"Try it?" Zheng Gongren smiled expectantly.

"How do you know our figure?" Li Mingxuan suddenly asked.

"This is simple, I know your approximate height and fat and thin, and then find a person who is about the same size as you to make a set of clothes, anyway, the material is tight, you won't have much discomfort when you wear it, if you can't change it, just fix it a little." Zheng Gongren said with a smile, he now has a large number of true scholars under him, and his manufacturing power is overwhelming.

"Good. Li Changfeng smiled and nodded, and then they went to change their clothes, and when they came back, they all felt that they looked very outrageous.

"Crystal goggles, big deals!" Li Changfeng touched the helmet on his face, the mask fit their faces tightly, but he didn't feel uncomfortable, all the pieces that fit were padded with a layer of cushion, and Li Changfeng didn't know the specific materials, I have to say that Zheng Gongren is a genius.

I also have to thank this martial arts world for its abundance of materials, which can replace the complex synthetic materials of the technological world, otherwise Zheng Gongren would not have been able to do this.

"Do you want to try the protection?" Zheng Gongren asked with a smile.

"How to try?" Li Changfeng had a bad premonition, and then saw Chen Qiankui and Lei Shiyu on the side walking out with sledgehammers in their hands, they were also wearing Zheng Gongren's original research clothes, and they were obviously also staff members of the True Research Institute.

"Offended!" The two of them came up with a wry smile on their faces, Li Changfeng and Lu Que flew out upside down on the spot, and there was surprise in their eyes, this hammer is not an ordinary hammer, it seems to have a bonus.

"Our world's magnets are much more effective than the technological world, so I created a weapon called the Magnetic Hammer, which uses the principle of repulsion of the same pole of the magnet, which can burst out in an instant with more power than you can imagine. Zheng Gongren said with a smile.

"I'll go, this dress is just against the sky. Li Changfeng stood up, even if he used the Sky Shield to resist the impact just now, he would be directly knocked out, but after wearing this set of clothes, the two of them were only shocked back by a distance of more than ten steps!

"Let's just put it this way, this set of armor with the body protection of Mo Yuan's predecessors, as well as your body protection and golden body duel, even if it is a blow from the foundation building monk of the cultivation realm, it can be blocked, of course, with the firmament crystal shield, you can be the strength of the Jindan monk without dying.

"That's true...... a Jindan monk instantly appeared in Li Changfeng's mind, and at the same time, the simulation also started in an instant, the strength of Jindan monk can directly shatter this protective suit, but the absolute defense of the firmament crystal shield can completely resist the opponent's power, and the remaining impact is not enough to kill him.

"This is just the beginning, you wait for me to research the intelligent system of our world, I can equip you with a set of intelligent terminals. Zheng Gongren said with a smile, the books that Li Changfeng reproduced from the Immortal Pavilion are all the technologies of the science and technology world, and every step is extremely detailed, and it is the crystallization of the wisdom of the science and technology world for thousands of years.

This kind of detail clearly records the manifestations of all reactions in physics and chemistry, and the things on it can be made by doing it step by step, but Zheng Gongren has to start with machinery first, and also bring the physics and chemistry into this world, so he must go to the cultivation realm, otherwise his lifespan is not enough for him to study these things......

"Now, I'm going to reveal to you the most powerful weapon I've ever made. Zheng Gongren proudly opened a huge box next to him, and there was an enlarged version of the sniper rifle in it, but this enlargement was an all-round improvement.

"This thing is powerful enough to shatter a mountain, it's the biggest guarantee I've ever given you, and if you want to use this cannon, you have to be among the machinemen. Zheng Gongren clapped his hands, and the sound of wheels turning came from the back of the house.

"This mechanism of Gong Ren shocked us for a long time just by the concept. Lin Yuanxu and the others on the side sighed.

As the voice approached, a huge humanoid mecha three people tall appeared in front of everyone.

"This is my ultimate secret weapon, the exoskeleton mecha!" Zheng Gongren laughed, and then he pressed a mechanism on the chest of the giant humanoid, and then the humanoid armor opened directly, revealing a space made for himself.

"What is most lacking in our world? It is energy conversion! We have no electrical energy, no nuclear energy, and no way to use things in nature, but we have energy and true qi in our bodies! In this way, I have developed a special device that can convert true qi to absorb the spiritual energy of heaven and earth. Zheng Gongren's voice was excited, and then his true qi instantly filled the humanoid mecha, and then this set of machine armor was directly combined.

And there is a terrifying energy around the armor, this is the energy of true qi, but it is different, Zheng Gongren is impressively converted his true qi from gas to a real energy, this energy is all over the entire armor, filling all the energy nodes he designed, and the mecha also jumped directly at this moment.

"I call this mecha, True Spirit!" Zheng Gongren's set of operations made Li Changfeng look stupid, he didn't expect the other party to be able to transform this kind of thing, it seems that Zheng Gongren has really created a new technology, real skills.

Harnessing the power of nature with true qi and the use of mechanisms is the core concept of true techniques.

And this kind of power that has never been discovered in the world of composite martial arts is true energy, which is similar to the energy manifestation of the technological world, and can completely do what these energies can do.

"Click. Zheng Gongren picked up Renfeng No. 2 and easily loaded it and set up this cannon-like sniper rifle.

"Come with me. Zheng Gongren stepped out of the True Research Center and came to the mountains and forests outside the city with everyone.

"Let's take a look at the power of this exoskeleton first. Zheng Gongren raised his hand and grabbed a huge stone next to him, and then directly lifted it, this stone was two circles larger than his current mecha, but it was directly lifted by him, which not only reflects the strength of this armor, but also reflects how strong the material of this armor is.

"Boom!" The boulder was thrown directly and smashed towards a mountain in the distance, Li Changfeng sighed helplessly, raised his hand and directly launched the reincarnation bullet, and wiped it out before the stone hit the distant peak.

"Nature...... It's better to destroy less. He realized that the development of true skills would inevitably pollute the natural world in the future, which he did not want to see.

"That's all. Zheng Gongren smiled confidently.

Then he opened his mouth and said: "True skills will not produce pollution, our human body will not destroy the natural world when it operates and absorbs the aura of heaven and earth, and the energy conversion machine I created is based on the meridians of our human beings as the basic structure to absorb the aura of heaven and earth, and then convert it into true energy." ”

"If that's really the case, then it's good......" Li Changfeng smiled bitterly, and then he stepped directly into the air and came to the opposite side, facing the muzzle of Zheng Gongren's Renfeng No. 2.

"Shoot, I'll feel the power of this sniper for myself. Li Changfeng said with a smile, and then he erected the Sky Shield, and Mo Yuan also appeared outside his body, and his current appearance has become purple-gray, which is also related to Li Changfeng's improvement.

At the same time, Li Changfeng's true qi protection was also ready, and the golden body duel had also reached the limit of the third layer, after he entered the realm of nothingness this time, he didn't have time to take the solid pill, so his strength was only improved to the third layer, not the fourth layer.

But these several layers of protection combined, but they can withstand the blow of the Zhuji monk, and now they are fully used to resist the shot of Renfeng No. 2, which is enough for Zheng Gongren.

"I trust your protection, take it!" Zheng Gongren directly raised the sniper scope and aimed at Li Changfeng's shield, and then, a bullet the size of Li Changfeng's calf was fired.

The speed was so fast that Mo Yuan and the Blood Ghost Impermanence had to concentrate to see clearly, except for Li Mingxuan's omniscient eye, no creature in this world could see the trajectory of this bullet.

"Boom!" Li Changfeng's figure was blasted out in an instant, and he was directly knocked down the hill and disappeared.

Li Changfeng, who was fully protected, couldn't even intercept it, and was directly blown away!

"This is at least the impact of throwing out a piece of metal with all his strength in the middle of foundation building!" Mo Yuan's eyes were full of shock, a sniper rifle that could really be supplied could reach this level, even with his knowledge, he felt a little difficult to accept.

"Ahh
