Fusing the Space Rules with some basic rules is a prerequisite for breaking through from Eighth Layer to Ninth Layer, and at the Tenth Layer, one needs to fuse even more rules. Apart from the Rule of Time, other pillar rules can also be attempted for fusion.
For example, the Life and Death Samsara Rule, formed from the fusion of the pillar rules of life and death, has astonishing killing power, and no amount of Spatial Layers can block it.
Of course, whether it is the rule of life or the rule of death, both are pillar rules, and the fusion between pillar rules is by no means a simple matter.
Therefore, the strength of life at the Tenth Layer has no specific standard and is assessed solely based on the level of threat posed.
The major cosmic races use a unified standard to categorize the threat level of Tenth Layer life into six levels.
Grade A, Grade B, Grade C, Grade D, Grade E, and Grade F.
