Some involved living creatures, some involved energy and others involved the interaction between different Daos. The experiments had produced countless results, many of which were eventually abandoned.
The baleful energy occupying the deeper levels was one of those remnants and Lin Mu's brows furrowed as he read Zhenyu's explanation.
