Day 3: Chaos struck, and after the big bell chimed only a few times, the clock tower actually got stuck. There was no other way, so we returned to the main hall and found the little girl had appeared again, fiddling with a Rubik's cube. After a loud bang, the little girl gave us the Rubik's cube and then left alone. Soon after, we heard a scream, and Ken decided to go rescue him. Upon reaching the aerial corridor, we found the entire house had flipped upside down. Returning to the main hall, Ken decided to check the screening room first. On the way to the screening room, this area was also completely inverted (there was a blood-red number 740 here; its purpose will become clear later). After taking the 'machine oil,' we entered the guest room through another door in the main hall. Due to the inversion, there was still no way forward here, but by investigating the nearby ventilation duct, we could bypass this. This section switches to first-person perspective, where the arrow keys control reaching the other end's exit. Here we could get a 'Servant's Diary,' then enter the purple door. From this ventilation duct, we reached the display room. There was a monster here, but since we had no weapons, we could ignore it for now. On the other side, we found a chessboard; after investigating, we moved the Rubik's cube to the green square, ensuring that the cube's side facing up matched the square's color. Another shake occurred, then back through the ventilation duct—we had to hide in a dead-end before the exit. When we looked back, we saw the half-body zombie encountered on the second day's meat-washing scene crawl past. Ignoring it, we climbed out of the ventilator and returned to the main hall and then to the screening room through another duct (here we could get some 'lubricating oil' in the vent). Now the room had returned to normal. In the screening room, Ken found the big man was gone. Investigating the photo on the floor, we obtained a 'torn group photo, only half remaining.' Going back to the guest room by the same route, suddenly there was a ladder. We climbed it to the utility room. Passing through the middle, we saw a shadow descend the stairs. Investigating revealed a hole; don't go down yet. Exiting through another door in the utility room triggered a scene. A sword fell from above; follow the prompts with the arrow keys. After dodging the falling sword, investigating allowed us to obtain a weapon here. We could also find a 'Ram's Horn' here. Going to the display room, attaching the 'Ram's Horn' to the missing corner of the display revealed a safe. Entering the previously seen three-digit number 740 resulted in obtaining 'an old incomplete group photo' and 'attic key.' Going back to the utility room, we jumped down through the hole to the 1st-floor utility room, where we found another chessboard. Placing the Rubik's cube correctly according to the rules allowed us to exit (there was also a bottle of 'tranquilizer' here). Upon exiting, we found the entire corridor inverted. Entering a clock, we saw a servant mysteriously die while mopping—this was actually an invisible monster. We shouldn't rush in yet. Investigate the fallen clock and then use the 'lubricating oil' in the inventory. As long as the clock was struck, the invisible monster would be destroyed. Time to collect items: first, from the servant's corpse, we could get the 'wardrobe key'; then from the scene on the windowsill, we could get the 'changing room key'; and next to the storage room, we could find a 'lighter without oil.'Another hole was discovered in the corridor next to the changing room. Jumping down from here leads to the tool room. After obtaining the 'Servant's Diary 2,' push open the box and enter the ventilation duct to return to the guest room, then head to the open-air balcony, where you can get the 'Sedative' along the way. To the left of the open-air balcony is a pile of weeds. Interact with it to combine the 'Lighter without Oil' and 'Machine Oil' to get the 'Lighter Filled with Oil.' Using it allows you to obtain the 'Withered Stone Plate.' You can climb onto the top of the open-air balcony from the statue. Use the 'Withered Stone Plate' to complete the half stone plate to start the Rubik's Cube game. After solving the Rubik's Cube, we return to the previous 1F corridor through the ventilation duct, enter the changing room (there is a servant inside), and after opening the wardrobe, we can see the stone plate. First, deal with the servant who rushes in. Then place the Rubik's Cube properly and return to the 2F via the staircase room, now allowing access to the aerial corridor. After the events on the aerial corridor, we enter the rooftop from the balcony. Enter the small wooden cabin and climb the ladder to continue through the ventilation duct. After exiting the ventilation duct, save at point S first, then rush straight to the stairwell. There is an invisible enemy here, so make sure to enter the 3F stairwell before it appears. Upon reaching the central part of the stairwell, a servant will appear from each of the two doors. Quickly deal with one of them first. Go through the stairwell door to the attic, then an event occurs where the huge man appears again, covered in blood. This time, a true BOSS battle begins. The BOSS is very simple; initially, walk around him to lure him to attack with both hands, then attack him during his stiff moment. Afterwards, he will start to smash around; just keep a distance, watch the direction of his attack, dodge, and strike him from behind. When he falls, go up and press the attack button, and follow the prompts on the directional keys to subdue him. Finally, after defeating the huge man, a 'Clock Tower Key' can be found beside him. Then we return to the clock tower and find a little girl at the door. On the third chaotic day, Kent finally recalls memories about the little girl, Kate.
