"Let me study it!"

The spirit crab responded in his heart.

Immediately afterwards, the spirit crab spit out a bubble, and in the bubble, there were some small black crabs.

The bubble landed on these formations and then shattered.

The little black crab instantly became transparent and then hidden.

None of the demon cultivators in this layer of space were discovered.

These little crabs spit out some tiny bubbles, which fall on these patterns and then slowly penetrate into them.

An hour later, the voice of the spirit crab echoed in Ling Feng's mind, saying: "Ling Feng, this formation pattern is very strong. It is difficult to destroy without using empty thunder beads. After my research, there is a twist.

This method can destroy this array pattern with just one empty thunder bead!"

"One?"

Ling Feng's eyes condensed. He now had three empty thunder beads on hand. If he used one, he would still have two left.

As for the remaining two empty thunder beads, Ling Feng has no intention of dividing them with Qin Ze and Baili Changfeng.

Because if they complete this mission and return, Baili Changfeng and Qin Ze will also receive corresponding military exploits, and the military exploits will be very high.

"Then do as you say!"

Ling Feng responded in his heart.

Ling Crab and Ling Feng sent a message: "There are so many demons now, and it is inconvenient for us to move. Their teleportation array will not keep running. We can only take action after their teleportation array stops functioning!"

"Then let's wait!"

Ling Feng responded, and then stayed on the second negative floor of the tower.

In this way, they waited for three days before the tower was closed.

When the tower was closed, the demon tattoo masters immediately entered the tower and checked the teleportation array.

Because some problems may arise during the operation of the teleportation array, so it will be stopped and checked every time it operates for a period of time.

"When are we going to do it?"

Ling Feng asked Ling Crab in his heart.

"Don't worry, we'll wait until these tattooists finish their inspection before we start!"

The spirit crab's voice echoed in Ling Feng's mind.

As for Qin Ze and Baili Changfeng, they were almost going crazy inside Ling Crab's body. Under such circumstances, every moment was torture for them.

Three hours later, the tattoo masters completed their inspection and left.

After they left, the door was sealed with a seal.

The tattoo master of the demon tribe put his soul mark on the seal of the gate, because they completed the inspection this time, and if there is any problem with the pattern, the superiors will question them.

"It's time to move!"

After these demon tattoo masters left, Ling Crab spoke to Ling Feng.

Ling Feng immediately followed the method described by Ling Crab and embedded an empty thunder bead on a formation pattern.

"Is it that simple?"

Lingfeng asked Ling Crab in his heart.

"Yes, it's that simple. This place is the biggest flaw of this teleportation array. When they use this teleportation array tomorrow, the power of the space law will activate the empty thunder beads! At that time, the empty thunder beads will be activated.

It will explode and form a series of chain reactions. The powerful space collapse force will swallow up the entire tower and even all the people in this stronghold!"

The spirit crab's voice was a little excited.

"so smart?"

Ling Feng was stunned for a moment. He now suspected that Ling Crab was bragging.

"Of course, not everyone can find this array of eyes. Even the demon masters just now didn't know about it. Even those who set up the teleportation array didn't know that there was such a thing in their array.

A flaw!"

Ling Crab said confidently.

"good!"

Hearing Ling Crab speak so confidently, Ling Feng nodded and waited quietly.

Because the tower has been sealed, even if Lingfeng has the ability to unlock the restrictions, he cannot dig holes in these walls made of a single piece of red stone without anyone noticing.

"what you do?

Don’t want to leave?”

The spirit crab saw Ling Feng sitting down on the ground and immediately sent a message to Ling Feng.

“Wait until they open tomorrow!

"Ling Feng responded in his heart.

"What the hell, wait, we have to leave now. When they open the door tomorrow, they might activate the formation immediately. By then, the formation will collapse and we won't have time to escape!"

Ling Crab opened his mouth and cursed Ling Feng.

Ling Feng glanced around, and then said: "Now that this space is sealed, how can we get out?

Chiseling the wall?”

"Of course we cut the wall!"

The spirit crab responded.

"Are you sure we won't alert them by cutting the wall?"

Ling Feng asked in his heart.

"Do not worry!"

The spirit crab responded and took Ling Feng back into its body. Then it crawled to an inconspicuous corner and began to spit out bubbles. A small golden crab appeared and began to eat the stones.

After burning the incense, the golden crab dug a small hole in the stone wall, and the spirit crab took Ling Feng and left the stone building.

"It finally came out, but won't they find the small hole you made?"

Lingfeng asked Lingxi.

"No, that little crab will seal the hole!"

The spirit crab responded, then led Ling Feng towards the exit of Demon Clan Stronghold No. 39.

Although it is night now, the exit of the Demon Clan's No. 39 Stronghold is brightly lit, and people are coming in and out one after another.

The spirit crab restrained its breath, led Ling Feng and the others to quietly approach the exit, and then left through the exit.

Demon Clan Stronghold No. 39 strictly checks people who come in from the outside, but it is not so strict with people who go out.

Therefore, the spirit crab can easily take Lingfeng and the others away.

After leaving Demon Clan Stronghold No. 39, Ling Feng and the others found a place where the spirit crabs released Baili Changfeng and Qin Ze.

"Lingfeng, have we completed our mission?"

Baili Changfeng asked Lingfeng.

Ling Feng shook his head slightly and said, "Not yet, let's wait until daybreak. We'll see what happens then!"

Baili Changfeng and Qin Ze nodded, and then together with Ling Feng, they waited outside Demon Clan No. 39 Stronghold for dawn.

"Let's go a little further!"

Ling Crab opened his mouth and said to Ling Feng.

At this moment, Ling Feng and the others were less than ten miles away from Demon Clan Stronghold No. 39.

"Not far enough?"

Ling Feng asked Ling Crab. Ling Feng felt that this distance should be far enough.

"That's right. Even if the space teleportation formation in the tower causes space collapse, the area of ​​impact won't be so large, right?"

Baili Changfeng spoke to the spirit crab.

"For safety's sake, stay at least twenty miles away!"

The spirit crab spoke.

"All right!"

Ling Feng responded, then led Baili Changfeng and Qin Ze to retreat twenty miles away from Demon Clan Stronghold No. 39.
Chapter completed!
