To start this quest go to the Events page and then into Event Details, Meteoric Wave and then the quest “Unlimited Opportunity”. This will add it to your Quest log, click Navigate and your objective will tell you to talk to Ivanovich. Ivanovich can be found just east of the Liyue Teleport Waypoint. After speaking to him he will tell you that he wants you to bring him back some meteorite shards, after some time dissuading him not to do that he will ask you to bring him back some flowers.
The plants can be found south of Liyue Harbor, as you approach the flowers you’ll be attacked by a Pyro Whopperflower, use Cryo and Electro to make short work of it and then pick up the three Sweet Flowers. Head back to Ivanovich in Liyue.
