WARNING: This article have spoilers for the first three episodes of The Curse of Oak Island season 8. Read at your own risk.

The Curse of Oak Island season 8 episode 4 is coming thing week on History Channel. The previous episodes saw the team making significant discoveries, including the old gold coin (possibly belongs to the Chinese) and traces of industrial activities.

In The Curse of Oak Island season 8 episode 4, viewers will see brothers Rick and Marty Lagina and their team digging further deep down in order to locate the Money Pit. Despite the challenges brought by the COVID-19 pandemic, the fellowship won't stop until they unearth the speculated treasure.

In episode 3, the team discovered an ox foot located near the Money Pitt's potential area. Blacksmith Carmel Leggae noted that the traces were possibly British, which leads to another speculation. It was suspected that the oxen were used to carry out heavy materials into the speculated treasure.

The Curse of Oak Island season 8 episode 4 will likely see the team further investigating what does their latest discovery means in their journey. The oxen foot may have suggested that strong industrial activities occurred in the mysterious island hundreds or thousands of years ago.

The team will have to conduct more exploration and investigation to find out what other secrets lie on the island. Gray Drayton and Jack Begley believed that their latest discovery could lead them to the track between the paved wharf and LOT 15 and the mysterious anomaly in the swamp.

The oxen trail might be the major focus in the upcoming The Curse of Oak Island season 8 episode 4. This recent finding could provide some answers surrounding the island. Also, some believed that the trail could direct the team in the possible location of the Money Pit.

And while they've found evidence of French and Spanish activities on the island, Drayton's discovery of the old gold coin gave them a clue that there were presence of Chinese people in the past. They strongly believed that the item belonged to the latter.

There's a debate on whether the old coin was from Chinese laborers who worked for the British or it was the Chinese who buried the Money Pit on the island. The fellowship will continue to look for answers, and everything seems easy now that they proceeded in the project "Big Dig."

The Curse of Oak Island season 8 episode 4 airs on Tuesday, Dec. 1, on History Channel.
