How to resist evil

Talk to General Dilios at Keucereus Alliance Base . You must prove your strength to him. The first step is you must demonstrate your ability to fly, you must click 2 times if you have already completed the flying transformation quest, otherwise he sends you to do the Good Day to Fly quest to receive a certificate from Lekon that you have the flying transformation.
After General Dilios is convinced of the authenticity of the document, he sends it to Special Product Broker Kutran.
Kutran stands on the other side of the Lekon fountain. He will talk about special items that can be found in Seed strongholds: Imperfect Soulstones in Seed of Infinity and Dragon Rider's Totems in Seed of Destruction . For every 5 Imperfect Soulstones he will give 1 Purified Soulstone, for every 5 Dragon Rider's Totems you will receive 1 Dragon Rider's Talisman. Read carefully what Kutran says so that you can better plan what items to collect next.
You can only spend a certain amount of time in strongholds, so you have to beat everyone. When we have filled up the items within the allotted time, we return to Kutran and exchange items as stated in the previous paragraph.
Purified Soulstone and Dragon Rider's Talisman are exchanged for materials and recipes for Ikarus weapons, as well as improvements for S80 armor, lvl 81 Spellbooks - to exchange for all these things you will need a lot of items.
