The bedroom on the second floor was engulfed in darkness, all the curtains drawn by Tang Qi. The disturbances that followed his last breakthrough left a deep impression on him, making it necessary to seal off the room even during the day to maintain concealment.
However, he did not immediately enter a state of meditation, as doubts were swirling in the depths of his heart.
His gaze fixed on the "Fresh Red Heart" in his palm.
The attached Information Fragments clearly told Tang Qi that it was a High Order Artifact of great significance.
Most importantly, it was also a fuel, a second type of fuel besides those Resentful Souls and Ghosts.
But Tang Qi clearly remembered that when he acquired the Sheepskin Scroll detailing the "Golden Furnace Meditation", the Spell on it declared: The Sun is the golden melter, the sole fuel is the soul.
Afterward, Tang Qi practiced the Meditation Method.
He ensured that the fuel added to his own "Melter" adhered to this Spell.
