Indoors.
Jiang Ning pulled out a piece of red-hot charcoal.
According to his knowledge, red-hot charcoal has a temperature of about 700 degrees.
If it was in the blower furnace of an iron workshop, the temperature could even reach nine hundred to one thousand degrees.
In an environment full of oxygen, it could even reach over a thousand degrees.
That's also why ironworkers choose to use charcoal as fuel, because the temperature of this kind of fuel is extremely high.
After that, he picked up the red-hot charcoal with his bare hands.
"It's really not hot at all!" Looking at the charcoal in his hand that resembled a red date, a hint of surprise flashed in his eyes.
At this moment, the red-hot charcoal in his hand felt like warm jade to him.
There was only a faint warmth, with no sense of burning pain whatsoever.
After fiddling with the charcoal in his hand for a while, the temperature began to drop, and Jiang Ning's gaze returned to the stove in front of him.
