“The so-called key refers to the path leading to the plane passage!”The principal patiently explained the basic experiment for this group of extremely talented seedlings.
“The plane we are in is a material plane, but the universe is vast. There are many unknown domains in many places. The physical laws and laws in those domains are completely different from those in the material plane. The creatures and basic materials inside have extremely high research value to our plane. Summoner alchemists can communicate with creatures from other planes through complex alchemy arrays. Through equivalent transactions, they can obtain the material resources of other planes and even the biological effects of creatures from other planes. Therefore, Summoner alchemists have always been a popular industry in the universe.”
