There were many factions more powerful than Great Qin outside the Legacy Lands, so Zhao Fu wanted to act more low-profile in order to avoid showing too much of his power. If he was attacked by many other factions, things would be quite bad.
In actuality, allying with other factions to attack others was quite good. With how weak the Lelai Kingdom was right now, it was the best choice.
Later, Zhao Fu would spread news that the Lelai Kingdom had obtained nothing, as the Blue Wolf Kingdom's Queen had relocated the Royal City and left already.
After doing all of this, Zhao Fu grinned and continued to give the order to quickly retreat and leave this place.
Following this, the three Kings arrived and saw that it was just an empty City, making them feel quite furious. One of them was angry to the point that he started launching attacks everywhere, destroying the City.
