After more than 20 years of vigorous development, Chinese Internet literature has become a cultural phenomenon affecting the world. According to the data, China's online literature has spread more than 10000 works overseas, covering most countries and regions in the world. The international communication has achieved remarkable results. As a beneficial attempt of cross-cultural dialogue, online literature has become an important carrier for telling Chinese stories and spreading Chinese voices. How to deepen the overseas communication of online literature and complete the evolution from "going out" to "going in", we need to continue to make efforts in broadening the content and themes, improving the translation quality and achieving accurate promotion. In terms of communication content, the production of high-quality content is the core drive of "going out" of network literature. According to the data of Yuewen group, the compound growth rate of real-life themes of online literature in the five years from 2016 to 2021 exceeded 30%, ranking among the top five in the whole category in 2021. The network literature has transmitted a clear turning signal, and the trend of mainstream and fine works has been strengthened day by day. The subject matter of the network literature translated and introduced overseas has become increasingly rich, breaking the stereotype of focusing on fantasy, immortality and romance. To explore a new way for network literature to become a high-quality product, on the one hand, it should be rooted in real life, closely follow the trend of the times, and reflect the concerns of the people; On the other hand, it is necessary to root in Chinese traditional culture, enhance the storytelling and "network sense", open up the "pleasure channel" for overseas readers, and strive to win both praise and acclaim. In terms of communication effect, we should strengthen the translation link to make up for the shortcomings of "going out" of online literature. The overseas spread of Chinese online literature began in Southeast Asia, flourished in Europe and America, and gradually spread all over the world. With the trend of going to sea gradually becoming a scale and the spreading radius continuously extending, it is inevitable that "language barrier" and "acclimatization" will occur. In order to cross the communication barrier, the artificial intelligence company represented by twitter Technology launched the network literature artificial intelligence translation system, breaking the previous difficulties of slow translation speed, long cycle, high cost and few language types. The overseas portal represented by starting point international is paying attention to absorbing and training translators and editors from different languages, strengthening the construction of online literature translators, grasping the cultural communication context of different nationalities and regions in the world, and getting close to the cognitive map of overseas audiences. The combination of artificial translation and artificial intelligence translation may become a powerful guarantee for the "going to sea" of online literature. In terms of communication form, from the initial output of physical book copyright to the later promotion of foreign translation, from the multimedia communication of IP distribution to the mode "going to sea", the in-depth promotion of network literature "going to sea" highlights the tension of its cross media communication. China's unique network literature creation, dissemination, operation and cross-border distribution mode of IP content have been integrated into relevant countries and regions, forming a new mode of "ecological going to sea", providing new inspiration for the "going out" of network literature. To build a new ecological environment for the global cultural industry, it is necessary to strengthen cooperation with overseas industries, and expand the audience reach of the overseas market of online literature by using overseas high-quality communication resources. At the same time, we will make use of the technological dividend brought by digital media to launch the cross media products of online literature accurately and deepen the external communication of online literature according to local conditions. Continuously refining the layout of overseas industrial chain will also make the localized overseas operation mode more mature. Network literature, as the pioneer of Chinese culture "going to sea", goes to the world
