Li Guanyun, this unusual patient, might not be treated by Su Fan.

Making a Martial Arts Grandmaster become paralyzed is something he doesn't want to get involved with; perhaps he doesn't even have the ability to manage it.

Li Guanyun looked at Su Fan and said unhurriedly: "Divine Doctor Su, can you cure my illness?"

Su Fan shook his head: "I cannot cure your illness, Mr. Li. You'd better find someone else more capable."

Upon hearing this, Li Guanyun was not angry.

He continued: "Divine Doctor Su, let me tell you the whole story first, and then you can consider whether to help me with my illness, alright?"

Su Fan was actually reluctant to get involved in this matter, but since the other party wanted to reveal such secrets to him, he was still willing to listen.

Someone able to paralyze Li Guanyun, a Martial Arts Grandmaster, could use the same means against him.

After listening, he could make early preparations.

After Su Fan nodded, Li Guanyun did not immediately speak about the matter but instead asked: "If Divine Doctor Su is willing to take action, can you heal my injury?"

Su Fan was silent for a moment, then nodded slightly.

Although Li Guanyun was already paralyzed, the main issue was nerve damage.

Compared to Li Guanyun, Tian Yangguang still looked quite lively, but his injuries were far more severe.

It was just that Tian Yangguang's nerves were undamaged, so he didn't end up like Li Guanyun, confined to a wheelchair.

Li Guanyun did not hesitate this time and asked Su Fan another question: "Divine Doctor Su, have you heard of hidden families?"

Su Fan was slightly taken aback; he indeed hadn't heard of this.

But he understood, it must be something very advanced, otherwise he wouldn't have remained uninformed until now.

Su Fan didn't pretend to understand but simply shook his head.

Li Guanyun wasn't concerned either and said after Su Fan shook his head: "Hidden families are clans established by ancient alchemists."

Upon hearing this, Su Fan could only gasp.

Even those well-known business families across the world have only a couple of hundred years of history.

If hidden families are clans established by ancient alchemists, then even if they were founded in the Qin dynasty, they have developed for over two thousand years by now.

A company that operates for several decades might become a giant in its field.

What concept then does a family that has developed for over two thousand years suggest?

The wealth and treasures they've accumulated are almost unimaginable.

The number of experts within the family must be astonishingly high.

Seemingly understanding Su Fan's thoughts, Li Guanyun immediately said:

"Most of these families were founded before the Qin dynasty, but they also experienced interruptions in the river of history."

"But as long as the family's descendants aren't completely wiped out."

"After disappearing for dozens or hundreds of years, they might develop once again."

Even after Li Guanyun explained, Su Fan still understood.

These hidden families are all time-honored gigantic entities.

Whether it's the Palea family or the Kawabata family from Japan, they are nothing compared to these hidden families.

At this time, Li Guanyun dropped another bombshell on Su Fan.

"My original surname is Wu, and I am the direct descendant of the hidden Wu family in Shu."

"The current people controlling the hidden Wu family in Shu were once merely our family's servants."

This matter reminded Su Fan of the historical story of the Tian family replacing Qi.

Li Guanyun's enmity with the hidden Wu family in Shu might be similar.

However, Su Fan really isn't interested in getting involved with such matters now.

He can only say: "Mr. Li, I am merely a Martial Artist in the Gang Qi Realm; I don't want to interfere in this matter."

Although he's a Martial Arts Grandmaster, apart from Ye Zhaoyi, clearly nobody else knows about it.

Unless he encounters an unavoidable situation, he plans to lay low and strike when necessary for a long period.

After Su Fan spoke, Li Guanyun smiled and said: "Divine Doctor Su, this matter is actually not as difficult as you think."

"There are two branches within the Wu family's direct line, and we have already reached a collaboration."

"I just wish for my strength to be restored before taking back what belongs to me, to gain more benefits."

"If this succeeds, I can give Divine Doctor Su the first sixteen volumes of the Qihuang Medical Classic."
