Meanwhile, Mei Mengzhen had already gathered all the ingredients for the self-heating pack. The materials included roasted diatomaceous earth, iron powder, aluminum powder, coke powder, activated charcoal, salt, quicklime, and sodium carbonate. She first processed them into a little pack in the Spatial Mall, then took out the finished self-heating pouch and grabbed a bowl from home—the kind with two layers. She put the self-heating pack in the bottom layer, added cold water, and placed a packet of instant noodles on top. Finally, she covered it and waited.
The heating process of the pack was a bit slow, and both Mei Mengzhen and Fan Tianyu started to think it was a failure. Just then, there was a delayed reaction from below. Hearing the noise, the two of them were amazed, "Hey, do you hear that sound?"
"I hear it. Let's wait a bit. I think it's about to start heating."
