Li Pan figured that the corporate dogs wouldn't be so naive as to believe that if a nuke didn't do the trick, a super bomb would be enough to kill him.
They probably knew he was good at parkour and that the terrain was complicated, so they opted to throw a bomb first to clear an open battlefield, then follow up with other super weapons to chase him down. If he acted rashly, he'd likely be surrounded and targeted by several sniper rifles again.
What? Could he just use a spell to escape directly?
He could, but... why should he run?
It was only natural to hit back when someone hit you, right?
Li Pan no longer needed to run because he! had! upgraded!
Right! Just do it!
Cough cough, of course, Li Pan was now a tiny bit stronger. Previously, he couldn't even take one bullet, but now he might withstand a couple. However, if someone swept through with a compassionate velocity of three thousand six hundred rotations in a second, how would he deal with that?
