Doomsday: Unlimited upgrades to the shelter

Chapter 72 Upgrading the Laser Tunnel

"Didn't you say it was going to die?" Xie Yannan's implication was, isn't such suturing a waste of effort and energy?

"Yes." Zeng Rui didn't explain too much, insisting on sewing up the cow's belly.

"Moo~" The calf still couldn't open its eyes, it shook its body slightly and then stopped moving.

"Just put it here, the vitality of the cow is quite tenacious, and it won't die." Zeng Rui seemed to be worried, and he touched the calf's four legs, "There are no fractures or obvious injuries, so it should be fine. question."

"Thank you, grandpa." Xie Yannan picked up the cow and planned to use it as fuel.

"Yeah." Zeng Rui seemed a little lost and walked away.

Night fell in full force.

That's fine, this is the first time Xie Yannan has accumulated so many points. He has long wanted to upgrade a decent defensive door in the stairway to the basement. This is a thin wooden door that Wang Hui made before, and it may be gently knocked by the scalper. Top, it will be scrapped.

However, because of the special location and the step-by-step downward steps, it is definitely unrealistic to make the gate of Xiangpen Valley.

Suddenly, in the Avengers in the rice drama, there is an Avenger named Huanshi who can emit laser light from his eyes. When the laser light hits a tree, the tree will be broken immediately. If the laser light hits the iron plate, the iron plate will be able to was cut in half.

Or the passage from the basin valley down to the basement can be made into a laser passage? !
Then the problem comes, the ordinary laser channel will not be able to distinguish the self from the enemy, and it is easy to be burned together when entering the basement.

Xie Yannan pondered for a while, how can he make further breakthroughs in the technology of identifying friend and foe, and suddenly he thought of the loyalty of the system's latest launch...

in case……

It is a good decision to identify based on loyalty, after all, loyalty is the most intuitive feeling about whether you are loyal to yourself.

A score of [-] should be enough, then anyone below [-] will die, no matter if it is a person from Bungu or an intruder from outside.In this way, his own safety is also guaranteed, and accidental injury is also guaranteed.

Thinking of this, Xie Yannan had already made up his mind and upgraded the entrance of the basement to a laser passage.

What the hell!

Forgive me for being uneducated when I was born, and go all over the world with a single sentence!

When Xie Yannan looked back after ten minutes, the entire limestone staircase was neatly paved with floor tiles, and there were many conical inverted triangles on both sides of the wall.

This is?Is this a laser hole?There are at least a thousand of these dense protrusions on the two walls, so that large living things can't get in at all.

After all, there are nearly 20 meters from the first step to the last step. The laser burns first, and then gradually. If it is a smaller creature, it is estimated that even the bones will be melted away.

Xie Yannan touched the wall contentedly.Taking a step back, if any monsters attack, this laser channel alone will be able to defend for a long time.

When he returned to his room, he passed by Xiaoxiao's room again, and couldn't help poking his head in, "Little girl, brother strengthened the defense of the basement, sleep well, there will be no danger in the future."

Xiaoxiao's favorite thing to do now is to sit on the bed with her legs crossed in a daze. She doesn't seem to hear Xie Yannan's words, but her eyes seem a little hollow.

"Okay, just ignore me." Xie Yannan went back to her room despondently, and would go to the underground shopping mall tomorrow to purchase materials for bows and crossbows, so she must rest well tonight.

Xie Yannan fell asleep again without knowing it.Since entering the basement, sleeping has become extremely easy.

only……

It's just that after Wei Xiaofei left, Xie Yannan would dream of her almost every night, occasionally it would be some wonderful memories, and occasionally he would be awakened by nightmares.He would turn over excitedly, wipe the sweat off his body, touch the bracelet Wei Xiaofei left for him on his hand, and sigh heavily.

……

Meow, what time is it? !
Xie Yannan only felt that the sunlight scattered from the ventilation holes was dazzling, it must be almost noon, right? !
Why didn't that little girl Xiaoxiao come and tell her to get up? !It's not like her style, is it? !
He turned over and got out of bed, and then thinking that the little girl might be sleeping late, he tiptoed to her bedroom door.

But the room was empty.

Hey, strange, where will she go?Why now I am more and more like a brother.

Xie Yannan was a little nervous about returning to the ground, but saw Xiaoxiao squatting under the bottom step of the basement, clutching her arm, as if she was sobbing softly.

There are several burn marks on the arm. Although there is no bleeding, the wound is particularly conspicuous.

"Little girl, what's wrong with you." Xie Yannan also squatted down beside Xiaoxiao, stretching out his right hand to touch her wound.

"I'm fine, brother, did I go out?" She raised her hand, as if she didn't want Xie Yannan to touch her.

"Could it be that your wound was burned by a laser?" Xie Yannan immediately reacted.

This……

【Loyalty Judgment】

【Xiaoxiao: 85 points】

[Trend: will continue to decline]

Damn, what's going on, Xiaoxiao's score was always the highest before, why did it drop to 85 all of a sudden.The more Xie Yannan thought about it, the more something went wrong, and he blurted out, "Did I mistook you for Miss Fei that night?"

This is also the fact that Xie Yannan doesn't want to face the most, but he has to understand what he did to hurt Xiaoxiao after all, how could he suddenly avoid him like this, and now from the point of view of loyalty, he is disgusted.

"Brother, what are you talking about, I don't quite understand, you let me out, I'm hungry, I want to eat." Xiaoxiao's eyes kept avoiding Xie Yannan, and she didn't respond directly to her words.

"Okay, brother, I'm afraid I didn't intend to hurt you, as long as you're fine." He said so, but Xie Yannan's knot was even heavier.
