Having undergone strict training, Ye Jian knew how to use the energy on her bent knees to offset the gravity. She landed on the tips of her toes and then the soles of her feet touched the ground. She offset the gravity so her legs weren't hurt when she jumped down.
Brother Hong died from the gunshot. The two bodyguards beside him knew that their opponent's sniper was eyeing them and they had no path of retreat. They were people living on the edge of death. Whether they were able to clear a bloody path of retreat depended on whether they were vicious enough to do it.
Obviously, these two bodyguards were vicious enough to do this. If not, they wouldn't have used their submachine guns to fight with the sniper directly.
Ye Jian didn't fire. She only had one bullet left in her sniper rifle. She would never use her last bullet until there was no other choice. This was sincere advice from a world-class sniper.
