In the wing room of Tianxi Building, at this time, there were only four people, Bai Na, Yuan Ping and Yun Fan.

After Wan Guiyi hoped that Yuan Ping could treat Bai Na as soon as possible, he took the two upstairs, and Yun Fan, as Yuan Ping's only disciple, naturally accompanied Yuan Ping's side.

As for the rest of the Unified Cultivation Group, they were still waiting downstairs.

"The old man began to treat the deputy head of the regiment, and asked the head of the regiment to wait outside the house. After Yuan Ping placed the jade box containing the purple mansion phoenix returning grass on the table, he turned to Wan Guiyi and said.

"Huh, can't I stay?" Wan Guiyi was slightly stunned and asked.

Although Yuan Ping would also retreat when he treated the injuries of the members of the group before, this time it was about Bai Na, which made Wan Guiyi a little reluctant to leave.

"Commander, this is the doctor's rule, when treating the disease, no outsiders can be present, and ask the head of the regiment to wait outside the house......" Although Yuan Ping's tone was not tough, his attitude was very resolute, which made Wan Guiyi feel a little embarrassed.

"Normalization, this is the doctor's rule, you don't want to embarrass Yuan Lao......" Bai Na said in time when she saw this, "With Yuan Lao treating me, aren't you still at ease?"

Then he gave Wan Guiyi a reassuring look.

Seeing this, Wan Guiyi understood what Bai Na meant, when Yuan Lao was in the group, although he seemed to be approachable, he actually had his own principles, maybe this was the innate pride of the gentlemen of the four academies.

"Of course, I'm very relieved about Yuan Lao...... Wan Guiyi smiled, "Okay, I'll wait outside the house...... Is that Yun Fan ......?"

Yun Fan secretly pondered in his heart when he heard this, this ten thousand is one but his heart is very suspicious, since he doesn't believe in Master, he naturally won't believe me......

"No need to ......," Yuan Ping replied, "Since Yun Fan is an old disciple, there is no need to avoid ......."

You masters and apprentices don't need to avoid it, but I have become an outsider...... Wan Guiyi was a little embarrassed, so he could only reply stupidly, "Okay......"

After saying that, Wan Guiyi left the house with a deep frown, and the strong wind brought by his body directly closed the door of the house.

After retreating Wangui Yiping, only Yuan Ping, Yun Fan and Bai Na were left in the house, and Yuan Ping walked to his medicine box and picked something from it.

Yun Fan glanced up at Bai Na, but found that she was already sitting quietly on the bed at this time.

At this time, Bai Na's expression was as indifferent as before, and she did not show any strange emotions because of the departure of Wan Guiyi, and the huge softness on her chest was still about to come out in the white snow skirt, Yun Fan only glanced at it, and then turned his head directly to look elsewhere.

"Master...... The disciple's current medical skills are still shallow, is it better to avoid them first......" Yun Fan said, unconsciously he was a little nervous at this time.

"Fool, don't you cherish such a rare learning opportunity, why do you still think about ......avoiding it" Yuan Ping didn't turn his head to pay attention to Yun Fan, still continued to prepare in the medicine box, "No matter how many theoretical medical classics there are, they can't be as rewarding as watching and hearing on the spot, and you can still be a teacher's helper here......"

Yuan Ping said, and finally took out a few medicine bottles of different colors from the medicine box.

Picking out a white medicine bottle from it, Yuan Ping gently dissolved the powder of the medicine bottle in the tea cup, and then brought it to Bai Na's bed.

"Deputy Commander, this medicine can relieve pain and calm the nerves, and after drinking it, we can start treatment. Yuan Ping said to Bai Na.

Bai Na nodded, and without hesitation, she drank all the medicine in the teacup.

The medicine in the teacup worked very quickly, and after just a few breaths, Bai Na collapsed on the bed and fell into a deep sleep.

"Master, deputy head of the regiment, she ......" Seeing that Bai Na fell asleep in a moment, Yun Fan was also taken aback, so he asked softly.

Yun Fan knew that although Wanguiyi was outside the house, his spiritual sense was always paying attention to the inside of the house, and if there was any abnormal sound in the house, Wanguiyi would naturally know it as soon as possible.

"This medicine is called Shen Li Drunken Dream, which is one of the most commonly used anesthetic medicines by doctors, and the main ingredients are composed of Phantom Grass, Jushen Incense, Yiqi Qin and a little Shen Zui San. Yuan Ping explained.

"Anesthetic?" Yun Fan asked suspiciously.

Although Yun Fan had never heard of Yuan Ping's "Immerse Himself in a Drunken Dream", Yun Fan had seen one of the ingredients, Phantom Spirit Grass.

When he was in the Northern Desert, in order to make Yin Dagang, who was seriously injured and waiting to die, return to the light, Zhang Shenyi, the doctor in the group, used a large amount of phantom grass to wake up Yin Dagang, because this phantom grass accelerated Yin Dagang's death to a certain extent, so Yun Fan couldn't help but feel a tense heart after hearing its name, and he couldn't understand when this phantom spirit grass became one of the ingredients of anesthetic.

Yun Fan naturally didn't know that although a large amount of Phantom Spirit Grass would cause the nerves of the person who consumed it, it would even cause it to die. However, a small amount of Phantom Spirit Grass has the effect of calming the nerves and invigorating qi, and most of the other medicinal herbs have the same effect, but the small amount of intoxication powder can make the user's limbs weak and completely lose their ability to resist.

Because of this drunkenness, Yun Fan is actually no stranger, because it is an important ingredient used to prepare the poison of the drunken agarwood in Li Ruonan.

"Not bad......," replied Yuan Ping, "within two hours of taking this medicine, the person taking the medicine will be completely unconscious, and will not even feel any pain." ”

"I see...... Yun Fan nodded thoughtfully.

"Fan'er, you stretch out your hand. Yuan Ping said to Yun Fan.

"Ahh......h

"You are calm now, you must be free of distractions...... Yuan Ping stretched out his right hand, held Yun Fan's right hand and said, "Feel the qi coming from the master's hand, use your mind to try to guide it......"

Yun Fan closed his eyes and felt the slightest warmth coming from Yuan Ping's palm, but he didn't feel what the "qi" that Master was talking about.

In a moment, an indescribable strange feeling came from Yun Fan's palm, making him subconsciously want to withdraw his right hand, but he was suddenly held tightly by Yuan Ping.

"Calm down!" Yuan Ping snorted softly.

Yun Fan hurriedly gathered his mind and endured the strange feeling, which seemed to be warm but not warm, and it seemed to be itchy but not itchy, which made Yun Fan feel extremely uncomfortable.

Yun Fan's mind was in a hurry, and according to what Yuan Ping said, he wanted to try to guide this feeling.

Slowly, Yun Fan only felt that this strange feeling seemed to be slowly wrapped around his palm like a ribbon under his own guidance.

At this moment, I only heard Yuan Ping burst into tears:

"Burn!"

Yun Fan only felt that the warmth suddenly turned into a coolness, and he opened his eyes accordingly.

Yun Fan looked at his palm and couldn't help but widen his eyes, because at this time, his right hand was the same as Yuan Ping's, surrounded by an ice blue qi.

The air swayed at will, looking like an ice-blue flame.

"Master...... Is this ......" Yun Fan asked in surprise.

Yuan Ping looked at the air flow above Yun Fan's right hand, nodded with satisfaction and smiled,

"That's it...... The Phantom Hand Knife!"
