Intensely fervent emotions could grant those under the Eye of Life's attention an additional, temporary Life Force. This Life Force would fade away along with the fervour that spawned it. However, if the fervour was strong enough, that part of the temporary Life Force would also grow stronger, turning the individual experiencing the fervent outburst into a true cockroach of immortality.
However, with Zheng Yichen's current understanding of power, he knew that this immortality was relative. The temporary Life Force brought about by fervent emotions could act like true Life Force on the individual, but could not be applied to others or distributed further.
Additionally, this temporary Life Force was not truly Life Force. It could heal injuries, and no extra cost would be incurred after the fervour dissipated, but because it wasn't true Life Force, it might not always be exempt from death attacks.
