Also, this kind of talisman paper could only grant immunity to low-level true damage. Zhao Fu's Killing Heart Sword directly annihilated souls, so this talisman paper could not take effect. Anyone killed by Zhao Fu's Killing Heart Sword would still die.
Faced with the grand setup they had laid around Great Qin, the question now was how to break the deadlock. Zhao Fu alone could not do it, so he could only discuss it with the many great generals.
If they could not attack the four nations now, they could turn around and attack in the other three directions instead. One option was to swallow the remaining two regions north of Huaxia, then expand east and west, sealing the four nations within.
It would then be much easier to deal with them. With Great Qin's national power forming the barrier, no one could travel freely to and from the four nations. They would be isolated and naturally much easier to resolve.
The second option was to directly take control of the central region—the heart of Huaxia—bringing the number of regions to one thousand. After controlling those thousand regions, they could attack east, west, and south, first unifying Huaxia before anything else.
After all, the other small nations posed almost no pressure on Great Qin and could be easily cleared away. Yet every time, it was Huaxia's internal forces that placed the greatest pressure on Great Qin; everything was connected to them. They were Great Qin's greatest obstacle.
As long as this greatest obstacle was removed, Great Qin's path ahead would naturally become much smoother. What ability would the remaining forces of the Central Continent have to contend against Great Qin?
This was in fact also an excellent method: clear out the internal resisting forces before dealing with the external ones.
