"...My friend, humanity welcomes your joining!"
The human warriors initially wanted to reject Su Yu's joining, after all, Su Yu now looked completely monstrous.
But Su Yu secretly used the Book of Narrative to rewrite part of their setting, so they naturally agreed to let Su Yu join.
The result of rewriting the setting through the Book of Narrative was that their thoughts came from the heart, not brainwashing by any Spiritual Power.
After all, the thinking of life is inherently elusive, and these human warriors, with rich experience in dealing with aliens, had seen many "Alien Traitors" and even fought alongside such beings.
Their initial desire to reject Su Yu was primarily because Su Yu's strength was too formidable, which made them a bit apprehensive.
But seeing Su Yu's "sincere" tone and having previously killed numerous Brain Demons with significant contributions, agreeing to his joining seemed reasonable.
Su Yu writing like this wouldn't cause a logical collapse.
