Return to Dijiang
Start the mission by opening your Maps, and accessing the OMV Dijiang. Use the base's TP Point in the Bridge. Approach the marker in the area.
Ask Xaihi About the Upgrades
Move towards Xaihi and talk to her. She will inform you that the Control Nexus upgrade preparations have been completed.
She follows that the improvement will unlock the Manufacturing Cabin upgrades, allow tune system controls, and improve work performance.
Upgrade the Control Nexus
To upgrade your Control Nexus, you must first complete three materials, which are the Aerospace Material I, T-Credits, and the Algorithm Expansion Chip itself.
Open the Control Nexus button and select Upgrade. Once done, head back to Xaihi, and she'll let you know that a Growth Chamber can now be constructed at the Dijiang's Working Sector.
Construct Growth Chamber
Move to your next objective at the Growth Chamber. Follow the marker, and you will see the Growth Chamber on the left side of the hallway.
Press the Construct button to see the upgrade overview, and you'll learn that this chamber can cultivate various progression materials. For the construction itself, you will need three Aerospace Material I. Press Construct again to finalize the chamber.
Cultivate Any Material in the Growth Chamber
After construction, the Growth Chamber I room will open up. You will need to cultivate any material that is mostly derived from Seeds.
Grow Your Materials
| How to Cultivate Materials in Chamber | |
|---|---|
| 1 |  Approach the interface inside the room. This will allow you to press View Growth. Click on it and take note that the room can produce progression materials specifically for operators, skills, and weapons. |
| 2 |  The section shown above is where you'll assign Operators to work on a specific material. However, the work can drain the energy of Operators, and this will prompt a cooldown for them to work again. |
| 3 |  The section displayed is where you'll see the Growth Chamber status. You must first place special seeds to grow materials. To keep the cultivation going, extract more seeds to avoid pausing the progress. Click the slots to place the seeds. |
| 4 |  After placing the seeds in each slot, press Extract Seed, then click Extract. |
| 5 |  Select an Operator to increase the Growth Efficiency. |
| 6 |  Remember that you can upgrade your Growth Chamber by leveling up your Control Nexus and acquiring the necessary materials. |
Inform Xaihi of Your Results
Return to Xaihi once you've finished cultivating. She will inform you that it would be beneficial for you to keep rare materials in store to extract seeds from them. She also confirms that there are more unlockable cabins inside the Dijiang.
