The old man has been farming all his life, and he has a lot of experience in how to grow crops, which can be seen from the autumn plough ploughing the ground.

As soon as the boundary of Guannai enters winter, the snow is covered, and the land is naturally frozen hard, and it is impossible to plow the ground in winter.

Autumn ploughing has many benefits, not only can the pests and diseases hiding in the soil be turned out of the ground, frozen to death in winter, in the era of no pesticides to lay the foundation for the next year to reduce pests and diseases, but also can relax the soil for the next spring planting.

If it weren't for the fact that before Gao Sheng's crossing, the business scope involved was agriculture, and I am afraid that he would not know the benefits of plowing the land in autumn before he had never planted the land.

Gao Sheng knew that in order to convince the old man and the old lady, he could not directly say the benefits of adding slaves and maids to the family, and he must seize the second elder to choose to compromise for his sake.

"Aye, A-Niang, Sheng'er is thriving now, and the friends she has made are either the king's daughters or the sons of the nobles, if the master's family personally serves them, it will be too embarrassing, and our family will inevitably be looked down upon."

After he finished speaking, he secretly glanced at the faces of the old man and the old lady.

The old man was obviously stunned, and the old lady looked at the old man with blank eyes, in this era when women marry chickens and dogs, the old lady herself has no idea, and the old man has the idea.

The old man was silent for a while, then he glared at him and said, "You coward, pouting my ass, I know what kind of fart you are putting." ”

Gao Sheng smiled embarrassedly, the old man was still Jiang Lao's spicy, and he could see at a glance what he had in mind.

But seeing the old man's expression, he also knew that the old man was moved, knowing the son Mo Ruo's father, in the same way, knowing the father Mo Ruozi.

Sure enough, I only heard the old man say again: "Aunt Zhuzi has found a dozen slaves and maids for you, you can do it yourself." ”

The old man's meaning couldn't be clearer, and Gao Shengxi said: "Thank you Aya for your success." ”

The old man said again: "Don't recruit these slaves and maids into the door, it will harm others." ”

He nodded hurriedly and replied: "Sheng'er should work hard, and in the future, there will be not only slaves and maids, but also ministry, so that Aya and A-Niang will have slaves and maids and trilogy to accompany them when they go in and out." ”

A hint of joy flashed in the old man's eyes, but he still kept a straight face and said: "I believe in your coward's words to call it hell, and if you beat your coward, you will fool people." ”

Gao Sheng smiled awkwardly, smiling at the uncompetitive goods of his predecessor.

At sunset, when I finished work and went home, I entered the courtyard and saw Cheng Chubi and Li Jingye around the table in the courtyard, and Gao Yue was standing in front of them, telling the story of the Monkey King to the two.

The story of the Monkey King, the two of them didn't listen to the end, and after visiting the villa, they begged Gao Yue to tell them the story of the Monkey King from the beginning.

Gao Sheng went directly into the kitchen and taught the cook how to stir-fry and cook food.

The food production process in the Tang Dynasty was steamed, boiled, stewed, and roasted, and stir-fried was rarely used.

The cook was going to cook, but she was stunned when she looked at the pots and pans in the kitchen and the spatula used for stir-frying.

After all the slaves and maids were there, he had to cook the first few meals himself, and the cook was studying beside him.

When the dishes and meals were ready, he beckoned Cheng Chubi and Li Jingye to eat, and they were still dissatisfied, and they wanted to continue to listen to the story of the Monkey King.

When it was time to eat, Cheng Chubi and Li Jingye were directly captured by the table full of delicacies, and they devoured them so much that they couldn't wait to swallow their tongues too.

The next day, Gao rose early in the morning.

After breakfast, he hid in his studio alone and began another of his studies.

Gao Sheng lay on the long case, staring at the long steel ingot he had bought in the village blacksmith shop before, and he was out of the way.

In this era, there are no electronic furnaces to control the temperature, and it is difficult to make a knife with both hardness and toughness.

He is now thinking about using the knowledge he knew when he was playing outdoors and researching outdoor knives to make a knife with both hardness and toughness.

There was a simple furnace and tools for blacksmithing.

Originally, he wanted to ask the blacksmith from Shanghe Village to come and help, but when he thought about it, if he really made a high-hardness and high-toughness carbon steel like Uzi steel, if the method of making it leaked out, he could imagine his fate.

Just imagine, if everyone had a sharp weapon in their hands to cut off the opponent's blade, this kind of thing that could almost affect the times, how much trouble it would bring him, he couldn't estimate at all, so he could only go on his own.

There is no electronic furnace, you can only estimate the time by yourself, repeatedly test the time of each quenching and tempering, and compare it with the tools of this era to test the hardness of carbon steel, as long as you test the correct charcoal and quenching time, that is the most ideal hardness and toughness of carbon steel tools.

Failure is the mother of success, and he doesn't believe that he can't make a good hunting knife alone, which is an obsession as an outdoor enthusiast.

Light incense to estimate the time, and then burn the charcoal vigorously, throw the steel ingot into it, quench and smelt it many times, and temper it many times.

In this way, he has been experimenting, quenching and tempering time matching, but he has never found a correct way, and the smelted carbon steel cannot reach the hardness and toughness he wants, either too hard, no toughness, or too soft, even the knives of this era are not as good.

Tossed for most of the day, but returned in vain, he was already tired and unhuman.

Out of the studio, came to the courtyard, he lay on the recliner, thinking about the current tool heat treatment knowledge in his mind, but it is all data, such as how much temperature is required for quenching, and how much temperature is required for tempering, which are the quantitative standards of modern electronic furnaces, but this is the Tang Dynasty, how to accurately test the temperature?

Temperature, temperature ...... Mercury.

Gao Sheng thought of the mercury thermometer, and the whole person ejected from the recliner, startling Cheng Chubi and Li Jingye, who were resting in the sun, in the courtyard, and the story was interrupted.

Cheng Chubi asked with a look of resentment: "Third brother, you are a corpse!" ”

Gao Sheng rolled his eyes and didn't bother to pay attention to him, then lay down on the chaise longue and continued to think.

Cheng Chubi and Li Jingye looked at him as if they were fascinated, glanced at each other, and continued to lie on the recliner to be lazy.

Gao Sheng sighed slightly, obviously mercury to test the temperature of quenching and tempering, because the temperature of quenching and tempering is much higher than the temperature that mercury can measure.

In fact, he wanted to use mercury to repeatedly test the temperature of his armpits, and note the height of the mercury rise, that is, about 36 degrees, so that the temperature of quenching and tempering can be measured through mercury.

Later, I thought that mercury could not measure the temperature of quenching and tempering at all, so I had to give up.

Gao Sheng's face was lost, and he sighed in his heart, it seems that he can only use incense to record time, repeatedly test under the burning of coal to think through, and find out the correct quenching and tempering time through the length of time, there is a long way to go......
