The spatial ability of the half-step grandmaster Zhao Zhao, if not within his own Grotto Heaven, would have long been caught by Duke of Thunder.
Half-step grandmaster Zhao Zhao wanted to attack Duke of Thunder, but on one hand, Duke of Thunder's space movement was too fast, giving him few chances to launch powerful attacks. Even if he managed to hit Duke of Thunder with weaker attacks, they wouldn't have much effect.
On the other hand, Duke of Thunder's pursuit was relentless, and almost as soon as Zhao Zhao appeared, Duke of Thunder would appear beside him, followed by close combat.
Half-step grandmaster Zhao Zhao didn't want to incur any injuries. Currently, he's at the initial stage of being a half-step grandmaster, making him vulnerable to going berserk, and any injury greatly increased the possibility.
Furthermore, Duke of Thunder's attack power made him feel he would suffer severe wounds if hit.
