Doraemon: Become a Guardian Spirit at the Beginning

Lin Yun traveled to the world of Doraemon and became a fair-skinned and beautiful big sister... Wait, why a big sister? I am a man! Although my name sounds like a girl, I am a real man. Just when he was wondering, the system woke up. In order to integrate the power, she fell into a deep sleep. As a result, when she woke up, she saw a lot of people pointing guns at her. No, it should be the fat blue man next to her! She actually came to the special birthday episode of Doraemon's Long Day at the beginning and it was near the end, but it seemed that for her own reasons, Dai Jiaen didn't take the initiative to say that he was a wolf prisoner, causing Fatty Blue to be arrested soon. Can she bear this? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
