放在左边这个柱子上打开绿光。
Put it on the left column and turn on green light.


出现木门，此时进去获得结局2。
'wooden door' is ending2.

再次回到游戏，找到下面这个东西。
Back to game again and find the following thing.


放在右边的柱子上打开蓝光，这次不需要用到结局2的道具。
Put it on the right column and turn on blue light, we don't need to use the cube used in ending2.


门是和结局2一样的木门，进入获得结局3。
The same 'wooden door' with ending2, we get ending3.

最后一个结局，把结局2和结局3用到的道具都放好，打开绿光和蓝光。
Last ending, use both props used in ending2 and ending3, turn on green light and blue light.

但是发现绿光和蓝光前面的挡板不能同时放下来，只能放一个，这里把绿光挡板放下来。
But we find that the two boards in front of the two light can't be put down at the same time. We put down green side.

然后蓝光挡板上有个螺丝可以扭掉，这样绿光和蓝光就能同时存在。
Blue side, there is a screw can be loosened, then the green light and blue light can exist at the same time.



场上同时有红绿蓝三种光后，出现一扇看上去很混沌的门，进入获得结局4。
If there are three kinds of light, a 'chaos door' will appear, we get ending4.




以上4个结局全部达成后获得最后一个成就，全成就达成。
After all four endings, the last achievement will jump out. 100% lol
