Season 1 (2016)
In a prologue, the cast is introduced to the settings and suspects of a murder case for the new episode. The cast then chooses their role in the episode, as a particular suspect or the detective. Other than the detective, each person is given detailed information about the suspect they are portraying including their personalities, alibi, relationship to the victim and other suspects, history, criminal motive, etc. Every suspect can conceal information until explicitly questioned by other suspects or the detective, but only the criminal can lie. * Alibi: Each player introduces themselves as the suspect they are portraying, gives some background information about their relationship with the victim, and describes their whereabouts before, during and after the crime. *On-Site Investigation: The players are separated into two teams, and given ten minutes to investigate the crime scene for clues. Each player is given a camera, and is allowed to take a maximum of ten pictures. * Briefing: All players present the evidence they have collected, and are allowed to ask other players questions concerning evidence. Each player voices out who they currently think is the criminal after their briefing. * First Criminal Vote: The detective is allowed to make a vote on who they suspect after hearing each player's briefing. The vote is made publicly to all of the players. * Additional On-Site Investigation: All the players gather at the crime scene for additional investigation and discussion. This segment is run at the same time as the 1-on-1 Interrogation. * 1-on-1 Interrogation: The detective who is always innocent can summon the other players into the interrogation room for further questionings. * Final Criminal Vote: After all of the players have been interrogated, the game proceeds to the final vote. All players makes their final statement and debriefing of the case would be conducted by the Detective. 5 minutes of individual investigations would be permitted before each player secretly votes for who they think is the final criminal. The player who receives the most votes is arrested and locked in a makeshift prison. If the person is indeed the criminal, the detective receives two gold bars, and the innocent players receive one each. If the arrested person is not the criminal, the true culprit gets all the gold bars.Season 2 (2017)
In the second season, minor changes were made to the format of the show. The gold bars are given to the cast members beforehand. If they vote correctly, they can keep the gold bar. If not, they will have to return it. When the cast members are choosing their roles, they do not know who is the detective until they open their character cards. The detective is no longer allowed to make his first vote publicly, so that the cast will not be influenced. At the end of the game, if the right suspect is voted as the criminal, only those who voted correctly get to keep their gold bars. Detectives voting correctly both times get two gold bars. Suspects successfully hiding their identity get all six gold bars. In episode 12, all six cast members are suspects.Season 3 (2017)
In the third season, all the scenes have become realistic, in which the cast members experience the whole crime setting themselves. Props and the background of the cases are all original and solid, such as the hotel in episode one. There are one to two victims for each case, making the cases far more complex than the previous two seasons.Season 4 (2018)
Season 4 began in October 2018, and continued to use actual sets for some of the episodes. The detective's assistant role, which appeared briefly in Season 2, was brought back for this season and played by various university students.Season 5 (2019)
Season 5 began in November 2019, and in the first episode an actual location (cruise ship) was used as a set instead of a production set which was utilized in previous seasons. The detective's assistant role has also returned for this season, and the format of the previous seasons appear to have been unchanged in this season.Season 6 (2020)
Season 6 began in December 2020. This season has a new addition of the double detective mode. Double detective mode means there are now 7 players in total and the detectives get to cast two votes each. Other than that, the format is the same as the previous seasons.Season 7 (2022)
Season 7 began in January 2022. This season is the first season where Benny Sa is absent from the cast. In replacement, Wowkie Da and Zhang Ruoyun joined the regular cast, while Wang Ou, Vision Wei, and Yang Rong became recurring members. While this season continued the double detective mode, the detective's assistant only gets to vote once during the second voting round. Another change was the change from gold bars to detective badges for scoring. Similar to the previous seasons, if the criminal is caught, the detective gets badges equal to the number of times they voted correctly, and the assistant and other players get a badge if they voted correctly. If the criminal wins, they win 6 detective badges. Players also vote for the MVP at the end of the episode, and each episode's MVP earns one badge. The winners of episode 0, the prior gathering, also earn one badge each. At the end of the season, among all the cast members (except for fixed member He Jiong), the four cast members with the most badges earn the title of "Stellar Detective".Season 8 (2023)

Disappearance of Sa
(Spoilers for Season 7)
To deal with Sa Beining not being able to join the filming for Season 7 due to work issues, a special over-arching story was told in Season 7. In Episode 0, it's revealed that Detective Sa, leader of the Famous Detective Agency on Mango Planet, had gone missing while investigating a special case. Detective He was made deputy leader and given the Season long task of tracking down Sa. In Episode 1, Sa is referenced when a doll with his likeness is found and stated to be irreparably broken. In Episode 2, Sa is again referenced when the cast finds his character's building access card defaced. In Episode 3, the cast finds mention of Emperor Sa mysteriously disappearing in the historical records. In Episode 4, the cast briefly discovers an SOS message from Sa hidden in a radio broadcast. Detetive He then tells the cast that he suspects Sa is in danger. In Episode 6, Sa's NZND character is revealed to be in a coma. In Episode 10, it is revealed that planet M is undergoing an ice age. A mysterious group called "Watcher" has come to the conclusion that because places warm up when visitors from planet Mango arrive to help solve murders, to save the planet more murders must occur. Detective Sa under an old alias of 'Animal Sa' had visited the bunker to investigate the situation. Psychologist Bai from, who worked for "Watcher", also visited the bunker and ended up giving the murderer the plan for the murder for that episode. At the end of Episode 10, Detective He receives a fax from Detective Sa saying the truth will be revealed in Ding Niu City. In Episode 11, the entire episode revolves around the resolution of "Watcher" and Detective Sa's conflict. Five of the seven players are revealed to be murderers from episodes in previous seasons. Sa had kept in touch with each of them to try and help them reform and become better people. When Detective Sa had discovered the crisis on Planet M and the existence of Watcher, he went to try and investigate. Eventually Sa discovers that "Watcher" is an AI developed by Mathematician He to save the planet with his observation that they need to bring more people from Planet Mango to Planet M to warm it up, even if it means more murders. Sa realizes that Mathematician He was wrong in his theory because when his NZND character awoke from the coma, he discovered that the elderly home was warm and free from the effects of the ice age, despite the Planet Mango beings having left long ago. Sa realizes that it was not the arrival of planet Mango beings to solve the murders that brought warmth but the love and friendship they displayed whilst solving the murders, the same love and friendship that the NZND members in the elderly home continued to exhibit, thus warming their region. It is finally revealed that Mayor Zhen, Mathematician He's partner, accidentally enabled the Watcher AI to have full autonomy and kill as required, resulting in his own death as well. Watcher then planned to murder Sa to silence him.Season 8 (2023)
Overarching storyline for season 8 The season starts with episodes 1&2 taking place in sunset mansion where the players unravel the mystery of the caretaker of the mansion who cannot physically leave the mansion but can teleport his/her consciousness through time into another person's body. The theme of changing the past and alternative timelines is also brought up. At the end of Episode 2, Ou becomes the caretaker, having killed the former caretaker Jia. In episodes 5 and 7, the theme of consciousness of one person going into the body of another is brought up again. In episodes 5, the TianDing group is introduced as the preeminent technological group on the planet and that the black detective agency was investigating them due to the group being suspected of using mind control chips to carry out crimes. Ironically the murders in this episode also occur due to the chip. A mysterious figure Sa is also mentioned. In episode 11, we return to the outside of sunset mansion where the TianDing Group president has been murdered while trying to uncover the caretaker's secret. In episode 12, all threads are brought together. It is revealed that TianDing used the mind control chips to harness all human brain power together into a super AI, TianTian. TianTian, in trying to create a utopia, uses the chips to mind control some people to commit specific murders so that her best calculated outcomes are achieved. Sa is revealed to be the consciousness of Sa from the Season 7 finale that somehow ended up in this dimension. Sa, in trying to find a way back home, stumbles upon TianTian and her crimes. Sa tries to intervene in some of TianTian's murders but doesn't always succeed, resulting in a split timeline. In one timeline, TianTian's utopia is created and in the other, TianTian is shut down. Sa and TianTian meet to discuss the timelines and Sa reasons with TianTian that a utopia with no freewill is not actually a utopia and TianTian reasons that as long as humanity is ultimate safe and happy, freewill is a small price to pay since humans do not know best and are self-destructive. Sa eventually sacrifices his existence in this dimension to enter a bet with TianTian for the future of humanity with the episode 12 final vote deciding the outcome of the bet.Season 9 (2024)
Storyline for season 9 In episode 11, players gather in Wai Amusement Park where Detective Zhang is invited by an unknown person to investigate the truth of the Rat King and a mysterious character the players call "D". It is revealed that "D" is controlling the Amusement Park, motivating the players to play the Hunting Game, tracking the players' movements and live-streaming the Game. At the end of the episode, it is revealed that "D" also invited Detective Zhang to the Amusement Park. In episode 12, the threads from the previous episode come together. The citizens of the XiYou City are all fascinated by the Rat King, which has gone out of control and become a destructive force. Recently, there are four unfinished cases (Student Sun, Internet Celebrity Su, Boss Gou, Principal Xu) and one case involving Chairman Dong that Detective Zhang is investigating. Detective Zhang called the players connected to the unfinished cases to find the truth. It is revealed that the Rat King himself was the mastermind behind the four cases. Fans of the Rat King vote on his victims; the Rat King set up everything so the suspects can kill the victim. Throughout the investigation, it is revealed that the Rat King is the younger brother of MCN Boss Rong called Rong Xiaotang. Rong Xiatong planned the cases. First, to avenge his classmate, Xiao Ye. Xiao Ye was bullied Sun, Su, and Ou. Principal Xu also sided with Ou. This resulted to Xiao Ye killing herself. Second, Boss Guo copyrighted Xiaotang's comics. Xiaotang originally drew the comic, creating a harmless red-nosed rat. But Boss Guo registered the comic to use as pranks. Therefore, Xiaotang killed Xu and Guo, and poisoned Sun, Su, and Ou. Ou survived, and Xiaotang made a deal for Ou to help him with the murders, or else she would die. Ou killed Rong Xiaotang to escape the deal. Both He and Liu admire the Rat King. They believe the Rat King brought light to XiYou City. Chairman Dong is revealed to be "D", a copycat of the Rat King, and is using the image of the Rat King to play pranks. "D" is voted to be the Rat King's next victim, but the Rat King never responded. He didn't want the Rat King's reputation to be tarnished, so he decided to kill "D" in tribute. Under the name of the "Hunting Game" mentioned in episode 11, He arranged to meet "D" in the abandoned building that episode 12 takes place at. Many admirers of the Rat King gather at the abandoned building and He planned to find a partner among the Rat King's admirers. Liu was angry at "D" for using the Rat King's name to kill others and tarnish the Rat King's reputation. Liu had expressed his willingness to help the Rat King in the market. Liu met He at the market and decided to cooperate with He to kill "D". Liu contacted "D" under the name "E" with the pretense to provide a hunting game location. Liu met "D" at the market and invited him to the abandoned building for a discussion. Liu then stunned "D" and secured him with a string on the building's second floor scaffolding. He waited outside the abandoned building and saw that Liu had already secured "D" with a string. He tightened the string on the first floor and hid nearby to create an alibi. He returned and cut the string, making "D" fall from the platform. He then cleaned up the scene and left. When Zhang called He and Liu to investigate all cases related to the Rat King, both agreed because they are interested in the Rat King's true identity. Based on the investigation, He and Liu found the Rat King's true identity to be Rong Xiaotang. They met Xiaotang and he gave the Rat King's ID to both of them to decide its future. He and Liu then used the ID to announce the Rat King's return.Controversies
