Ye Chen also asked curiously, "What kind of reward is it?"

Yang Qian waved her hand impatiently: "You will naturally know what reward you will do. Now, hurry up and tell me what the solution is!"

Ye Chen said as he walked: "Well, when I was learning to train tools in the sect, I accidentally got some carbon into the refined iron water when I was refining iron ore."

"At the beginning, I thought it would lead to the failure of the refining tool, but I didn't expect that after the iron was cooled and formed, it was much better than simple pig iron in terms of toughness and hardness, so I named this new thing steel."

"I'm sorry, seniors from my previous life, I have stolen your knowledge theory, hehe." Ye Chen couldn't help but think of this in his heart.

Then, Ye Chen told Yang Qian in detail about the steelmaking method he found on a whim in his previous life!

After listening to Ye Chen's method and steps of steelmaking, Yang Qian couldn't wait to take out a piece of star iron ore from his space ring. He casually used the weakened version of Samadhi True Fire, quickly refined the star iron in the ore, and then according to what Ye Chen said, he gradually refined the star iron into star steel.

Looking at the bright white and star steel seamless tube in front of him, Yang Qian's eyes slowly lit up: "It's really done!"

Then he stared at Ye Chen tightly...

The sharp eyes made Ye Chen take a step back in fear: "That, mentor, look, this steel pipe has also been refined, is it a reward..."

Yang Qian gave Ye Chen an impatient look: "I will give it to you, and I will give it to you then! Will I still break my promise? Isn't there two problems that have not been solved? I dare to ask me for rewards, right?"

Ye Chen quickly smiled flatteringly and said, "Well, you misunderstood by tutor. I don't mean that. Let's not talk about anything else, let's solve these problems first!"

"As for the range and accuracy issues you mentioned by the mentor, we can actually classify them as one type of problems to deal with."

"Teacher, you have been studying science for so long, and I believe you know the existence of air. Although the air cannot be seen or touched, it really exists! You don't deny this instructor!"

Yang Qian nodded, expressing her agreement with Ye Chen’s statement...

Then Ye Chen continued, "Since air exists, no matter what, when flying in the air, it will rub against the air and be subject to resistance from the air!"

At this time, Nangong Xue quickly raised her hand and asked, "Well, Brother Ye Chen, I want to ask, what is the friction you are talking about? What is the resistance?"

Ye Chen coughed twice, found an eye frame from somewhere, held a book, and said like a scholar: "Where is friction? It is easy to understand. When two objects in contact are in opposite movements, they will produce a force called friction."

"Well, let's give an example. For example, if your hand touches the wall, and then your hand touches the wall and moves forward, we will feel where our hands and the wall are in contact, as if there is a force that wants to pull our hands back. That force is called friction!"

"The friction may be a little abstract, but the resistance is better understood. I believe you have played in the water. When we want to walk forward in the water, we will feel as if water is blocking our progress, and the force that blocks our progress is called resistance!"

Listening to Ye Chen's explanation, Nangong Xue and the other three nodded in a sudden realization. It turned out that there was such a statement!

And Yang Qian even looked at Ye Chen with a look like she was looking at a rare treasure, as if she wanted to eat Ye Chen!

Seeing Yang Qian's terrifying eyes, Ye Chen couldn't help but shrink back in fear.

"So what you said has to do with solving the range and accuracy of the gun? It's not that the range and accuracy of the gun have not been solved!" Yang Qian asked.

Listening to Yang Qian's question, Ye Chen couldn't help but complain: "I'm too lazy to say that a broken thing is equivalent to a messenger-like crack in the Earth in his previous life. It can actually hit more than 2,000 meters, and its power is even more abnormal than the gun on the Earth in his previous life. It explodes, like a grenade!"

"You know, even the farthest gun on Earth on the previous life, Barrett's effective range is only about 2,000 meters! I have to say that this world of immortal cultivation cannot be judged by common sense."

But this is just a bamboo gun. Ye Chen is even a little unimaginable now what those more advanced guns will look like in the future!

Although he kept complaining in his heart, Ye Chen quickly explained the reason to Yang Qian: "What do you think! After firing the gun, when the bullet flies in the air, it will be affected by factors such as air resistance and friction, which will lead to a shorter range and low accuracy!"

"So the first priority to solve these two problems is to find ways to reduce the impact of air resistance and friction!"

"The first aspect to solve this problem is to change the shape of the bullet." As he said that, Ye Chen picked up a round bullet that Yang Qian put aside.

"First of all, we need to change the bullet from a round shape to a slender shape like a gyro, with a sharp front and thick back, just like a bow and arrow used in the army. In this way, the bullet can greatly reduce the friction of the air. At the same time, because the front is sharp, it can better break the air, thereby reducing the resistance of the air and killing the enemy more easily!"

Speaking of this, Ye Chen stopped and looked around, as if he was looking for something!

Yang Qian frowned and stared at Ye Chen tightly. After watching for a long time, Ye Chen still didn't look like he continued to talk, so he asked impatiently: "What are you looking for? Why don't you continue to talk!"

Then, Ye Chen looked at Yang Qian with a pitiful look and said aggrievedly: "That, mentor, look, I have said that I have been saying that I have not had to drink a sip of water. My throat is dry like a fire now! So..."

Yang Qian gave Ye Chen a blank look, took out a pot of spiritual tea from the space ring and threw it to Ye Chen. She said angrily: "Drink it quickly and then continue..."

Ye Chen smiled and took it, nodded repeatedly and agreed, "Yes, yes, I'll..."

After moistening his throat, Ye Chen said to Yang Qian: "That, mentor, I have a question to ask you!"

"What kind of question, please ask, if I know, I will tell you!"

"Well, what is the principle of launching your gun?"

"It's very simple. I engraved a formation that can generate force in the gun, and then put the bullet in. When pulling the trigger, you can touch the formation, let the formation be activated, and then shoot the bullet out in an instant!"

Listening to Yang Qian’s explanation, Ye Chen couldn’t help but thrust the corners of his mouth!!

It is indeed a world of cultivating immortals. Even the principle of shooting is so unscientific, but there seems to be a little scientific inexplicably in the unscientific.
