In actuality, even if they did not attack, after clearing out the regions, Great Qin would make a move against the rest of China. After all, Great Qin would already be a Level 10 or so Marquisate Kingdom, and it would be no problem to destroy the rest of the Chinese factions.
Great Qin now had 14 billion people and 1.4 billion soldiers. This meant that Great Qin could now have 14,000 Basic General Seals, 1,400 Intermediate General Seals, 140 Advanced General Seals, and 14 Marquis Seals.
It also had 22,000 Great Cities and 4,521 Cities. At the same time, it also had countless Wyverns and Corpse Soul Commanders who had fused with City Lord Seals.
All of this together was a terrifying force. However, because the situation within Great Qin was not stable yet, Zhao Fu did not want to make a move. After completely clearing out all of the regions, Great Qin's overall strength would increase by leaps and bounds, making it much easier to take down the rest of China.
