Treat the injured merchant
Travel to Sorrowfield Village in Kaifeng and investigate the injured merchant near its southern edge. Use Wind Sense to identify the treatment interaction, help him, then follow the traces into the deserted village.
The quest is also called Twelve Years of Grudges or The Twelve-Year Grudge. Track the active legacy entry so an alternate title does not send you searching for another story.
Follow the shadow into the courtyard
Inspect the fungal traces and pursue the black shadow. When the closed entrance stops the ground route, climb over to the courtyard and prepare for the hounds. Clear the group, then speak to the village chief at the shrine.
Leave when directed, return to eavesdrop and wait for the night investigation objective. Use the clock rather than standing beside an inactive daytime marker.
Steal the Ancestral Hall Key
At night, reach the rooftop observation point and listen to the meeting below. Follow the chief’s movement and use Celestial Seize on the Ancestral Hall Key from the indicated viewing position.
The objective is theft without being caught. Attacking the NPC is not an alternative key interaction. Once the item is obtained, return to the shrine and unlock its inner gate.
Enter the memory through the tablet
Inspect the suspicious tablets, especially the one wrapped in mycelium. The transition takes you into the past around Zheng Manor. Untie the young boy, follow him and help him when he falls. Examine the distant street and firelight when the objective asks you to survey the scene.
Continue by the prompted traversal route toward the Town Academy, activating the checkpoints you pass. If the route appears to end at a wall or burning street, look upward for the next traversal prompt before backtracking.
Clear He Yuezhi’s support first
At the academy, the boss is accompanied by other enemies. Deal with the ranged threats and remaining henchmen before settling into the main duel. Keeping every attacker alive makes it harder to read the polearm sequence.
Use short attacks after completed swings and save committed skills for a real opening. You are preparing for another boss afterward, so avoid spending all healing simply to finish the first courtyard faster.
Continue to Shen Yiren
Follow the route to Zheng’s Main Residence and resolve the henchman stage. Shen Yiren combines spear pressure with ranged bow attacks. Reassess your spacing when he changes weapons; an opening against the spear is not automatically safe against the next ranged sequence.
Defend the committed attacks and use their recovery to make progress. If you lose track of the fight, reduce your own effects and focus on recognising the next weapon action before rebuilding a long rotation.
Finish the story after the fight
Check on young Zheng E, continue the final transition and speak to the tomb keeper about what happened. The Toxic Arrow recipe is a completion reward, so defeating the first boss alone does not finish the unlock.
Afterward, inspect the recipe in the crafting interface and its required materials. Learning the recipe and having crafted ammunition are separate states; select the actual arrow type before expecting its effect from a bow shot.
