Shang continued training against the Abomination Lords for several more centuries.
Luckily, nothing of note happened within the next 700 years, but that wasn't necessarily a good thing.
The other Empires were rarely using Peak Mage Lords, and when they did, they only sent out average ones.
Naturally, the Lightning Manor could easily deal with these weaker Mage Lords.
The problem was that the war was going too smoothly for the Lightning Manor.
After years and years of barely being able to survive, the Lightning Manor could now defend itself easily, and the population of their Ancestral Mages was starting to increase again.
All of this was thanks to Shang since he had dealt with the most troublesome opponents and made it impossible for the Empires to send any powerful Peak Mage Lords into battle.
