In this way, while refining his own poison meridian heart method, he let the two connecting branches absorb the venom in the cave.

This kind of cultivation lasted for three whole days.

In the past three days, the purity of Lin Yan's poison scripture has reached a terrifying level.

The cultivation of these three days is like making a sword, although Lin Yan has broken through before, it is still a piece of iron containing a lot of impurities, although it is hard, it can't be used very well.

And these three days of purification are repeatedly beating this hard piece of iron in the blazing fire.

Iron is formed from minerals and excavated, which takes a long time, but the process of purification, three days is enough.

After three days of cultivation, this piece of iron has become an extremely sharp iron bar, and there are no impurities in it, although the volume has been reduced, the mass has not changed, resulting in a very high density, and it has become harder and sharper.

If Lin Yan's cultivation of the Poison Sutra is compared to making a sword, then he only needs one last step now, putting the sharp iron bar into the blank of the sword and cooling it, so that a sharp sword has already been preliminarily made!

Lin Yan is just one last chance to complete his transformation!

When I first saw this cave, I felt that there were too many poisonous insects in it, and it was dense because the space of the cave was limited, and the three days of cultivation had made the entire cave a little empty.

In addition to Lin Yan's cultivation, he also discovered several interesting things.

These miniature ancient poisonous insects didn't seem to be aggressive, and when they injected the poison into Lin Yan's body, they all seemed to have become much more sluggish.

At this time, some ordinary poisonous insects of the same kind will come over and inject their own poison into their bodies, which will give them vitality.

It's like ...... These ancient poisonous insects were bred for something!

After absorbing a large amount of venom, his two branches turned black, and they could no longer see their original color, but turned into two black shiny branches.

The current Lian Li branch is amazingly heavy, and if Lin Yan didn't run the Poison Sutra Heart Method, he wouldn't be able to hold these two branches at all, and the cold went deep into the bone marrow!

The most surprising thing he found was that after he had caught most of the dense ancient poisonous insects in the cave, he found that there was another poison inside, which he had never seen in eight months!

It looks like a cow, but it's much smaller than a cow. The ordinary poisonous insects in the five poisonous dwellings are much larger than the outside, and in addition to the bright colors, the body size in the cave is not even as large as the wild five poisonous insects outside, and this kind of poison that looks like a cow is smaller than the ancient poisonous insects in the cave!

The head is white, with the tail of a snake and only one eye!

When Lin Yan was young, Lin Aotian was responsible for teaching him to read, in addition to the five elements gossip of Qimen Dunjia recorded in the Book of Changes, Lin Aotian taught him the most, which was the "Classic of Mountains and Seas" and some art of war.

He had a little impression of this poison, and carefully searched the memories in his mind, remembering that in the "Classic of Mountains and Seas", there was a kind of fierce beast recorded, which seemed to be like this!

Cockroach!

Legend has it that the king of all poisons withered when it entered the grass, and when it entered the water, the water dried up immediately. It carries a lot of diseases and is the source of the plague!

It is said that when the Poison Sutra is cultivated to the Great Perfection, it is also a plague that can be turned into a piece at will! This striking similarity does not know whether it is accidental or inevitable.

However, Lin Yan found that there was more than one in the cave, and there seemed to be several. However, these legends have lost the power recorded in the "Classic of Mountains and Seas" in ancient times, but the appearance is very similar, but the body size is extremely petite.

If it weren't for Lin Yan's powerful eyes, he wouldn't be able to see clearly.

Lin Yan really wanted to try the toxicity of this king of ten thousand poisons, but firstly, because a few dragons were not interested in Lian Lizhi at all, and they seemed to disdain to rob with these poisonous insects around them, so they couldn't catch them at all.

It doesn't matter if he fails and dies here, there will be no one to avenge his family's blood vendetta!

Therefore, Lin Yan planned to take advantage of the fact that there was no one during this time to get as many benefits as possible in this cave.

Although he didn't dare to try the few dragons lurking in the cave easily, there were still many miniature ancient five poisons.

He knew very well that Dabi was coming to an end, and there was not much time left for him to cultivate to his heart's content, and he didn't dare to waste the slightest, so he devoted himself to the process of cultivating with ancient poisonous insects.

This time, when he had just run the Poison Sutra Mind Method for two weeks, and all the poisons of the seven-inch Yin Snake, the Hundred Section Centipede, the Millennium Cold Snake, and the Red Fire Poisonous Scorpion in his body were removed, the mutation protruded!

The worm in the cave seemed to feel that the poisonous insects around it had recently reported back to them a lot less virulence, and let out bursts of piercing screams!

After the scream, as if there was a chain reaction, Lin Yan'er heard a loud sound above his head, as if the top of his head was about to collapse!

Lin Yan didn't dare to be careless, he didn't know what the situation was, and concentrated his energy to deal with the upcoming mutation.

Boom Boom Boom......

The rocks above the head collapsed, and it turned out that there was a hole in it!

The position where Lin Yan stood was the core of this formation, when he thought that the turbidity qi had descended and he found the cave below, he didn't expect that there was a cave above!

The toxicity of this formation condensation had indeed decreased, and Lin Yan could clearly feel that there was almost no poisonous gas in the cave above.

The rest of the Five Poisons Center, both above and below, were covered with poisonous gas, and only at the core of the entire Great Array would the poisonous gas of the entire Five Poison Houses be condensed and descended into the underground cave to supply the nourishment of these mini ancient beasts.

As the cave above collapsed, an extremely strange-looking bird flew out of it!

At first glance, it looks like a pheasant, and after flying out, it chirps into the burrow.

And the legendary king of all poisons, the source of the plague, when he saw this pheasant-like bird, he was extremely panicked, twisted his snake tail, and hid in the place where the poisonous insects were most.

Seeing this, Lin Yan was taken aback, this seems to be another kind of fierce beast recorded in the "Classic of Mountains and Seas", the plover!

The cycle of heaven, one thing descends to one thing, the bird is the nemesis of the dragon, in ancient times, it was specially fed on the dragon!

The bird wandered in the air a few times, staring at the cave all the time, while Lin Yan, who was standing next to him, was completely ignored by it.

Extremely rare mountain and sea scripture beasts, Lin Yan actually saw two in just a few days! The original Tang Sect ancestor, how much magic power did he have, he could actually find these two fierce beasts!

Although it's just a miniature type with some blood.

Moreover, what puzzled Lin Yan the most was that what was his purpose in raising these two fierce beasts?!
