"Well, I'll trust you for the time being." Power Star nodded slightly. In fact, he seemed to have no other way but to trust Jacob.
Jacob nodded. He turned around and threw the stone in his hand into the furnace.
That medicine furnace was made of composite material. It was particularly resistant to high temperatures, and it could reach temperatures that were equivalent to that of the surface of the sun, which could be endured by the outside. Moreover, it could completely isolate the high temperature from the inside of the furnace, so there was no need to worry about any bad consequences.
At first, Jacob didn't raise the temperature to the highest level, but under the low temperature, there seemed to be no effect on the stone. Through the screen, he could clearly see that the stone was still intact.
"How is it? Can't you increase the temperature?" Power Star asked nervously.
