Yagyu Kaori wanted to ask how Su Fan would handle the shell left behind by the Yagyu family.

Or rather, the related interests left behind after the Yagyu family's downfall.

This question was something Su Fan hadn't thought about.

His plan was to take out his enemies and leave; the matters in Japan were beyond his reach, and he couldn't manage them.

Yagyu Kaori asking this question now had indeed stumped Su Fan.

After thinking for a moment, he could only pass the ball back to Yagyu Kaori: "What do you think should be done?"

So far, Yagyu Kaori and Chen Mengfei should be the two smartest women Su Fan had encountered.

Chen Mengfei was exceptionally capable and had unique insight, while Yagyu Kaori was insidiously cunning.

If Yagyu Kaori were his enemy, she should, of course, be swiftly eliminated.

But if Yagyu Kaori were his woman, she would be a precious asset.

Yagyu Kaori had seriously considered how to handle the business left behind by the Yagyu family.

She looked at Su Fan and said very earnestly, "I can stay in Japan and manage the Yagyu family's business for you."

Her staying in Japan would mean that Su Fan's control over her would significantly weaken.

It depended on how much trust Su Fan had in her and whether he was willing to let her stay in Japan.

Su Fan shook his head: "You can't stay in Japan; you're not a Martial Artist, so you don't have the ability to protect yourself there."

"As for the Yagyu family's business, it's best to find an agent, and you can remotely control them from China."

What Su Fan said made sense, so Yagyu Kaori did not object.

Although she had ways to protect herself, she was ultimately not a Martial Artist.

After the fall of the Yagyu family, continuing to stay in Japan posed certain risks.

Yagyu Kaori sighed, "If you have a way to completely control Yagyu Zhengren."

"Then Yagyu Zhengren could be your spokesperson in Japan."

"He wasn't involved in the Zhao family's extermination."

"He is a late-stage Gang Qi Realm Martial Artist and has received recognition from the Fujimura Sword Saint."

"Among all the people I know, he is the best candidate."

Hearing this, Su Fan fell into deep thought.

Because in the thirteenth volume of the Qihuang Medical Canon he acquired, there were some special prescriptions.

One of the prescriptions was called the Ying Sheng Worm Prescription.

After taking this prescription, Yagyu Zhengren would be under his control.

However, getting Yagyu Zhengren to take the Ying Sheng Worm Prescription wouldn't be easy.

No matter how negligent Yagyu Zhengren was, he wouldn't give him a chance to poison him.

After pondering for a moment, Su Fan decided to bring up the matter of the Ying Sheng Worm Prescription.

"In the Qihuang Medical Canon volume you gave me, there is a prescription called the Ying Sheng Worm Prescription."

"But, Yagyu Zhengren would certainly not give us an opportunity to poison him."

Yagyu Kaori immediately shook her head and said with some excitement, "We have a chance!"

Saying this, she took out her phone and showed a photo to Su Fan.

"He has a chronic illness and needs to take this kind of pill long-term."

"Can that prescription you mentioned be made to look like this type of pill?"

Su Fan looked at the black pill in the photo and then nodded: "Yes, but we need to find a pharmaceutical factory."

Yagyu Kaori smiled and said, "Leave it to me."

Su Fan had no strong opinions about Japan, as his understanding of Japan was very limited.

Now that such a godsend opportunity presented itself, he certainly wouldn't miss it.

He wanted to develop Oriental Medicine into a multinational pharmaceutical giant and have a presence worldwide.

Su Fan quickly realized that Yagyu Kaori was an extremely intelligent, meticulous, and exceedingly careful woman.

Because Yagyu Kaori had already started asking, "Does the Ying Sheng Worm Prescription have a unique smell? Can it be perfectly made into the pill in the photo?"
