Yu Huashen came back after 10 days. He came with many craftsmen who dug out the mud puddle and built a formation outside of the Teleportation Formation.
Once some alien races teleported from the Deserted World, they would be entrapped by the formation and those guarding the formation would be alarmed.
Lu Li was still worried so he ordered to build another formation. With two layers of protection, he could have enough time to be alarmed even if someone as powerful as Human Sovereign Realm warriors rushed out from the Deserted World.
Once the warning was received, those guarding the exit at the small world of Green Dwarfs would destroy the tunnel immediately. They might not have a chance to be back at the Deserted World, but at least they could still have the Northern Desert intact.
The formations were finished. Lu Li asked Bai Leng to have some very loyal warriors of the Bai Family to guard here and asked all the others to leave.
