Fourth floor

The Demigod, for fear of getting killed by Xuanyuan's next attack raised his sword and prepared to execute his Trump card to deal with Xuanyuan.

On the other hand, Xuanyuan realized he had to finish the battle quickly as he could only maintain the berserk state for a little over ten seconds more. Afterwards, he'd be subjected to a weakened state and if he couldn't defeat the Demigod before then, he'd have to forfeit the challenge instead, hence he also prepared his ultimate attack.

He threw the sabre in his hands into the sky as he activated a Magic scroll in his hands. External items were forbidden in the Ancient tower but he drew the array himself so it could be somehow considered as part of his powers.
