I said I would turn back time

Lin Xing has the ability to turn back time.
Whenever his life is in danger, he will go back to the past.
After falling to death, he returned to 5 seconds ago.
Being hit by a falling object, he returned to 1 minute ago.
After being hit by a dump truck, he returned to 20 minutes ago.
Suddenly one day...he found himself back a year ago.
