Jia Yan observed his surroundings without much action, then began reading a warning sign beside him.
"Notice, the maximum stay in this area is fifteen minutes, and for the physically weak among the strong ones, no more than ten minutes. So, please quickly take the stones and leave without any hostile actions, otherwise the automatic system will shoot to kill with no responsibility taken!"
From this warning sign, it was clear that the area was definitely protected, and the defense was no simple matter.
Having read the sign, he went on to collect as usual.
Standing at the edge of the one hundred and fifty-meter zone, everything around Jia Yan was artificially constructed, while the exposed ground within that area might just reveal the true face of this small celestial body. However, on this entire planet, such a scene was no longer visible from the outside; to others, it appeared only as a bizarre, smooth celestial body.
