Su Qing came back in about twenty minutes.

Xiao Chen looked at Su Qing and smiled bitterly. He told him to drive slowly, it would not work at all.

On weekdays, it takes at least half an hour, but she rushed back in twenty minutes, which shows her mood.

But thinking about it again, her biggest obsession in her heart now should be her parents.

Guan Duanshan is here, and when it comes to her parents, how can she be calm?

"Old Guan."

Su Qing first greeted Guan Duanshan, then looked at Xiao Chen.

"What's going on?"

"Lao Guan, please tell me."

Xiao Chen looked at Guan Duanshan and said.

"good."

Guan Duanshan nodded, took out a folder from the black bag next to him, and handed it to Su Qing.

"You have a look first."

"good."

Su Qing took it and looked it up.

"What's this?"

Xiao Chen was curious.

"About those scientific research topics."

Guan Duanshan drank tea and said casually.

"Hmm? Then why didn't you show me just now?"

Xiao Chen frowned.

"Show it to you, do you understand?"

Guan Duanshan curled his lips.

"If you can't understand, wouldn't it be useless?"

“…”

Xiao Chen was speechless, but... it seemed that was the case.

“Where did I get this?”

Before he could finish watching, Su Qing was not calm, and suddenly raised her head and looked at Guan Duanshan.

"Those are all handed over to me by someone secretly."

Guan Duanshan was very satisfied with Su Qing's reaction and said slowly.

"Someone gave it to you secretly?"

When Su Qing heard Guan Duanshan's words, she widened her eyes. This was recorded in her notebook.

Then, she thought of something and opened her eyes wide.

"Is it my parents? Have you met my parents?"

"No, I don't know who it is, but... I guess it's them."

Guan Duanshan looked at Su Qing and said.

"If you hadn't contributed part of the notebook back then, I wouldn't have connected it."

"Can you confirm?"

Xiao Chen also looked at Su Qing and asked.

“It can be confirmed.”

Su Qing nodded.

"These two are recorded in notebooks, one of them... I have also verified it, and you have seen it."

"It won't be...that blue potion?"

What did Xiao Chen think of?

"Yes, it's just blue potion."

Su Qing nodded.

“Exactly the same.”

"You already have the finished product?"

Guan Duanshan was also surprised.

"Give it, that's it."

Xiao Chen took out the blue potion from the bone ring and handed it to Guan Duanshan.

Last time he planned to show off to Guan Duanshan, but this old guy was unauthentic and put his latest generation of powerful potion in his pocket.

Seeing this, he didn't take it out any more. He took it out and was also put in his pocket.

"The above said, it has a good effect on external trauma?"

Guan Duanshan took it and subconsciously put it in his pocket. But he thought of something, smiled awkwardly and asked.

"Lao Guan, you are a giant after all, don't do this, okay?"

Xiao Chen said contempt, then took out a dagger, gently cut his finger open, and blood flowed out.

"Oh, Lao Guan, give me the blue potion."

"You're gone? I'll take this back."

Guan Duanshan said holding the blue potion.

“…”

Xiao Chen was speechless and could only take out another bottle from the bone ring and pour it on the wound.

Soon, the blood stopped and the scab was visible to the naked eye.

"this……"

Guan Duanshan's eyes widened and his face was shocked.

"Is the effect OK?"

Xiao Chen smiled.

"Isn't it much better than the medicines that are available now?"

“How did it be done?”

Guan Duanshan looked at Xiao Chen's hand and asked.

"I didn't see clearly, you can demonstrate it again..."

"What? I will demonstrate it to you again? Isn't it wrong?"

Xiao Chen was even more speechless. What was this old guy thinking?

"Yes, I didn't see it clearly just now, it's amazing."

Guan Duanshan nodded.

"Come on, the knife will give you, you will cut yourself, look slowly, feel slowly... you will find it even more magical."

Xiao Chen said, handing the dagger to Guan Duanshan.

"If it doesn't work once, just do it a few more times. Don't worry about not having enough medicine. I have a lot of it, and the amount is enough!"

"Well, forget it, this has to be left to professionals, what can I feel."

Guan Duanshan coughed dryly and looked at Su Qing.

“What is the principle?”

"This... involves a lot of professional knowledge, and I'm afraid I can't explain it clearly."

Su Qing looked at Guan Duanshan and said.

"You hand this over to the laboratory, and those researchers can figure it out, but this is the first generation, and I am the third generation."

"You are the third generation? It's amazing."

Guan Duanshan praised him.

"You look at something else, and then we'll talk about it."

"good."

Su Qing nodded, suppressed many questions, and continued to read.

"Boy, give me a few more bottles."
