Du You ultimately could not compare with those powerful factions. Lacking sufficient resources, he could not afford to give up the development of any world casually. This time, he had to participate in the face of the threat.
Of course, while it was a threat, it was also an opportunity. The most troublesome part was how not to cross the Alliance's bottom line.

This time, it was possible that more seventh-tier experts would be involved, making him less conspicuous in comparison.
After making some brief preparations, Du You took the two sisters and Ke Jisi back to the Star Ring World.
