Versatile Mage: Start with Teyvat

Lin Feng traveled through time and became a full-time mage. He originally thought he could cheat and become a magic god. He could punch the Archangel of the Holy City and kick the domineering emperor Leng Dayan. However, after traveling through sixteen years, I still haven't found the golden finger that is essential for time travellers. Although the magic awakens the summoning system, it does not have any special talents. It wasn't until he released the magic that Lin Feng realized what the golden finger was. After Lin Feng released the summoning magic, his body came directly to another world. Looking at the scene in front of me, the endless grassland, the breeze blowing, the grass swaying in the wind, like a green ocean. Especially the iconic big tree and stone statue, Lin Feng recognized it at a glance as the Feng Qidi in Genshin Impact. A few years later, facing Leng Dayan, Lin Feng just released the primary summoning magic, and a brown figure walked out. "The heavens are moving!"
