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. A royal decree posted declared the execution of LOK and any rescue attempted would probably in vain but the members of the Society would not regret to do so.
