How to complete Automated Charging Genshin Impact's A Muddy Bizarre Adventure event

Automated Charging is the second part of the event. After completing Transportation Test, fast forward to the next in-game day to get the Event Quest called Spike Self-Circulation Report: Abstract. Speak to Hosseini in the Ad-Hoc Main Tunnel, then interact with the Pursina's Spike to begin. Make sure you have the Lumenstone Adjuvant equipped—at least level 2, but preferably level 3.

Your main goal is to ensure that the Pursina's Spike completely charges up within five minutes. You can view your charge progress on the lefthand panel of the screen. The Spike will charge as long as it's not being attacked by enemies. When it's being attacked, a cancel icon will appear above the Spike, indicating that charging has stopped.

Simply get rid of all enemies to allow the Pursina's Spike to continue charging. Dispelling nearby Oozing Concretions will make the Spike charge faster and keep enemies away. You can interact with various sources of Lumenlight, such as lamps and glowing orbs, to recharge your Lumenstone Adjuvant's Energy.

If you fail to complete the challenge, you can try again as many times as you like. After completing it, head to the event menu and claim your 80 Primogems—plus other rewards—from the Automated Charging section.
