Jiang Changsheng quickly thought of a way to make use of the Evil Lord.
First of all, he could not allow the Evil Lord to act recklessly in the Great Jing. When the Evil Lord entered the Great Jing and started to hurt people, he could capture the Evil Lord and force him to go to the hostile dynasties of Great Jing to absorb their strength. When he became stronger, he could come back and continue to challenge him, and the cycle would repeat.
Not only could the Evil Lord help Great Jing weaken the enemy, but he could also continuously provide him with survival rewards.
The more Jiang Changsheng thought about it, the more feasible he felt this plan was.
