The Space Station isn't exactly small, but Chen Ming is controlling An Wuping, who could overpower the Space Station on his own even if transformed, within a short period.
Attempting to do so and safely preserving some information from the Space Station would be extremely troublesome. Forcefully using Spiritual Energy to prevent data deletion would be more likely to expose the connection between An Wuping and Chen Ming.
It's quite a headache.
If Chen Ming's purpose this time was merely to destroy Zuo Jing's Space Station, he could have started taking action earlier.
But he is here to gather more clues about Zuo Jing, so he can't proceed that way.
He needs to be fully prepared before taking action, at least first understanding the general situation of the Space Station.
Luckily, his spacecraft maintenance is estimated to need another week, considering how thoroughly damaged it is.
He still has time.
