**Item#: SCP-XXXX

Object Class: Euclid**

Special Containment Procedures: The SCP-XXXX is now contained at Site-19, and the room it replaced now was a SCP Foundation Class D's bedroom, with 50 meters long, 30 meters wide and 3 meters high. The SCP-XXXX moved to Site-19 at the date █████-███-███ and has not been moved since. As the room was occupied by SCP-XXXX, the Class D personnel who lived in the room had to change their dormitory. After 6000-alpha event, a room must be set up at the gate of SCP-XXXX to perform high-temperature erasers, and at least two experimenters should monitor SCP-XXXX continuously to judge whether SCP-XXXX-2 is generated or not. And three armed men stood guard with flamethrowers to prevent the SCP-XXXX-2 from escaping.

Description: The SCP-XXXX has been described as an entity similar to a normal room, and seen from the inside the SCP-XXXX is about 20 meters long, 26 meters wide, and has an almost infinite height. It can teleport to and replace any normal room, and after the SCP-XXXX leaves, the rooms it occupied will be restored to the original room. On the outside, the SCP-XXXX looks no different from the room it replaces, but no matter how big the room it replaced, the interior of the SCP-XXXX remains forever 20 meters long, 26 meters wide, and almost infinite height. The walls of the SCP-XXXX are made of a hitherto unknown and indestructible bluish-grey material, none of the existing durometers can be measured. If a human stays within the SCP-XXXX for more than about 100 seconds, according to the report of the Class-D, the top of the SCP-XXXX suddenly lights up with a beam of about 50,000 lumens and the walls begin to peel off and turn to ash(We also wondered why its walls would never be used up, since the amount of ash used to make an SCP-XXXX-2 is enormous.). When the ash accumulates to a certain extent (usually taking 3-5 minutes), they start to gather and result in the appearance of a humanoid creature made up of these ashes, which we named SCP-XXXX-2, which was described as a black humanoid creature between about 3 feet and 4 feet tall, with no features, it can take any shape it wants. Its density is unknown, weight is about 70 kilograms to 130 kilograms. This humanoid creature is hostile to any creature within the SCP-XXXX, usually by enveloping the target's head and choking it to death. After all of its targets die, it will try to leave the SCP-6000 and find new targets. Any attempt to move the SCP-XXXX-2 out of the SCP-XXXX has failed, but we can roughly judge that it does not have the intelligence. When there're no humans that are not present in SCP-XXXX, the walls will also slowly peel off to form SCP-XXXX-2, but this process that typically takes 12-15 hours. When SCP-XXXX-2 is generated, it will attempt to leave SCP-XXXX and slaughter any humans it encounters along the way. The only effective suppression method is high temperature. When SCP-XXXX-2 is destroyed, the ingredients of its body-the wall ash of SCP-XXXX will instantly be vaporized, leaving no trace.

Addendum: XXXX-Alpha: This event occurred in █████-███-███. The SCP-XXXX had just moved to the Site - 19 this day. Because of the workers of the Site-19 were not clear about the SCP-XXXX and the SCP-XXXX-2, when an SCP-XXXX-2 individual left the residential area, the Site-19 can't attack it effectively, causing the individual slaughtered all the way until the Site-19 in the boiler room, "death" because of the high temperature lead to structure damage. In this incident, a total of 27 people died at the Site, including 14 members of MTF, 8 experimenters, 3 workers, and 2 boiler room managers. After the accident, Site-19 updated the holding method in the management of SCP-XXXX, that is, setting up the high-temperature killing area. To date, the area has been functioning normally and the SCP-XXXX has caused no further casualties other than the Class-D personnel.

Addendum: XXXX-Bravo: At date █████-███-███, Dr.█████ applied for the interactive experiment between SCP-XXXX and SCP-682, the experiment title was "observe SCP-XXXX-2 perform obliteration of SCP-682", the O5 parliament passed the proposal. At the beginning of the experiment, the SCP-682 was tranquilized and then safely sent into the SCP-XXXX. SCP-682 woke up and kept making vague noises, presumably asking, "Where is here?" and was walking around restlessly. After 100 seconds, the strong light causes SCP-682 to express extreme anger and anxiety and started to roar at the infinitely high light source. When the SCP-XXXX-2 individual appeared, the SCP-682 pounce first and attacked the SCP-XXXX-2, but it was useless. At this point, the second SCP-XXXX-2 individual appears and attacks SCP-682 with the first SCP-XXXX-2 individual. Instead of enveloping the SCP-682's head in an attempt to suffocate it, they tried to drill into the body of the SCP-682 to attack. After three hours, SCP-682 seemed exhausted and lay flat on its face for nearly an hour without moving. The SCP-XXXX-2 also began to calm down, abandoning the SCP-682 as the target and attempting to leave the SCP-XXXX, which was then directly obliterated by the hot kill zone. Two Class-D entered the SCP-XXXX and within one minute checked the body of SCP-682 and injected tranquilizer. The SCP-682 was then removed by machine from the SCP-XXXX and returned to its original holding area. During this period, SCP-682 remained motionless. Twenty minutes after he returned to his holding area, he regained consciousness and became so angry that he tried several times to escape, but failed.
