Chapter 1486: Four Great Demon Kings

In front of Han Li, Blood Poison, and the others, Mu Qing and the other three Demon Kings discussed several matters in succession.

It involved things like "Profound Ghosts" and "Puppets," and they were actually training troops on a large scale, as if preparing to attack something.

However, what Han Li was most interested in was the "Underworld River Land" that these people mentioned from time to time.

When he first heard this place name, Han Li's heart moved, and the first thing he thought of was the Underworld Land of that year.

However, apart from mentioning this place name a few times, these people didn't say anything related to this place.

At this time, Han Li had already retreated to one side, secretly observing these Demon Kings.

To be honest, the ones he found most mysterious and unfathomable among the four Demon Kings were Six-Foot and the old monster Di Xue.

The cold, icy aura emitted from the former was strange, not containing a trace of life. If it weren't for seeing his speech and behavior without any abnormality, Han Li would have suspected that he was simply a dead object.
