# NFT Card & Earn

You can buy an item pack or mix NFT Cards to upgrade to higher level card. If you hold a regional collection NFT Card, you can build up a team to enter a regional occupation battle that seize the region. Collect a regional NFT Card and enter the battle. If you hold the NFT Card, daily reward (rental income) is given. Gain the rental income that comes with NFT Card holding.
