At the start of the Emperors Era, Dark Crow spent countless resources to create a home for Su Ru and her son from Immortal Emperor Min Ren. However, because Dark Crow felt guilty towards Su Ru, he never visited the Heaven's Edge's Su Clan again.
Around 1,000 years before the end of the Difficult Dao Era, Liu San Jian from Immortal Emperor Min Ren's Cleansing Incense Ancient Sect discovered few rumors about Emperor having living descendants. Liu San Jian chose his youngest disciple Tu Bu Yu to verify these rumors and find Min Ren's descendants, in order to find his Immortal Emperor Merit Laws.
Tu Bu Yu then spent many years traveling around the Mortal Emperor World. Eventually, Tu Bu Yu discovered the Heaven's Edge's Su Clan. The Clan had not had any Immortal Emperor Merit Laws, but they still agreed to help and send their prime descendant Su Yonghuang to the Cleansing Incense Ancient Sect.
Because Dark Crow felt guilty towards Su Ru and out of respect for her achievements and contributions, he made an exception in his rules and allowed Su Ru to pass over the Physique Scripture's Solar Immortal Physique Merit Law and the War God Formula to her and Min Ren's descendants.
- Every year on the Dragon Heads Raising Day the Su Clan hold a great honoring ceremony. This tradition was established by Su Ru, and was performed ever since for millions of years. However, Su Ru had not revealed what exactly is honored - it is the day Min Ren was born.
