Still in the first chapter of Emperor Freezia of Dragon Ball Z Kakarot, go see Oolong near the Capsule Corp, this one has a secondary story for you! Indeed, the poor little piggy thought he saw his buddy's ghost walking around town. It's up to you to solve this mystery.
Yamcha is alive
Another simple sub quest: go to each red dot, until a battle against RR units is triggered. If you don't have a little experience as a farmer, you might encounter a little resistance from them, but then really a bit of a shudder. As usual, against large groups, first smash the support units capable of healing their colleagues, then finish with the armed units. After this fight, the masks fall off and you can then pocket the reward, no soul emblem this time.
