The Great Grandmaster of the Mysterious Dark Sect was quite old, but Tian Jinren was even older. According to Jing Jiu, Tian Jinren left the South Ocean over six hundred years ago to look for the inheritors of the Great Grandmaster, Nan Qiu, on the Foggy Island. Eventually, he selected Jian Xilai for Nan Qiu, so he should be at least seven hundred years old.
His talent in Cultivation was ordinary, but his mental strength was truly exceptional. His willpower had reached an extremely high level after cultivating for more than seven hundred years. Normally, he wouldn't have any equal in the world. Unfortunately, he was good at predicting the destiny of others, but failed to anticipate his own misfortune; he had encountered the likes of Jing Jiu and the Young Zen Master in Zhaoge City earlier, and met the likes of Yin San later.
