Lu Yin selected the next video and continued watching.

This time, the display in front of him showed a dark room with a small stone in the middle of it. A man appeared and slowly approached the stone. However, before he even drew close enough to touch the stone, a burst of white light flashed out from above the man. A flurry of invisible attacks shattered the space inside the room, causing the man to crumble into pieces.

Lu Yin was shocked; this video was of a failed attempt. Lockbreakers faced major risks and many Lockbreakers died every year with death being a common occurrence in their line of work. It seems that the Sourcebox Catalog not only included successful cases, but they also featured failed attempts. These were actually even more useful than videos of successes to the average viewer, as these videos represented invaluable experiences.

Although no two sourceboxes in the universe were exactly the same, many shared similar traits and dangers. For example, Lu Yin had been terrified by that white flash that had appeared in this video; if, one day, he encountered a similar white flash during his own Lockbreaking attempt, he would make sure to flee immediately. These kinds of reactions were all born from experience. Hence, these videos were all very precious.
