An hour later.
Inside the palace, as Lin Baichuan formed his final Hand Seal, the mass of molten metal before him began to writhe at high speed. Countless profound Dao patterns flickered, emanating an astonishing might.
At last, a resonant hum rang out.
It completely transformed into a furnace.
This furnace resembled Lin Baichuan's Heaven and Earth Furnace somewhat, yet differed from it in several ways.
In fact, when Lin Baichuan had first designed it, he had indeed drawn upon the functions of the Heaven and Earth Furnace.
That was why they bore some resemblance.
Yet their cores were entirely different. The essence of the Heaven and Earth Furnace was devouring, swallowing and refining every kind of power, whereas this furnace purified, extracting only that profound energy.
That was the fundamental difference.
"Condense!"
With a lift of both hands, a flash of light glinted from Lin Baichuan's palms, and the furnace finally took shape.
Emitting a profound Dao Rhyme, it descended from midair.
The next instant, the furnace spun, erupting with an enigmatic Devouring Power.
This Devouring Power was exceedingly strange. It could not devour other spiritual energy of heaven and earth, only extract that profound energy—and it did so at an astonishing speed.
The energy that had originally been mixed into the spiritual energy of heaven and earth, so faint as to be nearly imperceptible, now converged like vast rivers and roaring seas before flowing into the furnace.
"Not bad... the speed is at least more than a thousand times faster than extracting it myself."
Glints of light immediately flashed in Lin Baichuan's eyes as he murmured, "Moreover, as time passes, the extraction speed will increase further. In theory, it can reach ten thousand times."
Ten thousand times—this was the limit of the furnace before him.
After all, this
