Allen's team receives a new case involving a mysterious cult. The group is said to be performing some strange rituals that seem to be related to an evil force. In order to uncover the truth of the matter, Alan and his team begin an investigation into this cult.

During the investigation, Allen's team discovers that the members of this cult possess some kind of mysterious supernatural power. At the same time, they also discover that another mysterious force is fighting the cult in an attempt to stop their evil plans. Alan and his team decide to investigate these two mysterious forces in depth and find out the truth behind them.

In the ensuing investigation, Allen's team gathered a lot of information about the cult. They discover that this organization has been around for a long time, and that it has fought many fierce battles with other mysterious organizations over the centuries. The cult is trying to use their power to conquer the world, while another mysterious force has been trying to thwart their ambitions.

It became increasingly clear to Allen and his team that what they were facing was not a simple case, but a global confrontation of power. They must reveal the truth behind it and stop the spread of evil forces.

During a search operation, Allen's team managed to infiltrate the cult's stronghold. There, they discover an ancient magic book that records some powerful evil spells. This book seems to be the source of the cult's strength. Alan realizes that they must find a way to stop the cult as soon as possible, or the consequences will be dire. At the same time, Eren began to think to himself that maybe they could use the power of this magic book and join forces with another mysterious force to fight the cult together.

To ask for help, Alan contacts Serra, a psychic who had previously worked with them. She had heard of the magic book and warned Eren not to try to use these spells lightly, as those powers could plunge people into a dark abyss from which they could not extricate themselves. However, she agrees to help Allen's team get in touch with another mysterious force and work together to develop a plan against the cult.

After some hard work, Allen's team finally found contact with another mysterious force. It is an ancient secret organization that was founded centuries ago to fight against the forces of evil. They provide invaluable support and guidance to Alan's team on how to harness the power of this magic book while avoiding being corrupted by it.

With the help of the secret organization, Alan and his team begin a fierce battle against the cult. The two sides have clashed many times on different occasions, and each battle is very thrilling. However, as time went on, Allen found that their power was gradually increasing, while the power of the cult seemed to be waning.

Eventually, in a decisive battle, Allen's team managed to defeat the leader of the cult, free the innocent people imprisoned, and stop the cult's evil plans. They handed over the magic books to the secret order, hoping that they would keep them safe and ensure that those powers would not be misused again.

After this series of battles and challenges, Alan and his team members have become more mature and stable. They understand that supernatural forces can bring great power, but they can also lead to devastating disasters. In future work, they will be more careful in dealing with paranormal phenomena
