Traveling Through Time and Space, Comes with a Holy Lord Development System?

Shen Du, an urban white-collar worker who was tired of a hundred years of hasty life, died suddenly while working overtime. When he woke up, he stood in a pure white space, with twelve talismans suspended in front of him - fragments of power from the Holy Lord of another universe. The dog talisman can lead to immortality, the dragon talisman can explode and burn... His talisman has been detected by this world's means as being of the mortal level - the upper limit of cultivation and foundation building, the lowest level of the sect. No one knows that those twelve talismans do not belong to this world. No one even knows that there is a Holy Lord development system tied into his body - task release, spell unlocking, and skill reward. At the very bottom of the system task list, there is a line of tiny gray words: "When all twelve spells are unlocked, the host will no longer be the host."
