Bab 836: Cap 834: I like this special mission

I just watch the ritual being performed, a big pile of Crystal coins and a space element magic Crystal are used along with other materials, then the girls come in to help. 

They use their affinities with the element of space along with the Wizard named Edmund to create an illusory image of a door 3 meters high and 2 meters wide. 

I see this door becoming more and more realistic until it's no different from a real door, this whole ritual only took 15 minutes, and it was way faster than I expected. 

I look at the tired mage drinking a Mana potion before jumping to stand beside the door inside the magic circle, so he waits being. 

"What he is doing?" (I) 

"This port is just a receiver, in other words, it's just like a normal port, the tunnel that will connect with this port must be coming from a Permanent Teleportation Gate of another big city." (Nicole) 

"Then why did he sit there?" (I)
