Liu Yan kept thinking.
He carefully recalled the production of the substitute puppet in his mind. This method was indeed feasible.
Then, the only thing he lacked at the moment was Gold Secret Art.
His current Gold Talent was still not enough. He had to upgrade it to Gold Secret Art.
Upgrading to Gold Secret Art was difficult for ordinary people. They had to come into contact with a vast amount of metal elemental energy. They also needed to comprehend metal attribute treasures continuously.
Even if one were talented, one would still need to spend a long time to succeed.
Without talent, one would not successfully upgrade to Gold Secret Art for the rest of their life.
However, Liu Yan had the SSS-grade talent, Divine Extraction. it saved him a lot of trouble.
For Liu Yan, there were two shortcuts.
First, when he came into contact with a high-grade metal attribute treasure, he could directly obtain it through Divine Extraction.
