"Good morning, cousin!"
"What are you..." Tang Ping looked at Li Tai, who was wearing glasses and holding a cup of coffee, and asked uncertainly: "You haven't slept all night?"
"Well, this refreshing thing called coffee that my cousin mentioned is really good. After drinking it, I really don't feel sleepy anymore!"
Li Tai said, pointing to the five or six torn instant coffee bags on the table.
Tang Ping was speechless for a while. He had no intention of giving this to Li Tai. Li Tai asked about it when he was drinking it that day, so he mentioned it casually.
Yesterday, Li Tai was reading downstairs. When he went upstairs to rest, he asked him to take a rest as well. The little fat man promised well, but he actually got so much coffee to drink in the store one night.
I just came into contact with coffee. It’s strange that I can fall asleep after taking such a large amount.
Li Tai is like this now. He hasn't slept all night. Instead of being sleepy, he seems a little excited.
"Cousin, I analyzed the reasons why the battle in Baozicheng was unfavorable."
Originally, he was going to send him to sleep, but when he heard what Li Tai said, Tang Ping said curiously: "Oh? Tell me."
"The first thing is that the Divine Power Cannon of the Tang Dynasty is affected by the weather." Li Tai adjusted his glasses: "At the beginning, my design was always aimed at the use of our Tang Dynasty siege warfare. I wanted to increase the range of the Divine Power Cannon. The longer the distance, the greater the power, and the easier it is to break through the enemy's city wall, which makes the divine cannon bigger and bigger and subject to more and more restrictions."
"In addition, the gunpowder of this kind of muzzle-loading gun needs to be poured into the gun from the muzzle. Once the weather is rainy, the inside of the gun barrel will be damp, which will affect the firing."
Tang Ping knew all this, and he asked, "Have you figured out a solution to the problem?"
"Well, when we were defending, we didn't actually use such large divine cannons. The number was too small. Although the power of a single shot was strong, the actual deterrent effect was far greater than the actual lethality. After thinking about it, it was better to use the cannons Make it smaller and increase the number to improve coverage and achieve the purpose of enhancing lethality."
As he spoke, he pulled out a drawing he had drawn: "I wonder if it would be better if the cannon were made smaller and specifically used to target sergeants."
Tang Ping looked at Li Tai's drawings and felt that he had forgotten something important, but he couldn't remember it for a while and could only say: "Is there anything else?"
"There is also the way you mentioned that Xue Rengui and the others attack from the air this time. I think this is the most powerful in the future. Because when you are in the sky, others cannot attack you, but you can attack the enemy infinitely, you Just invincible.”
Although Li Tai had never been in contact with the Air Force, he immediately saw the advantages of the Air Force.
Tang Ping nodded and admitted: "Yes, but the hot air balloon now has too many shortcomings. It takes off slowly, has no way to turn, and the direction of movement is also affected by the wind direction."
"So I thought about it. To use this in actual combat, we just need to modify it according to its flaws."
Li Tai clapped his fingers: "First of all, there is the problem of slow lift-off, because we are using hot air now. Hot air is lighter than air, so it floats. But there are other things in the chemistry book you gave me, cousin. There are many kinds of gases that are lighter than air. If we can create gases that are lighter than air, fill them up, and add them to the balloon when it is needed, wouldn’t the balloon be able to lift off directly?”
Tang Ping looked at Li Tai blankly. Is this the difference between academic masters and ordinary people?
"What gas do you think is better?"
"I took a look. Helium and hydrogen are both good, but hydrogen is a bit dangerous. Helium is the best. I read in a book that nitrogen can be produced by membrane permeation. If my cousin can find such a membrane, we can try it. Make helium."
Li Tai actually gave the most standard answer in one breath. You must know that many hot air balloons we use now are filled with helium. He even knows the membrane permeation method and has even thought about how to make it.
Tang Ping felt that he had become accustomed to Li Tai's monster, and now he realized that his situation was still small.
"As for controlling the direction..." Li Tai picked up a balloon found on the table in Tang Ping's shop, puffed up his fat cheeks to blow up the balloon, and then let go.
The balloon flew out with a whoosh.
"Cousin, look, if the air blows from the back of this balloon, it will fly forward. If we add something under the hot air balloon that can blow air or air to the back, wouldn't the hot air balloon be able to fly forward? If we Then use something like a rudder to control the direction, and the problem will be solved."
After listening to Li Tai's words, Tang Ping really doubted whether this kid had thoroughly studied something called an airship. Isn't this the helium airship he was talking about?
"What do you think is a good name for this?" Tang Ping asked. "Name?" Li Tai was stunned: "Isn't it a hot air balloon? What's its name?"
Tang Ping took the pen in his hand and drew on the paper: "Look, our hot air balloon is a round ball now. You have also learned about resistance. You should know that the resistance will be very large in this way, so we can How about making it look like a ship and then calling it an airship?"
"Cousin, you are so smart!" Li Tai looked at Tang Ping with surprise.
Tang Ping rolled his eyes at him: "Shuan Q, but I think people like you are scolding me when they say I'm smart. Also, the thing you mentioned already exists in our world, and it's called airships..."
"Next time I'll ask someone to see if they can make a smaller one and bring it over for you to study."
Now think about it, wasn't the first human aircraft an airship? If an airship could really be built, what would those East Vietnamese naval forces be? I will burn them all for you from above!
At this moment, Tang Ping finally remembered an important thing he had forgotten.
He asked Li Tai to wait, and then ran to the warehouse at the back. After a while, he took something and placed it in front of Li Tai.
"Cousin, what is this?" Li Tai picked it up and Tang Ping slapped him on the back of the head.
"Don't point the tube of this thing at people, it's called a gun!" This was the gun that the pangolin used to point at Tang Ping and the others. After it was confiscated by him, he didn't hand it over. After all, he couldn't tell clearly, so he simply threw it away in the big house. Don is here.
Li Tai just mentioned the smaller cannon, and then he remembered that he still had such a thing. Although it was just an earthen shotgun made by Pangolin's younger brother, it had a short range and was not very powerful, but it was used as a reference. no problem.
"You can also think of it as a shrunken cannon, specially used to hit people."
Li Tai's eyes shone, and he looked even more excited: "Cousin, let me study it."
Looking at Li Tai's appearance, Tang Ping remembered that he hadn't slept all night and was really afraid that he would die suddenly because of his own misfortune.
"Old Cui and Lao Du, send Li Tai to bed. If he can't sleep, knock him out! And if you see him drinking coffee again in the store, knock him out too!"
