After much thinking, Mark decided to rush his plans too.
First of all, he cannot keep Shang Jiao hostage for too long. He never knows if Lan Jingyi suddenly loses her patience.
Secondly, there is a high chance that things might get cool down if he gives too much time for Phoenix Empire to recover.
Before he left, he did hear of the announcement made by the Emperor. Mark assumed it might be because of his allegations but he didn't have any pity for his biological father anyway. In fact, he thought this is a perfect opportunity.
For the civil war to happen, Shang Zexi cannot win the race at all costs. But, he cannot lose by extreme either. The crown prince should feel like he has a strong chance.
As long as he loses by a tiny margin and Shang Wei ends up being a winner, Mark felt like he could support the crown prince in the shadows through funding and breaking up the military.
