At the moment when the ghost triggers the detonating device of a new bioweapon, Alan and Sophie act quickly to try to stop the catastrophe. Luckily, before the ghost was arrested, they had researched an antidote in advance, perhaps to neutralize the poison produced by the biological weapon. However, making the antidote requires some rare raw materials, which are scattered all over the city.

Alan and Sophie didn't have time to hesitate and immediately split up to find the raw materials needed for the antidote. Alan is tasked with finding a mysterious plant called the Blue Moon Orchid, which is said to grow in a barren valley north of the city. Sophie, on the other hand, travels to a laboratory in the south of the city, where it is said to contain a rare compound, fluorbutartrate, which is a key ingredient in making an antidote.

After a strenuous trek, Alan finally found the Blue Moon Orchid in the valley. It is a beautiful and mysterious plant with pale blue flowers and a faint fragrance. At the same time, Sophie also found fluorparate in the laboratory. Despite the difficulties they encountered in finding the ingredients, they always believed that if they worked hard, they would succeed.

When Alan and Sophie find the ingredients, they immediately return to the Dark Night Investigation Bureau and begin to develop an antidote. Time is of the essence, and they must craft enough antidote before chemical and biological weapons cause a large-scale catastrophe. After some intense experimentation, Alan and Sophie finally succeeded in developing an antidote. They immediately reported the situation to the city's health department and the government and provided a prescription for the antidote.

The health department and the government acted quickly to quickly distribute the antidote to medical facilities throughout the city and began treating citizens affected by chemical and biological weapons. Fortunately, thanks to the timely detection and response of Alan and Sophie, the impact of the disaster did not widen, and many citizens' lives were saved.

However, simply stopping the outbreak of chemical and biological weapons wasn't enough to give Alan and Sophie a sigh of relief. They understand that as long as the high-ranking members of the Shadow Order remain at large, the world will never be at peace. In order to completely destroy the Shadow Order, they decide to investigate deeply and find out who is behind it.

Alan and Sophie uncover an important clue through their investigation of the ghost. It turns out that in the ghost's hideout, they found a worn-out notebook. The notebook contains confidential conversations between the ghost and high-ranking members of the Shadow Order, as well as a crumpled map.

The map shows an abandoned factory on the outskirts of the city, with a corner circled in red and a "secret base" in the corner. The map also features several pick-up points and entrances, as well as a mysterious underground passage that leads to the Shadow Order's secret base. It seems to leak key information, but in reality, it is exactly the trap deliberately laid by the Shadow Order, waiting for Alan and Sophie to take the bait.

Alan and Sophie decide to take the plunge and infiltrate this secret base to find out. During the infiltration, they discover that a huge secret laboratory is hidden beneath the abandoned factory, where various forbidden biochemical experiments are conducted. It was through this important clue that Alan and Sophie found the secret base of the Shadow Order.

After a painstaking trek and careful planning, Alan and Sophie managed to infiltrate the secret base of the Shadow Order. The interior of the base is intricate and fraught with danger. They discover a shocking secret in a laboratory: the Shadow Order is trying to develop an even more lethal biological weapon with the aim of creating mass panic and chaos on a global scale.

Alan and Sophie immediately realized that they had to act quickly to stop the Shadow Order's plot. However, just as they prepare to destroy the lab, a high-ranking member of the Shadow Order suddenly appears and captures them both. It turns out that this secret base is a trap laid for them by the Shadow Order. And the map left by the ghost is exactly the information they deliberately leaked.

Alan and Sophie are in trouble. They were locked up in a cell, and the high-ranking members of the Shadow Order mockingly told them that a grand sabotage plan would soon unfold, and that they would witness it all with their own eyes. Alan and Sophie are anxious, but they can't do anything about it. They know that in order to save the world, they must escape this trap as soon as possible and expose the crimes of the Shadow Order.

As Alan and Sophie venture deep into the secret base of the Shadow Order, their partners learn that they are in trouble and decide to take immediate action to launch an intense rescue operation.

The partners first found the location of the abandoned factory from the map, carefully studying the warning points and entrances on the map. They realize that in order to enter the factory and rescue Eren and Sophie, they must first crack the Shadows' tight security system. So, they divided into several groups, each responsible for a part of the task.

The first team is tasked with gathering intelligence and investigating how many people the Shadow Order has placed around the factory and what surveillance equipment has been installed. The second group began to study how to bypass these security facilities, and they consulted an expert on how to crack electronic locks and surveillance systems. The third group focuses on planning entry and exit routes, providing the best options for infiltration and evacuation.

The rest of the Night Investigation Bureau, through a series of covert clues and secret communications, find the location where Alan and Sophie were imprisoned. With their excellent tactics and intelligence, they managed to bypass the Shadow Order's defenses and infiltrate the secret base without a word.

Meanwhile, Alan and Sophie are struggling in their cells, trying to find an escape. Eventually, Alan discovers a hole in the structure of a cell, and they break down the door while the members of the Shadow Order are not looking. At this time, the rescue team of the Dark Night Investigation Bureau has also penetrated into the depths of the base and joined up with Alan and Sophie.

After a fierce battle, the members of the Night Investigation Bureau managed to repel the forces of the Shadow Order and found the lethal biological weapons research and development room. At the last minute, Alan and Sophie managed to stop the creation of chemical and biological weapons and destroy the lab. The Shadow Order's conspiracy was shattered, and their high-ranking members were captured one by one.

However, the joy of victory did not make the members of the Dark Night Investigation Bureau let their guard down. They knew that the battle had been won, but the Shadow Order had not died out entirely. In this world, there are always some people who try to use evil means to achieve their goals. The mission of the Night Investigation Bureau is to stop these evil forces and protect the peace of the world.

This shocking reversal left a profound lesson for Alan and Sophie, and it also strengthened their beliefs. They know that as long as they work together and move forward, they will be able to overcome all difficulties and drive the evil forces from the earth.

At this moment, the members of the Dark Night Investigation Bureau are ready to take on a new challenge. In the journey ahead, they will continue to wage fierce battles against the forces of evil and defend justice. And this earth-shattering reversal will always be remembered in their hearts and inspire them to work hard for a better future.
