Humans can spontaneously combust.
Modern science does not offer a definitive explanation for human combustion, as it seems more like a phenomenon beyond common understanding. Modern science tends to attribute it to proximity to fire sources.
Fang La was nowhere near a fire source, yet he burst into flames as if combusting spontaneously.
Shen Yue glanced over and was left utterly stunned.
Fang La remained eerily calm amidst the flames, which suggested he had already foreseen his fiery transformation.
This was undoubtedly another form of high technology devised by the people of Mount Tianzhu, as during Fang La's combustion, the images surfacing in Shen Yue's mind showed that—those people of Mount Tianzhu were actually cheering!
It wasn't cruelty, but the jubilance of witnessing experimental success.
