Ghost Dragon of Cold Mountain

A Prince of the Song Dynasty is going to shave his head and pray for the people. At the tonsure ceremony, the abbot who performs the ritual attempts to assassinate the Prince, but is thwarted by the Field officers of the Phecda Bureau, YEUNG MAU, NGAU TAI-LIK and MA CHUEN-KUNG, in the nick of time. The leader of the Phecda Bureau, FUNG NAM-TIN, leads his troops and tries to enter the ceremony venue, but is hindered. Showing the badge given by the Emperor, NAM-TIN states that the Phecda Bureau is under the Emperor's immediate supervision. Following a prisoner SOU FU's escape, Commander SHE PAK-NIN analyzes the reason and tells NAM-TIN about it.

As SOU FU's case is successfully drawing to a close, CHUEN-KUNG asks CHEUNG-SING to go back to the Phecda Bureau together with them. Upon their return to Bianjing, CHUEN-KUNG spots a bridal sedan passing by, knowing that Minister HO, under the Emperor's decree, is going to marry off his daughter outside of the town. As soon as CHEUNG-SING enters the Phecda Bureau, his childhood best friend, PAK-NIN, hops out to challenge him. Apart from reprimanding CHEUNG-SING for not showing any repentance, NAM-TIN also wants CHEUNG-SING to resume his duty as the Commander, but CHEUNG-SING refuses to do so.

Having gone through an investigation, PAK-NIN deduces that it could be a fallen meteor. However, the fallen meteor is regarded as an omen, NAM-TIN feels very annoyed as he has no idea how to report this to the Emperor. CHEUNG-SING intends to let his wife TAO FA stay in the Phecda Bureau, unexpectedly, NAM-TIN requests TAO FA to move out. Later on, NAM-TIN meets up with TAO FA, handing her a key as well as a title deed and telling her to run the business of Peach Blossom Grove. After Minister YUEN is found dead and dumped outside of the Phecda Bureau, CHEUNG-SING goes to investigate it and learns that the late Minister YUEN often hung out at night.

Someone, who self-claims to have possessed the sulphur, goes to the Phecda Bureau to turn himself in, yet, PAK-NIN believes that he is just a scapegoat. CHEUNG-SING wants to meet HUNG FUNG but is rejected; whereas NAM-TIN also tells him that he has already instructed the Moon Section to look into the case. At the opening day of the Peach Blossom Grove, SAP-KAU delivers lavish gifts when TAO FA is distributing the flyers, and he even promises to stay there and help improve their business. CHEUNG-SING and his three fellow colleagues go to investigate at the Chaoyang Peak, where they uncover a cannon, so CHEUNG-SING suspects that the late Minister YUEN had a secret mission.

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.

With the Phecda Bureau finding out that it's KWAN CHIU who made the poison, CHUEN-KUNG and the others go to arrest KWAN CHIU and bring her to justice. KWAN CHIU bears a grudge against the Bureau after she is tortured during the interrogation, so she forces some civilians to swallow the poison. Finally, CHUEN-KUNG knocks her unconscious and sends her out of Bianjing. Constable KWAI-CHEUNG is attacked and suffers severe injuries, lapsing into a coma. He is rescued by PAK-NIN and his team who take him back to the Phecda Bureau. KWAI-CHEUNG turns out to be a spy, who penetrated into the Jin Dynasty and uncovered that there have been Jin moles in the Song Dynasty. Unfortunately, the confidential correspondence with a full log of details has vanished without a trace. CHEUNG-SING encounters his old acquaintance CHAU-YUET, who doesn't recognize him.

Disguising himself as a blind man, TAI-LIK brings along YEUNG MAU and requests to stay in Fa Yim Lau. Seeing that TAI-GAN gets suspicious, YEUNG MAU lies that they were actually sent there by SAP-KAU to pump for more information about Fa Yim Lau. In SAP-KAU's bath house, after TAI-LIK reports to CHEUNG-SING about what he got from his investigation, CHEUNG-SING surmises that HA LIN and another prostitute named KWAI-LAN must have something to do with the late SAU-KUK. Following KWAI-CHEUNG's sudden death, all of them comfort CHUEN-KUNG, telling him not to blame himself too much for this.

In the nick of time, YEUNG MAU saves TAI-LIK, who thus has a crush on her. Although KWAI-LAN admits that she bought the aphrodisiacs, she denies killing SAU-KUK. At that moment, there comes the news that HA LIN's dead body was found. Inadvertently, TAI-LIK spots YEUNG MAU's portrait and a love poem, so YEUNG MAU discloses that these were given to her by a client. TAI-LIK believes that the person must be a bad guy, but YEUNG MAU doesn't think so. After TAI-LIK learns of the past relationship between CHEUNG-SING and CHAU-YUET, he suggests that CHEUNG-SING should get close to CHAU-YUET. On the heels of her discovery of the empty cash box, TAO FA bursts into tears, complaining that CHEUNG-SING has spent all her hard earned money to help CHAU-YUET redeem herself out of prostitution.

CHEUNG-SING and his fellow co-workers successfully defeat the man in black and retrieve the confidential correspondence, which is recognized by the Emperor as a meritorious performance of the Phecda Bureau. Prince TUEN suggests setting up a special exam to select a martial champion, whereas CHEUNG-SING points out that Prince TUEN attempts to take this opportunity to recruit talent so as to contend against the Phecda Bureau.

Uncle KWA reveals that a man in black gave him some silver ingots last night, and WAN-LING guesses that the person is YAM MAN. All of the people regard YAM MAN as a real life immortal and even worship the Yam Rock. TAO FA notices her husband put on his Ninja suit, thinking he is YAM MAN. In order to help YUK-LAU, YEUNG MAU intends to sell her saber, but TAK-LIK, believing that she was deceived by YUK-LAU, tails after YUK-LAU. The Emperor enquires CHUEN-KUNG about things with regard to YAM MAN, CHUEN-KUNG suggests that the Emperor should go on an inspection in disguise so as to know the expectation of the people.

With CHEUNG-SING denying to be YAM MAN, PAK-NIN believes that it was a misunderstanding. Upon his return home, CHEUNG-SING sees that TAO FA is suffering from vomiting and diarrhoea. After CHUEN-KUNG is called on to check her pulse and confirms that she is pregnant, CHEUNG-SING is thrilled with joy. The Emperor arranges a Yam Banquet, which greatly aggravates the Empress Dowager, above which the Emperor even announces an immediate amnesty for YAM MAN. NAM-TIN frankly advises the Emperor that someone abused his position for his own gain and all the evidence points to Prince TUEN.

The Phecda Bureau is going to organize the Lonely Ghost Ceremony, which is also the big day when the Sun Section and the Moon Section compete for the Speedy Standard. However, TAO FA learns from CHEUNG-SING that he does not intend to participate in the Ceremony. Having been arranged to have a blind date with the Empress Dowager's nephew TAI HO-YAN, WAN-LING bursts into tears, stating that she does not want to get married yet, so SAP-KAU braves out for WAN-LING, revealing to the others that her wish is to join the Phecda Bureau.

Based on the distinct smell of an herb, WAN-LING gets a clue which leads to the murder suspect. CHUEN-KUNG indicates that the herb is called heartbreak grass and is a kind of poisonous plants that specifically grows in the mountain area of Jiangxi Province, but he has no idea at all as to what kind of connection there is between the murder suspect and YAT-SHAN. CHEUNG-SING, TAI-LIK, and YEUNG MAU disguise themselves as Taoists to perform the sacrificial ritual. All of a sudden, WAN-LING and SAP-KAU seem to be possessed by the ghost of the late Master TAI, accusing TAI HO-YAN of committing several crimes.

YAM MAN shows up as PAK-NIN is about to kill TAI-LIK. In order to clear the name of the Phecda Bureau, NAM-TIN orders all the constables to capture YAM MAN immediately. YAM MAN is stabbed and injured by TAI-LIK, and is even kicked off the cliff by CHEUNG-SING. Later on, when YEUNG MAU goes to the Ching Leung Monastery to pay tribute to YAM MAN, CHUEN-KUNG encourages her by using the words said by YAM MAN. Eventually, WAN-LING is allowed to join the Phecda Bureau.

TAO FA meets up with CHUEN-KUNG and the others, hoping that they will help coax CHEUNG-SING. However, CHUEN-KUNG frankly discloses that TAO FA will never have a baby because of her recent miscarriage. After the Yellow River bursts its bank resulting in countless casualties, the Emperor dispatches a court official, Judge SHEK, who is a man of integrity, to handle the issue. CHUEN-KUNG bids a farewell to Judge SHEK, during which they come across the Reverend Celestine, who tries to convince Judge SHEK not to travel far. As expected, Judge SHEK was struck by lightening and passed away in the middle of his journey.

CHEUNG-SING has drowned his sorrows in drink ever since TAO FA left, so SAP-KAU urges TAI-LIK to write a letter to TAO FA, trying to persuade her to come back. Reverend Celestine suggests doing a nationwide seven-day fasting so as to pray for the Song Dynasty. With CHUEN-KUNG casting a doubt on this suggestion, the Empress Dowager reprimands CHUEN-KUNG for disrespectfully contradicting the Emperor's guest, and even drives him away from the palace. The Emperor is still very energetic after fasting for three days. Frankly disclosing that a grievance arises among the people because of the fasting, Prince TUEN hopes that the Emperor could withdraw the decree of fasting. However, the Emperor totally ignores his advice, above which the Emperor even intends to confer the title of State Teacher on Reverend Celestine.

SAP-KAU, CHUEN-KUNG and YEUNG MAU accompany CHEUNG SING to Fa Yim Lau to probe into the matter. While there, SAP-KAU overhears that MEI-LEUNG, who bears the same resemblance to TAO FA, is the prostitute that Fa Yim Lau splashed out a huge amount of money on recruiting from Huizhou. CHEUNG-SING notices that TAI-LIK behaves strangely as he often came home late and his face lit up with joy, so SAP-KAU is concerned whether TAI-LIK has been seeing WAN-LING. TAI-LIK locates the whereabouts of Reverend Celestine's master, VANITAS, however, VANITAS has already been taken away by the time he reaches the monastery.

After the Emperor wakes up and finds out he is tied up, all of them try their best to expose Reverend Celestine's evil deception. Nevertheless, the Emperor adheres obstinately to his error, and even accuses the Phecda Bureau of attempting to overthrow him. Blaming CHEUNG-SING for offending the Emperor, PAK-NIN and his subordinates of the Moon Section tender their resignation. The Emperor sincerely believes what Reverend Celestine told him about the geomancy. He not only orders those court officials with certain animal zodiac signs that contradict him to wait outside of the hall each time he holds the court, but also banishes those who were born in the year of horse to the borderland.

WAN-LING frankly admits that she has fallen in love with CHUEN-KUNG although she once attempted to harm him. Having overheard this outside of the window, SAP-KAU cannot help but to feel disappointed. PAK-NIN returns to the Phecda Bureau to analyze Prince TUEN's machination together with CHEUNG-SING and CHUEN-KUNG, and CHEUNG-SING believes that Prince TUEN's purpose is to usurp the throne. CHEUNG-SING claims that he has already gotten a solid grasp of the evidence, which can prove Reverend Celestine is a rogue.

Thinking himself such a looser, the Emperor is unable to face CHUEN-KUNG again, but CHUEN-KUNG eventually manages to help the Emperor get the thing off his chest. CHEUNG-SING thinks that he can step down as NAM-TIN has returned, to his surprise, NAM-TIN tells him to continue to assist the Emperor and orders his subordinates to follow CHEUNG-SING's instruction as usual. The Emperor is concerned that the Empress Dowager might want to dethrone him, so NAM-TIN proposes arranging a trusted subordinate to stay by the side of the Empress Dowager as someone on the inside to help them.

CHUEN-KUNG runs into TAI-LIK and his wife when he is driven away by the government officers. NAM-TIN advises the Emperor to deploy the capital guardians to the northwest part of the country. With four senior members of Dragon Gang rescuing the court officials overnight, TAI-LIK and his wife, and SAP-KAU are all so touched by the move of HUNG FUNG that they all decide to join them. Once again, CHUEN-KUNG meets up with Prince TUEN, together with whom he bumps into TAI-LIK and the others in a secret tunnel.
