Alan and Sophie have made a name for themselves after solving a series of tricky cases. The battle between justice and truth fills their lives with tension and excitement. However, on these seemingly peaceful days, a new conspiracy is quietly brewing.

One night, Alan receives a mysterious phone call. The voice on the phone is slightly magnetic and apparently has undergone a voice-changing treatment. They told Alan that they had important information about the Shadow Order's ongoing illegal activities, and hoped to work with the Night Investigation Bureau to eradicate this evil force once and for all. However, the veracity of this information makes Alan and Sophie suspicious.

In order to verify the authenticity of the information, Alan and Sophie decide to take matters into their own hands. They arrive at a remote abandoned factory, which the mysterious man has alleged to be the secret base of the Shadow Order. However, when they infiltrated the factory, they found that it was deserted and everything seemed strangely quiet. Just as they were about to leave, there was a sudden loud explosion. It turned out that it was all a well-laid trap.

The bomb exploded inside the factory, and the fire spread rapidly. Alan and Sophie are in a life-or-death situation. They clung to each other, trying their best to escape the fire. During the escape, Alan noticed some unusual details: first, the location of the explosion happened to be the only way for them to enter the factory, and it seemed that someone had predicted their course of movement in advance; Secondly, the timing of the explosion was also very accurate, just the moment they fell into the trap, suggesting that the people behind it had a deep understanding of their actions.

What disturbed Allen the most was that the nature of the explosives felt familiar to him. After careful identification, he found that the explosives used in the bomb were similar to the components of the biological and chemical weapons they had previously seized, indicating that the person who made the bomb was not only proficient in the manufacture of explosives, but also familiar with the principles of biological and chemical weapons. This made Alan realize that the trap might be related to a high-ranking member of the Shadow Order, and their actions had already alerted the other party.

After many hardships, Alan and Sophie finally escaped from the fire. However, the trap worries them deeply. The forces of the Shadow Order have become so rampant that they even dare to retaliate against them. Alan and Sophie understand that in order to protect themselves and their families, they must act quickly to eradicate the Shadow Order once and for all.

Back at the Night Investigative Bureau, Alan and Sophie provide an in-depth analysis of the incident. They believe that this trap is clearly in retaliation for their previous actions against the Shadow Order. Moreover, the cunning and viciousness of the enemy's operation made them intrigued by the high-ranking members of the Shadow Order. They decided to dig deeper and find out who was behind it.

In order to investigate who is behind the trap, Alan and Sophie begin to collect relevant clues. Through the analysis of the bomb explosives, Allen found that the explosives were similar in composition to the biological and chemical weapons they had previously seized, which means that the mastermind behind the trap was likely to be one of the core members of the Shadow Order. In order to obtain more information, Alan and Sophie begin an investigation into the high-ranking members of the Shadow Order.

After some hard work, Alan and Sophie finally get a key clue: one of the high-ranking members of the Shadow Order is a person named "Ghost", who specializes in making bombs and biological weapons. He used similar explosives in a terrorist attack in a certain part of Europe to cause a large number of casualties. This convinces Alan and Sophie that the ghost is behind the trap.

However, in the process of finding the ghost, Alan and Sophie encounter an unprecedented dilemma. The ghosts are as elusive as ghosts, and their investigations have repeatedly stalled. Just when they are at their wit's end, an unexpected discovery gives them renewed hope: the ghost once had a partner, and that partner is now behind bars. Alan and Sophie decide that they will start with this partner and find clues to the ghost.

However, Alan and Sophie unexpectedly expect that when they thought they had touched on the ghost's true identity, they found that it was just the beginning of an even bigger trap. Among the high-ranking members of the Shadow Order, there is an even more cunning and dangerous enemy. And this enemy is secretly planning a conspiracy that can shake the world.

Alan and Sophie bring the ghost's partner back to the Night Investigation Bureau for interrogation. After a fierce exchange, the partners finally relented and revealed some information about the ghost. He tells Alan and Sophie that the ghost, whose original name was Markov, is a genius chemist who was once internationally famous. However, in an experimental accident, his family was killed, giving him a strong hatred for the world. Since then, Markov has joined the Shadow Order and become a "ghost".

The partners also tell Alan and Sophie that the Ghost is planning a terrorist attack on an unprecedented scale in an attempt to create a new type of biological weapon that will throw the world into chaos. In order to stop this terrorist attack, Alan and Sophie must find the ghost as soon as possible and stop his crazy plans.

Alan and Sophie discover a secret hideout in the city through clues provided by their partners. The clues mention that the ghost often haunts an abandoned factory, and that there is a basement inside the factory, which is said to be a temporary storage place for the Shadow Order. In addition, the clues mention some of the Ghost's characteristics, including his distinctive tattoos, black hair, and the fact that he always wears a pair of sunglasses, even at night.

Based on these clues, Alan and Sophie begin to closely monitor the surroundings of the abandoned factory, trying to catch traces of ghosts. After several days of squatting, they finally found a suspicious man who matched the description of the clue in one night. He was trying to sneak into the factory, looking nervous and looking around from time to time.

After confirming that the target was correct, Alan and Sophie immediately launched an unexpected raid. They took advantage of the environment and quickly subdued the ghost and tied it up. However, just when they thought they had succeeded, the ghost smiled slyly and used his life to activate the detonating device of a new type of biological weapon hidden on his body, in an attempt to plunge the entire city into ruin.

In a life-or-death situation, Alan and Sophie tried their best to disarm the detonating device of the new biological and chemical weapons. However, the ghost's death did not leave them feeling relieved. They are well aware that in the shadow of the Shadow Order, there are still countless dangers. In order to protect the peace and tranquility of the world, Eren and Sophie must continue to fight and thwart the evil plans of the Shadow Order.

At this time, the high-ranking members of the Shadow Order have begun to hatch a new conspiracy after the ghost's death. A mysterious figure named "Behind the Scenes" becomes their new leader, who is plotting an even more cunning and dangerous operation. How will Alan and Sophie respond to this new enemy? Will they be able to emerge victorious in this contest between good and evil? The story will continue in the next chapter
