A piece of red crystal in the suitcase, this thing also comes with relevant notes, and after reading it, Jiang Wei knows the importance and particularity of this thing.

She doesn't understand what the essence of life is, but this thing brings too many effects, which can make many people crazy, Zheng Yichen wants the research results of this kind of thing, all aspects are fine, if there are good results, then there is a chance to get a new essence of life.

】

As for the difficulty of obtaining such things as the essence of life...... It is very high for outsiders, it is not difficult for Zheng Yichen to get it, An Ke's side has a lot of shares because he has to do research, Zheng Yichen's side just went through an additional process, and there is a lot of information from the evil spirits, and those information involve evil rituals, and there is more than one.

That's what I wanted.

And although the evil spirit clones they caught before had enough knowledge, those knowledge was not as comprehensive as Elena's, and the hallucinogens that played a great role in Beihu were also separated from Zheng Yichen's body.

So the opportunity to exchange came, and the An family seemed very generous, not to mention that they gave a part of the essence of their lives, and they could exchange it for research results in another world with a higher level of science and technology, no matter how it was said, it was not a loss.

"Rejuvenation, healing...... This thing is so hot. Jiang Wei handed the suitcase to the little assistant next to her with some confusion, and it didn't take long for her to receive a message, the content of the message was to ask Jiang Wei Zheng Yichen for additional questions, asking him if he needed a stronger and more lethal weapon......

To protect the family and the house, it is still necessary to prepare weapons of mass destruction.

"It's too realistic, isn't it?"

Jiang Wei muttered, and added this message to the message at random, but Zheng Yichen had already left and did not reply, Jiang Wei didn't care about it, she yawned and returned to the atrium of the Dusk Church: "Now it's time to close the net against the infiltrators, I'm a little numb here." ”

She can stay out of the house for a long time with a computer, but she's been here for a long time lately, and she occasionally wants to go out for a walk.

"Yes, it'll be fine for a week at most." Jiang Wei's little assistant replied seriously.

Jiang Wei sighed and didn't say anything more, there are people who make trouble all the time, and there is nothing to complain about these things.

Hazy City.

Zheng Yichen, who was driving the truck, returned to his residence and began to get busy, he rubbed his hands and opened the carriage, looking at the modular boxes inside, these boxes are extremely heavy and need a forklift to transport, but Zheng Yichen's current physical strength can compete with forklifts, and he doesn't need that kind of thing.

In order to make transportation convenient, these things have been 'compressed', which will affect the efficiency of assembly, but Jiang Wei has already taken this aspect into account, she left Zheng Yichen a hard drive, which has the details of these modular boxes, with artificial intelligence Lilith, enough to complete the assembly and use with the fastest efficiency.

There are also several working robots in it.

"After the information is read, the boss can start work." The projection of Lilith's head said to Zheng Yichen.

"Then let's get started, by the way, I remember there's a large projection device in here, I'll install it first...... "That large projection device can be understood as a technological version of camouflage barriers, which can generate a camouflage projection covering a radius of ten to two hundred meters in the vicinity after installing this thing on the roof.

The larger the coverage area, the more electricity is consumed, Zheng Yichen has a laboratory here, and the electricity used there is specially supplied, so he can fully afford this projection equipment.

After installing this thing, Lilith has an additional projection screen, which shows a bird's-eye view of Zheng Yichen's home, and a cover is unfolded from the projection equipment as a starting point, quickly covering the laboratory here, forming a camouflage projection, and then it's time for construction.

Several working robots were on standby, and Lilith was not idle when Zheng Yichen went to install that thing.

"The project is expected to be completed in six hours."

"Oh, so fast?" Zheng Yichen was a little surprised.

"The weapon is already in a state of modular loading, which saves a lot of time."

The working robot began to dismantle those modular boxes, and the time savings Lilith said were for her artificial intelligence program, which is really not a simple thing for people, in order to compress the space, those modular boxes contain not a complete set of weapon parts.

Once all these modular boxes have been unpacked, the next thing to do is to find the corresponding parts in a large pile of parts, and then put them together into a set of 'home defense weapons'.

Those parts will be accurately recorded by Lilith, plus the information carried by the hard disk provided by Jiang Wei, modular packing is an efficient way for Lilith to save space and time.

The working robot quickly assembled some weapons, those robots were not completely humanoid, and there was no need to make them completely close to humanoid, but they did have both hands and feet, so that this thing could be used in other places after being used here.

After Zheng Yichen looked at those working robots for a while, there was an extra projection screen in front of him.

"Boss, you can dig holes in these places, and I'll help you with projections."

"It's not a big problem."

Zheng Yichen went directly to the place marked by the projection and began to dig the pit, and there was also a projection text in the marked place, which gave a detailed hint of how deep the pit to be dug was, what form it was, and so on.

I flipped through my skill list...... cough, the ability to master, the ability of the soil system is also there, and it becomes very easy to dig a pit with the assistance of this ability, after Zheng Yichen dug the pit, a working robot sent the adjusted cement over, this thing is also provided by Jiang Wei's world, which is specially used to build special fortifications.

Use it here...... Anyway, Zheng Yichen felt that it was not wasteful, just right.

With the assistance of follow-up projection, Zheng Yichen quickly completed what he had to do here, and then went to another place where he needed to dig a pit or smash a wall, and then there would be a corresponding working robot to deal with the place that Zheng Yichen had dug up.

In this way, it was busy until dawn, and those modularly packed weapons were also completely installed, and the weapon systems for preventing and controlling the ground were all in place.

"Boss, some materials are missing."

"Huh? Ammunition? Zheng Yichen asked.

"Yes, and some building materials." Lilith unfolded a projection screen in front of Zheng Yichen, the projection screen showed some specifications and drawings of ammunition, as well as the building materials needed, Zheng Yichen smashed a lot of walls, and those places needed to be filled with corresponding materials.

"Wait for me to call." The building materials are simple, Zheng Yichen was sent by someone with a phone call, and the speed of delivery was very fast on the premise that the money was enough, as for the camouflage of the projection device on the scene, as long as it was not directly touched, there was no abnormality from the outside world.

As for things like ammunition, just hand it over to Angel, this batch of weapons comes with basic ammunition, but if you really use these weapons, the consumption of ammunition is very fast, and these that come with the foundation can't be used to output half a round of time.

After finishing the follow-up, it was already noon, and Katrina couldn't help but come over to see the excitement, but she didn't understand the weapons that Zheng Yichen was fiddling with, but she knew that those weapons were very powerful, and they were what Zheng Yichen had been saying two days ago to protect the house.

She didn't expect Zheng Yichen to install these things overnight after getting them back.

"Lilith left the main control system in the lab, and you both will look at the tutorial then." Zheng Yichen held a hard disk in his hand: "But the automation is not so reliable, and manual operation is still needed." ”

At night, the ammunition needed for the weapon was sent over, and Anqi's work efficiency was not said, and the specifications of those ammunition were not very harsh, and it was not difficult to produce.

Since the house defense weapon can be used, Zheng Yichen is a little itchy and wants to give it a try, and he has a murderous intention with a sharp weapon......

"The mock test went well." Lilith made a final test report for Zheng Yichen.

"After all, it's a mock test, forget it, it's best not to use these weapons." Zheng Yichen glanced at his own environment, those working robots are worthy of being professional, after installing weapons, from the appearance of their own house has not changed much, but if there is any enemy who wants to invade this side, it is another matter.

The weapons were loaded, and the follow-up things were almost resolved, Zheng Yichen packed up his things and prepared to set off directly.

"It's so late now, can we wait until tomorrow to leave?" Katrina said with some hesitation, Zheng Yichen didn't come back this time soon.

"It's not a business trip to work, it's just to deal with some personal things, and I'll be back in a few days." Zheng Yichen said this and hugged Katrina: "If you're lucky, maybe I'll return to normal when I come back." ”

The girl who was held in Zheng Yichen's arms nodded lightly, Zheng Yichen's hallucinogens contaminated from the sandworm have not been completely decomposed yet, and that kind of thing is a big obstacle to the inability to get close to each other.

"How careful you are." After Katrina finished speaking, she left Zheng Yichen's arms, quickly returned to the house, came to the workshop, and took out a set of newly made talismans.

The experiments will be kept in the lab for the time being, while some of the more special items will continue to be kept in the workshop.

Zheng Yichen took this set of talismans, reached out and touched Katrina's face: "Wait for me to come back." ”

After saying that, he rode on the motorcycle next to him, grabbed a helmet hanging on it and brought it to his head, there is now an extra pendant on this car, which is a rather thick box, which contains the suit that Zheng Yichen is preparing to deal with in a low environment.

This thing can be tried anywhere, so he didn't touch it when he installed the weapon.

On the way to the Dusk Church, Zheng Yichen called Angel Anke one by one, telling them that he was going out, especially Anke's side, so as not to have any arrangements for her to find her.

After that, he came to the Twilight Church, quite impatient, this was the first time he took the initiative to use the cross-border service of the Twilight Land, during this time he had not waited for the reply from Qi Xiangyun's side, and he didn't plan to wait until now, just go over and take a look.
