"The secret skill of exchange transfusion may succeed or kill him directly. The biggest disadvantage of the secret skill of exchange transfusion is that the mind will be affected after exchange transfusion. The light one will lose his heart, and the heavy one will be possessed by the devil. That's why it's listed as a forbidden skill. I don't know what the predecessors know?" Song Tianxuan continued.

This is what he happened to see in the book in his previous life, but he didn't expect to use it here.

"What are your accomplishments? What kind of accomplishments are those doctors? Why do I believe them or not? " Nie Sifeng said with a smile.

Song Tianxuan didn't worry. He replied, "because I can cure him."

Nie Sifeng felt that there were not many doctors in the field in ten years, but he also found a lot of them, but they were helpless. How could he be cured?

What song Tianxuan said is not a lie. Huaxueshou is nothing more than turning blood vessels, muscles and bones into blood. It's similar to another kind of poisonous gall called huaxuedan of the human race. He just got the Dan prescription in the hands of Qi Master Yi Yun, so he can understand it naturally. He just doesn't know what's the difference between the two, so he must have a difference in use.

"If I guess well, you should only have one year. The side effects of exchange transfusion ban are not so bad. I don't know who provided it? Is it within the clan or outside the clan? " Song Tianxuan's face was dignified and serious.

Seeing that Nie Sifeng didn't answer, he continued to ask, "if my prescription can cure the young master, it's naturally good. If it can't cure him, it's all panacea. Naturally, it won't do any harm to the body. At that time, if the elder wants to exchange blood, it's not too late." Song Tianxuan kicked the ball back to Nie Sifeng's feet.

Two options, medication, had to not bad, medication fruitless, and then exchange blood not late, but the side effects have told you, what can be like, their choice is good.

For a moment, Nie Sifeng was in a state of confusion, and all kinds of things in the past were still in his mind... "Father..." at this time, the young man appeared at the entrance of the attic stairs, holding the handle of the stairs, looking very weak.

Nie Sifeng a flash, has been to the youth side.

There was not a trace of blood on the boy's face. He looked up at Nie Sifeng, who was full of vicissitudes. He couldn't bear it and fell on his knees with a plop.

Nie Sifeng and song Tianxuan were both surprised. They never thought that he would be like this.

The boy raised his head slowly, his eyes were moist, his voice choked and said: "father, I know that my illness was lifeless three years ago, and I'm satisfied to live till now. The forbidden technique will ruin my father sooner or later, and I don't need it."

Nie Sifeng was moved. He lowered his body and gently wiped the tears on the young man's cheek with his dry and trembling right hand: "my son, it's all my father's fault. It's all my father's fault. If I had stepped into that half step ten years earlier, I would have a way to save you."

"No, it's a forbidden skill. People who use it want to hurt the enemy and themselves first. Didn't you find that you couldn't find the person who used it that year?" Song Tianxuan shook his head.

Nie Sifeng suddenly realized that the first person he wanted to kill was the huaxueshou, but he didn't find it for ten years, and he had never seen another huaxueshou. So it is, there are only two people left.

"Father, do you want to see a child who has lost himself?" The boy choked and said, "I'm no longer mine, and I'm no longer my father's child. How can my mother rest in peace? Even if the child is dead, he has no words to say goodbye to his mother and father... "

Finally, father, father and son are already holding together, with tears streaming down their faces.

Nie Sifeng is heartbroken. He thinks of his dead wife and himself. Is he still him?

No, he's changed. He's not what he was ten years ago... "OK, you can take medicine, but..." after a long time, Nie Sifeng got up, helped the boy up and said to song Tianxuan.

"Don't kill him. It's my life to cure him. It's also my life to cure him. Why bother others?" Young suddenly interrupted Nie Sifeng's words: "this is my first choice since I was born, and it's also my first time to ask you."

The implication is clear.

Song Tianxuan was also moved by this scene. He had been on Mo Yunxing since he was a child. How could his parents not move him now?

Looking at the boy, Nie Sifeng nodded his head meaningfully and turned to look at Song Tianxuan: "well, this is my son's creation for you. If I don't kill you, I'll give you Fenglei wings. If it's cured well, the human relationship will be yours. If it's not cured well, it will be written off."

Song Tianxuan's worship is not only his trust in Nie Sifeng, but also his admiration for the young man. At such an age, he has seen through life and death and is compassionate. If he can practice, his future will be limitless.

"The younger generation is easy to rain, so we should do our best." Song Tianxuan bowed his head.

"Well, ten days later, it's the engagement of Qingfu. I have a reason with the North general, and I'm in love with Qingfu. Since I stayed here for some time, when do you think it will start?" Nie Sifeng said.

Song Tianxuan raised his head. He had just won the wings of wind and thunder. In the later stage of Lingtai, he also needed to strengthen his cultivation. The power of the dragon and the elephant is showing signs of breaking through the second level. The method of Maoshan also needs to be strengthened. It's better to stay in Qingcheng and have the protection of Nie Sifeng. Naturally, he can be quite stable.

"Naturally, the sooner the better. I'll make a diagnosis for you now." Song Tianxuan said and went upstairs.

The three entered the master bedroom on the second floor, and song Tianxuan put his hand on the young man's pulse.

His pulse was steady, but very weak. He could clearly feel the sticky smell in the blood. The aura was infused into song Tianxuan's body, but he felt surrounded by the blood and ate directly.

"This blood has the ability to swallow aura." Song Tianxuan was shocked.

"Yes, that's the power of the bloody hand. Even Xuanli can't help it." Nie Sifeng said helplessly.

Song Tianxuan had a flash of inspiration. One of the antidotes of huaxue Dan was Zhenlei powder. Zhenlei powder was ground by the medicinal materials with the property of thunder. It had the instinctive smell of heaven and earth God thunder. I don't know if it had any effect on it.

And Yi Ziqi said that nine days thunder fire bamboo has a very important effect on suppressing evil Qi. It's a forbidden skill to melt blood hand. I don't know if it belongs to the category of heresy?

Song Tianxuan pondered for a moment, and the thunder suddenly appeared on the platform. There was a ray of thunder in the aura, which was introduced into the body of the boy along the meridians.

Since the promotion to Lingtai, Lingtai has absorbed the power of thunder, and now it can be completely controlled by song Tianxuan.

Although it's just a trace, it's still very dangerous for an ordinary young man. Song Tianxuan had to wrap it with aura. After the blood devours the aura, the thunder burst out in his blood.
