It was an Escape Technique!
Zhao Yang's eyes flashed, and as the knife swung towards him, he sidestepped to avoid it, then kicked out, sending his opponent flying sideways!
Suddenly, Zhao Yang sensed danger above his head. He didn't dare look up but immediately dashed to the side. Indeed, a knife plummeted from above, piercing the ground tile!
The blade slightly bent, the Ninja wielding the knife used the momentum to leap in midair, spinning rapidly and lunging at Zhao Yang!
Zhao Yang snorted coldly, snatched a book from the nearby desk, and threw it, striking the Ninja directly!
A muffled grunt was heard, and that Ninja instantly fell to the ground!
In the blink of an eye, three Ninjas were all seriously injured, and Zhao Yang knew there was still at least one person hiding in the shadows!
He stood quietly, waiting for the remaining Ninja to attack, but after a full five seconds, he no longer discerned any disturbances!
