    ¡­

    They were stunned for a moment, then smiled awkwardly.  most

    But when Li Chengqian was angry, it was inappropriate to laugh, so he held back his laughter.

    Li Chengqian continued to train: "Everyone has been divided into groups, so we can conduct multiple groups of experimental tests at the same time. There is no need for so many people to guard one. After each experiment, you can write down the data and hand it over together.  , discuss it again!¡±

    After finishing speaking, he pointed to the flat terrain around him and said: "Here, dig a deep ditch for me to get out. I just tried to find a safe ditch to lie down." "Fortunately, you failed."  , if you get it on time, you will all become a barbecue!"

    After he finished cursing, Li Chengqian paused for three seconds. They felt Li Chengqian stop and then asked: "Your Highness, there are five rockets here. Are we going to test-fire them?"

    When Li Chengqian heard this, damn!

    If the rocket had really landed just now, it would have caused the five rockets here to explode together.

    ¡°Tsk, tsk, these precious talents are all going to be gone!

    "Safety first, do you understand? You can't put all the rockets together here. If they explode, it will be all over." Li Chengqian cursed again, "Move to the side first, and just leave one tube here for test firing. Dig deep first.  Ditch, remove all the heads for me, only the necessary personnel will be left here during the test firing, and everyone else will stay away from me!"

    They should.

    Cheng Laoguo waved his hand, and engineers immediately ran up to dig trenches.

    The engineers began to take apart the heads.

    Li Chengqian, on the other hand, became someone he said was not necessary to stay, so he followed Cheng Laohuo and stayed away.

    After they finished it, they started test firing.

    After ejaculation.  They collected all the rocket debris and gathered around.  We discussed which crust would be most suitable.

    After they discussed it, they didn¡¯t even pay attention to Li Chengqian.  He carried a tube and ran back to the research room. It seemed that he had some inspiration.

    Li Chengqian was not angry at being looked down upon and just went his own way.

    When I came back the next day, I saw that they were conducting test firings again.

    A rocket was shot out, one hundred meters, two hundred meters, and the height was getting higher and higher, more than two hundred meters later.  He slowly slid down, flew five hundred meters, and then stuck into the soil!

    Li Chengqian subconsciously covered his face with his hands, but there was no explosion as he imagined!

    ¡°Oh, it seems that I¡¯m not pretending anymore.

    "Okay, it flew a mile away!" an engineer shouted happily.

    Another person said dejectedly: "It's misfired!"

    "Alas!" Everyone sighed together.

    Li Chengqian walked over and asked, "What's wrong?"

    "Your Highness, the fuse failed and the small explosion inside did not explode." said the chief engineer.

    Li Chengqian was about to speak.  The person over there who went to check on the rocket pulled the rocket out of the ground and waved a small red flag this way.

    ?Everyone knows that something is going on over there.

    After a while, they delivered it.  Said: "The fuse was broken by the shock. It may have been broken during the flight, or maybe the fuse was not arranged well. It was broken."

    With the reason, they quickly wrote it down.

    Next.  They conduct a test firing of the second tube.

    ¡°Clear the site!¡± an engineer shouted.

    So most of the people left the test range.

    Li Chengqian also left and reached the small shed in the distance.  Watching their skillful movements, after lighting the fire, the personnel quickly jumped into the ditch and hid.

    ??The observers and recorders stood behind a wall built and watched the situation of the rocket.

    The rocket spurted out flames and then flew out.

    The way it flies is no different from the one just now.

    It seems that they have fixed the outer skin.

    The rocket flew higher and higher, and flew farther and farther. Suddenly in mid-air, the rocket head flashed.

    Li Chengqian was stunned for a moment, but it didn't look like an explosion, so he waited a while and asked them what happened.

    The rocket was inserted into the soil almost a mile away.

    Li Chengqian walked over and asked, "What's going on?"

    "Your Highness, the head exploded prematurely again. Those are the fireworks that replaced the head." An engineer said.

    And halfway through the rocket¡¯s flight, someone had already run out to check.  There are small flags placed on the road as a mark of distance. Check the small flag. It exploded just above the third small flag. In this way, it exploded in advance at 300 meters.??.

    The other side waved the flag, and the other side immediately recorded it.

    Next, rockets were fired one after another, and records were recorded one by one.

    ¡°No less than thirty tubes were shot in one morning.

    This production volume is quite high.  It can be seen that Lao Li's side fully supports this side, and Lao Cheng has also tried his best to let this group of people deal with it.

    In the afternoon, another group of people came to experiment.

    This time, the distance of each rocket fired is different.

    This is to test the amount and angle of gunpowder and determine the distance.

    The same angle, different amounts of gunpowder, and the distance shot were all recorded.  This can be used as a parameter later.  When fighting, visually check how far the two places are. If you want to use this angle, then check the parameter table to see how many rockets are needed and which stage of the rocket is used. Then you can use it directly.

    Although the launch of a rocket, what parabola should be used to calculate it, please be careful.  But this thing is too complicated.  The data obtained from this practice is also quite useful now.

    While others were setting off cannons, Mr. Cheng sat in the p¨¢ngbi¨¡n and sighed, as if his wife had died.

    Isn¡¯t his wife Li Chengqian¡¯s future mother-in-law?  Pooh!

    "Haha, Uncle Cheng, what's wrong?" Li Chengqian walked over with a smile and asked, "Is it because the smell of gunpowder smoke here is too strong?"

    Could it be that you have bronchitis?

    ¡°It¡¯s so annoying to compare people to each other!¡± He sighed.

    Li Chengqian couldn't help but become curious. Is he angry?

    "How to say?"

    Today is a sunny day, the sky is very blue, and there are only a few white clouds on the horizon. Mr. Cheng looked to the northeast and said, "Old Hei Yuchi has left Chang'an!"

    Yuchi Laohei?

    Li Chengqian is very strange. What does he do when he talks about it?

    Cheng Laohao said another nonsense and said: "After I became the director of the Gunpowder Bureau, I will stay here all the time. Now the mission of the expedition originally belonged to me, but now it has been taken by Yuchi Laohei.  He was robbed. Not only was he robbed, but I also watched him go to the Northeast to act arrogantly, while I stayed here, like a nerd. This would kill me!"

    In the end, Li Chengqian understood.

    That¡¯s what happened!

    "The old man is suffering from old man's disease, and he is not willing to accept it.

    Li Chengqian would not comfort an old man.  But the old man found him and glared at him with resentment.
