The Water Nourishes the West River in the Wandering on the River of Oblivion is a brand new activity that involves constructing and replacing water channels, planning the diversion and confluence of water flow, and guiding the distribution from the inlet to the outlet. It unfolds based on the story of Li Bing's water management, and many players are unsure how to play it upon their first encounter. Below, we will introduce the rules of this activity so that everyone can successfully manage the water and obtain generous rewards.

Firstly, we need to understand the water channels, which serve as the pathways for the water, connecting the inlet to the outlet and guiding the water. There are two types: straight and curved. Straight channels have two attributes - width and capacity. The capacity determines how much water the channel can handle, while the width affects the proportion of the water flow. Curved channels do not have these two attributes; they are used to change the direction of the water. In each level, there are pre-existing water channels, and you also have channels in your inventory that you can place. You can put the channels from your inventory on empty plots or replace the existing ones directly.

Next, there are the inlets and outlets. The inlet is the starting point of the water flow, and each level may have one or more inlets, with each indicating the amount of water flowing out. The outlet is the endpoint of the water, and similarly, there may be one or more in each level, each marked with its capacity. To pass the level, you need to connect the inlets and outlets through the water channels, allowing the water to flow smoothly to the outlets and meet their capacity requirements.

Finally, there is the terrain, which has elevations, allowing water to flow from high to low. The terrain in the levels is typically higher in the upper left and lower in the lower right, meaning the water always flows from top to bottom and from left to right, and under no circumstances will it flow backwards. These three mechanisms form the basic gameplay of the levels. Once you understand them, you'll be able to handle some simpler levels with ease. However, when faced with complex levels where the water flow from the inlets does not match the capacity of the outlets, you will need to use diversion and confluence to pass the level.

Diversion and confluence mean that when a single water channel cannot handle all the water, or some outlets cannot handle the water flow, you can plan the water channels to change the water flow. For example, diverting the water flow from a straight channel through a curve or special plot to multiple different straight channels is called diversion. Merging the water flow from multiple straight channels through a curve and special plot into a single straight channel is called confluence. Using these two mechanisms, you can better navigate through difficult levels.

Above is an introduction to the Water Nourishes the West River gameplay in the Wandering on the River of Oblivion. In short, this gameplay involves constructing water channels to guide the water flow smoothly. Once you understand the above rules, carefully plan, and try different approaches when encountering obstacles, you should be able to pass the levels smoothly.
