After surrendering Zhang Han, Lin Yu first arranged for him to move into a relatively spacious mansion in the city.

Afterwards, Long Qie was sent to send him two servants and four maids to take care of him.

After all, Zhang Han had just heard the bad news and was in a very bad mental state.

In addition, Lin Yu was not sure whether Zhang Han would regret it, so he had to have someone monitor him for a period of time.

After the arrangements were made, Lin Yu went to visit Duan Murong with the formula of Ma Fei Powder.

Although it was already late at night, Duan Murong still hadn't gone to bed.

She had just returned from the wounded barracks and was cleaning medical equipment in her room.

Arriving at the window of the boudoir, Lin Yu saw her graceful figure projected on the window.

As soon as the oil lamp flickered, the figure also swayed.

Reaching out and knocking on the door, Lin Yu asked in a low voice, "Is Miss Rong asleep?"

Hearing the noise, Duan Murong immediately walked to the door and responded:

"not yet."

"It's so late, young master, do you have anything to do with me?"

Lin Yu responded: "Yeah."

"I happened to get a prescription today."

"I want Miss Rong to see it."

Duan Murong in the room immediately opened the door as soon as he heard that Lin Yu had a new prescription.

"What recipe?"

"Let me see."

As soon as the door opened, a fragrant breeze hit my face.

I saw that Duan Murong had taken off his coat, wearing only a plain thin shirt on his upper body and only a pair of tight shorts on his lower body.

The night wind blows, and the tulle clings to the body, fully displaying the girl's graceful body, even the small outline can be seen clearly.

"This girl is really defenseless tonight." Lin Yu sighed in his heart.

Then he handed over the prescription of Ma Fei Powder.

"Miss Rong, please take a look."

Duanmu Rong took it in her hand and looked at the medicinal materials in the prescription one by one.

"Huh?"

"It's really strange. The properties of the medicinal materials in this prescription are in conflict with each other, and the cold and heat are in conflict with each other. There is no system at all."

"Young Master, what is this medicine used to treat?"

Lin Yu smiled and said:

"This is not a general prescription, nor is it used to cure anything."

"The name of this medicine is - Ma Fei Powder."

"Ma Fei Powder?" Duan Murong had never heard of it. She tilted her head and showed some doubts in her beautiful, clear eyes.

"What is Ma Fei Powder?"

Lin Yu patiently explained:

"Using this medicine, the injured person will fall into coma and lose all consciousness within a short period of time."

"He will not feel any pain, even numbness and itching."

"In this way, we can take the opportunity to treat his injuries."

Duan Murong was surprised and happy after hearing this.

She was in Pengcheng today and had been dealing with wounded soldiers.

Many soldiers were hit by arrows and needed to pull out the arrow clusters, but the process was so painful that they fainted from the pain, even struggled to dislocate the arrows and bit their tongues.

Duanmurong saw the doctor's kindness and felt very sad in her heart.

But with the help of Ma Fei Powder, these soldiers no longer have to endure the pain.

Isn't it a beautiful thing?

"Young Master, can I try the effect of this Ma Fei Powder?"

Duan Murong asked impatiently.

"Of course." Lin Yu nodded.

It happened that Duan Murong had medicinal materials in her room, so she immediately took the medicine according to the formula and fried it on the stove.

Not long after, the medicine was ready.

Duanmu Rong carefully poured the boiled hemp powder into the bowl and brought it over.

He asked softly: "Young Master, is this Ma Fei Powder for external application or oral administration?"

Lin Yu said:

"It's time to wet a towel, cover your mouth and nose, and inhale slowly."

"Then it will take effect."

After thinking about it, Duanmu Rong felt that she could better understand the properties of the medicine only by testing it herself, so she immediately said to Lin Yu:

"Then please, young master, treat me as a wounded person and anesthetize me."

After saying that, he took out a handkerchief with the girl's body temperature from his arms and handed it to Lin Yu.

Lin Yu was stunned for a moment and confirmed with her:

"Miss Rong, are you sure you want me to anesthetize you?"

Duan Murong's expression was determined:

"Of course. If I don't test the medicine myself, how can I use this medicine to treat the wounded?"

"Young Master, please don't forget to stimulate my body after anesthetizing me to see if I feel nothing."

Lin Yu was very moved after hearing this.

As expected, doctors are kind-hearted!

Since Miss Rong is so sacrificial, he won't be coy anymore!

Immediately and without hesitation, he soaked the handkerchief in Ma Fei powder, then gently picked it up, covered Duan Murong's beautiful and delicate mouth and nose, and anesthetized her.

At first, Duan Murong struggled symbolically, which made Lin Yu move a little bit.

Soon, she gradually lost consciousness, her body stopped twisting, and her arms drooped.

Seeing the completely unconscious beauty in his arms, Lin Yu couldn't help but sigh:

"How can this be testing medicine?"

"This is obviously a test of me!"

"Who among the average person can withstand this kind of test?"

He first gently picked up Duan Murong and put her on the bed.

Then he took a deep breath and told himself:

"Miss Rong trusts me so much, I can't do anything to disgrace her!"

"But since she said that she wants me to stimulate her body while she is anesthetized, should I do it?"

With a valid reason, Lin Yu gently took off Duan Murong's thin shirt and shorts.

"Dedicate yourself to medicine!"

While reaching out to press Miss Rong's delicate body, Lin Yu said to himself:

"Don't think wrongly."

"This is just a medical experiment."

"This is sacred and serious."

In order to maintain a pure heart, he decided to regard Duan Murong as a car for the time being.

His current behavior is just to perform maintenance on the car!

"Um."

"The car is about 18 or 19 years old and is 1.67 meters long."

"Open the front hood of the car first..."

"Yes, the leather interior is white and bright! It's been well maintained and is basically brand new. There's a faint fragrance in the central control room."

"The two headlights are round and straight, smooth to the touch, and the wicks are pink."

"Look further back."

"Lift the back cover."

"The chassis is stable, the outline is full, and it's very curved."

"The engine is too new and needs to be run in."

"The exhaust pipe is tight and film-coated, the entrance is butterfly-shaped, and there is no sign of loosening."

"It will automatically drain after ten minutes of posture."

"This car consumes gas at first glance, but it must be a good car!"

"If you can take it to the wild and drive it around, tsk tsk..."

After completing a full set of examinations, Lin Yu nodded with satisfaction.

Finally, I pinched the headlights, patted the chassis, and poked at the exhaust pipe.

After confirming that the car had no safety hazards, he felt relieved.

After a full hour passed, Duan Murong slowly woke up.

She stretched, sat up from the bed, looked up and saw Lin Yu standing by, and asked quickly:

"Young Master, how is the situation?"

Lin Yu replied subconsciously:

“The car is in very good condition and there are no hidden dangers.”

"Shall we make an appointment for a test drive?"

Duan Murong:???

"Young Master, are we talking about the same thing?"

"I was asking how about Ma Fei Powder?"

Lin Yu was stunned for a moment, and then he realized:

"Oh, Ma Fei San!"
Chapter completed!
