The creatures of the Demon Realm, who have developed wisdom, will also choose the path of cultivation to prolong their lifespan. The cultivation of the demon realm is divided into nine levels, and only when you cultivate to the sixth order will you have mana, and after you have mana, your body can evolve into a human form, so the sixth order becomes a transformation. The seventh order is called the Demon King, the eighth order is called the Demon Emperor, and the ninth order is called the Demon Saint! The Demon Realm is a realm where all kinds of creatures are mixed, including human beings, ghosts, monsters, and homegrown monsters! Because whether it is a human, a ghost, or a demon, as long as they cultivate demonic skills and cultivate mana, they will be led to the Demon Realm to continue their cultivation. When a monster cultivates to the ninth order of the Great Perfection, it will become an immortal and ascend to the immortal realm! Once it ascends to the immortal realm, it is the same as a monk becoming an immortal, and is collectively referred to as an immortal.

The demons of the demon world, according to their different sources, are divided into four categories, from the human world to the past are called human demons, from the past of the demon world are called demons, from the past of the demon world are called demons, and from the demon world to the past are called demons, and the demons born and raised in the demon world are called the main demons. The demons are collectively referred to as monsters. Among the four types of monsters, demons are a very special category, no matter what level the demons cultivate, they can't transform into human form! For example, the Blood Spider Demon King that Geng Qiang encountered when he first arrived at the Demon Realm, although he had reached the realm of the Demon King, he still couldn't transform into a human form. Legend has it that only by reaching the divine realm can demons transform into human form. And the other three kinds of demons, except for the human demon, which was originally made by human beings by cultivating demonic skills, the demon is the existence of the soul after the death of a person, so it is also a human form, and the demon can also transform into a human form when it reaches the sixth order.

Now, the big rat that Qin Yan and Li Hui encountered was a fifth-order Great Perfection Demon, who could have cultivated mana, shed its fur, and advanced to the sixth-order transformation as long as it took that 10,000-year-old Shou Wu. However, since the Shouwu was not eaten, there was no advancement, so he could only rely on his body to fight.

The big rat dodged Qin Yan and Li Hui's attacks, although it looked easy, just a gesture, but its head was swinging and retracting, and it was no longer able to dodge the sudden sword of the team member!

But at this critical juncture, the big rat suddenly hissed at that Lingyun disciple!

"Squeak!"

The cry of the rat was already terrifying, and in addition, the Lingyun female disciple lacked combat experience, and at this time, this thing roared with all its strength, which actually frightened the Lingyun female disciple, and the sword in her hand suddenly stagnated!

In a duel, the fighter plane is often fleeting! If one is not careful, it will often be overturned! The big mouse immediately seized the opportunity and grabbed it from the right and poked out! It actually grabbed the sharp blade of the team member at once! The big mouse actually cut through its huge claws despite the sharp blade, and swept its left paw from left to right against the tall chest of the female team member! The mouse was still thinking in his heart: "Damn, I want to disembowel your grandfather Mouse! Lao Tzu will disembowel you, and you will be embarrassed to die!"

Qin Yan and Li Hui looked at it, and they were horrified, and secretly thought: "It's over, I'm afraid this team member is going to return to the west!" Although the two of them thought so in their hearts, neither of them gave up their efforts, Qin Yan raised his foot to the left side of the big mouse is a side whip leg, and a sharp outward deflation force smashed straight towards the big mouse! Li Hui was not idle, his right hand shook, and the originally soft Cailing in his hand instantly turned into a stick as solid as steel! Then, from right to left, he suddenly smashed towards the right side of the big mouse! The two of them became a left-right attack on the big mouse!

The two of them thought well, and their cooperation was quite tacit, and they wanted to seriously injure the big rat under the left and right attacks, so that the big rat would no longer be able to attack the team member! But the two muttered about the big mouse's ability to resist attacks! The big rat directly ignored the attacks of the two beauties, and continued to tear the chest of the team member desperately!

Seeing that the opportunity was not good, the team member threw away the sword in his hand, and fell backwards violently, trying to avoid the big mouse's grasp! However, her movements were half a beat slower than the big mouse's! Although she dodged the mouse's claws, she did not avoid the sharp nails on the claws!

In the blink of an eye, the big mouse and the female disciple were hit at the same time!

"Huh!" In the cracking sound, a piece of clothing and flesh flew up from the female disciple's chest with flesh! Fortunately, the female disciple made a dodge move before being hit, otherwise her pair of huge mias would have to be torn off directly! Even so, the female disciple was not lightly injured, and she fainted to the ground with a miserable scream!

The big rat didn't have a good time, and after taking two tricks from Qin Yan and Li Hui, a mouthful of blood spurted out of his mouth. However, this aroused the ferocity of the big rat even more! he roared again and again, turned around and pounced on Qin Yan and Li Hui!

The huge body, the bloody corners of the mouth, and the terrifying roar actually made Qin Yan, who had always been a little strong, feel his scalp tingle! Fortunately, at this time, the other members of the first squad had already rushed over, and everyone stopped the big rat together! Although it was in a dense forest, fortunately, this place was relatively spacious, and everyone could use their fists and feet to use their weapons, otherwise I am afraid that Qin Yan and the first squad would only be broken by this big mouse.

Although the battle with the big mouse just now was only a momentary thing, Qin Yan felt a kind of physical and mental fatigue! Although Qin Yan had fought with others before, it was the first time he had encountered a fight of this level! Moreover, he was still fighting with a mouse! Li Hui was not much better, and he was a little out of breath!

The tired two didn't have time to rest, Li Hui walked quickly to the female disciple who fell to the ground to check her injuries, while Qin Yan picked up her spirits and pounced on the big mouse again.

The ferocious big rat obviously didn't have the slightest sense of pity for the jade, and under the attack of the nine beauties, he moved his hands and feet together, even tearing and digging and gnawing, his movements were fast, fierce and abnormal, and every move was aimed at the vital points of the beauties!

Although the big rat is fierce, but after all, it has not yet reached the sixth order of transformation, it has not yet possessed mana, it is still flesh and blood, and after a long time, the big rat is also a little unable to parry, his whole body is scarred, bloodstained, and the movements between opening and closing are no longer as fast as they began at the beginning, and the strength brought up by the sharp claws has not been violent at the beginning.

"Come on, sisters, this rat has reached the end of its crossbow! It's about to finish! Sisters, work hard!" Qin Yan saw that the big mouse was defeated, and hurriedly cheered up the sisters in the battle!

"Kill!" everyone shouted in unison, surround the rats, and destroy the big rat!

Just when everyone thought that this huge rat was going to die at their hands, a mutation suddenly appeared! The rat, which had reached the end of the crossbow, suddenly roared again and again: "You despicable human beings! If you rob me of my things, you will kill me! Today, even if I die, I will pull you to your back! The great demon will not die alone!"

After roaring, the big mouse suddenly fell straight to the ground and did not move! Even its heart stopped beating, and blood continued to flow out of its seven orifices and wounds, staining the forest floor red. It seems that this big rat is dead and can't die anymore!

Qin Yan and the others, after listening to the words of the big mouse, they thought that this big mouse was going to die with everyone. I didn't expect it to commit suicide! It just didn't move! Everyone walked towards the big mouse step by step, wanting to see if the big mouse was dead or not. Because he hadn't heard Geng Qiang say that this big rat could refine any elixir, no one planned to bring the corpse of this rat to Geng Qiang.

At this time, Li Hui had already revived the previous female disciple, and after treating her, she bandaged her wound again, and then she also followed everyone around!

Just as everyone was getting closer and closer to the corpse of the big mouse, the big mouse's stomach suddenly exploded, and a round ball the size of a jet-black watermelon burst out of its belly!

"It's not good!Neidan! This is Neidan! This dead rat is going to blow up Neidan! Everyone hide!" Qin Yan said in shock! It turns out that when the monster cultivates to the fifth order, it will produce Neidan, which is equivalent to the solid true yuan ball of a human monk. It is the place where mana will be generated in the future! Neidan, like the solid true element ball of a human monk, contains great energy, and it can be said that it is a place where a monk has cultivated all his life!

It is precisely because of the terrifying power contained in the inner dan, so once the inner dan of the monster explodes, the destructive power brought by it is quite terrifying! Before coming to the demon world, Geng Qiang once told everyone about it, but because Geng Qiang had never seen the inner dan of the monster, when he explained it to the disciples of Lingyun, he didn't say it in too much detail, but just put the "Heavens and Ten Thousand Worlds" The things recorded in the book about the monster Neidan were briefly talked to everyone, so everyone didn't take it to heart, only knowing that the monster Neidan can explode, and the power is still great! What's worse is that everyone thinks that the monster can only spit out the Neidan and explode itself when it is alive. It's as if people can only eat and sleep while they are alive. I didn't expect that the big mouse in front of me could only spit out his Neidan after death!

At this moment, everyone couldn't help but be taken aback when they heard Qin Yan suddenly shout that the black thing that came out of the belly of this dead mouse was the monster Neidan!

Although Qin Yan reminded everyone, in the face of this kind of Inner Dan explosion, even if everyone is ready to run away first, and then let this Inner Dan explode, I am afraid that everyone will not be able to escape the killing range of the Inner Dan self-explosion, not to mention, everyone will be suddenly attacked!

At this moment, everyone including Qin Yan had no way to retreat, and there was no way to escape! There was really only one way to die! At this moment, everyone was thinking, "It's over, I knew that I would die when I entered the Demon Realm, but I didn't expect that it was me who died!"

"Hahaha, it's so moving!"

Just when everyone fell into absolute despair, and could no longer make any reaction, only to close their eyes and wait for death, suddenly a long laugh came into everyone's ears! Then everyone saw a flower in front of them, and a figure flew in, and as soon as he stretched out his hand, he grabbed the inner dan that was about to explode in his hand, and then he actually swallowed the monster inner dan in his mouth like eating peanuts!
