Yi Fan smirked and stuffed the black gem into his pocket. He patted the bag, with only four words written on his face, satisfied.

Li Mu said at the right time: "Let's go, let's go back." ”

"Good, good. Yi Fan is now the time to be happy, and he agreed.

This is a dead end, there is no way ahead, and the four of them can only return the same way. The four of them returned to the original intersection, and as they walked, Li Mu suddenly stopped.

"Wait a minute. Li Mu stopped everyone. "Something is wrong here. ”

"What's wrong?" asked Shen Li.

Li Mu raised his hand and pointed to the wall at the entrance. "The markings here are gone. After Li Mu confirmed that this was a labyrinth, he wanted to carve handwriting at the intersection to explore the way. It's actually a way to determine where you are when you're lost.

Because the walls don't move. Therefore, you can determine your position by marking it.

But what made Li Mu feel strange was that he had carved the arrow mark on the wall with his own hands just now, as well as the number of intersections they encountered, but when he returned, this mark was gone.

Li Mu took a closer look at it with a firefly bead and found that there should be a mark, and there was no nick at all. With Li Mu's height, the height at which he raised his sword and engraved it was probably at the position of his head. This position, he will not be mistaken.

"How could it be gone?" Li Mu muttered to himself.

Leng Zizhou also noticed something abnormal, and he frowned, "This can't be." ”

Li Mu squatted down and touched a handful of moss on the ground with his hand, "It's still possible." We thought the mark would be foolproof if it was engraved on the wall, but that was when the wall wouldn't move. What if the walls here move?"

"The wall moves? What are you kidding? Yi Fan said with some surprise.

Li Mu pointed to the corner of the wall, where the moss was torn, and there was a very conspicuous mark between the moss on the wall and the moss on the ground. "If the wall doesn't move, it won't be like this. ”

"But why don't we feel it at all?" asked Shen Li. Yi Fan echoed: "Indeed, I didn't feel it at all just now. As he spoke, something suddenly occurred to him. He patted his head and exclaimed, "Damn, it's those black gems!"

Li Mu sometimes has to admit that Yi Fan's thinking is also very agile when there is no money in front of him. He nodded and said, "That's right, because the temptation of gems is in front of us, and it takes most of our attention. After thinking about it, Li Mu added, "Plus we have to watch out for the organs, so it is even more difficult for us to notice other movements." ”

"In other words, our way has changed?" Shen Li looked at the road he came from, a little worried.

"It's a problem. Yi Fan also calmed down, their situation is not very good now. "If the walls move and the passages change, then it's not going to be useful for us to make markers. ”

"In other words, is it very likely that we will be trapped here?" Shen Li said weakly.

Leng Zizhou added, "It's very likely." ”

Shen Li, Yi Fan, "......"

Li Mu saw that the crowd was a little depressed, and said, "Fortunately, we know this. If it weren't for the moss in the corner, it would have been a long time before we figured it out. If so, we may have been lost in the labyrinth. Now that we know that the walls change, we can be prepared. ”

"Precautions, how to prepare?" Yi Fan's face was not very good-looking, "Even if we know that he will move, but I don't know how it moves, we still have to be trapped here." ”

Li Mu thought for a while and asked very seriously, "Yi Fan, do you remember the boat formation we broke into on Mirror Lake?"

"That......" Of course Yi Fan remembered what happened to him and Li Mu in Jinghu, after all, it was still a shocking thing for so many big ships to be connected into a whole with iron locks.

Li Mu smiled at him: "At that time, I just watched underwater for a long time before I saw the flaws in the ship formation. With that, he began to draw his sword.

Hearing Li Mu say this, and watching him draw his sword again, Yi Fan's voice shook, "Hey, don't you want to..." Before he finished speaking, Li Mu plunged his sword into the ground. Gather energy in the sword. With the sharpness of the Thunder Sword and Li Mu's true qi, it was easy to do this. But that wasn't the end of it, he gripped the hilt of his sword and swiped hard.

As Li Mu cut hard, Li Mu tore a hole in the corner of the wall. Through this opening, Li Mu saw the bronze gears and other parts buried in the wall. It seems that the dampness outside the corner of the wall has not affected the inside of the mechanism, and there is no rust on the parts.

Seeing what's inside the wall, all four of them took a breath.

"Who is buried in this tomb, and who made it, and can make such a sophisticated mechanism?" Yi Fan asked again and again.

Li Mu looked at those organs and replied, "I can answer the first question." This burial place should be a person who saved the witch clan and was admired by everyone... Immortals..."

"Are there really immortals in the world?" Yi Fan felt a little unconvinced.

"I don't know, that's what was recorded on his coffin anyway. Li Mu inserted his sword into the breach and cut off one of the parts. "Anyway, no matter how delicate the mechanism is, if you don't let it work, there's nothing going on?"

"It makes sense, it's your style. However, is your sword too sharp?" Yi Fan saw that the sword in Li Mu's hand easily cut the bronze parts, so he paid attention to the sword in Li Mu's hand.

Li Mu didn't hide it, and told them the process of getting this thunder sword. Leng Zizhou's eyes were also a little envious when he looked at the thunder sword. After all, they are all people who practice martial arts, and the pursuit of weapons is also part of the pursuit of force. When I saw a good blade, I couldn't help but be envious. However, it is only envy. After all, he himself uses a gun, and although the sword is good, it is not his favorite.

Yi Fan was different, he directly snatched Li Mu's Thunder Sword, tried it a few times himself, and exclaimed: "It's really a good sword." No wonder you don't care about the rest of your treasures. ”

Yi Fan is a person who points at people with a sword, and he knows better than Li Mu the meaning of a good sword for a swordsman. Although many kendo seniors have said that the strength of a swordsman still depends on his own strength. A person with lame swordsmanship, with a divine weapon, still can't get on the table. And a swordsman with superb swordsmanship is also amazingly powerful with a woodcutter.

But if you really want to talk about it, if you ask a kendo master, whether he likes to use a woodcutter or a magic weapon, ninety percent of the masters will choose the latter.

After all, there is an old saying that if you want to do a good job, you must first sharpen your tools. On the contrary, having a favorable weapon in hand is definitely twice the result with half the effort.

Shen Li's focus was different from theirs, and her gaze fell on the sword that Li Mu had given her. This sword is exactly the same as Li Mu's Thunder Sword, and it can be regarded as a pair of swords. She heard him raise his sword, and his name was Thunder. So she naturally remembered that sultry afternoon in Yacheng, in the courtyard of Fruit Tree Street.

"I'll call you the Thunder Sword. Shen Li remembered the name he had given to the sword he had taken from Li Mu. Thunder and thunder, just a pair.

At this moment, a "quack" suddenly came from a distance. Li Mu was shocked, he turned his head to Yi Fan and said, "Did you hear it?" "I heard it, it seems to be a frog barking." Yi Fan didn't care.

But not long after, Li Mu suddenly heard a vibration on the ground. And in the midst of this vibration, a frog chirped closer and closer.

Li Mu tilted his ears to identify the direction, he walked out of the passage and looked towards the fork in the road. The sound came from that direction. Listening to this momentum, it seems that something big is approaching.

Li Mu picked up the firefly beads and threw them out along the passage.

The fireflies rolled on the ground, and soon bumped into something and stopped. Then the light brightened, and Li Mu saw clearly what the thing that was close was.

It wasn't a thing at all, it was a living thing, it was a huge, weird frog.

It was massive, filling almost the entire passage, with two raised horns on its head, and on its neck there seemed to be a strange vine entwined around it, producing a trumpet-like flower.
