Black and White Alien World

Yu Xiaotian is a young man who has graduated from college and is doing nothing. He has a very upright appearance and regular facial features. One day he stayed up until three o'clock in the morning, and when he just started to fall asleep, he unknowingly entered an unknown alien world. There, he relied on his experiences during the day to gain upgrades in the alien world. He could not completely exit the alien world until he reached the system budget level. Otherwise, the system will designate players after ten days, and players in other worlds after zero o'clock will be locked and unable to return to the normal world.
