Doomsday: My Shelter Unlimited Upgrades

Lin Tian didn't pay too much attention to Shimen's introduction, and couldn't wait to put his attention on the strengthening list.

"Enhancement Branch 1: Material Enhancement: Upgrade the material of the stone gate to alloy, the firmness of the gate will be greatly improved, the defense effect will be greatly improved, and the corrosion resistance will be greatly improved."

"Enhancement branch 2: function enhancement: strengthen the thickness of the stone gate and the density of the stone, slightly increase the firmness of the stone gate, slightly increase the defense effect, and greatly increase the weight of the stone gate."

He decisively ignored the reinforcement branch 2, and clicked on the evolution branch 1 to check the materials needed for reinforcement.

“强化分支1所需材料：铁矿*100单位、铜矿*10单位、锡矿*15单位、镍矿*5单位。求生点数*50。”

After seeing the materials needed for the alloy gate, he was overjoyed.

Fortunately, with the accumulation of selling kitchen utensils before, he has a lot of iron ore in his warehouse.

The last time I sold the blind box of the treasure chest, I also made a lot of money. Although there are not many copper ore and tin mines, it is enough to strengthen the gate.

strengthen!

Lin Tian gently touched the stone gate with his right hand, and muttered in his heart.

With his voice, the corresponding materials in the warehouse were instantly deducted, and 50 survival points were also subtracted, leaving 330 points.

He set his sights on the stone gate.

Under the strengthening of the system, Shimen emitted bursts of white light, surging and changing its shape like a melting jelly.

Ten seconds later, the surge stopped, and the white light gradually dimmed.

He looked towards the evolved gate, and then marveled.

Leaving aside the inside of the gate, the change in appearance alone is astonishing!

The first is the most intuitive size.

The current gate is more than double the size of the previous Shimen!
Not to mention that Dabai can pass easily, even if there is another creature twice as big as Dabai, it can pass easily.

Of course, the benefits of an enlarged door are obvious.

Can pass through larger objects and more.

But the disadvantages are more obvious and fatal!

That is, in the chaotic apocalypse, a bigger door means a bigger goal!
Shelters are more easily exposed to enemies!

In fact, after Lin Tian had the idea of ​​expanding the gate, he had such worries.

That's why he didn't upgrade Shimen for a long time.

However, after Dabai joined the refuge, the original stone gate was obviously not enough.

You can't force Dabai to squeeze in every day, can you?

Not to mention how uncomfortable it is for Dabai to squeeze in like this all the time, whether it will smash the door.

If one day, Dabai has a better appetite and eats more food.

Then it can't go through the gate?
In order to avoid such a situation from happening, he had to choose to upgrade.

However, looking at the upgraded gate, his worry that the gate would expose the shelter disappeared.

Because the finished alloy gate is not as shiny and metallic as ordinary metal gates.

The system thoughtfully painted a layer of yellow camouflage on the gate.

The color of this layer of camouflage is exactly the same as the color of the landmarks near Shimen, and the pattern is also very realistic.

If it weren't for the fact that the gate was above his head, and it felt hard and extremely cold to the touch.

He was afraid that he would really think that the land in front of him was ordinary land, not the alloy gate!
Lin Tian checked the alloy gate from the inside, and after finding that there was no problem, he was ready to go out and check it.

Putting his hands on the stone door, he put on a posture that would use all the strength in his body.

The unstrengthened stone gate was very heavy, requiring him to use a lot of strength to push it open.

After strengthening, the volume of the alloy gate is more than double that of the previous gate, and the weight is definitely much larger than before.

Hope it's not too heavy.

Lin Tian took a deep breath, mobilized all the strength in his body, and pushed his hands outward heavily.

However, something unexpected happened to him!

The weight of the alloy gate is not as heavy as he imagined!
On the contrary, this seemingly huge alloy gate is actually lighter than the Shimen before it evolved!
But at this moment, he has already mobilized all the strength in his body, pushing out with all his strength, and it is too late to retract his strength.

boom!
With a loud noise, the alloy door opened instantly and hit the ground with a loud noise.

Lin Tian himself also shook himself because he didn't estimate his strength well, and almost fell down.

Stabilizing his body, he took a breath and quickly climbed out of the shelter.

He really didn't expect that the alloy gate was so light.

If I use so much force, I won't break the alloy gate, right?

This has just been strengthened, if it is broken at this moment, he will cry without tears!
Climbing out of the shelter, he quickly turned the door over and closed it again, looking at the exposed side.

Then, his tense heart finally let go.

The alloy gate has not been damaged in any way, not even a trace of trace is left on it, it is as brand new as when it was just manufactured.

The outside of the gate is also painted in camouflage, and it looks more refined than the inside.

Realistic!

If he didn't know the location of his shelter, he was really afraid that he wouldn't be able to find his way back to the shelter after he went out.
