Chapter 311 - Demon Emperor!

"The life core of a planetary lifeform has appeared here. Apart from the first civilization, which Longbetham isn't clear about, planetary lifeform has never appeared from the second to the eighth civilizations!"

Lin Feng knew very well how formidable planetary lifeforms were. Longbetham was also very certain that by the time it descended into this world, it was already at the end of the second civilization.

From the second civilization to the eighth civilization, none of them gave rise to any planetary lifeforms.

As for the current human civilization, which was the ninth civilization, the strongest of them only had the combat power of Sages. They had at most undergone four life transitions, and it was the weakest of the nine civilizations.

Only the enigmatic first civilization seemed shrouded in a mysterious veil, and was difficult to discern. If this scarlet crystal was really the life core of a planetary lifeform, it might be related to the first civilization.

"Longbetham, are you sure this is the ruins of the first civilization?" Lin Feng asked Longbetham in his mind.

"There is no way to confirm it at all. The first civilization was shrouded in mystery, and everything about it was an enigma. I cannot confirm it unless more information can be obtained."

Lin Feng nodded. He only suspected that this place was related to the first civilization, and was not certain.

The tremors in the grotto became more and more intense. Lin Feng and the Invincible Fist Sage quickly left the sixth grotto and continued walking towards the lower levels.

Strangely enough, although the shaking became more and more intense, it would stop in a while. By the time Lin Feng and the Invincible Fist Sage left the sixth grotto and entered another, the shaking had already disappeared.

"Dean, does the Eighteen Grottoes of Dragonhead extend all the way underground?" Lin Feng asked curiously.

"No, the Eighteen Grottoes of Dragon Head is just a general term. It means that there are 18 grottoes. However, some of these 18 grottoes are parallel, and some extend downwards. They can't be generalized. We've explored these grottoes before, but as we encountered demon emperors, we could only give up. We're not even sure if there are more grottoes."

Lin Feng was silent. So the Invincible Fist Sage had only explored 18 grottoes. However, on second thought, this made sense. There were demon emperors in these grottoes. If he could explore them all, wouldn't the Invincible Fist Sage already know the grottoes like the back of his hand? Why would he ask Lin Feng for help to explore it again?

"By the way, where are those demon emperors?"

"They're in the eighteenth grotto below! Last time, I encountered those two demon emperors there. I suffered heavy losses and almost didn't make it out."

Thinking of his previous experience, the Invincible Fist Sage still had some lingering fear, but at the same time, he felt a little ashamed. He was known as the Invincible Fist Sage, and his strength was ranked in the top few among the Nine Sages, yet he was defeated by two demon emperors and ended up in an incomparably sorry state.

"All right, let's continue exploring then. It seems like those tremors just now also came from below."

Lin Feng was also very curious about the grottoes below. Previously, he had only wanted to help the Invincible Fist Sage or make some contributions to humanity.

Now, after discovering the life core of a planetary lifeform, Lin Feng was very interested in these grottoes. The secrets contained in it might even be very useful for his cultivation.

Now, Lin Feng was the one taking the initiative to explore this grotto.

As the Invincible Fist Sage and Lin Feng continued down, they passed through the seventh, eighth, and ninth grotto…

The style of these grottoes was basically similar. The murals on the walls also depicted some strange things.

Moreover, Lin Feng discovered an altar in every grotto.

Seeing these altars, Lin Feng naturally would not pass on them. Even Longbetham had said that life cores were good stuff. He naturally had to "plunder" them all.

Hence, Lin Feng would shatter every altar he encountered. However, after encountering more than ten altars in succession, Lin Feng only found about five scarlet crystals, which were the life cores of planetary lifeforms.

Under the other altars, there was either none, or the crystal had been reduced to dust.

Including the scarlet crystal that Lin Feng had obtained previously, Lin Feng now had a total of six life core fragments of planetary lifeforms.

Just as Lin Feng continued to descend, the tremors suddenly occurred again. This time, they were even more intense. Lin Feng could even sense that the source of the tremors was very close.

Now, Lin Feng was already at the 17th altar. According to the Invincible Fist Sage, the two demon emperors were in the 18th grotto.

"Sage Lin Feng, if we encounter two demon emperors later, don't hold back. Do your best. The two of us will join forces and kill one demon emperor first!"

"Understood."

Lin Feng nodded. The Invincible Fist Sage had been waiting for this day for a long time.

Swoosh. Swoosh.

The two of them immediately sped up. The world opened up before them. It was a brand-new grotto.

This grotto was huge, like a huge underground palace. Lin Feng had never seen such a huge underground building. Moreover, as soon as he stepped into this grotto, Lin Feng's Spear of Destruction kept shaking, far more violently than when encountering any life core before.

"There's a life core here too? And it might be very large!"

Lin Feng's heart skipped a beat. Although life cores were precious, it was very likely that they would face demon emperors. They could not be rash.

Rumble.

The grotto shook violently again. Lin Feng and the Invincible Fist Sage quietly stepped into the eighteenth grotto. Before long, they saw two demon emperors on the altar in front of them. They seemed to be destroying the altar in a frenzy.

However, this altar was very strange. There were countless murals on the altar, and they vaguely formed chains. Every time the two demon emperors collided with the altar, the chains would flicker, but there was almost no sign of weakening.

The chains resisted the attacks of the two demon emperors, blocking the two demon emperors outside the altar.

"It's these two demon emperors. Impressive. They're actually so much larger than the last time."

A sharp glint flashed across the Invincible Fist Sage's eyes.

This was also the first time Lin Feng had seen a demon emperor. Having often heard about demon emperors from the Sages, Lin Feng already imagined that demon emperors were very powerful.

But now, seeing these two demon emperors with his own eyes, Lin Feng still felt that his previous thoughts were too conservative.

The two demon emperors in front of him were each over a hundred meters long and dozens of meters tall. One of them looked similar to a bull. Its entire body was covered in black scales that appeared like metal armor, and it emitted a fiendish aura.

This demon emperor was called the Demon Emperor Mo by the Invincible Fist Sage!

The other one was also over a hundred meters long, but its body was very short, only about ten meters tall. Its entire body was flat, and its body was constantly squirming like a fleshworm. There were hundreds of thick legs beneath it, and there were tentacles that could harden or soften on its body. It looked very sinister and terrifying.

This demon emperor was called the Demon Emperor Millipede by the Invincible Fist Sage!

The two demon emperors were focused on attacking the chains on the altar, and did not seem to have noticed the intrusion of Lin Feng and the Invincible Fist Sage.

"Sage Lin Feng, that Demon Emperor Mo's defense is very strong and difficult to deal with. The two of us will join forces first and try our best to severely injure or even kill the Demon Emperor Millipede!"

The Invincible Fist Sage had fought with two demon emperors before, so he naturally knew the background of the two demon emperors.

"All right, let's deal with the Demon Emperor Millipede first!"

Lin Feng took a deep breath and locked his gaze on the Demon Emperor Millipede.

"Divine Kingdom of Fire!"

Boom.

Before the two demon emperors noticed, the Invincible Fist Sage instantly unleashed all his Astral Power. The Divine Kingdom of Fire descended in an instant, enveloping the entire grotto.
