Long Fangyu

Alex, the two elders, 20 Alchemists, 20 assistants, and the commander got onto the large teleportation formation that could easily fit 2000 people inside of it.

Alex was quite surprised at the size of the teleportation formations as most other continents had rather small formations that could take maybe 200 people at once. 

Alex could also see just how old the formation was from the slowly fading surface of where he was standing. It wouldn't be long before these people had to fix this formation, but since it was made up of metal, they were probably used to it.

Between Metal and Stone, Metal had the advantage of not having to worry about how the Qi was being delivered to it as it was capable of equally distributing all Qi it was given.

As such, the people could also fix it whenever it broke by just asking someone with the Metal dao for help. A person like that could quickly fix up the places where it was broken within an hour.
