Bai Pu certainly wouldn't leave such a big oversight; he had already looked into it.
"Even if I advance to the high level, I can still enter the mid-and low-level Spirit Realm Plane where you are through the Source Lord's Descent. However, my level will be restricted."
When Bai Pu's level is restricted, it means that upon entering the low-level and mid-level Spirit Realms, his level will match the highest level allowed by that world.
Generally, the limit for low-level Spirit Realms is Level 3 (except in Heart Demon: Oath, and other worlds), and for mid-level Spirit Realms, the limit is Level 6.
However, Bai Pu's Combat Specialization and Skill Level will not be restricted. Perhaps it's a hidden trait of the Limit Breaker title.
After the "meeting" concluded, Bai Pu met with the Blood Spider returning from hunting monsters.
"I'm planning to challenge the Professional Plane."
This wasn't a discussion but rather Bai Pu's decision being informed to his teammates.
