Returning to the ultra-ancient era was something Yu Zhou spoke of as if it were utterly trivial.
Masaki, however, was visibly stunned. He carefully examined the two warriors standing to Yu Zhou's left and right—true ultra-ancient warriors who had genuinely traversed time to reach this era.
Yu Zhou then explained to Achilles and Herau that the person before them was not Cain himself, but Masaki Keigo, a man of the new era who used the giant's combat body.
Achilles and Herau were already familiar with the concept of combat bodies. After understanding the explanation, both nodded in acknowledgment.
For convenience, everyone undoes their transformations.
Yet the moment Masaki returned to his human form, Achilles and Herau were dumbfounded once again. They immediately turned to Yu Zhou.
"Tiga, and you still say he isn't Prince Cain?!"
Yu Zhou looked over at Masaki.
Well—he really did look quite similar.
"He just looks alike. Just looks alike," Yu Zhou explained helplessly.
"Masaki, these past few days I discovered that the core of the Space-Time City can—"
Before Yu Zhou could finish, two figures emerged from behind the main hall of the Space-Time City.
They were Hudra and Darramb.
Hudra had intended to discuss matters regarding the city's core with Masaki, but the moment he saw Yu Zhou—and Achilles and Herau beside him—he froze.
"You are…"
"You're Achilles and Herau?!"
Hudra searched his memories of thirty million years ago, and the names quickly surfaced.
Back then, before anyone had become giants—before even the Dark King Cthulhu had fully emerged—they had been friends.
"You're… Hudra and Darramb!!!"
Despite changes in appearance and attire, Achilles and Herau immediately recognized them.
"You two… have you lived for thirty million years as well?!"
Hudra was deeply shocked by their presence.
During the great war between the Giants of Light and Darkness in the ultra-ancient era, the Light Giants had been annihilated.
Hudra and Darramb had believed Achilles and Herau had perished in that conflict.
Yet now, they stood before them, alive and well.
"Lived for thirty million years? No," Achilles shook his head.
"We travelled through time together with Tiga."
"Wait—then does that mean you spent thirty million years sealed inside stone statues?"
Herau reacted a bit more slowly, but arrived at the thought.
At his question, both Hudra and Darramb nodded in silence.
Then Hudra suddenly caught the key point in Achilles's words.
"You said… you came from thirty million years ago together with Tiga?"
His voice trembled.
"Then where is Tiga? Where is Tiga?!"
"As long as Tiga is here, he can save the Lady!"
"Tiga… isn't he right here?"
Herau scratched his head and pointed at Yu Zhou.
"Him?" Hudra's face darkened as he looked at Yu Zhou.
"He is not Tiga."
"He is not the Tiga from thirty million years ago!"
"That's right—he's just trash!"
Darramb echoed bluntly, his tone filled with prejudice toward Yu Zhou.
"This…"
Achilles and Herau exchanged glances, completely confused.
Yu Zhou was clearly Tiga—so why did Hudra and Darramb refuse to acknowledge him?
Seeing Hudra and Darramb so agitated, Masaki stepped in to mediate and calm the situation.
"…Actually," Yu Zhou finally spoke, his expression complex as he looked at the two of them,
"I really am Tiga."
"I am the Tiga from thirty million years ago."
"Yu Zhou… are you saying—?"
Masaki suddenly realized something.
"Yes," Yu Zhou nodded.
"I originally intended to go to the ultra-ancient era to find the original Tiga and borrow his power to save Camearra."
"But when I arrived, I discovered that at that time, there were no Giants of Light, no Dark Giants."
"It was only after experiencing one event after another that I realized something."
"I had already entered history itself."
"I became Tiga."
"The true Tiga… is me."
Yu Zhou then recounted everything that had happened in the ultra-ancient era.
The first appearance of monsters in Fuhuo City.
The first manifestation of giants.
The Light Particle Converter and the Plasma Spark.
Human evolution through hearts of light.
The war between light and darkness.
And finally, the massive crustal movement and the reformation of Earth.
The revelations left Masaki utterly stunned.
Hudra and Darramb found it equally unbelievable.
Events from thirty million years ago flowed from Yu Zhou's mouth as though he had lived through them personally.
Which, in truth, he had.
"You really are Tiga."
Hudra finally spoke, staring intently at Yu Zhou.
From initial belief, to doubt born of disappointment, and finally to absolute confirmation—
Hudra now fully accepted that Yu Zhou was Tiga.
After all, he had brought Achilles and Herau back from thirty million years ago.
"I'm sorry," Yu Zhou said quietly.
"Back then, the darkness of Cthulhu still lingered within your bodies. It required time to be purified, which is why I sealed you."
Before traveling to the ultra-ancient era, Yu Zhou had believed that sealing Camearra and the others had nothing to do with him personally.
Now, having returned, he understood his responsibility.
Seeing Hudra and Darramb again filled him with guilt.
"You… sigh."
Hudra pointed at Yu Zhou, holding back his emotions before letting out a long sigh.
"I've already forgiven you," Darramb said bluntly.
"But tell me this—can you save the Lady or not?"
Now that Yu Zhou's identity as Tiga was confirmed, Darramb's greatest concern was whether Camearra could be rescued.
"Yes."
Yu Zhou nodded firmly.
The reason he had come to the Space-Time City was precisely to bring them to his world—to let them witness him saving Camearra.
And, incidentally, to deal with the remaining monsters as well.
"Then what are you waiting for? Let's go!"
Upon hearing that Camearra could be saved, both Hudra and Darramb became visibly excited.
Masaki felt relieved as well.
"Alright," Yu Zhou said.
"We'll depart immediately. However, something has happened in my world."
He turned to Masaki.
"Are you free to come along and fight some monsters?"
"No problem."
Masaki accepted without hesitation.
