"Since you all admit it, that's great. Next, let's swear, my demon clan's heart demon." Lord Fenghuo's cold voice rang in the ears of the three demon kings, making their complexions pale. It became more and more bitter.

Lin Xiu didn't have such a deep understanding of the Yaozu, and he didn't know anything about the Heart Demon Oath.

Under Master Fenghuo's explanation, he slowly understood.

It turns out that there are many kinds of binding oaths in this world. For the human race, it is to rely on formations, and then make a scroll, engrave the power belonging to the world on the scroll, and the person who made the oath will leave their own words on it. blood.

If he wants to break the oath in the future, then the person who holds the scroll can make the person who swore to pay a certain price as long as he stimulates the blood essence in it.

The monster race is not so troublesome, their inheritance is much longer than that of humans, and the coercion from the blood will make them obey the ancient curse.

The oath of the monster race is much harsher than that of the human race. The so-called heart demon oath is to engrave a heaven and earth formation in one's blood. Life is better than death.

Secretly sighed, Lin Xiu didn't have the slightest intention to stop the viciousness of this oath.

Only this method can ensure that these monsters will be loyal to him in the future and will not turn against him.

Only in this way, if they were all brought out of this world, Gui Yuanzong would accept them instead of trying to kill them all.

"I, in the name of the great blood of the demon clan, promise to follow in the footsteps of human Lin Xiu in this life, and unswervingly become his most loyal servant. If I break this oath, the world will perish!"

The voices of the three great demon kings gradually echoed in the whole world, causing an inexplicable sensation.

After the oath was completed, they all knelt down towards Lin Xiu.

"Owner."

Nodding his head in satisfaction, Lin Xiu helped them up from the ground. From now on, these people will be his team, and now it's better to stay calm.

"You guys don't need to be like this. One day when I break through to the upper three realms, I will definitely give you back your freedom." Lin Xiu still understood the principle of giving a date with a stick.

What he never expected, the three demon kings were not grateful when they heard his promise, but the bitterness at the corners of their mouths became deeper.

It is not an easy task to successfully break through to the upper three realms.

There are so many domains in the Xianwu Continent, and in each domain there are many fighters in the Tianyuan realm, but there are still very few people who can truly reach the Qiankun realm.

Lord Fenghuo's face turned slightly cold when he saw this situation.

"You guys really don't know what to do. I'm afraid it won't be long before you will be able to regain your freedom. You still have this attitude."

The three demon kings were all a little puzzled at this time.

"You know, it only took him five years to reach his current strength from the lowest level of blood refining."

It's just that they couldn't say anything, the three of them were shocked, and they knew Lin Xiu's own talent well.

But to say that breaking through to the current level within five years is tantamount to nonsense.

If it wasn't for Lord Fenghuo who said this himself, if it were someone else, the three demon kings would just listen to it as a joke.

But the pride of my Fire Phoenix clan tells them that everything that Lord Fenghuo said should be true.

They looked at Lin Xiu with a trace of sincerity at last.

If Lin Xiu can really break through to the upper three realms in the future, then following such people is not considered a humiliation of their identity, but a kind of pride.

Looking at Lord Fenghuo with some gratitude, Lin Xiu understood that the reason she said this was just to save himself the time to subdue them.

"Dare to ask the master, when will we be able to take us out of here." The golden lion king's old eyes are full of begging, his lifespan is running out, if he can't leave here, I'm afraid it won't be long before he will Died.

"You used up a lot of essence and blood before, and the damage to your body is too great. Now it's better to recuperate." Lin Xiu comforted him, and he was not in a hurry to return to Guiyuanzong now. I also want to do a good search in this world.

Unexpectedly, the Golden Lion King had a wry smile on his face at this time.

"I don't dare to lie to my master. I don't have much time. After losing the essence and blood, I have already reached the point where the oil is exhausted. I just want to take a look at the colorful world outside before I close my eyes."

Lin Xiu's heart suddenly skipped a beat. He didn't want to see his subordinates who had just subdued lose their value so quickly, so he immediately looked at Lord Fenghuo with a questioning look.

The latter nodded unobtrusively, which made his whole heart sink.

"I don't know, but is there any way to heal senior's injury?" Lin Xiu asked again with some unwillingness to give up.

"The lifespan of all things has an end. When we embark on the road of cultivation, it is a process of fighting against the sky, the earth, and ourselves. As our strength continues to improve, our lifespan will also continue to increase. Addition, it has been more than a thousand years since I broke through to the realm of Tianyuan. During this long period of time, because the Dao of heaven and earth is not complete, it is difficult for me to make any progress. If you want to continue my life, it is really difficult. Difficult, difficult."

He said three difficult words in a row, which also made Lin Xiu understand that what the other party said was not false.

But if the most powerful Golden Lion King really came to the end of his life, he would be really unwilling.

Suddenly he thought about it, his blood was already filled with endless vitality, and he wondered if it was possible to extend his lifespan for this Golden Lion King?

"Lord Fenghuo, my own blood is a little strange. In your opinion, can it solve the problem of longevity of the old man?" Lin Xiu came to Lord Fenghuo, looked at the other party's beautiful face, and waited for her. answer.

The three demon kings were also staring at Lord Fenghuo intently at this time. Lin Xiu's words rekindled the hope of life in the Golden Lion King's heart.

Each of them wanted to hear Lord Fenghuo's opinion. After all, the latter was born in the royal family of the monster clan, and his knowledge was not comparable to theirs. Maybe there were some ways to do it.

After pondering for a long time, Lord Fenghuo rubbed his temples with jade hands, and there was a trace of fatigue in his eyes.

"It seems that there is really a way."

The author, Lazy Scholar, said: There is one more chapter, everyone, don’t wait, go to bed early, I will get up early tomorrow to write, and I can’t hold it anymore...
