Mu Yu's arm was already broken, and he could only hold the flying sword in his left hand. Normally, the Shadow Splitting Sword can be turned into five, and the left hand and both hands can actually be used, but the sword is not as smooth as the right hand with the left hand, and once the right hand is broken, the strength he can exert is reduced by five layers.

The sound behind it seemed to be coming from the water, as there was the sound of splashing water. Judging from the sound, the volume of this demon beast should not be very large, more like an agile demon beast. When the tentacle-like thing wrapped around Mu Yu, Mu Yu wailed in his heart, it's over, it's an octopus monster again.

But something was wrong, at the moment when the tentacles wrapped around Mu Yu, Mu Yu had a familiar feeling in his heart, this feeling was so joyful, so real, he didn't feel the breath of death, but let him see a glimmer of hope.

It's a water weed!

I never expected that this time it was actually a moving aquatic weed! The other party would move again, and it was a plant, and it was a plant that Mu Yu could control. This aquatic plant is also unlucky, it just came to join in the fun, who wanted to kick the iron plate. As soon as the aquatic grass came into contact with Mu Yu, he knew that he had met his nemesis, and it was directly taken down by Mu Yu without even having a chance to resist.

"It's saved!" Xiao Shuai said happily.

Mu Yu also pinched a handful of sweat, the mountains and rivers were full of doubts, and the willows and flowers were bright and another village. He immediately uprooted the aquatic plant from the water, and estimated that this aquatic plant was a round body, two fingers thick, covered with barbs, and about ten meters long, which could be regarded as a powerful killing weapon. If there are still demon beasts that don't have long eyes to come over to make trouble, they will directly integrate into the aquatic plants, and there should be no accidents.

Mu Yu found that Lao Tan's fire had not been extinguished, but it was also flickering, and Lao Tan's angry shouts were heard, Lao Tan must be fighting with a lot of demon beasts now. He knew that he could not afford to delay, so he hurriedly ran forward, his body wrapped in aquatic plants, his eyes looking into the darkness ahead, and he was always on guard.

At this moment, Mu Yu's eyes lit up, and he saw the light in front of him! Lao Tan's firelight really ran from behind Mu Yu to in front of Mu Yu, which means that Mu Yu had just crossed the boundary of this maze.

Mu Yu took a step back, the firelight was still in front, and after taking another step back, the firelight disappeared.

This is it!

Mu Yu crouched down, and in the darkness he couldn't see anything, and he couldn't see the ground. Mu Yu took out Xiao Shuai's leftover bones, placed a cross on this side, and then moved a few pieces of the goose soft stone away, made traces, and finally groped for the wall and carved marks on the wall.

Everything was marked, Mu Yu stood up, and just wanted to run in the direction of Lao Tan, and returned to the cave with Lao Tan to wait for the dawn, but Lao Tan heard a loud roar.

"Mu Yu, if you solve the maze, you must take my corpse out, I don't want to stay here after I die!"

Then the firelight flickered a few times, and then it was extinguished, and the surroundings were reduced to darkness again, except for the roars of demon beasts.

Mu Yu's heart sank, Lao Tan was besieged by many demon beasts, and he couldn't hold on, and it was estimated that he was more than lucky at this time. Mu Yu wanted to run over to save him, but the light was blind, and it was useless for him to go, and he didn't know where Lao Tan was.

He felt a burst of sadness, Lao Tan had an accident, and he felt very uncomfortable. Lao Tan has been trapped here for more than half a year, and if he dies here in such a way in the end, then God is really unfair to him.

Mu Yu didn't dare to move, if he continued to walk, he would definitely encounter more demon beasts, he had to find a suitable place to rest now, and wait for dawn to make plans.

Mu Yu controls the aquatic weeds and makes them firmly attached to the wall, and then Mu Yu makes the aquatic plants make a hammock and lie on it by himself. He pricked up his ears vigilantly to listen to the movements around him, and from time to time there were strange sounds on the riverbank below, like some monster beast crawling rapidly, and like some monster beast rolling and playing.

"These demon beasts shouldn't climb up, right?" Mu Yu silently prayed in his heart that Lao Tan would not have an accident, and also prayed that those demon beasts would go back to the river to sleep quickly, if there was something to do, it would be true that they would come out at night to make a lot of fun.

This night, Mu Yu definitely couldn't sleep, he lay on the water grass, a little reluctant in his heart, and listened to it from time to time to see if there was still Lao Tan's voice calling for help in the distance. He really wanted to hear Lao Tan's cry for help, but at the same time he was afraid to hear it, because even if Lao Tan was calling for help, Mu Yu had no way to save Lao Tan, and it would only add to his own trouble.

"I've taken your fracture in the middle, and it should be healed tomorrow morning. Xiao Shuai shook his big tail, his high efficiency made Mu Yu breathe a sigh of relief, this was the only luck that made Mu Yu feel unlucky, at least if there was another demon beast attack, he could barely cope with one or two.

The valley in the dark night was bustling, these monsters did not dare to run out of the water during the day, and at night it was like a party, tearing and roaring at each other, making all kinds of noises.

Finally, when it was dawn, Mu Yu saw the sound of water splashing in many places, and the flowing water began to rattle, presumably the demon beast crawled back to his underwater lair. Mu Yu waited until there was no longer the sound of demon beast activity below, and then he jumped down cautiously.

He didn't put the aquatic plants back into the river, thinking that if a lone demon beast came to attack him, the aquatic plants would still be used. But the aquatic grass suddenly had a hint of panic, and as the sky grew brighter, the sense of urgency it conveyed to Mu Yu became stronger and stronger, as if the aquatic grass was afraid of the day.

"Are you saying that there is some kind of strange poisonous miasma in the valley during the day that makes you feel uncomfortable?" Mu Yu nodded thoughtfully, no wonder he couldn't see a demon beast during the day, it turned out that there was a poisonous miasma that made the demon beasts fear in the valley during the day. Presumably, these poisonous miasma are white mist, but Mu Yu is also very curious, because he and Lao Tan did not feel strange in this mist, and it was said that Lao Tan had been here for half a year without any accidents.

The aquatic plants had begun to tremble, and the white mist was becoming more and more obvious, so Mu Yu had no choice but to put the aquatic plants back into the river. As soon as the aquatic plants fall into the river, they leave a ripple like an amnesty and disappear.

"Old Tan!"

Mu Yu ran in the direction of Lao Tan, and at the same time began to shout loudly for Lao Tan. His voice echoed in the valley for a long time, but he didn't hear Old Tan's response. He stopped in a place full of blood.

Red and blue blood was scattered on the ground chaotically, and there were many mutilated and severed limbs, which looked very much like demon beasts. This should be the place where Lao Tan fought with the demon beast last night, and from the bloodiness of the scene, it can be seen that there was a tragic battle here last night.

Mu Yu endured vomiting to check those blood clots, silently thinking in his heart that he would never see blood clots similar to human bodies. Fortunately, he opened the blood clot and didn't find any signs of Lao Tan, which made him breathe a sigh of relief. But soon he became worried again, could it be that Lao Tan had been gnawed by the demon beast and there was nothing left?

Mu Yu tried to get this thought out of his mind, he was unwilling to accept this fact, and continued to look to the side.

But after searching for a long time, he didn't find anything about Lao Tan, could it really be that he had been buried in the belly of the demon beast? He walked to the cliff wall and sat down, feeling very guilty. He came up with this method and caused Lao Tan to be killed, not to mention how sad he was in his heart. Last night, Lao Tan shouted with his last breath to ask Mu Yu to take Lao Tan's corpse out, and now there is not even a bit of scum left, how to bring it?

"Let's go!"

A drop of blood dripped on Mu Yu's arm, which looked so shocking. Mu Yu reflexively stood up and looked up, thankfully, Lao Tan was actually on the cliff wall.

"Uncle, are you okay?" Mu Yu found that Lao Tan had inserted two short blades into the cliff wall, so he grabbed these two short blades and hung them on the stone wall and held on for a night.

"Great, you're okay. ”

Lao Tan opened his eyes weakly, saw that it was Mu Yu, and finally breathed a sigh of relief, and then let go of his hand, and the whole person fell. Mu Yu reached out to catch it, but his hand was still in pain, so he couldn't catch it, and in the end, he could only apologize for letting Lao Tan fall heavily to the ground.

Lao Tan's injuries were much more serious than Mu Yu's, and he didn't have a piece of good meat on his body, and it was covered with the claw marks of various demon beasts. He was dripping with blood in many parts of his body, his chest was blurred with blood, and there were several scratches on his face, and he had fallen into a coma at this time.

Mu Yu hurriedly injected spiritual power into Lao Tan to help him heal. When he wanted to use Lao Tan just now, he accidentally touched the broken hand again, and now he began to feel a dull pain again, and the skin on his back and legs was also open, and he borrowed a little bit of the vitality of the aquatic plants last night to heal himself, and it was already much better, and then all the vitality of the aquatic plants was input into Lao Tan's body.

"Xiao Shuai, quickly mobilize your aura!" Mu Yu said.

"The aura is too thin here, but you can still give it a try. Xiao Shuai began to dance its big tail, so that the surrounding aura was thick, Mu Yu hurriedly and desperately absorbed these aura, his arm hurt all night, and finally felt better.

I don't know how many hours passed, Lao Tan finally opened his eyes, after all, he was a cultivator in the Yuan Infant Stage, and coupled with Xiao Shuai's regulation of spiritual power, his recovery ability was still very strong.

"Did you figure it out?" asked Old Tan as he struggled to sit up.

Mu Yu nodded, and Lao Tan barely squeezed out a smile, this injury was not in vain. Mu Yu asked Lao Tan to sit and rest, he was going to find the mark he made last night, and pick up the Dan flint by the way. Mu Yu didn't know what kind of demon beast he killed last night, Mu Yu searched all over the surroundings and there was only a pool of blood, thinking that the big demon beast should have been divided by the demon beast, he was a little regretful, he originally wanted to see what the hell his big-eyed demon beast was.

In the end, Mu Yu found the location where he made the mark yesterday, and the mark made with the bone had been trampled by the demon beast, but fortunately, Mu Yu also made a mark on the cliff wall, and Mu Yu drew a line on the river bank through the mark on the cliff wall.

"Is this the tipping line we ventured to identify?" Old Tan walked over and carefully examined both sides of the line, and there was nothing out of the ordinary.

Mu Yu nodded, any formation has a boundary, and the general method of cracking the maze is at the critical line. Mu Yu carefully observed the line on the cliff wall, and finally found something strange in one place.

There is a small engraving on the cliff wall next to the wooden feather marking, which is not visible without looking closely, and this engraving is painted with the same color as the cliff wall. Mu Yu knew this pigment, which was a material specially used for carving arrays.

Many formations are directly depicted with spiritual power, but this is too spiritually intensive. There is a special material ground into powder, which can be used as a spiritual power engraving line to depict the formation pattern, and Mu Yu saw it when he was looking for the old man in the array.

Xiao Shuai compares this formation to two mirrors, one mirror at each end of a straight line, a mirror on this side, and a mirror on the other side, and when the mirror enters from this side, it will come out from the mirror on the other side, which is why Mu Yu went to the end and returned to the starting point.

The scope of this mirror is very large, and it actually spans this valley, but fortunately, the distance between the two mirrors is not large, which shows that the formation is limited.

Mu Yu didn't have a way to break the formation, he wanted to destroy this carving, but the cultivation of the people who arranged the formation was higher than him, and he didn't have the ability to destroy the carving, and even Lao Tan didn't have that strength.

"So even if we find the critical line, it's useless?" Old Tan's face darkened, he couldn't accept it after working so hard for so long to get such a result.

Mu Yu stood on the carving, took a few steps back, looked around, looked up at the cliff, and his eyes lit up: "It's not impossible." ”
