When the demon wave had been completely extinguished, Red Thorn reluctantly gave up on a portion of Class 4 demon flesh which it couldn't digest for now.
These Class 4 demons' flesh and blood, which were equivalent to Platinum feys, had withering and scorching effects. Even Red Thorn wouldn't be able to endure the consumption process.
Back then, Red Thorn had merely used the ramets as storage to store these Class 4 demons' flesh to prevent them from being consumed by Class 3 demons, forming a threat on the battlefield. Red Thorn would then accept the ramets' tributes, allowing it to absorb the flesh and blood energy through the ramets.
When large numbers of ramets withered, the massive energy would be transferred to Red Thorn's ortet roots from the ramets. The massive amount of energy placed Red Thorn in an immediate hibernation state.
