City Lord Noel was so excited that tears started rolling down on his cheeks.
"City Lord, do you know the origin of this key?"
Li Yi asked straightforwardly.
City Lord Noel heard Li Yi's question and noticed that he had lost his composure. He looked around and immediately cleared his throat and calmed down.
"Well, Heavy Armored Dragon Knight, if I'm not mistaken, this key should be the Key of Remembrance that Emperor City lost 300 years ago! It should be the Key of Remembrance that Emperor City lost 300 years ago!"
Noel's eyes burned with passion as he spoke.
"Key of Remembrance?" Li Yi asked yet again to reconfirm what he had just heard.
"Yes, please wait right here."
Noel turned around and started to quickly search for something. Half a minute later, he returned to the three of them with a dusty book that looked frail.
