Go Back to Yasumoto’s House & Give Naku Weed
After completing the ‘Treatment on the Island’ world quest, go to Yasumoto’s house and place 12 Naku Weed in the bamboo basket in front of his house. Return back to the same place the next day (Real Life Day) and you will find an exquisite chest. Open the chest and then place 12 Naku weeds in the bamboo basket again and repeat the process for two more days. The third time you come back to Yasumoto’s house, you won’t find any treasure chest in front of the house and the Naku weeds will still be there in the basket. Interact with the basket and the dialogue will hint you to use elemental sight to track the owner. Use the elemental sight and it will lead you to three Pharmacist’s Notebooks.
