The pocket universe formed by the Sky-Stealing Sun-Swapping Art wasn't as complicated as the Endless Sea of Stars. It lacked a portion of the details, but the general outline was the same.
Zhou Wen explored the Endless Sea of Stars as he grinded. Through his observations of the Endless Sea of Stars, he gained insight into the profundity of the Sky-Stealing Sun-Swapping Art.
Since Zhou Wen wanted to search for Astral Combat Beasts in the Endless Sea of Stars, it wasn't considered a waste of time.
He had been too busy recently, so Zhou Wen didn't have the time to grind the Lunar Mansion skills and Astral Combat Beasts. The twenty-eight Lunar Mansion Skills were still lacking three key skills, so the Star Stealer's Essence Energy Skill Crystal hadn't dropped.
Now was the perfect opportunity to explore the Endless Sea of Stars and find Astral Combat Beasts.
