Back in the room, Jiang Chen closed the door casually.

A jade hand rested on his waist.

Feeling that coolness, Jiang Chen smiled and reached out to gently squeeze Liu Yao's hand.

"Not coming?"

"Can you still stand it?" Looking at those bright beautiful eyes, Jiang Chen smiled evilly.

Thinking of last night's bitter pleading, Liu Yao's cheeks were slightly red, but she pretended to be calm.

"I can bear it—"

"But I appreciate your happy expression more than I endure it. ”

A fleeting touch of emotion appeared on her face, and Liu Yao pouted slightly and lowered her head.

"Thank you. ”

"Let's rest early tonight, I'm tired from playing in the afternoon. Brushing the hair on Liu Yao's forehead, Jiang Chen smiled.

"Hmm. With a moist glint in her eyes, Liu Yao pursed her lips and nodded.

Half because of the money, half because of the people, but no matter what, she did love him. Although she knew that Jiang Chen would only regard her as a lover, she didn't care about anything.

She knew that his acceptance of himself might not have anything to do with love, and might even just be a tribute to his regrets, to make up for something that had passed. That day by the artificial lake of Wanghai University, she appeared in front of him wearing a milky white dress and pretending to be a student. From the misty look he looked at her, she could read the meaning.

However, none of this mattered, just the words of her lover, and she could still feel his tenderness.

The only thing that scared her was that deep down, he just used her as a tool to vent her up.

Thankfully, it doesn't seem like he did

After taking a shower, the two fell asleep.

At about twelve o'clock in the morning, Jiang Chen opened his eyes.

The sound of breathing in my ears was even, because too much energy was consumed during the day. Liu Yao slept very deeply.

Getting up lightly and getting out of bed, Jiang Chen put on a shirt, locked the door after entering the bathroom, and directly started the crossing.

The villa is quiet, and Sun Jiao and the others should have fallen asleep.

Without waking them up, Jiang Chen took a thick cold-proof suit and draped it over his body. Standing at the entrance of the living room, I adapted to the sudden temperature difference. Then Jiang Chen pushed open the door of the villa and walked into the snowy night.

Although it was late at night, the base was still brightly lit.

Under the heavy snow, the orange and yellow flames cast from the factory windows could not be hidden, and the "rumbling" sound of the workshop was faint. Backward production equipment can only be filled by manpower. The rudimentary production line can only be operated by the perseverance of shifts.

However, no one complained, because this is a wasteland. I can live with food and clothing, and I have the opportunity to pay for labor. It's more of a luxury.

Before the war, those highly intelligent unmanned factories were basically reduced to ruins in the nuclear explosion. Although Jiang Chen also thought about sending some people to the ruins of those factories to "pick up garbage", he still had to give up this idea when he thought that it was already more than ten years since the end of the world.

I'm afraid that all the good things that can be looted have already been scavenged.

From time to time, there are snowplows converted from vans and heavily loaded sentinels patrolling the base.

After seeing Jiang Chen, the sentry who led the team quickly stood up and took the lead in giving a military salute to him, the marshal.

"Don't worry about me. Just keep patrolling. Looking at the young man whose nose was red from the cold, Jiang Chen smiled and said.

"Yes!" the young man looked up, blushing. After another military salute, he walked forward with the warriors behind him.

From the young man's chest, Jiang Chen saw a bright gold medal.

Only then did he remember that he seemed to have canonized more than two hundred knights in the base. These knights, who were absolutely loyal to him, were the first few slaves to be bought from the Sixth Block, and were the forerunners of poking the first shovel in the ruins. Now these pioneers. has been promoted by Jiang Chen to the backbone of the base, serving as a manager or an upper-middle officer.

Behind the knight boy was supposed to be a high-class citizen, although he had not been implanted with a slave chip. But from those eyes, Jiang Chen still saw a strong sense of awe and worship.

"Is it already taking shape?" stood in the snow. Jiang Chen glanced around at the territory under his rule, and a smile rose on the corner of his mouth.

As the Fish Bone Base began to take shape, this fortress that was based on Jiang Chen had begun to expand the fourth new development area. The new settlement means that new immigrants can be recruited. Counting the group of survivors recruited from Shenxiang Town, the population of the Fish Bone Base is close to a thousand.

However, the development here is almost at a bottleneck, and the materials obtained by the garbage pick-up team are really not enough to meet the appetite of this imminent industrial behemoth. Only when he has obtained a base in this world can he bring tons of iron, aluminum and even rare earth ore to the end of the world.

After stopping for a moment, Jiang Chen walked towards Jiang Lin's aerospace laboratory, which was located at the corner of the base.

Standing at the door and ringing the doorbell, Jiang Chen leaned his face closer to the camera and said briefly.

"It's me. ”

Soon, there was a soft "click" sound from the door lock.

The door was pushed open, and the cold wind carrying the snowflakes swept into the room. Soon, however, the snow foam on the carpet was melted into crystal droplets by the heating in the house.

Closing the door casually, Jiang Chen hung the cold-proof clothes on the coat hook in the entrance, and then walked into the house.

"At such a late hour, I thought it was an accident on the mechanical exoskeleton production line. Jiang Lin, who was wearing pajamas, yawned and went downstairs with his messy hair.

Parts were thrown everywhere, so much so that the living room on the first floor seemed a little difficult to stand. But the sleepy-eyed fellow had easily slipped through the pile of bits and pieces, and had not stepped on a single screw.

It can be seen that this product is also out of a certain realm.

"What are these?" Jiang Chen pointed to the pile of parts and drawings on the ground in confusion.

Jiang Lin pulled out a chair for Jiang Chen, and then sat on another chair himself, and replied casually: "The K1-b mechanical exoskeleton you asked me to study is really, is this thing really necessary?"

The K1-b mechanical exoskeleton is an amphibious improved version of the K1 type. While maintaining the existing protection capacity, an anti-pressure layer is added throughout the body to resist water pressure. At the same time, the slot of the movable armor on the back was changed to a ring-mounted weight slot for the "cylinder" that integrated the underwater thruster and oxygen storage device.

This thing is naturally not used in the last days, but Jiang Chen didn't plan to explain too much to him, but directly asked about the progress of research and development.

"Does this thing work now?"

"Probably not, considering that the general radiation value in natural water now exceeds the standard, it is necessary to add a layer of heavy metal organic materials to the compressive protective layer-" Jiang Lin was ready to explain to Jiang Chen from a technical level. However, he was ruthlessly interrupted by Jiang Chen, who didn't understand at all.

"The problem of radiation aside, except that you still need to add that material, is this thing ready?" There is no radiation in the water in this world, and adding that anti-radiation material is purely superfluous.

"The design is completed, and the parts of each part have been sampled, and they only need to be assembled, which should be able to be used directly. After hesitating for a moment, Jiang Lin nodded and said.

"Then you can help me come out with a whole set of samples now, it should be fine, right?"

"No problem, no problem. However, the performance parameters have not been collected yet, so is it really good to put it into use directly-"

"Actual combat is the best way to test equipment. Jiang Chen said with a smile.

"Oh well. No longer persuading Jiang Chen, Jiang Lin shrugged his shoulders, got up and walked in the direction of the workbench.

The K1-b model's mechanical exoskeleton is much bulkier than the K1 prototype. Because considering that this amphibious equipment is mainly active underwater, the originally detachable polyethylene bulletproof plates are fixed to prevent water seepage in the gaps.

In addition, Jiang Lin also designed a heavier helmet for this set of armor.

In terms of shape alone, this mechanical exoskeleton basically envelops all parts of the body under compression-resistant materials. Except that there are no scroll engines, heavy steel armor that covers the whole body, and high-tech equipment such as neural access computers. This set of equipment is somewhat similar to power armor. By analogy, it is probably between "infantry light armor" and "heavy cavalry plate armor". The cost is probably a little more than three times that of the K1 prototype.

"Behind the propulsion equipment, charging the oxygen storage equipment only needs to make the interface contact with air. It can be fully charged in about one hour, and can be used for three hours after being fully charged. Jiang Lin pushed his glasses and explained to Jiang Chen one by one the equipment he had designed.

Can automatically supplement oxygen, lying in the groove, how against the sky?

Listen to Jiang Lin's explanation. Jiang Chen was secretly speechless.

"When there's a firefight, be careful not to get hit in the back of the neck with a respirator, of course, if you get a headshot, it doesn't make a difference. ”

"Isn't the helmet bulletproof?" Jiang Chen reached out and knocked on the helmet, feeling the texture of the special organic material.

"Underwater equipment, I have to control the overall density of the equipment, and the main bulletproof capabilities are concentrated in the chest and abdomen. Of course. The helmet should still be able to defend against a shot or two, but I don't mind you trying. With the kinetic energy of the rifle rifle, even if the helmet resists a shot, it is difficult for most people's cervical vertebrae to withstand that kind of compressive force. After all, this is not power armor. Jiang Lin shrugged his shoulders and said

"What about this pistol?" Jiang Chen picked up a weapon with a somewhat strange barrel shape.

"That's right, but it's underwater. ”

"Isn't the Type 11 pistol? I remember that thing had a lot of kinetic energy out of the chamber. Jiang Chen held the gun and played with it, feeling that the feel was not ordinary and strange.

Jiang Lin was stunned and glanced at Jiang Chen strangely.

"The higher the muzzle velocity of the bullet, the shorter the distance it travels in the water. Even if the bullets in the base are steel-core bullets, it shouldn't be crushed by water, and they will have to start rolling after a few meters, right?"

The more powerful it is, the closer it is?

"But I've seen it in the movie—" Jiang Chen said dumbfounded.

In his impression, the scenes of those machine guns suddenly forming a network of bullets in the water seem to be quite common in war movies.

"It's a movie, after all. Jiang Lin smiled and handed a box of thick bullets to Jiang Chen's hand, "With Type 11, you might as well use a laser gun." Although the energy of the laser projectile decays very quickly in the light-dense medium, it can hit farther than ordinary small arms. (To be continued......)
