Global Wasteland: Sanctuary of the Immortal Emperor

Chapter 41 The shelter has been upgraded!The bunker is built!

The entire bunker, not to mention anything else, is just a semi-circular roof on the ground, which cannot be built by ordinary people casually.

The biggest reason for Su Mu to buy this bunker design is that after having the design, he does not need to do it himself, nor does he need to master any construction knowledge, as long as he provides the corresponding materials, he can directly build the bunker!
This is much more convenient than his time-consuming and laborious manual construction of shelters.

Swish!
With a thought, the design of the small bunker was used, and at the same time, the corresponding options appeared on the system's construction page:

【Small bunker】

【消耗材料：铁锭*30（剩余部分将由避难所现有材料抵扣）、木头*100、石砖*2000、混凝土*1t、钢筋条*30】

[Description: Upgrade your shelter into a small bunker, the shelter will have better defense capabilities after upgrading]

"It costs more than 2000 stone bricks...it's not cheap."

With a sigh, Su Mu rummaged through the exchange mall, and quickly found a stone brick that met the requirements:

【Natural Stone Brick】

[Price after discount: 5 activity points]

[Description: It is made of naturally formed stone. After years of vicissitudes, the texture has become extremely hard, and it is difficult to destroy it even with small explosives! 】

"Do you still need 5 activity points after the discount?" Su Mu felt a little pained.

If he buys [-] copies, it will cost a full [-] activity points, which is already one-third of his total budget.

but.

After thinking for a while, Su Mu climbed out of the underground shelter, gritted his teeth, and bought two thousand stone bricks.

This bunker needs to be built anyway, otherwise his current refuge will be like a cellar, and it will not be easy to develop in the future!
Bang bang bang!
Stacks of stone bricks appeared out of thin air, stacked in the open space around the shelter.

Su Mu didn't have time to check it, so he rummaged through the exchange store and spent [-] activity points to buy all the remaining cement, steel bars, iron ingots and other materials needed to build the bunker.

All of a sudden, the entire open space of the shelter was filled with various materials.

[Do you want to spend 300 points to upgrade the shelter to a small bunker? 】

"Yes."

Su Mu clicked to confirm with his mind, and then, white mist rose up, covering the construction materials in the entire open space.

After a few breaths, the mist slowly dissipated, and all the materials on the open space disappeared, and a semicircular stone fort made of stone bricks and reinforced concrete appeared on the spot, covering an area of ​​more than 30 square meters!
The stone fortress is about three meters high and is located on a stone platform with three steps of stairs. The overall appearance is similar to a yurt. It is bluestone in color and has an iron door on the front. There are gun holes on all sides for counterattacking the enemy. At a glance, it looks like Gives people an unparalleled sense of safety and solidity!

Although he had already seen the preview on the system panel, Su Mu couldn't help being surprised when he saw the bunker appear in front of him.

This bunker can be seen at a glance, it must be safe for thieves to live in!

"Ow!"

At this time, Xiao Sha's indistinct cry came from the bunker.

"It's broken, forget it inside."

Su Mu smiled wryly, stepped up the steps to the iron gate, and went up to jio.

duang!

There was a muffled sound, and the iron door remained motionless.

After kicking the heavy wall next to the iron gate to make sure it was hard enough, Su Mu opened the iron gate and entered the interior of the stone castle.

The interior has a total of [-] square meters of space, with wooden floors, and because the lighting is not very good, it is slightly dark overall.

In the middle, there is a stone staircase leading underground.

Su Mu walked down the stone stairs, and another iron door appeared in front of him.

Opening it, Xiaosha rushed out of it, scrambling around him restlessly.

Su Mu smiled, knelt down and stroked its wolf head, and looked inside the iron gate.

Because there was not much light, he could only see an outline of the interior, but all his belongings should be well placed inside, such as beds, tables and chairs, wooden boxes, generators, etc.

After appeasing Xiao Mo, Su Mu turned on the flashlight and took a closer look, and found that the underground part was slightly smaller than before by ten square meters, but everything else was as usual, with a rectangular structure, a wall height of more than three meters, and an all-iron wall noodle.

"Well, the ventilation pipe seems to be different."

Su Mu found four vents with covers at the four corners of the ceiling, about the thickness of a calf.

He thought for a while, and then returned to the ground. As expected, he found the other end of the ventilation duct near the four gun holes in the stone castle. The shape was exactly the same as his previous ventilation duct, except that one became four.

Under such a structure, part of the air flowing into the stone castle from the gun hole will flow into the underground shelter along the ventilation duct, which perfectly solves the ventilation problem, and because it is inside the stone castle, there is no fear of it being damaged. There is a case of rainwater intrusion.

unless……

The whole stone castle was flooded.

"If it's just raining, it shouldn't be able to flood the stone castle, right?"

Su Mu stepped outside and observed the height of the stone castle. It was about 50 centimeters above the ground. It was difficult to flood to such a high position with rain alone.

However, this does not mean that there is no need to build any drainage facilities.

In the case of heavy rain, the rainwater will still produce a lot of potholes or lake-like puddles around. These things will greatly affect daily activities, and if things go on like this, the accumulated water will seep into the ground and corrode the iron of the underground shelter. quality walls, threatening the stability of the shelter.

Thinking of this, Su Mu took out the design drawing of the drainage facilities that he had already prepared, and directly learned it with his mind.

The crafting options for the Drainage Facility soon appear on the crafting page.

【Drainage】

[Consumable materials: any material, such as stone, wood, iron ingots, etc., each unit of material can build a one-meter drainage channel]

[Description: Simple drainage facilities, the drainage effect is not satisfactory, and it can cope with normal rainstorms]

"It should be based on the different materials used, the material of the drainage channel will also be different."

Su Mu thought for a while, and bought 200 yuan of stones at the exchange shop.

Choose stone, one is that stone is cheaper, after half price, only 3 activity points per unit, and two, stone is easier to maintain rigidity than wood, and there is no hidden danger of rust compared to iron ingots, it is very suitable for use as a drainage channel of construction materials.

clap la la...

A hill of stones appeared around the bunker.

Su Mu tried to build it, and found that a 300-meter-long drainage canal would cost a full three hundred points!
If he wants to build four drainage channels, it will cost a total of [-] points.

"No, it's too expensive, and my remaining [-] points are not enough."

Su Mu frowned and thought about the solution. Suddenly, his eyes lit up and he thought of a solution!
