The Path to Immortality in the Other Sea Realm

The Othersea Realm is a vast plane, existing independently. Through Ye Qingshan, Lu Yuan learned of the Othersea Realm. With Pipi and the others by his side, he gradually embarked on the path of cultivation, defeating powerful enemies on Earth one step at a time. In the end, he journeyed to the Othersea Realm. As he grew, he also began to uncover secrets that had long been hidden... He discovered that the Othersea Realm was not only larger than the observable universe he knew, but also home to many cultivation systems: wizards skilled in magic; the elven race, whose soul power and telekinesis were formidable; the Voidbreakers, who excelled at spatial power; and the Illusion Demons, famed as the masters of illusions. Lu Yuan made many friends there and encountered many new enemies. He defeated one powerful foe after another and, through hard work, mastered many cultivation systems unique to other races. At last, he defeated the strongest and most evil enemy and reached the legendary realm.
