The night of February 18th.

The night was dark and starless, and the moon was covered by dark clouds.

The street lights at the base of Da Zhangshu illuminated the aisle.

Standing on the wall, Li Yu looked at the entire base.

The wind picked up and made the clothes rustle.

"The wind is blowing." The second uncle looked at the mountains and forests in the distance. In the darkness, he could especially see the shapes of the mountains and forests.

"Yes, the wind has picked up." Li Yu murmured.

It seemed to be answering the second uncle's words, but also seemed to be speaking to himself.

The rice and other grains on the waterway are collected as early as the afternoon, transported to the food processing plant for air-drying, and then the dried rice is sealed in a sealed underground warehouse.

The underground warehouse is extremely sealed, and even if it is completely flooded, water cannot penetrate inside.

Over in the greenhouse, Anya processed the human feces in the septic tank and made it into earth-moving compound fertilizer.

In recent days, Li Yu has given their collaborators and non-staff some tasks to help repair the base and make some things.

They helped with some things in the base and received a very small amount of food, so they were not in a hurry to go out yet.

However, some people see that the weather is getting warmer and are planning to go out early to perform tasks and redeem their contribution points in two days.

Li Yu considered that the upcoming heavy rains and floods would be very dangerous, but he couldn't tell them. He could only give them some things they could do in the outer city.

If we want to develop in the future, we will definitely need people, people who can be trusted. At least compared to other outside people, these non-staff and collaborators are much more reliable.

The wind at night is getting stronger and stronger, and there is a faint dampness in the wind.

Tonight, Li Yu was not on duty, but he still stayed on the wall.

This evening, he went out from the city and walked around the wall to check the situation outside the wall.

After checking out the drainage problem a few days ago, Xu Zhen has been repairing some places in the base these days.

He deliberately dug some areas at the water inlets, drainage outlets, and low areas of the garden to connect them to sewers, so that nearby accumulated water and rainwater could flow here, minimizing the risk of waterlogging.

At ten o'clock at night, in the duty room at the main entrance.

Yutong, Li Haoran, Zhou Zhiwei, Li Zhengping, and Li Yu were all indoors, while Li Gang was patrolling outside.

The personnel who were originally on duty were arranged to have two groups at the same time.

One group is fixed around the duty room, and the other group patrols up and down the fence.

Except for the five people at the gate, there are only three people in the other four duty rooms, totaling 17 people.

There are also 6 mobile patrol officers.

In total, there are about 23 people on duty in one shift.

This is minimum alert staffing.

There are a total of four levels of protection for the base walls.

The fourth level of alert state, as it is now, is a fixed alert state.

The third level of alert state is usually when a heavy rain comes and a zombie wave breaks out. The combat readiness personnel is doubled to about fifty people, and heavy weapons such as mortars are pulled out from the duty room.

In the second level of alert state, when the zombie wave breaks out at its most ferocious, or a powerful foreign enemy appears, the number of combatants increases to one hundred to two hundred.

The first-level alert state has not been activated so far. As long as the first-level alert is activated, it is a matter of life and death in the base. All adults in the base must come up to resist the enemy.

Looking at the surveillance screen, the wind was blowing the tree branches swaying, and under the weak light, the outside looked a bit intrusive.

"The temperature has dropped a bit too quickly tonight." Li Haoran looked at the screen and said.

Zhou Zhiwei tightened his clothes and said, "Who says it's not the case? When I came here tonight, I even put on a coat. But the weather has changed so much. Who would have thought that not long ago it was still dozens of degrees below zero."

Li Haoran nodded and said: "It was more than 20 degrees during the day, how many degrees is it now?"

Zhou Zhiwei pursed his lips, shook his head and said: "I just took a look and the outdoor temperature was less than five degrees. It's colder tonight than yesterday, but the temperature of five degrees is suitable for the current month. It's still spring.

Not yet."

Li Haoran complained: "Don't talk about the month. Look, has the weather been normal in the past two years? It's too abnormal."

Zhou Zhiwei also chimed in and chatted a few words, while Li Zhengping raised his head and listened to them.

Li Yu on the side was trimming his nails with a nail clipper and did not participate in their conversation.

Yutong, who was next to Li Yu, was keenly aware that Li Yu was a little different from usual.

He lowered his head and said softly: "Brother Yu, are you worried about something?"

There was a hint of worry in her eyes. She knew that Li Yu had a heavy burden on him. As the person in charge of the Da Zhangshu Base, he had too many things to consider.

The future and life safety of the entire base depended on him.

But Li Yu rarely shows it, and he appears to be tough and strong, as if he will never be defeated.

Hearing this, Li Yu raised his head and said with a smile: "It's okay, it's okay. How about I help you on duty? You go back to sleep first."

Yutong shook his head and said, "No, it's my turn to be on duty. You'd better go back and rest early. You don't have to stay with me here."

In her opinion, Li Yu stayed here so late just to accompany her.

When Li Yu heard what Yutong said, he couldn't directly say that it was not because he wanted to accompany her that he stayed on the wall so late.

He wanted to wait here and see if it would start raining heavily on the 19th as he remembered.

He remembered clearly that in his last life, it started to rain heavily at around three o'clock in the morning on the 19th, but he was in a city in the north at that time.

I don’t know when it will start raining heavily in Xincheng in this life.

After all, the place is different.

Heavy rains and floods did not occur at the same time. Instead, there were heavy rains for several days, and then suddenly one day, floods tens of meters high came.

This chapter is not over yet, please click on the next page to continue reading! Whenever something is about to happen, Li Yu's behavior is not much different from usual, but he is extremely nervous inside.

Afraid of being different from the previous life, and afraid of being the same as the previous life.

When the flood came in the previous life, he happened to be in that tall building, but he was not on the top floor, but on the ninth floor.

After all, in the apocalypse, without electricity, it would be very troublesome to climb up and down.

The location on the eighth and ninth floors is not only a little distance from the ground, making it less likely to be discovered by zombies, but also makes it easier to search for supplies during the day the next day.

When heavy rains hit, the water level rose very slowly.

It was 3:30 in the afternoon when the flood broke out.

He felt the building shake slightly, and when he realized the flood was coming, it was already too late.

As if desperate, he packed up his bed and ran upstairs.

In 30 seconds, he climbed six floors to the fifteenth floor. About 40 meters away, the flood rushed directly towards him.

There were also zombies in the flood, and some zombies were directly carried by the flood and rushed into the building.

Holding his breath, he swam up another five floors in the water. On the way, he encountered a zombie in the water and was almost bitten by it. If he hadn't blocked it with his backpack, he would have died.

Infected by zombies.

He didn't know how high the flood was at the time, but at that moment, he knew that he had to keep running up to have a chance of surviving.

He survived!

When I swam from the water to the 20th floor, I was breathing heavily and looking at the water, I felt like I was almost suffocating, and I felt lucky to survive the disaster.

As he watched, he smiled. After laughing, his face showed no expression for a few seconds.

He climbed up again. He didn't know if this flood would come again later, and zombies could survive in water, so he could only keep going up.

He walked all the way to the top floor, then set up various obstacles in the middle aisle and closed the hydraulic door on the top floor. It was not until that moment that he relaxed.

However, when he reached the top floor, what he saw was the entire submerged city.

The zombies in the water that make people feel numb, with their heads sticking out, appear like ants on the surface of the water.

This scene in my mind will always come back to me these days.

This scene can be ranked among the most terrifying scenes he has ever seen.

In the duty room, there are also two simple bunk beds.

When on duty, with so many people on duty at the same time, it will inevitably be a bit difficult. Instead of forcing them to take a break, it is better to take a small shift each.

Everyone takes turns to rest for ten minutes, half an hour and so on.

Li Yu was not sleepy, but his mood could not calm down.

He is very worried that this flood will have a devastating impact on the Da Zhangshu base.

If calculated solely from the perspective of altitude, the average altitude of Xincheng is more than 100 meters higher than that of the city he was in in his previous life.

Moreover, the Da Zhangshu Base itself is in a relatively high place, so if measured by altitude, there should be no problem.

But the key point is that because Xincheng is a mountainous landform and does not flow through a plain, the natural water level will be much higher.
