I Stacked 1 Billion Damage in the Tower

It is the age of Towers. Players who accepted the calling of the Tower now venture for a larger power. Alab, an orphan has started his journey. He dreams nothing but to witness what is at the top of the tower. He knows it would be a rough journey but will his preparations be enough to overcome the challenges of the Tower? Or will he be defeated by the roller-coaster trail of events? Watch Alab as he paves his way to the top. A player who while others are busy in search of SSS-grade skills, is in chase of F-grades - a rank that is known to be the weakest. Will fate have another story in store for him? And is F-rank really the weakest as humans assumed? Amidst these uncertainties, one thing is certain. Alab... HE IS A NECROMANCER... a forbidden one at that. WARNING!!!! The first Volume will entail the journey of the protagonist and his close friends in the Tutorial. As they had only entered the Tower, they are still naive and immature so expect the 1st Volume to contain so much drama as that would mold them into who they will become in the next Volume.
