Numerous currents of yin energy and death qi converged on the mountain, gradually forming clusters of black qi vortexes.
Song Changping and Song Chang'an sat cross-legged within the qi vortexes, swallowing the clusters of qi with each breath.
Their skin first turned black, then green, constantly changing and churning.
After an unknown amount of time, the yin energy and death qi here had been completely devoured.
Under Song Changming's perception, two cold, brand-new living bodies were born!
The entire process was much smoother than Song Changming had anticipated.
Transforming a corpse puppet into an undead corpse was much easier than transforming a living person. His two elder brothers were well-suited to this technique.
Their future cultivation would be simple, requiring only the continuous absorption of yin energy and death qi, refining it for their practice.
"It's done!" Song Chang'an stood up abruptly, filled with excitement.
