Get the craftsman's key and the mysterious room 3 will be gone?

Next to the machine, take a key (where to put the wax canister) and put the wax canister on it. Go back to the basement, take the key to open the cabinet (cross socket) with six drawers on the left, and open the drawers in the order of flashing symbols to get the second coin. Go to the divination machine and get a handle for divination. Go to the greenhouse, make a phone call on the right side of the door, 1795 (press the number clockwise and let go to complete a digital dialing), put the handle on the machine next to you, go back to the library, pull down the switch to answer the phone, wait a moment and take away the wax tube, go back to the second floor and open your eyes and put it back, open the drawer to get the third coin and take a metal device from the divination machine. When the elevator goes up to the third floor, there is a mechanism for putting metal equipment on the railing next to the safe. Open a real eye, put it together and take it away. There is also a mechanism on the railing opposite, which frantically rubs the spherical surface above, driving the clock in the middle to hit the safe just now (the rubbing direction seems to control the swinging direction? Go back to the lobby and get the second blue crystal from the broken safe. In the greenhouse, the left wall of the door was dug with bricks. Open your eyes, put a keyhole on the adjusting mechanism, insert the key from the wall on the other side of the third floor and turn it. When it is useless, open your eyes and return to the key opening mechanism in the hole, then turn the key (180 degrees), then return to the second key opening mechanism in the hole and take out the fourth coin from the key. The first necessary prop of divination machine. Go to the greenhouse, enter the table on the left, put two blue crystals on the wheel, turn on the device, and follow the white arrow to get the second artifact. Then go back to the previous chapter and don't enter the door after the normal process. At this time, you can put the artifact on the left and right tables. After putting the artifact away, you have to open your eyes and turn on the organ. Then, only use artifacts to enter the end 2 (wooden door) of the left table, only use artifacts to enter the end 3 (wooden door) of the right table, and place artifacts to enter the ends 4 (chaos) on both sides. Special instructions: put the artifact behind the right table, remove the screw of the front baffle with a screwdriver and open the baffle.
