That silver ray seemed to be extremely flexible, and after spewing out a mouthful of poisonous mist, it immediately drilled into the ground.

"Bang!"

It's a pity that this is Lu Kun's cave mansion, which is shrouded in prohibition, and Yinmang directly hit the prohibition.

However, the silver mang didn't seem to give up, it quickly turned into a silver needle state, and at the same time, the silver mangs on its body were even more dazzling, and continued to thrust towards the ground that flashed with forbidden light.

"Dang!"

An extremely crisp voice flashed, and on the ground that was originally empty, a fist-sized purple-black thunderball suddenly appeared, just blocking the silver needle.

Yinmang seemed to be a little stunned by this thunderball, and at this time, another thunderball flew from behind, forming a pinching momentum with the previous thunderball, trying to sandwich it in the middle.

Yinmang was in a hurry, let out a panicked chirp, and shot to the side.

With the sound of a thunderstorm, a burly figure appeared in front of the silver mang in an instant.

A fist large enough to look up at it hit its tiny head, and strangely it didn't contain much power, just a thrust that pushed it backwards.

The two thunderballs behind him had become the size of a watermelon, and the concave side of the two was aimed at this silver ray, and they closed in the middle, and immediately trapped it in it.

"Strange, I heard that after the death of the master, the Gu worm will be greatly injured, and then it will fall asleep, but this little guy is unharmed, it seems that it is more difficult than ordinary spirit worms. ”

Lu Kun, whose face was slightly darkened, said in surprise.

"After the poisonous mist just now was inhaled into my body, it went straight to the internal organs, if it weren't for the fact that over the years, I had made a lot of progress in the calcining period, and the mana of the internal organs was quite abundant, and it was really possible to be escaped by it. ”

Listening to the sound of collision coming from the two thunderbolt balls the size of watermelons, Lu Kun muttered: "Looking at the situation of this little thing burrowing into the ground, I'm afraid it has a little penetration ability." ”

"The thunderball made of silver dragon meteorite is trapped, and it should be foolproof. ”

It turned out that as soon as the spirit beast bag was opened, it just woke up the sleeping silver silkworm Gu, and immediately wanted to escape from here, but it didn't expect that the poisonous mist it spewed out had no effect at all.

After the poisonous gas entered Lu Kun's internal organs, before he could corrode these organs, he was wrapped in the thick thunder attribute mana in the internal organs.

During the period when Lu Kun was catching the silver silkworm Gu, he also saw the silver mang clearly, it was a silver silkworm, much fatter than ordinary silkworms, and there were pink and delicate feet all over the bottom.

In the earliest form, the two big eyes of the Silver Silkworm Gu occupied half of the head, and the poisonous mist erupted from the small mouth under its eyes, and later after it became the form of a silver needle, the eyes were small and difficult to catch, and the mouth disappeared.

Lu Kun put aside the combined thunderball containing the silver silkworm Gu, and also lost that there were inlaid concave and convex grooves on both sides of the thunder ball, and the two grooves were buckled together, which happened to be a small enclosed space, just closing this silver silkworm Gu worm.

Then he used the mana in his internal organs, and at the same time, a jade bottle appeared in his hand, and a lump of black liquid accurately entered the jade bottle.

"I'm still thinking about how to force out the poison from this Silver Silkworm Gu, but I didn't expect it to have spirituality, launch a poisonous mist attack, and let me successfully obtain this Silver Silkworm Gu Poison. ”

"But this silver silkworm Gu is a little strange, let's take a look at the jade slip in Qingtian first. ”

Lu Kun muttered to himself, and then opened the jade slip that explained the Silver Silkworm Gu Technique.

Cultivators outside the Gu Poison Sect want to cultivate the Gu Technique, it can be said that it is even more difficult, without the basic exercises of the Gu Poison Sect, even the simplest Gu cannot be refined by outsiders.

However, Lu Kun and the others caught this Silver Silkworm Gu for the poison in their bodies, and they didn't think about refining it at all.

Only an hour later, Lu Kun finished reading this jade brief, and he muttered, "According to what was said above, this Silver Silkworm Gu needs to go through three sacrifices before it can be used completely. ”

Xiao Yun said, this Silver Silkworm Gu was immediately captured by them after the first sacrifice, and in such a short period of time, it is very likely that the spirituality of the original ten thousand poisonous insects has not completely disappeared. ”

So when it woke up, it resisted as soon as it could, trying to escape. ”

"The Gu Poison Sect's Gu techniques are all to strengthen these heaven and earth spirit insects, although these ten thousand poisonous insects have only gone through the first sacrifice, they are also much stronger than before. ”

"What Xiao Yun and Xiao Yanzi are at least the poison sprayed by the Silver Silkworm Gu that has been sacrificed twice. ”

Lu Kun frowned: "That is to say, the Silver Silkworm Gu Poison I have collected now is at least weaker than any of them. ”

"Silver Silkworm Gu Poison is finally trying, let's take a look at the other poisons they have collected first. ”

Lu Kun put aside the jade slip and the jade bottle containing the silver silkworm Gu poison, ready to test the poison.

You must know that the poison refined by immortal cultivators is completely different from that refined by mortals, and the poison materials in it are all of the same grade as the elixir.

If it was an ordinary mortal poison, even if it was an ordinary immortal cultivator with an average physique, it would not have any effect.

Lu Kun first tried the corrosive poison that Huang Xiaoyun and the others were, in order to test the effect of the poison, Lu Kun first dropped some on the skin, because when Xiaoyun was poisoned, it was injected into the skin.

When this drop of poison, which was extremely black and had a strong rancid aura, dripped on Lu Kun's arm, the venom first made a gurgling sound, and then Lu Kun felt the power of an intermediate primary-level spell acting on his skin.

Obviously, this kind of power could not break through Lu Kun's defenses, and after this drop of poison was ineffective, it spread out, turning into a fine dense mist, trying to penetrate into it.

Lu Kun just wanted to test the strength of this poison, so he simply let go of the tense muscles, constricted the mana of his body and did not resist, and let these poisonous mist-like poisons enter his arm.

After the corrosive poison entered his arm, it spread rapidly to all sides as if he was like a fish in water, and the corrosive power carried by the poison spread all over Lu Kun's entire right hand in an instant, making his arm black.

Next, this poison wanted to penetrate into Lu Kun's blood, but unfortunately, even if Lu Kun converged his blood mana, this poison with corrosive power was also dissipated by his vigorous qi and blood power, and it could not enter the blood vessels.

And this little bit of venom can only cover one of Lu Kun's arms.

"This poison is trying to corrode my muscles, and with my current muscle strength, even if I don't use mana, it won't be able to do any damage to it. ”

"If the amount of poison is too small, it will gradually deplete the poison and disappear in my body, if there is no way to corrode the muscles, there will be no way to assist in refining the body and quenching the body. ”

"According to the strength just now, this corrosive power can cause certain damage to the physical cultivation of the muscle refining stage and the bone quenching stage, that is, it can have a promoting effect on their body quenching. ”

"However, after entering the coagulation period, the power of qi and blood has increased greatly, and the muscles have been strengthened to a very strong level, and this level of toxicity cannot be helped. ”

Next, he tried the effect of corrosive poison a few more times, and after a little contemplation, he recorded it on a new jade slip:

Corrosive poison, it has a not weak quenching effect.

It has a strong auxiliary for the muscle refining period, but it is very dangerous to use during the muscle refining period, and it is likely to let the toxicity enter the blood, causing internal organs to corrode and die.

For the bone quenching stage, the effect is average, and the danger is low.

It has no effect on physical cultivation above the coagulation stage.
