After returning back to Ruvisq, Zuro immediately started to check what was wrong with the energy core. He took out the energy core and took it to his lab. Meanwhile, he arranged a place for Vorian and Alexis to stay until he figured out what was wrong with the core.
Alexis and Vorian went to their room and then rested there for the night. And they rested there for many more nights. During the day, they would visit the lab and try to help Zuro with anything that they could.
Zuro worked on the core and did several tests on the components of the core. It took him several days to find out exactly what had gone wrong at that time. And after finding that out, he happily went to see Vorian and Alexis who were waiting for him in his office.
As he had a smile on his face, which was not normal to see on Zuro, Alexis asked, "Is the progress better than earlier?"
