"Twenty percent, after all, it's an opportunity. If you don't get treatment, grandpa will die."

Gu Mingyao's eyes flickered, and a breath sealed Gu Wanqing.

"Brother, you!" Gu Wanqing's expression changed drastically.

"Sister, I'm sorry. Grandpa, I have to save him. As for Qin Cheng's kindness to my Gu family, I will find a way to make up for it in the future, but I have to have the pure sun crystal."

"Qin Cheng, take action."

Gu Mingyao shouted loudly.

"Bastard thing!"

Before Qin Cheng could react, a light cough could be heard in the distance.

An old man walked slowly on crutches.

"Grandpa." Gu Mingyao's expression changed drastically when he saw the old man.

The old man actually came in person regardless of his health.

A slap fell on Gu Mingyao's face, but Gu Mingyao showed no anger at all and endured it silently.

"Is this how I teach you how to behave?"

The old man's complexion was sallow and his body was stooped. There was a lifeless air outside his body. He coughed as he spoke.

"Grandpa, it's your grandson's fault, please don't be angry." Gu Mingyao went over and supported the old man.

"Everyone is destined to die, so why do you have to go against heaven for me? How can the Niyuan Pill be so easy to refine?" The old man said with emotion: "I can train you brothers and sisters, and I will die without regrets."

."

"grandfather."

Brother and sister Gu Mingyao burst into tears immediately.

Qin Cheng suddenly felt a slight pain in his heart. He thought of Su Wan and Mr. Su, and then thought of the unfilial Lin family and Mr. Lin.

He walked over slowly.

"Qin Cheng. I'm sorry about this. It's over now. You can go." Gu Mingyao stood up and said.

"Mr. Qin, Mingyao doesn't know your identity. I have offended you many times before. I apologize to you on his behalf." The old man also said.

"What you just talked about was Ni Yuan Dan?"

Qin Cheng's words made the Gu family's expressions change slightly.

"This is our family's business and has nothing to do with outsiders."

Gu Mingyao frowned slightly, his favorable impression of Qin Cheng weakening a lot.

He doesn't like people who like to hear about other people's disasters and gossip.

"You misunderstood." Seeing the dissatisfaction in Gu Mingyao's eyes, Qin Cheng shook his head.

"If you can find a quiet place, let me elaborate."

This is not the place to talk, and Qin Cheng is not willing to say too much.

"good."

Gu Mingyao frowned, not knowing what Qin Cheng was going to say.

They got into their respective cars and left here.

"After today, there will definitely be big changes in the Heroic List."

Watching a few people leave, someone secretly laughed.

"I wonder how far Qin Cheng and Gu Mingyao will advance." Someone was excited.

"In short, this battle is a good start for the upcoming battle in the secret realm."

"At this time, geniuses from all walks of life have gathered together. There must be a lot of fighting. It will be exciting to watch."

These people whispered, all looking forward to it.

Gu Wanqing invited Qin Cheng to a courtyard on the outskirts of Kyoto.

A few people sat down and Qin Cheng said something surprising.

"If it is Ni Yuan Dan, there is no need for pure Yang Jing Stone."

"What?"

The faces of the Gu brothers and sisters all changed slightly.

"You also know medical skills?" Gu Mingyao was surprised.

"Brother, Brother Qin Cheng may really understand this." Gu Wanqing thought that she was poisoned at that time. Qin Cheng took out the pill to help her detoxify.

"But Niyuan Pill is not an ordinary pill. It is a high-grade elixir."

Gu Mingyao was still doubtful.

Qin Cheng is too young to let him believe it.

Qin Cheng didn't explain anything. He took out a pen and paper and scrawled a line of text on it.

"This is the prescription for Ni Yuan Dan. You can see what I wrote."

Gu Mingyao took the letter and doubted it, looked at it for a few times, and handed it to Gu Wanqing. His expression became extremely complicated.

"Most of them are exactly the same, but the key drugs are completely different."

"I don't know who Doctor Hu is, but there's obviously something wrong with his prescription," Qin Cheng said.

This Ni Yuan Dan comes from the recipe left by my father, so there is nothing wrong with it.

Qin Cheng was naturally extremely convinced.

"Then Divine Doctor Hu used to be a guest of the Jiang family. Is it really wrong?" Looking at Qin Cheng's determined attitude, the old man was also a little confused.

"Are you your guest from the Jiang family?" Qin Cheng smiled.

"Young friends may not know that among the three sects and eight families in the hidden world, the Jiang family represents the top level of medicine refining. Their guests are all called the God of Medicine," the old man explained.

"It turns out that if you become a guest of the Jiang family, can you be called the God of Medicine?"

Qin Cheng took out a token and handed it to the old man.

Seeing the token, the old man was instantly dumbfounded.

"You, you are the chief guest of the Jiang family!"

The Gu family siblings were even more stunned.

They were able to ask Jiang Jiaqing for diagnosis and treatment, and they already felt that he was the best doctor.

But he didn't expect that the Qin Cheng in front of him had a higher status.

The chief guest is equivalent to being superior to all guests.

If Dr. Hu is the god of medicine, then wouldn’t Qin Cheng be the sage of medicine?

Qin Cheng has advanced cultivation and is actually a top alchemist.

Otherwise, he would never be able to become someone recognized by the Jiang family.

"I heard that Mr. Jiang's guest once refined a sixth-grade top elixir, but Mr. Qin?"

The old man thought of something and his eyes shone brightly.

Qin Cheng smiled and did not answer.

But this has proven everything.

The breathing of the Gu family members became much faster.

"Master Qin, please save grandpa." Gu Wanqing knelt down with a plop, a look of pleading on her face.

Gu Mingyao hesitated for a few seconds and was ready to kneel down.

However, Qin Cheng noticed it early and stopped both of them.

"Don't be too excited, I want to see the old man's condition first." Qin Cheng did not ask for help. There are too many difficult and complicated diseases in the world, and he cannot ensure that the medicine will cure them.

The old man also gave a wry smile.

Originally he thought he had no chance of survival, but now he felt a glimmer of hope.

Qin Cheng gave Mr. Gu a good diagnosis and treatment.

"How?" Gu Wanqing asked with hope.

"Then the prescription given by Doctor Hu is correct. Mr. Gu must have refined Shou Yuan before?" Qin Cheng said.

"That's right." Mr. Gu's words surprised the Gu family siblings.

This is something neither of them know.

"Back then, the Lingnan Sword Sect faced an invasion from a powerful enemy. As the elder of the Sword Sect, I sacrificed Shouyuan's secret sword skills to kill the opponent."
