Su Ruan Ruan stretched his waist and cheered up, he would almost finish his work today, and then he would be able to go back.

In the morning, after everyone washed up and had breakfast, the next step of the plan began, this time it was necessary to divide into multiple groups, and almost all of them had to be mobilized.

Everyone walked to the top of the dam first, and according to Su Ruanruan's method yesterday, the ice blocks near the diversion tunnel were removed, and the debris and zombies blocked in it were removed, and then Fei Yang repaired and strengthened the trash rack, and then he went down with the three engineers, and when the people above opened the river, they checked the condition of the equipment below, and they could repair it in time.

Xue Bin asked them to first connect the drinking water tunnels one by one, and then carry out a large-scale opening of the river after inspecting all the turbines and generators, which means melting the ice on the upstream water surface and allowing all the water to flow out through the tunnels.

However, they didn't forget that there may also be mutated aquatic creatures in this water, and they need to prevent them from sneaking up when opening the river.

Therefore, all the abilities with combat power need to come up and kill the zombies that may appear at any time.

The wind was much lighter on this day, and the sky was brighter than yesterday, just enough for them to carry out their tasks.

Peach stood above the mouth of the second tunnel, she reached out and condensed a fireball the size of a walnut above her palm, and then threw it out like yesterday, and in a few moments, the water spurted out of the hole and rushed directly into the tunnel.

Then Xue Bin's voice came from the intercom: "The second generator has been working, and the water turbine is being repaired." ”

This is undoubtedly good news, it seems that the zombies entered the dam only to escape the cold, and did not wreak havoc on the equipment inside.

Immediately after, Tao Zi used fireballs to melt out the second and third ice caves, and the turbulent water rushed into the tunnel, and after a short while, there was a noisy sound of water flowing on the downstream side of the dam.

Zhu Tao and his two followers stood on the platform above the downstream tunnel, and Xue Bin said that it was just in case the water flowed downstream and froze again, so it was necessary for the fire type to melt the ice on the river surface and around the tunnel downstream.

So Zhu Tao volunteered to go, because since he received the task to come here is basically the least contribution, although his purpose here is not pure, but always to do something practical, so as to make up for the part of the general who was a deserter halfway, and let the old man count him lightly after he goes back.

And the rest of the people are standing above the dam and ready to stand.

Taozi walked from north to south from the dam, and opened all the entrances to the diversion tunnels one by one, during which he naturally encountered zombies that spewed out with the flow of water, and were wiped out by everyone on the side.

In the factory on the right, in addition to the generator that has been completely destroyed by the zombies, six of the remaining nine are usable, and the other three have some problems and need professional maintenance, so one Feiyang alone is not enough.

Fortunately, most of them are usable, and these six high-power generators alone are completely enough to make the base use electricity normally.

In fact, the generators in the hydropower station are not all working before the end of the world, and they need to be divided into different units to alternately use, and now it is the end of the world, and the hydropower station only supplies power to the base alone, so there are fewer generators that only need to operate, so that the use of turns can also extend the service life of the hydropower station and allow the base to persist for a while longer.

And their job now is also to check the fault so that it can be eliminated in time.

The factory building on the right was almost checked, and Feiyang added an ice sheet above the current, and everyone went to the left.

It took an hour for Taozi to open up all the water flow, and after Xue Bin checked all the equipment inside the factory, he informed them through the walkie-talkie, indicating that two generators in the factory were out of order, but overall it was very good.

Fourteen generators are more than enough for the base to last a long time.

The work took a total of three hours and was completed without a hitch.

At the same time, before these works began, Feiyang also sealed the big pit in the factory on the right with metal inside and out, just in case any zombies came in through here.

After that, the river can be opened on a large scale.

But instead of doing it immediately, they all returned to the dam to rendezvous, eat and rest for a while, and then go.

Because the water level in the reservoir is very high, the water in it needs to be released for a period of time to lower the water level, otherwise the river will melt the ice, which will make the water level even higher and increase the risk.

In addition to the flood gate, the outlet of the hydropower station, and the overflow port are connected to the upstream and downstream of the dam.

However, the overflow had already been blocked, and it would have to be blasted to reduce the pressure on the upstream dam.

Xue Bin also said that new channels could theoretically be dug on both sides of the dam to divert water from the reservoir directly downstream, so that upstream water could flow downstream without having to pass through the dam alone.

It is also to prevent this from happening in the future, causing the water level to be too high and there is a risk of washing away the dam, and at the same time to prevent all the zombies upstream from crowding around the dam.

Of course, this proposal needs to be discussed with the military after returning home, and then they will make a decision to implement it.

The upstream of the dam is a reservoir, and the water surface is very wide, so the main force of opening the river is naturally Taozi, Qin Wen and Fei Yang, the three superpowers, as for Su Ruan Ruan, she can kill zombies, and she is not a fire system, so she can't really help.

Opening a river requires fire, but if the fire isn't strong enough, it's easy to break the ice, and the ice drifting on the river will crash into the dam along the current, causing damage to the dam.

Therefore, it is necessary for these powerful people to exert their maximum power to melt all the ice near the dam, and there is absolutely no way to allow too much ice to break.

They were divided into two groups, Tao Zi and Qin Wen on the left, Fei Yang on the right, and the rest of the people were divided into two sides to provide support, or kill the mutant fish that might run out of the water.

Once they were in groups, they were ready to go.

Xue Bin gave an order, and Tao Zi Qin Wen shot at the same time.

They use both wind and fire.

The wind system supports the fire system, which is used to evenly melt the ice on the water surface.

Because they had explained to each other in advance, both sides used hot air at the beginning to gradually reduce the thickness of the ice.

The temperature of this step is not too high, and it is important to pay attention to a gradual process, the ice near the dam melts faster, and the farther away, the less the effect of the hot air will be.

Until the ice near the dam decreases to a certain thickness, and both sides increase the output at the same time, the temperature of the hot air becomes higher and higher, and all the ice blocks near the dam turn into water, and then begin to spread far away.

The hot air evenly heats the ice cubes, and does not break up a single piece of the ice, so even if the ice in the distance melts, it remains connected, and the ice and water are clearly separated, so it is impossible for all of them to float over and crash into the dam.

However, this requires a very high degree of cooperation to be able to do it, Xue Bin was stunned, he also thought that there would be a steady stream of ice cubes floating over, and it took a long time to keep solving those ice cubes, but now not a single piece of ice is broken, as long as they maintain this momentum, the work of opening the river can be solved soon.
