Creating a farm for Yazhen Syringes in Wuling City is a great way to handle your outpost and get more Wuling Stock Bills. This setup makes healing items that you can sell or use to get back 320 HP every second.

This guide explains how to make Yazhen Syringes, but you can change it to make Jincao Drinks or other liquids by just switching the plants you grow.

Core Materials and Power

You need a steady flow of Ferrium Ore to start. Set up mining rigs on the nodes in the northern part of the map and link them to four Depot Unloaders in Arknights: Endfield.

For power, you can use a Xiranite Pylon or a regular Electric Pylon in the middle of your machines. You also need one water source. Use a Pipe Splitter to send water to both your plants and your machines.

Building the Assembly Line

Put four Depot Unloaders on the left in two pairs with a small gap between them. Set them all to pull Ferrium Ore. Place a Refining Unit in front of each one to turn the ore into Ferrium. The bottom units should lead to a Molding Unit to make Ferrium Bottles.

Since the Molding Unit needs two pieces of Ferrium for each bottle, use two lines to feed it. The top two units should go into Fitting Units to make Ferrium Parts. Put a Packaging Unit at the end where the bottles and parts meet to make the syringes.

Setting Up the Liquid Production

You need a Filling Unit and a Reactor Crucible to put the medicine in the bottles. Place the Filling Unit above the Molding Unit so it gets the empty bottles in Arknights: Endfield.

Put the Reactor Crucible above that. The crucible takes water and Yazhen Powder to make the liquid. When the liquid is ready, it goes down to the Filling Unit to fill the bottles. These are then sent to the Packaging Unit to be finished with the Ferrium Parts.

Creating the Infinite Plant Farm

The most important part is the loop that makes more plants. You need a Seed Picking Unit and a Planting Unit.

Connect them so seeds go to the planter and grown plants go back to the picker. Put Yazhen flowers in the Seed Picking Unit to start.

The seeds go to the Planting Unit and grow with water. Take the extra plants and send them to a Shredding Unit to make Yazhen Powder. Send that powder to the Reactor Crucible to mix with water.

Customizing the Farm

You can change what the farm makes very quickly. To make Jincao Drinks, put Jincao plants in the Planting Unit instead of Yazhen in Arknights: Endfield.

The system will start making Jincao Powder and Jincao Solution on its own. You can also make Xiranite Solution by piping liquid Xiranite into the Reactor Crucible instead of using the plant shredder.
