Although the Copper Puppet Method's Blood-Burning Secret Art could refine copper, some copper inevitably went unabsorbed by the refined copper heart during the process. For example, once the copper reached its boiling point, some of it would vaporize. That portion would not be absorbed by the refined copper heart and would instead settle in the body, naturally causing metal poisoning over time.
But this drawback was no great problem for Li Xiao. He had an undying body, so even if he suffered metal poisoning, his metabolism could expel the harmful substances.
No matter how he looked at it, this cultivation method seemed tailor-made for him.
"Zhang Long, go to the storehouse and find Accountant Fang. Tell him I need a large amount of copper. I don't care how he gets it, but I want to see it tomorrow. The more, the better."
Li Xiao decided to practice the Copper Puppet Method first, though its name did not quite fit. While its original purpose was to refine copper ingots into puppets, he felt Copper Refining Technique was more appropriate.
Originality was dead anyway.
Li Xiao simply renamed the method Copper Refining Technique. Zombies and ghosts could not practice it, and living people would die of metal poisoning if they tried. He was the only one who could cultivate it, so the naming rights naturally belonged to him.
Once Zhang Long left to carry out his orders, he told Ghost Tiger to close the door, then returned to bed and began cultivating.
The first step of the Copper Refining Technique was to refine the copper within his body and form a refined copper heart.
This refined copper heart was essentially a core. Some of the copper he refined afterward would strengthen it, while the rest would be controlled as a puppet.
