miHoYo has now released a new event called Genshin Impact A Thousand Questions with Paimon, which will reward players with Mora if they get it right.
This new event is a quiz that will reward players with Mora. There is a total of 5,000 Mora to be gained for every correct answer. To join this event though, they will have to pass the requirement of being Adventure Rank 10 first. This will end by November 21, 2021, which is advisable to hurry it up.
This is a good way to earn Mora for free and a very good amount of it. It is just before the launch of the upcoming version 2.3 update, which will introduce a brand-new event at Dragonspine and reruns of two 5-star characters. There will also be the introduction of two new Inazuma characters, Arataki Itto and Gorou.
