Tang Lingwu was feeling dejected outside, but inside the lab, Tang Mudao and Zheng Fa were not faring much better.
Tang Mudao was sitting in front of the computer, looking at the image of the Golden Core product under the electron microscope.
Zheng Fa's style was a bit odd.
He stood to the side, gesticulating in the air—he was drawing those two Shielding Talismans, to prevent the Spiritual Energy of Rainbow Mountain from interfering with the electron microscope and computer.
To put it simply, he was casting a spell to buff the computer...
This was one of the biggest problems after the Golden Core period—the abundance of Spiritual Energy in Rainbow Mountain made it impossible to use various electronic devices, which was extremely inconvenient.
Nowadays, Zheng Fa refrained from using the Spirit Mountain Technique except when everyone was cultivating.
