## Description

**Level Math 4** is the fifth level of the numerical chambers, appearing as an infinite expanse of yellow and green concrete plains. When digging downwards, the alternating pattern of yellow and green concrete continues infinitely. At an altitude of -x meters, the color pattern follows the rule as shown in the image on the right.

In this level, there exists the highly valuable "Infinity Chocolate," but the types and levels of danger of the entities in this level also increase. It is advised to bring a chair from Level Math 3 to use as a weapon.

This level contains a table where the Infinity Chocolate and other resources can typically be found.

## Entities

### Infinity Dictionary

This entity appears as a dictionary measuring \(10π\times\sqrt{500}\times e\) centimeters from the outside. However, upon contact with any human or entity, the "Infinity Dictionary" absorbs them into a white space, gradually "digesting" them into a word from the dictionary. If the dictionary is opened with a chair from Level Math 3 or another metal object, it will transfer knowledge related to the posterior chambers or numerical chambers into your mind. Each page of the "Infinity Dictionary" displays Koch snowflake-shaped patterns in the smallest font size (7px), printing vocabulary and its explanations. The first page of the "Infinity Dictionary" prints words like "A," "AA," "AAA," and so on, while the last page consists of a vocabulary composed of an infinite number of the character "ZZZZZZZZZZZZZ...ZZZZZ," indicating that the internal vocabulary is arranged according to the phonetic order of Chinese characters.

It is advisable to wear gloves when handling this entity.

### "Hilbert"

This entity resembles a middle-aged man and can answer mathematical questions related to infinity or fractals. Sometimes it may invite and teleport you to Level 69.

### Double Balls

This entity appears as two white spheres with a radius of 10 cm each and is the most dangerous entity in this level. When a wanderer stares at this entity continuously for 2 seconds, the "Double Balls" will undergo a repeating process of merging into one ball and splitting into two balls, similar to the Banach-Tarski paradox, and execute mental control in this manner. Controlled wanderers suddenly become addicted and seek out the "Infinity Dictionary" for contact (strong-willed individuals can resist), leading to being "digested." If accidentally seen, it is recommended to immediately close your eyes and use a chair to strike the entity, with a 60% chance of killing the "Double Balls."

## Outposts and Waystations

### Aleph Organization

* Friendly
* Open trade using Infinity Chocolate as currency
* Consists of 2-6 people

#### M.E.G.Math Chocolate Base

* Affiliated with M.E.G.Math
* Friendly, open trade
* Regularly recruits "distributors" to distribute "Infinity Chocolate" to other wanderers
* Currently has approximately 300 people

### Concrete Collection Organization

* Friendly
* Currently has 8-12 members
* Regularly collects minerals and concrete

## Entrances and Exits

### Entrances

* Tossing a π-shaped object at the "tan" or "cot" entities in Level Math 3 will transport you to **Level Math 4** after a few seconds.
* Chatting with "Hilbert" in Level 69 and bidding farewell will bring you to (or back to) **Level Math 4**.

### Exits

* As mentioned above, "Hilbert" can take you to Level 69.
* Killing 10 or more "Double Balls" will lead to Level Math 5.
* Spilling concrete tea onto the ground and jumping into the moistened ground in **Level Math 4** will also lead to Level Math 5.
* If one's willpower is strong enough, it is possible to directly extract the lifeless ball from the "Double Balls" entity (grabbing the entity's arm) 20 times to access a random level.
