Under the Star Gu's confinement, the Shadow-Binding Insect was soon placed atop the first Insect Refining Formation. Around it, quite a few Star Gu joined forces to seal the entire room. This was to prevent the Shadow-Binding Insect from escaping.
Although Huo Hai was using the Shadow-Binding Insect for experiments, it was ultimately an extraordinarily strange Spirit Insect. It had no body—or rather, its entire body was a shadow. A shadow condensed from a mass of dark power. Even Huo Hai himself could not say exactly what it was made of. If he let the Shadow-Binding Insect escape, he would not know where to look for it.
Huo Hai lightly pressed a finger against the Insect Refining Formation. This newly created Insect Refining Formation did not even need Spirit Stones embedded within it; he could activate it directly with his own spiritual power. Most Spirit Formations of the Celestial Star Sect could be used this way. This was not something ordinary people could accomplish.
On the Heavenly Spirit Continent, most Spirit Formations needed Crystal Cores or Spirit Stones embedded in them to function. Even the few special ones required other materials. To use no materials at all and rely entirely on one's own spiritual power as a substitute—
Apart from Spirit Formation Masters, probably only a handful of factions could achieve such a thing. The Celestial Star Sect was one of them. Likewise, while these Spirit Formations could use one's own spiritual power in place of materials, Huo Hai could still add Spirit Stones if he wished. But for such a simple Spirit Formation, there was no need to go through that trouble or waste Spirit Stones.
Once spiritual power flowed into it, the Spirit Formation quickly began to shine. As the light flickered, the Shadow-Binding Insect gradually calmed down.
