Alex was swarmed by people, asking him how he was so strong. They understood that he had been training with his sword, but this was a bit too strong still.
He was challenged by people too. Now that he and Fang Yimu had fought, they could use them to clear their first battles of the day.
"Sure, but I won't give out a pill if you win," Alex said. "Unless you want to make it an actual fight with you having a chance to lose."
Nobody wanted that.
Alex still didn't hold back much, using as much Sword Intent as he could. Fighting these strong people was an incredible chance he wasn't gonna give up just to give them a win.
He did give them a win in the end though, as that was what he had promised. And no one complained about him fighting seriously either as he used nothing more than Sword Intent.
If he had been seriously fighting, there were many other ways for him to make it hard for them to win, but he hadn't.
