As a weirdo, I like being a Kamen Rider

Having spent fifteen years in Japan, Lin Chen always thought he was just an ordinary Chinese transmigrator making a living in a convenience store.
Until he was attacked and nearly killed by an Orphnoch in a dark alley late at night, he awakened the power of the Tiger Orphnoch and bound himself to the ultimate evolution system, which was minimalist to the extreme.
Defeating monsters earns evolution points, which can only improve the three basic attributes of physique, agility, and spirit; only by evolving one's own form can one extend their lifespan.
So he transformed into 'Kamen Rider' to protect humanity.
