Xiao Zheng threw the internal force ball to successfully clean up the Yin insects at the entrance of the hole, but there was a strong doubt about whether the sixth-layer could continue to go down, after all, even if so many Yin Insects were temporarily interrupted due to harassment, it was inevitable that they would gather again after a while, and the master thought about it again and again, and decided to give up for the time being today and continue tomorrow.

The students didn't have too many objections to this, and the first exploration was over, but although Xiao Zheng's team, which was dominated by grandmaster-level masters, did not make much progress in exploration, the harvest was actually quite rich, but the other eight teams made a lot of discoveries on the first and second floors.

It was still the passage that Yin Polang led the students to find before that came to the end of the abyss, but just by visually inspecting the abyss, the master judged that this abyss had definitely reached the depth of the yin cave in the academy!

Yin Polang had reported the news before, but the master didn't notice the problem at the time, but now he found out that more than a dozen masters should withdraw from the yin cave first and start to determine the new plan, and the students returned to start resting.

Compared with Xiao Zheng and other grandmaster-level masters, those students who entered the first and second layers of the Yin Cave seemed to be much richer, some were not in good spirits, and some were full of energy and kept saying something, the poor spirit was naturally because there was nothing worth exploring on the first and second floors, the reason why the masters were so cautious was to do it for the sake of safety, in fact, according to the strength of the students, where do they need two masters to take them to the first and second floors, of course, when they see something that other students can't see, their spirits will naturally get better.

After returning that night, he told Xiao Zheng about the situation of the day, due to the sudden increase in the number of students, the exploration of the snow mountain also increased, and many traces of fierce beasts were found during the period, but most of these fierce beasts were cunning and not so easy to catch.

Xiao Zheng also understood it a little, now that the burial snow fruit has been obtained, there are not many things on the snow mountain that can arouse Xiao Zheng's interest, but he is more interested in fierce beasts, but it is a pity that there is no grandmaster master in the student team now, and the possibility of encountering fierce beasts that are useful to Xiao Zheng is too low, and even if he encounters it, there is no possibility of hunting

Early the next morning, the students set out again, and Xiao Zheng and the others also followed the master to continue to explore, but today's master who traveled with him became four, and the master who entered the yin cave also became one per team.

There is not much to say about the arrangement of the academy, Xiao Zheng's team is much faster today because of yesterday's experience, but due to the characteristics of the yin cave itself, the students are not able to judge the direction according to their experience and feelings, fortunately, yesterday the master left marks on the cave wall along the road in advance, but many of these marks have become blurry or even impossible after one night

In addition to the fact that the time wasted on this was a little longer, the number of Yin Snakes suddenly increased for some reason after entering the fourth floor, especially at the entrance to the fifth floor from the fourth floor, which was another place for the team to delay time.

The Yin Snake is actually very difficult to entangle, the fierce Yin Cold Qi and the poisonous mist are mixed with a real headache for the students and even the master, plus the poisonous mist of the Yin Snake is not so easy to disperse, and when it enters the fifth layer, the fourth layer is basically surrounded by poisonous mist, if someone who does not know it breaks in, I am afraid that he will be poisoned immediately

The fifth-layer Yin Snake also appears very frequently, but compared to the fourth-layer, it is much less, and after this night, the Extreme Yin Grass seems to have increased, of course, the more are only the seedlings that have just sprouted.

"This is the entrance to the fifth and sixth floors, and I don't know if the Yin insects have decreased today!" The three masters watched from afar, although the entrance of the cave was indeed gone, but no one knew what it would look like further down.

"I'll go down and take a look first, you guys are waiting here!" The new master nodded at the students and the other two, and then headed for the entrance of the cave

The ability of the demon clan has something to do with the fact that it did not become a demon clan, so the ability of each demon master is different, so since this master was arranged, it is obviously that he has a certain restraint on the cold qi of this yin cave or the poison of the yin insect itself, so he dares to take risks, and the master will never do dangerous things, at least this is what the students think in their hearts

When this master approached the entrance of the fifth floor and entered the sixth floor, his body began to be surrounded by an inexplicable air current, which was obviously the master's way of resisting.

The master didn't go down for a long time, and then he conveyed the news of safety, and there was no threat from Yin insects on the sixth floor?

After the students went down, they found that things were a little different from what they imagined, the entire sixth floor seemed to be a corpse accumulation field of Yin insects, densely packed with the corpses of Yin insects, these corpses were basically intact, that is to say, these Yin insects did not cause their death for any other reason.

The students stepped on it, and the effect of the internal force on the corpse of the Yin Worm was still there, and the footprints were extremely clear, just higher than the surface of the foot, which showed how many Yin Worms there were in this place!

The students looked at the three masters in disbelief, a little puzzled by this, even though some of the students had already entered the Yin Acupoint, but what happened in this Yin Acupoint made the students not understand why

"Don't worry, these Yin Worms should be the same as some insects, they will die after breeding their offspring, and there are so many Yin Worms here, nine times out of ten, the offspring of these Yin Worms will be on the sixth layer, this is the first time we have seen this situation, find the way to the seventh layer as soon as possible!"

The three masters didn't react much, and the suspicion in the hearts of the students after hearing it was slightly alleviated, after all, these yin insects were all dead, but they just looked a little crazy

The six floors are basically filled with the corpses of the yin worms, and the students did not find anything superfluous, the entire six floors seem to have a feeling of extreme quietness, and the extreme silence makes the students' hearts involuntarily pinch up, not to mention the special yin and cold atmosphere in the yin cave here The impact on the spirit, inexplicably, the mood of the students has become a little depressed, even if the students themselves understand, but this is still unavoidable, and in desperation, they can only take a pill to prevent this negative emotion from affecting themselves.

"Wait!"

A voice sounded, and he said, although the sixth floor is not known to be as big as the fifth floor, but it is not small, how can there be nothing?

"What's wrong?" The master frowned and replied, they are already grandmaster-level masters, even women shouldn't make such a fuss!

Where did Song Xue think of this, this is the second time that Song Xue has been frightened in this yin cave, but this time it is not only frightened, but also doubts: "Master, look, is there anything on the corpse of that yin worm!"

Song Xue's voice was slightly surprised, but when the students saw it, they were also relieved, but the four students who knew couldn't help frowning, Xiao Zheng looked at this Yin insect that was the same as the Yin worm but was a little transparent and gray, and seemed to think of something in his mind

"Mutant Yin Worm!"

"Well, we haven't seen this mutated Yin worm yet, and we don't know what its characteristics are!" The master frowned and nodded, and then casually touched it

"Poof!"

A sound like piercing paper sounded, and the yin worm did not turn into ashes as imagined, but only the surface was pierced, and the master's face was even more ugly!

"Shall we go back first and get ready!" A master spoke, but the students did not interject, the masters have repeatedly said the importance of internal force to protect the body, don't look at the yin insect will be burned to death by internal force, but as long as it is bitten by the yin insect, it is basically the only way to wait for death, but now this half-gray and translucent yin insect has not been burned to death at one time, and the master has instilled demon power in the palm of his hand to completely cover this yin insect, and it took about a breath for this yin insect to be burned into ashes

"Three masters, shall we probe all this place first?" It was Mu Yi who spoke, and seeing that everyone was looking at him, Mu Yi couldn't help but smile and said: "This layer is already like this, and the Yin Worms are already dead, so let's first find out if there are other mutated Yin Worms here, and then we can leave after we are sure!"

"That's reasonable, then let's see if there are any other mutations of these Yin worms!" The master nodded, indeed, the overall situation of this now does seem to be a little different from the past, and there is a high probability that it is even deeper than the one in the academy!

The master led the students to continue to explore the sixth layer, and the sixth layer is obviously much smaller than the fifth layer, and soon found the second mutated yin worm under the leadership of the master, this yin worm is also the same as the previous one, it has a very strong resistance to internal force and demon power, and it can't be killed at one time, fortunately, after exploring for so long, the number of mutated yin worms is not much, and it can even be said to be rare, but when this layer was basically explored, Xiao Zheng found a corpse of a yin worm with a dark red body, The appearance of this Yin worm's corpse made the master no longer in the mood to continue exploring, and retreated directly.

Yin insect mutation Lin Yunqing and Huang Zongxi once said to Xiao Zheng that these mutant yin insects will always have some different abilities because of mutation, Xiao Zheng found that the red yin insects will be more toxic, and can spit out fiery red poisonous mist, while the gray translucent yin insects are the first time to see, except for the strong resistance to internal force and demon power, there are no other discoveries for the time being, in addition, there are many records of the students' mutation of the yin insects, such as the cold air on the head is heavy, and some yin insects have grown wings

The masters will definitely not joke with the lives of the students, this kind of yin worm that can resist internal force and demon power will definitely not hurt the students small, in case something happens, there is nothing to solve!

Today's events made the masters pay more attention, and what Xiao Zheng didn't know was that the students who went to the Snow Mountain today also made a huge discovery (to be continued......
