Doomsday: My Shelter Unlimited Upgrades

"Required item: foam board."

"Trading item: 20ml of spiritual water per square meter."

"Introduction: Mass Acquisition!"

Foam boards are very fragile though, and foam balls flying around after damage are very annoying.

But it is an item that looks useless at first glance, but actually has great uses!

For Lin Tian, ​​there is nothing better than foam board to fill in between the insulation cloth and the ceiling.

Its heat insulation is definitely much better than that of air.

A thin layer of foam board can effectively insulate most of the heat.

It's just that this thing is hard to find!

In the context of the coming cold wave, the first thing that comes to mind for everyone to obtain such items must be themselves.

Not many people would choose to trade with him.

Forget it, let's go!

After Lin Tian announced the transaction, he turned his attention to the warehouse and continued to count the items obtained in the transaction.

However, among the remaining items, there was nothing that caught his eye.

It's not that the value of these things is not high, but that these things are not rare for Lin Tian.

Like food.

Now, there is a lot of food in his warehouse.

From raw meat to cooked food, from canned food to instant noodles.

There's even an assortment of snacks.

Except for vegetables, his warehouse has almost most of the food types.

You don't have to worry about nutrition.

Lin Tian smiled lightly and shook his head, making a decision in his heart.

In the next step, you can no longer collect food for your own transactions.

Food is the most basic material to ensure survival, and now he has passed the period when he needs food the most.

For him now, the difficulty of obtaining it is already quite low.

There is no need to store extra large amounts of food anymore.

Making up his mind, he closed the warehouse and lay down on the wooden bed.

Lying on the wooden bed, Lin Tian thought about his future plans.

In another morning tomorrow, the trenches will be dug, and in another noon, all the supporting traps in the trenches will be arranged.

Then open the door leading to the refuge, and then the ground defense measures will be completely completed.

The construction of underground shelters is a very long-term thing, so there is no rush.

However, the cold wave is approaching.

I still have to speed up and collect more cold-proof materials!
When he thought of the coming cold wave, he couldn't sleep for a while.

The plant fiber was taken out from the warehouse and weaved.

Taking advantage of spare time, weave more clothes for yourself, and even make some cotton clothes.

These are very necessary!

While thinking, the movements in his hands gradually accelerated.

Already knitting quite a few garments for himself, he is becoming more and more adept at his craft.

A sweater appeared in his hands within half an hour.

After receiving the sweater into the warehouse, Lin Tian lay down on the wooden bed with peace of mind.

"Law of the End Calendar, January 1, 1 Year."

"It's the first time you use a workbench to make items, and the consumption of the workbench is halved, which makes you very happy. (Survival points +20)"

"You made a mechanical item for the first time, and it was very difficult, but you overcame it, (survival points +25)"

"You got a lot of rewards after killing the werewolf, you are very excited. (survival points +20)"

"You made a lot of money through the trading system and got (survival points +20)"

"You slept very peacefully last night, and your mental and physical strength have fully recovered. (Survival points +10)"

"Congratulations, you have survived another day and are evaluating what you did today. (Survival Points +50)"

"In the final settlement, you have obtained a total of 145 survival points this time, with a total of 145 remaining survival points."

Eleven days until the cold wave arrives!
Opening his eyes, Lin Tian stretched his waist and exercised his muscles, then looked at his survival points.

145 points.

Not too much, save it.

After getting out of bed and finishing his breakfast, he climbed out of the shelter and continued digging trenches.

The progress of digging the trenches has reached the last juncture, and it only takes the last morning to complete.

However, this last step is also the most critical.

Because, the last step needs to connect the trench with the shelter.

It is not difficult to open a hole in the stone wall of the shelter, it only needs to consume two survival points.

You can even spend some survival points to build a solid stone gate, just like the current gate of the shelter.

It's just that these are not the most critical and difficult parts.

The hardest part was dealing with the height difference of the trench.

The trench connecting the shelter part must be higher than the entire trench.

Only in this way, when it rains, the rainwater will not pour back into the shelter along the trench.

This point is also clearly marked on the drawing as a precaution.

It's just that it looks easy on the blueprints, but it's not so simple to do it in practice.

After Lin Tian received the drawings in the warehouse, he took out the shovel.
