Doomsday: My Shelter Unlimited Upgrades

"Share it, Mr. Lin Tian."

Fu Caiwei's message was replied quickly. The moment her message was replied, Lin Tian saw that the survival points to be paid had changed to 2 points.

After selecting the payment with the mind, a prompt of successful payment pops up on the interface.

Two points were deducted from survival points, 250ml of spiritual energy water was deducted, and there was an extra stack of blueprints in his warehouse.

Seeing this stack of nearly ten drawings, Lin Tian couldn't help but startled slightly.

I thought that the design drawings in one night would not be particularly amazing, but I didn't expect Lei Yingxiong to draw so many.

Rubbing apart the stack of papers, Lin Tian flipped through them one by one, feeling more and more surprised.

Every blueprint is drawn extremely carefully and neatly, and there is no trace of rushing work at all.

It is densely marked with various notes, explaining why it was built in this way, the benefits of building it in this way, and precautions during construction.

It's hard to imagine that this is a product designed in one night!

Lay the ten drawings on the wooden table in order, and the ten drawings are combined into a huge and complete drawing.

It includes not only the specific construction structure of the underground shelter, but also the underground protective buffer infrastructure that Lin Tian requested before.

The expansion of the underground shelter is based on the expansion of the existing shelter.

At this stage, Lin Tian's refuge is a square space with a height of ten meters and a length and width of ten meters.

But the refuge has been strengthened once, and the space has been slightly improved.

The current length and width are also equal, both are 15 meters.

The length and width are both 15 meters, and the ground area is more than 200 square meters. Although the area is not particularly large, it is completely sufficient.

And Lei Yingxiong's design is to not touch the 200-odd square meters at all, and take it as the most basic space, and make use of the height of ten meters.

His design is to continuously expand different spaces around along the spiral upward stairs, creating an effect similar to a duplex.

However, these spaces are on both sides of the main space, and will not affect the lighting and overall ventilation of the main space.

On the bottom floor, Lei Yingxiong deliberately marked a space, which is even 5 meters lower than the bottom floor.

This is the soundproof room designed by Lei Yingxiong.

In the soundproof room, Lei Yingxiong also specially marked that the surrounding walls of the room can be filled with plant fibers. Plant fibers have a good sound-absorbing effect and can reduce the intensity of noise by about 30.00%.

Lin Tian also felt that this method was highly feasible.

Buried five meters deep underground, no matter how loud the noise of the generator is, it should not come out.

Looking at the overall design of the underground shelter, Lin Tian nodded in satisfaction.

Lei Yingxiong's design is very practical. Designing on the basis of the original means that there is no need to re-plan the shelter, which is a good thing for Lin Tian.

Moreover, his design retains aesthetics while taking into account practicality.

Satisfied with the design of the underground shelter, he set his sights on the buildings on the ground.

Lei Yingxiong's design for the buildings on the ground is nothing new.

There are only a few classic defense measures.

Moats, walls, trenches, traps.

Classic, although not necessarily the best, but there must be no particularly big mistakes.

What Lei Yingxiong designed for Lin Tian is a combination of trenches and traps.

On the ground of the refuge, intricate trenches were dug, and camouflage was made on them to look like ordinary flat ground.

In the furthest trenches, make ground thorns and other mechanisms, not only will the enemy suffer fall damage, but also use special devices to send reminders to Lin Tian who is in the shelter.

In the shelter, Lei Yingxiong designed five exits for Lin Tian.

Except for the original main gate, the other four gates lead to different trenches.

If the enemy is lucky enough not to fall into the trench and keep approaching the refuge, then Lin Tian will start from the refuge and enter the underground trench without anyone noticing.

If the enemy is standing near the trench, he can attack directly from the trench, killing the enemy with one blow.

It doesn't matter if the enemy is far from the trench.

Lin Tian has a powerful compound bow in his hand, and he hides in the trench and shoots cold arrows. He doesn't believe that he can't kill the enemy with one blow.

Lei Yingxiong's design plan is perfect for him now!
It not only designed the construction of the shelter, but also drew the future development plan on the blueprint.

As long as he continues to develop his shelter according to the blueprint, the shelter will definitely become stronger and stronger!

This 350ml of spiritual energy water can be said to be worth the money!
Lin Tian carefully recorded the contents of the drawing in his mind, and carefully received the drawing into the warehouse.

Then, he opened the Survival Points Expansion System.

First build the silent room on the drawing and arrange the generator!
He has been hungry for electricity for a long time!
