Countdown to Doomsday, My Crazy Skill Proficiency

On the first day of his 23rd year, Bai Yu noticed that a countdown appeared on everyone's heads. After a simple observation experiment, Bai Yu immediately understood that these countdowns were life countdowns. But these are nothing. What is really scary is that more than half of the countdowns Bai Yu saw were concentrated on one day, and this time happened to be a whole year. This shows that in one year, there will be an apocalypse that affects more than half of the world's population. Biohazard, extreme weather, meteorites hitting the earth, or alien invasion? There are no precise answers to any of this. What makes Bai Yu even more anxious is that his only relative, his father, does not seem to be among the lucky few. At this moment, Bai Yu got a skill proficiency panel, and the skills recorded on the panel could be concretely improved in proficiency. Therefore, Bai Yu embarked on a path that is unimaginable to ordinary people until the end. However, this doomsday seems to be different from what we thought at the beginning!
