Doomsday: Unlimited upgrades to the shelter

Chapter 122 Discovering the City Under the Lake

But Xie Yannan was immersed in the joy of a child, and kept sliding back and forth, coupled with the sound of her feet rubbing against the ice, she didn't notice the abnormality Xiaoxiao said at all, and didn't even hear her call Voice.

"elder brother……"

Xiaoxiao was a little anxious there, and her strong sense of safety told her not to take another step forward, but seeing Xie Yannan walking forward without any sense of defense, she couldn't help but take a few steps forward.

Since Xiaoxiao upgraded this time, her weight is obviously 2 or 3 times that of before.Just as I was stepping forward, I only heard two clicks, and the ice cracked.

The crack quickly crawled along the ice to where Xie Yannan was standing, and the crack became bigger and bigger.

At this moment, Xie Yannan happened to be in the middle of the entire lake, he heard the abnormal sound under his feet, and saw the cracked ice surface, so he quickly lay down on the ice surface, crawling forward with the whole body, trying to reach the ice shore as soon as possible.

Xiaoxiao also made the same movement, lying down gently on the ground.Because of its heavy weight and too much strength, Xiaoxiao smashed a hole in the ice the moment she lay down, and Xiaoxiao fell into the water.

"Xiaoxiao, Xiaoxiao..." Xie Yannan propped forward with both hands, switching palms for a while, switching elbows for a while, trying to get closer to Xiaoxiao quickly.

But after Xiaoxiao fell into the icy water, she didn't say a word, and her whole body sank until she couldn't see clearly...

"Xiaoxiao, Xiaoxiao..." When Xie Yannan reached the ice hole where Xiaoxiao fell, new ice condensed on the surface of the ice hole. Ordinary lake water can condense new ice at such a fast speed that Xie Yannan I feel a little incredible.

What's even more incredible is that the Xiaoxiao robot, which is said to be so powerful, has never opened its eyes since it fell, and it keeps falling deeper. Xie Yannan can only see her getting farther and farther in front of him.

It is quite unscientific to reach out and clench your fist to hit the ice surface, even if you try your best, you will find that the ice surface does not respond!
Xie Yannan suddenly saw that there is indeed a shark-like creature in this lake, it doesn't just look like it, after all, how could there be such a thing in a lake deep in the mountains and old forests, it should be something else, just because I can't see clearly , cannot be fully identified.

He thought for a while, took the ax from the system, and managed to make a small opening with great effort.

The ice here is not right, how could it be harder than a steel axe.

Xie Yannan glanced at the axe, the tip of the axe had been knocked out several times, which made him feel strange.

The ax was useless, but Xie Yannan suddenly remembered that salt could melt ice.

Because the main component of water is water, and the main component of salt is sodium chloride, sodium chloride is a substance that is easily soluble in water, and the sodium chloride aqueous solution formed after sodium chloride is dissolved in water contains chloride ions and Sodium ions.

When freezing, as long as chloride ions and sodium ions exist at the same time, chloride ions and sodium ions will destroy the crystal network structure of water, so that water cannot freeze.Even if the water is already frozen, sodium chloride will seep into the ice to form saturated brine, which will slowly melt the ice.

When Xie Yannan originally took the items out to the storage room for storage, he kept some things he thought were useful. Of course, there was a bag of salt in it now, and he took out the salt without hesitation.

Then the secret was sprinkled numbly on the small opening that had just been made, and then he breathed a sigh of relief with his two palms and began to break open the ice cubes with his bare hands.

Xiaoxiao seemed to be sinking, and she couldn't see her.Xie Yannan became more and more worried about her getting up, but he didn't expect that there was such a deep lake in this mountain.

This ice is very cold, much cooler than the ice cubes Xie Yannan made in the refrigerator before, and it doesn't look like ordinary ice.

He couldn't help being so cold that he sneezed several times, but he couldn't stop to think about other things.

The ice was softened by the melting of the salt, Xie Yannan seemed to be effortlessly breaking off the ice, and after a while he broke off a large piece, which seemed to be enough for Xie Yannan to jump into the lake.

Now a new problem arises, he can easily jump into the lake, but the ice will definitely freeze as before, then both he and Xiaoxiao will be sealed at the bottom of the lake.

Thinking of this, he shook the plastic bag that hit the salt, and then drew a circle with a diameter of about half a meter on the ground. It must be done quickly, the salt melted extremely fast, and the ice was extremely hard. Xie Yannan Without any hesitation, he didn't even bother to take off his clothes, and jumped directly into the icy lake.

It was as if he had fallen into a huge ice cave. The degree of coldness was completely beyond Xie Yannan's imagination, and he couldn't help but shiver several times.

Fortunately, the water in the lake was still, so Xie Yannan jumped headlong towards Xiaoxiao's falling direction based on his memory.

Even in such a cold day, there are still many strange creatures in this lake, those goldfish that look like the size of a puppy, and some plants that are obviously aquatic plants have sawtooth on both sides.

And the shark-like thing I saw just now, it is indeed a shark or an ordinary fish, but I don’t know why it looks like a human being, and after being magnified by the ice layer on the lake, it looks like a fish from above. It looks even bigger.

What the hell is this place? !

Xie Yannan managed to grab Xiaoxiao's arm, but her legs were entangled by water plants, no matter how hard she kicked her legs, she couldn't get rid of the entanglement of water plants.

He could only take Xiaoxiao to swim to the end of this aquatic plant, but discovered a bigger secret.

The aquatic plants grew from the side of a large door. The average aquatic plants were only three or four meters long, but this length was obviously more than ten meters long, which looked extremely distorted and mutated.

The strange thing is that there is a big door here.

After staying under the water for a long time, Xie Yannan obviously felt that it was difficult to breathe, even though he was a 2+ level human being.He can only speed up.

Fortunately, the sun is still relatively bright today, and the light is strong. It shines on the bottom of the water, and everything can basically be seen clearly.

He looked closer to the door, and pushed the door lightly with his hand, but the door couldn't be opened at all, and the pressure of the water made the force seem even stronger.

The door is bare, it looks like it is made of metal, and it seems to have been under the water for many years, and the seaweed at the corner of the door tightly entangles the door around it.

Suddenly, Xie Yannan found that there seemed to be a shallow mark on the door, which was a deformed skull.Xie Yannan was familiar with this mark, it was a sign of radiation.

Could it be to warn people outside that there are materials with strong radiation inside?
