Tang Zheng took a stride onto the bus, his hand clutching the door. With his left hand, he removed a hand grenade from his tactical vest, pulled the pin with his teeth, and tossed it into the underground parking lot once the safety was off.
Without any command from Tang Zheng, Lin Weiguo stepped on the gas. The tires of the bus spun rapidly, emitting enormous friction noise. Then, with a loud boom, the bus rushed forward, its outer wall scraping past the rotation door studded with unbroken glass, and sending broken shards flying everywhere.
Boom, boom, boom, the hand grenade exploded. In an instant, the underground parking lot filled with gasoline turned into a sea of flames. Five plumes of fire gushed up from the explosion, reaching the four-meter-high ceiling, blackening everything around it.
