A Record of a Mortal's Journey to Immortality: I Reincarnated as Wen Tianren and Swore Brotherhood with Han Li

Modern-day young man Wen Tianren dies suddenly after staying up late to reread A Record of a Mortal's Journey to Immortality for the second time, then transmigrates into the novel's world as Wen Tianren, a disciple of Six Extremes Sage. Knowing that Han Li will be the strongest person below the Nascent Soul stage in the future, Wen Tianren deliberately tries to befriend him. When he encounters Han Li, he merely exchanges a few moves with him and avoids making an enemy of him. After a series of trials, the two become sworn brothers. Later, when enemies show up, he puts on a show of strength and face-slaps them at every turn. Together with his friend Han Li, he escapes from the master who slaughtered his entire clan: Six Extremes Sage. He falls in love with Ziling, and the two flaunt their affection as they become Daoist partners on the path of cultivation. He and Han Li are the best of brothers, sharing hardships and supporting each other as they journey toward immortality.
