747: Who made the Sifang Cave map?

Furthermore, based on the situation observed within the world stabilizing pearl, the Second Generation Black Dragon King likely anticipated his own death and prepared resurrection methods in advance.

In other words, this enemy wasn't a sudden appearance; he was there from the beginning.

Who could it be?

Chen Du had no clue about this. If one were to consider a power capable of killing a Starry Sky Warrior, the most direct thought would be the Nine Forbidden Zones.

However, it's impossible for creatures from the Forbidden Grounds to emerge; otherwise, the outside world would have known long ago.

If forced to name one, Chen Du believed the only power capable of killing a Starry Sky Warrior was the Land of Finality. Since it contains a Martial Artist Level Challenge Zone, it signifies that its power transcends that of a Starry Sky Warrior.

Moreover, behind it, there's the god of ending, an existence suspected to be a complete Egg God!

However, Chen Du also felt it was unlikely. If the god of ending truly wanted to kill the Second Generation Black Dragon King, then the latter shouldn't have had a chance to resurrect.

Furthermore, the purpose of the Land of Finality is most likely to cultivate Fourth-tier Martial Skills, and the Second Generation Black Dragon King had great potential to achieve this, so theoretically, he shouldn't have been killed.

From this, it can be inferred that there might be hidden monsters on Blue Star!

Also, the Sifang Cave's deduction was exactly as Chen Du guessed: it was indeed the corpse of the Mountain and Sea King.

Moreover, the Shan Hai Civilization was somewhat leaderless. They only had this one king in their generation, and no other existence capable of gaining the approval of all Natural Lifeforms emerged afterward.

Coupled with their inherent method of individual combat, the entire Shan Hai Civilization was essentially a disorganized mess.

As for the locations of the last two dangerous zones that Chen Du sought to find when he defeated the Mountain and Sea King...

No one in this world knew where they were, not even the collectively resurrected former Overlord-level Civilizations. Only the Mountain and Sea King himself knew this, and he never told anyone.

Presumably, he didn't want these most dangerous Energy Lifeforms to see the light of day again.

In addition, what disappointed Chen Du was how little the current three Overlord-level Civilizations knew about the Nine Forbidden Zones and Star Core Beasts.

Even a leader candidate like Sam didn't know much.

They were unaware of the existence of Star Core Beasts, only knowing that Star Cores were a metal with extraordinary abilities.

However, upon closer thought, it wasn't entirely incomprehensible, as Star Core Beasts were products from an era even more ancient than the former Overlord-level Civilizations, so only a living history like Yao Wangjing would know.

But they did know that Star Cores could upgrade planets, yet all three Overlord-level Civilizations chose to refuse this.

The reason was simple: they feared that after a planet upgraded, a surge of powerful individuals would emerge, shaking their absolute dominance.

Regarding the Nine Forbidden Zones, their speculation was that Monarch-level Civilizations were sealed within them.

Of the current Nine Forbidden Zones, only the following can be entered:

On the Surface: Land of Dusk Death, Cloudfall Skyriver

Underwater: Blood Sea World, Icy Tendril Abyss

In the Sky: Withered Mountain

These five are the Forbidden Grounds that all three current Overlord-level Civilizations have visited.

As for the other four, the Fantasy World can no longer be found. This Forbidden Ground, which resembles the Heavenly Book Civilization, is somewhat intriguing.

Unfortunately, Sam knew nothing about the Heavenly Book Civilization, nor did he have any profound impressions of the Sword Arrive Civilization. In his eyes, it was just an ordinary T2-level Great Civilization.

The Scarlet Territory is the Scarlet Fish; no one knew he was there, but these Overlord-level Civilizations did know that the entity of this Forbidden Ground was an alien race, and they had a label for him:

The largest Flesh and Blood Lifeform!

As for the Cloud Profound Empty Realm, its entrance could not be found at all.

The Withered Mountain, on the other hand, is the Forbidden Ground most visited by alien races. Basically, any Domain Warrior can safely enter, but it is completely empty, with nothing inside, not even danger.

Therefore, no one considered it one of the Nine Forbidden Zones, nor did they associate it with the mysterious second Forbidden Ground of the Firmament.

Moreover, this Withered Mountain was previously in the sea, near the mountain-sized boulders in the Blood Sea World.

Later, for unknown reasons, it floated into the Firmament, so no one suspected it to be the second Forbidden Ground of the Firmament.

After all, the divisions of sky, Surface, Underground, and underwater are all based on evidence.

This is also why the second Forbidden Ground of the Firmament has remained undiscovered; it was actually far away yet close at hand.

Finally, there is the Wailing Cave. Due to the War Fog, it became the only place whose location was known, yet no one could still reach it.

Unfortunately, Sam did not know the specific details about the Nine Forbidden Zones.

Or rather, the current three Overlord-level Civilizations, and even their Old Ancestors, did not know, as the Nine Forbidden Zones disappeared too quickly, leaving only an empty shell of a base camp behind.

What the Overlord-level Civilizations could do was explore within them, and there were indeed good things to be found. From Sam's account, the Second Generation Black Dragon King's ultimate resource, the Genesis Fish, was obtained in the Land of Dusk Death.

The sarcophagus inside was also discovered, including the three keyholes resembling grooves on its Surface.

This was consistent with what Durags said.

Indeed, the Genesis Fish, the world stabilizing pearl, and heavens favor were needed as the three ultimate resources to open the sarcophagus.

At that time, the Second Generation Black Dragon King, as expected, likely intended to open this sarcophagus, so after obtaining the Genesis Fish, he also found the world stabilizing pearl.

However, the abilities of the world stabilizing pearl remained a complete mystery; the Second Generation Black Dragon King never used it.

Although Chen Du had entered it, he couldn't confirm its specific abilities, only that the world stabilizing pearl was most likely an auxiliary ultimate resource.

Unfortunately, the Second Generation Black Dragon King never found the last key.

Moreover, from Sam, Chen Du also learned that their three Overlord-level Civilizations still don't know what ultimate resource the third key is.

However, this is not surprising, because under normal circumstances, heavens favor would transform into a form suitable for its user, and very few people knew about the existence of the sarcophagus.

In addition, Chen Du asked Sam a very old question:

Who made the Sifang Cave map?

But the other party actually didn't know about this matter.

Chen Du initially found it unbelievable, as the mapmaker's targets were Domain Warriors.

But he quickly understood. Although the Materials for these maps were all made from the body parts of Domain Warriors,

Because the maps were very small, not many Domain Warriors needed to be killed. Secondly, the perspective had changed; at that time, from the perspective of a High Martial Civilization, Domain Warriors were enormous beings.

Now, looking back, Domain Warriors, especially those who haven't reached Level 32, are considered unremarkable by Overlord-level Civilizations.

Similarly, Chen Du also obtained information about the ultimate resources controlled by the other two current Overlord-level Civilizations from Sam.
