Great Tang: Becoming an Immortal from This Era Onward

Lin Mo is reborn in the Tang dynasty, with an equivalent-exchange law from the start: any object can be broken down into energy, then that energy can be used to shape anything. He uses it to create the Twelve Talismans, nine masks, and the powers of the eight great demons. What would happen if technology like phones and computers appeared in ancient times? (That part will appear after Chapter 69.)

Back in the modern era, you called me a nobody, and I let it slide.

But now I’m in the Tang dynasty, and I have everything I need. What should you call me now?

Answer me!!!

(My imagination is limited, so some parts of the plot may not be handled very well.)
