The Xuanhan toad poison is easy to understand, it is the same as the fiery toad, but the attributes are opposite, the toad poison of the fiery toad contains fierce fire poison, and the Xuanhan toad poison contains a domineering cold poison.

It's just that this spirit erosion piercing, Lin Feng doesn't know very well what has changed.

If you don't know something, you always have to give it a try, this is Lin Feng's consistent practice.

The eyes fell on a Xuanyan toad next to him, although it is also a kind of toad demon beast, but this thing is famous for defense, the skin behind it is like a rock, and the skin on the body will be blessed by demonic power when it is defended, and the hardness is comparable to Xuanyan, so it is named Xuanwu toad!

Isn't that a good target?

"Brother, I'm sorry!" Lin Feng mourned silently in his heart, but his mouth was merciless!

Whew, a phantom accurately hit the basalt toad, and in order to detect Lin Feng, it specifically aimed at the thickest part of its skin!

I saw that the basalt toad screamed, and the invulnerable hard rock skin behind it was actually dissolved into a hole by Lin Feng's tongue and stabbed directly into the body.

"Spirit Eclipse, it turns out that this is Spirit Eclipse!" Lin Feng's eyes lit up.

He could see clearly now that when he was attacked, the skin on the Xuanwu toad's body became darker, and a faint yellow halo appeared, which was a manifestation of the blessing of demonic power.

However, the saliva on his tongue actually contained a strange energy, which directly eroded the demonic power blessed by the basalt toad, like a hot knife cutting into butter, making its hard defense like an ornament.

"In this way, isn't my tongue attack power off the charts?" Lin Feng's heart was hot.

You must know that most demon beasts, especially those with strong defense, are basically the result of the blessing of the body by demon power, as long as a very few are because of the special bloodline contained in them, resulting in a particularly strong physical body.

The saliva on Lin Feng's tongue could easily erode demonic power, which meant that these defenses were simply a joke in front of him.

But trapped in this place, sooner or later he will wait for death, in case this old witch lacks an alchemy material or something, even Lin Feng, who is currently advanced, is not the opponent of this old woman.

As for the green snake, Lin Feng was also a little confident at this time, after all, the green snake had not grown up at the moment, and it was also in the strength of a third-order demon beast, and below the same level, Lin Feng was really not very afraid.

It's just that the green snake is gone, and I don't know if it ran out to forage for food, or where it went.

"How can I escape?" Lin Feng kept his chin on his paws and looked up at the formation above his head.

Looking at the pool shrouded by the formation, Lin Feng tried it, and hit it with all his strength, but at most it caused a few ripples in the formation, and he couldn't break through at all.

It's still too weak!

Lin Feng sighed, then swallowed the Xuanyan toad that he had killed in one gulp, and smacked his mouth.

The taste is not good, but there is a growth point, and the mosquito legs are also meat.

Looking at the 3-point growth points in many places in the system panel, Lin Feng sighed in his heart, the third order advanced to the fourth order, it took 10,000 growth points, which would cost him his life.

A fourth-order blue water Jiao is only 1000 growth points, and he has to devour 10 to advance, isn't the system too dark?

As everyone knows, when Lin Feng was thinking about life with his mouth open, the other toads trembled, and quietly moved away from him, so as not to be swallowed by this terrible guy.

"No, demonic power is also a type of spiritual power, since my tongue can erode demonic power, why can't it erode spiritual power?"

Suddenly, Lin Feng's eyes lit up.

Lin Feng took a cautious look, the old witch was still cultivating in her cultivation room, and it was estimated that she would not come out for a while.

He jumped to the edge of the poolside formation and tried to attack one of the points of the formation with his tongue.

Sure enough, the originally sturdy formation light shield was gradually eroded out of a hole like ice and snow at the point where Lin Feng's tongue attacked.

But if the forest wind stops attacking, the eroded area will slowly recover, and finally return to its original state.

After half an hour of unremitting efforts, Lin Feng struggled to squeeze out of the dissolved gap.

He was afraid that the erosion would cause the formation to collapse if it was too large, and that he would be dead once the old woman was alarmed, so he was very careful to dissolve only a fist-sized gap.

"Old, Lao Tzu, finally, it's finally out!" Lin Feng stammered.

For half an hour, my tongue kept licking, and I couldn't stand it even if I was a macho man!

Lin Feng rubbed his numb tongue, he felt that if he had been so powerful, he would have chased the school flower a long time ago.

"No one should be able to see it, right?"

Seeing the gap behind him that was made by himself slowly closing, Lin Feng breathed a sigh of relief.

The low-level demon beasts really seemed to be relatively low in terms of intelligence, and when Lin Feng secretly escaped from prison, none of the other toads escaped with him.

I don't know if it was Lin Feng's previous ferocious appearance that scared his kind, or if the deterrent power of the green snake was too great, so they didn't dare to escape from prison easily.

Fortunately, Lin Feng was lucky, the cave was empty, not only was there no figure, but the green snake was not there.

In fact, the interior of this cave is very large, but most of the space is used to house all kinds of poisons, so it will be a little crowded.

Thanks to this Li Qing's fierce reputation, the cave mansion did not even have a single disciple except for Li Qing and the green snake, which made Lin Feng's escape from prison very smooth.

Lin Feng, who had already walked to the door, remembered that he had been arrested for some reason, and he was almost eaten as a snack, and he was already so aggrieved that he couldn't do it.

The more I think about it for a while, the more angry I get, and the more I think about it when I take a step back, the more I lose!

Lao Tzu just ran away, and if he didn't give you some color, wouldn't it seem that Lao Tzu was very faceless?

Thinking of this, Lin Feng turned back and jumped back.

Looking at the pool densely shrouded in formations, Lin Feng suddenly had another thought, and after laughing twice, he began to sneakily investigate carefully in the cave mansion.

Since there is a formation, then there will naturally be an array eye, as long as the formation eye is found, and then the formation eye is destroyed, then won't all these formations be invalid?

At that time, the formation will fail, and these countless poisonous insects will be out of control, which will definitely be very exciting!

Lin Feng quickly investigated, he knew that he was very short on time, once the old witch came out to inspect, or the green snake came back, then his plan would not be realized.

Soon, Lin Feng came to a stone platform in the depths of the cave, this stone platform was very special, carved with complicated patterns, and there was a fist-sized pale white halo stone floating on the stone platform.

The rich aura power slowly emanated from the stone, and was absorbed by the stone platform little by little.

"This should be the hub of the formation, right?" Lin Feng muttered secretly.

The formation needs spirit stones to provide energy, and most of the caves are searched, and Lin Feng only finds this place to supply spiritual power.

"Sleep you are paralyzed, give me a high spirit!"

With a wicked laugh, Lin Feng stretched out his sinful tongue......
