Doomsday: My Shelter Unlimited Upgrades

Lin Tian had a normal conditioned reflex and instantly closed the system interface.

Listen carefully to the sounds in the shelter.

clack, clack, clack
The sound is very small, but it is getting faster and faster.

Lin Tian instantly understood the source of the sound, there was a leak somewhere!
After searching around in the shelter, Lin Tian locked on the target.

It's not a skylight, or a ventilation hole with a rain cover, but the stone door of the shelter!
The rotating wooden ladder has also been turned into stone during the last reinforcement, and one follows the stone staircase to the stone gate.

Lin Tian saw where the rain leaked.

After the stone door was closed, there were tiny gaps where it met the door frame.

Rainwater seeps in through this gap, but because the gap is too small, the speed of penetration is very slow.

Looking at the dripping water, Lin Tian suddenly frowned.

Isn't the system reporting acid rain? Why doesn't the rain look corrosive?
Acid rain is a very special disaster, divided into sulfuric acid rain or nitric acid rain.

Most of these disasters are caused by human activities.

A large amount of fuel with a very high sulfur content, vehicle exhaust, etc., all kinds of pollution will promote the formation of acid rain.

Acid rain, which contains a lot of acid, is highly corrosive.

Except for gold ore and other metals that are particularly resistant to acid, basically all substances are afraid of acid rain.

For example, the stone gate in front of you.

If it is acid rain that falls from the sky, at least it will be corroded with tiny traces.

However, why did the acid rain fall on Shimen and there was no response at all.

While thinking, Lin Tian took out a foot of white gauze from the warehouse.

At this time, it was left over from the last time the wound was bandaged, and there were a lot from the last transaction, and there are still many in the warehouse.

Carefully avoiding the dripping water, Lin Tian blocked the white gauze into the gap.

The water absorption of gauze is very good, it can not prevent the entry of acid rain, on the contrary, it can promote the penetration of acid rain.

The gauze was soaked quickly.

The doubts on Lin Tian's face deepened, it shouldn't be.

The main material of gauze is cotton, which is very easy to be corroded. Even a very weak acid will leave marks on the gauze.

What the hell is going on here?

Could it be that what fell was ordinary rain, not acid rain?

With doubts in his heart, Lin Tian took out the wooden spear from the warehouse and poked the wet gauze lightly.

Still nothing happened, and the wooden spear was not corroded.

Is it really normal rainfall?

Lin Tian reached out to tear off the gauze.

However, as soon as his hands touched the gauze, he felt a burning pain began to spread on his fingers.

Ah!
Lin Tian couldn't help crying out in pain, and retracted his hand reflexively.

It's acid rain!
I just don't know why, it won't cause harm to ordinary substances, but it is more dangerous to the human body!

After withdrawing his hand, Lin Tian didn't hesitate, took out the spiritual water from the warehouse in an instant, and washed the wound again.

Then he took 100ml of spiritual water orally.

After being washed by the spiritual water, the burning fingers relieved a bit.

He looked at his hand, and all five fingers on his right hand had turned black, and the fingerprints were completely invisible, as if they had been burned by fire.

The only difference is that the wound on the hand is still shrinking and tends to spread.

Fortunately, he treated the wound in time and took the spiritual water by mouth.

The wound on his hand has stopped spreading, and there is a faint tendency to recover.

He took out a wooden barrel from the warehouse and put it in the place where the water leaked. Lin Tian walked down the stairs and stretched his waist, moving his body a bit.

At the same time, he breathed a sigh of relief.

Since acid rain can only cause harm to the human body, there is no need to worry about shelters.

Nothing in the sanctuary will be corroded, nothing will be destroyed.

I just need to hide in the shelter with peace of mind, and wait patiently for the rain to stop.

Lin Tian returned to the bed and hugged Er Bai to his side.

There is no way of entertainment, he looked at the chat page of the system.

Just when Lin Tian discovered that rainwater cannot cause damage to ordinary substances.

The rest of the survivors also found out.

Some survivors felt that something was wrong, so they still hid in their shelters, watching the torrential rain coldly.

However, most of the survivors were excited.

It's been so long since they've had a drink!

Ever since I came to the survival game, fresh water has become a scarce resource. If you work hard for a day, the collected resources may not be able to exchange for a mouthful of fresh water.

How could they not be excited to see that the rainstorm falling from the sky was not acid rain but normal fresh water!
Excited and crazy expressions appeared on their faces, and they rushed out of their refuge.

This must be a gift from God!

A gift before the acid rain!

After rushing out of the shelter, some people raised their heads to the sky and opened their mouths wide.

The other part ran to the nearest puddle, picked up the stagnant water in the puddle with both hands, and poured it into his mouth.

They can't wait to drink up the water in one gulp!
