Wuthering Waves: Touch-and-Go Mission Guide

First, head west to the location near Husi Cliff.

You’ll encounter an exile named Yongli, who has collected a bunch of explosive barrels. Simply blow them up.
After the explosion, continue talking to Yongli to pick up the quest.

Choose to help him collect, and he will inform you that there are many explosive barrels at the Exile Camp for you to retrieve.
Once at the camp, you’ll find two circles of light and a corner full of crates.

One of the circles of light informs you that many of the explosive packs have been taken by someone named Afeng. Follow the guide to find Afeng.

After talking to Afeng, you’ll learn that he wants to use these materials for cooking.
Jinsebei: Obtainable at the beach.
Xiangsu: Obtainable at the Shifang Pharmacy.
Yinhuitui: Obtainable at the Forest of Darkness or Jincheng.
After delivering the items, take the excess explosives behind Afeng and bring them to Yongli.
Then, get ready to blow up the rock wall.

Take out your ranged weapon and shoot at the explosive pack to open the rock wall. At this point, a group of exile leaders will appear to contest the treasure with you.

Defeat them and then talk to Yongli.
Once the conversation is over, the mission ends.
