It wasn't that long ago when Chu Mu first stepped foot onto World City's land, entering the Eighth-Level Mysterious Realm. He faced a Commander-level Soul Pet with a ninth rank intermediate stage.
At that time, Chu Mu had done his utmost to kill the ninth-rank intermediate Horror Wolf. But now, without stepping into the first realm, he had to face a tenth-rank Commander. It meant that he hadn't even touched the edge of the second-tier first realm back then.
If he had continued to develop in that manner, Chu Mu believed that he would still be a nameless foot soldier in World City. Even if he earned some glory in the third-tier, it wouldn't be enough to satisfy Chu Mu.
Therefore, Chu Mu felt that his decision to challenge higher ranks was correct. Without experiencing dangers and confronting those difficult-to-face creatures, how could he unlock his full potential and improve his strength in the shortest time possible?
