Reconnaissance
A few days passed as Rui continued gathering as much data as possible. Although the first day more or less gave him everything he wanted, it was still better to get a sense of the routine before he made his move. He had evaluated all possible means of entry and had segregated them by the probability of success.
The least viable solutions were forceful entry either via brute force or stealth. He explored all possibilities, and it just didn't work.
Falsifying authorization was also too murky. He would need to somehow gain authentic documentation and security clearance. Furthermore, if they had any rigorous verification protocols, he would be screwed. Fooling those protocols was above his pay grade and far too removed from his capabilities as a Martial Artist.
