Don't mention it, Li Pu has indeed heard of the mechanical summoning array.
It's a type of mechanical summoning array that can 100% summon mechanical summoning beasts.
Moreover, it can also improve the minimum rank of the summoning sigils.
Back then, Senior Sister Wang Nuonuo said that her D-grade Mighty Steel was summoned using a level 1 summoning sigil on the mechanical summoning array.
That level 1 summoning sigil with a "Guaranteed E~D-grade" turned into a "Guaranteed D-grade" with the help of the mechanical summoning array.
As for the mechanical summoning array at Xidu University, that's all he knows.
"Seems like you're quite informed."
"Actually, ours here is pretty similar."
Listening to his introduction, Xiu Lijia started to introduce the situation in the Imperial Capital.
The mechanical summoning array in the Imperial Capital is of even better quality.
