From the Start: The System Transmigrated Me to Genshin Impact

In the distant past, the ancient god Pangu died while opening up chaos, and his body became the myriad worlds. Purusha was cut apart to nourish the universe, while Ymir's brain became the clouds in the sky. Ages passed, and civilization arose in a universe later known as Teyvat. At the time, Teyvat was ruled by the Seven Dragon Lords. Then Phanes, the Primordial One, descended and established Celestia as a base, creating four avatars: Life, Death, Time, and Space, the Sustainers of Heavenly Principles. They were Cecilia, the Life Archon; Youlandelle, the Death Archon; Istaroth, the Time Archon; and Asmodeus, the Space Archon. Later, Phanes used the primordial Eggshell that existed at the world's beginning to separate Teyvat from the starry sky. Lin Muchen was a teacher on Blue Star. One day, while playing Genshin Impact, he was taken by the System and transmigrated to Teyvat. But the unreliable System sent him back 10,000 years too early, when the war of the Second Throne was drawing to a close. The System then rewarded him with power on par with Phanes before falling into a deep slumber. Watch as Lin Muchen witnesses it all across time.
