The surface of the mountain at the peak started melting.
It looked like a giant candle, except that there is no wick. It started melting and the molten rock and soil which is very dense started flowing down. But after it reached a few feet, it started morphing into something.
The molten rock turned into a bird.
It looked like a raven and after it morphed into the shape, it immediately took off. Sam was surprised by the size of it. It is just a little bigger than an actual raven. It is not gigantic.
But it held so much energy.
He activated his energy vision to check and Sam felt like he was woken up by a slap in his face. The lump of molten rock held more vitality than a thousand year old tree and it is burning that vitality with that fire to transform it into energy.
This small lump slipped past the skeletons that are fighting the cultivators and the formations to go straight for a cultivator who is almost exhausted.
