I'm here to return your storage ring

Chang Bo is an orphan who was raised by a retired low-level adventurer after finding that he was born with high-quality ether.

Despite being poor, his early life went well but when he was twelve, the old man died of a heart attack, leaving behind heavy debts that cost him the house and the boy was on the streets once again.

Thankfully, by then, he's already broken through the 2-circle realm and could fend off himself. Although his cultivation realm is low, he was still a swordsman. So, the Swordmasters guild took him in. 

In the past three years, he changed different teams but in the end, he only became an errand boy.

Like other citizens, he too attended the public trial and had seen Lu Zhen and the other two.

When he realized the situation, Chang Bo saw an opportunity and immediately volunteered to sell out Mo Jiang despite the fact that he was once teammates with the latter.
