Chapter 502: Chapter 502: This is the Kill_1

"Did you leave someone behind to kill the Dark Dragon outside?"

Huo Liuli shook her head. She didn't know why there were gunshots outside the tunnel, either.

Everyone listened intently, suddenly, they heard the voices of Dark Dragon's subordinates.

"Damn it, stop shooting! There seems to be oil on the ground. Careful not to set it on fire and ignite the oil!"

"Get out, get out! What the hell is going on, I can't even see clearly!"

"The oil is ignited, the fire is too big, the vehicles can't get out, retreat, retreat to the tunnel, quickly…"

In an instant, rapid footsteps retreated back into the tunnel.

Xiao Yun looked in the direction of Dark Dragon's retreat. He saw them escaping in a mess, with fire trailing behind them. The fire was fierce, rushing towards them like flowing water.

A bodyguard with sharp eyes saw the reason for the approaching fire: "It's oil!"

Wherever the oil flowed, a blaze followed.
