Invitation

Abel did not continue to strengthen his territory in the dragon nest. Instead, he left the dragon island after the dragonoids were settled and the lightning territory had fully absorbed the top level gems.

He felt his heart relax as though a huge rock was lifted off him.

He turned back and gazed at the dragon island's world. He was not planning to ever go back again unless he had to.

He teleported back to the golden castle and soon went into retreat. 

In the next month, he basically spent his entire day battling. Although his rank or body did not level up, his territory finally gained some fighting ability.

All 3 of his territories reached the diameter of 10,000 meters, which was the limit of his current rank, and the sacrifice was 90,000 top level mana gems.

Still, that basically saved him 10 years of training.

If he wanted to level up again, he had to strengthen his wizard pattern, but there was no shortcut to this process.
