With its highly free江湖设定 (This part seems to be missing in the English translation, it should be: "With its highly free world setting, and gameplay that supports free trading, it has attracted many newcomers. Newcomers often have various things they don't understand, for example, the暗号功能 (This part seems to be missing in the English translation, it should be: "the code function in Go to the Rivers and Lakes. So, what is the code? This article will introduce and analyze it to help newcomers understand and use it flexibly during their adventures in the rivers and lakes. If you want to know, hurry up and take a look at the following text.")

The code system is, in simple terms, similar to a team-up function. When playing with friends, you can click on the code setting and enter a number between 100-9999. In a battle, each code will have its own unique color, and after successfully setting it, the player's name color will also change accordingly.

Players who set the same code cannot attack each other, and their name colors will be exactly the same. To attack someone else, your code must be different from theirs. In actual play, you can use this feature when fighting alongside friends or factions.

For example, when fighting enemies with friends, there might be area-of-effect attacks that could accidentally hurt teammates standing nearby. At this point, you need to set a code with your friends. For instance, you can set your code as 111 and inform your teammates of this code.

Have them set the same code as yours, so that during the fight, there won't be any accidental injuries, allowing for a more enjoyable team battle. Additionally, if you can't find your teammates, you can check the mini-map, where different colored names make it easy to distinguish quickly.

This concludes the introduction to the code in Go to the Rivers and Lakes. This practical feature allows us to avoid injuring teammates in the chaos of battle and helps to quickly distinguish between friend and foe through the color of names. After reading and learning about this, players should remember to utilize it during team battles to reduce unnecessary burdens in team fights.
