This was an area-of-effect technique Chen Yi had devised after fighting Simon.
The reason it was high temperature rather than burning—
Was because burning had a drawback: it required time.
At Chen Yi's level, he could attach the concept of burning to anything tangible or intangible.
For example, light, gravity, gas...
Things that theoretically could not burn would still ignite like firewood beneath Chen Yi's flames.
