Relying on the super-fast speed of the Sun-Chasing Dragon’s Wings, Huang Yi quickly arrived at the First World.

This planet is peaceful and serene, with vast aerial cities drifting among the floating clouds. Below, the landscapes are majestic, bustling with thriving life, forming a stark contrast with the Second World, which is suffering hardships.

However, in certain ocean areas, one can still see patches of black spots, like stains on the sea surface, which were previously polluted by the Demon Clan.

The Demon Clan had previously sent experts here to wage war against the Nagas, but later their focus shifted back to the Second World, and the Demon Clan in the First World quieted down, leaving only a few scattered outposts without launching large-scale attacks again.

Huang Yi flew skillfully towards one of the areas that had been polluted by the Demon Clan.

Soon, at the end of the vast ocean, a piece of land appeared. This land showed the blackness of demonic pollution, barren and empty, littered with abandoned defensive fortifications. Several towers had collapsed, chaotic and disorderly, and there were no longer any signs of the Demon Clan, only some inferior demons, eyeless demons, demon wolves, and other remnants wandering around.

In the very center of that land was a massive underground hole, from which demonic qi ceaselessly spread outward, unfathomably deep.

This land was once the stronghold of the Demon Clan during their conquest of the First World, and that massive hole was the Demon Cave of several Demon Kings in the First World.

Huang Yi had explored here once before. This time, he returned to search for a Demon King’s Gate to teleport to the Demon Race Microcosm.

In fact, there was a Demon King’s Gate in the Second World, in the Abyss of Hero’s Continent. However, these Demon King’s Gates had all been destroyed, which is why he traveled far to the First World to search for one.

The Demons sent billions of troops to conquer the First World, and the only way to quickly withdraw these forces was by constructing a Demon King’s Gate.

The most suitable place to build a Demon King’s Gate was in that unfathomable Demon Cave, where the aura and formations left by several Demon Kings remain. Outsiders would not dare enter easily, ensuring the safety of the Demon King’s Gate.

Huang Yi flew directly over the Demon Cave, folded his wings, and fell down into it.

When he fell to the cave entrance, a faint black film appeared above the cave, isolating the Demon Cave from the outside world.

This was a barrier, but compared to last time, its strength was much weaker, and Huang Yi effortlessly penetrated it without any measures.

He had already used the Racial Fusion Serum to fuse all his bloodlines within his body, possessing a complete Demon Clan bloodline even in his normal form, which allowed him to pass the barrier unimpeded.

Once inside the Demon Cave, everything turned pitch black, with no light at hand, yet with his Clan of Light visual abilities, Huang Yi could still easily see his surroundings.

The cave walls were worn and flaked in many places, stained with dried demonic blood, showing that no one had entered or exited for a long time.

After falling for some time, Huang Yi finally landed at the bottom, arriving in a tunnel.

He followed the tunnel forward until he reached a huge underground space.

This underground space originally stored the life tokens of the Billion Demon Army, but now those life tokens had all disappeared, their surroundings scattered with various abandoned Demon Clan weapons and some demon casualties’ bones, reeking with a foul stench.

In mid-air, in the underground space, stood a black gateway, with a black barrier on the gate.

Indeed, it was a Demon King’s Gate!

Huang Yi’s guess was correct; the Demon Clan had indeed used a Demon King’s Gate to teleport their grand army back to their Demon Race Microcosm.

The next moment, Huang Yi immediately rushed into the Demon King’s Gate.

If it were someone else, upon collision with the Demon King’s Gate, they’d be repelled. No matter how strong they were, they couldn’t forcefully teleport and could only destroy this Demon King’s Gate at most.

However, because of his demonic lineage, Huang Yi was recognized as one of their own by the Demon King’s Gate, successfully activating the teleportation function, and he vanished beyond the black barrier on the gate.

After a considerable time, Huang Yi felt the tug of the teleportation power finally fade, arriving at a new place.

This was a space of void, with a black backdrop, floating with debris, corpses, and skeletons everywhere, eerily terrifying, precisely the Demon Race Microcosm.

Yet the whole space trembled, with cracks appearing throughout, strange illusions flickering non-stop, stars exploding, nebulae shattering, as if the starry sky was collapsing into annihilation, with doomsday imminent.

This indicated that the Demon Race Microcosm was in an extremely unstable state, either subjected to great pressure or significantly lacking in the strength to maintain the microcosm. Considering the King of Hell frequently demanded other Demon Kings to borrow their true body’s power and intensify the refinement of the Second World, it was likely the latter reason.

Huang Yi flew straight forward, passing through a band of crumbling debris, and suddenly, six planets appeared ahead.

Among them, the one in the center was the grandest and most dazzling, seemingly like a sun. The other five planets were aligned on either side, rotating around it like a galaxy.

These were the planets of the Six Great Demon Kings. The first time Huang Yi came to the Demon Race Microcosm, he saw seven planets, but with the death of the Queen of Agony, the Star of Pain had been refined, and now the Demon Race Microcosm was left with these six planets.

The six planets were rotating, but due to the microcosm’s instability, asteroids occasionally fell onto them, creating craters on their surfaces and triggering ripple-like shockwaves, killing countless demons on the planets.

Huang Yi looked around, searching for something, but soon furrowed his brows slightly.

He smacked his lips, and a trace of blood spilled from the corner of his mouth, the drop of blood with a faint golden glow, quite peculiar.

He carefully tasted the drop of blood, closed his eyes, and concentrated on perceiving.

This drop of blood was from the Sagittarius he had just devoured in the Second World, and he was using his Blood Dragon Clan abilities to track the position of Sagittarius’s true body based on this drop of blood.

Sagittarius’s form was larger than planets, easily visible at a glance, yet was not appearing in the Demon Race Microcosm now.

This suggested either Sagittarius was not in the Demon Race Microcosm or had shrunk and hidden in some corner.

After a while, Huang Yi suddenly opened his eyes and turned towards one of the planets.

He perceived that Sagittarius’s true body was located in a corner of that planet.
