The moment Li Shiming accepted the emergency rescue mission, he received temporary permission to use the Teleportation Formation.
Following the prompt, the four of them went to the Immortal Alliance's Teleportation Peak and found the Teleportation Formation on the mountain peak.
Li Shiming had done some research into Teleportation Formations. The Teleportation Formations he arranged could not achieve long-distance travel, and even when he was in Central Province, he had been unable to make a Teleportation Formation capable of cross-continent teleportation.
That left his Teleportation Formations usable only as short-range Space Movement, with no way to spread them throughout the Cultivation World.
When he saw the Teleportation Formation on Teleportation Peak, beneath the cover of formation spiritual light that other cultivators could not see through, he saw the operating principles of the Teleportation Formation.
"Hiss!" After he saw the operating principles of the Teleportation Formation clearly, he could not help drawing in a sharp breath.
No wonder what he had obtained was only temporary permission for the Teleportation Formation, usable just once because of the emergency rescue mission. It was because the energy consumption required to support the Teleportation Formation's operation was enormous.
Based on the energy consumption of the Teleportation Formation before him, he could guess that what this Teleportation Formation consumed was not ordinary energy, but Otherworldly Spirit Crystals.
What were Otherworldly Spirit Crystals? Li Shiming had killed three Free Great Powers and had only obtained six Otherworldly Spirit Crystals from Xie Gan Great Power.
If Otherworldly Spirit Crystals were used as the energy source, he could have arranged a Teleportation Formation long ago.
The bottleneck he had encountered in his previous research on Teleportation Formations had been precisely how to use limited energy to activate powerful spatial energy.
The four of them stepped onto the Teleportation Formation.
