The Nascent Soul Tree Demon was killed by Feng Jun, but the remains he dragged back to the Earth Realm were still Nascent Soul Materials.
Nascent Soul Materials are, of course, very precious. Even in the Kunhao Realm, cultivators would fight fiercely to obtain them, let alone during the declining era of the Earth Realm. The massive spiritual energy contained in the materials unsurprisingly alarmed the presence above the Alxa League.
Previously, Feng Jun had dragged back the remains of the Redwood Essence, but it didn't alarm such a presence at that time.
It wasn't until he returned from the void, with the leakage of Void Breath, that this presence was awakened.
The mysterious presence instantly scanned the Sahara Desert, "Oh, it's this little friend again, but this bit of Nascent Soul Spiritual Energy is like a drop in the ocean. Reviving spiritual energy can't be done like this... Oh, this is somewhat interesting?"
