After Han Fei casually slammed the Dao technique, soon several frog demons rushed over, and looked at Su Mengli who had already woken up with wary eyes. He had to explain a little to a few frog demons, and the frog demons relaxed a little after listening to them, and then a few frog demons began to croak

Communicating, the last leader nodded towards Han Fei, although they were reluctant, although it was double the spirit stone, but the poison was of great help to their enlightenment, and even the leading one was ready to be used to impact the Jindan period in the future, but Han Fei was here, and he had to endure the pain and cut his love, but anyway, there were still two immature ones, and there would still be a chance in the future.

"Miss Su, they agreed, let's go, let's go see the so-called poison" Han Fei said to Su Mengli with a smile on his face.

"Gongzi Xie Han, if you don't dislike it, just call me Mengli!" Su Mengli also has a good impression of this young man, he can practice in this Heavenly Wolf Mountain Range at a young age, and his realm is not bad, compared to the talent of the sect's candidate saintess, only because of the grade smiled, the realm is slightly inferior.

"Then you can just call me Han Fei, I'm really not used to calling Childe. Han Fei replied briskly, this world is much more complicated because of its strength, which is what he is most uncomfortable with.

After the two of them said that, they walked towards the center of the swamp, Su Mengli was very weak and walked very slowly, but men and women did not kiss, and they did not let Han Fei help, Han Fei didn't think about it so much, seeing that Su Mengli was having difficulty walking, he directly hugged her and flew up, and Su Mengli's delicate body trembled, but she did not refuse, the current situation did not allow her to refuse, this swamp is really not easy to walk on the ground.

The frog demon led the way in front, Han Fei and the two followed, and after a while, they came to a small waterhole, the fog here was particularly thick, and the fog was also full of poisonous gas, forming a poisonous barrier, Han Fei had to release the Dao momentum to resist the erosion of this poisonous barrier, but the frog demon and Su Mengli didn't feel it at all.

Su Mengli saw a few aquatic grass-like plants in the waterhole through the poison barrier, and was surprised, "It turned out to be the arrow poison heart-wrapping grass, and the other one is five hundred years old, which is no less than a treasure spiritual object!"

"This looks like an ordinary aquatic plant, it is similar to a rare spiritual object!" Han Fei was also surprised, this waterhole looked a little greener, it was similar to an ordinary waterhole, and the so-called poison turned out to be a few aquatic plants inside, but Han Fei didn't know it.

This made Han Fei a little frustrated again, his knowledge was really poor, after returning to the sect, he must find some books about the strange things of heaven and earth to make up for it, otherwise he won't know the good things he encountered in the future, his previous use of spiritual objects was to eat them directly, in fact, he wasted a lot of spiritual power, and if he encountered poisons, it was estimated that he would only have to watch.

"Well, this is the Essence of the Arrow Poison Twister, the ordinary Poison Twister is just a mortal poison, and if it is five hundred years, it is already a treasure, if it is tens of thousands of years, it can even absorb the essence of heaven and earth to produce spiritual wisdom, it is also a special demon beast, and its grade is naturally a fine product."

Plants are the most difficult to become demon cultivators, because it not only takes a long time for them to give birth to spiritual wisdom, but they are also easy to be picked during this time, and even after becoming demon cultivators, it is easy to cause other demon beasts of cultivators to chase and kill, in front of spiritual objects and poisons.

Han Fei didn't know this, but this time he was just surprised in his heart, he didn't know that plants could also become demon cultivators.

"Will these plants heal your injuries?"

"Yes, the five-hundred-year-old one will do, and the others will not be cost-effective if they are picked in advance, the frog demons also need it, I believe they just agree to the five-hundred-year-old one, and they will not exchange the remaining two. ”

Su Mengli was in a very good mood at the moment, she couldn't imagine that in a small basin here, there was really a five-hundred-year-old curare poison heartworm, if she took it directly, although it would greatly waste a lot of poison, it would also be able to heal her injuries.

"Well, I don't know the value of these things, so you might as well just offer them. Han Fei pointed at the frog demon.

"The poison of the treasure is already very rare, I am willing to exchange five hundred medium-grade spirit stones!" Su Mengli was the saintess of the Absolute Heart Poison Sect before, and there was still no shortage of spirit stones, she had thousands of medium-grade spirit stones in her bag at the moment, and hundreds of high-grade spirit stones.

"Five hundred medium-grade spirit stones! so expensive!" Han Fei swallowed his saliva, all the spirit stones on his body combined, it was only five hundred medium-grade spirit stones, which was still the reward of the competition, and he now knew how poor he was compared to the rich.

"According to the price of the auction house, it is not so expensive, just more than two hundred, but I said before that it will be doubled. Su Mengli explained slightly, and at the same time glanced at Han Fei strangely, no matter how this young man looked, he should also be a disciple of the Great Sect, how could he be so surprised by the five hundred mid-grade spirit stones. She just doesn't know the real details of Han Fei, although Han Fei has good talents, but he is worshipping the Green Bull Sect, the masters of the Green Cow Sect are quite many in the Southeast Region, but the resource background is not even as good as some small sects, which is also the reason why many young people are reluctant to worship the Green Bull Sect now.

Han Fei looked at the frog demon again, the frog demon was a thousand-year-old monster, and he still knew the value of this very well, so he nodded at him.

Su Mengli immediately took out five hundred medium-grade spirit stones from the Qiankun bag and handed them to the frog demon in the lead, seeing that Han Fei smacked his tongue, it was really five hundred medium-grade spirit stones, and then asked Han Fei to take her to the center of the waterhole.

She couldn't perform any Dao techniques now, so she directly grabbed the arrow poison heart grass, uprooted it, and then let Han Fei return to the edge of the pool.

Su Mengli was about to clean and swallow, Han Fei wanted to help, but was blocked by Su Mengli.

"Han Fei, this is a treasure-grade poison, even if a cultivator in the Jindan stage is not enlightened by the way of poison, he can't directly touch it with his hands, if he touches it, he will be poisoned in his body, and only the cultivators of our poison path can touch it. Moreover, this waterhole is not an ordinary waterhole, it should have been a long time ago that poisonous substances lived in it, and this place has long been turned into a pool of poison. Su Mengli once again explained to Han Fei, who didn't know anything about common sense.

"It's so poisonous, it can't be touched during the Jindan period, it really deserves to be a precious poison, and this waterhole is actually made of venom" Han Fei sighed for a while, he thought of the waterhole on the ape's side, which contained a trace of spiritual energy, and it was constantly dissipating in the air, there were definitely good things in it, maybe it was a rare spiritual object.

After Su Mengli washed the arrow poison heartworm, she formed a ball with her hands, first asked Han Fei to retreat a little, and then directly put it in her mouth and chewed it, and her body also sat cross-legged on the ground and began to refine.

Han Fei saw that Su Mengli had already started refining poisons, so he ordered a few frog demons to stay away, but he himself became a little interested in this poisonous pool, to be precise, he was interested in the way of poison, he wanted to see if he could use the poison here to comprehend a little poison.

He cautiously tried to touch the poison pool with his hand, and as soon as his fingers touched the liquid, there was a sizzling sound, and sure enough, it contained a highly poisonous substance, and almost broke through the barrier that Han Fei's Dao momentum had turned into.

Thinking that he would not be able to comprehend it if he didn't feel it personally, he simply put away the Dao momentum, and as soon as he put it away, there was a sharp pain in his fingers, as if his fingers had reached into the oil pot, and the pain in his heart almost couldn't help screaming, but when he saw Su Mengli, who was still concentrating on refining, he finally held back.

And I also paid attention to that finger, and slowly experienced the feeling of venom corrosion, and this experience really made some discoveries.
