The plan for the trio including Liu Xing to attack one at a time went up in smoke. They couldn't possibly crush each one at a time so they separated, one against one.
These three Grandmasters' cultivation level was high.
With a loud "bang", waves and waves of fist energy violently surged outward, causing sand to fly and pebbles to roll outside of the Imperial Residence. It was a dynamic display of strength. The surroundings were as quiet as the night, without the slightest movement.
There was already a crowd gathering within the walls of the Imperial Residence but no one dared to stick their heads out as the impact caused by a Grandmaster was massive and could easily cause collateral damage. Better to be safe than sorry.
The strange thing was that there wasn't a single Grandmaster in this crowd, only a few of the Scribes and maids. The Protectors were only of the lower ranks.
