The Scum Is Diligent 

Li Tian is of humble birth. He has no parents. No one knows where they went, or if they were dead. When Li Tian came to Xinfaxian, he was already independent. Xie Lan and Fan Wen asked him about his hometown, and they went to Li Tian's hometown to investigate Li Tian's parents. But, no one could answer them directly, since no one knew who are they. All they know is that the young Li Tian is a diligent and smart orphan and is also very kind. 

Xie Lan and Fan Wen, naturally, didn't hide this from Li Tian. Li Tian was very ashamed and nervous, thinking that their founder and shifu would scorn him. But, contrary to his expectations, Xie Lan and Fan Wen are very compassionate. They told him to treat them as his fathers, and the Xinfaxian Sect disciples as his siblings. He should also treat Xinfaxian as his home.
