These inks are the traces of the formation hub.

Mo Hua's eyes are slightly bright.

He guessed correctly.

Just like when he built the Five Elements Demon Slaying Formation, since he needs to use the formation pivot to control all individual formations, the ink "trunk" of the formation pivot must connect the inner hall and the outer hall.

At the same time, these array hubs must be hidden inside the building and cannot be exposed.

To avoid being targeted by "careful people" like myself.

But no matter how hard I hide it, I still can’t hide it from my clever self...

Mo Hua nodded proudly.

Next, we just need to follow the vine and find the central control of the complex formation through the "vine" of the formation hub...

The problem is...

Mo Hua looked at the entrance of the cave, turned around and said to Gu Changhuai and the others: "You are too tall, it seems you can't get in..."

Gu Changhuai, the three of them had complicated expressions.

They can't deliberately grow shorter just to drill this hole...

Mo Hua sighed, "There is nothing I can do, let me go in and take a look..."

Gu Changhuai frowned, "Are you going alone?"

"It's okay," Mo Hua said, "This is the place where the formation pivot is hidden. I'm very familiar with it, so there won't be any danger..."

The formation hub must be kept secret.

Not only cannot outsiders know about it, but even our own people are prohibited from approaching.

The buildings near the formation hub will only have some early warning and protection measures when constructing the formation.

But these measures are not worth mentioning in the eyes of Mo Hua, who has built a large array.

Gu Changhuai said thoughtfully: "You can take Bone Shrinking Pill to shrink your body in a short time..."

"Shrinking Bone Pill?" Mo Hua was startled.

Is there such a thing?

There are so many strange things in the monastic world.

Mo Hua thought for a while, then shook his head and said:

"Shrinking your bones doesn't work either. The flow of spiritual power in the formation hub is chaotic and can easily radiate to the spiritual weapon, causing the formation on the spiritual weapon to become confused and ineffective..."

Mo Hua pointed at the jade pendant on Gu Changhuai's body, "I'm afraid the water hidden jade will be affected and unable to hide..."

Gu Changhuai's eyes darkened slightly.

He didn't expect this...

After all, he is not an array master and does not have a deep understanding of such subtle array principles.

"wrong……"

Gu Changhuai suddenly realized, "Our Water Hidden Jade has failed and cannot become invisible. Isn't yours the same?"

"I'm different." Mo Hua said, "I know the art of concealment."

Gu Changhuai opened his mouth and lost his voice:

"When did you learn the art of invisibility?"

Mo Hua looked innocent, "I always know how to do it..."

Always will...

Gu Changhuai looked deceived and was speechless.

"You never asked me..."

Mo Hua muttered.

Uncle Gu didn't ask about things like concealment. There was definitely no need for him to tell him...

Gu Changhuai took a deep breath and glanced at Mo Hua, "Then I gave you Shuiyin Jade, why did you just accept it?"

"There's a lot more emphasis here..."

Mo Hua plausibly said: "According to my research, concealment spiritual weapons and concealment spells, when used at the same time, can have a double concealment effect, and the concealment effect is better..."

"The Devil's Cave is so dangerous. I, a young foundation-building monk, am walking on thin ice. Naturally, the more careful the means to save my life, the better..."

Gu Changhuai felt for a moment that what Mo Hua said made sense...

It's just that along the way, Mo Hua walked briskly, and he couldn't tell where he was "walking on thin ice"...

Gu Changhuai sighed.

There are bursts of yin energy and green light all around.

Under the stone corridor, there is thick and smelly rotten water flowing...

Being in the Demon Palace is not the time to worry about such things.

Moreover, no matter how precious a hidden spiritual weapon is, it is indeed not as dangerous as the ink painting.

Gu Changhuai sighed: "Okay, just be careful..."

He thought for a while and added:

"After entering, if you are in danger, shout for help and I will find a way to rescue you..."

Mo Hua was a little surprised, nodded and said:

"Don't worry, Uncle Gu."

Now that he has found the formation hub, the danger in this devil's cave has become a little smaller.

Then Mo Hua was alone, ducking into the array pivot passage behind the wall, using his hands and feet together, following the veins of the array pivot, and slowly crawling towards the core of the Yuan Magnetic Array.

The stone path is narrow and narrow, and the terrain is sometimes gentle and sometimes vertical and steep.

It is also engraved with the pivot of the Yuan Magnetic Formation and some early warning formations.

Mo Hua avoids these formations, and at the same time uses the passing water step, attaching spiritual power to his hands and feet, using his spiritual consciousness to pull him close to the wall, like a "little gecko", slowly advancing in the formation hub channel.

The magnetic current I sensed before was just a weak water flow.

So now the formation hub is like a surging river.

The flow of spiritual power is very clear.

Even with his eyes closed, Mo Hua knew where to go.

Following the flow of spiritual magnetism in the center of the formation, he walked forward like a gecko painted in ink. After walking for an unknown amount of time, he reached the end of the passage.

The passage is dark and the formations cannot be seen.

But Mo Hua can perceive with his spiritual consciousness that the flow of Yuanqi converges at the front end, and then coordinates downwards, controlled by a central controller.

The center of this complex formation is the main formation hub similar to a large formation, which controls the entire Yuan Magnetic Complex Array!

Found it!

Mo Hua felt happy.

There is a little halo at the end.

Mo Hua used his hands and feet to climb to the end, stuck his little head out, and looked down through the gaps in the building.

As expected, there is indeed a secret room down there with the central control center painted on it.

In the secret room, there are dense formations.

There is a unified formation plate in the middle, with the core formation pivot painted on the formation plate.

Mo Hua held his breath and used the Five Elements Concealment Technique to the extreme, then opened a pair of big watery eyes and peered down from the gap.

He saw that there was another person in the secret room.

This man was thin and tall, wearing an elegant and luxurious Xuan robe. His face was deathly pale, his eyes were bloodshot, and his face had deep nasolabial folds.

Like and similar.

As a formation master, Mo Hua could tell at a glance that this person was a superb formation master, and his aura was not correct, and his hands were stained with blood that could not be washed away.

He is an evil formation master.

Second-grade high-level evil formation master!

Mo Hua felt a little chilled in his heart.

The evil formation master was currently sitting in the secret room, drawing a bloody formation. After a while, he raised his head and looked at the master control array in front of him, monitoring the movements in the Demon Palace.

Occasionally he would pick up the wine glass and take a sip of wine.

The wine was dark red, with a strange eye in it.

That eye would blink occasionally.
