Doomsday: Unlimited upgrades to the shelter

Chapter 13 Upgrading the Outer Gate to Resist Zombies (For Collection)
The size of the bed board is 0.45 meters high and 2 meters wide, which means that the bed is actually a square. 0.45 meters is the height of the bed from the ground.

The simplest bed is to use only the rails and joists.The thickness of the plank is 0.02m, which is enough to use only parallel keels as support, without the more complicated vertical cross row keels.

With a bed width of 2 meters, if the keel is enough to support the strength of sleeping on it, it must be designed densely. The size of the keel is 2 meters * 0.2 meters, and one keel is placed at an interval of 0.3 meters, so that six keels are laid flat on it.

Xie Yannan is not stupid, he knows that he is enjoying this bed alone now.In case a woman came behind, he had to ensure that the bed could withstand the impact of his and her daily exercise.

Xie Yannan showed Su Yu the size he had planned, and asked him to hurry up and make the bed as soon as possible.

Xie Yannan designed the most original bed, so there is nothing wrong with the low score.Just use it first, and then it can be upgraded to a bed with cleaning and massage.

More important right now is the issue of water sources.

Xie Yannan walked to the gap in the basin, from where he was pushed in by Xiaoxiao, the gap was about two meters wide, and it was also the only entrance and exit of this basin.

In order to defend against zombies, Wang Hui and the others used five large trees to tie them together horizontally.It looks solid, but also very watery.

It's no problem to defend against a few junior zombies, but if more zombies come in, they will become vulnerable, completely powerless to fight back.

He originally wanted to go out of the basin valley to see if the creek could be used, but found that the wooden door needed preliminary upgrades.

This time consumed 1340 points, Xie Yannan's heart aches, but there is no way, the front must be done well, otherwise the zombies will drive straight in, and no matter how well the inner kung fu is designed, everyone will be finished.

Xiaoxiao has been standing next to Xie Yannan, staying with him quietly.

She pushed the new iron gate lightly.The axles connecting the iron gate and the rock wall are extremely smooth, and the design quality and pressure resistance are of an excellent level, which is obviously completely incomparable to a few horizontally placed trees.

There is also an automatic combination lock on the door. Although it seems a bit out of place with the surrounding environment, it can at least initially prevent those unknown people from entering.

You must know that in the last days, everyone is protecting themselves, and cannibalism often happens when they are hungry and panicked. What crazy things can't be done? !
Xie Yannan asked Xiaoxiao to write down the password, and told her to go back and tell Sister Xu and the six craftsmen.

Hey, the points are well spent.Speaking of the six craftsmen, although Xie Yannan accepted them, the system has not recorded the reputation value, I don't know why?
Xie Yannan wandered around in front of the door for several times, but still felt that there was something missing, the basic defensive ability was there.But if more than a dozen low-level zombies come crashing into the door together, the door will be broken in an instant, with only defense ability and no attack ability at all.

It's hard to protect the door itself, let alone protect them? !Meow, I feel irritable just thinking about it.

But now his points are not enough to exchange for large weapons. He lowered his head and thought for a while, if it can't be solved with heavy weapons.Then you can also do some simple hands and feet on the door.

He remembered that when he smashed the zombies with durians before, it seemed that sharp things had a strong attack power on the zombies. If some sharp protrusions were formed on the door, so that the zombies could not approach, and then pushed the door, it would be regarded as an upgrade. The role of defense.

When Xie Yannan thought of this, he already had his preliminary plan for the sharp protrusions in his mind.

The sharp raised parts are still all made of iron fingers, similar to an inverted cone. The diameter of the inverted cone is designed to be 0.05 meters, with the tip facing outward, and the bottom of the cone is integrated with the door.

There is no need to use too much on the iron gate, just a part of the irregular design of two meters from the underground net.The design is redundant and too high, fearing that some zombies will use them as fulcrums and directly climb over the door.

Fuck!This, this, this...

The processing points of the hanger on the door consume much more than the processing points of the door itself.Xie Yannan couldn't help swallowing silently, and went around to the outside of the door to see the effect.

There are fifty or sixty sharp protrusions on the secret door, and the highest position is a little higher than Xie Yannan's height, which is in line with Xie Yannan's expectation.

He lightly touched the needle-like sharp protrusion with his hand, and immediately retracted his hand reflexively. A little blood oozed from the fingertips. It seemed that this thing was really sharp.

In this way, although the zombie will try to get close without consciousness, it will also hurt itself, and the defense and attack are combined into one.Wait for the points to be enough later, and then replace it with a stronger door to increase defense against medium and heavy weapons.

"My brother is so great." Xiaoxiao looked at her with admiration. She tugged on the corner of Xie Yannan's clothes and said, "When I grow up, I want to marry my brother."

"Go, go, you little brat is joining in the fun." He tugged on Xiaoxiao's pigtails.

In Xie Yannan's eyes, she was just his sister, and he never had any inappropriate thoughts, not to mention that she was really just a little girl.

"Tsk tsk tsk, although I still have a little baby fat face, I will definitely be a beautiful woman when I grow up. As the saying goes, fat water does not flow to outsiders' fields." Xiaoxiao imitated the tone of an adult, talking nonsense solemnly.

Big guy!
"Little girl, I'm going to go out of the valley now to see if the creek over there can be used."

Xie Yannan originally wanted to ask Xiaoxiao if she would like to go out on an adventure with him, after all the zombies outside don't know what's going on.

The six horny men and one bloodthirsty woman here are probably more dangerous than outside.I just feel like I can't ask any questions.

"Where is my brother, where am I?" Xiaoxiao blinked at Xie Yannan, "I am your exclusive mobile antidote, can you not take me?"

　The conceptual hand-drawn draft of the door design was posted on the best post in the book circle. Although the drawing is a bit handicapped, but after the summer vacation, I will definitely replace it with professional drawing software. Thank you for your great support.
