People in the Qin Dynasty, entertained during the Warring States period

Although the technique was crude, it was extremely useful and efficient.

However, I need my younger sister's cooperation.

After Li Yuan left, Zhu Ying, who had been waiting outside the hall, entered the hall.

As a retainer of Lord Chunshen, Zhu Ying always performed his duties diligently.

"My lord, Li Yuan has been secretly raising assassins for some time now, which may be for ulterior motives."

Lord Chunshen, Huang Xie, said: “I know. Li Yuan told me that because the king is seriously ill, the Qu, Jing, Zhao and other families are making trouble. He is worried that someone will harm him, so he has raised some thugs and asked me for some manpower.”

Zhu Ying frowned, sensing that something was amiss.

If there is any concern about Qu Jingzhao's family, Li Yuan, with his power, could simply temporarily deploy some elite troops as guards.

Compared to those desperate criminals, the Imperial Guards were undoubtedly more reliable.

But he couldn't figure it out either, so he could only remain silent and agree.

On the other side.

Cao Ze had just secretly met with the head of the Luowang organization in Chu capital.

It's ridiculous.

This person in charge has now been recruited as a loyal follower by Li Yuan.

Or rather, the upheaval in the Luo Wang organization a few months ago led many of its members to go into hiding, abandoning their Luo Wang identities and becoming outlaws and assassins once again.

They don't have the true loyalty to die for Luo Wang. Even their leader's leader, Lü Buwei, is finished. If they don't carefully observe the winds of change, they might be reduced to nothing but dust.

Then they encountered Li Yuan secretly recruiting desperados. Many members of Luo Wang, looking for a new home, even used their skills to infiltrate Li Yuan's elite group.

The perfectly good plan of raising assassins had turned into raising Luo Wang killers without even Li Yuan's knowledge.

Cao Ze wore a smile, even though he seemed to find it both funny and absurd.

Perhaps only he knows what Li Yuan is doing with all those desperate thugs.

It's a bit funny, though, that Li Yuan recruited only assassins from the Luo Wang organization, and even brought in the person in charge.

What's this? No background check?

Of course, he just laughed it off.

They had no intention of interfering in the internal affairs of Chu.

It is foreseeable that after Li Yuan succeeds as it has in history, the Chu Kingdom will be embroiled in internal strife.

"Your Excellency, the head of the medical school requests an audience."

A Qin soldier reported this from outside the door.

Cao Ze went out and came to the front yard of the post station.

Two beautiful women, one tall and one short, were standing in the courtyard admiring the plum blossoms in the corner of the wall.

The plum blossoms are in full bloom right now.

"The edge of the sword comes from sharpening, and the fragrance of plum blossom comes from the bitter cold."

Nian Duan spoke softly and leisurely, saying, "Rong'er, the path of medicine is vast and boundless. Never slack off. Only through diligent study and practice can you achieve something."

Duanmu Rong raised the corner of her eye slightly and caught a glimpse of Cao Ze out of the corner of her eye.

"Master, he's here..."

Nian Duan had no choice but to abandon her idea of ​​continuing to educate Duanmu Rong, and turned to Cao Ze to bow, saying, "I'm sorry to have bothered you, sir."

Cao Ze smiled and said, "It's damp and cold outside, let's go inside."

Winters in the South are not as cold as those in the North, but compared to the dry cold of the North, the damp cold of the South is also extremely torturous, especially in this era without air conditioning to dehumidify.

"Respect is not as good as obedience."

Compared to the aloof and cold-hearted Duanmu Rong, Nian Duan was polite and courteous from beginning to end, much like a rigid old-fashioned person. If she were also devoid of humanity and devoid of emotions and desires, she would definitely be a Warring States version of Abbess Miejue.

One man and two women entered a small room.

"Master Nianduan".

"Sir, please speak."

"The soul is inherently mysterious, and for a master to advance to the level of a grandmaster, with the essence, qi, and spirit united as one, recovery is not something that can be achieved in a day or an hour, and..."

"And what?! I've already written the letter and sent it to Jinghu Medical Clinic, you're not going to be helpless again, are you?"

Cao Ze glanced at the charming and lovely Rong'er, paused, and said, "There is a way, but it requires me and the master to cultivate our souls together for many days."

"what?!"

Duanmu Rong was struck dumb, frozen in place like a puppet, her mind blank.

Nian Duan, having weathered many storms, remained calm and unmoved by Cao Ze's words.

"Sir, is there any basis for your statement?"

Nian Duan knew many secret techniques and secret arts that were unknown to others. As a master of medicine, he was naturally very clear about minor arts such as bedroom arts.

However, I have not yet heard of any method of cultivating both the spirit and the soul that can compensate for the deficiencies of the spirit and the soul.

Duanmu Rong came to her senses and looked at Cao Ze with a complicated expression.

Is Cao Ze really that kind of person?

Taking advantage of people in distress? She even preyed on her master? What a beast!

Cao Ze was unaware that Duanmu Rong had relegated him to the realm of animals.

Otherwise they would definitely cry foul!

He slowly said, "Taoism believes that 'the spirit governs the light, and the soul governs the darkness,' so the spirit and soul should be like yin and yang, and need to be in balance."

"Master Nian Duan caused his soul to dissipate due to his forceful attempt to become a Grandmaster. The root cause was that the 'spirit' flower among the three flowers of 'essence, qi, and spirit' was insufficient. And the lack of 'spirit' will cause an imbalance of yin and yang."

"Therefore, in order to prevent Master Nian Duan's soul from dissipating and to restore it to its original state, a specific secret method is needed to form a 'Yin-Yang cycle,' and in the repeated cycles of Yin and Yang, the 'two spirits harmonize and transform into a child' can be achieved."

"In short, we are each other's furnace and vessel, using the principle of Yin and Yang to allow our souls to be reborn continuously in a short period of time..."

Cao Ze spoke at length, recounting everything in great detail.

He believed that with his insight, Nian Duan would be able to discern whether something was feasible.

Duanmu Rong, standing to the side, was completely dumbfounded.

What about dual cultivation of spirit and soul, what about using each other as a furnace or vessel...?

Isn't it about going to bed?

Nian Duan's expression gradually changed from strange to thoughtful.

After a long silence, Nian Duan said, "What you say makes sense..."

She glanced at Duanmu Rong and said, "Rong'er, why don't you go out for a moment?"

She is not one to shy away from medical treatment. As the head of a medical school, she would never shy away from medical treatment. The story of the medical master Bian Que meeting Duke Huan of Cai is even written in the book "Han Feizi".

Duanmu Rong was reluctant, but she could not disobey her master's orders, so she had no choice but to go out.

As she closed the door, Duanmu Rong stared wide-eyed at Cao Ze, her lips moving slightly, as if to say that if Cao Ze dared to defile her teacher, she would kick the door and fight to the death.

After Duanmu Rong left, Nian Duan took a deep breath and said, "I have learned a little about the dual cultivation of spirit and soul that you mentioned in medical classics."

Cao Ze hummed in agreement, signaling Nian Duan to continue.

Nian Duan said, "What you say is certainly true, but our ancestors recorded in the classics that those who have cultivated their souls together will develop a special emotional connection. I wonder if this is true?"

As Cao Ze recalled the scenes of the Black and White Sisters gradually falling in love with him, he felt somewhat uncertain.

"It may or may not, I'm not sure. But I can tell you, Master, that during dual cultivation of the soul, one will not be able to see each other's secrets."

Cao Ze pondered for a moment and said, "There's one more thing."

"Because the master's soul has been scattered for many years, there will be some risks during dual cultivation, which may lead to a drop in cultivation level, or may lead to... the soul shattering and spreading out prematurely, resulting in ascension to immortality."

"...Is the risk high?"

"Not high, one in a hundred."

Nian Duan remained silent for a long while, then chuckled self-deprecatingly, "I never thought that an old maid like me would have to engage in dual cultivation with a man before I die. It's fate..."

Cao Ze was surprised; he hadn't expected Nian Duan to still be a virgin.

There are quite a few virgins in Qin's Time.

For example: Gai Nie, whose heart is only for the world; Wei Erha, whose heart is only for his senior brother; Ban Laotou, who only loves mechanical arts; and Gao Jianli, the high-speed rail duo who are devoted to love throughout their lives...

But old maids are a rare find.

It seems that only the sister-in-law, the Moon Goddess, and the stubborn Grand Master of Fate are left.

Well, it's okay. He'll try his best to help them in the future and give them more encouragement.

"...Do I need to take more off?"

Nian Duan's beautiful face flushed slightly. She clutched her flaxen coat, which she had already taken off, and was only wearing white silk underwear.

Compared to the bikini that Li Wuyan Lingji likes to wear, Nian Duan is much more conservative. Her clothes are long and are almost identical to what she wears outside, except for the difference in material thickness.

Having seen it all before, Cao Ze wasn't overly agitated.

He didn't say anything, but simply took off his clothes until he was only wearing shorts, which made Nian Duan's eyes dart around.

"Clothes should be as minimal as possible. When cultivating both the soul and spirit, I can't perceive much soul power; I can only rely on my naked eye to distinguish it."

Cao Ze paused for a moment and said, "Of course, it's not mandatory. If you mind, Master, you don't have to take it off. However, I can't guarantee that the risk won't increase."

"……Um."

Nian Duan sighed slightly, glanced at Cao Ze's strong body, and a strange light flashed in her beautiful eyes.

Without further hesitation, she took off all her clothes and was left naked in the damp, cold southern air.
