"I studied it all night last night, and finally I came up with a musket. Zheng Gongren smiled and put a drawing in front of Li Changfeng, which he improved according to the various firearms that Li Changfeng gave him, although there are also various scientific and technological firearms in the Immortal Pavilion, but because they are too long ahead of their time, they cannot be produced synchronously, so they can only rely on Zheng Gongren to study it himself.

"This shape ......" Li Changfeng looked at the shape of the musket in front of him, this is obviously a copy of a certain weapon in the Nether, the appearance is almost identical, but the internal structure should be very different, but there are similar principles.

After all, Zheng Gongren has created something like a pity, so he designed two things, a firing pin and a bullet, and now after all, there is a new gunpowder formula, so black powder has also been replaced by him, and the black powder hidden weapon has completely become a hidden weapon called Thunderbolt, which is extremely powerful.

"Gongren, are you sure?" Li Changfeng looked at Zheng Gongren, the design drawings of this series were all improved by Zheng Gongren through his own ideas, if this weapon was created, then the era of this planet would be completely subverted.

"And that's not all. Zheng Gongren smiled confidently, and then directly took out a new drawing, Li Changfeng looked at the appearance of the drawing, and the corners of his mouth twitched twice.

"You actually basically restored the pistol?" Li Changfeng asked as he looked at Zheng Gongren in shock.

"Not only that, the mechanism can be used in combination with internal force, such a weapon, the bullets fired are far more than the original pistol you gave me, that kind of ordinary pistol, the bullet can even be easily caught by Shen Zhou, the strength is completely comparable to this new pistol I redesigned, but this larger weapon, it can't be compared. Zheng Gongren said.

"Can it be sent in a row?" asked Li Changfeng.

"Well, I managed to reproduce the entire part of the bullet so that the firing pin could be rebounded, and the good news is that the bullet can be made with only ordinary refined steel, but unfortunately it is too precise for me to do it. Zheng Gongren said helplessly.

"It's okay, I'll take care of the precision problem. Li Changfeng smiled confidently and said, Rao's body can't be like a nether machine, but Li Changfeng's current body is no longer an ordinary human body, and the toughness and precision have surpassed ordinary machinery, coupled with the assistance of divine thoughts, even if it is a weapon, he has the confidence to carve out various parts with a carving knife!

"Okay, then I'll continue to concentrate on research, and when I think it's reasonable, I'll give you all kinds of parts drawings that need to be completed. Zheng Gongren said with a smile.

Li Changfeng is really looking forward to the appearance of firearms now, ordinary pistols, even some slightly better armor can't be pierced, and like the armor worn by Changwu before, even the most powerful firearms in the Nether are difficult to damage much, at most they leave a few bullet marks on it.

After all, it is also something that involves the cultivation realm, and the things created by science and technology are naturally difficult to destroy, you must know that this kind of thing can completely violate the laws of physics, chemistry and biology, and the physical body of the cultivators of the Tribulation Realm can resist the explosion of the stars, and the armor they make is naturally terrifying, and even if this kind of armor really falls, I am afraid that it is really enough to subvert the era of their planet.

However, this pistol created by Zheng Gongren is mixed with the subtlety of machine techniques, which can inject true qi to increase strength, and can also play an extremely powerful role in fighting with martial arts.

Li Changfeng has read a lot of literature, many of which are war years on various planets in the Nether, that era was the era of martial arts and basic firearms, and naturally there were a large number of fusion types of martial arts, Li Changfeng just read a little, and he had an extremely profound and novel feeling.

If you can hold two repeating pistols, each shot can inject true qi and burst out with terrifying penetrating power, then the role it can play in battle is also very obvious.

Thinking of this, Li Changfeng couldn't help but want to laugh, but his expression was still calm, and these thoughts only wandered around in his mind

"Gong Ren, I want to make such a batch of bullets. Li Changfeng suddenly took out a pen and paper and drew a new bullet on it.

"Spiral?" Zheng Gongren looked at him in shock, and then he hesitated for a moment, but still came up with his own thoughts: "The warhead of this bullet needs extremely strong metal, according to the content you gave me, the age of this bullet is at least three eras higher than ours, are you sure that this is the case?"

"Well, this kind of bullet must be made of the toughest metal, because the purpose of this bullet is to kill cultivators. Li Changfeng had a strong killing intent in his eyes, he understood that it was impossible for ordinary bullets to penetrate the kind of armor similar to that worn by middle-aged men, and even Changwu's armor could not penetrate it, so he could only be like this.

"Okay, anyway, you'll do it when the time comes, I can't finish this kind of delicate work. Zheng Gongren said helplessly.

"I understand, you should rationalize these drawings as soon as possible, and then give me the drawings of the parts. Li Changfeng nodded, and then they continued to eat.

After breakfast, Zheng Gongren went to retreat directly, and Li Changfeng entered the gambling stone field in Du and began to buy a large number of stones, all the stones he thought were very good, all of them were bought, this time he did not let anyone accompany him, he came to the gambling stone field alone, although he was still recognized by many people because of his clothes, but he did not meet anyone to find fault.

The other partners also found a suitable place for themselves in the city, Xiang Hualing pulled Yun Xuerou Li Mingxuan Yingchan to go shopping on the street, this city is too big, it takes half an hour for the breeze horse to run from beginning to end, walking at an ordinary walking speed, I am afraid that it will take a year to visit all the streets.

Chen Qiankui and Lei Shiyu are walking around the city with Lin Yuanxu, even if they follow the long point of knowledge, Lin Yuanxu's current intelligence ability has reached the same level as Qianjilou, since he found out that he has this endowment, he has been working hard to improve his ability, so now he will not let go.

A time has passed, and everyone has their own things to do, which is very happy for them, and at the same time, it will not let them lose their minds.

Li Changfeng and Zheng Gongren would get together whenever they had time to discuss the progress of the weapon and what needed to be improved, and Li Changfeng would make a batch of parts every time to try to see if they could fit together perfectly, and at the same time check the problem.

The time is getting closer and closer to the Spring Festival, and the time of the banquet is about to begin, Li Changfeng and Zheng Gongren finally succeeded in making the prototype of a pistol here!

"It's successful!" Li Changfeng loaded the bullet, and then directly entered the state of divine thought, he wanted to experience the absolutely correct way to use the pistol.

With the sound of gunshots, the bullet flew out in an instant, directly into the trunk of a big tree, although it could not be pierced, but the power was considerable, and this was still without injecting true qi.

Subsequently, Li Changfeng fired a gun, this time the bullet contained the divine true qi in his body, and instantly pierced the big tree through the previous bullet hole!

"It's too strong!" Li Changfeng returned to his normal state, and then he and Zheng Gongren looked at each other, and there was indescribable shock and excitement in the eyes of both parties.

"This gun is only cast in fine iron, and since it has been determined that it is no problem, you modify it slightly, and I will make it out of rare metal. Li Changfeng said with a smile, the service life of ordinary guns made of fine iron is only 1,000 rounds, but pistols made of rare metal can even be fired tens of thousands of times without any damage.

"If only you could make a gun out of the Sky ......Crystal," Li Changfeng thought whimsically, and then, his thoughts were ruthlessly extinguished by Mo Yuan.

"With my current strength, I can't fight against the cosmic-level disaster, if I use my strength to make so many parts, it is estimated that this planet will be split by the lightning tribulation that has been attracted. Mo Yuan's words were calm, but there was a touch of human touch, it seemed that he was influenced by Li Changfeng and them during this time, coupled with the fact that he was able to communicate with Zhu Ye at all times, which made his thinking evolve very quickly.
