Zhang Ruotong appeared, unexpectedly before the "Divine Calculation" of the Heavenly Number Mysterious Sect, which left people somewhat surprised and with many more questions they wanted to understand and know.
As it turned out, Zhang Ruotong was not the biological granddaughter of Zhang Yide, but a baby girl abandoned and found by Zhang Yide while traversing the Ancient Martial World twenty years ago. Although the Divine Calculation had been in seclusion, he was not unaware of the outside world, and had sent the master of Tianshuang'er, who was also his disciple, to find Zhang Yide and tell him that the Divine Calculation wished to take Zhang Ruotong into the Heavenly Number Mysterious Sect. However, at that time, Zhang Yide did not want to send Zhang Ruotong to the Heavenly Number Mysterious Sect; he simply wanted her to live a peaceful life away from further strife, which would be a fitting tribute to her biological parents.
