Lu Ping'an's "disappearance" did not stir up much commotion, because far too many advanced combat powers had gone missing, making it impossible to keep count.
However, the Courtyard was still functioning, and the local Trading Land continued regular operations, which was a subtle way of signaling peace... The Deity's Holy Domain and Divine Kingdom still existed, so It clearly had not perished.
Everyone knew that Lu Ping'an had already vaguely shown traces of divinity, and some were even surprised as to why he hadn't yet ascended to the realm of the Quasi-God.
When concerned individuals proactively came to inquire, a simple "currently in advancement" was a rather persuasive response.
In fact, following this victory, most professionals experienced leaps in their progression.
