The clone looked at the lock on the staircase and after studying it for a few seconds decided that there was no way in hell he was ever breaking that lock.
There was a high probability that he could find the key somewhere in the library, most likely in one of the drawers of the librarian's desk, but in the end he decided to take the brute approach with 100% probability of success although it was a bit slower.
[ Giant Summoning ]
The clone summoned the 3 giants in the middle of the library and ordered them to start punching a hole through the roof.
The clone himself used [ Energy Blast ] and [ 9 Ashura sword slice ] to help the giants in the process as the three of them began relentlessly punching across the roof.
While the lock on the staircase was reinforced with some sort of magic, the ceiling wasn't and under the strength of the giants and the attacks of the clone, a hole was carved into it within 1 minute.
