At this time, a mysterious man suddenly appeared at home and rescued Abao. Abao was afraid of this sudden visitor. It turned out that the man was Wendi (Pan Canliang). He revealed to Abao that Hua, who seemed to be a modest gentleman, had an unbearable past behind him, and threatened Abao that the purpose of his trip was to retaliate against Hua. The sudden truth and this uninvited guest made Abao physically and mentally exhausted; facing this series of changes and threats, can the blind Abao escape?
