Half of a month had passed as fast as a blink.
Shi Yan had been staying in the secret chamber for half of a month without caring about eating or sleeping. He had been concentrating on studying the ancient soul-scriptures of the Demonic Sound Clan.
After a half month, Shi Yan quietly walked out of the secret chamber without letting the people of Cao Zhi Lan's group know and the others. He got out of the ancient castle alone.
After he had just walked a few steps onto the streets of the Ancient City, the matriarch of the White Wings Clan, Yu Rou, suddenly appeared beside him, laughing out loud and then said, "Shi Yan, why did you suddenly want to leave?"
"I just wanted to take a walk and check on the Sound Beasts outside the city. By the way, I will practice some of the Heaven Flame Control techniques. Of course, You can, of course, follow me." Shi Yan said with a smile.
