"Twenty baht of mana in a quarter of an hour, it's almost enough for me to unleash the power of a wind blade in earnest. Shi Yuanji silently calculated in his heart, and couldn't help but be a little surprised. Wouldn't such a powerful machine be able to meet the needs of the army? What the hell is going on on over there? Need so much food.

"Four days from Yuanjiapu to Branded Plains Bay?" Dugu Ming wailed. "Hu Dan, this is crazy, right? Yuanjiapu is at least 1,000 miles away from Branding Yuan Bay, and it will take two months to use the old ship, and it will take 16 or 7 days to get on the new ship with our prototype, which is already very fast, and he still wants to be faster?"

Just when Dugu Ming and Yuan Rang complained, Shi Yuanji was pondering the doorway of the prototype.

The dragon pattern on the prototype is dazzling, simple and sophisticated. A half-human-high steel hollow cylinder with a large, sturdy cowhide piston that closes the cylinder tightly and is connected to a steel lever. The two holes in the cylinder were of unknown significance, and he was confused.

Dugu Ming held his chin with his hand and said with a bitter face: "I see, it's useless for us to worry about it." Hu Fashun called Xiao Shi over to participate in the research, you can just let Xiao Shi understand the principle of the prototype today. Maybe you can communicate and have ideas. ”

"Then why are you going?" Yuan Rang still didn't know Dugu Ming's thoughts, and said with a little sarcasm. "I heard that the teacher has a new disciple, and it's still a banshee, are you ......?"

"I'll go upstairs and sort out the books, and you take Xiaoshi to do a good job. Dugu Ming said as he left the basement with a smile.

Seeing Dugu Ming's anxious look, Yuan Rang couldn't cry or laugh. He turned around and saw that Shi Yuanji had already looked at the prototype and drew talismans in the air by himself.

"No, he's not drawing, he's using mana to copy a prototype. Yuan Rang looked at it and couldn't help but be surprised.

The basement of the Pavilion is not completely underground, but is built at the bottom of the white marble pedestal, in order to be secrecy and not disturbed, but at the same time it is easy to access.

Yuan rang opened the window and let the sunlight fill the entire basement so that Shi Yuanji could draw the prototype. At the same time, he took out all the information so far and put it in front of Shi Yuanji.

"Yes, you don't know how to do it, you got most of the places right. Yuan Rang looked at the mana image that was gradually taking shape, and said happily.

"Senior brother, all this steel, the knowledge of aura, was taught to you by the master?" Shi Yuanji asked suddenly.

"That's not it, these are all from my spiritual science. I used to study in the spiritual weapon department, but now I am preparing the sacrificial wine, so I transferred here. ”

How did a student of the Spirit Weapon Department come to ** here? Shi Yuanji's heart popped up with this question, and he immediately shut up. Because he remembered Dugu Ming's words, he no longer inquired about other people's secrets.

"Brother told me that the principle of the prototype is similar to that of a gun, but I found that it is more like a ......" He couldn't think of the right words to describe it for a while, so he had to frown and think, and even stopped the movements of his hands.

"Haha, it's more like a sail blown by a strong wind. Yuan Rang smiled heartily and tapped the prototype with his hand. "The principle of this prototype was thought up by the teacher, and the senior brother added and deleted the details, and argued with the teacher for a long time before determining its general structure. And I'm just designing it. ”

"In order to build this prototype, Prime Minister Hu Cheng gave full support, asked for money for money, and asked craftsmen for craftsmen, so that he could have his current achievements. But you know, I didn't exactly do what my brother had in mind. If I really used the principle of a gun to build this iron shell, then you wouldn't see me. ”

"Why? You have made a great contribution and been transferred to the imperial court?" Shi Yuanji said with a smile.

"What? If I do, you'll see me in the cemetery. Yuan Rang smiled bitterly and raised his hand to point to the steel on the desk.

"Senior brother is indeed a good hand in theory, but he doesn't touch the spring water with his fingers. He didn't know that if he did what he wanted, no steel would be able to withstand that much power now. What was made was not a combustion pump, but a moving iron shell!"

"I had no choice but to change the design and weaken the power of the combustion pump, which led to the current prototype. Even so, the new ship, equipped with a prototype, was twice as fast as the old one. But I didn't expect that Hu Danna was still not satisfied, it was really insatiable. ”

If Shi Yuanji could see his face, he would know that his face was ugly, and he would be scared. He scolded Hu Fashun in his heart, and at the same time he couldn't stop regretting it.

"Isn't this the same as the bottleneck of the magic gun? The magic gun does not need a powerful magic medicine, but a suitable gun pipe, and the combustion pump does not want a greater mana output, but a strong steel pump body. It's also my bad luck to always run into the same problem!"

Thinking of this, Shi Yuanji was almost grateful to **, if he hadn't stopped Dugu Ming yesterday, I'm afraid he would have jumped into this big pit a long time ago.

Seeing Shi Yuanji's panicked appearance, Yuan Rang comforted: "Don't be afraid, I peeked at your contract, and the content is the same as mine." Even if you can't do it when the time comes, you'll be fine. Anyway, you didn't contribute to this study, and naturally you don't have any responsibility. ”

"Really?" Shi Yuanji's pale face was a little bloody.

"Really. Yuan Rang said with a smile, and went back to his desk to pick up the steel and look at it. "Okay, all the information so far is here, see for yourself, I'll continue to ponder my research. ”

He condensed the mana in his hands, and slowly groped for the steel with the shadow cone, carefully understanding the structure inside.

Shi Yuanji calmed down and continued to paint his image.

Jiang Renyun bowed to Hu Fashun, he already had a separate research room in Ziweiyuan in the Chengyun Pavilion, which Hu Fashun and Tang Tai often greeted and asked for at the price of paying a thousand taels of gold a year.

"I heard that you are very close to the Eight Pillars Nation. Hu Fashun picked up the magic gun, fiddled with it, and asked coldly.

"I live on the same side as Dugu Xingongzi, and it's right next door, so we see each other often. Jiang Renyun bent down respectfully.

"Jiang Renyun, there are some things I have to make clear to you. Hu Fashun did not put down the magic gun, but put it on Jiang Renyun's shoulder. "Whoever steps on two boats will not end well. Everything you have now is given by Your Majesty and my father. I hope you can repay your kindness, but don't eat inside and out. ”

Jiang Renyun had a kind smile on his face and said happily, "I know." ”

"That's good. Come to my house tonight, let's have a good drink. My third sister misses you a lot. Hu Fashun put the hammer on the rack and left the research room.

As Hu Fashun's figure faded away, Jiang Renyun's smile gradually disappeared. He found that his value was gradually decreasing, and the benefits that Fa Gong had brought him were no longer rich.

"Do you want to ask the heavenly master for help?" he picked up the magic hammer and looked at it, thinking silently. "But He hasn't answered me for a long time, is He going to abandon me?"

"No, I'm still worthy, I'm a mortal under His protection. He passed it on to me, how could I be abandoned?

"Why is it that no matter what I do, someone will hinder me? The Fa Gong I made was questioned by those Qiu Ba, the Emperor of Heavenly Mandate only accepted Shi Yuanji and not me, and Hu Dan also ignored my love and just let his daughter fool me, why?"

"Hu Fashun, you are just Hu Dan's son, what qualifications do you have to command me? The moment I welcome the arrival of the gods and become the messengers of the gods, I will kill you all!"

Jiang Renyun's face gradually turned hideous, and he threw out the gun in his hand.

Although Shi Yuanji had been to Hu Mansion before, he was all guided by Hu Fashun. This time he turned left and right, asked for directions several times, and then walked to the door of Hufu.

He wore his newfound quiver robe, and his hair was re-groomed, and he tried to put on a decent appearance, though he knew it was a bit funny.

"It's Shi Gongzi, right?" The door of Hu's mansion was open, and the old man of the porter stood in front of the door, greeting him with a smile. "My young master said, let me welcome you, you come with me. ”

I only have a relationship with this old man, and he remembers what I look like, Shi Yuanji muttered.

"The old man has worked hard. Shi Yuanji bowed slightly, and followed the old man into the Hu Mansion.
