Doomsday: My Shelter Unlimited Upgrades

The drainage ditches just made by the system are spotless.

Under the sunlight, it reflects the white light belonging to the stone.

Lin Tian looked at the spotless drainage canal and was very happy in his heart.

Now, the project that took a day and a half is completely completed!
He took Erbai back to the shelter, sat on the wooden chair, and opened the system menu.

But then it closed again.

He originally wanted to trade some food to reward himself and Erbai for the two days of hard work.

However, he suddenly dismissed the idea.

There is still one day to go until the acid rain falls.

However, his own shelter renovation plan is not yet complete.

There is no clue about the establishment of the ventilation system.

It would be a waste of time to reward yourself now.

Taking a deep breath, Lin Tian took out a pen and paper.

This is a gadget I got in exchange for fresh water a few days ago.

Perhaps no one thinks that pen and paper can play a big role in the last days, and his owner also thinks that it is better to exchange it for a sip of water, so the price at the time of exchange was very low.

On the paper, Lin Tian drew a profile of his shelter.

His shelter was built on a small hill, which was the terrain he had deliberately chosen.

In order to be able to prevent disasters such as floods.

On the profile, Lin Tian marked the aqueduct he had just built, and also marked the position of the skylight.

Then, he closed his eyes and meditated.

How to build a ventilation system?
The establishment of a ventilation system not only needs to ensure ventilation.

More importantly, it cannot leak rain.

After closing his eyes and meditating for a while, Lin Tian suddenly opened his eyes.

How about adding a cover over the vent?
As soon as this idea came to his mind, his eyes lit up, he wrote and drew on the paper, and began to outline it.

In a few minutes, the prototype of a ventilation system appeared on the paper.

In his conception, ventilation still adopts the most primitive method.

Dig holes in the shelter.

Drill several holes to ensure adequate air circulation.

After these holes were drilled, iron ore was used to create a protective cover like a small umbrella.

Let the rainwater avoid the hole and flow to the side of the hole.

No, iron may rust under the washing of rain, in order to ensure long-term durability, it is better to use stone.

After writing down the precautions on the paper, Lin Tian continued to think.

Although the rainwater covered by the small umbrella did not directly enter the entrance of the cave, after it fell to the ground, it would inevitably seep downward.

Ultimately, it's still possible to infiltrate your own Vault.

After thinking for a while, Lin Tian began to write on paper again.

Next to the hole, a diversion channel needs to be dug to collect the avoided rainwater into the drainage channel.

In this way, puddles will not form in situ.

For half an hour, Lin Tian kept writing and drawing on paper.

Finally finally finalized.

Standing up from the wooden chair, Lin Tian moved his arms and cervical spine, which were slightly numb from sitting for a long time.

Came to the top of the shelter.

Use the stone door of the shelter as a location reference.

Lin Tian took out a stone shovel from the warehouse, drew four circular marks on the ground, and then dug.

The ceiling of the shelter is not very deep from the surface of the soil.

Lin Tiancai dug about [-] centimeters, and felt that the stone shovel hit a hard object.

Looking down, there was indeed a gray-white stone hard board exposed underground.

This should be the ceiling of the shelter.

After digging to this extent, Lin Tian did not continue down.

On the one hand, he really didn't have the tools to make holes in the hard stone.

On the other hand, he was also worried that his technology was not mature enough, and he would damage the force-bearing system of the shelter by chiseling and chiseling, which would eventually lead to a landslide.

Then it's not worth the loss.

Therefore, after cleaning up the mounds dug around, Lin Tian walked to another marked place.

With the first experience, Lin Tian also knew how deep to dig to be the end.

Therefore, his movements are also more skillful.

Over the course of several hours, four circular holes were dug.

Lin Tian stretched his muscles and bones.

Such long physical labor did make him feel a little tired.

However, this is just the pre-work done.

The next job is the top priority.

He looked up at the sky.

The sky was cloudless and filled with stars, but the moon could not be seen.

Today, it's time to rest.

Putting the stone shovel in his hand into the warehouse, Lin Tian greeted Erbai.

In the distance, Erbai ran over with a strange posture, as if he was holding something in his mouth.

Lin Tian looked carefully and couldn't help raising his eyebrows.

Erbai actually had a forbearance chick in his mouth!
The work in the afternoon is a delicate job, and Erbai's help is not needed, so Lin Tian asked Erbai to go and play by himself.

Unexpectedly, Erbai, who was playing alone, could bring him such a surprise.

After Erbai ran to Lin Tian's side, he opened his mouth and let go of the chick, circling and wagging his tail while rubbing against Lin Tian's trouser legs.

It seems to be asking for credit from him, and it seems to be eager for his praise.

Lin Tian lifted the chicken, which weighed about two catties, and patted Erbai's head.

Awesome!
