Tan Chu took the three of them and walked quickly to the foot of the mountain, looking at the middle of more than a dozen caves, the largest cave entrance.

Inside this cave, about ten meters or so, a red light loomed, startling his heart.

He understands that this is what those NPCs call the Sealing Enchantment, but he doesn't know how powerful it is?

"Lord Beast, this is Elder Hongye's private cave here, some of us have been in the Shadow Moon Canyon for more than a hundred years, but we have never entered and seen it, so we don't know what is going on inside." Pegasus Rainbow said.

"Then you know that Shentie is inside?" Tan Chu asked suspiciously.

"I know, the Divine Iron was personally put in by Elder Hongye, mainly as a source of divine power to maintain the seal, and it shouldn't be a big problem for you to take a piece." Rainbow Shadow replied.

"Isn't it, there's more than one piece of divine iron?" Tan Chu was surprised.

"As long as the beast-sama can get in, he'll understand." Pegasus Rainbow said.

"Little brother, I'll help you open the seal." Hei Jiao couldn't wait to say.

"Well, it seems that you have to rely on you to open the seal." Tan Chu said with a smile.

The Black Jiaohua Dragon advanced, unexpectedly became a thunder dragon, and had the special ability to break the seal, which was indeed a strong assistant for him.

He asked Heijiao to step forward, and he took the two Pegasi with him, and then walked into the red grotto.

The wide cave has neat and smooth stone walls on both sides, and it looks like it has been dug by hand.

Just ten meters from the entrance of the cave, a raging fire curtain in the middle of the cave covered the entire cave entrance tightly.

Looking at this wall of fire, it seemed to be the seal that the NPCs were talking about, Tan Chu stood there, waiting for Heijiao to make a move.

I saw the silver-armored warrior holding a double hammer and striding in front of the wall of fire, his whole body emitting blue thunder and lightning entanglement.

Bang!

With a thunderous sound, the black Jiao smashed the two hammers together, and the blue thunder shot straight out.

With a bang, the thunder pillar hit the wall of fire hard, and the flames scattered and separated, and a circular hole appeared in the middle of the wall of fire.

"Ahh The. This is actually a thunder dragon?" Whimsical exclaimed.

"It's so strange, when did the dragon clan appear thunder dragon god?" Tianma Hongying also opened her beautiful eyes and looked at Heijiao in surprise.

"He's a miracle." Tan Chu laughed.

"Little brother, let's hurry in, my ability can only break the seal temporarily, but it won't last long, it will soon return to its original state." Hei Jiao looked back and said.

"Got it, let's go inside." Tan Chu nodded, and led the three of them forward quickly.

The scorching temperature came to their faces, and the three of them drilled through the fire hole in front of Hei Jiao and easily entered the cave.

The black Jiao immediately followed, the flames flickering, and the wall of fire returned to its original state.

"The guy who set up this enchantment must be very strong, my thunder divine power can only temporarily force the seal back for so long..."Hei Jiao looked behind him and said in surprise.

"In your opinion, who in the dragon clan can have this ability?" Tan Chu asked curiously.

"This... I don't know, but to be able to set such a powerful seal, except for His Majesty the Dragon Emperor, that is, it can only be the Blue Frost Elder. Hei Jiao thought and said.

"Do Hei Yun and the green dragon we saw have this ability?" Tan Chu asked suspiciously.

"No, the Black Rhyme God is outside all the year round, and rarely returns to the Dragon Clan, she doesn't have such a powerful divine power, Elder Cangwu I have seen it a few times before, although he is very strong, but he also does not have this ability." Hei Jiao thought for a moment and replied.

"You mean to say that there are only two people in the current dragon clan who can set this flame enchantment?" Tan Chu asked excitedly.

"I don't know." Hei Jiao had just been promoted to a real divine dragon, and he didn't know much about these characters that he could only look up to before.

"I know, I'll investigate this matter later, let's go take a look first." Tan Chu waved his hand and walked towards the depths of the cave with his three right-hand men.

After passing through the wall of fire, there is a deep cave in front of you.

The four of them turned several corners in a row, and after traveling about a few hundred meters, a red light suddenly appeared in front of them!

I saw that at the end of the cave, in the red light, a wide stone cave appeared in front of everyone...

It's as if the fire in this cave is constantly burning, like a huge furnace!

"What is this place?" Tan Chu asked in surprise.

"We don't know very well, but everyone has speculated that Elder Hongye may have built a giant furnace here, using divine iron to provide divine power and maintain the sealing energy of the Shadow Moon Canyon." Rainbow Shadow said.

"I see." Tan Chu was surprised in his heart, and strode towards the mouth of the cave...

Kuroka and the two Pegasi immediately stood in front of him, helping him keep an eye out for possible enemies.

Moving forward quickly, Tan Chu walked to the entrance of the cave and immediately looked inside...

I saw that in the huge stone cave, the red light kept talking, and a wave of heat came to my face...

Right in front of his eyes, he saw a huge tripod placed in the center of the stone cave, and bursts of red light came out of it!

There are pieces of golden iron ingots that shimmer with colorful glow in the giant ding, and under the big ding, a red flame that seems to never be extinguished is constantly heating the big ding.

I saw a halo of colored light rushing from the mouth of the ding to the top of the cave, a deep black hole, shooting towards the top of the mountain.

"Oh my God, it turns out that the core of the entire Shadow Moon Canyon is actually here?" Tan Chu exclaimed.

"Not only the Shadow Moon Canyon, but also the Hidden Sea Valley outside can only be maintained by relying on the divine power provided here." Pegasus Rainbow explained with a smile.

Yes...

Tan Chu listened to her words and instantly understood the situation here, but he didn't expect the guy who built this underwater world to come up with such a clever solution.

Use the divine power generated by the divine fire to barbecue the divine iron to provide the energy of the seal for the two places of the Hidden Sea Valley and the Shadow Moon Canyon...

Looking at the golden iron nails wrapped in colored halos on the four or five meter-high big ding, Tan Chu's heart suddenly became excited.

"Little brother, look over there, there's someone there!" Heijiao suddenly warned in a loud voice.

He had been looking around, dutifully protecting Tan Chu's safety, and suddenly found that in the corner of the stone hall, there seemed to be a stone bed, and there was a person lying on it.

"Don't worry, that guy is the guy that Elder Hong Ye just rescued a month, it seems that he was seriously injured and has not recovered yet." Rainbow Shadow explained.

"Let's go, let's go see who he is." Tan Chu was curious and immediately walked towards the side of the stone hall.

Under the protection of his three assistants, he walked to the far corner of the stone hall, only to see a large stone bed, and sure enough, there was an NPC wearing golden heavy armor...

This person was lying on his side towards the stone wall, and the black corner was dark, so that Tan Chu didn't see the name above his head for a while.

This is the great god of that race again?

Tan Chu, who was puzzled in his heart, immediately strode to the side of the stone bed to check the identity of this poor guy.

Who knew that this look suddenly made his eyes straighten, and he was instantly stunned...

Unexpectedly, this guy is still an acquaintance he knows!
