Mortals Cultivating Immortality: I Have a Place Hidden in the Sea and Cave in the Sky

[Mortal flow + no system + decisive killing + step by step strategy] Lu Chuan was born with pseudo-spiritual roots of the fourth line. He even worked as a hard worker at the lowest level in the world of immortality and was persuaded to quit. However, his cousin detected dual spiritual roots and directly entered the inner sect. Until he obtained a [Hidden Sea Pearl] that could automatically purify water aura and transform into a portable water palace, and fell into his Dantian. From then on, the evil cold poisons of the endless ocean, the secret treasures of the deep sea, the great monsters of the aquatic tribe, and the alchemy of water methods all became excellent materials for his practice. Lu Chuan painted spiritual talismans, explored the relics palace, cultivated sword canons, and controlled sea monsters. With his pseudo-spiritual roots, he could still break through the stormy waves and become an immortal and an ancestor in this boundless immortal sea!
