I, the Anime Character, Fight Back in the Third Dimension

Fun version: In 2105, "300 Heroes", which was so unpopular that it almost died, was revived again. This time, it is no longer a traditional MOBA game with a hodgepodge of anime, but a large open world combined with virtual reality. What, there is a Yangcun here? What, can I transform into a Kamen Rider in this? What, how can you find the Divine Light Rod? Seeing the animation scenes from the old era revived in the game, everyone expressed their opinions - Ye Qing is back! Serious version: My name is Ye Qianxun, an ordinary tall boy with a boring life. Suddenly one day, something changed in my world. Something unknown is stirring in the darkness. In order to survive, in order to keep my world barely in its original state, I learned to breathe water, I transformed into Yajituo, I lived in symbiosis with the parasitic beast... I fought back in the third dimension.
