In the game Tread the Wind, while players are cultivating their realms, they should not forget to upgrade and expand their caves. The cave gameplay can also be understood as a home gameplay, where players can build multiple building modules within the cave to enhance their cultivation speed. This Tread the Wind building upgrade strategy is shared with friends, so that they can have a more forward-looking plan when constructing cave building modules.

The game also opens up the cave gameplay for players, allowing them to build multiple building modules in the cave. These buildings can help players quickly increase their cultivation. The size of the cave is also related to the character's realm; the higher the realm the character breaks through, the larger the scale of the cave, and thus the greater the storage capacity.

In the cave, players can set up an alchemy furnace to refine elixirs, with different elixirs providing different effects on cultivation enhancement; the herb garden can be used to grow herbs, which after successful planting, can be directly put into the alchemy furnace for refining; the Sky-reaching Tree is a module for producing wood and spirit stones, and the wood and spirit stones produced can be used for building upgrades; the Jade Void Immortal Stone is where immortal treasures are refined, and characters can equip these with immortal treasures, ancient treasures, etc.; the Storage Pavilion is essentially the player's backpack; the Treasure Gathering Spring produces resources for drawing ancient and immortal treasures; the Spirit Array is used to unlock array slots; the Workshop is for crafting rare equipment; the Cloud Piercing Ferry allows players to obtain supplies by transporting or plundering others; the Sword Control Platform is for refining weapons.

For upgrading these buildings, the main consumption is stone, wood, and spirit stones. Therefore, when upgrading, it is recommended to prioritize "Sky-reaching Tree" and "Storage Pavilion", one for producing spirit stones and wood, and the other for storing these item resources. However, during the upgrade, there will also be limitations based on the level of the cave itself.

To achieve rapid cave upgrades, it's important to master the cut-off time for resource gains from each section. This ensures that players can gain the highest benefits within the specified time frame, thereby accelerating the cave upgrade speed.
