Tribal conflict can't be played without money?

Playing games doesn't have to cost money. There are so many mobile games now, and the gameplay is different. Take the mobile game "Legend of Xuanyuan" that I am playing now. He has five occupations: warrior, mage, assassin, magic bow and pharmacist. This game is different from previous maps. The day and night time and weather system are introduced for the first time in the scene of falling moon slope, and players will be able to feel the weather changes such as dawn, sunny day, rainy day and dusk. Very dreamy feeling.
