WU FAY, son of WU YAT TO, in order to escape his enemies, hid with uncle PING SI at Jade Peak villa for years. PING always asked FAY to practice the art of how to use the blade under the WU family's methods to take vengeance for his father. The art was hard to master because some of the records were missing. At the foot of the mountain, TO FIFTEEN, a man in disguise of FAY pursued by TIN KWAI LUNG, FAN HING TANG and their students, had reached the villa. LUNG and TANG threatened HEI MAN, the host of the villa to hand in TO. When FAY revealed his own identity to avoid the innocence being killed, MIU YAN FUNG appeared and resolved the difficulty for MAN.

FAY discovered a booklet in which TO had written a series of the family hatred over the century. In 1644, LORD CHONG was under siege at JIU GONG SHAN. Three warriors, i.e. MIU, FAN and TIN went to summon reinforcement. Another warrior, WU, stayed to take care of LORD CHONG. However, the situation had changed. WU had to pretend to be a traitor to avoid ill fate. However, without knowing WU's pretense, MIU and FAN killed WU. Afterwards, DAN, son of WU told MIU and FAN the misunderstanding. Both MIU and FAN felt guilty of killing WU. In a subsequent fight for saving LORD CHONG, both MIU and FAN were killed too. The misunderstanding among the three warriors were never revealed to their children and grandchildren. As a result, there were a series of killings in the following generations among the three families……

CHAU who was the cousin and fiancee of MAN had a bet with TO to compete to find a treasure. MAN, on the other hand, made use of CHAU’S intelligence to find out the actual location of the treasure. CHAU was sad for MAN’S hypocrisy.

FAY then, found the booklet left to him by TO in the cave. It described TAN and LUNG, leaded by FUNG, looking for TO to get even with him. FUNG, renowned for his name as "Wordl No. 1 without competition", lured TO for a fight. On his way, TO met SAI and helped him settle his big debt. TO treated SAI like a brother and SAI felt very grateful to TO. On the other hand, FUNG and TO became good friends during fight after knowing more of each other's characters. However, highly influcence by LUNG, FUNF decided to invite TO for a final fight.

After CHAU’S persuasion, TO was tempted to tell FUNG the resentment in details so as to put an end to the fuel. When TO wanted to tell the truth, TAN and LUNG attacked CHAU who was about to give birth to a child. TO hurried to protect her while SAI, who was wounded, went looking for KEI, the doctor to help. FUNG understood TO had just become a father and decided to postpone the duel. CHAU talked TO into writing a letter to explain to FUNG but it was being exchanged. On the day for the duel, CHAU persuaded TO to use a special tactic to attack FUNG’S weak point but was refused by TO. In order to avoid hurting FUNG, TO was wounded by FUNG's weapon which left black scar between TO's eye brows.

TO was poisoned to death. At once, LUNG and TAN together attacked CHAU who entrusted her son, FAI to the care of SAI.

NAN mercilessly gave up her daughter and eloped with LUNG. FUNG and his daughter had to rely upon each other for life.

FAY, in a moment of desperation, found out a way out of the trap. MRS SHANG, enraged with her failure, committed suicide by walking in the blaze. Becoming sworn brothers, SHAN gave FAY his white horse and some money and left first. BO, son of MRS SHANG, felt sorry for not able to take revenge for his mother. A girl named NIP SONG CHING, passing by while FAY was beating BO, stopped FAY and mistook him of stealing the horse. CHING was the cousin of SHAN. Being wrongly accused, FAY followed CHING so as to get his horse back. Meeting SHAN, CHING realized she had made a mistake.

FOK ON HONG was going to call for a fighting conference in order to stir up troubles. LOK, in order to prevent a catastrophe, contacted the BIG FOUR HEADS. CHING, on the other hand, volunteered to kill LUNG. It seemed there was great hatred between the two. LOK was infatuated with PRINCESS PERFUME while CHING was enchanted with LOK. In a restaurant, FAY ran across little guy, YAT, who enriched his experience by bringing him to travel from place to place. FAY marveled at his boldness. YAT led FAY to a banquet for heroes so as to eat and drink extravagantly. CHING, arriving at the banquet in the name of LUNG, was humiliated. CHING met FAY there and together, they went into a fight.

CHING, unable to match with FAY, teased YAT. While trying to help out YAT, FAY discovered YAT was actually a girl. YAT, a student of NIP YU FENG who was head of the SKY DRAGON SECT, was ordered by FENG to kill LUNG who was the black sheep of the sect. However, owing to YAT's limited capabilities, FENG could only teach her a few tricks to combat LUNG.

CHING defeated FAY and left. YAT again, in disguise as a guard cheated LUNG of LORD CHONG’S saber and gave it to FAY as a gift. LUNG could do nothing but watch YAT leave. With the help of the saber, FAY was able filled in what he had learned to highly increase his KUNG FU to a high level. FAY chased after LUNG who had retreated numerous times. However, CHING saved LUNG once again. FAY told her what was right and wrong but she went her own way.

HIN swore to die refusing to yield and took leave. YAT unveiled that the mysterious person was CHING. SHANG explained that what CHING did was a compensation for what she had done.

Surrounded and attacked by eighteen royal guards, LOK and his men were in great danger. Fortunately, YAT knew about their entrapment while she was on her way so she came to join them. SHAN and the others hurried to the rescue. FAY was seriously wounded while saving CHING. FAY even expressed his love to CHING who was overwhelmed.

HONG loved CHING at the first sight. HONG sweet talked CHING out of her hatred. CHING was moved. HONG let her go in order to re-catch her. On her way, CHING was confused and disturbed because HONG took care of everything for her and expressed his love for her. When she arrived at the headquarters of the RED FLOWER SOCIETY, YAT saw her revealing face and asked her endlessly to know who her lover was.

In the cave, SHAN cut HONG’S ring finger with his jade ring in order to exchange for the BLACK and WHITE GHOSTS. In order to save HONG, CHING had to hurt HIN and YU. They fled to an old temple where they had made love. In the following morning, FAY found them and seeing them try to leave, FAY fought with them. When the members of the RED FLOWER SOCIETY arrived, HONG managed to escape but CHING was expelled from the society.

YAT brought FAY to his home but he drank a lot and vent his anger by practising blade day and night. At last, he was too obsess in practising that he had in fact reduced his kung fu to the lowest level. FAY then left a letter and left in silence. One day, FAY was drunk at the TEMPLE of WATER and MOON, and fell unconscious. FENG and LAN passed by and found FAY in his conditions. With NAN serving beside, FENG used his internal power to heal FAY. In order not to let FAY know he had saved him, FENG left with LAN who gave FAY a grasshopper knitted by her with grass as a souvenir.

FAY handed FENG a letter not knowing it was part of LUNG’S conspiracy. FENG, however, mistakably blew the poisonous vapor into FAY’S eye. At that time, LUNG, leading his followers, surged to capture them. In chaos, YAT and FAY retreated to the backyard. LAN found YAT used a yellow handkerchief, given by LAN to FAY, to wrap FAY’S eyes. FAY fell at the bank of a river. LAN followed him and got on board a wrecked boat with him. Both fell into the water and were separated by the current. When they met again, FAY suddenly realized LAN was the benefactor who had saved him. However, he was not certain about LAN’S background.

LUNG ordered his men to capture LAN alive so as to threaten FENG to hand out the treasure map.

When they passed the bridge made by iron ropes and reached the PEAK, they saw a woodcutter working with all-out effort. YAT asked him for the direction but he was dumb and gave them the wrong direction. On their way to return, they saw the dumb taking a rest on the path and ate the fruit left by the dumb man as they were hungry. Then they suddenly felt itching. The dumb hinted them to eat the little white flowers to cure their itching.

ZHENG had been in the past accused by TO as a mean person and ZHENG always remembered his hatred to TO. The dumb, having saved the trio several times, was killed at last by ZHENG. Superficially, ZHENG was healing FAY, but he, in fact, was forcing the poison in FAY’S body to the SAN CAO veins where FAY would have no ways to cure his disease.

YAT knitted a grasshopper which had scarred her hands but FAY neglected what she did and always remembered NAN only.

FAY saved FENG who made NAN recognized the real side of LUNG’S personality. At the inn, FAY frankly told FENG the reason he had saved him was for repaying his saving him in the past but he still would take his vengeance against FENG. Hero knows hero. They appreciated their friendship. FENG promised to find out the person who poisoned TO within one year.

CHING had given up on herself to despair. NAN comforted her but CHING felt NAN’S love in her words. Giving FAY a miss, CHING left and met BO on her way. CHING had fainted for saving BO who then brought her home and took care of her. FAY chased her to BO CHUNG SECURITY HOUSE where he decided to stay until CHING changed her mind.

When the wedding of BO and CHING was in progress, YAT and LAN arrived and relieved to know that the groom was not FAY. The love between FAY and CHING ended. FAY rested his heart and laughed joyfully. YAT and LAN were happy to see this. CHING decided to forget the past and try to become a good wife. HIN, who chased FAY until he arrived at the security house, was happy to see CHING become somebody’s wife.

SHAN and FAY went to SIAO LIN and WU DANG but their heads of sects were kidnapped by a mysterious person. Someone had used FAY's name in killing people. RED FLOWER SOCIETY was blamed for all these crimes.

The poison in FAY’S body activated. LAN decided to see HONG with the pin that had the secret of CHONG’S treasure. In the morning, YAT found LAN disappeared and shadowed her to HONG’S home. FAY and other members arrived, saved LAN, and threatened HONG to hand out the antidote. Pathetically, there was no real antidote for FAY’S disease. LAN and YAT pretended to be happy in order not to let FAY know the truth. FAY, however, was depressed when he overheard their conversation.

Knowing his days were numbered, FAY disclosed that his love to CHING had not faded away so as to make LAN’S passion for him die. YAT gave FAY a sharp warning but LAN had already left with a broken heart. FAY could do nothing but chase after her. HIN knew what was on YAT’S mind and teased her that he would replace FAY’S position in her heart. YAT did not care. LAN was sedated and trapped by SHU in a bag.

HIN saved YAT in a wash and hid her in a barrel and brought her away. He was unfortunately beaten up and threw up blood. They however were safe from the danger at last. YAT questioned HIN why he save her even scarifying his life. HIN, finally bared his heart to YAT who nevertheless refused to accept him. LAN felt exhausted mentally and physically for FAY and refused to take medicine. FAY was broken hearted and begged FUNG for a chance. They finally buried the breach. Although HIN loved YAT who still missed FAY, he was confidant that YAT would be in his arms one day. On their way to the capital, FAY met BO and CHING. They then had a meal together and were happy that they each had found a suitable match. When they left, FOK sent royal guards to kidnap CHING’S twin babies. BO could not bear it and cut his own throat.

FOK’S guards took away the twins. CHING finished BO’S funeral and went to FOK’S home to get even with HONG. FOK persuaded CHING to stay for the sake of the twins' future but CHING could not decide.

On his way to the capital, LOK met WONG, one of the head of the BIG FOUR sects and knew the other three were poisoned. At the basement of the old house, LOK was hurt by ZHENG’S poisonous vapor. Unexpectedly, three leaders of the BIG THREE HEADS were pretended by CHOY, LUNG, and ZHENG. CHING, speaking incoherently in the midst of sickness, told them that LOK was in danger. YAT felt her behavior strange and thought she was able to die.
