Well it will be more standing out if somehow his power make too many people shocked(and you know as usual op mc doesn't know how restrain), So visiting the king ahead is actually not that bad.
You can see what the king condition and mentality when dealing with the king first(threaten the king is also possible if the king is suck).
Also can make sure you not going to be more standout if your disguise fall apart since you have the king to cover you.
The benefits is good enough to take the risk
But yeah some people really don't understand what not standout means
