Victory

His current ranking was enough for the challenge, so not waiting for any more, he quickly sent the challenge request. But it wasn't going to be immediately accepted; he might need to wait a few days, which he can wait. 

He came out from the Dimension Battle world for two days and went to rest waiting for the guy to accept his challenge.

Two days later, the challenge was accepted, and he was ready to face the millionth genius in the universe. 

He quickly entered the Dimension Battle world. The notification he had been waiting for appeared in his vision.

[Challenge Accepted. Preparing the arena for your battle.]

A faint smile crossed his lips. "Finally," he murmured.

Without hesitation, he appeared in the arena. Unlike the last battle, this time, the arena seemed darker, with a strange, oppressive atmosphere.
