The cavalry was going north, and the further they went, the colder it became.

It's almost April, but it's still cold, and it's snowing heavily in some areas.

At the moment of approaching Youzhou, the weather is even colder, and there seems to be no taste of spring, it seems that it is still very cold in winter, and it is still extremely cold.

Li Mu estimated that the temperature was below zero.

"It's too cold here!" Li Mu frowned slightly.

"Not only here, in recent times, the climate in the world has generally been declining, in some areas of the south of the Yangtze River, it is still snowing heavily, and the temperature in some counties near the South China Sea is also dropping...... "Hua Wuying was born in the Xuanjing Division, and knows some unknown secrets.

"Last year, in some areas, the north suffered drought, floods, and some areas suffered locust plagues, and grain production decreased one after another...... Fortunately, there is a reserve of grain in the imperial court's grain depot, which can support it, but the situation in the imperial court is also deteriorating!"

Hua Wuying said about the situation in the whole country.

The climate is becoming more and more abnormal.

In the Jiangnan area, the weather used to be hot, and it doesn't freeze in winter, but now it's freezing.

In the summer, there is a severe drought, or a flood.

In the past few years, grain production has been reduced, and the people are living in dire straits, and grain production in many areas has been continuously reduced.

"Could it be that the era of the Xiaoice River has come...... Grain production will cause chaos!" Li Mu said worriedly, and couldn't help but think of the scene at the end of the Ming Dynasty.

Hua Wuying said: "There are thirty celestials in the imperial court, as well as thousands of great masters, a special squad of nearly 10,000 people, an elite army composed of 300,000 innate martial artists, and nearly a million local troops...... Who dares to make trouble. Whoever makes trouble will die!"

Ji Xuewei also said: "The people's lives are a little harder, but they can barely make ends meet...... No one is uncomfortable!"

Li Mu suddenly realized.

This is not the end of the Ming Dynasty, but a high-martial world.

An innate warrior can resist white soldiers with one enemy and hundreds.

Grandmasters, Great Grandmasters, etc., are even more terrifying in combat.

As for the celestials, one person is an enemy country, and one person is against ten thousand armies, which is even more terrifying.

Those high-level martial artists are enough to suppress any turmoil in the world.

As long as those high-level martial artists don't die, the world will still be chaotic.

After walking for a hundred miles, a big river appeared in front of him, but the river surface sounded violently, and suddenly Li Mu was on guard, and everyone else was also on guard.

But soon, Ji Xuewei said with a smile: "The husband is not an enemy in front of him, but the Marquis of the Northern Wilderness who leads the guards, builds a river dam, and builds a river canal......"

Walking off the war horse, Li Mu, Hua Wuying, Ji Xuewei and others went one after another.

Sure enough, by the river, one by one the warriors were digging the river and building ditches, and the number of people was small, only less than a thousand people, but the efficiency of action was indeed very fast.

I saw a thousand catties of stones, carried by a warrior and moving quickly; another warrior, holding a huge shovel, one person high, was digging; and another warrior, resisting a high Luo basket, carrying sand on his back, moving quickly.

All the warriors are holding large tools, carrying out riverbed operations and building water conservancy.

The farm tools here are generally one size larger, but when they are moved, they are all extremely profitable.

Li Mu was slightly stunned.

Miracles are made vigorously.

As long as you have enough strength, there is nothing you can't do.

The construction team is only more than 1,000 people, and the lowest cultivation is also innate, half of them are grandmasters, and there are dozens of great grandmasters, one celestial, they are like migrant workers at the moment, and they are carrying out construction operations.

There are no excavators, rollers, loaders, sewage pumps, jacks, crushers, steel processing machines, sprinkler trucks, etc., all of which are used for primitive manual work, but the work efficiency is much higher than that of later generations of mechanization.

There is no excavator, but the digging speed of an innate martial artist is equivalent to a small excavator, the grandmaster is a large excavator, and the great grandmaster is a super excavator.

There was no road roller, and a grandmaster directly pushed 10,000 catties of stones to the ground.

There is no loader, and the huge basket mine is directly carried manually.

There is also a crusher, when the stone is broken, the true qi is directly urged by the great grandmaster to shatter the stone.

More than a thousand high-level martial artists are doing their work at a speed faster than the speed of the construction team on the earth.

Seeing a group of people coming, many warriors just glanced at it and continued the construction.

Only the celestial figure temporarily stopped the task in hand and said, "Who are you?"

Ji Xuewei stepped forward and said, "Meet uncle, I'm Xuewei...... As for this is my sister and the daughter of the King of Zhenbei, Hua Wuying, this is my husband, Wushuang Marquis Li Mu!"

"It turns out that it's you!"

The Marquis of the Northern Wilderness was covered with mud at the moment, but he just nodded and said, "You have been requisitioned by me, and now we will build a river dam together!"

Ji Xuewei was about to say something.

But as soon as Li Mu pulled her hand, Ji Xuewei was silent.

"Okay!" Li Mu said: "It's just that girls still don't participate, it's enough to have us men!"

The Marquis of the Northern Wilderness said: "Good!"

Li Mu summoned and said the task, and everyone immediately accepted it happily. All kinds of tools were picked up, and under the command of Li Mu, construction began.

Half a day later, Li Mu frowned slightly and said, "Master Hou, tell me about your water conservancy plan!"

"The construction of river dams is mainly for flood control, and at the same time it is conducive to irrigation ......," said Beihuanghou.

Li Mu shook his head and said: "Water conservancy construction is not bad, but it ignores the overall situation!"

As he spoke, Li Mu squatted down and drew sketches on the ground.

The water conservancy plan of the Northern Wilderness cannot be said to be wrong, but can only be said to have the limitations of the times. However, Li Mu had the vision of his previous life, but he proceeded from the overall situation, built reservoirs, built barrage dams, and established macro overall benefits.

After analyzing for a moment, the Marquis of the Northern Wilderness nodded and asked again.

Li Mu also responded.

There were quarrels and disagreements in the middle, but gradually, the plan was constantly revised and finally finalized.

Construction continues, and the plan becomes more and more perfect.

About a month later, a huge reservoir and barrage dam took shape.

Such a huge amount of work was completed in less than two months, with less than 2,000 people.

Li Mu was amazed in his heart, and he made a miracle vigorously.

"Thank you for your help!" thanked the Marquis of the Northern Wilderness.

"Without him, it's just a small thing!" Li Mu said with a smile, "Originally, when I went to Youzhou City, I wanted to meet my seniors, but now I just happened to meet in advance!"

The Marquis of the Northern Wilderness said: "I owe you a favor, if you encounter trouble, report my name, and someone will give you face in Youzhou!"

Li Mu said: "Does Master Hou know how the governor of Youzhou died?"

The Marquis of the Northern Wilderness said: "Youzhou Zhizhou is dead?"

It seems that for the first time I know in general.

A servant stepped forward and said, "Master Hou, just two months ago, he died of poisoning!"

"It turns out that a Zhizhou died!"

The Marquis of the Northern Wilderness said, as if an ant had died, and said, "It's the first time I've known about it. It's too dangerous to be an official these days!"
