert the true power of the cannon!" Zhao Yan introduced again.

"Well, although I was a little disappointed, I also saw some of the advantages of this cannon. First of all, although the function of this thing is similar to that of a stone thrower, its power is much stronger than a stone thrower, and it is much smaller than a stone thrower, and it is more convenient to transport. In addition, it is much stronger than a stone thrower in terms of accuracy, but compared with a crossbow, it is still a bit insufficient." Zhao Shu nodded at this time.

"What my father said is that it seems that artillery cannons cannot be compared with crossbows, but artillery has more development prospects than crossbows. For example, in terms of range, artillery may eventually increase to several miles, dozens of miles, or even dozens of miles, but the crossbows are not good. If you want to increase the range, you can only increase the size of the crossbows, and you will find that it is not practical at all. In addition, artillery has other advantages, which will be presented to people one by one in the future." Zhao Yan also said confidently at this time. No one knows the power of artillery better than him.

Seeing Zhao Yan's confident look, Zhao Shu couldn't help but feel a little confident in the artillery again. He immediately encouraged Qi Yu and other craftsmen, and then prepared to leave. Originally, Zhao Yan wanted to stay in the Firearms Department to record the performance data of the mother cannon in person, but Zhao Shu signaled him to return to the palace with him. It seemed that there was something important to discuss with him. (To be continued, please search for Astronomy, the novel is better and faster!
