This could be recommended for the book " Dragon Blood Glory ". The protagonist, a rich young master, was framed and imprisoned. He accidentally obtained a 10,000-year-old magic bead and entered his body. From then on, he floated between the two worlds. Later on, he carried the Supreme Being's dragon blood and went through countless hardships. Could he look down on the heavens? In this story, the dragon blood could turn the protagonist into a dragon man, and there was also the deep master-disciple relationship between the master and the protagonist. I hope you like my recommendation.
