"Hey, who are you? It's you, stand there and don't move. The brass pointed to the rat who was stroking the cannon.

The mouse didn't raise his head and said, "I'm a friend of Li Tong, my name is Li Cannon, he didn't tell you?" ”

"Li Cannon? I haven't heard of it, but your name is the same as this thing. Brass laughed.

The mouse raised his head and said with a smug smile: "That's it, I made this thing, otherwise why is it called a cannon!" ”

Copper pipe: "Do you really know Li Tong?" ”

"What am I lying to you for!" The rat continued to look down at the cannon tract.

Without waiting for the brass to speak, the mouse continued, "Do you know how to use cannons?" ”

This time it was the brass's turn to be proud, he clasped his hands to his chest and said, "Aren't you called a cannon?" You also said that you made all the cannons, why don't you use them now? ”

The mouse saw that the copper pipe had a straightforward temperament, and he flattered the copper pipe: "You are still good!" Or I'll give you the name of Li Dacang? All you have to do is tell me how to use the cannon. ”

The copper pipe suddenly caught the mouse with his backhand, and then walked to Wujiang's room, and said, "Don't lie to people, the cannon was made by Li Tong's life, what does it have to do with you?" You lied to me, an honest man, it must not be a good thing! I'm going to let the master overtake you! ”

When the rat heard this, he panicked, Nima, wouldn't he die if he was to be overtaken? The mouse struggled desperately and said, "Man, I really know Li Tong, you don't know Li Cannon, you should know about the mouse, right?" I'm a mouse. ”

The brass pipe stopped and said, "I've heard of rats, but you will say that you are a rat, and then you will say that you are Li Cannon, without telling the truth, let the master overtake you!" ”

"Someone! Help me! The rat struggled hard, only hating himself for not practicing martial arts.

Moreover, the rat's hands were held by the brass pipe and placed behind his back, and the drug in his arms could not be used.

The copper pipe pushed open the door and said to Wu Jiang, who was sitting cross-legged on the bed: "Master, this person is a liar, I heard that you monks are specialized in dealing with this kind of wicked person, come on, surpass him!" ”

Wujiang couldn't help but laugh and said: "What is excess, that's called degree!" ”

The brass pipe muttered, "What is excessive, doesn't it mean the same thing?" Master, hurry up and recite the incantation. ”

Wujiang shouted a Buddha name: "Amitabha." ”

Then he said: "Copper donor, you let him go first, with me here, he can't do anything." ”

Wu Jiang could tell at a glance that the rat was a martial artist who didn't know martial arts.

The brass pipe let go of the mouse, and the mouse rubbed his shoulder, which was still sore, and said, "Master, I am really Li Tong's friend!" ”

The mouse didn't know about Wujiang yet, and when Wujiang heard the mouse mention Li Tong, he immediately became interested and said, "You first tell me what kind of person Li Tong you know." ”

The mouse thought for a moment and said, "He's just like me, he's a very smart guy, he's got a lot of ideas, he's a good assistant, and he's done a lot of work in the process of inventing explosives and cannons, but of course I'm the best, and without me, he wouldn't have been able to make cannons and explosives." ”

Wujiang looked at the triumphant mouse speechlessly, sighed, and said, "The Li Tong I know is a ruthless, treacherous, peculiar, and possessed some magical abilities. ”

After saying that, Wujiang stared at the door and stopped talking, the mouse looked back and said, "Master, no one, what are you doing looking at the door?" ”

"It's not a good habit to speak ill of people behind your back, Master!" Li Tong came in from the door.

The mouse hugged Li Tong excitedly and said, "You're here!" ”

Then he pointed to the copper pipe: "Tell this guy, am I your friend?" ”

Li Tong didn't know that these two had a conflict, so he said, "It's not my friend." ”

The mouse's eyes widened, and he heard Li Tong say again, "It's my brother!" ”

The brass pipe scratched his head and said, "It seems that I misunderstood, and I was offended just now." ”

The rat snorted, then nodded, meaning to forgive the brass pipe.

Wujiang looked at Li Tong in shock and said, "Are you Li Tong?" ”

Li Tong said: "It's Li Tong below, and it was me yesterday." ”

Li Tong won't tell Wujiang which is his deity, Lu Ziqiao said it well, go out with a trumpet, steady!

Wujiang opened his mouth, and finally all his doubts turned into a sigh: "Defeated in the hands of people like you, the poor monk admits it." ”

"Is the master's cultivation good?" Li Tong asked.

Wujiang said: "Thanks to your blessing to Master Li, the poor monk replied very well." ”

Li Tong knew that Wujiang was blaming him for hurting him, and he didn't continue to answer, so he pulled the mouse and said, "Let's go, I'm looking for you something." ”

Wujiang shouted: "Master Li, when can the poor monk see Jiang Liu?" ”

Li Tong turned around and said, "I will inform the master on the day of the execution, and don't think about it before that, master." ”

Then Li Tong pulled the mouse out of the room, pointed to the cannons in the room and said, "These are the cannons I told you." ”

The mouse said: "I already knew, Lixia mentioned it in the information I gave me, but how to use this thing?" ”

Li Tong said: "Let's find an open place, I'll let you take a look." ”

Or the place where the last time he experimented with the range of the cannon, Li Tong commanded the mouse, let him complete all the preparations in the early stage step by step, and then pointed to the cannon barrel and said: "The degree of elevation of this cannon barrel will affect the trajectory of the cannonball, which involves the binary equation in mathematics, I won't teach you, you first study it yourself, see if you can study a unique method for judging the trajectory of the cannonball, after all, you are a great inventor!" ”

The mouse puffed up his chest and said, "Okay, I'll try." ”

"Let's light the fire." Li Tong said.

At the moment when the rat finished ignition, Li Tong quickly covered his ears, and with a bang, the cannonball was launched, and the rat didn't have time to cover his ears, and his ears buzzed.

However, the mouse looked at the cannonball that was fired, and was very excited, and he didn't care about Li Tong pit him this time, and immediately looked for it all the way along the direction of the cannonball, and the cannonball shot out of the pit was still smashed on the ground, looking at the ground that was smashed out of the big pit, the mouse measured the depth with his hand, and then took out the pen, ink, paper, and inkstone from the backpack, and was busy for a while, and wrote on the paper: range - one hundred and fifty-one zhang, power - the ground pit is two feet deep, and it takes six catties of gunpowder and eight catties of shells.

Li Tong saw the process of the mouse taking notes, and said: "It's too troublesome, go back and make it the thickness of your little finger with carbon black, and then draw Xie on the paper to try, you may not be used to it at first, but it will be good slowly, it is definitely better than a brush." ”

The mouse said, "Okay, I'll try it when I go back, how far can you shoot a cannonball?" ”

"Ten catties of gunpowder were used, the firing range was more than 230 zhang, and the elevation angle of the barrel was 60 degrees."

"What are sixty degrees?" As a scientist, rats have excellent habits of asking questions if they don't understand.

"You see, this is a positive turn, divide it into ninety points, one is one degree, this one positive turn is ninety degrees, so many are about sixty degrees." Li Tong squatted on the ground and gestured with a branch.

The mouse instantly understood, thought for a while, and said: "Then the elevation angle of the cannon barrel just now is only more than 30 degrees, okay, just leave it to me here, I don't need you, I will definitely find you the right elevation angle and explosive weight." ”

Li Tong was naturally happy and said, "Well, after finishing this, I still have a good thing for you to see." ”

The mouse said excitedly: "What else is good?" Let's take a look at it together. ”

Li Tong stopped: "This is a reward, you give me the data first." ”
