Although there are still some old monsters in the Purple Rainbow Gate, the Purple Rainbow City Lord knows that they are not good at detoxification, especially the terrifying existence of demonic poison.

Not to mention......

The demonic poison in his sister, no one in the Purple Rainbow Sect knew about it.

I don't even know the poison, how can I detoxify it.

When Qin Yi heard this, he just smiled and said, "Okay." After a pause, "Now there is only one way to save her." ”

"Say!"

The Purple Rainbow City Lord said without hesitation.

"Exchange blood."

Qin Yi said seriously.

"Transfusion?"

It's not that the Purple Rainbow City Lord hasn't thought of this method, but the bloodlines of him and his sister are relatively special, and it is not so easy to change, and the toxins in the blood are always the biggest problem.

A life for a life?

This was the only thing that the Purple Rainbow City Lord thought of.

In fact, he had already thought of this method, and he planned to make a last effort when he had to do it outside.

The chance of success in blood exchange is too slim, only less than one percent.

If he fails, his sister will die.

Otherwise, the Purple Rainbow City Lord would have done this a long time ago, without waiting for Qin Yi to remind him.

"My blood exchange is different from yours."

Qin Yi could easily see the Purple Rainbow City Lord's worries and explained, "I plan to exchange blood for the second time. ”

"Second transfusion?"

The Purple Rainbow City Lord was very incomprehensible.

"You are brothers, and there shouldn't be any problems with a short exchange of blood."

Qin Yi explained: "You exchange blood with her first, and then I will borrow you a flame to burn the poison in the blood, and finally you exchange it with her again." ”

After a pause, he thought for a moment, didn't intend to hide anything, and said, "However, this is only to save her life temporarily." ”

"Huh?"

The Purple Rainbow City Lord thought about it seriously, and probably understood Qin Yi's intentions, but he knew that if the demonic poison in his sister's body could be burned, he wouldn't have to wait until today.

"Your flames, of course, can't do it."

Qin Yi smiled faintly and said, "Use mine." ”

With that, he raised his big hand, and a red flame appeared in his palm.

It is Jiuyang Tianhuo!

"It's ......"

The Purple Rainbow City Lord had never seen the Jiuyang Heavenly Fire, so naturally he didn't know, but he had heard that Qin Yi had unleashed several powerful flames at the Four Desolations Sect Martial Arts Competition.

Even so, the Purple Rainbow City Lord could clearly feel that the crimson flame in Qin Yi's palm was extremely domineering and powerful.

The moment the Jiuyang Heavenly Fire appeared, the sister of the Purple Rainbow City Lord had a strong reaction.

To be more precise, it should be the Seven Veins Demon in her body that has reacted.

For a long time, Jiuyang Tianhuo can be described as the nemesis of the demon race.

Especially to restrain the venom.

Except for a very small number of demonic poisons, they can withstand the Jiuyang Heavenly Fire.

And the Seven Veins Demon is not among them.

"Good!"

The Purple Rainbow City Lord is a person who understands things, even if he doesn't know what the flame in Qin Yi's palm is, he knows that it is not an ordinary flame, and it is really possible to burn the Seven Veins Demon.

"Now, then."

Qin Yi smiled knowingly.

"Hmm."

Before the words fell, the Zihong City Lord's heart moved, and his sister floated up from the sealed coffin.

Blood exchange, in the Heavenly Saint Continent, is a very simple matter.

Qin Yi knew that if it was in the Earth Era, it would indeed be a bit troublesome, but in the Heavenly Saint Continent, there was such an incredible power as True Yuan, which ensured that the blood was not well contaminated by the outside world, and there was no need for a pipe or anything, let alone sterilization or something like that.

After that, the Zihong City Lord grabbed his sister's jade hand, and a blood mark appeared on the palm of his hand.

Seeing this, Qin Yi also stood aside quietly.

The Seven Veins Demon is indeed terrifying in the Heavenly Saint Continent, but among the demons, it is just a small poison, and if you really want to solve it, it is actually not difficult at all.

The only difficulty is to ensure that the soul is not corroded by the Seven Veins Demon.

And this is something that is difficult for humans to do.

However, with Jiuyang Tianhuo, the Seven Veins Demon had no chance to play at all.

Less than ten breaths in time.

The Purple Rainbow City Lord let go of his sister's jade hand, and the latter slowly fell into the sealed coffin, his face was a little pale compared to just now, but his breathing became much more stable.

"You don't need me to teach you the rest of the matter."

With that, Qin Yi flicked his fingers, and a wisp of Jiuyang Heavenly Fire, which was only the size of a soybean, fused with the Xuanyu Fire Yuan, looked a little dark red, and flew towards the Purple Rainbow City Lord.

"Thank you."

The Purple Rainbow City Lord's face was pale at the moment, and he obviously suppressed the Seven Veins Demon in his body with all his might, so he said with difficulty, and as soon as he stretched out his big hand, a purple-red flame emerged from his palm, which was his Dan Huo, which absorbed Qin Yi's Nine Yang Heavenly Fire at once.

He understood why Qin Yi wanted to let their brother and sister exchange blood, if his sister's cultivation realm was high enough, like the Yuan Shen Stage, in fact, even if she didn't exchange blood, she could detoxify, but his sister was only in the realm of the Qi Dao, and she couldn't use the Danhuo, so she couldn't drive out the body's Seven Veins Demon well.

When Qin Yi heard this, he just smiled faintly.

At least, things are going well.

So, he went aside.

The city lord of Zihong sat cross-legged on the spot, using his skills to burn poison.

……

"By the way, did you find anything?"

Qin Yi wanted to take a look at the sister of the Purple Rainbow City Lord, not only to see the poison, but also to let the little ghost dragon girl determine one thing.

"It's really artificial."

The little ghost dragon girl said with some solemnity.

"Artificial?"

Qin Yi knew that what the little ghost dragon girl was referring to was that there was a shadow of the demon clan behind the Seven Veins Demon.

I learned from the mouth of the little ghost dragon girl that although the demon race had not appeared in the Heavenly Saint Continent for a long time, in ancient times, the demon race could be said to be a frequent visitor to the Heavenly Saint Continent.

Therefore.

On the Heavenly Saint Continent, there are some demonic poisons, which may be left over from that era.

Even, in the individual tombs of the Heavenly Saint Continent, the people buried were the people of the demon race.

In order to prevent theft, there will be major demon poisons in these demon tombs.

The little ghost dragon girl told Qin Yi that there are two kinds of seven-vein demons, one is the ownerless seven-vein demon, and the other is the main seven-vein demon.

As the name suggests, once you fall into the ownerless seven-vein demon, the demon corpse you become will not obey any demon people.

And if you fall into the Lord Seven Veins Demon, the demon corpse you become is just like a puppet, but it is more powerful than an ordinary puppet, and it can also cultivate and grow.

Obviously, the Seven Veins Demon in the sister of the Purple Rainbow City Lord is the Lord Seven Veins Demon.

It stands to reason that there should not be a Lord Seven Veins Demon in the Heavenly Saint Continent, at least the little ghost dragon girl is very sure of this.

There is a master of the seven veins of the demon is the existence of the expiration date, generally only two or three years, once it expires, it will become the ownerless seven veins of the demon.

If the Seven Veins Demon was left over from ancient times, it was naturally impossible to have a master Seven Veins Demon.

"By the way, you'll ask how his sister was poisoned."

The little ghost dragon girl suddenly said with deep meaning.

"What do you want to do?"

I don't know why, Qin Yi's heart couldn't help but tremble, and he had a bad premonition.

"Hehe, it won't be a bad thing."

The little ghost dragon girl said jokingly, and stopped talking.
