After having a good and informative chat with the Sun Demi-God, Ling Chen didn't quickly leave the city but chose to stay for a few days in the Fire Phoenix Palace.
Though he was able to gather a lot of useful information from the Sun Demi-God, there're still many key pieces of information that he wasn't able to acquire as even the Sun Demi-God herself didn't know them.
Such as the location of the Great Luo Martial God's Tomb or the whereabouts of the Great Luo Martial God?
According to the Sun Demi-God, there's only one person throughout the whole world who knew this information and that was an old man known as Old Yan.
Not only Old Yan was the oldest Demi-God throughout the whole Great Luo World, but he was also the only survivor of the previous generation of Demi-Gods which had entered the Great Luo Martial God's Tomb 3000 years ago.
