After Being Broken up by the School Beauty, I Became the Strongest Swordsman

[High martial arts + single female protagonist + monster invasion + zombies doing evil + reborn sword god + decisive killing] At the last moment when the world was annihilated, Lin Xu was unexpectedly reborn and returned to the day when his powers were awakened. This year, he was 18 years old, a day when he was ridiculed by everyone. The so-called school beauty girlfriend turned around and left without hesitation the moment he detected a D-level superpower, leaving him alone, facing an overwhelming amount of ridicule. This should have been his worst day. But now, he is extremely excited! Because his twin D-level powers [Ice] and [Thunder] actually have good growth attributes! As long as you kill monsters or corpses, you can deduce different skills based on the opponent's characteristics! Moreover, in the last life, the supreme sword intention that he unexpectedly realized was also reborn with him! In the last life, because no one in the human race could break through to the legendary tenth level, they could only be swept away by the tenth-level ghost emperor and the tenth-level king beast! But this time, Lin Xu is bound to change this result! "Anyone who stands in my way shall be punished!" "Anyone who stands in the way of the human race must be destroyed!" "Every scum of the foreign race will be destroyed by my sword!"
