Doomsday: My Shelter Unlimited Upgrades

Back in the shelter, Lin Tian immediately stewed the chicken.

Unfortunately, no mushrooms.

But the chicken soup with enough seasonings is still very attractive, more than twice as delicious as the chicken that Lin Tian caught for the first time.

This chick was caught by Erbai. In order to reward Erbai, Lin Tian took out both chicken legs and put them in Erbai's bowl.

Erbai happily wagged his tail, chewed and chewed the bones, and swallowed them into his stomach.

Seeing Erbai's eating, Lin Tian's appetite increased greatly.

After being swallowed by one person and one dog, a chicken weighing two catties was not enough.

Lin Tian took out the baguette again, soaked it in the chicken soup and ate a little before feeling full.

Lying down on the wooden bed, holding Erbai in his arms.

Lin Tian couldn't help but be filled with worry.

Today is over.

Tomorrow is another day to prepare for the arrival of acid rain.

Are you really fully prepared?
In this way, with worry in his heart, Lin Tian fell asleep.

"Apocalypse Calendar, January 1, Year 1"

"Through your own efforts, you have built a drainage channel to protect the safety of the shelter. You are very excited. (Survival points +25)"

"You are worried about the ventilation of the shelter, so you wrote a book about it and made a relevant plan. (Survival points +5)"

"Your pet has learned and completed its first autonomous hunt. You are very happy. (Survival Points +10)"

"You slept very peacefully last night, and your mental and physical strength have fully recovered. (Survival points +5)"

"Congratulations, you have survived another day and are evaluating what you did today. (Survival Points +10)"

"In the final settlement, you have obtained a total of 55 survival points today, leaving a total of 365 survival points."

With the sound of the system, Lin Tian got up.

Looking at the system menu, he was very excited with the 365 survival points.

Yesterday, he used 50 points to upgrade the drains, so there are 310 survival points left.

Add today's 55 and it's back to 365.

Although these points are not particularly large compared to the items in the manufacturing list, they are already a considerable fortune in Lin Tian's eyes.

He can spend at least a week with these points!
After a simple breakfast, Lin Tian and Er Bai came outside the shelter together.

When building the drainage channel before, not all the stone materials were used. In his warehouse, there are still more than 100 units of stone materials lying quietly.

And it doesn't cost much to just re-route short water channels and create umbrella-like shelters.

The rest will definitely suffice.

Holding a stone shovel, Lin Tian started today's work after letting Erbai continue to have fun everywhere like yesterday.

The first is to dig a diversion channel near the entrance of the cave.

This work was carried out quickly because of the previous experience.

Moreover, because of time constraints, Lin Tian also deliberately speeded up.

In just two hours, it was all dug out.

Open the system menu, take out the required stones, and consume 15 survival points.

A drainage ditch that was exactly the same as the spectacular drainage ditch made before appeared in front of his eyes.

Wiping the sweat from his forehead, Lin Tian looked up at the sun.

It's noon, it's time for lunch.

Frowning, Lin Tian dismissed the idea of ​​resting.

There is still half a day.

In half a day, the acid rain disaster will come.

The construction of the ventilation system must be completed as soon as possible.

Coming to the hole that had already been dug, Lin Tianfan looked at the system's manufacturing list, looking for items that met his requirements.

However, after searching for a while, I couldn't find it.

There is no item he needs on the crafting list!

Lin Tian couldn't help being stunned.

Why, why didn't I think to take a peek at the crafting list before?
Now, after so much effort, it is only the last step.

Could it be that all my previous actions will come to naught, and my ventilation system is doomed to fail from the beginning?

When he thought of the acid rain disaster that would come tomorrow, he was filled with fear.

In an instant, panic filled his brain.

clam down!

Must calm down!
Lin Tian soon realized that his thinking had fallen into a misunderstanding.

Regardless of whether it was a waste, Lin Tian took out some psionic water from the warehouse and splashed it on his face.

The cold spiritual water calmed Lin Tian down.

There must be other ways!

Lin Tian rushed into the shelter and took out his blueprint.

Now there are two puzzles.

One is to punch holes in the ceiling of the shelter, and the other is to make a cover to cover the void.

These two must be done together.

A ridiculous idea suddenly appeared in Lin Tian's mind, and he was not sure whether this idea was feasible.

However, the disaster is imminent, and it must be tried.

Lin Tian hurriedly ran from the refuge to the dug hole, took out the needed stones from the warehouse, and placed them beside him.

Then, staring at the void, I began to meditate in my heart.

This is the ventilation system, this is the ventilation system, this is the ventilation system
