Escaping the E.N.D.

Qin Feng, a very normal Biologist with some interest in xianxia books and video games, ends up as the Cleaning Lady(against his will) for the E.N.D. During a video game tournament, the massive earthquake "The Big One" hit, but the destruction did not occur, but a tear in the sky arrived. Within it came the massive waves of one-eyes creatures who took over the world and became the single governing body. Its head was known as "Death" Meeting new friends that came from another world, Qin Feng and friends set out to go from floor 80 down to floor 1 and escape the E.N.D.  The more they go down, the more the harder the challenges get. Will the cleaning lady Qin Feng manage to escape or will they be stuck with blue and white collar jobs for the E.N.D.
