There is a light puzzle in resident evil 5 No.3 Middle School to No.2 Middle School. How to turn the mirror to by going up one flight of stairs?

In short, it is to refract light to the last organ, which looks like a mirror. The first thing to judge is the source of light, which comes from a pillar. Also, the refraction angles are all 90-degree right angles, so we just need to judge whether to turn left or right, which is very simple. This ensures that the direction between the mirror and the light is only 45 degrees. Another thing to note is that even if you know how to turn, you should pay attention to wait until your partner runs to the high platform to avoid manslaughter. In addition, if you open the box in the middle of the third floor, a large number of small spiders will come out; In addition, there is a secret room on the third floor, which needs light on the beads in the mouth of the statue to open; Finally, after turning on the mechanism, be careful not to be too close to the lights in the passage, which is easy to touch. It's best to walk slowly and adjust before running.
