It was no harm for Sui Xiong to be sure that his soul had traveled. At least he could stop thinking about where his body was going.
Sui Xiong soon put down the matter of where his body was and got busy with other things.
In fact, he had a lot of things to do, but all of them were delayed because he wanted to find his body. Now that he was sure that it was not his body but his soul that had traveled, he could do something else.
The first thing he wanted to do was steel-making. Thanks to Palin and after decades of research, the technology of blast furnaces had gradually matured.
Palin was inspired by the fact that when wood burned in charcoal, the temperature was much higher, and so tried to calcine coal as well. Many mistakes had been made and countless time and materials had been wasted during the calcining process, but finally, Palin found some solutions.
He used graphite in the end, which burned at a much higher temperature than ordinary coal.
