As soon as Chengnan's voice fell, he heard a pop from nowhere, and then a puff of white smoke erupted from the black corridor in front of the three of them. Seeing this, Chengnan's heart jumped violently, and he reflexively pushed away Zhang Mei, who was standing on his right side, and then shouted: "Hold your breath, it may be poisonous!" "Imagine encountering a terrifying half-length white shadow in a corridor where you can't see your fingers, and then the corridor suddenly spews out a puff of white smoke, I believe no one will think that this white fog is normal. Zhang Mei was pushed back a few meters by Chengnan before falling to the ground, and at this time, the white smoke was swallowed up by Xiao Gang and Chengnan, who were not in a hurry. Zhang Mei, who was sitting on the ground, could only look at the figures of Chengnan and Xiaogang who were covered in white smoke.

"Seongnam! Xiao Gang. Zhang Mei stood up in surprise and wanted to rush in.

"Don't come in!" However, vaguely Zhang Mei heard a hoarse roar from Chengnan in the white smoke, and then saw the two figures in the white smoke slowly falling.

"No!" Seeing the two figures slowly falling, Zhang Mei screamed in despair. Just when Zhang Mei was desperate, she suddenly saw a figure in the white smoke quickly touching the place where Chengnan had fallen just now. Zhang Mei suddenly became alert, hurriedly grabbed the pistol that had just fallen to the ground and shouted, "Stop! Don't move! Move me to shoot again. However, the figure only froze, still rushing towards the position south of the city.

"Bang!" A loud bang pierced the silent darkness. Zhang Mei pulled the trigger the moment the figure moved. Zhang Mei only heard a cry of pain from the figure in the white smoke, and then the figure disappeared into the white smoke in a flash. Then Zhang Mei heard a running sound again, and Zhang Mei knew that she didn't hit the man, so she let him run. Seeing the white shadow disappear into the white smoke, Zhang Mei had no time to think, Zhang Mei quickly took off her coat and rushed to the white smoke, waving her clothes vigorously to disperse the white smoke. Under Zhang Mei's vigorous waving, the white smoke in front of her finally slowly dispersed. "Whew!" Seeing the white smoke disperse, Zhang Mei, who had been holding her breath, dared to let go and take a breath.

Zhang Mei took a deep breath and then turned to Chengnan and Xiao Gang. Then fell south of the city and fell to the ground with the faint light of the flashlight, and Zhang Mei quickly found them.

"South of the city... Xiao Gang! Zhang Mei shook Chengnan tremblingly, and seeing that Chengnan didn't react at all, she hurriedly stretched out her hand to probe at his snort. This detective Zhang Mei suddenly breathed a sigh of relief, only to see that Chengnan was wheezing evenly, it should be no big deal. It may refer to fainting. Zhang Mei was truly relieved after confirming that Xiao Gang was also safe and sound. Zhang Mei, who was at ease, had time to carefully observe the surrounding environment at this time. After a round of inspection, Zhang Mei soon found that there was a pool of blood not far from the place where Chengnan was lying, and there were no external injuries on Chengnan and Xiaogangliangren, so the blood must have been left by the white shadow.

"Looks like I hit him with that shot just now." Zhang Mei thought as she looked at the bloodstains under her feet.
