The silver needles in the formation turned into clouds in the sky and pressed directly on the top of Kang Yi's head, but Kang Yi's face remained unchanged, and after the seal, his hands were lifted upward, and a black qi immediately came into being.

This gas is the poisonous gas converted by Kang Yi with the help of the auxiliary exercises, after a fight, Kang Yi found that as soon as the silver needle was contaminated with the attached poisonous gas, it disappeared directly, it can be said that Kang Yi's poisonous gas just restrained this silver needle, so this time Kang Yi converted all the mana in his body into poisonous gas.

For a while, the poisonous gas on Kangyi's hands became more and more vigorous, and it was several acres in size, covering Kangyi.

And Kang Yi didn't have the idea of sitting still, he roared softly, and all the poisonous gases the size of several acres came out, turning into arm-sized gases, scurrying around at will, stirring up this formation to sway wildly.

The head of the Yu family outside, seeing this sudden change in complexion, did not delay any longer, pressed down with his hands, and the white feather immediately turned into endless 'rain silk' and fell, Kang Yi saw this and shook his hands, and those chaotic poisonous gases immediately retracted, turning into a huge black vortex above Kang Yi's head.

The black qi emanating from the center of the whirlpool was even stronger, and a monk who cultivated a little lower, if he inhaled this poisonous gas, he would be poisoned and killed immediately.

Those falling silver needles did not react when they fell into this whirlpool, and the head of the Yu family shouted when he saw this, and was about to withdraw his hand and retreat, but he heard Kang Yi cry urgently.

"Open!"

As soon as this sound fell, the black vortex immediately amplified, stirring up the formation to swing wildly, and then only one sound.

"Boom"

This formation was immediately shattered by this black whirlpool, and the violent mana was vented everywhere, and the Yu family couple who were closest to this were the first to bear the brunt, and were directly swept up to the sky by these mana, and then smashed down heavily.

In fact, there is no distinction between these two scriptures, both of which have their own advantages, but in terms of fighting alone, this "Salvation Sutra" is indeed inferior to the "Extinction Sutra", Kang Yi can fight with one enemy and two (those two foundation juniors, basically not count), it is by virtue of this, of course, it is directly related to the purity of Kang Yi's own mana.

After this fight, Kang Yi barely won a small victory, and it can also be said that the two sides barely fought a tie, because Kang Yi just cast that huge whirlpool, and the mana consumed was really not shallow, and now there is no strength to fight, and the people of the Yu family are almost the same, all of them are limp on the ground, just like the two foundation juniors, and they passed out directly.

Kang Yi was afraid that the Yu family would have reinforcements here, so he didn't dare to stay longer, so he staggered up at will, ready to leave.

The couple of the Yu family were also injured a lot at this time, but they still stood up for the sake of the "Extinction Sutra" and said in a deep voice.

"Fellow Daoist, if you don't hand over the "Extinction Sutra", don't think about leaving!"

After the head of the feather family finished speaking, although he spit blood, he opened his sleeves and released a fourth-order demon beast tarsal bone rat, and now the head of the feather family did not immediately let the tarsal bone rat rush over, it is estimated that it is taboo Kang Yi has any other means, if this tarsal rat is also dead, then the two of them are really lambs to be slaughtered.

Seeing this, Kang Yi asked coldly, "Why do you still want to fight?"

After saying this, Kang Yi revealed the sleeve of the storage dragon, how powerful is the breath of this dragon, even if it is only a third-order demon beast now, but as soon as the breath is released, it makes the tarsal mouse tremble, Kang Yi did not directly summon the dragon, just want to fake the tiger, if it is summoned, it will be exposed.

The two members of the Yu family were even more shocked when they saw that their tarsal rat was so frightened that they didn't dare to say anything more, so they had to watch Kang Yi leave, but Kang Yi had just taken two steps, but the Yu Bai clan said.

"Fellow Daoists, we can exchange the "Salvation Sutra" with you for the "Extinction Sutra"

It is estimated that the Yu family really didn't want this "Salvation Sutra" to be taken away by Kang Yi like this, and immediately made such a proposal.

"How?"

Kang Yi was at least ten zhang away from the two of them, and then he turned around and said.

In response to Kang Yi's question, the two of them lowered their heads and discussed two or three breaths, and Kang Yi mistakenly thought that these two were delaying time and waiting for rescue, so he hurriedly said.

"Don't delay the two of you, decide quickly"

In fact, Kang Yi misunderstood others, this Yu family is now the only one who can move to the stage, and the others are all swaddling babies, overwhelmed by the heavy responsibility, how can there be any reinforcements.

"We are willing to exchange the first half of the Sutra of Salvation for the second half of the Sutra of Destruction," the two men said, standing behind the tarsal rat.

Originally, these two wanted to exchange the entire "Salvation Sutra" for the entire "Extinction Sutra", but after thinking about it, their own cultivation methods were all obtained by the other party, and their own family would not be in danger in the future, so they retreated to the next best thing, and said so.

"Daoist friends are really good plans, we all know that the first half of these two scriptures is some poison and saving people, it is estimated that there is a little auxiliary exercise, and the second half is the root of cultivation, don't you think that the two Taoist friends are too disadvantaged in this way?"

There really is no eternal enemy in the world, only eternal interests, and only a few people are still enemies of life and death, but this meeting has become a trading partner, which is really difficult to say.

In fact, for Kang Yi, he already has a nameless exercise as the foundation of his practice, and the second half of the two scriptures are useless to Kang Yi, and now he uses the second half of the "Extinction Sutra" to change the upper part of the "Salvation Sutra" of the family, which is still a big bargain for Kang Yi, but in order to maximize his own interests, he still has to discuss.

"How about we add another 500,000 spirit stones as compensation," the head of the Yu family thought for a while, and said again.

"A million!" Kang Yi didn't think about it, and said directly.

"Okay, deal" The head of the Yu family agreed very happily, and first threw over a sleeve to show his sincerity, Kang Yi picked it up and took a look, it was indeed a million spirit stones, looking at the head of the Yu family, he was so bold in his shot, and he knew that he wanted a little more.

In fact, although this Yu family rarely walks outside, there are many people who come to seek medical treatment, this door-to-door one, the Yu family has to pull out a layer of skin, so this Yu family is very rich, and a million spirit stones are actually nothing.

Then the two sides printed the part demanded by the other party in the jade slip and sent it over, and the transaction was completely completed.

After this incident, Kang Yi had no intention of staying, and left directly, and although the two of the Yu family were unwilling, they had to do this.

Kang Yi smoothly left the Yu family's sphere of influence and headed down the mountain of Jade Dragon Mountain.
