Assassinating Wu Balu himself wasn't difficult, escaping unscathed was.
At the outset of the war, both Chi Li and Yue Hongling had taken leaders' heads amidst their guards; back then, the defenses were sparse, akin to a one-on-one duel. But after a few assassinations by these two, everyone else became vigilant.
Wu Balu would either hide in the Beast Grounds, heavily guarded; or he would travel with a large army, with escorts front and back.
Decapitating him was feasible, but how would one escape from the encirclement of his army afterward?
Ba Tu believed that neither Yue Hongling nor Zhao Changhe could achieve this without exchanging lives, and Yue Hongling also thought she couldn't do it.
Such assassins were prepared never to return; Jing Ke had declared as much before he left.
The Human List was tough enough, but what about the Earth List?
