Prehistoric: Start by Proving the First Law of Thermodynamics

Pangu opened the sky without relying on an axe. He wrote five proofs in chaos, and the four basic forces were torn apart from unity, and heaven and earth were born. After his death, his consciousness turned into the twelve ancestral witches of the Three Pure Ones, each specializing in a discipline and suppressing the prehistoric times. Taishang Laojun's alchemy is essentially a chemical reaction equation. The Immortal Killing Formation of Master Tongtian is a mathematical dead end that can never be falsified. The twelve ancestral witches each guard a basic science, from astronomy to quantum, from fluid mechanics to microbiology. They are not connected with each other and have their own respect. Emperor Jun led the demon clan to build the Heavenly Palace, not seeking to understand the heaven and earth, but only seeking to control it. The Lich War is the ultimate showdown between basic science and engineering applications. Nuwa made humans out of clay, that was gene editing. Fuxi created Bagua, which is a binary code. The Fengshen List is a reshuffling of academic resources. And Lu Heng, a junior student in the Department of Physics, traveled back in time before all of this happened. The Three Pure Ones have not yet been born, the Twelve Ancestral Witches are still gestating, and all laws are yet to be determined. He only has a head filled with four years of undergraduate knowledge - but he has something that no innate power in the world has: An interdisciplinary perspective. While all the great powers were guarding the island-like barriers of disciplines, Lu Heng knew that the real power was hidden at the interface between disciplines. Between physics and chemistry, between mathematics and physics, between biology and chemistry—— When all boundaries are opened, all dharmas become one. That is unified field theory. The journey to enlightenment begins with proving the first law of thermodynamics.
