The most powerful sniper

Description

There is no system for time travel, and just when Xiao Nai was desperate, he got his own plug-in, Brother Umbrella's glorious knowledge and skills, as well as an effective hand speed that can hit more than 800 APM and the corresponding neural reaction speed.
So Xiao Nai followed the original story that a sniper who can't throw grenades is not a good sharpshooter and embarked on a career path.
Xiao Nai's opponents said this about Xiao Nai: You never know what Xiao Nai can pull out from behind.
Ye Xiu: He misses an old friend of mine...
Zhou Zekai said: It is very strong and unfathomable.
Qiao Jingjing: I agree with this, but mine was detected by him.
