My name's Rin, and I've been reborn as a cultivator with a broken core. Time to Save the World. Thankfully, the spirit who reincarnated me modified my core with a rune of power. Now, each time I ascend to a higher level, I can add a new rune, enhancing my strength. But this gift was given with a condition: If I don’t climb and conquer the Towers of Acalia, this new world will fall into ruin. Plenty of obstacles stand in my way. Raging Spirit Beasts. Tower summoned monsters. Rival cultivators. But by bonding myself to gorgeous women warriors, I can ascend and grow strong enough to take on the seven towers. Gods help anyone who stands in my way.
