Queen Ai went ahead and mentioned all the voided contracts, which included his subordinates/slaves' contracts, his supremacy games platform contract, his Mariana Federation contract as their leader, and many other individual but nonimportant contracts.
Since Felix made sure that all signed contracts didn't have a death penalty after voiding them, Queen Ai didn't do anything to him after his return.
Honestly, she wouldn't do anything even if he broke such contracts since Lord Loki was her true owner and he had Felix protected.
In fact, before Felix even connected to the UVR, he requested that Queen Ai didn't announce his return to anyone.
At this moment, he had no interest in exposing his return to Lucifer or his enemies...He wanted to have the first jump on them even if he could take them on quite easily.
"What about major events?" Felix moved on, not too bothered by the lost contracts.
