Wang Lin's eyes stared at the spirit beast. After the third blood symbol was imprinted on the spirit beast, the aura it gave off even terrified Wang Lin.
The beast's body trembled violently, and the red light inside its eyes became even stronger. The red light was so strong that it extended three inches from its eyes.
Wang Lin calmly looked at the beast. Although he looked calm, his eyes were flickering. The jade with instructions on releasing the seals on the beast talked about this before.
A majority of the power of the God Slaying War Chariot was in the spirit beast. Every one of the seven origin soul blood seals could stimulate the beast to evolve.
If the seals were not released when that simulation reached its peak, then the spirit beast would explode and die. However, if the seal was released early, the beast's evolution would be interrupted and it wouldn't be able to reach its peak power in the future.
