Chapter 1543: The True Myriad Ant Demon Devouring Divine Technique

Francido was immediately shocked.

He had encountered this situation before and was even very familiar with it.

The situation of the Myriad Ant Demon Devouring Divine Technique's Internal Breath being swallowed and annihilated without any resistance was undoubtedly the power of the Exterminating Heart Technique.

The way Chu Nan dealt with the tens of thousands of fine Internal Breaths that invaded his body was clearly from the Exterminating Heart Technique!

As a member of the Declan royal family, Francido was naturally qualified to cultivate the Exterminating Heart Technique and knew enough about it.
