Chapter 478: Chapter 360 Practicing Skills, Mutant Curse!_1

The next day, after sending Yao Zhixue off on the high-speed train back to Chang'an City, Zheng Cheng and Cai Ji embarked on the road to level up.

Cai Ji was leveling up, whereas Zheng Cheng himself was preparing to find suitable wild monsters to practice and improve his skill proficiency.

A few days later, their figures appeared in an Underground Labyrinth.

Located in the northern suburbs of Beijing, the Underground Labyrinth was home to a large number of wild creatures.

The Underground Labyrinth had nine levels, each with numerous Territory's Hearts, passively summoning corresponding plane Monsters.

It was also one of the hottest spots for Professionists in the Beijing region to level up.

Because of the orders from the Elders Council and the Professional Guild, some powerful Professionists would not actively destroy the Territory's Hearts.

They maintained it to ensure there were always plenty of wild monsters for lower-level Professionists to level up with.
