It took Qin Han Chu a full three hours before he finally relaxed.
The three brothers had not disappointed Qin Han Chu; they had endured pain that ordinary people would find unbearable.
And Qin Han Chu had not disappointed them either. The three brothers had now reached the realm of Grandmasters.
A Grandmaster was one who could transform the vital energy within their body into true essence.
With true essence condensed, a martial artist could generate internal force.
Aided by internal force, a martial artist's combat power could advance by leaps and bounds.
To help the three brothers break through, Qin Han Chu had exhausted his own true essence.
Another two hours passed, and Qin Han Chu finally recovered to his peak condition.
"I really didn't expect that by helping them break through, my own strength would also improve."
Opening his eyes, Qin Han Chu smiled happily.
Since achieving the realm of Great Grandmaster, Qin Han Chu's progress had been very slow.
However, the process of helping the three brothers had made him more adept at controlling his true essence.
It was precisely because of this that Qin Han Chu's strength had improved again.
"Thank you for your cultivation, Master!" At this moment, the three brothers stood up in unison and respectfully addressed Qin Han Chu.
Qin Han Chu stood up and said, "The Blade Master will surely send people to investigate. You must not go out for now."
"Understood." The three brothers nodded.
At the same time, an old man led eight men in black to the Jin family's old residence.
In the old residence, Old Madam Jin was watering the flowers.
Since Jin Hailu took sole control, Old Madam Jin had been living a leisurely life of idleness.
"Madam, there are some people outside who want to see you," a Jin Lion guard said urgently as he entered.
"Who are they?" Old Madam Jin asked.
"They say they are from the main lineage of the Jin family."
Upon hearing this, Old Madam Jin's expression changed drastically, and she said excitedly, "Please invite them in quickly!"
Ever since Jin Hailu took away the power of the Jin Lion Group, Old Madam Jin had been waiting for this day.
Now that the main lineage had sent people, she could finally reclaim everything that belonged to her.
A moment later, the old man, leading his subordinates, arrived at the main hall of the Jin family's old residence.
In the hall, the old man saw Old Madam Jin leaning on a cane.
"Are you the person in charge of the Jin Lion Group?" the old man asked haughtily, looking at Old Madam Jin.
Old Madam Jin shook her head and said, "The Jin Lion Group has already been handed over to my granddaughter, Jin Hailu."
"I am asking about the true person in charge," the old man said sternly.
"Everything in the Jin Lion Group has been transferred to Jin Hailu. I am just an ordinary old woman now," Old Madam Jin replied.
"If that is the case, then have Jin Hailu come to see me," the old man said indifferently.
Old Madam Jin glanced at the guards behind the old man and then said, "Shouldn't you prove your identities first?"
The old man took out a golden plaque and casually placed it in front of Old Madam Jin.
This golden plaque seemed to be only half of it, incomplete.
Seeing the golden plaque, Old Madam Jin's eyes glinted with excitement.
She took out another plaque and placed it together with the old man's plaque.
The two plaques, when placed together, formed a complete golden medal.
Both the pattern and the seam where they joined fit perfectly.
"Please take a seat, everyone. I will inform Jin Hailu right away." Old Madam Jin respectfully hosted the old man.
The old man sat on a chair and nodded proudly.
A moment later, Old Madam Jin hung up the phone and said to the old man, "I have notified her. She will be here soon."
"Does she know about the Jin family's main lineage?" the old man asked.
Old Madam Jin quickly shook her head, "I have not informed her about this matter."
Hearing this, the old man angrily said, "Have you forgotten the rules? You didn't inform her about the main lineage's existence before transferring power?"
Seeing the old man's anger, Old Madam Jin hurriedly explained, "You may not know, but I did not willingly transfer this power."
"What? A mere woman could force you?" the old man asked.
Old Madam Jin quickly recounted the events, including the incident at the Han family's estate.
"This young man is not only powerful but also has the backing of Divine Physician Hu's connections. I am truly powerless to resist."
"I have been waiting for someone from the main lineage to preside, and today I have finally waited for them."
Old Madam Jin said excitedly.
"In his early twenties, Ninth Grade late stage!" the old man asked in shock, "Are you sure?"
"How dare I deceive you?" Old Madam Jin replied.
The old man fell into thought and then said, "Find this person as well."
Old Madam Jin nodded quickly and called Jin Hailu again.
An hour later, Jin Hailu's car stopped outside the old residence.
As the car door opened, Qin Han Chu and Jin Hailu stepped out together.
"Chairwoman," a Jin Lion guard stepped forward to greet them.
"What did Grandma want me for?" Jin Hailu asked.
"Some people came today, saying they are from the main lineage," the guard replied.
The main lineage?
Jin Hailu was even more confused. What was going on?
A moment later, Qin Han Chu and Jin Hailu entered the main hall of the old residence.
"Hailu, this is a senior from the Jin family's main lineage. Hurry and pay your respects," Old Madam Jin introduced Jin Hailu to the old man.
"Greetings, senior." Although Jin Hailu did not know the details, she still paid her respects to the old man.
"Yes, you are dismissed." As he spoke, the old man's gaze fell on Qin Han Chu.
He truly did not expect that someone so young could reach the Ninth Grade realm.
"Grandma, what did you want me for?" Jin Hailu asked.
"I didn't tell you before, but our Jin Lion Group is a branch of the Jin family of Jinling."
"Every three years, each branch must submit twenty percent of its profits to the main lineage."
"This is the senior responsible for collecting the tribute," Old Madam Jin said.
"I've never heard Grandpa mention this," Jin Hailu said.
"This matter is a top secret. The new person in charge is only informed when power is transferred."
"Why didn't you tell me before?" Jin Hailu asked.
Old Madam Jin's expression turned somewhat unpleasant. "Your power was seized by Qin Han Chu. Do you think I would willingly disclose everything?"
"What you say is not wrong," Qin Han Chu said with a smile.
Jin Hailu glanced at Qin Han Chu and then asked, "Since we have to submit tribute, what can the main lineage give us?"
"The startup capital for the Jin Lion Group originally came from the main lineage, so it is natural to repay the main lineage."
"Furthermore, if a branch encounters a life-or-death crisis, the main lineage will provide assistance," the old man said in a deep voice.
In reality, Jin Hailu did not believe Old Madam Jin's words.
She felt that this was a play staged by Old Madam Jin.
"Give me time to investigate," Jin Hailu said after a moment of thought.
"You don't believe me?"
Although Old Madam Jin was old, she was not confused.
Jin Hailu's request to investigate clearly showed that she did not believe her words.
"You are indeed not trustworthy."
Qin Han Chu had a very bad impression of Old Madam Jin and also believed that Old Madam Jin was likely lying to extort money.
"This is a family matter for the Jin family. It's best not to get involved."
"The strength of the Jin family's main lineage is terrifying. Even if you are a Ninth Grade martial artist, you are not qualified to oppose them."
With members of the Jin family's main lineage present, Old Madam Jin gained confidence.
If it were before, she would not have dared to speak to Qin Han Chu like this.
