Li Mu came to the next room suspiciously, and as soon as he opened the door, a white bone squeezed out of the narrow crack in the door......! A bone of a human arm!

Li Mu swallowed his saliva, and he cautiously walked into the room. The room was empty, only bones strewn across the floor. At a cursory glance, there are at least dozens of them!

He felt his scalp tingle a little, and grinned back to the room just now, "What the hell is this place!?"

"Once upon a time, this was the prison of the Demon Cult. ”

"Demon Sect Prison?" Li Mu blinked: "What about now?"

"Now...... This is the abandoned prison of the Demon Cult. ”

Li Mu twitched the corners of his mouth and sat down opposite the three old men: "This joke is not funny at all!" Just after he sat down, the three old men got up at the same time, ignored him, and walked out of the room!

When he reacted and chased out, there was not even a ghost in the dim corridor!

Wait a minute!

There is a figure......

It was the old man who brought him to this room!

His voice was still so gentle: "This is the blade that you need to imitate." Little one, do you want to see if it's difficult?"

Li Mu took this blade, and by the light coming from the room, he could clearly see that it was a short knife. The key thing is that underneath the handle of the short-edged blade, there is a black skull dragon head like jade!

This is a skull faucet that is exactly the same as the skull faucet in Xiao Lang's hand!

"Oh, sorry. The old man seemed to smile, and his hand was on the handle of the short blade in Li Mu's hand. Break it gently. Click. The skull broke away from the short blade in response!

Li Mu looked at the old man blankly: "Uncle, what is this?"

The old man put the skull in his arms: "This is the 'dragon chant'! Okay, little one, from now on, you may have to work harder, copy this short blade as soon as possible, okay?"

"Okay, but can I get out of here after I have copied this dastard?"

"Of course!" the old man smiled and turned away.

Li Mu settled down. He checked the Black Consciousness Sea, and fortunately, the breathing method was not affected in this place, at least, he was still a body art flow of the Great Saint Realm!

Gathering his thoughts, he locked himself in a room. This room was directly opposite the room where the three old men were eating just now, and he wanted to see if it was just like what the three old men said, they only ate one meal a year!

The following days were boring, and Li Mu locked himself in his room every day. There's plenty of Mithril here. There are all kinds of materials, and he is fully focused. Entered the realm of a selfless drawing formation......

There are a total of three formations on this short blade, and Li Mu can determine through the comparison of the hundred array diagrams that the three formations on this short blade are: King Kong Array, Flowing Water Array and Liberation Dragon Array.

The five elements of the Vajra Array belong to gold, which mainly increases the hardness of the blade.

The five elements of the flowing water array belong to water, which mainly increases the toughness of the blade.

The release dragon array is much more complicated, its five elements belong to fire, and different fire attributes can improve the different needs of the formation. For example, this Liberation Dragon Array, it is not an independent formation, but a formation that continues between the Vajra Array and the Flowing Water Array.

To put it bluntly, the role it plays is very similar to Li Mu's cultivation of Dou Zhuan Xing Shift, and its main function is to balance the two extreme formations of hardness and toughness!

Other than that......

In addition to the function of balancing, the Dragon Liberation Array also has extremely strong lethality!

According to the record of the Hundred Arrays, the Dragon Liberation Array requires the sevenfold cultivation of the Great Sage Realm to draw it!

Li Mu patted his head: "Headache!" He sighed, prepared all the materials he needed, and began to try to imitate this formation......

"No! you shouldn't have drawn the Vajra Circle ...... first."

"That's not right, if you draw the flowing water array first, the release dragon array won't be added......"

"It's still not right! The release of the dragon array is to play the role of threading and bridging, if you don't draw the diamond array and the flowing water array first, where will this release dragon array go?"

At sunrise and sunset, Li Mu locked himself in the room for three days and never walked out of the door for half a step!

"No! No! Not at all!" Li Mu threw out the Mithril in his hand irritably, sat on the ground one by one, closed his eyes, and continued to think about the key to these three formations.

Suddenly, a series of dull footsteps sounded on the corridor outside the door, and this sudden change made Li Mu immediately interested. He knew that there were only him and the three imprisoned old men on the entire third floor, and as for whether the old man who gave him the blade lived in the third floor, Li Mu was not sure. But one thing is for sure, and that is that this footstep sound is definitely not from them!

This voice sounded dull and powerful, obviously coming from a tall and fat guy, and this guy didn't know how to light up martial arts!

Thinking about it, Li Mu had already gotten up and came to the door, gently opened the locked door, opened a gap and looked out...... The cloister was still so dark that only a little light could be seen through the crack in the door.

Moreover, the footsteps just now are gone!

"What's the situation?" Li Mu came out of the room, his right palm was held up, and a light cluster formed by the power of the law condensed in the palm of his hand, illuminating the nearby places.

He prepares to check room by room!

When I opened the door of one room, as the old woman said before, there were materials for drawing formations such as Mithril in each room, but there was no one living in it.

2nd room, 3rd room......

Li Mu inspected room by room, and in the end, he suddenly found that he didn't see the three old people who had eaten before!!

He is the only one on the entire three floors of the castle!

"Isn't this the hell!?" Li Mu muttered, turned around and went into a room, lighting all the candles in the room!

After thinking about it, he took the extra candle to the cloister and lit it again!

Then it's the next room!

In a short time, he lit all the candles on the third floor of the entire castle, and illuminated the place!

Li Mu's gaze froze, and he seemed to have overlooked an important question: What is in the middle of the corridor?

There are all rooms on both sides of the corridor, but Li Mu has calculated, according to the area of the third floor, there is still a large area that he did not see!

This area is located in the middle of the third floor!

"Little one, what are you doing?"

Li Mu turned around, and the old man who gave him the blade was standing at the corner of the corridor. Li Mu said honestly: "Old man, I heard footsteps in the corridor just now. ”

A smile hung on the old man's lips: "Everyone has his secrets, and so does the master here. No one wants their secrets to be discovered, do they?"

The old man paused, and he suddenly laughed: "Little guy, there is no pollen from the purple gold fragrant flower in the meal I brought to you, you can eat it with confidence." Besides, you're not a prisoner here, and I'll naturally send you out of here when the seven days are up, so there's nothing to worry about. (To be continued.) )
