There was no point in remaining in the Measurement Center anymore as the only test left was his energy capacity.
Felix didn't need to test it as he already felt that his energy was almost half full after he finished replacement.
This suggested that his capacity had actually doubled as well!
Felix knew that this was a massive enhancement as the others rarely receive a 50% increase even after using a legendary bloodline.
Since energy was always his Acheel's Heel, he was most glad by this enhancement.

Back in real life...
Felix was dialing Looby, wanting to check whether he had his money for the old three serpents bottles or not.
15 days had passed since Looby received them, marking the end of the payment delay.
If Looby didn't come through and paid him now, Felix wouldn't hesitate to enter a non-exclusive contract with other shops and send them those four sand bottles, which were still in his possession.
