Hidden Endings process from here
To achieve hidden endings, you need to collect 5 black books with numbers on them.
Two books can be directly obtained in the lab room.
1. One is on the shelf facing the center table, locating besides the door of the lounge.
2. The other one is in the right part of the glass cabinet, which is the cabinet of the green stone.

Three books need passwords
The first one
1. By setting the orange chip on the panel of A-013, you can get the public area password for A-013.
2. Set the public area password to open the public A-013 drawer, you can get a black book.

The second one
1. You can get a paper of experiment introduction with red notes from the first drawer of B-142, there is a sequence of numbers under the “infinite energy”.
2. In the left-bottom drawer of A-013, there is a cube matrix with a label “Infinite Energy Company”, the number sequence is showing which cube should be pressed for the matrix.
3. 13 means the cube of the 1st row and 3rd column should be pressed. Similarly, 24 means the 2nd row-4th column; 32 means 3rd row-2nd column, 34 means 3rd row-4th column.
4. Press the correct cubes and let other cubes be the situations of non-pressed, the board will open, and you can get a black book from the drawer.

The third one
1. You can take all things out from the second drawer of B-142, at the bottom of the drawer, there is a lock, and a hint paper.
2. You can get a related hint paper behind the chest of the yellow stone, which is in the bottom layer of the closed cabinet.
3. Based on the hint papers, the green frames show the situations that the chips are set on correct panels. On the other hand, the arrows and red frames indicate you need to set personal chips on incorrect panels.
4. Based on the triangles on the two hints, you can determine which correct one corresponds to incorrect one. That is, the orange chip should be set to the panel corresponding to the white chip, which is the panel of C-098. Similarly, you can set the grey chip on the panel corresponding to the blue chip (B-857); set the white chip on the panel corresponding to the grey chip (B-142); set the blue chip on the panel corresponding to the orange chip (A-013).
5. Then, you can get four connection numbers from the screens. Set these numbers by the order corresponding to each color written on the bottom of the second drawer of B-142, you can get the password. Note that here you should set the color by chips, not by panel. For example, the orange one with red frame is corresponding to the number obtained by setting the orange chip on the incorrect panel of C-098.
6. The password is 5912.
7. Set the password, then the third drawer of B-142 will get out. Press the button of the drawer’s board, the board will open, and you can get a black book.

After getting all 5 books
1. Set the book besides the trophies (2nd layer from top) by the order on the shelf in lounge. The order is indicated by the encountered paper or the books in the -3 dimension world, which is 4-2-1-5-3.
2. Then, the wall behind the shelf will open, you can get into the secret room of the lab.
3. At the bottom drawer in the secrete room, you can get a black chip.
4. Set the black chip on the panel of B-142, you can see the contents about conspiracies in the lab.

Then, you have a choice to decide the ending.
1. If you do not set the black chip on the panel in the corridor, after you set the extra staff key to open the machine’s shell, there will be two choices on the screen.
2. If you choose “Yes”, you are about to achieve normal ending. In this case, you still need to follow the steps to close the dimension change. But after you choose “Yes” and then you upload the file by setting the black chip on the port in corridor, you are about to achieve the ending 3.
3. If you choose “No”, you are about to achieve the ending 2. In this case, you are not required to close the dimension change, and after few seconds, you will achieve the ending 2.

Otherwise,
1.If as said in the black chip, you set the black chip on the panel in the corridor then open the machine’s shell, you are about to achieve the ending 3 without the choices above.
2. From here, follow the process of the step 4 of the stage 4 to close the dimension change, you can see different chat contents after that, and achieve the ending 3.
