The siblings are the same age, both practice their family's martial arts, and can both use a rudimentary form of energy called internal force. He is male and has a physical advantage, so how could he possibly lose?

The two exchanged blows, quickly going through dozens of moves.

Zuan was originally full of confidence. You see, he once held the power of the Singularity World and experienced a god-like feeling in that world. In a sense, he was like a true god in that world.

His understanding of martial arts, laws, mysteries, and so on surpasses that of countless beings with higher cultivation levels than him.

He even had the confidence that even if a true god were at the same level as him, he might not necessarily lose.

But it wasn't until this moment that he realized how narrow-minded he had been.

With his level of skill, it wouldn't be difficult for him to master the physical techniques that Guo Polu originally knew, which were called martial arts, in the blink of an eye. He could even unleash a power far exceeding that of Guo Polu himself.

But to my surprise, the fireworks were just as impressive; her understanding of martial arts was even better than mine!

He was at a disadvantage almost from the very beginning, and was quickly hit multiple times.

However, he was determined and would not easily admit defeat. He gritted his teeth and persisted in exchanging blows with his opponent while pondering the intricacies of his opponent's moves.

He didn't know how much time had passed before his opponent finally found an opening, grabbed his hands, and pinned him to the bed.

"Do you submit or not?" Fireworks asked smugly.

"I refuse to accept this!" Zu An twisted his waist and tried to use his legs to clamp down on his opponent and gain the upper hand.

However, Fireworks' waist undulated like waves, always managing to cleverly deflect his force. On the contrary, she eventually found an opportunity to press down on him, rendering him unable to move.

"Are you convinced now?" Fireworks had lost her extraordinary strength after all. The simple hand-to-hand combat just now relied on her own strength, and she was also a little out of breath. When the two looked at each other, they realized that their faces were very close.

Just then, the door opened: "Xiang'er, Polu, Mother just asked you to do something... What were you doing?"
