The next moment, the jade coffin emitted a glow and, astonishingly, lifted into the air by itself.
Then, a faint apparition that could be seen by the naked eye floated out from the jade coffin.
At first, the apparition was exceedingly tenuous, akin to a wisp of green smoke, as if a gust of wind could extinguish it. However, at this moment, a droplet of lustrous green marrow oozed from the coffin, falling onto the specter.
It was like casting a pebble into the calm surface of a lake.
The once fluttering apparition instantly became much more solidified, rapidly transforming into a human figure, with its facial features becoming much clearer.
It was unmistakably the Footprint Emperor.
The Willow God's expression turned to one of shock, somewhat surprised that the small jade coffin possessed such a heaven-defying ability to solidify the remnants of a thought at the Quasi-Immortal Emperor level.
