Qing Chi left Lu Changsheng's cave mansion.
Lu Changsheng calculated the time. It had been around three thousand years since he chose to accept the ultimate test of the Black Light Realm.
In other words, he was indeed still within the ten thousand year limit.
There were still seven thousand years left.
The ultimate test of the Black Light Realm was to perform a life transition using the Heaven Opening Technique within ten thousand years and successfully advance, which would mean he passed the ultimate test of the Black Light Realm.
Lu Changsheng was quite confident about this.
After all, Lu Changsheng still had seven thousand years left.
He also had a large amount of Hongmeng Qi.
With resources and time, was Lu Changsheng afraid of being unable to perform a life transition?
On this point, Lu Changsheng was not worried at all.
"It's better to first elevate the physical body to the pinnacle."
Lu Changsheng began refining Hongmeng Qi.
