As Shin opened the mysterious letter, the system immediately informed him of the contents.
*Ding*
System: You have received the old letter of the Second Holy Maiden of the Temple of the Moon, which she had sent for Fifth Envoy Altus.
System: The Letter is filled with coded words and runes that you can't decipher. It is the unique language of the Sun and the Moon.
System: Head to the Church of the Sun and Moon and look for a Cardinal to decipher the message.
*Ding*
System: A surprise may be waiting for you.

Seeing the system messages, Shin could not help but smile bitterly for a moment. He first thought that he would directly gain the clue about the [Ring of the Abyssal Moon], but he was wrong.
It seemed like he needed to look for Cardinal Ronald to help him on this one. Fortunately, his relationship with this old cardinal was quite close, so it would not be hard to ask for help for something like this.
