Doomsday: My Shelter Unlimited Upgrades

Following the system prompt, Lin Tian jumped up from the wooden bed refreshed.

He turned on the system and glanced at the record of survival points, and he was pleasantly surprised.

Unexpectedly, the system, which has always been stingy, would be so generous once in a while.

Just yesterday, he spent 500 survival points to repair the generator, and the survival points were reduced from 525 to 25.

He originally thought that he would need to save for a long time before he could reach the 300 points needed to build an energy bicycle.

But now he has a full 240 survival points!
In one day, an increase of 215 points!
Not surprisingly, 300 energy bicycles will be built tomorrow!
Lin Tian was so excited that he crawled out of the shelter and stood outside the stone gate of the shelter.

Today, no trenches are dug.

He has a new plan.

Standing on the hillside where the shelter is located, Lin Tian held a technologically advanced composite bow in his left hand, and was wearing a hand-knit sweater with a silver-white iron inner armor inside.

Erbai squatted at his feet, wearing silver-white plate armor, looking majestic.

At this moment, his confidence is unprecedented.

Goal, the treasure on the treasure map, let's go!
Leading Erbai, Lin Tian took out the treasure map from the warehouse and started to move forward according to the marks on the map.

Judging from the treasure map, the distance between his shelter and the mark on the treasure map is not too far.

So he quickened his pace, hoping to arrive as soon as possible, and then return to the shelter before dark.

As Lin Tian walked, he took out the treasure map from the warehouse to check it from time to time.

Make sure that the surrounding terrain is different from the map on the treasure map, so as to confirm whether you are on the right path.

Erbai didn't care about this, seeing that there was no danger around him, he kept leaping and running around Lin Tian, ​​having fun.

Lin Tian stepped up his pace very quickly, and they arrived at the marked location in just two and a half hours.

Standing at the marked spot, he looked around.

The surroundings are still plains, with endless yellow land, withered yellow weeds, and dying trees.

The surrounding scenery can be seen everywhere, and it is not different.

The only unusual thing is that there is a quaint stone gate at the foot of Lin Tian.

The stone gate was covered with a layer of yellow sand.

Lin Tian sighed while squatting down to study Shimen.

This ruin is hidden really deep!
If he hadn't held the blueprint in his hand, he would never have found the stone gate buried under the yellow sand.

At first glance, Shimen has experienced a long period of time and is covered with various scars.

There are nicks from the yellow sand falling by the wind, scratches from unknown animals, and even traces from the impact of water.

Although he didn't know how the traces of the water impact came from, he confirmed one thing.

This ruin is by no means simple!
Lin Tian was more vigilant in his heart, and carefully put his hand on the handle of the stone door.

Both arms were lifted upwards suddenly, but Shimen did not move at all.

He couldn't help but grip it tighter and harder.

However, even though he mobilized all the strength in his body, Shimen was still tightly clasped to the ground without moving at all.

Lin Tian frowned as he looked at his palms that were already red from exerting too much force.

Should not be ah.

Although his strength is not particularly strong, it should be more than enough to open a stone door.

How could this stone gate remain motionless?
Could it be that the stone gate opened downwards?
With doubts in his heart, Lin Tian pushed the Shimen down forcefully.

However, Shimen remained motionless.

This stone gate may have been in disrepair for a long time, and something went wrong.

Lin Tian gradually had a guess in his heart, and couldn't help but look at the seam between the stone gate and the door frame.

The joints have long been filled with yellow sand and soil, without a single gap.

Lin Tian nodded suddenly.

The yellow sand filled the gap between the door frame and the stone gate, and the stone gate had no room to move, so it was naturally impossible for him to lift it.

Taking out the shovel from the warehouse, Lin Tian tentatively inserted the shovel towards the gap between the stone door and the door frame.

I want to use this to clean out the yellow sand stuffed in the door frame.

But the gap in the stone gate is straight and narrow, while the shovel is curved.

Can't fit in at all.

I can only think of other ways!

Putting the shovel back into the warehouse, Lin Tian sighed and opened the trading menu.

He was going to trade some fresh water, and use fresh water to moisten the gap between the door frame and the stone gate, and wash away all the yellow sand and mud in it.

However, after thinking for a while, he still gave up the deal.

Not to mention whether others have fresh water to trade with him.

The only fresh water in his warehouse that can be traded quickly is spiritual water, and in order to control the price of spiritual water, he needs to control the shipment of spiritual water.

Convincing other survivors that psychic water is very difficult to obtain.

Shaking his head, he took some spiritual energy water from the warehouse, tilted the mouth of the bottle containing the spiritual energy water, and poured it towards the crack of the door.

After the yellow sand and dust came into contact with the spiritual water, they instantly became moist and began to slowly seep downward.

Sure enough!

Seeing the changes in the dust and yellow sand, Lin Tian was pleasantly surprised, and at the same time speeded up his movements.

It wasn't until he spent 1000ml of spiritual energy water that he cleaned up all the dust between the door frame and the stone door.
