Whoosh, whoosh!
Liu Yu waved his hand lightly, and countless spirit stones instantly appeared in the room, piling into small mountains.
Spiritual light of every color flowed across the densely packed spirit stones. Even the lowest-quality ones were Mid-Grade Spirit Stones, and there were plenty of high-grade spirit stones among them.
Having cultivated to the Nascent Soul Realm, the meager spiritual energy contained in Low-Grade Spirit Stones was no more than a cup of water thrown onto a burning cartload of firewood to him.
Even filling the Cultivation Room, dozens of zhang across, with Low-Grade Spirit Stones would certainly not provide enough energy for his advancement, so there was naturally no point in taking them out.

Boom!!!
The fourth-tier Spirit Gathering Array activated, and the Cave Abode's floor trembled almost imperceptibly.
At that moment, all the spiritual energy on Heaven-Reaching Peak began rapidly converging on Liu Yu's Cave Abode.
Whoooosh~
Outside, winds rose and clouds surged. With Heaven-Reaching Peak at the center, the Heaven and Earth Spiritual Energy within a hundred-li radius was slowly drawn into motion.
Under the Spirit Gathering Array's influence, it flowed slowly toward Heaven-Reaching Peak.
Bang, bang, bang!
Inside the Cultivation Room, Liu Yu released strands of magic power as fine as hair. The mountains of spirit stones burst apart one after another, releasing vast quantities of spiritual energy that filled the room.
An enormous amount of spiritual energy appeared in an extremely short time. But the Spirit Gathering Array had already begun working, preventing it from naturally dispersing into areas of lower concentration, so it became visible to the naked eye.
Multicolored mist filled the spacious Cultivation Room,
