Zhang Chen obtained the drawings of the nuclear energy device from Cao Bing, and just now he also had a general understanding of the situation on the side of the Business Friends Alliance.

Zhang Chen is just a technician who designs drawings, and if he gives him a drawing, he can write the most energy-efficient and efficient printing program, but it is not a problem.

The really difficult thing is to design feasible drawings, you need to know how things should be put in, what kind of structure is suitable, and there will be no problems in the later stage and a lot of maintenance will be required.

And nuclear energy, once there is a problem, there is only one word to describe it...... "Boom!" ”

It's not a problem that the pool can be repaired after a trip to the test, and if something happens, all the evidence will be lost, and there will be no chance to find out what the problem is.

It is impossible for Zhang Chen to relieve such an extremely dangerous task in his life, but the reason why he still agrees is that he has put his expectations above the Heavenly Printer.

After awakening the sci-fi module, the answer they want may be directly answered with a drawing.

The Heavens Printer corresponds to the drawings in the sci-fi module......

So, it's not really impossible to achieve, the key is to awaken the sci-fi module first.

……

Since the Business Friends Alliance is still only a conceptual model in terms of products, and everything is in a state of ruin, Zhang Chen has nothing to do if he continues to stay here, so he said to Cao Bing and went back first.

After returning to the new base.

Zhang Chen installed the printer on the ground.

"Ready to print!"

"Please select a module?"

"Magic Module!"

"Please select a drawing?"

"Iron-clad armor blueprints!"

"Detected you have material: iron shell, tortoise shell, hard rat skin, printing ......"

……

Soon, five pieces of iron-clad armor were printed.

The protective plate of this armor is not steel, but an iron tortoise shell, which is harder than steel and lightweight.

Therefore, the printed armor is not heavy, and it is worn on the body like an ordinary down jacket.

Zhang Chen distributed the armor, "Put on the defensive armor, it will be safer to travel in the future, even if it is a bloody corpse, it is not easy to break through the defense." ”

"Brother Zhang Chen, is this also the armor you printed?" Wang Li had just trained, and was wiping his sweat with a towel at the moment, and asked.

"Let's see if it fits, if not, let's change it again."

Zhang Yuxi had also been practicing outside and went home, and Zhang Chen handed her the smallest armor.

Zhang Yuxi took the armor from Zhang Chen's hand and put it on his body, "It fits well, it's just too light, I don't know if it's strong?" ”

"There's nothing wrong with the hardness, you can try it with a dagger." Zhang Chen took out a dagger and scraped it on the armor, leaving no traces, but there were signs of wear on the dagger.

It is enough to prove how hard the armor was.

"When you hunt zombies tonight, you can test the actual combat effect of the armor." Zhang Chen said.

……

A long, dark alley is so narrow that it allows only two people to walk side by side.

Zhang Chen and Wang Li walked back and forth inside.

The three dogs hunched Xu Xuan, Zhang Yuxi, and Wang Huan and jumped on the roof above.

"This unexplored area is a township, and there are many such two-story houses, which are very close to each other, and it is quite inconvenient to walk." Wang Li had to lean almost sideways to pass. He is tall and big, and the muscles on his body are relatively thick.

In contrast, Zhang Chen walked in it with ease. He hovered half a meter above the ground, controlling his wings without touching the walls on either side, as a way to hone his flying skills.

Just after crossing a fork in the road, suddenly, a fierce beast swooped out from the side, knocking Zhang Chen to the ground.

It's a tiger!

Zhang Chen could see that it opened its bloody mouth and wanted to bite itself, so he hurriedly raised his arm to resist, only to hear a "clang", the tiger bit on Zhang Chen's arm, but the tooth failed to penetrate it, only leaving a slight scratch on the armor of the arm.

Only then did Zhang Chen see clearly that this was not an ordinary tiger, but a mutated tiger, with sharp teeth far greater than before. But such sharp teeth still only left a slight mark on the armor.

There is no need to explain how terrible the bite force of the tiger's sharp mouth is, let alone after the mutation. But the armor still completed the task perfectly, resisting the bite.

The armor is made from an iron-shelled turtle, which is composed of a variety of metal elements, including calcium, and is an alloy with extremely strong hardness.

The surface is polished smooth as a mirror, which increases the difficulty of being penetrated by sharp objects.

"The defense of the armor has been practiced in actual combat, little kitten, you can step back."

Zhang Chen's free right hand raised a bloody blade and knocked the mutant tiger flying.

On the abdomen of the mutant tiger, a living hole was torn out by the blood blade, and blood was dripping outward, it felt the strength of Zhang Chen's strength, and slowly took a few steps back.

Suddenly, when the mouth of blood opened, a ball of lightning that continued to express was quickly condensed in its mouth. Then, like a sneeze, it sprayed in the direction of Zhang Chen accurately.

Zhang Chen's wings shook, and a sound sounded in the air, and in an instant, he dodged to another position, and the lightning ball sent out by the mutant tiger hit the house, leaving a huge gap in the wall, and the furniture placed inside could be seen.

"Some abilities, this tiger is dangerous." Zhang Chen felt that he had just called it a kitten, was it a little disrespectful, this eye-catching white tiger did not look like a kitten at all.

Then there is no way but to obliterate.

A group of blood bats struggled out of the blood-colored vortex in Zhang Chen's hand and attacked the mutant tiger.

"Roar! ~" The mutant tiger opened its mouth to condense the lightning ball again, spraying towards the attacking blood bat.

Like ripples on the surface of the water, the blood bats rippled in circles, dodging the lightning balls.

I want to say that it has been entangled with a mutant tiger.

The mutant tiger roared and raised its claws to slap the blood bats in the air, shooting down one or two.

But as time passed, the mutant tiger's movements became slower and slower, until finally it stopped moving completely.

The blood bat devoured the mutant tiger, and Zhang Chen also got the energy replenishment, and the blood qi lost by the eliminated blood bat was completely made up for at once.

"Yes, Brother Zhang Chen, this armor is a good deal!" On the side, Wang Li was holding his fist gauntlets, fighting with a much smaller mutant wolf, the wolf's sharp claws and sharp teeth could not break through the armor's defenses and hurt him, and he didn't even leave a trace on it.

Wang Li punched one punch after another, and finally killed the mutant wolf on the spot.

"Is there a zoo around here, where are the mutated tigers and wolves?" Wang Li asked.

Strike!

A mutated lion flew down from the roof, fell to the ground and let out a whimper, and then lost its breath.

Wang Li's neck shrank, and he was startled, even the mutant lion appeared, if it was the lion who was fighting with him just now, it would not be so easy.

The three-headed dog jumped from the top of a bungalow and roared.

The mutant lion just now was slapped away by it at random, and it was obviously either killed or killed.

Mutant animals are different from zombies, and their vitality is not so strong.

After the roar of the three-headed dog, there were some shadows of animals stalking around them, slowly receding, and they felt the strength of the three-headed dog.

However, a blood-red monster rushed out of the wall that had been broken before!
