At most, he could add a few words after the instance's mission, but he still couldn't change the mission.
Niu Ben had merely added a small part of the dialogue, leading Mu Rufeng and a few other Contractors to mistakenly believe that bombs had been implanted in their bodies.
As for Mu Rufeng's Clone, Niu Ben himself was no longer aware.
Honestly, if Mu Rufeng hadn't learned of Niu Ben's secret, then Mu Rufeng would have been in a passive position.
But now, it was Mu Rufeng who had seized the initiative.
After all, he didn't care about failing a mission.
A lost arm could be restored with just a bit of money, even more so nothing to worry about.
Secondly, it was about Niu Ben's plan.
Niu Ben's plan was indeed what Mu Rufeng had hoped for, to destroy the Clone Factory.
The Clone Factory might be a Level 9 Group Forces with multiple branches.
But Aoyama Farm was no less formidable, also a Level 9 Group Forces, owning multiple farms.
