It is said that Shi Lei was trapped within the Lava Lake by the Thunder-Fire Flood Dragon. To escape this desperate predicament, he continuously absorbed Soul Crystals, even though it seemed entirely pointless in the short term. Yet, clinging to a sliver of hope for survival, Shi Lei persisted without a moment of slackness.

Within this Lava Lake, the purple light mark seemed to absorb a certain type of energy, which it then channeled through Shi Lei's body and meridians directly into him, performing a Grand Circulation much like one would cultivate. However, it did not use Shi Lei's Spiritual Energy and Spiritual Power as a medium, but rather his blood.
