Chapter 3170: Li Yao's Qilin Arm

Seeing the doodles on the ballpoint pens and pens, Li Yao's heart was beating fast. He had to cover his chest with his hands to suppress the familiar yet weird feeling in his heart.

Flipping to the back, there were also some sketches of 'magical equipment'. Most of them were chainswords, vibration sabers, and storm bolters. Not only did they look decent, they were also uniform and harmonious. One could tell that they were of a mature industrial design style that was completely different from the common designs. Moreover, there were also very delicate internal structures that looked like intricate, detailed circuit boards.

That was even weirder.

Li Yao majored in economics. He was very sure that he had never taken any courses in industrial design or circuit design. If the previous 'novel scenes' were just graffiti, what were the delicate and rigorous structural designs about?

Li Yao tilted his head and thought for a long time.
