Troublesome Work is a series of quests in Genshin Impact given by Lisa.
Your task is to help her retrieve books that are due in the library.
Here’s a walkthrough of Troublesome Work in Genshin Impact.
To begin the quest, meet Lisa at the library in Mondstadt.
She’s waiting at the upper floor of the library.
Troublesome Work
The first sub-quest is also called Troublesome Work. You have to meet Marjorie first. She runs the souvenir shop in Mondstadt.
In this quest, you have multiple choices for Lisa. However, the choices may not affect your rewards, but I’m not totally sure.
Here, you have to choose a gift for Lisa. The best answer should be Ragged Old Scroll.
Next, talk to Sara who is the waitress nearby.
Ask her about Lisa’s taste in food and she’ll tell you that Lisa likes veggies.
Next, talk to Lisa and choose Radish Veggie Soup.
Lastly, go to Donna who is at the flora shop.
Here, the best option for Lisa is Cecelia. Pick the flower yourself and then talk to her again.
Picking the right options will make Lisa happy, but I doubt there’s anything more to that than the dialogue, at least not for now.
Donna will tell you that the book she borrowed has been stolen.
Lost Book
The next sub-quest is Lost Book.
Use elemental sight to find the purple energy on the ground. Investigate it.
Next, go out of Mondstadt and right after the bridge, use elemental sight to see the purple energy.
Continue following the yellow marked area on the map which will lead you above the hill, near a treasure chest. Use elemental sight again to find the energy.
Once you’re done, go to the next yellow area to find the next clue.
Now, you have to follow the elemental energy. Use elemental sight to see where the energy flows and follow it all the way.
You will be led to a secret entrance made by an Abyss Mage.
Enter the Abyss Mage Stronghold when you’re ready.
At the first part, you need to glide using the wind current.
While gliding, watch out for the wind currents going sideways. They can push you away.
Also, don’t get hit by the thread that’s either moving up and down, or moving left and right.
Keep gliding until you reach the platform.
In this area, the door in front is locked. Go towards the right side and you’ll see sensors. Use an electro attack to activate the sensors, which will then open the door.
In the next area, zap the sensors as well. The electro current will then flow and open the door. Zap the sensors on the left (not the one with the arrow pointing to it).
In the next area, do the same thing and zap the sensors to open the door.
You will reach a room with a console in the middle. Go near and slimes will appear.
Get rid of the slimes first and the console will be unlocked.
Use the console to start the wind current.
Fly up the wind current and look for the next path.
Kill the slimes inside the room. Lisa is a good choice for this room.
Once you’re done with the slimes, start the console to do a timed challenge.
More slimes will appear. This time, you only have 30 seconds. Use Lisa to electrocute all of them at the same time.
You will gain extra seconds when each slime dies, so you may want to target the small ones first.
After the challenge, use the console again and Abyss Mage Emery will show up.
You can either use a pyro or an electro character to kill him quickly since the Mage is cryo based.
After defeating the Abyss Mage, use the second console to open a path underground.
Jump down the hole and open the treasure chest to find the missing book.
Return to Lisa at the library in Mondstadt.
After the cutscene, pick up the Teyvat Travel Guide from the bookshelf nearby.
The quest ends here.
