Refining in the kitchen… How should one put it?
Let's just say it was rather unique and funny at the same time.
The reason was simple. Ye Lingchen could not produce fire. He was not a superhuman, and could not procure a flame in his palm like in the movies. Therefore, Ye Lingchen thought of using the gas stove.
Although starting the fire with the stove was a little weird, it was simple and straightforward. By theory, it should work.
In fact, Ye Lingchen not only used a gas stove, he also used a cooking pot.
Ker-tuck!
The gas stove was set alight, just like one would when cooking. He then placed the cooking pot above the flame.
He thoroughly heated the empty pot until it started producing crackling sounds. Only then did Ye Lingchen placed the two pieces of jade in the pot.
