Zhang Yi finally realized that the 【Collect Blueprints】 quest he received from Laura, whether hidden or normal, was actually a team quest!
When accepting the quest, it could be taken solo or with a group, but when executing the quest, it required 3-5 people, and everyone in the team needed to have the Collect Blueprints quest. Only then would equipment blueprints drop when hunting goblins at the Goblin Station on the quest map.
Additionally, based on the varying difficulty of the quest determined by contribution, most players needed to collect between 100-200 blueprints. Only Zhang Yi, who accepted the hidden quest, needed to collect 500 blueprints.
Of course, other players didn't have the exclusive privilege that Zhang Yi enjoyed: a tenfold increase in blueprint drop rate.
