However, as the flood in the north hits, it hits the northern wall. After the flood hits the wall, it diverts to both sides and flows into the southern plains.

After the flood entered the gentle area, the water level line also dropped, so although the south side of the northern border is relatively low, the flood level is also low.

And, most importantly,

Because the overall terrain of the north is high in the north and low in the south, the groundwater in the city also flows south.

There is almost no waterlogging in the northern part of the city, and there will be some in the southern part, but not many.

Xiao Jun stood on the wall of the city outside the north, looking at the endless ocean in the south, and felt a little moved in his heart that the team that built this base before was really outstanding.

The Northern Base, which Yuan Zhi spent a lot of money to build before the end of the world, was indeed powerful.

Under the raging flood, the villages and woods are invisible.

There are only some small hills in the distance, which are exposed to the water.

...........

...........

The latitude of the oil city is lower than that of the northern border and the northwest base.

The temperature rebounds faster, so there is more melting snow water.

But the terrain here is high in the southwest and low in the northeast, and floods flow from the southwest to the northeast.

Especially in the southwest, there is a Nanwan Lake, where the flood flowing in the southwest is the most terrifying.

There are mountains in the west, northwest and south of the oil city, and relatively flat in the northeast.

The oil city is built here in the center of this area.

However, because this plain is relatively large, the water has become much smoother after the flood flowing into the mountains has been buffered for ten kilometers.

However, as the temperature rises, the melting rate of snow melting water accelerates.

More than a month ago.

When the temperature was still below zero, they were already increasing the buffer city wall. After more than a month of increasing the buffer city wall, the buffer city wall has reached a height of 24 meters.

This month, a lot of points have been consumed.

For the survivors in the trading market, there are 12 average points in the point number card.

Everyone is rich.

The oil city issued a large amount of points, which resulted in the points in the hands of survivors being able to purchase more than the total amount of food currently owned in the oil city.

Exceeding 40% is huge.

Once a bank run breaks out in the trading market, the oil city will face the dilemma of being unable to exchange food.

The benefits of issuing a large amount of points can allow more than 100,000 residents to participate in the construction are also very objective.

In just over a month, the walls of tens of thousands of acres of buffer city increased from eight meters to 24 meters!

The construction progress of nearly 30,000 mu of greenhouses is 79%.

A 150,000-acre greenhouse and 1,500 greenhouses have been officially put into use and grain has been gradually planted.

Since the grains with higher yields per mu are grown, such as corn, potatoes, and sweet potatoes.

Before the end of the world,

The average domestic corn yield per mu is 1,000 kilograms.

The average yield per mu of sweet potato is 3,000 kilograms.

The average yield per mu of potatoes is 2,500 kilograms.

But this is only the average yield per mu in China. According to different planting methods, as well as soil, fertility and other factors, the yields in each place are huge.

However, the grains grown in the buffer city can be compared with the big camphor tree base, because the planting methods used are greenhouses, and the planting technology is like a lineage.

It is a high-quality planting, and in recent years, the planting level of the camphor tree base has been continuously improved, forming refined and intelligent planting.

Based on the yield per mu of the Dazhangshu Base in the last quarter, the yield per mu can reach 3,500 kilograms.

As for the grain that has been planted so far, the annual yield per mu can reach more than 20,000 tons.

Once all greenhouses in the buffer city are planted with staple food, based on the current population of the oil city, the food self-sufficiency rate of more than 80% of the oil city will be achieved.

...........

The temperature in the oil city rose to above zero and the flood outside suddenly increased.

Originally, they thought that the wall built more than 20 meters can definitely withstand the impact of floods.

Unexpectedly, the water level rose faster than they expected.

Three days ago, the water level line was only 7 meters high.

Today, three days later, the water level line height actually reached 19 meters.

Five o'clock in the morning.

I have been detecting the east wind on the water level outside and contacting Ju Tianrui.

"Director, the water level line is more than 19 meters."

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! Ju Tianrui took a deep breath, and his red eyes showed that he didn't sleep well last night.

He pushed open the door and walked towards the conference room.

There are many people in the conference room.

There are two other water conservancy experts.

As soon as Ju Tianrui came in, he spoke, "The height of the water level has reached 19.1 meters."

He will come to report every 10 cm increase in the water level line.

One of the water conservancy experts turned extremely ugly when they heard this.

He quickly stood up and said, "20 meters, according to my observation, the water level line must not exceed 20 meters!"

Just finished speaking.

Li Zhengping next to him mocked:

"At first you said that the water level line would not exceed 15 meters, but later you patted your chest and said that it would not exceed 18 meters. Now the water level line has reached 19 meters, and you said that it would not exceed 20 meters. Otherwise, you can widen the number a little, saying that it would not exceed 24 meters..."

At present, the height of the buffer city wall is only 24 meters.

If the water level really reaches a height of 24 meters, there will be no chance.

I can only give up the buffer city and retreat to the trading market.

All the hard work in the buffer city these days was wasted.

They, including San Shu, believe in these two water conservancy experts who were excavated from the trading market.

I believe they have real skills and have also undergone some assessments.

The trading market has been able to develop to this day because it is to know people and take good care of them, and to leave professional things to professionals.

Therefore, many experts and talents from all walks of life have emerged in the trading market.

It also promoted the development of trading markets.

Among them, in terms of economic system, there are several economic and monetary experts who created it. They were piloted in the trading market and later found that it was indeed useful and spread to the headquarters of the North and Dazhangshu Base.

etc.

But these two water conservancy experts are too watery.

One of the water conservancy experts looked at Uncle San tightly and said confidently:

"Minister, you believe me, really, this time I dare to use my head to guarantee it! It will definitely not exceed 20 meters."

After he finished speaking, the entire conference room was extremely quiet.

Everyone looked at Uncle San.

Uncle San's index finger gently tapped the table, making a slap sound.

It was like a heavy hammer hitting the hearts of these two water conservancy experts one by one.

After a long time, Uncle San said softly:

"I value talents, but you two have proved with practice that your ability is not good."

"If you are sure to predict the water level height, then don't say it, I won't blame you either..."

"I'd like to make other plans too..."

"But you said so confidently that you can predict it, but the result was slap in the face, which is ugly..."

"The military order you made last time forces everyone to believe in you. You have won our trust and that military order will be implemented."

thump!

A water conservancy expert knelt down and crawled towards Uncle San.
