Markus and the others are also present in the Teleportation system room. Sam already finished modifying the whole teleportation system and called everyone to introduce them to the new teleportation system.
Previously, Leon, David, and Marry were the ones who modified the teleportation system. But they did not know about this new teleportation system and even after observing the new teleportation system, they were unable to find out the features of this new teleportation system.
It is natural for them not to understand because Sam uses the advanced method that he gets from the system. Sam gives them some time to observe the teleportation system while he is recovering The lost energy.
Sometime later, he finally began to explain about the new teleportation system and he also told them that currently he needed to register the Spiritual energy of the Warriors of the Eden Blue.
