Experiment

The followers of the death god obtained great knowledge, knowledge that even the Fallen Dead Sun never had access to it. Since the creations of people of a lower region were always discarded as primitive he never had any hopes for the Book of Death to ever amount to much.

However, he was completely flabbergasted when his clone was not only capable of rapidly climbing through the cultivation ranks, he also achieved an incredible understanding of the Dao of Death.

Shi Situ's first encounter with Shen Bao ended miserably for him, even though he had him in a well and firm trap he managed to overturn the entire thing against him and beat him at his own game.

Later on they had met once more in the Poison God's Trial, and ended up dying to the plan of Shen Bao which he orchestrated while Dao Shen was used to devour the body of the failure.
