Heaven's Tower (dropped)

Towers are an existence only found in novels, they bring about great change to life. Gifting power only dreamt of, making humans into godlike beings. As a solar eclipse came by, Max like many people stared up at the sky. As the moon fully blocked the sun many simply smiled. As the minutes passed, these smiles soon turned into frowns, and then into fear as the moon simply stood there unmoving. That's when the system appeared. [Congratulation's Humanity, your bodies have evolved enough to intake mana] [As such Earth will become part of "The Tower" and earthlings will be given the right to climb if they see fit] [Watch out though, even if Earth's one of the lowest it will still be crawling with monsters, and one last thing] [Have Fun] Just like that Max's world turned upside down. Climbing the tower, becoming stronger with each battle. Will he gain the power to control his fate and become a ranker of the tower, or will he die and simply become someone else's stepping stone?
