A few seconds ago.
Dimensional Gap
Asmodeus led the gods of Liyue's lineage straight to the 'underworld'. As the supreme god who controls all the 'space rules' of the 'Teyvat Universe', he could penetrate everything in the entire underworld at a glance. Then he passed everything he saw to the army of gods behind him.
"With just two high-level god-level demons and two mid-level god-level demons, plus 10,000 non-god-level demons, Morax, and a standard Teyvat system, we can conquer that world," Asmodeus spoke with indifference, his golden eyes full of majesty. "I'm here to suppress the world's instinct to resist."
After saying that, he raised his hand, and the space rules condensed into a black-red cube with a red halo, projecting toward the world film in front of him. Even in the "dimensional gap," the speed of the space cubes was such that they struck the world membrane almost instantly.
Although the attack seemed casual, it was actually a serious blow. The barriers of the world are far more resistant to 'foreign objects' than those within the world. The space cube bloomed like fireworks upon impact, splitting into countless smaller space cubes. The 'world membrane' was violently torn open, leaving a massive wound thousands of kilometers wide. The space cubes formed a vortex and lodged themselves in the wound, preventing the world from healing itself.
Such a scene was akin to the world opening its eyes. At this moment, the world instinctively began to fight back. The repulsive force of the 'Underworld' blasted towards Asmodeus. Asmodeus remained expressionless, and the shadow of the 'Teyvat Universe' appeared behind him. All the counterattacks of the 'world' were absorbed by the 'Teyvat Universe'. He constantly unleashed the "space rules" of this world, with the tentacles formed by connected space cubes extending toward the special world's interior. The power of the 'Teyvat Universe' suppressed the 'World Instinct'.
To use an analogy, if the world was compared to a human being, Asmodeus' actions were akin to knocking the person unconscious, rendering him unable to resist, and allowing them to do as they pleased.
Morax, holding his spear, responded, "I understand."
A divine ring bearing the rock element symbol appeared behind him. The rules of rock elements poured towards the torn world membrane. Although that 'other world' lacked the power of the 'rock element', and even though the world's rules were subject to ownership, this invasion was backed by the entire 'Teyvat Universe'. At this time, the source of power for everyone performing tasks was the connected 'Teyvat Universe'. Thus, there was no concern of 'acclimatization'.
The 'rules' of a world with gods are always in possession. If not for Teyvat's backing, even the main god might lose to a superior god when fighting in a 'different world' due to home-field advantage.
"Let's deter the entire world first," Morax declared. "The sky moves and everything moves."
Zhongli, using only ten percent of his strength, raised the sky star. After all, he intended to intimidate rather than kill all the demons. Living demons were far more valuable than dead ones. If all the demons in the 'underworld' could be drawn into the divine system, it would be a great achievement for Liyue's lineage.
A massive 'sky star', fifty kilometers wide, fell from the rotating sky towards the 'demon army'. This was not just a rock element-formed stone, but a structure imbued with 'rules' and a thick aura. The very presence of the 'celestial star' instantly oppressed the 'demon army'. Whether they were lower-level demons or higher-level demons, all were swatted to the ground, like flies under the weight of a fly swatter.
The sound of the demons falling to the ground was like the patter of rain. If a scientist were to analyze the phenomenon, they might think it was 'gravity'. The oppressive presence of the rock element indeed had similarities to gravity but was fundamentally different.
The sudden terror caused the fallen demons to scream in fear.
"Ahhh!"
"Help! The stars in the sky have fallen to the underworld!"
"No! I don't want to die!"
"I can't move!"
"Your Majesty the Demon King! I don't want to die!"
Rias was crushed to the ground, looking up at the 'sky star' as it fell. The fear grew as the distance quickly shortened, and her eyes filled with despair. The 'sky star' above her head was so massive it occupied her entire field of vision. Despair was all she felt, and one thought crossed her mind—death. All demons here would die. Even this vast area would have its terrain permanently altered due to the celestial star.
Only the 'Demon Kings' could move under the 'celestial star'. After a brief moment of panic, the four demon kings burst forth with all their strength, rushing to attack the celestial star without further thought. Four streams of light rushed towards the 'celestial star', the roar spreading throughout the space.
"Destroying Magic Bullet!"
"Demon Energy Super Freeze!"
"The Overlord's Formula!"
"Absolute Counterattack!"
Magic circles of red, blue, cyan, and orange spread out beneath the 'Sky Star' like firecrackers, expanding in all directions at a tremendous speed. In the blink of an eye, the magic circles covered the entire visible space. Red lightning magic bullets, frozen light beams, cyan magic threads, and rebounding light waves shot out in a continuous stream from every magic circle. The dazzling magical light instantly turned the sky pale.
These attacks carried the power of 'rules'. Sirzechs, as the strongest demon, possessed the 'will to destroy'. Ajuka mastered the 'direction rule', able to freely control the direction of any attack and even amplify its speed and power. Farbiwin wielded the rules of defensive rebounds, and Serafall commanded the rules of ice.
Rumble, rumble, rumble—
Countless magic attacks bombarded the 'Sky Star', but even with such intense attacks, the celestial star barely slowed, merely peeling a layer off its surface. As the 'Sky Star' drew closer, the sense of oppression grew even heavier, suppressing even floating rocks and causing them to fall from the sky.
"Ahhhhh!"
The four demon kings squeezed every last ounce of power from their bodies, roaring with all their might. The speed of the magic circle's attacks doubled, illuminating the underworld with their dazzling light.
Rumble, rumble, rumble—
Finally, their efforts seemed to work, as the star shattered under the intense barrage of magic attacks. The explosion resounded across the 'underworld', and the fragments of the exploding star shot out in all directions. These fragments spread throughout the 'underworld', each one capable of killing a top-level demon.
Hehehe—
Countless demons were caught in the aftermath, turning to ash from the bombardment of the meteorite fragments.
Boom—
The four demon kings were struck down by the shockwave, crashing through floating mountains before being blasted to the ground. The earth shook like a meteorite had struck it, creating a thousand-meter-wide crater. The four demon kings lay exhausted at the center of the pit, looking above with reddened, trembling eyes.
The 'Sky Star' was gone, but the being who had released it was approaching, accompanied by a group of gods above the demon king level. A divine ring shone behind him, and his golden eyes looked arrogantly upon the earth. His aura, far surpassing even that of the 'Beyond One', oppressed the entire underworld.
