Xia Chujian thought that if it were her, she would also be reluctant to use that precious Black Gold Round Hat Flying Vehicle and switch to an excavating robot...
She set aside those conflicted feelings and watched carefully to see what the young girl would do next.
She saw the young girl return to the Black Gold Round Hat Flying Vehicle and bring out something that looked vaguely familiar.
Xia Chujian could not recall what it was for the moment. She saw the young girl first toss a metal plate into the Deep Pit, then carefully pick up that familiar object, twist it as if opening a lid, and pour its contents into the Deep Pit.
She then put the lid back on and returned the object to the flying vehicle.
After coming back out, she had her Mecha fly into the Deep Pit again. She took out a rusty metal plate that was nearly corroded through, held it up to the sunlight, and examined it as if checking the results.
It was the very plate she had thrown down earlier.
The young girl nodded in satisfaction, then tossed the metal plate back down.
After watching her fuss around for a while, Xia Chujian guessed she was tired too and returned to the Black Gold Round Hat Flying Vehicle.
Only then did Xia Chujian maintain Stealth Mode and have her Mecha fly away into the distance.
Then, at the normal speed of a Second Generation Mecha, she flew back over in a wobbly manner.
That round trip took her nearly half an hour.
By the time she reached the coordinates Teng Hai had given her, a full five hours had passed since she had arrived.
That was precisely how long a Second Generation Mecha needed to travel a hundred thousand
