Came to Teyvat with a Substitute

In a dark alley, Mo Yu picked up a strange arrow and was accidentally stabbed by the arrow after taking it home. With a flash of golden light, Mo Yu found that he had brought the arrow to the continent in the game he was playing recently - Teyvat. Mo Yu calmly used his knowledge of the Teyvat continent to gain a foothold in Liyue, but during an attack by the Qiuqiu people, he discovered a power that he seemed to have had but had never discovered when he came to this world - a substitute.
