With the pneumatic body, the qi was condensed, and at the moment of life and death, Lin Ye burst out of his whole body potential, only to see a black shadow flash, and in an instant, he had already come to an unbreakable door. Looking up, on the door reflecting a faint metallic luster, there were several large black letters, SCP-233, Keter.

This is yet another Keter-class object, and this one is far more dangerous than SCP738. However, now, there is no time left for Lin Ye to think, because, although his speed is so fast, almost at the same time as he reaches the door, the surrounding light has begun to dim, and at the same time, less than ten meters behind him, traces of corrosion have also begun to appear, all of which shows that SCP106 has been spatially strengthened in all aspects, and basically has no known weaknesses......

However, although he was already in such a crisis, Lin Ye's face still did not have a trace of fear, and on his face as white as jade, there was only extreme calmness. He silently cast a spell on himself that he had just learned from the Law of Primordial Darkness, and without hesitation, he flew into the door.

[Item No.: SCP-233.]

Object Class: Keter

Special Containment Procedures: SCP-233 is to be kept in a 23x23x23 concrete-lined cubic containment enclosure, 23x23x23, regardless of unit length. A 23-meter security zone has been established around the object: no D-class personnel who are not 23 years of age are allowed to enter the security zone. For research convenience, it is best to use D-class personnel who have their 23rd birthday before the end of the month. Firearms of any kind are strictly prohibited in the area, unless they are using special .2323 caliber ammunition. Staff shifts must be scheduled for 23 hours on the hour, and the last shift must be accurate to 23:23 GMT.

Ammunition of [REDACTED] mm must never be used, and D-class personnel born in the month of [REDACTED] or in the month of [REDACTED], [REDACTED], or twenty [REDACTED], or any [REDACTED] are to be brought to within 23 meters of the safe zone. Personnel at the containment facility are to be specifically reminded to be especially vigilant about [REDACTED] time sharing on the hour, especially at [REDACTED], when the SCP is at its most active. As a matter of optimality, all personnel are to be evacuated outside the 23-metre safety zone at this time.

Description: SCP-233 is a 23-sided body, each of which is an equilateral rectangle with a straight line inside. Due to the strange spatial nature of the object, it is impossible to imitate the exact configuration of the object in 3D or 2D.

SCP-233 has the singular property of altering the laws of nearby mathematics, causing the surrounding counts to be completely incorrect, unless the base 23 system is used. However, a calculator using base 23 would benefit from the SCP: it would perform calculations at 23 times the normal speed, so the proposal to destroy the SCP was postponed due to the possibility of integrating it into [DATA EXPUNGED]. Because of the difficulty of converting binary to 23, the device has shown its value to the organization (sic: the Organization). (See Dr. Nana's [REDACTED] Report 234 [REDACTED] about her "unusual solution" to unified field theory.)

Unfortunately, the presence of the number [REDACTED] within its safe zone causes SCP-233 to exhibit extremely violent effects (see Report: Dr. Nana [REDACTED] Death in [REDACTED]). Everything affected by its effects will be chemically split rapidly: direct contact will cause the contact to collapse instantly, as its constituent atoms will collapse instantaneously within 0.23 seconds.

It is important to note that it appears that SCP-233 is not triggered by the physical properties of the object it touches, but rather by the perception of surrounding observers. For example, it is safe to hang SCP-233 from a 2.74 meter long pole, as long as no observer in the danger zone knows that the pole is in fact [REDACTED] feet long. The cause of this effect is unknown, but it may be related to the "observer effect" in classical quantum physics.

Addendum 233-a: According to A. A. At Dr. Clef's suggestion, the object's research team requested that the object be renumbered as SCP-2323, and while this may lead to an SCP designation that is out of the norm, its mathematical nature requires us to be as careful as possible with all data relating to it, including documentation related to it. During Incident [REDACTED], the object accidentally came into contact with a [REDACTED] volt battery, which was brought in by an employee for use with his music equipment, causing the object's range of effect to suddenly increase by approximately 100000 percent and to 232.32 km, resulting in the death of a nearby AAA baseball team (the game was going on until the inning of [REDACTED]), and all nearby numbers associated with SCP-233 were [REDACTED] The computer archives were destroyed. For the safety of all personnel, in any future it is to avoid altering the number [REDACTED] to associate SCP-233 with it.

Addendum 233-b: Pregnant female employees are never to be allowed in the safe zone under any circumstances. 】

Obviously, this is a very dangerous SCP, as stated in the SCP Foundation setting, once it is triggered, then if there is an "observer" within a radius of 23 meters with the sphere as its center, then within this radius, any person or object containing the deleted value will be eliminated within 0.23 seconds. Of course, in this area, there is already a "observer" such as Lin Ye who knows its characteristics, in other words, this space has become a place that can be destroyed at any time, although the SCP Foundation does not explicitly give what the deletion value is, but Lin Ye has deduced that this number is 9 based on the value of 2.74 feet, and what is even more terrifying is that there is a characteristic on Lin Ye's body that will lead to deletion......

However, the location of this SCP is clearly different from that of SCP. Such a dangerous object, not only is there no safety zone nearby, but there is not even a security officer, although this is a secret passage, but it is impossible to be in such an undefended state. What's more, this SCP has a lot of value for the Foundation, and it will often be used for experiments, so there are big problems with how to look at it. Then, after all the impossibilities have been eliminated, there is only one truth......

However, after Lin Ye rushed into the room, SCP233 in the center of the room began to emit a glowing white light, and at the same time, large areas of black corrosion began to appear behind him, and it was clear that SCP106 did not give up its prey, and followed him into the room.

There is a dead end in front and a chasing soldier in the back, why did Lin Ye throw himself into the net? How sure is he? What secrets are hidden behind that door? Is it a dead end, or is it a life?
