The process of concocting the "Heavenly Moon Blood Marrow" is extremely complex, and Chen Yu dared not lose focus for even a moment.
Should he fail in concocting it, the loss would be heartbreaking even for Chen Yu.
Thus, he activated the array of his cave dwelling, aiming to avoid any disturbances.
Three days later.
Chen Yu tossed the Moon Spirit Ore Mother and Blood King Marrow into a large cauldron.
Whoosh!
With a wave of his hand, the Blood Crystal Flame emerged and coiled beneath the cauldron, emitting intense heat.
"The final step, refine it with True Fire Spirit Flame for forty-nine days!"
Chen Yu covered the ancient cauldron.
The Blood Crystal Flame had a flame spirit, so it could refine the concoction on its own.
Chen Yu moved to the side and began secluded cultivation, practicing the Heavenly Demon Secret Pattern Record.
