[Genius protagonist, regret and remorse, no selfless saint, rampant demon beasts, technology-based martial arts]
Chen Lin was abandoned and forgotten in an orphanage for eleven years.
On the day of awakening, Chen Hao, the Chen family’s adopted son, awakens only the lowest rank, F.
Then the steward delivers the news: the biological son they had forgotten in the orphanage has awakened an SSS rank.
“...”
“Now you remember you have a son? Where were you before? I lost my family eleven years ago, when my parents abandoned me and left me an orphan!”
“...”
A year passes.
Everyone thinks Chen Lin is long dead, but he is still alive. At the elite competition, he stands against the Chen family.
He fights his adopted brother in the competition.
“...”
“The Blood Camp will follow Colonel Chen Lin and fight to the death to reclaim the Haigu Pass!”
What kind of useless protagonist is this written about?
The inexplicable biological father dislikes his biological son and prefers his adopted son. The biological son is envious, jealous and hates him. When he goes crazy, he cleans up the original family.
