Fang Tianyou knew the power of these toxins, and with his innate Dao base body, he didn't dare to ingest them casually, so soon after entering the valley, he switched to innate internal breath.

Now that he has reached the realm of foundation building, and the innate Dao foundation is small, Fang Tianyou can completely change to internal breath for several hours, and the true yuan will run the whole body to meet the needs of the body's cells.

"This is really the base of the Five Poisons Sect. The poisonous gas is even worse than my teacher has rumored. It's just the periphery, and I don't know how strong the toxin will be in the core. Chen Yifan sensed the surrounding environment in surprise, and his eyes showed a scorching light.

He was already cultivating poisonous skills, and he had to absorb poisonous gas frequently, so this little poisonous gas on the periphery was nothing to him at all, as long as he ran the exercises, he could even absorb these poisonous gases and use them for cultivation.

"This should be because the Poison Miasma Valley is closed all year round and does not circulate to the outside world, and the Poison Vine keeps releasing toxins, so the toxins in the valley are getting thicker and thicker. Fang Tianyou speculated, "Let's go inside a little bit more, and first help choose the best place to use these toxins to cultivate." ”

"Young Master, don't you want to take my Detoxification Pill?The poisonous gas here is still quite difficult to deal with?" Chen Yifan took out a bottle of Detoxification Pill and sent it to Fang Tianyou.

"I don't need to, don't worry. Fang Tianyou didn't take the antidote pill and continued to walk forward. Chen Yifan knew that it was impossible for Fang Tianyou to joke with his life, since he didn't want it, there must be a way, so he didn't ask anything more.

The group headed deeper into the valley. Although there was some thin smoke, the sun was still strong at this time, so you could still see the situation in the valley through the mist.

The further you go inside, the thicker the smoke becomes, and the toxins gradually increase. Fang Tianyou also found that a lot of poisons and poisonous insects appeared in the valley from time to time, not only that, but even a few medicinal herbs seen along the road also emitted poisonous gas from time to time.

"These poisonous insects and poisons seem to have been kept here like domestic animals, and these medicinal herbs should have been deliberately cultivated. Fang Tianyou said.

"That's right. The Poison Miasma Valley is a poisonous world. It is rumored that in the past, some people in the Five Poisons Sect were responsible for raising poisonous insects and cultivating poisons, and some disciples were responsible for collecting various venoms and toxins every day.

All these venoms and toxins must be handed over to the sect, and then the sect will distribute a part of it to the disciples according to their merits. Chen Yifan replied.

"I see. Fang Tianyou nodded.

"Young Master, the toxins here are already the limit of what I can bear, I think I can cultivate here. Chen Yifan sensed the toxins around him and said.

"Cultivating here, are you sure you can break through to the Grandmaster realm?" Fang Tianyou asked.

"This, I'm afraid it's difficult, if you keep cultivating here, maybe you can. The problem is that I can't stay here for long, and I can't digest the toxins for a while. Chen Yifan said awkwardly.

"Then we still have to find the poison vine. Fang Tianyou looked at the depths of the Poison Miasma Valley and said.

"But I didn't expect the toxins in the valley to become so strong after years of precipitation. It seems that going deeper into the valley to obtain the poison vine is far more difficult than I expected. Chen Yifan sighed.

"It's not hard to know if you try it. Fang Tianyou said with a firm gaze.

"Young Master, in fact, you don't need to get the poison vine, if you take me here a few more times, you may be able to break through to the Grandmaster Realm as soon as possible. I don't want the young master to venture into the depths. Chen Yifan heard what Fang Tianyou meant, and he still insisted on going deep into the valley, and he couldn't help but be a little worried.

"You take the poison vine not only to help you cultivate, but also to get the poison vine to use to refine medicine. So now that I'm in, I'm determined to get it. Fang Tianyou said.

"It is recorded in the books of the Five Poisons Sect that poison ivy does have the effect of entering medicine, fighting poison with poison, and can also refine a good medicine for detoxification. However, young master, can you really deal with the toxins here, this can't be careless. Chen Yifan was still a little worried.

"Rest assured, I won't do anything I'm not sure of. Hurry up and cultivate. I'll just go forward and probe alone, and if I can't bear it, I'll retreat. Fang Tianyou comforted.

When Chen Yifan heard this, he found a protruding rock, sprinkled his special detoxification and insect repellent powder around it, explained to Fang Tianyou, and began to cultivate.

Fang Tianyou saw that Chen Yifan was gradually entering a state of cultivation, so he slowly walked forward. He walked very carefully, because from time to time he had to deal with poisonous insects and poisons that came out of nowhere.

Although he can use the true yuan to expel toxins, but now that he is in a world of toxins, he does not have time to detoxify calmly, so if he is bitten, it is still a very troublesome thing.

Alone in the direction of the valley, Fang Tianyou speculated that he should have reached the depths of the valley. There are basically no poisonous insects or other poisons here.

The yellow haze, which was still as light as a thin veil on the periphery, was already as thick as a smoke screen here, and even the sunlight could not penetrate it. Fortunately, Fang Tianyou had divine sense and Yin Ghost assistance, so he could still explore the surrounding terrain.

Of course, Fang Tianyou didn't dare to be careless. Chen Yifan had never been here at all, and no one had come in for years, so no one knew what kind of potential danger there would be.

After carefully walking out for a hundred meters, some long brownish gray vines the size of chopsticks sparsely appeared on the ground in front of him, the color looked like they had died, but Fang Tianyou detected that these long rattans were still alive.

"Sure enough, it's a poisonous demon vine, it seems that it is not far from the magical poisonous demon vine that Chen Yifan said. "Fang Tianyou had also seen the Poison Demon Vine in the Immortal Cultivation Realm, so he recognized it at once.

It's a pity that these poison vines are still too small to be of use at all, so Fang Tianyou had no choice but to continue to rush forward. The further you go in, the thicker the poison ivy becomes, from the size of chopsticks, to the size of your thumb, to the thickness of a table tennis racket, and after not going far, there is the thickness of an ordinary person's arm.

"Whew!" Fang Tianyou was walking, when he suddenly felt the sound of breaking the air behind him, and a brownish-black phantom was like a whip, rolling towards Fang Tianyou.

Fang Tianyou kicked with both feet, and used the "Ascending Step" to avoid it, but his face changed slightly, because under the detection of his divine sense, he found that the attack on him was actually a poisonous demon rattan. Poison Rattan actually took the initiative to sneak attack people, which shows that Poison Rattan has already had an autonomous consciousness.

The year of the poison ivy with its own meaning is definitely not low, and if it can be used as medicine, it should not be worse than the elixir. However, it is precisely because such a poisonous demon vine is old and refined, it is also a little troublesome to deal with, at least for Fang Tianyou, who is in the foundation building realm, there is a lot of trouble.

Sure enough, Fang Tianyou had just avoided the poisonous demon rattan, and there were two more sounds of breaking the air in his back, not only that, but the rattan that had been empty before slapped on the ground and rolled up again.

This time, it was three poisonous rattans, drawn towards Fang Tianyou from three directions. Fang Tianyou couldn't avoid it, so he had to kick his feet, raise his body high, jump into the air, and once again avoid the encirclement of the rattan.

However, Fang Tianyou's movements were fast, and the reaction of those rattans was not slow, and after the whipping failed, he immediately changed direction like a spirit snake and rolled towards Fang Tianyou again. And this time, two more poison vines joined, and a total of five poison vines attacked Fang Tianyou together.

Fang Tianyou knew that he couldn't hide anymore, so he controlled the cold iron needle to pierce those rattans. "Boom, boom", the cold iron needle instantly pierced through the two vines in front of him.

After the vine was pierced, it shrank back as if the tentacles of an animal were pricked and painful, and the encirclement formed by the other party's Tianyou leaked a flaw.

Fang Tianyou was about to break through from this flaw, but the two vines that had been pierced spewed out two streams of dark green liquid from the wound and sprayed straight towards Fang Tianyou's face.

The smell of fishy poison came to his face, Fang Tianyou knew that this liquid contained strange poison, and he didn't dare to be sprayed by the venom, his feet kicked in the air, and his body turned backwards. The venom landed on the ground, making a "sizzling" sound that emitted an unpleasant, pungent smell.

Fang Tianyou said in his heart that these juices were indeed highly poisonous, but it was too late for him, and the other three vines had already been pumped around. Fang Tianyou was bold and dodged one of them.

At the same time, he opened his bow on the left and right with both hands, and struck a "dragon catcher" at the two that came at the head, only to find that the two vines were not only unusually tough, but also extremely silky.

Fang Tianyou originally thought that with his "dragon catcher", not to mention breaking the vines, at least he could push the vines away, but when he hit it, he was as powerless as hitting a sponge, and he felt that as soon as the vines were soft, Fang Tianyou's strength was removed.

Not only that, but the entire vine also wrapped around Fang Tianyou's hands. If it is really entangled, with the tenacity of these vines, I am afraid that it will be difficult to get out.

Fang Tianyou didn't dare to be careless, and as soon as his mind moved, a fireball talisman appeared in his right hand, and then a hot fireball appeared out of thin air, burning towards the two vines that wrapped around Fang Tianyou's wrist.

As soon as the fireball came out, the vines retracted in fear, but finally they were still stained by the sudden flames, and then the vines began to burn, and the vines let out a slight whimper as if they had been injured.

Fang Tianyou repelled the vines, so that he was able to land safely on the ground. Seeing that the vines were really afraid of fire, I secretly breathed a sigh of relief in my heart. Otherwise, these vines come and go, they are hidden, resilient, and poisonous, and it is really not easy to deal with them.

As soon as he breathed a sigh of relief, the two vines that had been burned suddenly broke off from the fire. Fang Tianyou originally hoped that the flame would burn down the vine to the main trunk of the vine.

Who knew that in order to protect itself, the vine actually broke off from the wound like a gecko's broken tail, leaving the already burning vine to continue burning on the ground, and the rest of the part quickly retracted and disappeared in a blink of an eye.

However, the other vines were not frightened by Fang Tianyou's methods, but instead seemed to be aroused by ferocity, and several more vines were drawn towards Fang Tianyou's side like whip shadows.
