Seeing that he had finally calmed down a bit, Jiang Youchen quickly steered the conversation back on track. "Dr. Gu, it's not about how to treat it, it's about how to prevent it. The problem is, this vaccine requires four shots, two for the first time, and three in total. But we don't want Young Master Wen to know. Do you have any good ideas?"

Doctor Gu strained his eyes wide, "What kind of injection? What kind of disease or vaccine?"

He was listening very attentively, but he still couldn't understand what was going on.

Just like when I saw the instruction manual for that "Xinbibao" product last time, I felt a terrible sense of being an outsider.

Xiao Youran first briefly explained what a vaccine is, and then took out the syringe and vaccine vial, briefly explaining the injection method.

Doctor Gu's eyes widened, and he suddenly took the small vial of injection fluid with a mixture of caution and excitement, exclaiming in shock, "This...this is a glass bottle? What happens after it's used up?"

Xiao Youran casually replied, "I threw it away."

Medical waste has no choice but to be thrown away.

"What? What a waste! What a terrible waste!" Doctor Gu cried out in anguish, glaring angrily.

Xiao Youran was speechless again. Why are you going off-topic again?

Doctor Gu suddenly slapped his forehead. "I know! You used this injection method to cure the child's snake venom, didn't you? Only in this way can the antidote quickly enter the bloodstream and neutralize the snake venom!"

Little Youran gave Doctor Gu a thumbs up, "Grandpa Doctor, you're absolutely right!"

Doctor Gu stared at the brother and sister for a long time, then raised the glass bottle in his hand, "Where did these strange things come from?"

Jiang Youchen glanced at his sister and quickly answered, "This was left to me by an old doctor before he died when I was in Dingzhou."

Xiao You Ran: ……

Won't this give away the secret too quickly? Didn't they say it was a family heirloom?

Doctor Gu blinked and asked very seriously, "Little Fu Bao, Grandpa will ask you one last time, do you really not want to become Grandpa's apprentice?"

Xiao Youran blinked, looking very hesitant.

Doctor Gu suddenly beamed with joy, "You don't want to get better? Then... this old man will become your apprentice!"

Xiao Youran: !!!

Jiang Youchen: !!!

Seeing that the white-haired, white-bearded Doctor Gu was about to kneel before the little child, Jiang Youchen acted decisively. She rushed in front of Doctor Gu, grabbed his knees, and successfully stopped him from kneeling. Instead, she knelt down first, crying out, "Master—Father—"

In that instant, Xiao You Ran actually recognized the Monkey King's heartfelt cry—"Master—"—that had echoed through the ages after he had been imprisoned under the Five Fingers Mountain for five hundred years.

Then Jiang Youchen let out another shrill cry, "Disciple—pays respects to Master—"

Xiao Youran was utterly speechless: ...

Doctor Gu was stunned, first looking completely bewildered, then suddenly slapped Jiang Youchen on the forehead, "Who told you to beat me to it?!"

Jiang Youchen: ...

He didn't think that much about it; he just couldn't bear to look at that scene.

An old man over fifty years old kneeling down before his own little sister—how could that be allowed? Wouldn't that shorten the little sister's lifespan?

The only way to stop this bizarre and eccentric Doctor Gu is to unleash this ultimate move!

The moment Doctor Gu slapped him, his mind suddenly cleared.

Hmm? It seems like I can't refuse either?

Was it he who initially suggested taking him as his apprentice?

His initial intention in wanting Xiao Youran to become his apprentice was to use his status as her master to overpower them, so that they would present him with those strange and unusual medicines and instruments, which might open the door to a new world of medical skills and allow him to make a breakthrough in his medical expertise.

But if they really are unwilling, then it's not impossible for someone like me, who has been obsessed with medicine for many years, to bow down for a pittance—oops!—to learn new medical techniques!

Moreover, the things Xiao Youran just took out and the vaccine that could prevent rabies were far superior to his medical skills!

In the path of medicine, the strong are your teachers!

So for a moment, he had the idea of ​​becoming this little baby's apprentice.

But if Jiang Youchen is willing to become my apprentice... then I won't have to call this little baby 'master'. I can also use the principle of respecting the master to ask them to bring out more divine medicines for me to study... Wouldn't that be the best of both worlds?

Hehehehe!

He laughed.

Thinking this, he helped Jiang Youchen up, pinched and rubbed her left and right, nodded and stroked his beard, saying, "Hmm, you really do have extraordinary talent, suitable to be the successor of my Gu family!"

Jiang Youchen: ...

Why do you insist on having extraordinary physical characteristics when taking on a medicine apprentice? It's not like you're passing on unparalleled martial arts skills.

Furthermore, when you mentioned someone with extraordinary bone structure, were you referring to his sister?

Xiao Youran, her face full of exasperation, reminded them of today's main topic, "Gentlemen, regarding the vaccination of Young Master Wen... is there a procedure?"

Doctor Gu's eyes lit up, and he patted his chest, saying, "Leave it to me!"

"That's great!" Xiao Youran shoved the syringe into his hand.

Doctor Gu was overjoyed, picked up the syringe and examined it closely, then looked bewildered, "How do I use it?"

Xiao Youran stumbled and almost fell to the ground.

She looked up at Doctor Gu, both amused and exasperated, and said in a childish voice, "How about you become my apprentice, Grandpa Gu?"

She called out to Grandpa Gu in a sweet, soft voice, while telling him to become her apprentice. The whole thing was incredibly bizarre.

Doctor Gu flicked his sleeves and said, "That won't do! Your brother has already become my disciple, so by a rough calculation, you're practically my apprentice too!"

Xiao You Ran: ……

You actually know about rounding?

...

On the other side, Nan Zhuo cleaned up the young master, dried him off, and helped him onto the bed, muttering, "That old Gu is getting more and more unreliable. Doesn't he know you're injured, Master? Why is he taking so long to come back?"

Wen Yuanbai's lips twitched. "Have you forgotten how he initially acknowledged me as his master? It's normal for him to be resentful; you've been nagging about it for three years now."

Nan Zhu blinked, then laughed and said, "Who told him to try and outdo you in misfortune? Who can compare to you?"

Wen Yuanbai:......

That's heartbreaking!

He gave Nan Zhu a cold glance. "Who told you to bring this up?"

Nan Zhuo carefully helped him lie face down on the bed, then draped the blanket over him, and said with a smile, "Master, I'll go out and find him to bring back for you to apply the medicine."

Although he had some medicine for external injuries, he didn't dare to use it indiscriminately because his master was weak and he didn't know if the medicine would clash with his own.

After saying that, he went out and closed the door behind him.

Wen Yuanbai lay on the bed, closing his eyes and thinking about the scenes on the mountain today. He still couldn't understand why, when he saw the lynx rushing straight at the little girl's face, he stepped forward and protected her in his arms without thinking.

He just felt that if the lynx scratched her face, she would definitely cry miserably, and might even be disfigured... He felt a little... heartbroken.
