"The life core of planetary life appears here. Except for the first civilization, which is not clear about, there has never been planetary life at all when the second to the eighth civilization!"

Lin Feng knew very well how terrifying the planetary life was, and Lombett was also sure that it was already the end of the second civilization when it came to this world.

From the second civilization to the eighth civilization, there are no planetary life.

As for the human civilization of the ninth civilization, the strongest one is the saint's combat power, which is at best just four life leaps, and is the weakest among the nine civilizations.

There is only the mysterious first civilization, which seems to be faintly covered with a mysterious veil, which makes people unable to see clearly. If this blood-colored crystal is really the core of the planetary life, it may be related to the first civilization.

"Lonbetten, can you be sure this is the first civilization ruin?"

Lin Feng asked Lombett in his mind.

"It's impossible to confirm at all. The first time civilization is in vain, everything is very mysterious. I can't confirm unless I can get more information."

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

The vibration of the cave became more and more intense, and Lin Feng and the Invincible Fist Saint quickly left the Sixth Grotto and continued to walk towards the lower level.

It's strange that although the vibration is getting more and more intense, it will stop in a while. When Lin Feng and the Invincible Fist Saint both left the Sixth Grotto and entered another Grotto, the vibration has disappeared.

"Director, does the Longtou Eighteen Grotto extend all the way underground?"

Lin Feng asked curiously.

"No, Longtou Eighteen Grotto is just a general term, meaning there are eighteen Grottoes. But some of these eighteen Grottoes are parallel and some extend downwards, and cannot be generalized. We have explored these Grottoes once, but because we encountered the emperor-level monster, we could only give up. We are not even sure if there are more Grottoes."

Lin Feng was silent in his heart. It turned out that the Invincible Fist Saint had only explored eighteen caves. But thinking about it, there are emperor-level monsters in these caves. If they could explore them all, wouldn’t the Invincible Fist Saint have known the caves well for a long time? How could he ask Lin Feng for help and explore again?

"By the way, where are those emperor-level monsters?"

"Just in the 18th cave below! Last time I encountered the two emperor-level monsters there, but the losses were heavy and almost couldn't escape."

Thinking of the last experience, the Invincible Fist Saint is still a little scared, but at the same time he is a little cowardly. He is known as the Invincible Fist Saint, and his strength among the nine saints is among the top, but he was ruined by two emperor-level monsters and extremely embarrassed.

"Okay, then we will continue to explore, as if the vibration just now came from below."

Lin Feng also had a great curiosity about the cave below. If before, he had just made some contributions to the Invincible Fist Saint or to make some contributions to mankind.

So now, when he discovered the life core of planetary life, Lin Feng became very interested in this cave. The secrets contained in it, and even some things, may have a great effect on his practice.

Now Lin Feng takes the initiative to explore this grotto.

As the Invincible Fist Saint and Lin Feng continued to walk down, they passed through the seventh cave, the eighth cave, and the ninth cave...

The styles of these caves are basically the same, and the murals on the walls are also some strange things.

Moreover, in each cave, Lin Feng found an altar.

Of course, Lin Feng would not let go of these altars. Even Lombettane said that the core of life is a good thing, so he naturally had to "scrape" it clean.

So, whenever he encountered an altar, Lin Feng would break it. However, after reaching more than a dozen altars one after another, Lin Feng only found about five blood-colored crystals, which are the life core of planetary life.

The rest under the altar either didn't exist or turned into powder.

With the blood-colored crystal that Lin Feng got before, Lin Feng now has a total of six planet-level life core fragments.

Just as Lin Feng continued to go down, suddenly the vibration came again, and this time it was even more intense. Even Lin Feng could feel the source of the vibration, which was very close.

Now Lin Feng is on the 17th altar. According to the Invincible Fist Saint, the two emperor-level monsters are in the 18th cave.

"Saint Lin Feng, if you encounter two emperor-level monsters later, don't hold back and do your best. We join forces to kill an emperor-level monster first!"

"clear".

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

"Swoosh".

The two of them immediately accelerated their speed, and their eyes suddenly became clear, and it was a brand new cave.

This cave is very large, like a huge underground palace. Lin Feng has never seen such a huge underground building. Moreover, as soon as he stepped into this cave, Lin Feng's spear of destruction kept shaking, far more violently than any life core that had been shaken before.

"There is also a core of life here? And it is likely to be very large!"

Lin Feng's heart moved. Although the core of life is precious, they are very likely to face the emperor-level monster and still cannot be impulsive.

"Rumbling".

There was another violent shock in the cave. Lin Feng and the Invincible Fist Saint quietly stepped into the eighteenth cave. Before they walked far, they saw two emperor-level monsters on the altar in front, as if they were madly destroying the altar.

But this altar is very strange. There are countless murals on the altar, and chains are formed faintly. Every time the two emperor-level monsters hit, the chains will flash once, but there is almost no tendency to weaken.

The chains blocked the attacks of the two emperor-level monsters and blocked the two emperor-level monsters from the altar.

"It's these two emperor-level monsters, good guys, they are so much larger than the last time?"

A trace of splendor flashed in the eyes of the Invincible Fist Saint.

It was the first time that Lin Feng saw an emperor-level monster. He often heard the emperor-level monster from the saints. Lin Feng had already imagined the emperor-level monster very strongly.

But now, when seeing these two emperor-level monsters with their own eyes, Lin Feng still feels that his previous ideas are too conservative.

Each of the two emperor-level monsters in front of me was hundreds of meters long and dozens of meters high. One of them looked like a cow but not a cow, and was covered with black scales like iron armor, covering the whole body and exuding a fierce aura.

This emperor-level monster was called the Mo Emperor Demon by the Invincible Fist Saint!

The other one is hundreds of meters long, but the body is very short, only more than ten meters tall, but the whole body is flat, and it is like a flesh worm, constantly wriggling. There are almost hundreds of thick legs under its feet, and there are tentacles on its body, which can be hard or soft. It looks very hideous and terrifying.

This emperor-level monster was called the Thousand-Leaded Emperor Demon by the Invincible Fist Saint!

Both emperor-level monsters were concentrating on attacking the chains on the altar, and it seemed that they did not notice the intrusion of Lin Feng and the Invincible Fist Saint.

"Saint Lin Feng, the Mo Emperor Demon, has a strong defense and is difficult to deal with. We join forces first, and try our best to severely damage or even kill the Thousand-Level Emperor Demon!"

The Invincible Fist Saint and the two emperor-level monsters have fought each other, so they naturally know the background of the two emperor-level monsters.

"Okay, let's deal with the Thousand-Primary Emperor Demon first!"

Lin Feng took a deep breath and his eyes tightly locked in the Thousand-Level Emperor Demon.

"The Kingdom of Flames!"

"boom".
