시즌 1, 에피소드 5: Though PAK-NIN claims that it's impossible to search for the suspect CHAN CHIT-WO among the Dragon Gang, CHUEN-KUNG believes those who have been exposed to explosives for a long time must show a variety of abnormal symptoms. Field Officer CHOI follows CHI-SIN and discovers that he has several symptoms which seem to be identical to those, which, according to CHUEN-KUNG, might appear on the body of CHAN CHIT-WO. Prince TUEN surmises that the reason why the Phecda Bureau is able to solve the case is because they stole the log. Nonetheless, the Emperor decides not to blame those of the Phecda Bureau anymore as they have atoned for their errors. Suspecting that CHI-SIN is not the only one involved in the case, CHEUNG-SING and CHUEN-KUNG cannot help worrying about the Emperor's safety, so they dash to the venue where their Emperor and the Jin Emperor sign the treaty.
