Li Mao took Qingxu's master and apprentice into the palace and came to a well-guarded dark mansion in the backyard.

As soon as I entered the door, I saw an old man who looked like an old housekeeper, and hurriedly greeted him with two young men in green robes.

"How about the prince, have you invited Danshi?"

"Please, these two behind this king are the Qingxu Dao Master and his disciples, and the Dao Master is a Dan Dao master.

Only then did the three of them realize that the two people who followed behind Li Mao, facing a noble Dan Master, they didn't dare to slack off, and hurriedly bowed down to greet them.

"I've seen the Qingxu Dao Chief. ”

Qingxu waved his hand, "No need to be polite, take Poor Dao to meet the old county king, whether it can be cured or not, you have to check it yourself." ”

"Dao Chief, please," Li Mao didn't dare to procrastinate, bowed slightly, and personally brought everyone into the inner hall.

Fang entered the hall, a refreshing cold air hit his face, and the frightened rest of his life hurriedly resisted, Qingxu frowned, looked up inside, and saw a white-haired old man sitting cross-legged in the hall, although the room was surrounded by a burning red bronze stove, but the old man's hair was still covered with frost, and a cold air visible to the naked eye faintly emerged from the top of his head.

"The situation seems to be much more serious than what the county king said?" Qingxu glanced at Li Mao with some dissatisfaction, and he only said that he was unconscious in the inn, but he did not say that the cold had dispersed so seriously.

Li Mao didn't seem to know anything about this, he hurriedly called the palace housekeeper on the side, "Old Wang, what's the matter? When this king went out, his father was just in a coma, why did he become like this in less than two hours?"

Lao Wang was nervous for a while, he didn't know how to answer, not long after Li Mao left, Li Zhen's cold poison suddenly began to attack, the medicinal materials used to suppress the cold poison in the past few days did not work at all, the pharmacists sent by the two emperors tried many times but there was no way, but fortunately, the young pharmacist on the side spoke in time, which relieved him.

"Lord Wang, this matter has nothing to do with Steward Wang, he doesn't understand this, the cold poison in the old prince's body suddenly broke out, it is indeed a bit unexpected, this is not the time to investigate the problem, it is better to ask Master Dan to go first to heal. ”

When Li Mao heard him say this, he suddenly realized that he couldn't bother with these anymore at this time, and hurriedly bowed down to Qingxu and apologized, "This time it was really sudden, and I hope that the Taoist is not strange, although the Dan master has made a move, after the matter is completed, there will be another thanks." ”

Qingxu ignored him, his eyes were still staring at Li Zhen and frowning, this kind of cold poison seemed to be a little familiar to him, and after a while, his eyes lit up, as if he remembered something, and then he turned to look at Li Mao.

"Sure enough, it's not an ordinary cold poison, the poor Dao is not a greedy person, you just need to fulfill your previous promises. After that, he patted the little head of the rest of his life behind him, "For the rest of your life, you will stay here with the king of the county, and wait for the teacher to come forward to verify it." ”

Yu Sheng nodded obediently.

Qingxu stepped forward with a calm face, and after approaching Li Zhen, he stretched out his finger to probe his eyebrows, the two young pharmacists wanted to speak again when they saw this, they didn't know the level of Qingxu's grade, this kind of cold poison was too terrifying, they didn't dare to approach, and they were worried that Qingxu would put himself in, but at this time, Li Mao was by his side, it was a matter of life and death for the old county king, they didn't dare to open their mouths to advise, they could only pray that Qingxu was fine.

Qingxu's fingertips have not touched Li Zhen's forehead, the cold air spreads along his nails to his palm, and his fingers instantly form ice crystals, and the rest of his life is nervous, his worried mouth opens wide, and he is about to shout to be careful, but he sees Qingxu's fingers trembling slightly, and after a slight click, the cold seems to have encountered something terrifying, and quickly retreats, and when Qingxu's fingers touch the skin in front of Li Zhen's forehead, the cold still recedes to both sides, and the skin around the fingers slowly becomes ruddy.

Closed his eyes and pondered for a moment, nodded clearly, and turned his back to the corners of everyone's mouth with a chuckle, and secretly said that this was the case, but he was slightly surprised, it stands to reason that this kind of thing should not appear in this land, it seems that the secret place where Li Zhen and them went is not simple.

Li Mao and the others behind him couldn't see the expression on Qingxu's face, but they could see the changes in the skin on Li Zhen's forehead clearly, and when they saw that Qingxu seemed to be able to restrain the cold poison, their hearts were slightly relieved.

Retracted his fingers, exhaled the cold air, Qingxu's face returned to calm, turned around and walked towards everyone, and the cold air on Li Zhen's forehead quickly condensed.

Li Mao and the others hurriedly stepped forward, "Dao Chief, how is the situation? Is there a way to save my father?"

Qingxu nodded, "Fortunately, it came in time, there is still a way, but the county king needs to prepare some medicinal materials, and after a while, the poor Dao will use the power of Danhuo to force out the cold poison for the old county king, and when the cold poison is separated from the body, a dose of decoction is needed to warm the damaged meridians in time, so as not to leave a secret injury." ”

Li Mao and the others took a long breath, "I don't know what medicinal materials are needed, when the two of us came, we brought a lot of precious yang attribute medicinal materials from the palace, and the palace also had a lot of inventory." ”

Qingxu nodded slightly, "Don't worry, these medicinal materials are not rare, I wonder if the two pharmacists can know the 'Yang Vein Soup'?"

The two young pharmacists nodded hurriedly, and the pharmacist on the left spoke: "I know, the two of us have also given the old prince a lot of this yang vein soup in the past few days. ”

"That's very good, you two go and boil a bowl faster, and you can force out the cold poison in his body in half an hour, and then you can give him the yang vein soup. ”

Li Mao heard his instructions and hurriedly asked the two pharmacists to go down to prepare.

After the two pharmacists left, Qingxu returned to Li Zhen's side, sat cross-legged behind him, poked out his left hand, and directly attached his palm to the back of his head, the spiritual energy in his body turned into Danhuo, and entered his body along Li Zhen's meridians, the cold qi retracted downward from the top of Li Zhen's forehead at a speed visible to the naked eye, and retreated to his neck in less than half a pillar of incense time, Qingxu put his right palm on Li Zhen's back, and at the time of tea, the ice crystals on Li Zhen's body turned into a puddle of clear water, his face changed from pale to red like fire, his mouth opened slightly, and a stream of cold gas continued to pour out of his mouth, exuding water vapor all over his body, but the front of him was strangely covered with frost。

Yu Sheng stood on the opposite side and watched this scene in amazement, while Li Mao clenched his hands nervously, his finger joints turned white, and his fists kept trembling.

For almost half an hour, two pharmacists walked in with a bowl of steaming medicinal soup, and when they saw that Qingxu was still healing Li Zhen's injuries, they stood quietly and watched, not daring to disturb.

After the tea again, I saw Qingxu snorting, his shoulder moved slightly, and pressed the right palm on Li Zhen's back to push violently, Li Zhen opened his mouth "wow", spit out a piece of bloodshot and cold crystal, his body leaned back softly, his complexion gradually returned to normal, Qingxu held his body, beckoned to a few people, and waited for the housekeeper to understand, and hurriedly stepped forward to support Li Zhen, Qingxu then stopped.

Seeing this, Li Mao and the two pharmacists quickly stepped forward, intending to ask about the situation.

Qingxu ignored them, got up and walked to the crystal and squatted down, wrapped his palm with spiritual power, and pinched the fingernail-sized crystal that Li Zhen spit out on the ground, and the spiritual power moved slightly, removing the blood on its surface, revealing its snow-white and crystalline body.

For a while, the temperature in the hall dropped rapidly, and the three Li Mao, who were frightened and stepped forward to ask, hurriedly dodged and retreated, and saw a small jade bottle suddenly appear in Qingxu's palm, and then carefully put the cold crystal into the bottle.

Li Mao's eyes were slightly condensed, and he glanced at the Na Ling Ring between Qingxu's fingers with a complicated expression, he had heard of this kind of mysterious storage treasure, in the entire Tang Empire, he had only seen one in the hands of the emperor.

The two pharmacists on the side didn't notice the strangeness in Li Mao's eyes, and after seeing that Qingxu had finished dealing with the cold crystal, they stepped forward and asked urgently, "Dao Chief, how is the old county king?"

"The cold poison has been forced out, quickly give him the Yang Vein Soup. ”

The two potions didn't dare to slack off, came to Li Zhen with the medicine bowl, gently pinched his jaw, waited for his mouth to open wide, and slowly poured the medicine into his mouth, until the bottom of the bowl was clean.

"Help him to rest on the couch, he will be able to regain consciousness in about three hours, and in the next half a month, give him two more doses every morning and evening, and his body will be fine. ”

Li Mao and Steward Wang helped Li Zhen onto the bed one left and one right, and the pharmacist on the side saw Qingxu sitting cross-legged in front of the hall with his eyes closed, so he took the opportunity to hold Li Zhen's wrist and gave him a pulse, and after a while, he nodded at Li Mao with a happy face, and Li Mao turned his gaze to Qingxu's master and apprentice, and the tense heartstrings finally relaxed.

Yu Sheng, who was standing behind Qingxu, naturally saw their small movements in his eyes, and pursed his lips with disdain.

Seeing this, Li Mao smiled awkwardly with his old face, turned around and asked the housekeeper to entertain the Qingxu master and apprentice, and he hurriedly walked out.

When Li Mao returned with a purple gold plate covered with red cloth, Qingxu had already opened his eyes and was sitting there with a tea bowl, coping with the compliments of the two pharmacists without saying a word.

"Thank you for your life-saving kindness. ”

Li Mao said, lifted the red cloth on the purple gold plate with a complicated face, picked up a herb with a fire all over its body, and a lifelike fiery red flower on the top, handed it to Qingxu's hand, and pointed to the four items on the plate with a distressed face.

A crystal clear gem, there is a drop of bright red liquid glowing with golden mangs in the middle of the gem, it seems to be surging constantly, next to the gem is a palm-sized animal skin, the animal skin is painted with strange patterns, shaped like mountains and ravines, and on the other side there are two cheats, one covers says "Xuanyang Finger", and the other reads "Agni Gong", which should be the two local level intermediate cheats he said before.

"This is the reward promised to the Taoist before going down, this medicinal herb is the four-grade medicinal herb Yang Linghua treasured in the mansion, and the other four are the four treasures that my father brought out from there, and the Taoist can choose any two. ”

Qingxu picked up the Yang Spirit Flower, sniffed it at the mouth of his nose, and then nodded with satisfaction, and put it into the Spirit Ring, but he didn't look at the plate again, but turned sideways and looked at the rest of his life, "For the rest of your life, which two of these four items do you think you should choose as a teacher?"

Everyone in the room was surprised to set their eyes on the rest of their lives, the four items on the plate, no matter which one is not simple, especially the two local level intermediate cheats, which are considered to be treasures in the entire Tang Empire, once they enter the Dao realm and start cultivating, according to his qualifications, they will be able to enter the Ning Dan realm within a hundred years and become a master admired by hundreds of millions of people in the empire, but they didn't expect Qingxu to dote on this little apprentice so much, and handed over the choice to him, and the two pharmacists were full of envy, this little guy is the blessing of several lifetimes, so that a Dan master of not low grade can be so valued。

Yu Sheng saw that his master seemed to be chuckling, but his eyes were sincere, and he secretly said in his heart, with his own master's eyes, he may not take these things in his eyes, it seems that he really gave the choice to himself.

But he didn't know that this was a test for him by Qingxu.
