"Why is there a dragon lying here? Could it be that this poisonous mist is emitted by him?" Yue Ting tried to check the dragon's head, but found no place to emit poisonous gas.

"Maybe it just died here. Mu Yi guessed, "You see that there are scattered weapons everywhere here, when the Great War of the Divine Realm was first made, the two factions of immortals and demons must have experienced a fight here, and this dragon may be the mount of one of the parties, and finally died here." ”

Yue Ting disagreed with him, shook his head and said, "If that's the case, why are the monk's corpses gone, and the dragon that is the only one used as a mount is still there? Are the poisonous insects and poisonous beasts here picky eaters? They only like to eat people?"

Yue Ting's mention of this made Mu Yi a little enlightened: "That's right, and if this poisonous mist is really emitted by some living poisonous insect and poisonous beast? What have they relied on to survive for hundreds of millions of years? The aura here is very thin, presumably this space is not in a place with abundant aura, and it can't last for so long." ”

"You mean that this poisonous mist has always existed here, not from a living beast?" Yue Ting hesitated, "But what poisonous mist can exist for so long, what kind of formation is it?"

"I don't think so. Mu Yi shook his head, "And don't you think it's strange that we fell into the illusion just now, I always feel that this is not like a human demon's doing, there is a thick fog everywhere here, and the danger in the dark will appear at any time, and he is timid by nature, he is always hiding behind the heavenly and earth demons, and it is unlikely that he will take the risk of attacking others here." Moreover, except for the old drunkard, the monks who were attacked were only cultivators below the god level, but they were just small minions, and he didn't need to use this method at all. And the old drunkard's scar was obviously not his doing, but the sword wound and fire mark reminded me of a person. ”

"Who?"

"One of the three decent, Dao Zun Zuo Qingfeng. Mu Yi pondered, "He uses a sword, and he is good at Samadhi True Fire, the sword wound on the back of the old drunkard is just similar to his long sword, and that fire mark is obviously not ordinary fire, and those who can hurt the old drunkard are afraid that only the level of Samadhi True Fire can." ”

"Isn't that just right? The human demon took advantage of Zuo Qingfeng and the old drunkard to be together, and used the heart punishment technique to confuse Zuo Qingfeng to kill the old drunkard, and the old drunkard fled to us after being injured. Yue Ting tilted his head and thought, feeling that there was nothing wrong.

"But that's not his style. Mu Yi frowned and said, "I met a friend before, called Fox No Return." He told me that humans and demons are very vulnerable, and even the monks in the early stage of the tribulation may not be able to fight in terms of fighting, so they have been hiding behind the heavenly demons and earth demons, and they will not attack easily. Once he makes a move, there must be a heavenly demon or an earth demon by his side, and at that time, he will bewitch the enemy's mind, and the heavenly demon or earth demon will solve the opponent, and there will be no disadvantage. And the old drunkard doesn't have the scars of these two people's weapons on his body, so I don't think the human demon will do anything to the two righteous Venerables alone. ”

"It's kind of weird to say that. Maybe the human demon took advantage of this complicated environment and was bold?" Yue Ting somewhat agreed with Mu Yi's judgment, but was not very convinced, "If it wasn't done by the human demon, then how can this matter be explained, who did those dead monks do, and why did we fall into the illusion?"

"That's why I don't think it's a human or a demon. Mu Yi's thoughts gradually began to become clear, "We have no grievances with humans and demons, this deal is meaningless, I suspect that this illusion has something to do with this fog." ”

"Does it have anything to do with this fog?" Yue Ting frowned, he really couldn't connect the two.

"Yes. Mu Yi firmly believed in his judgment, "Although this mist is poisonous, it is easy to crack, as long as there is a shield or detoxification pill similar to ours, it is fine, and it is only a matter of time for the master to help me detoxify." This is where the mountain protection array of a certain big sect in the fairy world is located, how can it be just so capable, I suspect that this mist is poisonous just a pretense, and the real killer is this illusion. ”

"But I've never heard of hallucinations caused by fog. Yue Ting shook his head, "It's okay for poisonous gas to make people hallucinate, but we have completely blocked the poisonous gas." ”

Mu Yi recalled: "It's not that the fog causes hallucinations. When I was fighting in the Tocharian Desert in Great Xia, I had heard that if there was fog in the desert, there would be a strange phenomenon - a 'mirage'. ”

"I've heard of this, and it seems to happen when there is fog in the sea. Yue Ting had also heard about this and nodded.

"Yes, the phenomenon of mirage has been explained on Earth, when light is refracted into small water droplets in the fog, reflecting the distant scene in front of our eyes. This phenomenon itself is not very important, but the origin of the name is very particular. ”

"What's so exquisite. Yue Ting asked.

Mu Yi recalled: "The word 'mirage' in the mirage is the key to it. It is said that in ancient times, there was a strange beast called 'mirage', which is the direct descendant of the ancient dragon, they generally inhabit the sea, they are huge, slender and meandering, can spit poisonous gas, forming a long white mist, people will fall into hallucinations in the mist, see all kinds of scenes, and finally fall into the mirage and become its food. Later, the mirage became extinct, but people also called the phenomenon of appearing out of thin air 'mirage'. ”

"Are you saying this thing is a mirage?" Yue Ting suddenly realized, "Listening to you say that, it's very reasonable, this mirage dragon emits a mist here, causing the intruders to hallucinate and kill each other, and then it eats the corpses of these people as food, no wonder it only saw the scattered weapons and traces of the fight before, and couldn't see the corpses." ”

"I feel like I'm not far from ten. Mu Yi nodded, "This mirage dragon must be the mountain protection beast of this sect, when the gods fought in the first war, when the enemy attacked here, many people died in the hands of the mirage dragon and were eaten by it as food." Later, there must have been a powerful power that killed it here, so I only saw its corpse, but not the corpses of other ancient immortals. ”

Mu Yi was suspicious: "But why hasn't this fog dissipated after hundreds of millions of years? and can continue to hallucinate? ”

Mu Yi said firmly: "This is normal, you see that this is an isolated space, and the fog has nowhere to dissipate, and I feel that there should be a formation to trap the fog here." The mirage is a very peculiar dragon species, if you make a candle out of mirage oil, it can still make people fall into an illusion after lighting it, but the effect is much worse. This shows that even if the mirage is dead, the mirage can still play a hallucinogenic role. ”

Mu Yi's words perfectly explained the problem encountered by the two of them, Yue Ting was already completely convinced at this time, patted the mirage's long mouth and said: "How can you say that this thing is also an ancient xenomorph, you said that refining the pill can help me improve my meridians." ”

"It is very likely that the mirage dragon is closer to the bloodline of the ancient mirage than the green dragon and the giant ape before it, and his skin, flesh, muscles and bones must be good. ”

"So what are you waiting for? Yue Ting's eyes lit up, and he took out the long sword from his waist and began to slash.

But this dragon body is too hard, and it has no effect after he has spent a long time. Mu Yi manipulated the flying sword and tried it, but he couldn't break through the scales on the surface of the mirage's body.

"It's worthy of being a divine beast in the fairy world, we are tigers eating the sky - we can't eat it." Or move back to our mountain gate, just as a mountain beast. Yue Ting wiped his sweat and said.

"Don't. Mu Yi was taken aback, "How big is our mustard seed space, you have to put this mirage in its entirety, the whole space will be filled with this poisonous gas, let's be okay, what should those children do." ”

"It's also ha. "It's not left, it's not right, Yue Ting couldn't help but have a toothache, "What can I do, why don't you just leave empty-handed with such a good opportunity?" ”

"Big brother, don't worry, since this mirage dragon was killed by someone, I think there will definitely be a wound, let's look for it. Mu Yi pulled Yue Ting around the other side of the mirage, and sure enough, he found a pool of blood under his neck.

"It is said that the dragon has reverse scales, which are its lifeline, just under the neck, and it must have been the power that caught the reverse scales of this mirage dragon and killed it with one blow. Mu Yi analyzed.

But the dragon was lying down, and the wound was crushed under it. It's too big for us to move. Yue Ting spread his hands and said he was helpless.

"Hehe, don't forget that Lin Zi is best at making holes. We can't move this mirage, we can burrow underneath. Mu Yi laughed twice and summoned the middle forest of the mustard seed space.

Lin Zi has been following Tan Yuan to strike iron for decades, and he has long been bored, and when he heard that Mu Yi wanted him to do his old job, he took out his fist blade without saying a word, and dug a big hole in the ground that was one person wide, leading to the neck of the mirage.

"Brother Mu, you see it's here. Lin Zi pointed to a wound on the dragon's neck and said to Mu Yi. This wound is crescent-shaped, the section is very neat, and the flesh and blood inside can be faintly seen.

"It is said that the dragon's reverse scale is crescent-shaped, and this should be it. Mu Yi nodded, "I just don't know where its reverse scales have gone." ”

"Leave this to me, I guess it's being pressed somewhere. Lin Zi patted his chest to stop the work, and volunteered to continue digging.

Mu Yi instructed Yue Ting to take some flesh and blood from the mirage's wounds, and there were not many materials needed for alchemy, so it was not a trouble.

But Yue Ting got into the dragon's belly and didn't come out for a long time, and the anxious Mu Yi almost went in to find him, just when he was impatient, Yue Ting crawled out of the hole covered in blood.

"Second child, look what this is. As soon as Yue Ting came out, he excitedly sent a milky white bead to Mu Yi.
