A female utopia under the apocalypse of natural disasters

"Sister, are those two people...?" Wang Xiang asked in a low voice.

The industrial mask covering her face affected the volume of her speech. If she answered, not only Wang Xiang could hear it, but also the two players not far away. It would be embarrassing, so Ye Ting just nodded.

"Well, let's go inside the cave and see if there are any other vents." Zhang Xue walked over, but didn't get close.

"Okay, please excuse me." A polite but distant voice came out from the mask.

Zhang Xue and Yang Qiannan said no, and walked into the dark cave with flashlights. After a while, they disappeared on the downward stairs.

Looking away, Ye Ting continued to reinforce the entrance of the cave, while Wang Xiang squatted on the other side of the cave and skillfully applied cement to the bricks.

While building, he observed Ye Ting and asked her from time to time if the side she was building was up to standard.

One person asked and the other nodded, showing some tacit understanding.

Ye Ting's plan was to build a circle of bricks around the entrance of the hole, except where the sealed jar was, to form a regular square, and then use cement and short bricks to build bulletproof glass in the square.

This is the second layer of protection.

After the bulletproof glass is installed, another layer of pure brick wall will have to be built, and a few small windows will be left on the brick wall.

Of course, the remaining windows will be covered with glass and covered with cloth.

This way, you can block outside prying eyes while retaining the ability to observe the outside world from the inside.

When building the wall, the concentration of volcanic ash and haze outside was also increasing. Ye Ting and Wang Xiang had already hung or placed three or four lights around them for lighting.

When Ye Ting and Wang Xiang almost completed the construction and only needed to seal the tank, Zhang Xue and Yang Qiannan also inspected the inside of the cave and returned to the entrance of the cave with flashlights.

After exchanging names, Ye Ting was stunned for a moment when Yang Qiannan introduced her name, but said nothing. She just stood by the cave entrance and listened quietly to Zhang Xue and Yang Qiannan talking about the results of their inspections in the cave.

The good news is that the space inside the cave is not very large. Perhaps it is for this reason that the managers of the scenic spot did not dig vents inside the cave.

In addition, the interior of the cave is still a two-story structure.

Go down the artificially excavated stone ladder and turn another corner to reach the first level of the cave. The internal space of the cave on the first level is a whole and relatively dry. There are no plants growing on the surrounding stone walls.

The lower floor is slightly smaller and does not have a larger space. It is basically a winding passage.

The two spent some time exploring all the passages on the second floor. They either became narrower and narrower until they could not pass even if they turned sideways, or they were connected to other passages, like a maze.

There is a passage that goes all the way down. In the innermost part is a small pool as big as your head, with a circle of moss growing around it and stalactites directly above the pool.

But there was no obvious water source in the pool. The two tried to scoop out some of the water with a spoon, and then waited for a while. The water in the pool did not increase, as if it was just a pool of stagnant water.

Of course, it is also possible that the earthquake has blocked the water source, so that the water in this small pool will not increase.

However, no matter what the reason is, this water is not drinkable. Who knows how long this water has been here and how many bacteria it has grown.

Hearing this, Ye Ting suddenly became curious about the pollution value of that pool.

However, it would be better to block the passages that become narrower as you go inward and have no end in sight with cement bricks as soon as possible.

Although Zhang Xue and Yang Qiannan both said that they did not smell the smell of sulfur during the caving process, before they knew what was deep in the cracks and where they led to, they sealed the passage first, even if it was dangerous. There is no threat to them.

Only one person could fix the vent at the entrance of the cave, so Ye Ting stuffed Wang Xiang and Yang Qiannan with a few tools each, more than a dozen red bricks and a small bucket of prepared cement mortar, and sent them directly to seal the passage. .

She stayed here quietly by herself, carefully working on the only vent.

First, surround the left and right sides of the sealed jar with square double-layer insulated glass. Take out two pieces of ordinary glass and use a glass knife to cut out two equal-sized circles on the left and right.

Paste two pairs of gloves with cement between two layers of ordinary glass circles. One layer is anti-scalding and heat-insulating, and one layer is rubber to prevent external volcanic ash from entering the cave through the gaps in the gloves.

Before sealing the glass with gloves, Ye Ting summoned her guardian panel to scan the volcanic ash pollution value in the sealed jar.

The pollution level of volcanic ash reaches 3.7, and the environmental nuclear energy level currently shows 3, while the pollution level in the cave is only 2.5, and the geonuclear energy level is consistent with the pollution level.

Her own pollution value has also reached a high of 11%.

It makes sense when you think about it. She has left the safe and extremely low-pollution indoors since the earthquake. Even though she has been wearing a mask and protective clothing all the way here, there are always things she doesn't notice.

However, the 11% pollution value did not bring her any special feelings, and there was no uncomfortable part on her body.

She speculated that it may be necessary to reach a certain critical point of pollution value before any changes will occur.

After writing down the scanned data in her notebook, Ye Ting closed the thermometer probe into the space where the sealed jar was.

The wire connected to the probe passes through the gap between the glass plates. A thermometer can be plugged in at any time and the probe can be used to measure the temperature of the sealed tank and the outside air.

She planned to wait and see first to see how high the outside temperature would rise and how long it would take for it to drop.

The gaps between the glass plates were filled with cement to try to prevent volcanic ash from entering the cave.

After surrounding the sealed jar with glass plates on all sides, Ye Ting took out the high-temperature air filter cotton she bought in the real world, cut it into a suitable size and covered it.

Seal the surrounding area with cement, build a circle of insulating glass strips about five centimeters high, and then cover it with filter cotton.

With a layer of filter cotton and a layer of insulating glass strips, it took five layers to make Ye Ting feel satisfied.

If the temperature cannot be lowered in a short time, she will open the lid of the sealed tank to let the air in through the filter cotton. If the concentration of volcanic ash outside is too high, she can also build several more filters and insulating glass. strips, and place a few air purifiers around the vents to filter the air.

She couldn't believe that under such heavy protection, she could still be killed by volcanic ash.

With the last layer of glass strips sealed, the multi-story chimney is almost complete, but it will have to wait until the cement is completely dry before it can be put into use.
