23 hours later.
As Daneel walked out of the Central Tower while holding the key that was about to completely turn black, he couldn't help but bite his lips with frustration.
Each and every part of his body was aching, and he even had a very bad headache due to constantly changing camouflages and having his mageroot overly taxed for quite a long time.
Using various disguises, he had searched through almost every nook and cranny of the entire Central Tower, save for the core spot on the ground which the system couldn't infiltrate into, and a few other places.
Besides, he knew that there was probably nothing there except the core control mechanism of the formation, which was actively in the possession of someone.
At least three times, he had had very close shaves where the person he was disguised as had almost walked into the room he was in and realized that there were two of him.
