In such deep waters, Ling Han had no worry about the possibility that Ji Wuming could find him.
Ji Wuming's battle prowess was indeed strong, but in terms of pure defense, Ling Han could guarantee that he was definitely the strongest of this cultivation level. Even Ji Wuming could only admit his inferiority—even if he was a Ninth Heaven Celestial King in his last life.
However, this was very, very, very boring.
Ling Han was the only one here, and not only was the scenery eternally unchanging, there was not the slightest bit of sound, making this seem like a living hell.
Fortunately, Ling Han could still enter into the Black Tower, where the four women could provide him some company inside.
Another 300 years had passed, and the number of indigo grade Yang Soul Stones that Ling Han had gathered had increased. The number was more or less 200, but he did not have a single purple grade Yang Soul Stone.
