"The main thing is that because I am here, I have much stronger control over the Demon servant's mark than you, so he has no chance to resist. If I were not here just now, I'm afraid you will be in danger." Zi Tong continued.

Jiang Fei said in shock: "I really didn't expect that the sect leader was so powerful that he could find a way to restrain the demon servant's mark."

"It is impossible for him to do it just by being a person in the mortal world. I think there must be a very powerful existence behind him, so you have to be more careful in the future. If you reveal your identity, you should guess the consequences without me telling me." Zi Tong said solemnly.

Jiang Fei nodded. Now his strength is still weak. He was not worried about the Demon servant mark, but unfortunately, the Demon servant mark now has the possibility of failure. Once the identity is exposed, what awaits him will be the pursuit of the powerful man in the Tribulation Period. It is simply easy for a strong man to deal with him.

"I will be careful. By the way, this is the Yin-Yang two-generation pillar created by your brother. You should know more about it than that." Jiang Fei looked at Zi Tong with anticipation and said.

"Of course I understand, otherwise I wouldn't have stopped you just now." Zi Tong said.

"So Elder Seven is completely lying to me, why did he do this?" Jiang Fei said in confusion.

"It's very simple. He just wants you to be a sacrifice, and it's a very perfect sacrifice, because you are a fairy and demon. As long as you inject your essence and blood into the Yin and Yang pillar, it's equivalent to sacrifice your essence and blood. At that time, you will be destroyed, and he will borrow the power of your sacrifice and successfully transform into a fairy and demon. " Zi Tong said.

Jiang Fei was very scared. He thought he had mastered the life and death of the Seventh Elder, but he was eventually defeated by the Seventh Elder's plan. If Zi Tong hadn't stopped him in time, he would have almost sacrificed himself alive.

"This smelly old man is really hateful. He almost obeyed his words and let me defeat him." Jiang Fei said as he was about to attack the seventh elder lying on the ground.

"Wait!" Zi Tong quickly stopped him.

"What? Is there any use for keeping him?" Jiang Fei looked at Zi Tong in confusion.

"It's useless to me, but it's very useful to you." Zi Tong said.

"What's the use?" Jiang Fei became even more confused.

"Of course it is used as a sacrifice to help you activate the formation here, and then allow the two forces in your body to coexist." Zi Tong said.

"Coexistence? Why isn't it fusion?" Jiang Fei said quickly.

"With your current strength, it is already very good to be able to use the Yin and Yang pillars to achieve coexistence of strength. It is impossible to merge." Zi Tong said.

"Didn't your younger brother can merge the power of immortals and demons in the Nascent Soul stage? Why can't I do it?" Jiang Fei said with some depression.

"My brother had the Demon Emperor and the Immortal Emperor attacked together back then, so he could barely allow him to merge the power of immortals and demons. Now you only have the Yin and Yang pillars of birth, and your immortal cultivation is only in the Golden Pill stage, so it is already very good to be able to coexist." Zi Tong said.

Jiang Fei was immediately depressed. He had only heard of the existence of Demon Emperor and the Immortal Emperor in Zi Tong. If he wanted to ask them for help, it would be impossible to dream.

"Oh, let's coexist." Jiang Fei sighed helplessly.

"Don't be disappointed, the way of fusion of immortals and demons is profound and profound. It may be a good thing that you have not fusion now." Zi Tong said.

"Why is this? Why is it a good thing without fusion?" Jiang Fei said with wide eyes.

"Although my brother forcibly merged the power of immortals and demons in the Nascent Soul Stage back then, this made him not very well understand the power of immortals and demons. Although he was able to transfer the power of immortals and demons after he became an immortal, unfortunately he had defects." Zi Tong said.

"How can there be any defects in the power of immortals and demons be turned on each other? You must know that once the two forces can be turned on each other, it is equivalent to having a continuous source of power. What defects can there be?" Jiang Fei said in confusion.

Jiang Fei thought that the two forces could be transformed together, just like the way of yin and yang, which could complement each other and not be able to be flawed.

"Don't forget that the power of immortals and demons is mutually restrained. My brother forced himself to merge back then, so the power of restraint cannot be completely removed at all. Therefore, when the two forces rotate together, he will always be backfired. That's why he created this Yin and Yang two-generation pillar in order to completely eliminate the power of restraint." Zi Tong said.

"Then did he succeed?" Jiang Fei asked curiously.

Zi Tong shook her head and said, "I don't know this either, because the Yin-Yang two-generation pillar was created shortly after it was created, and he disappeared. I still don't know where I went. I have been searching for a long time but haven't found him. Maybe he has fallen."

"How is this possible? He is a strong man of the Immortal Level, and he is also a body of immortals and demons. How could he die?" Jiang Fei said.

"Who can tell everything in this world clearly? Not to mention that he is just an immortal master, even the supreme immortal emperor will eventually die." Zi Tong said a little lonely.

Jiang Fei sighed, thinking that this was really hard to explain, otherwise the Demon Emperor would not have fallen back then. You must know that he is a supreme powerhouse, an existence that is even stronger than the Immortal Emperor.

"I wonder if I will have that kind of defect in the future." Jiang Fei sighed.

"Now you take it step by step, slowly understand it, and then rely on your own strength to merge, there will be no such defects." Zi Tong said.

"Why are you so sure?" Jiang Fei said.

"This is what my brother told me back then, so after your two forces can coexist, I hope you can slowly understand and combine them with your own power, instead of relying on external forces." Zi Tong said.

Jiang Fei nodded and asked, "This Yin-Yang two-generation pillar is so powerful that it can create a person with the same body of immortals and demons. Why didn't you need him to create a few people back then?"

"I think you misunderstood. The Yin-Yang two-generation pillar cannot create a person with the same body of immortals and demons." Zi Tong said.

"Then why would the Seventh Elder say yes? And you said just now that once I sacrifice myself, he will become a person of immortals and demons." Jiang Fei said in confusion.

"My brother just said this back then, but it was actually impossible. The Seventh Elder didn't know. The reason I said that just now was because you are a person of immortals and demons. Once you sacrifice to the Seventh Elder, you can inherit your power, so he will also become a person of immortals and demons." Zi Tong said.

"So that's it." Jiang Fei suddenly realized.
