A Nascent Soul True Monarch can see through the dantian.
This is common knowledge he had already known in his previous life.
Therefore, he has never encountered a Nascent Soul True Monarch in this life until now.
However, now that he has formed a True Core, and the inner rings at the deepest layer of his dantian are almost merging with it, even he himself has to look very closely to spot them.
As for the Anomalous Fire, it's entirely reasonable for a Tier Three Pill Master of a True Core to coincidentally obtain an Anomalous Fire, which is not easily perceived by others. He should be able to keep this secret.
The only concern he has now is the Golden Core he has formed, especially the layer of the Celestial Net imprint on the Golden Core.
If a Nascent Soul True Monarch can see the state of his Golden Core, there is a possibility that he might be used as a guinea pig for research by the True Monarch.
