If I Failed the College Entrance Examination, Why Would Bureau 749 Take Me In?

[Invincible Protagonist] [Decisive Killing] [No Female Protagonist] [Original Contained Object] Lin Lan traveled to Blue Star and awakened the anomaly containment system, which can contain anomalies infinitely and keep getting stronger! But this system needs to live until the age of 18 to be activated. On his 18th birthday, in the college entrance examination room, something unusual wanted to kill him! You want my life? I still want your life! No, why do you, Bureau 749, take me in? Since then, Bureau 749 has had one more special person. "Take in [Demon Sword Muramasa], acquire supreme sword skills, and kill everything!" "Contain the [Mirror of Fantasy], obtain the fantasy space, and accelerate time!" "Contain the [Snake of Baling], gain the power to push mountains, and open the sky with one punch!" Bureau 749: How come you become an S-class personnel once you contain an object? Lin Lan: I can't come? No matter what he does, just accept it and that's it!
