In Genshin Impact, after meeting Bona at the Vucub Caquix Tower, players assist the Flower-Feather Clan adventurer in retrieving the Jade of Return. This involves overcoming Och-Kan, a menacing dragon, using Cocouik's "Super Awesomesauce Laser," which neutralizes Abyssal corruption. Successfully aiding Bona and defeating the dragon completes the "Vaulting the Wall of Morning Mist" quest, yielding valuable rewards, including Primogems.
To power Cocouik's laser, players must locate three Secret Source Scraps within Ashflow Street. These scraps replenish Cocouik's energy.
Secret Source Scrap Locations:
Scrap #1:
This scrap is found in a ruined tower southwest of the Vucub Caquix Tower. Defeat nearby enemies, then use Cocouik's Ring of Light to absorb the corrupted Phlogiston between the two purple Phlogiston cores in front of the tower. Collect the scrap.
Scrap #2:
Travel northeast to a tower with a Common Chest. Defeat enemies, position yourself between the two purple Phlogiston cores, absorb the corruption with the Ring of Light, and retrieve the scrap. After obtaining this scrap, the dragon will reappear and attack.
Scrap #3:
Climb the stairs northwest of the previous tower. Align the two corrupted Phlogiston cores within Cocouik's Ring of Light to acquire the final scrap.
With Cocouik's fully charged laser, target the Abyss-corrupted dragon's shield. Defeat the dragon in its lair (prepare a strong team!), complete the quest, and receive your 40 Primogems reward.
