”The price is not expensive, but the material of the door of the refuge is completely sufficient, there is no need to spend it on this.”

shook his head, Somo concentrated, calling for another way of transformation.

【Refuge Shimen】

Description: The gate is made of solid stone. After the pry is put down, it is indestructible and safe.

Upgrade: material (180), shape (60), size (35-600), independent function (20-600)...Iron roulette code lock (70)...

”Good! What I want is this kind of mechanical opening and closing combination lock, which is highly practical and not easy to cause problems!”

Sumo applauded and sighed, his face full of satisfaction.

Compared with the end times, especially for this kind of gate, the older the mechanical type, the more practical it is.

is rather bells and whistles, such as fingerprint password locks, key locks, etc. given by the system are not very reliable.

is still this kind of roulette-type mechanical code lock is much more reliable!

Back to the material room, Somo began to take the iron block.

Thanks to the previous acquisition, there are still dozens of units in the iron block, piled together like an iron wall.

Go back to the gate and put down four iron blocks in succession. The price of the roulette code lock is reduced to 35 and no longer changes.

said silently to upgrade.

Green light shot out, and the iron block on the ground immediately floated in the air, turning into a pool of fiery red molten iron.

Under the ingestion of the green light, the molten iron was attached to the surface of the stone, without any trace of man-made, just like a handle that was born on the stone.

Three to five seconds later, the green light recycles.

The new shelter door lock has been designed!

”The initial password is seven zeros, um...then change it to ~~ even if you want to decipher such a complicated password manually, it will not be difficult to decipher it manually.”

This kind of big roulette lock, even if a professional locksmith comes, it is difficult to decipher it in a short time.

After setting the password, pushing back the latch, and opening the door of the refuge, Somo came to the outside of the refuge.

The sun in the wasteland has not yet fully heated the morning air.

A wave of chill flows along with the wind, and wind and sand blow up on the blowing plain.

After looking around for no abnormalities in the vicinity, Somo safely closed the door and began to try the switch operation.

is closed first.

Only need to adjust the password to the correct, you can hold the roulette and turn it until the lock tongue is stuck and the roulette cannot be turned, the closing is successful.

Disrupt the code lock, the roulette cannot be turned.

After all the codes are suitable, you can twist the roulette back in the same way and unlock the bolt.

”Okay! This way you can rest assured, at least there is no need to go in and out of the back door in the future!”

Looking at his masterpiece, Somo tried to make sure there was no problem, then walked along the hill to the back door.

For this back door, Somo has his own ideas.

called out the system, aimed at the back door, and as Somo's voice fell, five survival points were deducted.

The back door that could have been opened is directly closed, and it is completely integrated with the ground, and there is no gap in it.

”This backdoor, if you need to use it, it must be when a crisis arrives. Even if it spends five more points to open it, it is also a good deal. On weekdays, it will be sealed off and used as a hole card!”

nodded, and after opening the front door and returning to the refuge, Somo began to pack the things to bring.

The ”wealth” in Refuge No. 2 is also time to harvest a wave!
