The distance between the Li Palace and the Imperial Palace was not at all great.
It was just that with Chen Changsheng's current status, to enter the Li Palace was quite easy while entering the Imperial Palace was rather troublesome. This was especially the case given that he had not sent out advance notice. Ultimately, he still managed to startle Xue Xingchuan.
"What business does Principal Chen have in the palace so late at night?"
"I want to go and see Luoluo."
Xue Xingchuan had asked very casually and Chen Changsheng had responded even more casually. Thus, the heavily-guarded Imperial Palace opened its gates.
