"Hum..."

As Cao Cao clicked on the [Childe] option after Cao Bin's name, the virtual panel slowly changed.

A golden light bloomed, rippling like water waves, and the halo gradually spread.

When the halo spreads, it becomes a 3D screen that displays a high-definition picture.

[In the middle of December of the thirteenth year of Jian'an, you came to Xudu from Qian County, and recognized your father, confirmed your identity, and became the eldest grandson of Cao Cao, the prime minister of the Han Dynasty. 】

As the picture unfolded, lines of cold text appeared at the bottom of the screen, explaining to Cao Cao.

In the picture, Cao Bin took Grandma Ding and the four guards, as well as the workers in the workshop, the bookstore shopkeeper and all the utensils of the entire workshop, and embarked on the road to Xudu.

Along the way, from time to time, there were fierce beast attacks, as well as robbers and thieves, which can be said to have not stopped for a day.

But they were all easily resolved by Cao Bin and the four guards, the beasts became the meat dishes on the table of the group, and the robbers and thieves also lost Qingqing's life.

In the picture, ordinary robbers and thieves were all sent away by Zhang Long and Zhao Hu, and Cao Bin didn't bother to shoot at all.

I saw that they divided five by two, and beat the robbers to the point of crying dad and mother, and fart and urine.

"The skills of these four guards are not weak, Bin'er is well trained!"

Cao Cao's eyes lit up, and he greatly appreciated the four of them.

He learned from Cao Bin's investigation report that Zhang Long and the four were just ordinary civilians.

Three years ago, they wandered to Qian County, and Cao Bin took a fancy to them and left them behind.

Then, he taught them by word and deed, and taught them martial arts and literature until now.

As for the Deng Gouwa who was accepted by Cao Bin halfway, Cao Cao didn't take it to heart.

[Seven days later, the curved plough you developed was confirmed, and it was indeed several times more efficient than the current coupling plow, and your father was very happy. 】

[With the momentum of Qu Yuan's divine plough, your eldest father set the name of your eldest grandson to the ministers, and privately told the ministers that after a hundred years, you will inherit the heir. 】

In the picture, Cao Bin is training a thousand guards given by Cao Cao, and at the same time strictly ordering the workshop to carefully build the world's first curved plow.

After Cao Cao learned the news of the birth of Quyuan Shenli, he immediately picked an auspicious day of the zodiac and took his ministers to the farmland outside the city.

In front of the ministers, Cao Bin set up a curved plow and drove an old ox, and it took less than two hours to plough an acre of land evenly.

So, taking this opportunity, Cao Cao announced Cao Bin's identity to everyone in public.

And said casually: "After a hundred years, I will be succeeded by my eldest grandson Bin'er." ”

As soon as these words came out, everyone's expressions changed slightly, and there were those who were confused, those who were resentful, and those who were happy.

"Huh?"

Seeing this, Cao Cao narrowed his eyes and stared at the expressions of everyone in the picture.

When his son Cao Pi heard the news, he quickly lowered his head.

But the flash of resentment in his eyes did not escape Cao Cao's eyes.

Cao Zhi's face showed a confused look, but the rest of the concubines didn't react much.

The ministers were divided into two factions, those who readily agreed, and those who were skeptical of the opposition.

"Hmph, who will I leave my power to, and do I still need to wait for your consent?"

Seeing that nearly half of the people who agreed, Cao Cao relieved himself and snorted coldly.

Judging from the talent that Cao Bin is showing so far, and the future performance in the simulator, he is indeed the best candidate for the heir.

Thinking of this, Cao Cao continued to look at it.

[At the end of the month, your uncle Cao Chong died, and your eldest father was greatly saddened and grieved, and you also wept blood for it. 】

[Under your comfort and relief, your eldest father gradually accepted the reality, recovered from his grief, and ordered Cao Chong to be posthumously presented as a cavalry captain. 】

Cao Chong's death appeared in the picture again, which made Cao Cao's eyes red.

"Hey, Chong'er, I'm sorry for you."

Seeing this scene, Cao Cao felt very uncomfortable.

But fortunately, it has been simulated many times, so that Cao Cao is not as heartbroken and painful as the first time.

Moreover, Cao Bin's timely appearance also made up for the vacancy of the best successor in Cao Cao's mind.

[At the beginning of the fourteenth year of Jian'an, after repeated discussions between your father and the ministers, it was finally decided to fully implement the Quyuan plough you developed, and put this matter to you with full responsibility. 】

[After being appointed, you began to recruit troops, expand the workshop, and build it into a factory, specializing in the construction of a curved plough for promotion. 】

[Then, you personally left Xudu with a batch of freshly baked Quyuan ploughs, as well as a thousand guards who were trained halfway, and traveled all over the territory of the Han Dynasty, holding the prime minister's order, and promoting the plough with the local chief officials. 】

[But the initial effect was not great, and the people did not recognize the Quyuan plough you developed, and there were few people who could accept it. 】

[So, you have to return to your old business, recruit the people of the county, and use Quyuan plough to plough the land in public. 】

[The iron-clad fact finally made the people see the excellence of the Quyuan plow, which is far several times more efficient than the coupling plow, nearly ten times. 】

[In this way, with a point to the surface, full flowering, finally before the spring ploughing, the promotion of the Quyuan plough will be completed. 】

[Half a year later, you embarked on the journey back to Xudu. 】

The picture flickered very quickly, and it did not release all the processes of the past six months frame by frame, but only selectively played.

But even so, Cao Cao knew the process well and was shocked in his heart.

In the picture, since receiving Cao Cao's order, Cao Bin has recruited troops and horses, recruited a large number of craftsmen and apprentices, and made every effort to produce Quyuan plows.

He did not make a profit by selling the quyuan plow, but to create the quyuan plough as a sample for later promotion.

After spending three days and urgently building nearly 1,000 Quyuan plows, Cao Bin went out with this batch of divine plows that Lao Cao personally identified.

Every time you go to a place, take out a zigzag plow, plough the land in front of the people, and the rest of the matter is simple.

Leave a zigzag plough as a sample, and the local chief official will be in charge of this matter, and then let the people find craftsmen to build it themselves.

In this way, Quyuan plough spread in an all-round way at a very fast speed, and it spread throughout the entire Han Dynasty in just half a year.

"Good grandson, this is a good method."

After thinking about it carefully, Cao Cao found that there was really no more intuitive and effective way than this method.

How big is the whole territory of Dahan?

Even though Liu Bei, Sun Quan, Liu Zhang, Liu Qi, Zhang Lu, Ma Teng, Gongsun Kang and other princes occupied a small half of the territory, Cao Cao still firmly occupied most of the northern part of China, with at least more than 1.6 million square kilometers and a population of more than 8 million.

With such a large place and such a large population, it will take ten or eight years to promote a new type of agricultural tool.

But his eldest grandson Cao Bin only took half a year to do it, and did not delay the spring plowing that year.

[On the way back, you were suddenly intercepted. 】

"Huh?"

Cao Cao's face turned cold, and he was full of murderous intent.
