Fantasy World: the Nerd's Calling Journey

In real life, Lin Yu, a "nerd", accidentally broke into the "Fantasy World" because of a light blue butterfly. He was bound to the system and became a summoner, and started a fantasy adventure of summoning spirits with books. When he first entered the secret realm, he relied on his "nerd" hidden talent to unlock unique effects such as attribute superposition, quick skill learning, and high-star summoning. He started in the novice village Qinghe Village and fought side by side with the Shimmering Butterfly Spirit. After experiencing mud monster traps, arena counterattacks, and thunder abyss breakthroughs, he gradually grew into a top summoner. On the way, he met the passionate adventurer A Ming, the spirit enthusiast Xiaoya, and the lucky Zhao Kun. The four of them teamed up to enter the dungeon and fight the mutated spirits, forming a deep bond in life and death. As his spirit evolved and his skills were unlocked, Lin Yu gradually discovered the secrets behind the world, and his exploration of the truth about the world and the way home had just begun.
