One hour later, Beishan.

As the carriage stopped and the door opened, Zhou Heng jumped down first and stretched his arms and legs.

Although this carriage is warm and comfortable, it is still curled up uncomfortable. It seems that several comfortable sofas will be designed on the carriage in the future, otherwise it will be too uncomfortable.

When Liu Xiuer and Su Xiaoxiao saw that the car stopped, they just lifted the curtains of the car window.

"Second brother, why don't I take Miss Su to find Qingyun. We will go to the kitchen to prepare spicy fish pots for you later."

Zhou Heng nodded, pointed to the village and said:

"Go, Qingyun is in the village. When you ask Miss Bai where they live, they will know."

Liu Xiu'er and his team turned around and drove towards the village at the foot of the mountain.

At this time, Liu Renli jumped down. When he met, Zhou Heng found that Liu Renli had changed a lot.

Although he was still persistent, he became much more calm, which was quite relieved by Zhou Heng. Being able to hide things in his heart is the basic skill of being an official.

Along the way, Zhou Heng had already told Liu Renli what he had done in Beishan these days, what he had planned to do later, including how to use everything on this barren mountain, and it is reported that it was told that all the things and of course the two new crops.

At this moment, standing on the hillside of Beishan and looking carefully, the workshops in this area were arranged in an orderly manner, very spacious and tall, which made him believe that it was built in two months, which was simply incredible.

Thinking of Zhou Heng's method of repairing the ditches, Liu Renli widened his eyes. He believed that Zhou Heng must have a method to dig on the frozen soil. The wide road and workshops in front of him were no longer much more difficult than digging the ditches.

He turned to look at Zhou Heng, "Second brother, tell me, what method can be used to excavate on the frozen soil?"

Zhou Heng smiled and pointed to a place where there were personnel to build the construction site:

"Everything is true, let's go and see it."

Although Liu Renli was anxious, he knew that he would see the most effective. He quickly accelerated his pace and Zhang Huaiyuan supported him and followed Zhou Heng.

The few people moved quickly and came to a construction site that was being built. One by one, the construction workers were wearing rattan hats like melon skins on their heads. The hats were wrapped in thick headscarves and were wearing very thick clothes.

The gloves on your hands are exposed, aren’t they cold?

But in an instant, Liu Renli felt that the construction site was a little higher than the place where they had just stood, and he didn't feel that it was too cold when he took out his hands.

Liu Renli looked closely and found the problem. It turned out that the surrounding area was covered with thick cloth, with several large iron buckets in the middle, and coal burning inside seemed to be burning. You could feel the temperature from a distance.

"Is it because of these fences and iron barrels that heat up?"

Zhou Heng shook his head, "They invented these things so they didn't feel too cold during construction, so they found that there were handles on the edge of the iron barrel, and they could carry them wherever they went, even if they burned, they wouldn't be too hot.

As for the frozen soil on the surface, the people in the village have thought of a good idea. Brother, look here."

As he said that, Zhou Heng walked to a corner of the fence, where there were thick grass on the ground, and some dead branches were thrown in four circles. Zhou Heng pointed to the pile and said.

"The days when road construction was built were much colder than the current weather. They were going to build the road, lay a layer of dead grass and branches, and then ignite it. After half an hour, the frozen soil can be dug half a person high. I think most of the ditches that my elder brother needs should be at this depth."

Liu Renli nodded and gestured to his waist.

"In the county on the west side, the deepest one is waist-deep, and the two counties on the east side are located at the chest. Even if the location connecting the river is only about one person deep, it will be burned twice, right?"

Zhou Heng laughed and kicked the dead branch.

"These things are just available for local materials, but the locations that need to be excavated need to be cleaned up, otherwise they will be wiped out before they burn."

Zhou Heng remembers that the permafrost layer around Beijing, Hebei seems to be about 85 centimeters. In fact, as long as it is burned thoroughly, the permafrost can be melted in one go without delaying construction.

The more Liu Renli thought about it, the more he felt that this method was cost-effective and easy to implement. He just needed to dig to the right depth according to the terrain of each county, and he would not be afraid of waterlogging in spring next year.

"Don't say, your method is really good. We will start implementing it when we go back to various counties."

Seeing that Liu Renli finally breathed a sigh of relief, Zhou Heng smiled and said:

"Brother, don't worry. Since the things you are worried about have been solved halfway, then go and see how the two newly planted crops I have?"

Liu Renli smiled and patted Zhou Heng on the shoulder.

"Let's go and see what baby you have."

Zhou Heng looked mysterious and said with a glimmer of light in his eyes:

"Let me say that, I've been growing in a greenhouse here. As long as the outdoor temperature is suitable for planting, I can go outdoors. Both crops are growing wildly, and the harvest is enough to scare you."

Liu Renli felt that Zhou Heng was a little exaggerated, but she didn't want to hit Zhou Heng and followed him towards a smooth house.

Just as he was about to enter, Liu Renli discovered the difference. This place is not a house for ordinary people. There are high walls on the north and half shorter on the south. The roof is paved with a whole sheet of glazed plates.

From the outside, you can see that there are ridges of land inside, and there seem to be green leaves in the middle.

This time, without Zhou Heng urging, Liu Renli took a step in an instant, saw the door on the side, and opened the door and walked in.

The temperature in the warm room instantly made Liu Renli stunned. Not to mention spring, it felt like early summer. It was so hot that it was sweating instantly.

Looking at the few people in the greenhouse, some of them were wearing sleeveless vests, rolled up their trousers barefoots, standing in the ditch, holding earthworms in their hands.

Seeing Liu Renli and Zhou Heng coming, they quickly threw away the earthworms in their hands and wiped their hands clean on both sides of their pants. Then they started shouting with a smile.

"Stop doing it, look at the young master."

With a shout, everyone stood up and looked at this side, regardless of whether they were not dressed or not, and ran over barefoot quickly.

Even at such a joyful moment, I didn’t forget to look at the ditch and carefully bypass the green seedlings on the ground.

Zhou Heng looked at them and smiled, "I saw the greenhouse from afar. I didn't expect you to plant these two things."

After searching the crowd, Zhou Heng saw Lai Fu coming from behind.

Lai Fu waved to the crowd, "Okay, the young master is here, just do it well. Cultivate these two things. You will definitely benefit from it. Have you forgotten the red envelopes for the New Year?"

As soon as these people were even more grateful, some immediately wanted to kneel down and kowtow. Lai Fu was annoyed and shouted immediately:

"Stop me and I'll kneel out and kneel down. Whoever stepped on the seedlings should be careful of the dog's head."

Such a shout was really effective. These people bowed to Zhou Heng and then went to work.

However, Zhou Heng was very satisfied with Lai Fu's unique appearance. He didn't need to be smart at the manager. As long as he had first-class execution, he could still lead a good team.

Looking at the green seedlings on the ground, Zhou Hengneng now concluded that the greenhouse was planted with potatoes.

"The golden potatoes grow well, but I didn't expect them to sprout so quickly."

Lai Fu squatted down and said carefully:

"This place was not planted on the same day. You see, there are brands on it. Some were selected for germination, some did not have buds, and some were planted after cutting and drying for a day before planting. Although those planted after cutting and drying for a day, they grew faster than those planted before."

Zhou Heng suddenly realized and looked at Lai Fu seriously. He just knew where this thing was a seed and how to plant it, but the detailed process was really unclear.

I really need such a down-to-earth person to be able to experiment in detail to get first-hand information.

Zhou Heng looked down at the seedlings two inches tall above the ridge ditch. Not to mention a few days, this thing grew so fast, but it was obvious that the traces of the small pit at the root were watered here, but he was not good at this.

"Is this watering?"

Lai Fu smiled, "I thought that this thing is so expensive and needs to be cultivated well, so I found bran soaked in water and then watered it. I didn't expect that the germination rate could reach 100%, and the seedlings grew very fast. I just don't know when the golden potatoes will be harvested."

Zhou Heng thought about it and remembered that it seemed that it would take three months to grow potatoes in later generations. Some precocious varieties were used less than three months. The temperature of this greenhouse was constant, and the growth of potatoes was definitely much faster.

"I think three months are fine."

Liu Renli looked around and then approached and asked:
Chapter completed!
