The "Millennial Ice Frog" is not a special spirit material produced in any particular secret realm or location; it can be found in any place with a perennial ice glacier, though the conditions for its birth are relatively harsh.
Millennial is a figurative term; in reality, it may not take that long, but indeed, it does require frog spirit beasts to be frozen into ice blocks, near a Beast King Realm ice attribute spirit beast, undergoing a long baptism to form.
The higher the quality level of the frog spirit beast and the Beast King, the longer the freezing time, the faster the formation of the "Millennial Ice Frog," and the higher the quality and level.
As soon as this Millennial Ice Frog was brought out, it stirred the surrounding ether, and even without the Eye of Omniscience and Omnipotence, Lin Guang was sure that its grade and level would not be low.
