The other reason why Li Yao needed to go to Serpent Mountain Village was to uncover the secrets of his Cosmos Ring.
On his way back to the Grand Desolate War Institution, he had tried cracking the encryptions in the Cosmos Ring with his mini crystal processor.
But it didn't take long before he discovered that there was a double-encryption inside the Cosmos Ring. It seemed that two zones, one larger and the other smaller, had been sealed in it at the same time.
Li Yao inferred that the larger zone must be the snake demon's storage space, whereas the smaller zone was probably the storage space of one of the ring's former masters.
The ring's previous owner had set up a strong encryption inside the Cosmos Ring that the snake demon failed to unseal. Therefore, the demon simply added another encryption over the old one.
