The method for refining Jiang Chen Grass is known to very few people, and requires extremely skillful hands.
Otherwise, it is practically impossible for anyone to achieve it.
The reason why Jiang Chen Grass has always appeared in Dragon Country's black market, aside from its price attracting many unscrupulous merchants, is more so because its demand is increasing year by year.
However, with its price tag, ordinary people would not and could not afford to buy it.
Those who did purchase it were usually for the purpose of poisoning.
Or...
There is no second possibility.
Within the black market, there should also be poison doctors specifically responsible for refining such poisons.
Of course, Zhou Yu has not been to the black market in a long time, so this last part is purely conjecture.
"Dad!"
Upon hearing Zhou Yu say that if the old man were not poisoned, he might be able to stand up again, Su Qichuan could no longer hold back his emotions.
He sobbed uncontrollably.
Su Xingyang also knelt by Old Master Su's bedside.
Su Yuyan was filled with regret.
Over the years, she had been the closest to her grandfather. Her second uncle and cousin had no choice, but she, who had the opportunity to discover it, had never noticed any clues.
If not for this, grandfather wouldn't have...
"I'm sorry, Grandpa, it was my negligence. If I had noticed earlier, you wouldn't have suffered so much," Su Yuyan said, tears streaming down her face.
Her makeup had long since run.
At this moment, it looked somewhat comical.
Old Master Su comforted them, "What are you all doing? Am I not dead yet? Besides, I myself couldn't detect the poison in the medicine, so how could you? And, isn't Zhou Yu here?"
Right!
Zhou Yu!
Zhou Yu must have a way to help grandfather stand up again.
Su Yuyan turned around and quickly asked Zhou Yu, "Zhou Yu, do you have a way to help Grandpa stand up again?"
"Regarding this, I cannot be one hundred percent certain, but if I were to personally intervene, the success rate would be about seventy percent. Your grandfather's body is currently very weak, and that thirty percent chance of failure is unavoidable," Zhou Yu stated truthfully.
"Seventy percent! That's enough!" Old Master Su exclaimed with joy.
In fact, during the short time Old Master Su spent with Zhou Yu, he had not asked his grandson-in-law if he could cure him.
Because in Old Master Su's eyes, it was like a dream.
Over the years, other old men would sleep at night, spend their days with family, eating, chatting, and even playing with their great-grandchildren.
But he?
He could only lie on the bed, staring at the ceiling day after day.
Due to his poor immune system and susceptibility to illness, he couldn't even ride a wheelchair out for a stroll, nor could he play chess with old friends in the park.
It could be said that living was worse than dying.
Old Master Su had considered suicide more than once, to end his life.
But because of Su Yuyan, he had abandoned such thoughts.
If his granddaughter was not living well, how could he, as her grandfather, dare to report to the King of Hell?
"Grandpa!" Su Yuyan cried again.
But this time, she cried from overwhelming emotion.
Finally!
She finally saw hope.
Su Qichuan and Su Xingyang also wore smiles on their faces.
The old man being able to stand up again was indeed good news for them.
As long as Old Master Su resumed control of the Su family, Su Qishan would no longer be able to oppress them.
Of course, even without this future benefit, Su Qichuan wished for his old father's full recovery, as the man before him was his biological father.
"Good, good, good! From now on, our family must be harmonious and healthy!"
Seeing the care from his second son and grandchildren, Old Master Su was also very happy.
This moment, he had waited for a long time.
And all hope was now placed on a young man named Zhou Yu.
Perhaps, it was all a matter of chance.
If it weren't for that engagement, and if it weren't for his connection with Zhou Yu's master, he would not have this glimmer of dawn today.
On the other hand, Su Qishan.
Looking at Old Master Su on the bed, his daughter, and Su Qichuan's father and son, a feeling of jealousy spread deep within him.
It was clear that that side did not belong to him.
And it was very likely that there would no longer be a place for him.
But Su Qishan had no regrets.
At this moment, Zhou Yu walked towards him.
"Alright, Uncle Su, now, shouldn't we settle our accounts properly?"
"Settle accounts? What accounts?" Su Qishan asked, confused.
What accounts did he have to settle with Zhou Yu?
Weren't they discussing who poisoned Old Master Su?
How did they get sidetracked?
"Uncle Su truly has a forgetful nature."
Zhou Yu smiled faintly, spread his hands, and pointed to Zhang Rufeng in the corner, "Recently, you and she have not been sparing in revealing my and Yuyan's whereabouts to the Zhang family, have you?"
"So what? Yuyan is my daughter. You took my daughter away before. As her father, shouldn't I find a way to get her back?" Su Qishan retorted.
"Oh? Is it just about getting Yuyan back?" Zhou Yu asked again.
"Then tell me, what else do I want?"
Su Qishan harbored a fire within him.
But there was nowhere to vent it.
He had to hold on!
He had to hold on until the arrangements in the dark were finalized, and the last trouble was dealt with.
Zhou Yu smiled, "Zhang Shaohua of the Zhang family is young and wealthy, a young master from a top family in Yunhai City, and he recently became a new member of the Dragon Group. His future is limitless. As for me, with no identity or background, I am indeed not suitable to be your son-in-law."
"Do you understand these things and still don't know your place?"
"But even so, Uncle Su shouldn't have repeatedly betrayed me and your daughter. Don't tell me your daughter is so insignificant in your eyes, a sacrifice to strengthen the family? Will you gain glory if the Su family becomes powerful because of this? Moreover, how will the Zhang family view you in the future? How will they view all the disciples of the Su family?"
"These are not your concern."
"I naturally don't want them to be my concern. But now, after all, I am still Uncle Su's son-in-law. As a son-in-law, I naturally have to do what I should do."
Hearing Zhou Yu repeatedly mention that he was the Su family's son-in-law, Su Qishan wished he could strangle the young man before him.
If it weren't for Zhou Yu, his plan would have succeeded long ago!
And the Su family would have already hitched their wagon to the Zhang family!
What if he was a divine doctor?
What if he had a close relationship with Yunhai's richest man?
Could that compare to the current Zhang family?
Why should Zhou Yu be compared to the young master of the Zhang family?
"Zhou Yu! Now is not the time to talk about these things. Either you produce evidence, or hurry up and treat the old man," Su Qishan said.
At this moment, he could no longer drive Zhou Yu away.
He had to wait until this young man cured the old man first.
Were it not for Su Qichuan being present, Su Qishan would have directly kicked him out.
He didn't want Old Master Su to stand up again, but now he had no choice.
More importantly, Su Qishan was not clear about how many people the old man and Su Qichuan had secretly deployed within the bodyguard team at the old residence.
Before he obtained specific intelligence, he couldn't afford to fall out with them.
Zhou Yu scoffed, "The evidence is escaping, and your men are trying to pursue and kill him. Is that right or not?"
"I don't know what you're talking about!"
Su Qishan would naturally not admit it.
Among the bodyguards he had sent out before, one was tasked with secretly eliminating Liu Fu if he tried to escape!
However, even if Zhou Yu discovered it now, what of it?
With so much time having passed, the assassin should have succeeded.
