Arknights Endfield – All Wuling City Protocol Datalogger Locations
Wuling City Protocol Datalogger #1

You can find this Protocol Datalogger near the Technological Production Office. Locate the SOS crates in the middle of the rice paddy fields. Cross the rice fields until you see a house with some domestic birds. You can easily spot the bright yellow inflatable tube balloon once you reach the farms.
Wuling City Protocol Datalogger #2

The second Protocol Datalogger in Wuling City is located in the Residential District. The Datalogger is placed on the corner of the street that connects the Residential Area and the Bureau of Swordmancers.
Wuling City Protocol Datalogger #3

The third Protocol Datalogger in Wuling City is on the roof of the Tianshi Bureau Academy. Teleport to the academy and start going up the stairs until you reach the upper terrace. Once there, you should be able to see a glass bridge beneath a waterfall. Cross that bridge and the subsequent balcony until you see the yellow balloon.
Wuling City Protocol Dataloggers #4 & 5

The fourth and fifth Protocol Dataloggers in Wuling City are located in the Fangxing Avenue area. They are placed right next to each other, so you can easily get them done in a single run. You can find them on both sides of the entrance of the Eureka Tea House.
Wuling City Protocol Datalogger #6

You can find the sixth Protocol Datalogger at the Monitoring Center. This center is a separate island, situated in the northeast direction of the mainland Wuling City. Travel inside the Monitoring Center and go to the balcony on the far east side of the base. The Datalogger is placed on the balcony overlooking the valley.
Wuling City Protocol Datalogger #7

The seventh Protocol Datalogger in the Wuling City area is located in the Field Logistics Depot. This base is situated on an island that falls between Wuling City and Jingyu Valley. Take the stairscase on the left side when you teleport to the Field Logistics Depot. Keep going straight ahead and cross five staircases until you see the yellow balloon tube.
Wuling City Protocol Datalogger #8

The final Protocol Datalogger in Wuling City is situated near the Institute of Materials Science. Teleport to the Institute and start going south. Cross the grounds and sports courts until you come across the yellow inflatable tube-man indicating the Datalogger.
FAQs
Why can’t I find any Dataloggers in Wuling City?
You need to complete Chapter 1 and speak with NPC Andre if you want to start connecting all Dataloggers in Wuling City. However, some areas in the city are gated behind a further main story, so I highly recommend completing Chapter 2 and then starting your quest to finish all 8 Dataloggers.
Are Dataloggers hidden like Crates or Aurylene?
No. Unlike Crates or Aurylene, you can easily spot Protocol Dataloggers, because they have a tall yellow balloon ‘man’ on top of the machine. Furthermore, Protocol Dataloggers will be tagged automatically in your map when you are in the general vicinity. Ideally, you would have unlocked most of them on your in-game mini-map when you complete main story beats in Wuling City.
What is the major reward for collecting these Protocol Dataloggers?
You get AIC Index data, which is a highly sought-after currency. It lets you unlock advanced factory technologies as well as Blueprints in your Tech Tree. I highly recommend you get all eight of these done, especially if you want to get your hands on a unique blueprint like the HE Grenade Tower.
