"The next duel will be...stone boat races!"

"Ha! That? It sounds as easy as stealing a human's life. What's more, let my partner take charge of winning this time."

Those were the words issued by Seth so that you would end up in the middle of the banks of the Nile River, building a stone boat (with clear help from Seth who had used his sand to knock down and break rocks that were used to mold a boat). . The only thing you had to do was hide that he was helping you (or well, cheating if the gods realized).

Horus, on the other hand, seemed to take his time building his ship by hitting some stones with the help of his pickaxe. Only he could know his plan.
