At the beginning, his wife came to him, and he became rich by selling kidney treasures.

Facing the emperor's questioning, Ren Hao openly admitted: "Your Majesty, this is indeed the case."

"You are so bold that you even dare to deceive my relatives!!!" Wen Yan slammed the table.

The emperor's expressionless face and hoarse and low voice made Ren Hao unsure whether he was angry or not.

After thinking quickly for two seconds, Ren Hao quickly took out the county seal from his sleeve and presented it to him, saying, "Your Majesty, please calm down."

"How can I calm down when you are so bold? How can I give an explanation to King Qinxi?" Wen Yan slammed the table again.

"Your Majesty, although the Crown Prince Qin is your relative, he is also your subject. The relationship between the monarch and his subjects is greater than the relationship between brothers."

"But the Crown Prince Qin was so arrogant and arrogant that he trespassed into the capital. This was not only a slap in the face of me, but also a slap in the face of Your Majesty. I really couldn't stand his style, so I had to punish him a little."

Ren Hao changed his plan to retaliate against Liu Chen into helping the emperor vent his anger.

"So, not only can I not blame you, but I should thank you instead?" Wen Yan took the county seal from the old eunuch.

"I just did what I should do." Ren Haoling said ambiguously, meaning that His Majesty should decide for himself whether to return the county seal to Liu Chen or send people to take over the two county cities. That was all his business.

Wen Yan was silent for a while, then waved to Ren Hao: "You can leave now."

"I'll take my leave." Ren Hao bowed and left, and his tense body and mind became relaxed.

The emperor didn't say anything else but just asked him to leave, which meant that he didn't really blame him. Instead, he might be secretly happy about it.

What does the emperor lack now besides money?

Just people.

The tax money from the two county towns may be a drop in the bucket, but men can be recruited from these two county towns and sent to the frontier front.

"Ren Sikong, please stay."

Just when Ren Hao was about to leave the palace, he was stopped by the old eunuch who caught up with him.

"I wonder what's the matter, eunuch?" Ren Hao turned around puzzledly and looked at the old eunuch who was walking over.

"Haha, it's not a big deal."

"I have been craving for that kind of grass for a long time in the palace, but I have no chance to leave the palace, and my subordinates have never been able to buy it."

"If it is convenient for you, Mr. Ren, could you sell some to me?" The old eunuch took out a gold ingot from his sleeve with a smile on his face.

However, the old eunuch's pale and gloomy face, even when he was trying to please others, looked sinister and seemed to be hiding something evil.

"You are so polite, sir."

"These are all trivial matters. When I come to the palace for the morning court next time, I will bring a pot of gold to the eunuch." Ren Hao waved his hand and did not take the gold ingot handed over by the old eunuch.

Now that he has become an official in the court, he will have many dealings with the old eunuch in the future. Rather than accepting money, it is better to accept favors from him.

Who knows, maybe the old eunuch can help me in the future.

"Then I would like to thank Sikong Ren first." The old eunuch nodded tacitly, then smiled and saw Ren Hao off from the palace.

After Ren Hao left the palace, he did not go back home directly, but ran outside the city, found a rotten yellow mud ground, and started digging.

He scooped up a few handfuls of yellow mud and put it in his pocket before returning home.

Before he entered the palace, Li Shiji told him to borrow a few people from the palace when he returned.

The so-called excerpter is the person who records excerpts. After all, printing had not yet appeared in this era, and the excerpter was a walking printing press.

However, because he was too cautious when meeting the emperor, he forgot about borrowing the person.

So he decided to scoop up some yellow mud and take it back with him to deal with the situation.

At this time, Shen He and Li Shiji were discussing the content of the test questions in the study room in the mansion.

"Brother Ren, where is the person you are looking for?"

Seeing Ren Hao coming back with the rotten yellow mud, Li Shiji was stunned.

“This is picking people.”

Ren Hao put the rotten yellow mud on the table, which made Li Shiji and Shen He laugh and cry: "Mr. Ren, this joke is not funny at all."

"That's it."

"Could it be that you know some witchcraft and can just make a few clay figures and ask them to help us copy down the questions?" Li Shiji said helplessly.

"Although I don't know how to do witchcraft, I know how to do magic."

"You will use chopsticks to carve the questions on the clay tablet, and leave the rest to me."

Ren Hao molded the mud into a square shape and handed it to the two of them.

Although Li Shiji and Shen He had no idea what Ren Hao was saying, they still followed his instruction and carved the questions into the clay tablet with chopsticks.

The two of them asked a total of five questions.

Ren Hao looked at the clay tablet and recalled modern math test papers, so he asked, "Aren't the numbers you gave too few?"

"Mr. Ren, the quality of the questions is not the quantity. These five questions were carefully and cleverly designed by Minister Li and I." Shen He explained.

Li Shiji beside him also nodded and promised: "I can guarantee that there will be no more than ten people who can solve all five problems."

"Okay then." Ren Hao looked at the clay tablet and nodded. Although the questions on it used words instead of numerical formulas, he still couldn't understand it.

Anyway, he just made rubbings.

Ren Hao poured all the ink into the clay tablet, and then placed pieces of paper on it one by one.

Every word for the topic on the clay tablet was copied onto the paper.

This shocked Li Shiji and Shen He who were standing by. They had never thought that it could be done this way.

"Mr. Ren is indeed a remarkable man in the world. This method is wonderful." Shen He gave Ren Hao a thumbs up with some suspicion of flattery.

Li Shiji, who was standing next to him, was also extremely surprised.

He has traveled around the world for many years and has broadened his horizons, but this is the first time he has seen such a practice.

"Brother Ren, did you think of this or learn it from somewhere?" Li Shiji asked curiously.

"This method is called the art of rubbing. I learned it from an old gentleman when I was traveling." Ren Hao proudly began to make up stories again. He couldn't tell the two that this art of rubbing was something he learned in his previous life.

Then, Ren Hao dipped his index finger in ink and wrote the characters on the table.

"What is this word?" Shen He and Li Shiji both felt unfamiliar with it. It was the first time they saw this word.

"This word is called Tuo. Which old gentleman invented it?" Ren Hao taught the two people to recognize this word and how to use the technique of rubbing.

The world of this era is different from the previous life. The rubbing technique of the previous life was the earliest printing technique, which was invented during the reign of Emperor Ling of the Eastern Han Dynasty.

The rubbing technique of this period did not exist before Ren Hao brought it out. It all relied on people to copy and record one stroke at a time, which was time-consuming and laborious.
