As he read, Huo Hai could not help but sigh. Whoever had researched this Puppet Secret Art could definitely rival the mad scientists of his previous life. Heaven knew how many people had been used for experiments in order to study this secret art.
The fine threads inside the Spatial Ring had actually been forged through special methods and could substitute for Spirit Veins. The greatest material consumption in puppet-making was almost entirely spent on these threads. Once the main Spirit Veins were damaged, these threads had to be used for repairs, and the results were not as good as the original. That was why intact corpses were so important.

Huo Hai discovered that if this secret method were separated out, he could try incorporating it into his Insect Refining Formation. Perhaps in the future, he would be able to control his own Spirit Insects with greater precision and freedom, while also reducing the threat of backlash.
