Doomsday: Unlimited upgrades to the shelter

Chapter 14 Drilling holes, laying pipes, opening canals for drainage (for collection)
Xie Yannan put his hands on Xiaoxiao's shoulders, "I must always take you by my side."

It's not that he wants to use her to save himself, she is too simple, she doesn't understand the dangers of the human heart, and she is easily hurt by others casually.Fortunately, Xiaoxiao is a very well-behaved little girl, and she always listens to Xie Yannan's words.

Since Xie Yannan was promoted to a second-level human being, he felt more courageous. He still let Xiaoxiao walk side by side with him. While walking, he looked around to see if there was any latest situation.

After all, after upgrading, I haven't practiced with that damn thing yet, so if I can get a few pairs, exercise my muscles and bones, and earn a little points by the way, it's okay.

The road was fairly smooth, and Xie Yannan led Xiaoxiao to the side of the creek very quickly. The distance between Lipen Valley and Lipen Valley of the creek was about 500 meters as the blacksmith Wang Hui said, but in fact it should be less than 500 meters.

The straight-line distance should be about 200 meters, but because of the visual error caused by the two raised hills, the distance goes uphill for a while and downhill for a while, making the distance longer unintentionally.

The creek was very long, Xie Yannan tiptoed to the left and right to look around, but he couldn't see the end.

About two meters wide, the stream looks very clear, and occasionally you can see a few small fish swimming in it.It also indirectly shows that there is no problem with drinking the stream water itself.

[The system has turned on the smart mode]

[Stream: length unknown]

【Clarity: 40%】

【Can purify drinking water source】

Why!The water source is available, but how to safely use the water source in the valley is still a big problem.

Xie Yannan studied architecture and was familiar with building houses and digging foundations, but he was an outsider when it came to digging canals and drainage.

He took advantage of the opportunity to pull Xiaoxiao to sit by the stream, feeling a little distressed, he didn't know the limits of the system, and whether it could directly lead to success.

If water pipes are laid for drainage, these two steep hills will directly waste water pipes, and at least 500 meters of pipes will be used for a distance of 800 meters.Moreover, the elusive zombies will also cause damage to the laid pipelines.

So?

What if the pipeline is laid through a cave instead of on the ground, similar to a tunnel?Not only can the length of the pipeline be saved to the greatest extent, about 200 meters, the water source can be diverted into the basin valley, but also the pipeline can be hidden and protected.

[The system has turned on the smart mode]

[Enable distance calculation mode]

[The distance is out of range (≥100 meters), unable to measure, please calculate manually]

It's meow!What is the use of this broken system? !Going back to the critical moment when the chain is dropped, it is impossible to measure the distance 100 meters away, which means that if you use the system to measure and calculate, you have to do it at least twice.

"Xiao Nizi, just wait here. I'll go and be back." Less than 250 meters away, he ran over in less than half a second, taking a little girl with him, which is troublesome.

"Hmm." Xiaoxiao's big watery eyes kept looking at Xie Yannan with admiration.

Xie Yannan quickly ran to the small valley between the two hillsides.Because he was on the back side of the valley, he couldn't see Xiaoxiao directly, so he could only listen to Xiaoxiao's movements distractedly, worried about her safety, and started the measurement.

【Start distance calculation mode】

【Mode: Straight line distance】

[98 meters from the inner side of the valley, 95 meters from the creek]

That is to say, the distance from the creek to the inner side of the valley is only 193 meters, even if the loss of the pipeline is included, it will not exceed 200 meters.Xie Yannan had made up his mind at this moment, so he walked through the pipeline from the ground.

[The system has turned on the smart mode]

【Engineering Mode】

【Underground excavation and pipeline laying】

[The required pipeline is 198 meters, and the engineering quantity is 10]

[System consumption points: 20 points/m*198m, 10*150]

[The system points have been updated, and the total points are now 2190 points]

I lost it!

In just a few hours, more than 1 points will be wiped out.Not a day has passed.

Xie Yannan suddenly panicked.Just now I felt a little flustered, only to hear Xiaoxiao yell.

"Ah~" There was more surprise than fear in this voice.

"Xiaoxiao." Xie Yannan ran back, "Xiaoxiao... Xiaoxiao..."

Right in front of Xiaoxiao is Sister Xu and her zombie son.

Sister Xu used a stick to block the little zombie at the other end of the stick.The little zombie drooped its head, raised its hands horizontally, and kept scratching and dancing against the air in front of its chest, and its feet kept moving forward restlessly.

But because Sister Xu's strength is relatively strong, and the little zombie's waist is tied to a wooden stick, he can't leave at all. The only thing is that wherever Sister Xu is, the little zombie will follow.

"Sister Xu, why did you come out?" Xie Yannan caught a glimpse of Sister Xu's complexion, and realized that something was wrong.

"I was kicked out by them, saying that my son is a time bomb if he stays there, how can I let him wander outside alone, in case he is burned to death by humans..." Sister Xu said, "Oh Beep" cried.

She put down her sleeves and wiped the tears from the corners of her eyes with them.Only then did Xie Yannan realize that Sister Xu's arm was injured.

Intuitively, it should have been bitten by a zombie. The tooth marks were neither deep nor shallow. A piece of flesh was torn off, and some black secretions remained in the flesh.

"You..." Xie Yannan couldn't help but heightened his vigilance, pulled Xiaoxiao back a few steps, and separated a safe distance of five or six meters from Sister Xu.

However, sister Xu's consciousness seems to be relatively clear, she should have been bitten not long ago, Xie Yannan analyzed that it is very likely that she was bitten when transferring the little zombie.

A mother who desperately protects her child never expected to be bitten back by her unconscious son.

"I'm going to die, can you please help me take care of my child?" Sister Xu plopped down on her knees in front of Xiaoxiao, tears streaming down her cheeks.It doesn't matter if she dies, the key is that she is worried about her children.

How can it be? !Xie Yannan shook his head, and refused without hesitation. Even if his sympathy overflowed, he wouldn't be able to keep a zombie by his side.

This thing is more dangerous than a time bomb. It can bite your own mother. How old are these irrelevant humans?

Although it wasn't his fault, strictly speaking, he was dead and not a human being at all.At the beginning, he didn't understand why Sister Xu insisted on keeping the little zombie, but now she paid for it herself.

Xiaoxiao didn't say anything, after all, she had said before that everything was under Xie Yannan's command.And her emotional intelligence is not low, knowing that this kind of thing is absolutely impossible, she can't ignore the danger of the people around her, right? !

Seeing that Xie Yannan and Xiaoxiao refused without hesitation, Sister Xu suddenly smiled bitterly, then turned back to the other end of the stick, and let go of the chain that held the little zombie.
