Early in the morning, 8:30.

Breakfast is a dehydrated vegetable soup with half a piece of compressed biscuits and half a box of lunch meat.

The taste is not too good, it is better to be warm and high in calories.

After breakfast, Lu Yu armed himself again.

Now his survival point has reached more than 400, and although he really wants to save up to 500, he will directly buy a copy of "100 Practical Skills Training for Craftsmen (Basic Edition)".

But when he went out, he found some footprints left in the stairwell outside the house.

The field of view of the monitoring ball at that position is not very good, and you can only see a little figure hiding in the stairwell to observe.

It doesn’t make much sense to use limited information to analyze who has been there, so it’s more appropriate to be prepared.

So Lu Yu purchased the biological intelligent access control from the Reincarnation Store without any worries.

The access control module is a small black box, similar to a mobile hard drive.

After taking it out of the portable space, the small black box was pressed directly on the inner wall of the room, and black nanoworms surged out of the box and climbed towards various parts of the shelter.

A light enveloped Lu Yu. After scanning his biological information, the access control was officially activated.

On his auxiliary panel, there is an access control icon.

Now he can close all the doors, windows and shooting holes in the apartment with just one thought.

At the same time, general violent ways to break doors and windows, such as lock prying, hammering, etc., cannot shake the access control system.

Then Lu Yu recorded the dog's biological information into the access control and marked it as a pet.

Lu Yu's identity mark is the owner, and visitors can be added in the future, etc. Different identity marks can use different access control permissions.

After adding a layer of security to the apartment, Lu Yu came to the apartment of Sim.

At this time, the Sim family and Frank's children were having breakfast, while Frank was still lying on the temporary renovated hospital bed, and his wife was standing by like a puppet.

The Sim and his wife quickly invited Lu Yu to have breakfast, but today's food was very different from yesterday's Mexican food.

Everyone only had a tray of batter, and it looked like some macaroni was added.

Sim's wife explained: "Although we have some food reserves, no one knows how long we need to live in this environment.

So now we eat exactly as planned in case the food is exhausted.”

Lu Yu nodded in praise, politely rejected the invitation to have dinner together, glanced at Frank, and said to Sim: "I'll go and see the project situation yesterday. You guys come to see me after breakfast."

Although the Sim family has their own conflicts, they get along well in general.

After leaving their house, a chill appeared in Lu Yu's eyes. When he glanced at the Frank and his wife casually, he clearly saw panic and nervousness in Jenny's eyes.

Could it be that Jenny, the one who went to observe Lu Yu's house last night?

Forget it, access control has been installed anyway.

Jenny is not very threatening at the moment, but taking action against her will affect the Sims' family.

It is safer to ask Sim's family to help renovate the building first.

Besides, with Lu Yu's current skills, these two families may not be their opponents when they join together.

After a night of freezing, the seal that was soaked in water yesterday turned into a solid ice wall.

There was no light on this floor, and it felt a cold feeling, which made Lu Yu not very comfortable.

Sim shouted Lu Yu: "Daniel, what's going on next?"

Lu Yu went upstairs and felt his body temperature had returned to normal: "It was chilly. Our seals and bulletproof boards had formed an ice wall with water. This is probably the best we can do.

Today, I will follow the plan and renovate your home first."

"Okay, do you have any opinions on the transformation?" Sim asked.

"I want to know your family's opinions first." After all, the purpose of renovating this shelter is to allow the Sim family to live here safely and become a barrier for Lu Yu. You have to consider other people's feelings.

Sim then talked about what happened last night: "Our apartment has two houses on one floor. Now, since we have to be on guard against threats from outside, I think we must connect.

Of course, we don’t have to live in such a large area. I think we can close the corridor and create doors that can be opened and closed.

Then several warm rooms for vigil were renovated in the apartment opposite, and stoves, fuel and food were placed to facilitate the rotation of vigil patrols at night."

While discussing and observing and measuring on the spot, the two quickly determined the plan.

Close the road leading to the lower part of the two stairwells and make two doors to facilitate inspection.

In the apartment opposite Sim's house, three can cover the view on the other side of the apartment, divide three small warm cubicles, and the floor is closed at the same time.

When the Sim family wants to live, they naturally have to put some thoughts on it, while the Sim family’s neighbors can use yesterday’s experience to create a solid ice wall by watering.

The division of labor in personnel has changed a little today.

Originally, Sim's wife wanted to join the task of finding materials and supplies, and let Sim's youngest son take care of the Frank family.

But Lu Yu still couldn't believe Jenny and Frank, so he adjusted it to Sim's family to be responsible for the construction, and Lu Yu went to collect the materials alone.

Yesterday, the Sim family had seen Lu Yu's efficiency. Although this efficiency has exceeded that of normal professionals, in this environment, since they chose to trust Lu Yu, they were very clever and did not ask more questions.

I have to say that this kind of tacit cooperation is amazing, although it is not professional enough.

However, the modification plan determined by Lu Yu and Sim is actually to absorb the successful experience of Lu Yu's family while eliminating the complex compartment plan.

The Sim family directly gave up the living function of several bedrooms, and all of them were closed and left with only observation and shooting holes.

Then the supplies and furniture were concentrated in the living room, and the family of four, plus Frank and the family of three did not seem empty.

Naturally, the new insulation materials used by Lu Yu's family were unable to be found, so they chose to use wooden boards and textiles to double-pin and nail them to the wall to improve the warmth performance of the wall.

The heating in the apartment relies on two large stoves and several small hand stoves transformed.

The Sim family was careful. Considering the situation of the Frank family, they mainly used Frank's hospital beds to separate a space with a curtain for their family.

Lu Yu asked Xim to leave a rectangular open space, Xu Nuo and others found suitable materials, so he helped Xim's family build a warm kang from the East - a warm kang.

While collecting the materials, Lu Yu also got a frozen turkey.

Although this thing has a bad reputation, Sim's wife's good cooking skills still turn the turkey into delicious food.
