This is a passage from a Chinese fantasy novel. I'll try to summarize it for you:

  The protagonist, 君无名 (Jūn Wú Míng), has transformed into a black dragon after absorbing some kind of powerful energy. He's confused and disoriented, unsure of how he became a dragon.

  A young man with green hair appears and tells him that he's now a member of the "魔龙" (Mó Lóng) tribe, which is a type of dragon clan. The young man explains that this transformation is natural for someone with 君无名's bloodline.

  As they converse, a large black snake awakens and begins to slither towards 君无名. The snake seems to be attracted to him, but when it tries to wrap itself around his body, 君无名 instinctively uses his dragon powers to blast the snake away.

  The snake looks up at 君无名 with a pitiful expression, which makes him feel uneasy and confused. He turns to the green-haired young man for answers, who simply laughs and says that this is all part of being a member of the 魔龙 tribe.

  Overall, this passage seems to be setting up a story about a protagonist who's undergone a transformation into a powerful creature, and must now navigate a new world with its own rules and mythology.
