Time Travel: I'm a Flower Thief

Xie Xiaoyi smiled at his senior sister: "We're still a long way off; the most crucial part is yet to come!"

Upon hearing this, Hua Suwen asked in confusion, "Isn't this the final antidote?"

Xie Xiaoyi hummed in agreement: "This isn't even a semi-finished product; synthesizing this medicine is extremely difficult."

"Junior brother, what's the name of this antidote?"

"Penicillin! Senior sister, please bring me that ceramic jar!"

"OK."

Hua Suwen handed over the pottery jar and then said nothing more, simply watching him quietly.

Xie Xiaoyi knew that refining penicillin in this ancient environment was far more difficult than others imagined, with four major obstacles in front of him, and it was by no means as easy as it is in modern times.

Firstly, it is extremely difficult to extract penicillin-containing liquid from the culture without the help of sophisticated equipment.

Secondly, one must go to great lengths to remove impurities from the medicinal liquid; the slightest mistake could ruin the entire effort.

Thirdly, it is necessary to completely eliminate surrounding contaminants. In ancient times, there were no sterile conditions, making this step extremely difficult.

Fourthly, and most importantly, there is no syringe in the world, so even if the medicine is prepared, it cannot be delivered directly to the lesion to exert its effect.

He has already solved the first difficulty level.

Using the internal energy of the Azure Dragon Absorbing Water, small water droplets of Penicillium stock solution have condensed from the jar where Penicillium was being cultivated.

The next challenge is to solve the second problem: remove impurities and obtain a clean penicillin solution.

He steadied himself, flicked his wrist, and slowly poured the ball of water containing penicillin solution from his palm into the empty ceramic jar that Hua Suwen had handed him.

Immediately afterwards, he gently placed his right palm on the outer wall of the pottery jar and slowly activated a wisp of warm yet chilling true energy.

The chill seeped into the jar through the earthenware wall, transforming into wisps of invisible cold wind that rapidly swirled around the medicinal liquid.

In a short while, the penicillin solution was blown away by the cold wind and turned into wisps of cool mist that rose gently from the mouth of the can.

Xie Xiaoyi's eyes narrowed, and his left hand suddenly formed a hook, unleashing the internal force of the Azure Dragon Absorbing Water!

A suction force surged from his palm, drawing back all the wisps of blue mist in the air and condensing them once again into a clearer, more lustrous, and more medicinally pure water sphere in his hand.

He was overjoyed. The second step of purification, removing impurities and retaining the essence, had already begun to produce the medicinal effect.

The next step is the third step: eliminating unwanted bacteria!

Xie Xiaoyi knew that if the bacteria in the water sphere were used directly as medicine, it would not only fail to cure the disease, but would also cause new illnesses.

His already mastered Frost Qi was now coming in handy.

He slightly bent his fingertips and slowly injected a wisp of cold air into the water sphere. Although the temperature did not drop to freezing point, it was enough to inactivate and kill most harmful bacteria.

Penicillium is inherently cold-resistant, and in this slightly chilly air, it not only remains undamaged but also remains stable and enters dormancy.

Those bacteria that couldn't withstand low temperatures were completely wiped out by this precisely controlled icy energy.

Xie Xiaoyi dared not be careless, and continued to subtly control the hard-won penicillin solution with his true energy.

This was far more mentally taxing than practicing swordsmanship in the East Sea, and a layer of cold sweat gradually seeped from his forehead.

Hua Suwen stood aside, unable to understand the mystery of the clear water in his palm, let alone the principles of penicillin and sterilization.

But she could see it—every moment her junior brother concentrated, every slight tremor, he was giving it his all.

Her heart softened, and she took a half-step forward, gently lifting her sleeve to carefully wipe the cold sweat from his forehead, her voice soft:

"Junior brother, you've worked hard."

Concentrating on his work, Xie Xiaoyi didn't dare to speak, but simply gave her a faint smile.

In less than the time it takes to burn half an incense stick, the three steps were completed.

Xie Xiaoyi held the medicinal bead in his palm, looked up at Hua Suwen, and said in a steady voice:

"Senior sister, please lead the way and open the door. We're going to find Mu Pingting."

Without the slightest hesitation, Hua Suwen obediently replied, "Okay."

She knew her junior brother must be having a hard time, so she quickly stepped forward, gently pushed open the door to the quiet room, and quietly led the way for him.

The two walked one after the other and soon arrived at the medical room where Mu Pingting was recuperating.

Inside, Hua Lingshu was tending to the bedside when the two entered. Just as he was about to speak, his gaze was drawn to the ball of medicinal liquid in Xie Xiaoyi's palm, which was glowing faintly.

"Junior brother, what is this?"

Xie Xiaoyi smiled faintly: "This is the antidote for Sister Mu's illness."

As the eldest disciple of the medical school, Hua Lingshu had seen many difficult and complicated diseases throughout his life, and he was especially aware of the harm caused by venereal diseases.

This disease is caused by pathogenic toxins that penetrate the bones, seep into the blood and marrow, and there has never been a cure since ancient times. At most, medication can only slightly suppress the symptoms. Even if one exhausts all their medical skills, it is difficult to eradicate the root cause of the disease.

He gazed at Mu Pingting, who lay on the bed looking sickly and haggard, then at the faintly glowing medicinal bead in Xie Xiaoyi's palm, and asked in a deep voice:

"Junior brother, are you aware that venereal disease is incurable? Ordinary medicines struggle to even suppress it; are you confident in your ability to treat it?"

Xie Xiaoyi nodded: "Although Sister Mu unfortunately contracted the drug, it hasn't reached the most serious stage. I'm 70% sure."

Seeing his confident expression, which didn't seem like empty talk, Hua Lingshu, though still puzzled, finally nodded:

"Very well, there are no fixed rules in medicine, and no constant prescriptions in medicine. Let's try your method. I wonder if this medicine is for internal use or external application?"

"Neither taken internally nor applied externally."

Hua Lingshu was taken aback again: "Then... how should we administer the medicine?"

Mu Pingting, lying on the couch, frowned slightly, her eyes full of confusion: "Xie Mo, neither internal nor external application, could it be... that I can be cured just by smelling it?"

Xie Xiaoyi gently shook her head upon hearing this: "Sister Mu, just trust me. It's not for smelling. First, stretch out your arm and roll up your entire sleeve!"

Although Mu Pingting was puzzled, she trusted him completely. She slowly raised her hand and gently lifted one sleeve to reveal a section of her smooth forearm.

Xie Xiaoyi walked to the bedside, his gaze falling on her pale and haggard face, his heart sinking slightly: "Senior Brother, please fetch the silver needles."

Although Hua Lingshu did not understand why, he still followed her instructions and brought silver needles and candles to quickly disinfect them.

Xie Xiaoyi pointed to the inner side of Mu Pingting's forearm, at the elbow crease where the veins were most prominent, and said in a deep voice:

"Punch the needle here—the blood vessels here are the shallowest and straightest, allowing the medicine to enter the body the fastest."

"You use silver needles to pierce her skin and penetrate her meridians, and I will deliver this medicine into her body."

Hua Lingshu was startled. In his many years of medical practice, he had never heard of such a method of directly injecting medicine into the bloodstream. However, seeing Xie Xiaoyi's resolute gaze, he nodded.

"Okay, I'll give you the acupuncture."

Without saying another word, he took the silver needle, briefly sterilized it over a candle flame, and then pierced Mu Pingting's elbow vein.

The needle pierced Mu Pingting's skin, and a drop of bright red blood immediately seeped from her vein.

"Hiss—" With a slight pain, Mu Pingting couldn't help but frown slightly.

Xie Xiaoyi slowly walked to her and sat down, his fingertips gently twirling, his mind slightly stirred.

The ball of penicillin water rapidly contracted, compressed, and condensed under the restraint of true qi, instantly transforming into a thin thread of medicinal liquid as fine as a hair.

He slightly moved his wrist, and the extremely thin thread of the medicine seemed to have a spirit, slowly probing into the needle hole on Mu Pingting's arm and steadily drilling into her vein.
