In the evening, Jian Yiling took her ointment and went to Yu's house next door.

Zhai Yunsheng became the first clinical human tester of Jian Yiling's scar removal ointment.

Prior to this, all of Jian Yiling's experimental data were still animal.

Because according to the regulations, enough animal experimental data must be obtained before it can be applied to humans.

And Jian Yiling dared to take Zhai Yunsheng for the first human experiment because her formula had been widely used before she crossed over, and the actual human experiment data had already been enough.

Jian Yiling asked Yu Xi to help Zhai Yunsheng apply ointment.

Zhai Yunsheng's wound is still relatively new, and it is a good time to use the ointment.

At the request of Jian Yiling, Yu Xi once again contributed one of his "firsts" - the first time to give people medicine.

Zhai Yunsheng showed one arm, and a pair of eyes seemed to be understanding Jian Yiling:

"You made this ointment yourself?"

"Hmm." Jian Yiling replied truthfully.

Hearing this, Yu Xi's hand, who was applying the ointment, trembled.

Ling Shen made it himself? That wouldn't go wrong, would it?

This Shengye's arm is golden! What kind of problem does this have......

Yu Xi didn't dare to think about it.

Just thinking of the terrifying eyes of Old Man Zhai and Second Master Zhai, Yu Xi felt that his legs were weak.

Yu Xi couldn't help but start praying in his heart: Amitabha, God bless, Sheng Ye will not have any problems with this ointment! I don't want to be able to really eliminate the scar, but I ask Sheng Ye to be safe!

"Are you short of investors for this ointment?" Zhai Yunsheng asked.

"Not yet."

It is still in clinical trials.

It can be used by the people around you, and it is about to be mass-produced, so more clinical trial data must be needed to support it.

Then Jian Yiling applied for a patent and license again before large-scale production.

So the matter of investment is still very late, and Jian Yiling has not considered it yet.

"How about you invest?"

"Not good." Jian Yiling refused.

"Huh?"

"There are other relationships, not suitable for business."

Jian Yiling felt that doing business could not involve feelings.

Because it is said that talking about money hurts feelings.

Jian Yiling didn't know how to deal with emotional problems, but she knew how to deal with money-making things.

So she doesn't want to be emotionally involved when she makes money, which complicates her simple problems.

"Other relationships? What relationship? Zhai Yunsheng asked.

Jian Yiling hesitated, not knowing how to describe their relationship.

It doesn't seem good to say that they are friends.

Jian Yiling remembered that Zhai Yunsheng rarely admitted that others were his friends.

For those who do not claim to be his friends, Zhai Yunsheng will tear down the stage mercilessly.

"You're Yu Xi's friend." Jian Yiling found a relatively reasonable answer.

This answer made Zhai Yunsheng's face gloomy all of a sudden.

Even Yu Xi, who was giving Zhai Yunsheng medicine, was stunned.

"So, for a long time, you treated your father's wounds and removed his scars, for Yu Xi's sake?"

The expression on Zhai Yunsheng's face was smiling, but this smile was extremely mad.

Yu Xi saw that his legs were weak.

He hurriedly looked at Jian Yiling.

But seeing Jian Yiling's calm face and clear eyes, he didn't seem to be aware of the danger.

"Ling Shen, you, you ......"

Yu Xi tried to save it, but didn't know what to say.

When the book is used, it is hated less, and when the word is spoken, it is hated to be poor.
