Collapse, harem after the end of the world

Hei Xier's attacks grew increasingly frantic, constantly changing her tactics, trying to find Xier's weaknesses. Her tentacles swooped down on her like venomous snakes, her sickle slashing through the air like lightning. However, Xier always managed to vanish at the crucial moment, only to reappear with a fierce counterattack.

Hei Xier began to feel an unprecedented sense of defeat, her strength seemingly suppressed by Xier. She gritted her teeth unwillingly, her entire aura erupting. Black air surrounded her like a violent storm, emitting an even more terrifying and powerful energy.

Hei Xier launched another fierce attack on Xier. Each of her attacks was filled with boundless power, and her strength and speed reached the extreme. However, there was no trace of fear or despair in Xier's eyes. Instead, there was a firm determination.

Xi'er gripped the sickle tightly in her hand, her muscles tensed. She remained calm and decisive in the face of Hei Xi'er's attacks. She kept dodging Hei Xi'er's attacks while always looking for opportunities to counterattack.

In the dark night sky, the figures of Hei Xier and Xier intertwined, like a fierce scene. Hei Xier's power was like a violent storm, and Xier's counterattack was as swift as lightning. Every confrontation between the two brought bursts of harsh metal friction, and the air was filled with a tense atmosphere.

Hei Xier sensed Xier's persistence and unyielding spirit, and a wave of frustration surged within her once again. She knew that only by breaking Xier's resolve could she achieve ultimate victory. She began to gather her strength, preparing for the final blow. A different light glimmered in her eyes; now, she had to further validate Xier's convictions.

Darkness and light reached their limits in this fierce battle. Black Xier and Xier fearlessly rushed toward each other, each radiating unparalleled power. Ultimately, Xier triumphed over Black Xier by a narrow margin.

"You win. Now I'll give you this power." Hei Xier looked at Xier in front of him with a determined look, as if he had completely admitted defeat. He sat on the ground, quietly waiting for Xier's next move.

However, what she didn't expect was that Xier hugged her the next moment. She couldn't understand this action, she just accepted it silently.

"No, no..." Xier looked at Hei Xier, tears welling up in her eyes. She finally understood Hei Xier's true intention.

From the previous battle, Xier had seen through Hei Xier's mind. From the beginning, the opponent did not give his all, but deliberately let himself be defeated. All of this was for her growth.

"So you've already figured it out." Hei Xier said with a headache. She didn't want to embarrass Xier, but she couldn't help but work hard for her own destiny.

"After all, we are one, aren't we?" Xi'er replied gently. She understood that in this world, both darkness and light, were part of her. She was no longer afraid of darkness, because she knew she could harness it and turn it into strength.

"Okay, can you lend me your power?" Xier looked at Hei Xier and said.

"You've already won, why are you asking me this?"

Hei Xier curled her lips at this time.

When the two held hands together, a huge force surged out of Xier's body.

Adam watched this scene and immediately knew that Xier's true power had finally awakened.
