“Master, you know that I can’t leave you,” Yu Zheng Xi said quietly.

To be honest, Yu Zheng Xi himself was no longer young. He’s basically the oldest among the disciples under Traveling Doctor Liu and his body function was no longer as good as when he was young.

But because Yu Zheng Xi practiced martial arts and even be the sword of others for a while, he was still capable of protecting Traveling Doctor Liu when it was necessary.

“Indeed…” Traveling Doctor Liu sighed when he heard Yu Zheng Xi’s words. But he was not surprised in the slightest bit because he had expected it to be like this.

For his disciples, their master is the most important.

Of course, that was after putting aside their own family and so on.

But for Traveling Doctor Liu, he cared for his disciples greatly and hoped that all of them would be able to stay save and life well.

“Master, I don’t think General Yang will allow Eldest Senior Brother to be involved in the war,” Yu Zheng Xi said quietly.

No matter what, Shi Hao Yi is just a doctor. Who would want to let a doctor wield a weapon and fought on the battlefield?

Besides, Shi Hao Yi was not young anymore.

It was not realistic for him to fight.

“I know, but there might be people who target the medical personnel on the battlefield. Because without the support of the food supplies and also the doctors who could treat you on the battlefield, there’s no way a war could be fought,” Traveling Doctor Liu said calmly.

Yu Zheng Xi was stunned and he looked at his master in surprise. “Master, I don’t know you understand the art of war.”

Traveling Doctor Liu rolled his eyes. “I don’t understand the art of war. But I know more than enough that having weapons in hand is not enough to win the war.”

If one didn’t have enough brains and other resources, there was no way they could win the war.

After all, Traveling Doctor Liu himself had participated in various wars when he was young to earn the remuneration. Because of his stance of not siding with any kingdoms, these generals all knew that Traveling Doctor Liu would help them as long as they paid him.

And these money would be used by Traveling Doctor Liu to buy more herbs and study medicine.

For Traveling Doctor Liu, his study would never end.

Even until now, if it was possible, Traveling Doctor Liu really wanted to study more herbs and so on.

For this reason, there was still a medicinal garden on the back and Traveling Doctor Liu would give lecture to Shi Hao Yi’s disciples from time to time. Only in this way would Traveling Doctor Liu not be bored to death while he was staying in Shi Hao Yi’s clinic.

“I see.” Yu Zheng Xi nodded.

His identity in the past allowed him to learn these things and Yu Zheng Xi himself didn’t think that it was anything strange. Anyway, he knew very well that these were important for survival in this war ridden world.

“How’s your junior sister’s situation lately?” Traveling Doctor Liu stopped thinking about Shi Hao Yi and asked another question.

“She’s doing well, Master,” Yu Zheng Xi replied without hesitation. “The restaurant that she opened has been quite popular. There are some people who made troubles from time to time, but she can deal with it.”

“You don’t help her?”

“I don’t have that obligation.”

Traveling Doctor Liu shook his head helplessly but didn’t force Yu Zheng Xi to do anything.

Regarding the relationship between Yu Zheng Xi with those three, Traveling Doctor Liu was very clear. Even though they all lived nearby for a period of time, but Yu Zheng Xi was much older than them and didn’t have the same interest towards medicine.

For Yu Zheng Xi, learning medicine was something that was necessary for his survival.

The others wanted to learn medicine so that they could save others.

The interest was different and the age was not that close,

In this way, Yu Zheng Xi was not very close to Qi Xue and the other two. They only knew each other better simply because they lived close enough.

But that was in the past.

Now that they were living nearby once again, Yu Zheng Xi still didn’t have much interaction with the others.

“I thought that you will be closer with Qi Xue because you traveled with her for around a year before meeting with those princes,” Traveling Doctor Liu said helplessly.

Traveling Doctor Liu met with Qi Xue in Shi Long Kingdom’s territory.

At that time, Qi Xi Kingdom’s territory was vast and it was easy to cross the land from Shi Long Kingdom to Qi Xi Kingdom.

Around a year after her meeting with Traveling Doctor Liu, they met with their two junior brothers. And it was also during that one year that Yu Zheng Xi had the chance to have more contact with Qi Xue.

That was if he wanted it.

“No.” Yu Zheng Xi shook his head and said, “I’ve never been close to her.”

He could still remember the girl whom Traveling Doctor Liu picked up. To be honest, he seriously doubted whether his master had the hobby of picking people up. He didn’t even know whether Qi Xue had any medical skills or any talent related to medicine and picked her up directly.

It could be said to be the most bizarre case in Yu Zheng Xi’s eyes.

When Traveling Doctor Liu picked Yu Zheng Xi up, there was still traces of medicine in Yu Zheng Xi’s hand because he treated himself. With no one else to ask for help and countless people still chasing him from behind, Yu Zheng Xi could only treat himself and the smell of medicine was very strong.

It would not be an exaggeration to say that he should have some talent for medicine from that alone.
