Game Guide by Ragib Rawnak on Jan 27, 2026

Arknights: Endfield has a quest part called "Westward into the Valley" that you will get to at some point. Sending power to a bridge will let you cross it as part of this task. The Electric Nexus is where you should start.

You can use fast travel to get to the Core AIC area quickly. Once you are there, the objective to transmit power will begin in Arknights: Endfield.

Preparing the Equipment

You might notice that your power transmission only reaches 80m, which is not enough to hit the bridge. To fix this, you need to build Relay Tower units. Open your facility list to see what you have. If you need to make more, go to the construction menu under the placement tab.

You will need Origocrust for this, which you get by gathering Originium. Once the Relay Tower is ready in your inventory, hold Alt and click the Briefcase icon. Drag the tower into your hotbar so you can use it easily.

Powering the Bridge

Go to the power source and start the transmission. Walk as far as you can until you almost reach the 80m limit, then place a Relay Tower on the ground in Arknights: Endfield.

Connect the power line to this new tower. Repeat this step by starting a new transmission from the tower you just placed. Walk further toward the bridge and drop another Relay Tower when the line gets tight.

Link the power again and run the final line to the Electric Nexus. Once the connection is made, the bridge will turn on, and you can walk across.
