Luo Xiaoxu was a well-known "Master" in his previous life, but he was framed by Lin Yuwei, a closed disciple, and eventually died tragically. Maybe God took pity on him and gave him a chance to come back.
In the previous life, Yun Tinglan, his least loved disciple, was the one who worried about him the most. After Luo Xiaoxu's death, Yun Tinglan relied on his superhuman wisdom and medical skills and was called the "Master". However, Lin Yuwei still did not repent and used the same method to kill Yun Tinglan. At the same time, Yun Tinglan from another world accidentally traveled into the novel he had just finished reading, "Reciprocity".
(Both of them are called masters and masters because they are cultivators of immortality.)
