Xu Xiangwen had already held back considerably. To put it in perspective, when he was in the intermediate trial grounds, the power of a single punch from him was equivalent to a grenade explosion.
Back then, Xu Xiangwen was only at the Star Shine Stage. That Star Martial Skill application technique must have been an initial application method of the Pure Yang Skill. Now that he had mastered using Star Martial Skills with his entire body, the power of this punch, enough to create a crater, was certainly stronger.
If he had used that move on Wang Lan, Wang Lan would have been mangled, even with Self Healing.
Xu Xiangwen was only using his speed to overwhelm Wang Lan; the slaps he threw weren't actually that powerful.
But even so, with Xu Xiangwen's speed advantage, Wang Lan could only endure the onslaught.
He was simply too fast.
