"Did you say about blood essence?" Song Tianxuan raised his head and wiped the blood from the corner of his mouth.

Nie Sifeng nodded: "yes, since you are not a doctor, according to the previous agreement, I will take your essence and blood, but I won't hurt your name. Later, I will take you back to my Shendiao family. You will recover as before in five years, and you will get wind and thunder wings. You still earn money."

"The essence and blood is the essence. I don't know how to ban it? Can you... "Song Tianxuan carefully looked around, but he was not at ease.

After a fight, who knows that the prohibition is not as strong as it was before?

Nie Sifeng looked at Song Tianxuan suspiciously. With a wave of his right hand, he hit out a magic formula. A gray light flashed out and shot into the attic, which instantly turned into a gray mask and covered the interior of the attic.

"Well, don't worry." Nie Sifeng is not afraid of this young man's tricks. He has absorbed the essence and blood of the divine carving family. It's not difficult to break through to the later stage of Lingtai. His cultivation has reached the peak of Xuantong. Even if the golden winged Marquis comes, he has to weigh it, let alone a little hairy boy.

But song Tianxuan was smiling: "the elder is wise. Just now, the younger generation also said that the essence and blood is fundamental, and the elder doesn't know it. If I guess it right, the elder uses my essence and blood to replace it by force."

Nie Sifeng was shocked as if he had set off a storm in his heart. The method of exchanging blood was a secret skill. How could he guess it as a teenager?

"Look at the look of the elder. Unfortunately, I was guessed right by the younger generation?" Song Tianxuan didn't dare to talk nonsense. Others called him a gentleman. In case he killed himself, and God carving's essence and blood backfired, no one would doubt anything.

Nie Sifeng nodded difficultly: "you know a little more."

In an instant, a powerful pressure burst out directly, and then it was forbidden by the stable system, flashing gray light, as if it would be broken at the next moment.

However, song Tianxuan was so shocked that he half knelt down on the ground. He secretly called for regret in his heart, but he said in a hurry: "if you are wrong, it's not too late to kill you."

Nie Sifeng pondered for a moment. The young man had just received the wings of wind and thunder. According to his performance, he should be the proud generation of the golden saint ape group. Now he told the secret of blood exchange. If he killed him and directly took the blood essence, the golden saint ape's two brothers, one is missing, the other and his short guard. If there is any accident, the gain is not worth the loss.

"Good." Nie Sifeng received Xuan way: "you'd better say one, two, three, or you're even a golden saint ape group, I'll kill you today."

The secret skill of exchanging essence and blood was originally forbidden. If it was spread, his gentleman fan would be shameless, and the divine carving clan would take the others to the bottom of the cliff.

Think of here, just press the idea that killed song Tianxuan.

"Thank you, master." Song Tianxuan struggled to stand up, but he could not move. His feet were as heavy as lead.

Between a thought, between life and death.

Song Tianxuan gasped heavily, and the suppressed aura in his body quickly repaired the injured meridians and bones.

"Exchanging blood books is a forbidden book. Whether it's in the demon clan, the Terran clan or the Tianhe silver sea, the elder is known as a gentleman and has a good reputation, but he still has to choose to use this kind of forbidden technique. He must be forced to do so, but there is a huge disadvantage of exchanging blood. I don't know whether the elder knows it or not?" Song Tianxuan pondered for a moment and asked. His eyes were clear without any impurities.

Nie Sifeng couldn't help frowning. Today, he was shocked enough. How much did the young man know?

Seeing that he was speechless, song Tianxuan said with a smile, "as you can guess, why did I ask the elder to reinforce the ban?"

"Because you are a doctor, but you don't want to expose it. You can only say it when you are sure of the success." Nie Sifeng suddenly said, which he just thought of.

There are not many people who can associate blood essence with secret exchange transfusion. After visiting so many doctors, there are only a few people who can think of it, but the young people in front of them think of it.

"Are you not afraid that I will expose you?" Nie Sifeng suddenly said with a smile.

Song Tianxuan felt that he had cleared a point on his leg and immediately said with a smile: "first of all, the elder is a gentleman. How can a gentleman reveal secrets? It's just villains who leak secrets. Second, I can't do it, because I've got wind and thunder wings. If the prescription doesn't work, you still need to use my essence and blood. How can you provoke those unnecessary troubles? "

"Ha ha, it's a deep plan to be young. If I had your heart at your age, I would not be at the present stage." Nie Sifeng gave a smile, as if falling into the memories of the past.

"I just don't know where your illness came from? I need a detailed process. " Song Tianxuan turned and pointed to the attic.

Nie Sifeng's smile also solidified and pondered for a moment. He affirmed song Tianxuan's childe. Besides his own flesh and blood, who would take out such treasures as wind and thunder wings in exchange.

The wind and thunder wings were bought by him for his life. Now there is no further achievement in his cultivation. It is for this thread of vitality.

"He is my child. Twelve years ago, I married his mother, and the next year I had him. I had to quit the world and live a life of peace with her, but the day before he was born, I was still found by my enemy. I didn't protect her well. She was seriously injured and gave birth to a child."

"I tried my best to break through the encirclement, and took her mother and her son out of the encirclement. Ten days later, his mother was over consumed and seriously injured. After breaking through the encirclement, she left, and I began to revenge. In ten years, there were only three people left."

"But later, I found out that their real goal was not my wife and I, but our children. I thought that only Xuanli could repair his meridians. But when he was three years old, his condition suddenly deteriorated and he was forced to disperse all his accomplishments. I searched for doctors for ten years and found that the disease was a blood melting hand, a secret method, The more blood channels turn, when I was eight years old, I should have died, but I used my blood essence to get into it and save my life. "

"By chance, he got the secret method of changing blood essence. As long as he changed blood essence all over his body, the blood melting hand can be relieved. But he is the blood of the divine carving clan. How can our clan sacrifice the clan to save a dying man?"

"And we can't let the clan know about the forbidden technique of exchange transfusion. So the elders will use their own essence and blood to let others absorb, so that the essence and blood in the body will contain the breath of the God carving family, and the discipline of success will be greater. " Song Tianxuan said.

From what Nie Sifeng said, he has roughly understood the process of injury. Although it is only about, it is enough. Although he has never heard of the bloody hand, it is a very insidious mystery from the power point of view.

This man clearly wants this gentleman to have no sons or grandchildren

Nie Sifeng nodded and admitted what song Tianxuan said.
