Because Sun Simiao wanted to treat Li Er, Li Er asked Zhang Nan to return home first. However, before Zhang Nan left, Li Er gave Zhang Nan a handwritten order to supervise Zhang Nan, and could build a military academy according to his own ideas.

Zhang Nan's goal has been achieved and he is unwilling to stay in the palace for too long, so he happily returned to the mansion.

As soon as he entered the mansion, Su Wen ran over to report that Lord Du Ruhui had been waiting in the mansion for a long time with his second son.

Zhang Nan was wondering why Du Ruhui brought Du He to his mansion. He guessed that he might have brought Du He to the door to apologize, so Zhang Nan quickly walked to the front hall to see what Du Ruhui came here today.

When he walked into the front hall, Zhang Nan bowed and said, "Hello, Lord Du, why did you come to my house today if you have time?"

"Hey, what happened a while ago made Qingquan laugh, so today, I came to the door with this incompetent rebel son to apologize. I hope Qingquan will be more tolerant." Du Ruhui also stood up, bowed his hand, and said truthfully.

"Mr. Du is so polite. It's a small matter. It's mainly because Huai Mo didn't break Du He. I think Huai Mo was very heavy on that day." Zhang Nan said with a smile. Although Cheng Huai Mo is still not as good as Cheng Yaojin now, an old punch is not something that Du He, a slutty boy, can bear.

"Hey, no, let Qingquan laugh, you are so angry, why don't you come and apologize." After Du Ruhui said that, he called Du He who was standing aside and asked Du He to apologize to Zhang Nan.

What Zhang Nan didn't expect was that Du He changed his previous appearance and his cynical temperament had also faded a lot. Instead, he respectfully bowed to himself and said: "Master Zhang, it was my fault some time ago, but I was too reckless. After the last incident, I learned from my mistakes and felt very sorry for my father. So I decided to change my heart and live a new look."

At first, Zhang Nan was still very happy to hear it. After all, the prodigal son turned around and was not worthy of gold, but Zhang Nan suddenly thought of something.

"Wait, what are you calling me?" Zhang Nan asked with a strange look on his face.

"Master Zhang." Du He said in a humble and arrogant manner.

"Master Zhang? When did I accept you as a student?" Zhang Nan asked in surprise. Did he take drugs and would he have hallucinations? This is Zhang Nan's first thought.

"Hey, Qingquan, I know you are a talented person. Qinglian is stupid by nature. I only hope that Qinglian can have the ability to settle down in a hundred years." Du Ruhui interrupted at this time.

"Yes, Master Zhang, just accept me. I, Du He, are willing to worship under the time travel sect. Even if I just stay by Master Zhang as a servant who serves tea and water, I will be satisfied." Du He said with a sincere face.

Facing such sincere Du family and son, Zhang Nan looked constipated. It’s not that Zhang Nan disliked Du He for being an ignorant and ignorant young man, mainly because he had nothing to teach Du He and could not even recognize words. How could he teach others? He couldn’t teach Du He to learn how to use the system, and Du He didn’t have it either.

Seeing that Zhang Nan was unwilling to accept him as his apprentice, and he looked constipated, Du He said, "Please accept me as his apprentice." After that, Du He seemed to have already thought about it and knelt down immediately, which scared Zhang Nan.

Not to mention the identities of the two, Du He, as a young man of the same age as him, was able to make such a determination. It seems that he really wanted to make a change, but Zhang Nan really had nothing to teach Du He, so he quickly said, "Get up first and talk first."

Zhang Nan still felt that she could not accept Du He kneeled down, so she had to let Du He stand up first.

"No, if Master Zhang doesn't agree, then I won't get up and kneel here forever." Du He looked disbelief and tried, which made Zhang Nan feel completely useless.

"Okay okay, I agree. You stand up and talk first." Zhang Nan had no choice but to say so.

When Du He heard this, he stood up and said with a smile: "Thank you, Master Zhang."

Du Ruhui smiled and stroked his beard, saying, "Qinglian, since that's the case, we must study hard with Qingquan in the future."

"Children follows his father's teachings." Du He turned around and said to Du Ruhui.

"Qingquan, since you have agreed to accept Qinglian as your disciple, then you have to prepare for this ceremony of apprenticeship." Du Ruhui said.

When he heard that there was a ceremony of apprenticeship, Zhang Nan was so angry that it was so troublesome to be a disciple.

"This, Lord Du, I really don't know what to do with this apprenticeship." Zhang Nan had to tell the truth. Although Zhang Nan didn't know the ancient apprenticeship ceremony, Zhang Nan still knew the relationship between the master and the apprentice.

The traditional master-apprentice relationship is second only to the father-son relationship, which is the proverb that "those who gave birth to me are parents, and those who taught me are masters", and "returning to a teacher is like reincarnation". Zhang Nan dared not neglect such an important relationship.

"Oh? Qingquan didn't know the ceremony of apprenticeship. Then how did Qingquan worship the master at that time?" Du Ruhui asked strangely.

"This is what we travel through time and do not pay attention to these common etiquettes. Just focus on learning." Zhang Nan said casually.

Du Ruhui frowned after hearing Zhang Nan's narrative. After all, this apprenticeship is a major event in life. Du Ruhui is also a famous family in the Tang Dynasty. If his son wants to be a master, he will not even have a tribute to apprenticeship. If he spread it, it will not only be shameful, but also be unreasonable.

Du He was actually very happy that the master he worshiped was indeed different. He was even a maverick. Du He himself thought that these common etiquettes could be avoided, but it was just because his father was there, so it was hard to say.

"Let's do this, Qingquan, let me leave this ceremony of apprenticeship. Qingquan, you only need to attend." Du Ruhui thought for a while and said.

Du Ruhui said this, and Zhang Nan had no choice but to nod and agreed.

"By the way, you have to prepare some clear springs in advance." Du Ruhui seemed to remember something and reminded him.

"I don't know what I'm going to prepare?"

"Well, Qingquan, you have to prepare a portrait of your ancestors traveling through time. You also have to prepare gifts such as onions, celery, etc. You can just prepare these. By the way, most masters will give them to their disciples "The Analects of Confucius", but Qingquan is not a Confucian school. As for what books to give back, you have to consider yourself."

When Zhang Nan heard this, he felt a little overwhelmed. All the other things were ready. However, Zhang Nan really didn't know who to look for the portrait of this ancestor, and he didn't know who was the first person to travel through time.
