The War Merchant's Alchemy Factory's Central Tower had four floors, and the first floor housed the Green Jade Gold Coffin, the second the Mermaid's Fairy Tale, and the third contained the second Blood Core.
Jia Sha opened the Teleportation Gate for the first time, sending the Green Jade Gold Coffin to a deserted island close to Mysterious Monster Island. The Mermaid's Fairy Tale, however, never had the chance to be sent out.
After the War Merchant was killed, the Mermaid's Fairy Tale fell into the hands of the knight youth and his companions.
After escaping aboard the Deep Sea Monster Fish, they arranged an alchemy array as per the Tower Spirit's hint and opened the Mermaid's Fairy Tale.
Upon opening the large clamshell, dozens of pearls appeared.
