Alan and the team take on a case involving a soul swap. In this case, two strangers suddenly discover overnight that their souls have swapped bodies. To solve this thorny problem, Alan and the team began to investigate deeply, trying to find the reason behind it.

During the investigation, Alan discovers a mysterious contract. The contract seems to be related to the soul exchange, but the origin of the contract is a mystery. Alan decides to lead the team in their quest for the origins of this mysterious contract, hoping to find a solution to the problem.

The team began searching for clues about the contract from libraries, occult research centers, and collectors of ancient books. They finally learned from a collector of ancient books that the contract was called the "Soul Contract", which was said to be an ancient, powerful contract. By signing this contract, people can exchange souls and even control the souls of others.

However, the power of this pact is too strong, and the cost is quite staggering. It is said that those who sign the contract will eventually be cursed, causing severe damage to their souls. After learning this information, Alan and the team were even more determined to save the affected souls.

Through their investigation, Alan and the team eventually found the two people who signed the contract - a young man who longed to be rich and an elderly man who was seriously ill. They chose to sign this mysterious contract for their own reasons, but now they are all deeply trapped in it, unable to extricate themselves.

In order to save them, Alan and the team set out to find a way to break the contract. After a series of twists and turns of exploration, they discover a mysterious power called the "Psychic Eye", which is said to release the soul from the contract. However, this power requires them to have a grueling conversation with their own souls in order to unlock the curse of the contract.

After a long wait and hard work, Eren and the team finally succeeded in lifting the curse of the contract, allowing the souls of the two victims to return to their original bodies. But the process was not easy, they all experienced a baptism of the heart, and deeply realized their inner desires and fears.

In the process, Alan and the team members also experienced a spiritual awakening. They begin to reflect on their values and re-examine their goals and motivations. This incident not only allowed them to successfully solve a tricky case, but also allowed them to grow spiritually.

The case is over, and Alan and his team have a deeper understanding of their knowledge of the occult realm. This experience made them realize that in the face of unknown forces, the courage to pursue the truth and save others is the most important thing.

However, as their investigation into the occult realm deepens, new challenges and threats emerge. In the following expeditions, Alan and his team will continue to face more unknown dangers, and they must always be vigilant and work hard to protect the peace of the human world.

After this experience, Alan and his team have developed a common belief that they will continue to pursue lost knowledge and uncover the secrets behind supernatural powers in order to better protect those innocent. They firmly believe that it is only through continuous exploration and learning that all the mysteries of this world can finally be revealed. And all this is just the beginning of their adventure story.
