Legend of the Lost Artifacts

Lainie Morales is a PhD in archaeology from a culturally diverse background with a passion for global history and culture. She gets a mysterious invitation from London, England, signed by Alexander Graham, asking her to help with ancient relics. Lainie loves archaeology and accepts the invitation, inviting her mentor Samuel Rivera to go with her.
At an old house in London, they meet Alexander Graham, who shows them ancient artefacts from South America. However, Alexander reveals his true colours and tries to use the artefacts to achieve his ambitions, threatening Lillian and Samuel with a gun. After finding out what Alexander was planning, Lillian and Samuel tried to escape in the dark. They finally managed to leave the manor house and go to Saint Malo in France.
In Saint Malo, they look for information about the markings on the artefact shard in an old bookshop. The shopkeeper helps them find a diary, but is then threatened by Lucas Morel. Lucas tells them to stop and they fight. Lillian and Samuel escape through the basement of the bookshop and follow the clue to an underground passage.
They meet many dangers in the underground passageways. First, they encounter mechanical traps and then attacks from metal blades and pale hands in the mist. At the moment of life and death, they rely on courage and wisdom, supporting each other, and find a secret door, temporarily escaping danger.
