If it wasn't for Lai Mingjie's trust in his newfound power, he wouldn't have tried to force his way through the golden barrier. The power of the spirit dome resonated with that golden light in his demon core. He also felt immune to the spirit-corroding fumes which made him solidify his resolve to seek out Zhenye. He didn't know what Bingxing planned for this poor dude, but he knew Bingxing.
Once he determined someone as his enemy, he would crush this person... regardless of who they once were.
Zhenye wasn't exactly friendly among the sentinels. He was an ass to most of them, and the only person who could tolerate him... was himself. Even Emodao would be caught laughing at this weirdo. Then again, he was still one of his loyal servants; he wouldn't defect even if the push came to a shove. They had a lot of enemies not just heaven...
