Felix didn't get baited into doing it.
He understood that he could only push the gate open from this side. That's because the gate was considered as a one-way dimensional door on the universe's side.
In other words, opening it from the side of the eternal kingdom was like pushing a door open from its back, brute forcing its bolts.
This was the reason a significant amount of celestial energy was required to assist with opening the gate from their side.
While it was much simpler to open it from Felix's side, he was told that it wouldn't be easy for him to hold it open for a few seconds.
This signified that Felix had to commit the moment he pushed it open.
So, he ignored the weird call from the other side and started working on creating a void portal, connecting the gate to his void nation.
