The upstream started along the dam, where the ice gradually turned into water and spread into the distance, until about the middle of the reservoir, when Xue Bin called it to a halt, and they all stopped at the same time.

"Wow...... You're exaggerating. ”

Xue Bin stood in the middle of the dam and exclaimed as he looked at the half of the water and half the ice in the upstream reservoir.

Since the water near the upstream dam has completely melted, the water flows through the dam to the downstream without hindrance, and the torrent that erupts from the flood gate falls on the ice downstream and then flows into the distance.

"How are we doing?" Tao Zi turned on the walkie-talkie.

Xue Bin praised sincerely: "Naturally, it is very good, it saves a lot of time than I expected, and I think we will be able to go back soon." ”

When they heard that they could go back, everyone cheered.

Even though they only came here yesterday morning, so much had happened in between, and it always gave them the illusion that they had been here for a long time.

However, no one expected that they would complete the task in only two days, and they had planned to stay here for three or five days.

In fact, everyone also knows that largely thanks to Su Ruan Ruan and Fei Yang, the two of them alone wiped out the zombies in a factory, and at the same time killed a super third-grade mutant snake.

What's even more incredible is that their casualties are very small, except for the two followers who died in Zhu Tao, almost no one was injured.

Xue Bin felt that if they went back to submit the mission today, the military high-level would definitely not believe it, and I was afraid that they would think that they had escaped from the battle.

Fortunately, everyone has a recorder, and I believe that those people in the upper echelons will be shocked after seeing it.

After everyone stopped, there was no continuous hot wind impact, and the water surface began to freeze again from far to near in such a cold temperature.

"Huh? The water is starting to freeze again! Won't we be in vain when we're gone? Yu Hao shouted in surprise.

Xue Bin patted him on the shoulder and said, "It's okay, it's just normal." He picked up the walkie-talkie again and said, "Everyone, don't worry about the ice, let's clean up the impurities near the dam first." ”

After receiving new instructions, the crowd began to salvage debris with various tools.

Fei Yang froze the impurities and water on the side of the rotten sash into ice, and then used object manipulation to raise it, and Tao Zi fired another fireball, directly burning this large lump of impurities mixed with ice into ashes, falling into the water and being washed away.

With Feiyang's demonstration, everyone followed suit, and the ice and fire abilities cooperated, which was much more efficient, and there was no need to think about where to throw the impurities.

In a few moments, they were almost free of impurities floating near the dam. Then Fei Yang struck again, using ice energy, to freeze the water on the edge of the dam again, and the ice surface made by Fei Yang was connected.

"Are you ready?" Su Ruan Ruan looked at Fei Yangdao who was standing on her right hand side over the walkie-talkie.

"You can go at any time." Fei Yang also looked over and looked at her, although the two were so far apart, they seemed to be close at hand.

Su Ruan Ruan chuckled, "Then let's go, don't be unable to keep up with me." ”

"No, it won't."

"Then let's go!" Saying that, Su Ruan Ruan flew directly down from the dam and landed on the ice that had just been made.

On the other side, Fei Yang had already jumped down, and the two stood on the ice and looked at each other, Fei Yang released ice energy that spread from under their feet to all directions.

"What are they doing?" Yu Hao was a little confused, "Didn't we melt the ice?" Why do you want to freeze again? ”

Xue Bin explained: "We opened the river to ensure that the water flow can pass through the dam smoothly, but the temperature is so low, after we leave, the water surface here will inevitably freeze again, although the generator work will also produce heat, but in order to avoid attracting zombies to break into the dam again, my colleagues and I have redistributed the generator sets, take turns to generate electricity, leaving only three generators to work, and the rest remain shut down, these three generators are distributed far away, but also to reduce the generation of heat." ”

"Previously, at my suggestion, Captain Fei added several layers of iron fences to the diversion tunnel to prevent zombies from entering, and shrouded the generator to prevent the heat from escaping and attracting zombies. And the purpose of this is to add a uniform ice sheet to the water surface, which is used to block the cold air from the outside and prevent the ice from being frozen thicker, and the water under the ice sheet is still flowing freely, and even if we are gone, the dam can still operate normally. ”

Yu Hao understood, he nodded and said, "So that's the case, it's really thoughtful." ”

"I'm sorry I didn't tell you, because they're the only ones who can do it, and I'll only tell the two of them alone."

Tao Zi said: "It doesn't matter, as long as you can complete the task." ”

Xue Bin smiled again: "Actually, they have other tasks, you see." ”

The two people standing on the ice, they used the ice energy while walking towards the center of the reservoir, and the ice made by Feiyang was all closely connected.

But when they reached a distance of about ten meters from the dam, the two of them crouched down synchronously, put their hands on the ice, and did not know what they were doing.

Suddenly, on the flat ice in front of them, icicles grew one after another, at the same distance from each other, neatly lined up, and then, in the presence of everyone, the icicles grew to a certain height, and then began to bulge at the side lengths, began to grow horizontally, and finally connected to each other, like a fence.

"What's that?" Yu Hao was surprised.

Xue Bin explained: "It's an ice fence, in fact, there is also a fence under the water, mainly used to keep out debris and zombies, just for temporary use, and after surviving this winter, the base will send people to build a stronger fence." ”

Once a fence was built, the two began to walk forward again, building an ice fence in the water for each distance they walked until it connected to the ice in the center of the reservoir.

Fortunately, there were no zombies attacking them during their work, and it went very well.

When Su Ruan Ruan stood on the river, he was not unaware of the mutant fish at the bottom of the water, but the number was very small and negligible.

An hour later, the two were back at the dam.

The group went back to the dam and carefully checked the inside and out again to make sure that nothing else was going on, and then they could finally go back.

Originally, Xue Bin also proposed to take a rest here, but everyone said that they would leave immediately and rest on the helicopter.

So everyone quickly boarded the helicopter, and the captain was also very excited, and after maneuvering the helicopter over the dam for a few laps, he set off towards the direction of the base.
