This was a person specially instructed by Helen to be allowed in, and she even specifically told them to let him look around freely and not to follow him.
It should be known that even if other high-ranking officials from different departments wanted to inspect this underground production hall, they would have someone from their team accompany them throughout the visit.
On the one hand, to supervise and fear that the other party might accidentally damage these valuable machines, and on the other, to provide a popular science introduction about some basic knowledge of the artificial human production chambers.
So now, the target specifically instructed by Helen, even if he destroyed one or two machines, how to deal with it would have to be reported to Helen before she could make a decision. They had no authority to punish him.
At most, they could only "respectfully" ask him to leave.
