Three Kingdoms: At the beginning, Diao Chan came to the door with her daughter.

Because I have to explain the principles of floor heating and air conditioning to the craftsmen.

And the specific process of how to implement these two systems in architecture.

Han Yi spent almost the whole morning before he managed to get it done!

When he was smiling and preparing to take over Ying Bao's teaching.

Sudden!

The back figures of the two adults appeared in his eyes.

One is very familiar, it is clearly Cai Yong!

The other one has gray hair and sits upright.

Han Yi didn't recognize it. but......

Someone who can keep Cai Yong company.

Han Yi could figure it out even with his toes.

If it’s not Zheng Xuan, who is it?

"Everyone Cai!"

"Mr. Zheng!"

"Why are you two here?"

Han Yi took a look and walked behind the two of them and lowered his voice.

"Oh, of course I am listening to the class."

Zheng Xuan didn't feel the slightest bit embarrassed and answered calmly.

Wu Cao!

Attend the lecture?

Stop joking.

Who in this world dares to give lectures to you two?

"Mr. Zheng, you really shame Han. Han

Yi bowed his hands hurriedly and tried to ask the two of them to leave:"Mr. Zheng, Mr. Cai, how about we talk in the study?""

If this spreads out, outsiders will definitely not say anything wrong with Ying Bao. Instead, they will say that Han Yi is ignorant.

After all, Ying Bao is just a child, but you, Han Yi, don't you know who Zheng Xuan is?

Good guy!

Dare to teach Zheng Xuan.

Does your kid have horns on his head or a tail on his back? This is totally wrong!

But what about Zheng Xuan?

He seems to be reluctant to leave!

He frowned and didn't want to leave for a long time:

"Sheriff Han, can we wait any longer?"

"I haven’t finished learning this pinyin method yet!"

"What's the matter? Let's talk about it later. I wonder what Governor Han thinks?"

Damn it!

It turns out that he is greedy for his own pinyin method!

Han Yi did not hesitate and waved his hand:"Isn't it just the pinyin method? Isn't it okay if I give Zheng the same set of teaching materials? Let's leave quickly. If this spreads out, what will the world's scholars think of me?"

"this......"

Zheng Xuan pondered for a long time and nodded:"Okay!"

The two of them got up and followed Han Yi to the study room in the inner courtyard.

Han Yi took the main seat.

Zheng Xuan and Cai Yong were seated separately.

After Han Yi briefly exchanged greetings, he turned to the main topic.

"That was what happened that day."

There is no other way, Han Yi can only spread his panic again:"Cai people said that person is Shen Nong's sage. I don't know this, but my Taishan has indeed been greatly improved by this person."

"Shen Nong appeared as a saint? Zheng

Xuan pinched a lock of beard under his chin and exhaled a long breath:"Now all kinds of evidence point to Shennong, especially what happened in Mount Tai!""

"That's right!"

Cai Yong nodded affirmatively:"I have the same intention as Wen Ju. We must decipher the will left by Shennong. There may be secrets that can help the people of the world!"

"Unfortunately......"

Having said this, Cai Yong shook his head:"Except for the word Shennong, I don't recognize any of the characters on that tortoise shell. I have no choice but to ask Mr. Zheng for advice."

"this......"

Zheng Xuan frowned and said softly:"To be honest with you, I don't know any of the other fonts except Shen Nong!"

"ah?"

Cai Yong was surprised:"Why, even Mr. Zheng?......"

Zheng Xuan nodded:"I really don't know, but there are some rubbings of ancient scriptures in my house. Maybe after searching and comparing them, we can get some clues!"

"So, Mr. Zheng is planning to go back?"

Cai Yong leaned forward and tried to ask

"That was the original plan! Zheng

Xuan smiled calmly, then turned to look at Han Yi and bowed his head:"Governor Han, I have come here with a merciless request. I hope you can allow it!""

"Mr. Zheng, please don’t say that. Han

Yi returned the gift and said without hesitation:"If you have anything to do, you might as well just say it!" If Han can achieve half the goal, he will naturally not refuse. Even if it cannot be done, we will try our best to make it happen!"

"good!"

"The old man said it directly. Zheng

Xuan let out a long sigh and said:"To be honest, when I left Beihai, I got the exact news that the Yellow Turban bandits defeated by Gongsun Zan are coming to Qingzhou!""

"If nothing unexpected happens!"

"In ten months at most, this band of Yellow Turban bandits will inevitably invade Beihai. The old man will hold lectures in Beihai, with more than a thousand disciples and tens of thousands of books in his mansion. Once he encounters the Yellow Turbans, the consequences will be disastrous!"

"ah? Is this happening?"

Cai Yong was stunned when he heard this.

Millions of Yellow Turbans are raging, and Qingzhou will be completely barren! And his private school has no ability to resist. If it suffers from the Yellow Turbans, it will be destroyed!

"yes! Zheng

Xuan nodded affirmatively:"I originally wanted to evacuate the disciples and hide alone. After the Yellow Turbans are completely gone, I can start teaching again. But now, I feel that if I can come to Mount Tai, I won't be afraid of the Yellow Turbans."" hiss~~~

Cai Yong couldn't help but gasped:"Mr. Zheng, do you want to move all your disciples to Mount Tai?"

Zheng Xuan raised his hand and said,"I wonder if Commander Han is willing to take them in?"
