He Song had thus gained sufficient understanding of the Art of Taiyin Puppetry.
As for He Song, the Puppet Refining Skill was not unfamiliar to him.
When he was at the Foundation Establishment Realm, he had acquired the Spirit Puppet Skill, and he personally crafted many spirit puppets.
Some of these puppets were made from the corpses of cultivators, while others were crafted from materials he purchased himself, using precious materials.
Regrettably, there was no continuation to that Spirit Puppet Skill, and He Song eventually had to discard it as useless.
Even the puppets he had made back then had been collecting dust in his storage bag for many years.
During this time, the only puppets He Song occasionally used were the Golden Armor Guards he had found in various Golden Elixir Cave Mansions.
These Golden Armor Guards, obtained from one Golden Elixir Cave Mansion after another, were not weak, their strength equivalent to the Foundation Establishment Great Perfection.
