There is no doubt that this is an advanced formation.

People who have not studied the formation in depth will not be able to see through it at all, let alone open it.

The underground space where the "Jewel Dragon" stayed now seems to have been artificially opened up.

In order to lay out the formation and build a palace or cave.

As for whether there were people in the palace or cave, it is impossible to be sure.

Judging by the traces on the stele, there may be no one, because the surface of the stele has corroded, which is obviously caused by too much time.

The three-color glow at the beginning just now was not that the stone tablet was stimulated by anything, but that the surface was corroded and a lot of debris fell off, which caused the formation to be touched, and then cast light.

Based on this deduction, the six coiling dragon pillars, the square patterns on the stone walls, and the formation gates are all influenced by the stone stele, or have a great relationship with the stone stele.

This is easy to verify.

Tang Mubai took out the skin of the corpse of the Golden Flame Demon Insect and covered the stone tablet all over the top.

"Boom~"

The ground and the dome trembled, first the swimming array gate disappeared, all the formations stopped moving, then the patterns on the stone wall disappeared, and then the six coiling dragon pillars, in a series of "rumbling" sounds, retracted back to the ground or the dome.

In less than ten seconds, all the spectacular scenes disappeared, and the underground space returned to its original appearance.

The "Jewel Dragon", who came back to his senses, looked at the stone tablet blankly, and then looked at Tang Mubai.

Tang Mubai removed the skin of the corpse of the Golden Flame Demon Insect-

"Boom~"Boom~~""Boom~~~"

The six coiling dragon pillars are re-protruding from the ground and the dome, arranged at the same distance.

The patterns on the stone wall and the gate with the pattern of the formation appear in turn.

The whole process was the same as before, fast and neat.

Cover the skin of the corpse of the Golden Flame Demon Worm back on the stone tablet.

"Boom~"

The dragon pillars, patterns, and gates disappeared again.

The trial was successful!

The stele is indeed the key.

The skin of the corpse of the Golden Flame Demon Insect itself has the effect of covering and blocking the breath or edge.

Tang Mubai thought of it in his heart just now, took it out and covered it, and the stele was immediately hit!

That's where the fun begins.

"Has this stone suddenly glowed before? and many times?"

Tang Mubai looked at the "Jewel Dragon" for the final verification.

"Whew!"

The "Jewel Dragon" nodded, indicating that it was right.

"That's right. Tang Mubai clapped his hands and said excitedly.

To open the formation, it is necessary to inject qi and blood into the stone tablet, and it is unknown how long the 999 calories of qi and blood can last.

The automatic glow of the stele is caused by a lot of corrosion and detachment on its surface.

In this case, as long as the stone tablet is covered, the formation can no longer be opened.

The palace or cave of the strong behind the stone wall is unknown to anyone.

Tang Mubai can't crack the formation now, he has to learn it when he goes back, and then he will crack it.

Before that, he had to keep the palace or cave of the strong behind the stone wall.

It's a coincidence!

A big opportunity for Tang Mubai!

With manpower to open up such a large underground space, leaving such a complex formation to protect, the palace or cave of the strong behind the stone wall, there is a nine-in-a-nine chance that there will be treasures!

"Sacred Heart" also senses good luck.

For this reason, the treasures inside cannot be taken by others.

It's just the skin of the corpse of the Golden Flame Demon Insect, and you can use it casually.

There is also the "Jewel Dragon", which cannot be treated badly.

If he hadn't chased it in, Tang Mubai would have encountered such a big opportunity.

"Pak~"

Take out the corpses of ten fire-eating beasts at once and throw them in front of the "Jewel Dragon".

Tang Mubai grinned, "Thank you for taking care of you, these fire-eating beast meat has been given to you." ”

“......”

The "Jewel Dragon" didn't respond, he looked at the fire-eating beast meat, and then looked at Tang Mubai with a strange gaze.

Tang Mubai didn't care either, patted the skin of the corpse of the Golden Flame Demon Insect covering the stone tablet, and discussed, "These insect skins, I hope you don't move...... By the way, you shouldn't eat the skin of giant worms, right?"

Thinking of something, Tang Mubai stared at the "Jewel Dragon" without blinking.

"Whew!"

The Jewel Dragon roared, his eyes filled with disdain and annoyance.

It seems that Tang Mubai insulted it.

There were giant worm-eating dinosaurs, but it was never included.

Because giant worms have no blood, only pulp.

Most dinosaurs and fierce beasts don't eat giant insect meat, and the reason is here.

"It's good not to eat. ”

Tang Mubai chuckled, "Don't move the insect skin, I'll come back next time and bring you something delicious." ”

"Jewel Dragon", "......"

Nima, still coming?

The "Jewel Dragon" was speechless. It's a pity that he can't speak, and he can't scold people if he wants to, so he can only close his eyes again and be too lazy to look at Tang Mubai.

In this regard, Tang Mubai smiled and connected the skin of the corpse of the Golden Flame Demon Insect in turn, covering every corner of the stone tablet.

After it was done, I told him again before leaving the underground space and returning the same way.

Go back to the surface and place the vines.

Just about to take off into the sky and fly into the sky -

"Boom~!"

A thunderous sound, suddenly sounded.

Before Tang Mubai could sense the crisis, a four-meter-diameter Taiji fish pattern emerged from behind, blocking the sudden attack.

"Tai Chi Xuangong" automatic defense!

And the person who attacked the sneak attack looked at this scene in a daze, his eyes widened, and his face was full of astonishment.

"Fire Dragon Thorn, Chen Mukui, Grand Master Chen, what kind of grudge do I have with you, so I drove you to use the Fire Dragon Thorn to kill me?"

Tang Mubai turned around and looked at Chen Mukui, who was hiding in a bush, holding the "Fire Dragon Thorn" cylinder container after the launch, and said coldly.

This kind of thing is a fire dragon thorn, although it is a one-time treasure, but it can bombard the grandmaster!

If it weren't for the automatic defense of "Tai Chi Xuangong" just now, although Tang Mubai would not have died, he would inevitably be injured.

As for why the "Sacred Heart" did not sense the crisis in advance, there is only one explanation.

The target of Chen Mukui's assassination was not him.

In other words, anyone who comes out of the hole in the earth is his target!

No matter who it is, as long as he sees someone, he will attack, kill first!

The purpose is simple, capture the gems!

Unfortunately, the operation failed.

At this moment, facing Tang Mubai's cold gaze, Chen Mukui felt like falling into an ice cave, his heart was beating like a drum, and his whole body was stiff.

With a strange scream, Chen Mukui threw away the useless cylinder container, turned around and ran.

"Want to run?"

Tang Mubai drank coldly, and did not rush to catch up, but waited for Chen Mukui to run out more than 100 meters and was about to disappear, before he performed "Star Picker", targeted Chen Mukui, suppressed it in the air, tied it up, and finally grabbed it back.

"No, no, no!"

Chen Mukui screamed in panic and struggled desperately, but it was useless.

Seeing that he was imprisoned by an invisible force, he couldn't move, and flew towards Tang Mubai from the air.

"Don ...... Grandmaster Tang, I'm ...... I was wrong, I didn't know it was you, really, I didn't want to kill you, it was a misunderstanding, it was really just a misunderstanding!"

Chen Mukui's voice trembled, trembling and shouting.

"Misunderstanding?"

Tang Mubai squinted, "You attacked me with the 'Fire Dragon Thorn', just a misunderstanding?"

"Yes...... yes, it's really just a misunderstanding!"

Chen Mukui answered in a trembling voice, and at the same time, his brain spun rapidly, and blurted out, "Sect Master Tang, as long as you let me go, I will tell you a secret, the secret of the 'Tianxing Group'!"
