"Episode plot introduction of 'Smart Detective B' and download for Smart Detective B"

Zi Leung is bold, while Yu Heng harbors resentment.

When Zi Leung became a father for the first time, he suffered from sleep deficiency at night due to taking care of his son, Yu Ga An. His boss, Lo Yu Heng, felt sympathetic towards him. Fortunately, Zi Leung timely praised Yu Heng's newly bought global positioning account book, which helped him out of the awkward situation.

During the investigation of a homicide case, Yu Heng believed that it was a suicide case, but Zi Leung had a different opinion. He even used Yu Heng's new account book for an experiment to prove his own speculation, causing the account book to be written off.
