Russell didn't immediately return after completing his mission, and the reason was simple.
It was because he had too many people to take with him.
Lin Qin no longer wanted to return to Sun Island—even though Russell had asked if she wanted to take revenge on her mentor, who had used her.
But after careful consideration, she decided to let it go.
It wasn't that she chose to forgive, but she believed that this matter shouldn't be handled by an outsider.
It would either be shelved or wait until Lin Qin herself had grown enough to come back and settle it personally.
She decided to follow Russell back to Happiness Island—officially to respond to the talent introduction policy and join the Special Execution Department; but in reality, she was joining Babel, which was currently active on Happiness Island.
Including Bubble-30, the synthetic humans also no longer wished to stay on God Communication Island.
