Follow Chen Lian into the gate, cross the corridor, and walk across the bridge. Finally, he met the Chen family's chief minister, Chen Zheng, in the study.

Chen Zheng was in his early sixties, with white hair and beards and long-lasting age spots on his face. He walked tremblingly, as if he could fall down at any time.

In modern times, this age is in the golden age of life. If you have no illness or disaster, you can at least exert your remaining energy for ten years.

But in the Han Dynasty, it was about to go to the countdown to life.

This is also Cao Ang’s original intention of building a medical school.

During the Han Dynasty, the average life expectancy of a person was pitifully low. If it did not improve, the population would not increase significantly.

If you want to realize your dream of striving for the world, no one can do it.

"Sister Cao Ang, pay homage to Mr. Chen."

In front of this master, Cao Ang did not dare to act like a young master of Sikong Mansion and honestly held the courtesy of his juniors.

Chen Zheng was supported by Chen Lian and sat down, saying, "Did the eldest son come for the land of Quandian Village?"

"Old Chen Mingjian, that's right!"

Cao Ang replied.

"Last year, your Cao Mansion hoarded a lot of land. The eldest son still felt that it was insufficient. He also had to worry about the little land of my Chen family. Don't you feel that you are insatiable?"

This old man is too disrespectful.

Cao Ang was angry, but he smiled and said, "Old Chen is such a bad thing. I want to replace other lands at the same price, not to take advantage of it."

"Equivalent replacement, this word is interesting."

Chen Zheng thought for a moment and said, "That's not impossible. I dare to ask the eldest son why he insisted on the land in Quandian Village?"

"Please forgive me for not telling you this, Wen Hua."

Cao Ang hurried behind Wen Hua.

Wen Hua stepped forward and said, "Reported to Mr. Chen, Quandian Village has a total of more than 3,000 land. The eldest son is willing to replace the top-grade land with 3,000 yuan in the south of the city. Please forgive me."

How could Wen Hua have no choice but to be the chief supervisor of the Sikong Mansion? After receiving Cao Ang's order, he immediately went to Quandian Village and investigated the land, population and scenery there clearly in recent years.

Chen Zheng seemed to have expected this and said calmly: "It's not impossible to replace it, but the land in Quandian Village is a low-level land, and the grain output has never been high. After I replaced it with you, Sikong blamed it?"

This old man was afraid of Cao Cao's tyranny.

Cao Ang patted his chest and promised: "Don't worry, Mr. Chen, I am willing to make a document. The replacement is done by the younger generation personally. The consequences caused by the younger generation are borne by the younger generation alone and have nothing to do with the Chen family."

"Okay, the eldest son is happy, then this matter will be settled."

No one will refuse such a good thing as a sub-field to replace the same superior field. Chen Zheng was only concerned about the consequences afterwards.

The head of the Cao family is not Cao Ang. Cao Cao was fighting abroad and replaced the superior fertile land from Cao Ang with inferior fields. No matter how you look at it, there is a suspicion of bullying the stupid son while the parents are away.

The Chen family cannot bear the reputation of taking advantage of the situation and robbing the Cao family! Besides, if you rob the Cao family, look at the great man, you will definitely not have more than one hand to have the courage.

But now it’s different. Cao Ang came in person and established another statute. Cao Cao wanted to pursue it again later. He could say that your son insisted on doing this, and he came to my mansion twice for this. I can’t stop him and can only satisfy him. If you don’t believe me, look, the statute is here, and the words are black and white, and I can’t deceive people.

In this way, Cao Cao had nothing to say.

After establishing a document and changing the land deed, Cao Ang didn't stay for a long time and left after chatting for a while.

After he left, Chen Lian asked Chen Zheng, "Father, why did the eldest son insist on asking Quandian Village? Is it what he wants to do, or what is in Quandian Village?"

Chen Zheng shook his head and said, "I don't know whether to be a father. Now Cao Cao is in great power. Cao Ang is the eldest son of the Cao family. It's better not to offend him."

"But my father is also very curious about why he has to pay such a big price to Quandian Village. There is nothing wrong recently. You can walk with him more and see if he has other purposes or is really a bad brain."

"yes!"

Chen Lian bowed to accept the order.

After leaving Chen's mansion, Wen Hua couldn't help but ask: "Now Quandian Village has been obtained. Can the eldest son tell the old slave the purpose of replacing this land?"

Cao Ang flipped the deed several times and handed it to Wen Hua and said, "Nothing else, I heard that there is Nirvana stone there."

He remembered that the word "coal" is not called this name when he reached his mouth, so he quickly changed his words.

Wen Hua said with a tragic howl, "My eldest son, what's the use of this thing? Although it can be burned, it's toxic and it's not worth anything at all."

"You know what a fuck."

Cao Ang said, "I tell you that it won't take long to replace charcoal and become a magic weapon for heating. So now, immediately, you will immediately grab Quandian Village firmly in your hand. Our Nirvana Stone, a piece of scum, cannot be stolen by others."

Wen Hua naturally didn't believe this kind of nonsense, but the situation was stronger than that of a human. After all, his little arm could not resist his thighs, so he had to act on order.

...Time flies, and ten days are in a flash.

In the past ten days, Cao Ang has been devoted to the decoration of the restaurant, and he rarely even returns home.

This move made Mrs. Ding dissatisfied and sent someone to urge her many times.

After ten days, the restaurant completely changed its appearance. The low coffee table disappeared and was replaced by high-legged tables and chairs. Four people had a long table against the wall and the Eight Immortals table was in the center.

In addition, there is a large stove between each three tables, with the chimney facing vertically, turning a corner at the roof and extending to the window.

The Nirvana stone in the furnace burned red. Not only did he not feel the cold, but he was a little hot.

Ten days ago, he drew the drawings and ordered Zhoushan to create a batch of stoves that were common in rural northern when he was a child. He put them into the restaurant lobby, and the restaurant instantly became much warmer.

Originally, he wanted to build a boiler directly, but the facilities were too cumbersome and the current conditions did not allow it at all, so he could only settle for the second best.

Wen Hua looked at the burning iron chimney and said, "Young master, great talent, in this way, the poison of Nirvana stone will be discharged outside the house, and the people in the house will no longer be afraid of being poisoned."

"That's because you are too stupid. You can't even think of such a simple way. Put something as good as Nirvana in the ground to grow hair. Now you know the value of Nirvana!"

Cao Ang cursed with a smile.

When talking about the heating of the man, Cao Ang was full of resentment.

The heating of Dahan relies entirely on charcoal, but charcoal is difficult to burn and the price is high, so ordinary people cannot afford it.

There is no earthen kang or quilt (the cotton has not been spread to China yet), and wealthy and gentry can still get some animal skins to keep warm, so ordinary people can only rely on resisting.

The winter of this era is very cold. Every winter, many adults freeze to death, let alone children in cradles.

"I know, I know, the young master is very talented, and it is hard to reach a villain."

Wen Hua said.

"By the way, have the stoves in the house been installed?"

Cao Ang asked.

Wen Hua hurriedly said, "Well, all the rooms of the wife and the young master have been installed, and the wife also praises the young master for being filial!"
