In fact, strictly speaking, 'Hao Yi's actions fulfill Li Cheng's expectations.
If 'Hao Yi' directly started with a sentence, 'Sure, I can help you.'
Li Cheng's reaction wouldn't be: Great, great.
Rather, 'This person has issues, hidden motives.'
That's why He Ao deliberately raised some slightly excessive but not boundary-crossing demands.
Hao Yi is also 'B-level,' from this perspective, his desire to observe the promotion ceremony is quite reasonable.
He may harbor malice, or perhaps not.
Combining Hao Yi's previous series of actions, overall, he leans toward the Main World, so after considering, Li Cheng is very likely to accept this proposal.
From Li Cheng's perspective, he would also believe that Hao Yi's proposal is sincere, observing the promotion is indeed Hao Yi's goal, not hiding other intentions.
At the same time, he would believe that Hao Yi's offer to explore the research facility together is out of goodwill.
