According to Nangong Wuji's "Distribution of Monsters in the Secret Realm", the rotten bone crocodile is just a fourth-grade demon beast, although it is a little difficult, it is not difficult to deal with.

However, judging from the strength of this rotten bone crocodile's blow just now, his strength was in no way inferior to that of a Jindan-level cultivator, if he hadn't had a defensive weapon like the Xuantian Shield, he would have been seriously injured if he didn't die just now.

The rotting bone crocodile missed a blow, flicked its tail, and rose into the air again, trying to chase Xin Yan.

The blue-eyed toad leaped and blocked the way of the crocodile. It roared and spewed out a purple poisonous mist that trapped the crocodile inside.

The blue-eyed toad likes to devour poisonous insects, and the purple poisonous mist it spits out is extremely poisonous, and ordinary monsters will die when they touch it. This rotting bone crocodile has been soaked in the poisonous miasma for many years, and has become a half-demon and half-corpse body, the purple poisonous mist not only cannot cause harm to it, but is a great supplement, it does not dodge or dodge, but greedily absorbs the purple poisonous mist.

The purple poisonous mist is condensed by the blue-eyed toad's natal true element, and every time the rotting bone crocodile absorbs a little poisonous mist, its vitality will be damaged by one point. In desperation, the blue-eyed toad sucked in violently, sucking the purple poisonous mist back into its body, along with the dead air from the carrion crocodile.

The death qi on the body of the rotting bone crocodile is extremely strong, and a little contamination will make the vitality wither, and in an instant, the blue-eyed toad looks sluggish, and its whole body is full of black dead air, and it is actually shaky.

The carrion crocodile stared at the incapacitated blue-eyed toad, its eyes flashing with hunger and thirst, and it didn't notice that a meteor-like flame in the sky was rapidly approaching it.

The green bull stared at the rotting bone crocodile, the sharp horns on its head flashed with dazzling cold light, and it swooped down rapidly, as fast as a meteor, with a long flame.

The carrion crocodile looked up sharply and found the green ox, its lifeless eyes flashed with a hint of fear, and with a flick of its tail, it was about to dodge.

But it was too late.

"Boom!"

The green bull was red gold all over, and with a thousand momentum, it bombarded the waist of the rotten bone crocodile.

The carrion crocodile was blasted to pieces, and the massive impact smashed it straight into the swamp.

The green ox's eyes were red, and it stopped in the sky like a god.

Seeing that the blue-eyed toad was about to fall into the swamp, Xin Yan shouted loudly, "Nirvana!"

Nirvana spun around and appeared beside the blue-eyed toad, with a flash of colorful light on its body, and it was collected into the five elements space in its body.

The carrion crocodile injured the blue-eyed toad, which made Xin Yan furious and wanted to chop it up directly. But the crocodile sneaked into the swamp with no trace, leaving him helpless.

Xin Yan drilled into Nirvana and inspected the injuries of the blue-eyed toad, only to see that the blue-eyed toad was eroded by the dead air, its vitality was withered, and the injury was extremely serious. Xin Yan saw that the blue-eyed toad was injured like this, and he was so distressed that he was going to die, so he hurriedly fed it a Nine Turns Soul Restoration Pill and three Five Dragon Pills, controlled its injuries, and let it recuperate in the Five Elements Space in Nirvana's body.

The blue-eyed toad is the most wooden among several foodies, and he rarely mistreats Xin Yan, and he has always been very happy with Xin Yan.

"If your brother hits you again, you have to break your bones. Xin Yan couldn't wait to tear down the bones of the carrion crocodile one by one to vent his hatred. However, although he was angry, he still had his senses. It would be unwise to entangle with a near-immortal demon beast like a rotten bone crocodile here.

What's more, he had a bad feeling in his heart, there must have been some abnormal changes in the secret realm, otherwise, how could a fourth-order demon beast like the Bone Rotten Crocodile become so terrifying.

The injury of the blue-eyed toad made Xin Yan blame himself, in order to avoid Nirvana and Xiao Hei also being injured, he put Nirvana into the dantian to recuperate, and only left the green ox outside to sweep the battle for him.

The vastness of this swamp far exceeded Xin Yan's estimate, and he flew for three hours, but still did not see the edge of the swamp.

The long-distance flight, even if he was as strong as Xin Yan, showed fatigue, and he decided to stop and rest.

Along the way, he always felt like some monster was following him, and in order to avoid being attacked, Xin Yan summoned Xiao Hei out and explained to him. Xiao Hei immediately understood, opened his mouth and spit out a large ball of Xuanshui, Xin Yan took out an ice talisman and slapped it on Xuanshui, and Xuanshui quickly transformed into an "Iceland". After Xin Yan and Xiao Hei worked together, "Iceland" became thicker and more than doubled in size, Xin Yan was still not at ease, and took another picture of the ice seal where he and Qingniu were standing, and also spread the [Yin and Yang Seven Evil Flags] on the ice in front of him, where the ice was the thinnest.

"Nirvana, you come to sentry!" Xin Yan ordered. Nirvana straightened up her fat body and nodded violently. Looking at its delicate and cute appearance, Xin Yan couldn't help but be happy, he touched Nirvana and threw a piece of material from the road to it.

When Nirvana got the material, he hid to the side and digested it.

"Nirvana, this is for you. Xin Yan threw two small pills to Qingniu, and Qingniu swallowed them in one bite, and then lay on the ice and closed his eyes to recuperate. Xin Yan changed the spirit stone for the trap bird, swallowed one himself, and began to meditate and breathe.

Suddenly, Xin Yan received the alarm signal from Nirvana, he opened his eyes suddenly, stretched out his palm and pushed on the ice, the whole person quickly retreated, almost in an instant, the ice in front of him exploded violently, and a dazzling white light rushed out from under the ice, opening his bloody mouth as if he was biting it.

Xin Yan didn't dodge or dodge, stretched out his hand a little, and the seven pillars of light rose to the sky, and the [Yin and Yang Seven Evil Array Banners] were instantly activated, trapping the rotten bone crocodile in the array.

Xin Yan was reassured, he carefully presided over the formation, firmly trapped the rotten bone crocodile in the formation, generally speaking, the best way to deal with the demon beasts was to trap them in the formation, and after their strength was exhausted, they could be cleaned up casually.

While it will take a little more time to do so, the benefits are also clear. First of all, you can avoid injury, the rotting bone crocodile is a half-demon and half-corpse monster, with infinite strength, incomparably poisonous, extremely strong defensive ability, and it is not easy to deal with, according to Xin Yan's estimation, let alone him, even if it is a cultivator in the condensation stage to subdue it, it is not an easy thing.

Secondly, if he can use the formation to take the rotten bone crocodile, he can get a complete rotten bone crocodile skeleton. The skeleton of the rotting bone crocodile is a magic weapon for healing, and the flying sword is difficult to hurt, which is the best material for making five-grade puppets.

After he became a small spirit, he always wanted to upgrade the machine man to the fifth grade, but he was unable to do so because the materials were difficult to find. Now that he encounters such a good material as a rotten bone crocodile, he is naturally unwilling to waste it.

Again, the Evil Qi on the Rotten Bone Crocodile's body is extremely heavy, and it is no better to use it to refine the [Yin and Yang Seven Evil Array Banner].

Soon Xin Yan felt that something was wrong, no matter how he changed the formation, the rotten bone crocodile could quickly find a way to live. It stands to reason that the Rotting Bone Crocodile is a half-demon and half-corpse murderous creature, and it is impossible to be proficient in the formation at all.

"Could it be that this rotting bone crocodile has actually absorbed the soul of a cultivator who is proficient in formations?" Xin Yan had a very ridiculous thought in his heart.

As if to prove that Xin Yan's idea was correct, the rotten bone crocodile actually found Xin Yan who was guarding the life gate before Xin Yan changed formations. However, now is obviously not the time to study whether the Rotten Bone Crocodile is really devouring the soul of a cultivator, and the top priority is to stop the Rotten Bone Crocodile.

Xin Yan didn't entangle with the rotten bone crocodile, he used all his strength to carry the [Wind Technique] and retreated, and at the same time called out loudly: "Green Ox! Block it!"

The green bull turned into a streamer, fell from the sky, and slammed heavily on the back of the Bone Crocodile, causing its flesh and blood to fly, and blasting the Bone Crocodile back into the formation.

But soon, the rotting bone crocodile burst out of the door again, and its whole body exuded a ferocious and violent aura, staring at Xin Yan with its eyes, and rushed towards Xin Yan.

This time, without Xin Yan's greeting, the green cow let out a low roar, turned into a streamer, and rushed past the side of the rotting bone crocodile. The rotten bone crocodile can have such a fierce reputation, and it is not easy to provoke, its body swings, like the tail of a steel whip, with a tearing whistling sound, rising from the ground. "Boom!"

Its tail and the sharp horns of the green bull slammed together. The green bull bombarded this time, how powerful it was, and the rotten bone crocodile was knocked into its flesh and blood, and it fell back into the formation heavily.

Xin Yan controlled the large array with all his might, preventing the rotten bone crocodile from easily protruding from the large array, but it was only two pillars of incense time, and it broke into the birth gate again.

The green bull, which had been guarding the living gate for a long time, turned into a streamer of light again and crashed into the rotting bone crocodile. The attack of the green bull completely aroused the ferocity of the rotting bone crocodile, it opened its bloody mouth and rushed towards the green bull, the two rows of staggered sharp teeth were like giant pincers, flashing with cold light, seizing people's hearts!

"Boom!"

A red light and a white light and shadow are like two meteors, colliding together!

Thunder!

The green bull and the carrion crocodile were bounced off at the same time, and both fell backwards at a faster speed!

That's it, but in just half an hour, the green cow and the rotten bone crocodile have fought seven or eight times, and what shocked Xin Yan was that the rotten bone crocodile would be hit to the flesh every time, but it did not weaken its strength, but became more and more courageous. Every time it is injured, the death qi on its body will be thickened by one point, and its strength will also increase by one point.

The careful Xin Yan found that with the collision again and again, the flesh and blood of the rotting bone crocodile became less and less, and in the end, there was almost only a skeleton left.

"Oh no. Xin Yan suddenly remembered an introduction about the Rotten Bone Crocodile in the Jade Slip: The more the flesh and blood of the Rotten Bone Crocodile were eroded by the death qi, the higher the grade and the stronger the strength.

Sure enough, after another violent impact, the flesh and blood on the carrion crocodile's body completely disappeared, leaving only a crystal white skeleton, which was filled with a dead air that was so thick that it almost condensed into substance. The rotting bone crocodile suddenly let out an extremely piercing roar, like an ancient fierce beast, and a powerful power rippled far away.

Xin Yan's face darkened suddenly, and he had inadvertently helped the Rotten Bone Crocodile achieve a promotion.
