Liu Yun was a kind person. He even secretly told Lu Li and Qian Huanhan some information about Patriarch Gu. According to Liu Yun, Patriarch Gu was a skilled craftsman and was very likely to become a master craftsman.
Unfortunately, his wife died an accidental death, which had destroyed Patriarch Gu. He could not recover from this depression and was in a dispirited state for hundreds of years. Finally, Patriarch Gu recovered. But then his only son died when exploring a place. Patriarch Gu was without offspring.
This struck him even worse. Patriarch Gu was always a strange person but this incident made him much more difficult. He rarely made contact with others in the sect. He would stay in his mansion by himself. Apart from the Chief, none of the other patriarchs was in good terms with Patriarch Gu.
Patriarch Gu was even harder on the disciples. He would scold and even punish anyone that he saw undisciplined. Once, he scolded Lady Dan for an hour.
