Dream of the Red Chamber is renowned for its exquisite literary art, profound character descriptions, and rich cultural connotations, and is considered one of the greatest novels in Chinese literature. It represents the peak of Chinese literature, integrating various literary forms such as poetry, opera, prose, and poetry. Its connotation is only rich, naturally forming a vast and colorful universe of Paul’s universe, but people’s understanding and perception of it are very limited. There may be many reasons, but the main reason is that traditional reading methods require high literacy from readers, which means that for people with shallow life experience and low literary literacy, they may not understand or appear boring (Figure 1). So, using modern and innovative means of expression, this great work is presented, allowing everyone to easily enter, experience, quickly perceive, and communicate with the characters described in the book at zero distance, or even transform into a certain character, experiencing the story described in the book, which is the Metaverse of Dream of the Red Chamber. The corresponding changes that are clearly foreseeable after the Metaverse transformation are also a powerful driving force for the birth of the Metaverse of Dream of the Red Chamber (Figure 2) [1] .

As a vast and complex system, the Metaverse must possess corresponding complex functions. Roblox is the first company to incorporate the functional requirements of the Metaverse into its prospectus. Roblox proposed eight key features of

the Metaverse, which are actually essential functions that the Metaverse must possess: Identity, Friends, Immersive, Low Friction, Variety, Anywhere, Economy, and Civilization. The same goes for the Metaverse of Dream of the Red Chamber. From initial design, to construction and implementation, to running testing and verification, efforts must be made to achieve these functions, thus presenting the fundamental characteristics of the true Metaverse [2] (Figure 3).

The space of the Metaverse of Dream of the Red Chamber consists of two main parts: the scenes described in the original works and the Redology (academic field devoted the study of Dream of the Red Chamber) Society Forum (a virtual academic forum for the study of Dream of the Red Chamber). There are many opinions in the academic and folk circles regarding the layout of the former, which is the scene depicted in the Dream of the Red Chamber. In addition, the description of the scene in the original works is limited to textual descriptions, which inherently leaves a lot of room for imagination. The research results of Redology that are most in line with the description of the original works Dream of the Red Chamber (Cheng Gao Edition) are adopted here (Figure 4). The latter is a virtual experience space constructed by developers based on the Metaverse ray of Dream of the Red Chamber (Figure 5), but there is actually no fixed sample [3] .

The Metaverse of Dream of the Red Chamber itself is in working condition at all times, and there are no frequent and complicated processes. What this refers to is the client’s entry into the Metaverse of Dream of the Red Chamber and the various tasks that are usually carried out after entry, and they need to strictly follow the prescribed procedures. Otherwise, either you will not be able to enter the Metaverse, or after entering the Metaverse, you will not be able to obtain full physical enjoyment and effective social interaction. Of course, you will not be able to obtain ideal economic benefits in the Metaverse (Figure 6) [4] .

The virtual reality elements of the Metaverse of Dream of the Red Chamber still rely more on the Unity3D environment and are imported from outside through interactive operations. After importing, it is usually necessary to perform secondary editing on these elements. For example, redefining image accuracy, defining animation clips, and so on. Orderly place the imported elements into the scene, configure the lighting, and define the corresponding parameters of lighting/environment. In this way, the most basic work of virtual reality in the Metaverse of Dream of the Red Chamber is basically completed.

The Metaverse of Dream of the Red Chamber is based on the content of literary works, with an artistic foundation that transcends reality, and therefore has an infinite space for imagination. However, this is not enough, there should also be a lot of freedom and diversity beyond reality. For example, spatial transfer, changes in perspective, diversity in the presentation style of interactive objects, and infinite related expansion of content [8] .

The immersion of the Metaverse of Dream of the Red Chamber includes two aspects: immersion and immersive experience. Starting from entering the Metaverse of Dream of the Red Chamber, everyone views the world from a subjective perspective (first person perspective), and is able to fully control their body and engage in various behaviors they want, just like being in the real world. This is the sense of substitution. In the real world, everyone is in a certain environment no matter when or where they are. Entering the Metaverse of Dream of the Red

Chamber also requires this feeling: always being in the world depicted in Dream of the Red Chamber.

The Metaverse of Dream of the Red Chamber is usually an online digital environment, so a stable internet connection is needed to support user interaction.

Socket.IO is a popular cross platform real-time communication library used to achieve real-time connections in internet applications. It is built on WebSocket technology and provides high-level abstraction and convenient APIs for internet connectivity. After installing the Socket.IO library, you can create a Socket.IO server. In Node.js, use the Socket.IO library to create a server:

const io = require('socket.io')(server);

io.on('connection', (socket) => {

console.log('A user connected');

Through Socket.IO for the Metaverse of Dream of the Red Chamber to prepare the network environment, but does not mean that you can immediately enter the network interaction state, but also need to in the Unity front-end application, the introduction of Socket.IO client library, in order to establish a connection with the Socket.IO server. After the successful connection, the Metaverse can really operate. Using C# as an example, the using Socket.IO Client directive provides access to Socket.IO client functionality, which can be used to establish a Socket.IO connection and communicate in real-time in C#. The library Socket.IO Client can help you establish a connection with the Socket.IO server and send or receive data [9] .

When the Socket.IO client application starts, it attempts to connect to the Socket.IO server. After a successful connection, the client and server can send messages and events to each other.

// Send the message to the server

socket.emit(‘chat message’, ‘Hello, world! ‘);

// Listens for messages sent by the server

socket.on(‘chat message’, (message) => {

console.log(‘Received message: ‘ + message);

});

On both the client and server side, you can define message and event handlers to communicate over the connection. For example, you can define an event to handle the sending and receiving of a chat message (Figure 8).

The Metaverse of Dream of the Chamber is an attempt to provide a completely realistic experience world, and a very important guarantee for this realism is low latency, that is, the speed of data from the client to the server and back again. The better the network status, the faster the server response; The smaller the number of users, the lower the latency. In games that require quick reactions, such as competitive and RPG battles, latency has a significant impact on the game. Technically, it is possible to control the number of people, coordinate the execution of transactions, simplify the presentation of data, and reference efficient algorithms or programming ideas [10] .

When entering the Metaverse of Dream of the Red Chamber, everyone will

receive a digital identity after successfully logging in, which corresponds to a digital code. This code is unique and scientifically and rationally designed. It not only follows the prevailing rules in the industry, but also meets the individual needs of the Metaverse itself. The code is composed of several intervals of legal characters, and each interval corresponds to a special meaning (attribute), such as the digital person’s occupation, gender, technical expertise, etc. As far as a single interval is concerned, most of them are not unique, but the final code formed after combination is unique. The encoding of digital identity is not freely chosen by those who enter the Metaverse, but is automatically completed by the Metaverse digital identity registration process. This processing is also to ensure the strict and orderly uniqueness of digital identity encoding. The principle of uniqueness of digital identity is crucial, and everyone who enters the Metaverse must strictly abide by it, because it is the prerequisite to ensure to orderly operate and manage the Metaverse (Figure 9).

Digital identity is a human attribute in the Metaverse and is concealed, so it requires a recognizable digital image, which is a digital avatar. A digital avatar is a digital person with unique characteristics. The digital human avatars in the Metaverse are characters mentioned in the book Dream of the Red Chamber or virtual characters exclusive to the Metaverse. However, the avatar is not necessarily exclusive to the identity corresponding to a certain identity code. In other

words, although the virtual identity code in the Metaverse is unique and is generally fixed for the life entering the Metaverse, the image corresponding to this identity may be different from the last time someone entered the Metaverse. It is different, and the image (digital person) may have been used by someone else before. This is different from the one-to-one correspondence between each person’s identity code (ID card) and physical body in the real world. However, this does not prevent each digital person appearing in the Metaverse of Dream of the Red Chamber from maintaining unique characteristics. Although the difference sometimes seems small, there is actually a difference. Digital avatars (digital people) are the basis for creating a sense of life and a humanistic atmosphere in the Metaverse, and are therefore the first step in building a complete ecology of the Metaverse.

The process of using the Unity + Socket.IO method to realize the Metaverse identity registration is: Unity completes the identity registration, and then Unity sends a request to save relevant information to the server-side Socket.IO. Socket.IO immediately saves the registration information in the corresponding data text (such as Json) on the server side after responding to the request. The purpose of login authentication in the Metaverse of Dream of the Red Chamber is to ensure the legality of the identity of the person entering. Only those who are legal can enter the Metaverse, which can provide relevant benefits and assign corresponding digital incarnations accordingly.

Following the above description on the implementation of the virtual identity registration function of the Metaverse. The client login operation is implemented by Unity. When the client operation is completed, a login information comparison request is sent to the server-side Socket.IO. After Socket.IO responds to the request; it immediately reads the registration information data text on the server side and compares the data. If the comparison is successful, the client enters the Metaverse; otherwise, a login error is displayed, and then the login UI is entered again (Figure 10).

Strict control of digital identity registration and login, such as avoiding duplication of registration information, input of illegal characters, etc., is a key technical guarantee and work link to ensure the uniqueness of digital identity.

The Metaverse of Dream of the Red Chamber realizes the management of virtual character identity information, including the addition, deletion, retrieval, summary, output and other aspects of related information. The addition of virtual identity is actually completed when the virtual identity is registered, and it is only listed and read in the information management UI, so other operations are

implemented in the information management UI. The UI is opened in two cases: one is automatically opened in the Metaverse according to the statistical results of the registrant’s activity index (for example, it is found that a registrant’s activity index is lower than the specified minimum activity index), and the other is opened regularly or irregularly by the Metaverse manager because of management needs [9] .

Technically, the above-mentioned virtual identity information management UI and related information management operations are all implemented by Unity. The reading of the original information, the completion of editing (the information management operation is completed), and the saving of the latest information are jointly completed by Unity + Socket.IO: Unity sends a request to Socket.IO for asking to read the corresponding text (such as Json) of the registration information, and Socket.IO responds and feeds back relevant data to Unity. After receiving the data, Unity will present it in the UI through format conversion. After the management work is completed, Unity sends a request to Socket.IO to save information. After responding to, Socket.IO saves the latest information in the relevant text (directly overwriting the original text) (Figure 11).

Establish an effective data management system, including collection, storage, processing and analysis of ecological information of the Metaverse of Dream of the Red Chamber. This can help monitor and evaluate the functioning of various parts of the Metaverse and support the decision-making process.

Ensure data security in the Metaverse of Dream of the Red Chamber and take appropriate measures to protect users’ private information. This can include security measures such as encryption technology, access control and authentication.

Comply with relevant laws and regulations, including data protection laws and privacy regulations. Establish data management and processing procedures that comply with regulatory requirements to ensure compliance with legal requirements during the data management process.

Establish good communication channels with the Metaverse community of Dream of the Red Chamber, understand their needs and feedback, and actively participate in community activities. This helps build trust and support and promotes a good community atmosphere and development.

Actively adopt new technologies and solutions, including artificial intelligence, blockchain and big data analysis, to improve the efficiency and effectiveness of the ecological information management of the Metaverse of Dream of the Red Chamber.

Enabling social interaction requires real-time communication technology and user interface design and exit management. Among them, real-time communication is handled by Socket.IO, and the user interface is implemented using Unity. Entering the Metaverse of Dream of the Red Chamber is not restricted by location. Everyone can use the terminal to enter and exit the Metaverse anytime and anywhere. However, the Metaverse will not let people exit easily, and there will be strict exit management: when the client behaves to exit the Metaverse of Dream of the Red Chamber (essentially exiting the Unity UI), Unity sends exit information to Socket.IO, and Socket.IO immediately implements the mechanism for handling disconnection will be started, specific events will be triggered, and the aftermath of client exit will be completed: client online information update, virtual identity avatar hiding, etc. [11] .
