Shen Zha rattled on and on, his attitude was exceedingly sincere, clearly very eager to collaborate with Jiang Ning again. However, Jiang Ning was ultimately not an insider in the circle; she wasn't bound by any contract, nor did she have a team to maintain, free as a commoner with complete autonomy.
Moreover, no matter how appealing Shen Zha's words were, Jiang Ning hadn't forgotten the last time she participated in "Survive for 30 Days" and was tricked by the production team.
Before the program aired, the team didn't reveal any information about the hologram, this deliberate concealment—even if Jiang Ning managed to clear her name through the program—didn't cause her to feel any gratitude towards the production team.
Not pursuing the production team's responsibility for the concealment was already her biggest concession.
