Even though the Realm of Monsters had abundant Spirit Qi and many Spirit Beasts, Spirit Fruits and Spirit Medicines, these weren't helpful for Chen Fan.
He had entered the Core Formation State and the amount of Spirit Qi he needed each day was comparable to that of a normal Golden Core Cultivator. Small worlds like Earth and small secret lands would be unable to be of much help.
"No wonder the Sky Immortals and True Gods left for other worlds. I can only rely on the power of the universe if I can't find a real cultivation planet," Chen Fan pondered.
Once he entered the Golden Core Level, he could get rid of the Spirit Qi and absorb much stronger energy, such as the power of the sun, Taiyin Qi and the energy of the planets. These types of energy couldn't be refined by a normal cultivator. Only Golden Core Cultivators could take them in with their highly concentrated True Essence.
