Spoilers for all the worlds

"No," Master Gu Yi denied with a smile, her eyes a little deep, "This is a power that humans can only have after hundreds of years of industrialization."

Rick was silent, thoughts flickering in his mind, and finally nodded slightly.

Indeed, even if we don’t mention that Tony Stark and Bruce Wayne are cheating geniuses in their own right... just talking about the era they lived in, that was a hundred years after the Industrial Revolution.

The industrial revolution and scientific development were never achieved overnight... but were accumulated bit by bit through talent cultivation over time.

All kinds of black technology weapons of mass destruction were thrown out by Bruce Wayne for free.

Tokyo in the mirror world was completely razed to the ground, and the earth cracked open, sinking huge and extremely deep pits.

Finally, a terrifying scream suddenly sounded.

The void suddenly tore open, and the armor on the sky was knocked away by the terrifying shock wave. Even the first few sentences of Batman's armor directly shattered and exploded.

"Ang!" A giant black dragon emerged from the void. He was extremely huge, hundreds of meters tall, with bat-like wings spread out, even bigger than his size.

Black mist rose, and a skeleton wearing a wizard's robe stood coldly in the void. Beside him were translucent spirits roaring around him.

Yuuki Asuna's eyelids twitched, and then she spoke softly, "Those two...should be the boss on the ninety-ninth floor and the boss on the ninety-eighth floor, and the boss on the one hundredth floor...is Kayaba Akihiko himself. Data projection.”

Obviously, because Kayaba Akihiko was not logged in at the time, he was not controlled as the boss. However, the bosses on the 99th and 98th floors were completely controlled by the Clown Emperor...

"Very good!" Whitebeard chuckled. He stood up slowly, his huge body directly pushing up the ceiling, but this was the mirror world, so he had nothing to worry about.

"From a sensory perspective, the energy contained in these two guys is close to our level! Hmm... They must have been forcibly piled up by evil energy? That guy was really willing... But having said that, these guys seem to be the same as us. In comparison, it still lacks something very important?" Whitebeard's words were a little uncertain.

After a brief silence, he tilted his head and looked at Master Gu Yi with sharp eyes and said, "You solve it? I solve it? Or one person at a time?"

Master Gu Yi said nothing. The giant black dragon suddenly opened its mouth at this moment, and black flames suddenly spurted out, sweeping towards the group of people, and even the void was burned and distorted.

Whitebeard turned his head and punched out, and the void completely shattered at this moment.

The dense cracks extended into the distance at an unimaginable speed and collided with the body of the ink-black dragon, causing the scales on his chest to shatter and thick black blood to gush out.

"...It's really pure power." Master Gu Yi murmured. She looked indifferent on the surface, but her fists were clenched silently, and strange runes appeared on her forehead. Apparently he used all his power, even the dark power.

Whitebeard is too strong, and the power he controls is vibration.

This has led to the possibility that the mirror world will partially collapse if the Ancient Master does not use all his strength to maintain it.

The Black Lich raised his scepter high and chanted strange spells. The ghosts around him became more and more dense. At the same time, a large number of skeletons emerged from the ground, wearing armor and holding weapons.

"...You are fighting with me! You still have the time to summon?" Whitebeard's cold voice suddenly sounded in front of the black lich. Before he could even react, he wrapped his armed and domineering palms and trapped him. From his throat, pale white light rose up.

With a crisp sound, Whitebeard smashed it to the ground. Even if it was not deliberately targeted, the terrifying shock wave still caused the entire Japanese island under its feet to begin to collapse, and even affected the entire Asian plate... This attack was so terrifying that the Black Lich's body was completely shattered and blood splashed down.

"Next, it's time for us to take action."

Tushan Honghong took a slight breath. There was red demon power wrapped around her body, and the terrifying aura spread out around her.

Her figure disappeared in an instant, and in just one breath, she charged into the scattered army of skeletons that were shaken in the distance, completely smashing each skeleton to pieces at an unimaginable speed.

Not just skeletons, after the inky dragon interrupts Batman's weapons show. Like a tide of monsters, they once again emerged from another world that became real.

With a flick of her hand, Asuna Yuuki took out a thin sword. She moved forward at a high speed, and the impact fruit ability exploded. The shock wave that condensed into substance knocked the monster dragons, werewolves, and lizardmen into blood mist.

"...Is that my daughter?" Jie Chengzhangsan murmured, almost suspecting that he was dreaming now...

Although he had imagined that his daughter controlled extraordinary power before, he never imagined that the extraordinary power controlled by his daughter would be so strong...

Although Tokyo has been completely destroyed, it is difficult to find a comparison object in the ruins. However, when the sword was swung, a shock wave swept out. The densely packed monsters that spread for several kilometers were swept away by the shock wave, and he could still see it.

In other words... even if an army stands in front of Yusei Asuna, perhaps she can completely destroy it with one swing of her sword.

One enemy! Moreover, she was her daughter... This kind of thing that he only encountered in fantasy works actually appeared in front of him, making him feel as if he was in another world. He even wondered if he was in a dream now.

"Then it's time for me to head to my battlefield." Su Han said indifferently. The void in front of him twisted and he stepped into it.

"...Is this?" Rick was stunned for a moment, suddenly understood something, and looked at Bruce Wayne with some surprise.

"It seems you have guessed it," Master Gu Yi's face was as calm and gentle as ever, but there was a hint of gloom in his eyes, "The enemy is very cunning..."

"After being aware of the existence of the mirror world! That clown monster, on the one hand, sent strengthened monsters stationed on various levels in SAO, as well as monster lords to the mirror world to delay us."

"On the other hand, that guy led a small group of other elite monster lords and forcibly opened the way to the real world... and directly attacked Japan in the real world where we don't exist."
