Even though Di Jiu had the Lattice Spiritual Elixir, the numerous cultivators of the Thunder Court Immortal Continent were frantically using his Confinement Killing Immortal Array to kill the demon beasts in batches. Di Jiu felt his Spiritual Sea becoming more and more painful.
Despite how impressive the Lattice Spiritual Elixir was, it was only a restoration elixir and contained 30% poison. Thus, when Di Jiu refined the Lattice Spiritual Elixir, no matter how high the purification was, he would still be unable to avoid the slight toxicity of the Lattice Spiritual Elixir. Besides, the Lattice Spiritual Elixir was not an elixir pill meant to purely restore Spiritual Force. It could also strengthen the Spiritual Force as well as restore the Spiritual Sea.
