However, Lin Ke also discovered that the Gu Insect was not entirely without benefits.
His senior sister had suffered considerable bodily damage in the battle just now, with ruptures in her meridians throughout her body.
Under normal circumstances, the spiritual energy inside her would already have scattered and been rampaging everywhere.
Her injuries would have been far worse than they were now.
But because the Gu Insect needed to circulate an entire cultivation technique within her body to feed on spiritual energy,
it had actually taken the initiative to form channels of witch Gu power that isolated the spiritual energy, replacing the meridians' function within her body.
And because the Gu Insect absorbed spiritual energy, all the energy that had scattered into his senior sister's body had been absorbed as well, rather than rampaging unchecked and worsening her injuries.
Thus, in a certain sense, this Gu Insect had actually kept his senior sister alive.
Forcibly removing it before her injuries healed might endanger her life.
But by the time her body healed, the Gu Insect would already have taken control of it, leaving her no possibility of ever breaking free.
At least, no one outside the Illusionless Gu Sect knew a solution.
He circulated his Spirit Power again to examine his senior sister's body and discovered cracks in several of her bones.
The wound on her back was also riddled with all sorts of wood splinters and fragments.
Having examined her this far, Lin Ke had no choice but to cut away all his senior sister's clothing, exposing the wound at her waist.
He used his own Spirit Power to force out the wood splinters one by one, then let the Power of Thunder scour the wound.
He then sutured the wound closed and applied healing cultivation pills over it.
