Doomsday: Unlimited upgrades to the shelter

Chapter 242 Disappearing
After all the weapons and equipment were moved onto the flying motorcycle, there were only some scattered parts on the ground in the entire shelter, which Ma Wu had disassembled and couldn't use.

"You send Uncle Ma home first, the flying motorcycle can't hold so many people, you can come back and pick me up later."

Of course Xie Yannan understood that as a hero, Ma Wu could not be slacked off.

"Yeah." Shiliu nodded and left with Ma Wu.

After everyone returned to the refuge, everyone made a preliminary planning and design.

It is intended to use the existing weapons as much as possible in the current defense.

The six tanks were distributed in the six corners of the shelter according to the original plan, and their movable range was set. Within one kilometer around the center of itself, it basically completely covered the one kilometer around the center of the shelter.

In this way, because the high-foot heat-sensitive tanks are designed for long-range, they will automatically identify the enemy within five kilometers through infrared rays and launch an attack.

The ten reconnaissance planes don't have to be put into use yet, four are activated using meteorites, and they are located in the four directions of the shelter.

The blackbird stealth reconnaissance plane was placed in the vertical sky above the refuge. After all, the tall tanks have a long range. In case a fish that slipped through the net approached, Xie Yannan could also take precautions in time after the reconnaissance plane issued an alarm.

In addition, there were more than 20 missiles. Xie Yannan pretended that eight of them were at the top of the shelter. As long as the reconnaissance plane issued an early warning, the nearest missile would be automatically activated to attack the intruders.

Of course, in order to avoid accidental injury, Xie Yannan also specially set up a withdrawal mechanism, and the authority lies with Xie Yannan himself.

As long as the missile is still changing its path and has not hit the enemy, it may be withdrawn by Xie Yannan.

Xie Yannan stored the remaining missiles and reconnaissance aircraft on the second underground floor.

Bullets and pistols are directly put into the system for easy access and use at any time.

After deploying all this, three days have passed.

Xie Yannan conveniently checked the points.

[The system has automatically turned on the smart mode]

【Services】

【Points Query】

【Currently has 35000 points】

The main purpose of the points now is that Xie Yannan wants to save them to exchange for reputation points and upgrade to a fifth-level human as soon as possible. I don’t know if a fifth-level human has any other abilities, but it takes twice as much to go from a fourth-level human to a fifth-level human. The reputation value seems to be a bit far away at the moment.

……

Waking up early in the morning, Xie Yannan planned to take Shiliu and Xiaoxiao to Yunxia Mountain again.

Back on the ground, I saw Qin Xiaocheng squatting there with a sad face.

"Xiao Cheng, what's wrong with you?"

"It hasn't rained for three days. Although our shelter is equipped with an automatic water circulation system, after all, the water for the cycle of grains and the evaporated water also need rainwater to subsidize it. If this continues, our shelter will easily run out of water. gone."

He frowned and said, "With the current water consumption, if it doesn't rain, the water in the shelter will probably last for a week at most."

Xie Yannan has been busy with the weapons during this time, so he didn't notice at all that it really hasn't rained for a long time.People can go a day without eating, but they cannot go a day without drinking water. This is still a big problem.

"It seems that there are no other water sources around us, right?"

Xie Yannan remembered that he used water from a small stream before, but because the stream was polluted by zombie viruses and he had recirculated the water, he didn't use it anymore.

"No, the rest of the water sources are far away, at least ten kilometers away, and it is impossible to call them."

Qin Xiaocheng said slowly.

"Ten kilometers? Isn't that about the same distance as the lake in Fanshan Mountain?"

However, Xie Yannan had no intention of dealing with water at the moment. He had already arranged to go to Yunxia Mountain to get a feel for it, and Wei Beiming had already prepared a nano protective mask for him yesterday.

The nano protective mask can isolate everything from the outside world, including the air.

But in this way, Xie Yannan might have difficulty breathing again, so he installed a nano oxygen generator.

The mask is only as thick as a mask, but it can cover the entire face, but the eye area is made of transparent material, so that it will not affect Xie Yannan's vision.

The nano-oxygen generators are located on the two sides of the mask, next to the ears, but because they are shrunken air compressors, they are basically invisible.

"This oxygen is enough for you to use for 24 hours."

When Wei Beiming handed the mask to Xie Yannan's hand, he gave special instructions.

"We have to gather at the bottom of the mountain and come back no matter what happens in one day."

Xie Yannan also instructed Shiliu and Xiaoxiao.

When entering the mountain this time, Xie Yannan was obviously much more confident because the system had stocked a lot of weapons and protective tools such as masks.

He took the lead and walked tentatively in front. It seemed that he saw some Zerg species along the way, but no other strange creatures.

It's just that the Zerg seems to be more boring than before, mechanized digging, weeding, fertilizing, and logging...

It was as if everything else around me didn't exist.

Xie Yannan was originally talking to Shiliu while walking all the way.Later, when I was walking, I saw some strange jagged plants, a bit like the ones seen on the bottom of the sea.

He tiptoed over and planned to turn around and ask Sixteen if this plant really had radiation.

When he turned around, he realized that Xiaoxiao and Shiliu were gone.

Because before going up the mountain, Xie Yannan also said that in order to extend the use time of oxygen, everyone should not move too much.Xiaoxiao and Shiliuben followed him very lightly.

So Xie Yannan didn't even realize when these two guys disappeared.

This time, he didn't care about the plants in front of him.

"Xiaoxiao, sixteen..."

He planned to go back the way he came, and after taking two steps, he found that Xiaoxiao and Shiliu's footprints disappeared here.

The very special footprints of the two people suddenly disappeared within a range of less than 30 meters from him, which means that they must not have the ability to disappear out of thin air like this, and they may have encountered some accident.

Xie Yannan forced himself to calm down, thought about it, and remembered that Shiliu once said that this mountain is full of surveillance, that is to say, from the moment they entered the mountain, the other party knew about it, but they didn't take any action.

but……

Xie Yannan raised his head, searched for a surveillance camera casually, and raised his middle finger at the surveillance surveillance, "Don't touch my friend."

After waiting for a few minutes, there was no response from the other party. Xie Yannan thought the monitor was broken and planned to change positions.

Suddenly, a voice came from inside...
