Genshin Impact: The Abyss Invades, and I Can Simulate Abyssal Monsters

[Foreign invasion + urban fantasy + spiritual qi revival + no female lead + comedic daily life + hot-blooded action.] In 2020, the Genshin Impact world's Abyss invaded reality. Countless monsters poured onto Earth, and Teyvat was devastated. Fortunately, humanity gained the protection of the Seven, and people began awakening their Visions to fight back against the monsters. "Don't think you can get away!" The heir to Venti's power spread his hands, and tens of thousands of Hilichurls were swept into the eye of a hurricane! "Planet Befall!" The heir to Zhongli's power folded his arms as a meteor several kilometers across fell from the sky! "No thought, no escape!" The heir to the Raiden Shogun's power drew a blade from his chest, and Musoujin Gorge formed once more! After an unexpected turn of events, the protagonist, Liu Dong, obtained a monster simulator. It let him enter a virtual online world and gain the attributes of monsters by simulating them, growing stronger and stronger: Slimes, Hilichurls, Whopperflowers, Stormterror, the Wolf of the North... Witness how humanity resists the Abyss invasion, and how Liu Dong saves the world. The early story follows humanity. Later, he enters Teyvat and begins the Genshin Impact storyline.
