Because his robots were the best at close combat, far superior even to many humans.
However, those robots he was so proud of were obliterated within three seconds by Shangguan Xiu. He tore them apart into scraps of metal with his bare hands the moment he burst through the door.
Boss Ke gaped in shock, his voice trembling with disbelief: "Impossible! How has he suddenly become so strong? That serum was meant to extend lifespan, not enhance physical strength…"
The four people standing nearby had also witnessed Shangguan Xiu's astonishing display of power and were equally terrified. Seeing Boss Ke's reaction, they panicked and started questioning him, "Boss Ke, let's not lose our heads. Hurry and check—can you control him? We have to stop him from destroying the castle any further!"
"Don't panic, let me check." Boss Ke finally snapped out of his daze and began to think about ways to control the abnormally violent Shangguan Xiu.
