The old man who appeared beside Arlo Drake was none other than the first Elder Silver Flame of the Black Tortoise, 'Maximus Lee', who was also Arlo's master.
At first, the reason he was willing to take Arlo as his apprentice was because Arlo promised to let his cousin, a Martial Dao genius endowed with a 'blue spiritual root', join his ranks as well.
In essence, it was out of respect for Arlo's cousin that he accepted Arlo as his apprentice.
Today, after receiving the report from Elder Copper Flame notifying of Arlo's cousin's arrival at the Fire Worship Sect, at the Black Tortoise, Maximus was very pleased, eagerly waiting for Arlo's cousin to visit him after catching up with Arlo to perform the 'apprentice ceremony'.
Who would have thought, instead of the expected arrival of a person, he would receive astonishing news.
Arlo's cousin 'Long Drake' disregarded the sect's rules and attacked Wyatt Barnes at the Black Tortoise disciple's residence, intending to kill Wyatt.
