Golden Core Bottleneck

Once the medicinal potency of the Eight Treasures Breaking Wall Pill within the Violet Sun Furnace had been stimulated to its utmost limit,

he could cast the pill-congealing art at any time and successfully refine the Eight Treasures Breaking Wall Pill.

He Song did not have to wait long.

Within the Violet Sun Furnace, the medicinal power of a great many spiritual herbs had, under He Song's control and with the passage of time, begun to slowly merge together.

As the various medicinal powers layered and fused together, the effects they could produce underwent an enormous transformation.

If the medicinal power extracted from these spiritual herbs had originally been no more than the glow of fireflies,

then after those powers had been layered and fused together,

their efficacy became like the brilliant moon in the heavens.

The art of alchemy

had always been a means of turning decay into magic.

It could maximize the medicinal power of all kinds of spiritual herbs.

Take the Eight Treasures Breaking Wall Pill He Song was refining now, for example.

Although the spiritual herbs required to refine the Eight Treasures Breaking Wall Pill were numerous and each was exceedingly precious,

if one simply swallowed those herbs whole, one after another, they likely would not improve one's cultivation by much.

But if, as He Song did,

one used the art of alchemy to completely stimulate the medicinal power of these precious spiritual herbs to the extreme and then congealed them into pills,

only then could they truly become a potent pill such as the Eight Treasures Breaking Wall Pill, whose medicinal power was strong enough to help cultivators break through the late Golden Core bottleneck.

Such pills were extraordinarily valuable in the cultivation world.

Naturally, they were worth far more than the spiritual herbs used
