At the beginning of the mass grave, I took the villain to open up wasteland and farm

Chang Ning calmly said "Oh", as if not surprised.

Han Mingyuan also looked indifferent, the reaction of the two made Gou Fugui feel a little disappointed.

"Don't you care why you suddenly sacrificed to the mountain god?"

Chang Ning: "I don't care."

Han Mingyuan: "It doesn't matter."

"Tsk!" Gou Fugui knocked on the edge of the bowl with his chopsticks, "Why don't you have any curiosity at all, I heard that hundreds of corpses disappeared from the mass grave on the mountain to the north, leaving a huge hole , and someone saw fire erupting from the mountain this afternoon, those corpses must have been eaten by the mountain god!"

Chang Ning said perfunctorily: "It's okay to read more, and less gossip."

Han Mingyuan added: "Or work more and eat less."

Gou Fugui was indignant, and felt that the two of them were really boring. Just as he was preparing to eat, there was only soup and oil left in the three vegetable bowls in front of him.

"Your uncle, you two are too cruel!"

Chang Ning smiled sullenly, silently pawing the food in the bowl.

Gou Fugui had no choice but to pour the rice in the bowl into the dish, "Everyone is like a reincarnation of a starving ghost. You don't understand the deliciousness of fried rice."

Han Mingyuan put down the bowl, and reminded: "Remember to clean the bowl after eating."

Gou Fugui was furious immediately: "I didn't eat a single bite of the food, and I need to wash the dishes? Are you devils?"

Chang Ning also took the opportunity to put down the bowls and chopsticks, "Leave it alone after eating, and wash the dishes after eating. This is our family's rule."

Gou Fugui gritted his teeth in anger, but could only bear it silently.

If I had known that watching gossip would make me unable to even eat food, I would not have bothered to inquire about offering mountain gods, sorry~~~
It was still early after dinner, so Chang Ning dragged Han Mingyuan to the open space where bricks were piled up beside the yard.

The reserved area of ​​the open space was about 130 square meters, which could not meet Chang Ning's needs, so Han Mingyuan asked Han Mingyuan to cut down a few trees around him, and leveled a few uneven hills to plan a [-] square meter foundation.

Chang Ning has inspected the soil quality, which belongs to cohesive soil, which can meet all the load requirements of the bearing foundation in the natural state, and is a natural foundation that does not require manual treatment.

Chang Ning sketched out the structure of the house with sand and soil according to the idea in his heart, ready to do the preparatory work, and then officially started the construction.

The next day, she brought a bucket of cement and a few blue bricks to find Cheng Erqing's family and Daniu. The four of them sat around in the yard of Cheng Erqing's house, and Chang Ning outlined his house building plan.

Father Erqing has built a house for more than [-] years, but he has never built such a strange house as Chang Ning said.

You must know that most of the houses they build are one-story wooden houses or brick houses. If they build a two-story small building, the second floor must be laid with wooden planks. The cost is low and the cost is low. I have never heard of using concrete. .

After all, the house is for people to live in. If it collapses, it will not only damage the reputation he has built for decades, but also risk life. Father Er Qing hesitated.

Seeing this, Chang Ning took out cement and poured it in the yard, mixed sand and water in front of the three of them, and built a low wall half a person's height with green bricks.

At noon in mid-April, the temperature was no lower than [-] degrees, and the cement was already showing signs of drying when Chang Ning came to the door the next day.

It would take at least ten days and half a month for the cement wall to dry completely. Chang Ning couldn't wait that long, and the current appearance was enough for her to experiment.

Chang Ning handed Er Qing's father the hammer to hit the wall.

Er Qing's father was a little hesitant at first, but seeing Chang Ning's swearing, he also had the courage to smash it.

He had built a brick house with lime as the binder before, and he knew better than anyone how hard a wall like this could be smashed down on the first day.

Unexpectedly, when the hammer was swung down, there was a crisp sound on the wall, but the wall did not move at all.

Erqing's father was so shocked that he couldn't be more shocked, and he intensified a little more with surprise.

This time the wall swayed twice, but it still didn't fall.

It wasn't until the third time that Er Qing's father put away his thoughts of probing and swung the hammer vigorously, only then did he smash a hole in the low wall.

"Chang girl, what is your cement?"

Chang Ning said with a smile: "This is a new type of building material that can harden in air and water. It has high strength and strong adhesion. If steel bars and fibers are added to it, the resulting reinforced concrete can make a wall You spend a few days."

Erqing's father couldn't hide his joy, "If you use such materials to build the city wall, wouldn't it be impossible for Yu's army to break through?"

"The strength of the city wall can indeed play a certain defensive role, but the most important thing in defending the city is the defenders. If you blindly pray for the function of the city wall, you will lose sooner or later if you are lucky."

"What's more, the material is not enough to build a city now. When the technology develops in the future and the possibility of mass production becomes available, cement will definitely become popular all over the world."

Er Qing's father agreed: "What Chang girl said is very true, uncle thinks so simply."

Er Qing couldn't bear it any longer, and happily asked, "Sister, when do you plan to start building this house?"

Chang Ning said: "Wait for me to prepare other materials in two days, and start construction in two or three days at the latest."

The three of them rubbed their hands together: "Okay, just wait for the girl to say hello."

Chang Ning taught the three of them the principles of building a house, and then it took two days to prepare building materials such as cobblestones and sand.

Early in the morning of the third day, Er Qing's father beat gongs and drums to pay homage to the Land Lord, and then started construction under Chang Ning's command.

The first step is to lay the foundation, the foundation should not be lower than 20cm deep into the soil layer, and in order to avoid being soaked by rain, it is necessary to hurry up the construction in the weather without rain.

After the foundation is laid, it is time to start the steps of masonry.

Chang Ning took advantage of the night to take out all the cement in his space chip, and then taught Father Erqing and Cheng Erqing how to use it and the proportion of sand and water during the day.

For a new thing like cement, it is as attractive as a beauty in front of a construction worker.

Er Qing's father and the others worked tirelessly. If Chang Ning hadn't counted the time to let them call it a day, they would have had to light the lamp and lay bricks overnight.

In the past few days, Han Mingyuan and Chang Ning were in charge of planting the fields. As for Gou Fugui, Chang Ning asked him to bring a few catties of cucumbers, cowpeas and tomatoes, and then went to Liangcheng to discuss business.

For Chang Ning's trust, Gou Fugui is very grateful. When he left home, he swore an oath in front of Chang Ning and promised to complete the task.

But when he actually arrived in Liangcheng, he ran into obstacles everywhere, and even entered several restaurants, but before they took out the vegetables, the store immediately coaxed him out when they saw that he was not here for consumption.

Gou Fugui had never been so angry in his life, he went back to the herbal tea shed where he and Chang Ning stayed last time, borrowed tea to relieve his worries and drank herbal tea until the pot of tea lost its taste.
