No one knows what exactly happened during the battle in Celestial Yang City back then; all that is known is that King Jingbei attempted a breakthrough to the Nascent Soul stage, White Tiger Mountain attacked, and then... the entire city inexplicably turned into a death city.
Not a single survivor!
The Golden Core Great Cultivator, White Tiger Master, and the Nascent Soul cultivators who supported King Jingbei back then all disappeared without a trace.
The Great Li Dynasty has investigated many times, but whether they have made any progress is unknown, as the matter is kept under stringent secrecy, with nothing released to the public.
White Tiger City, however, continues to operate, though it is rumored to have changed ownership, now under the control of the Great Li Dynasty.
...
Amidst the shifting winds and clouds, it seems everything has changed, yet nothing has changed at all.
