How to activate the legend of martial arts

At present, only the picture books of Qixia Town and Wubagang have been published. The activation of picture books requires cards, which must be used in the order of copper card, silver card, gold card and diamond card. After reaching a certain number, you can activate the cards. In Bai Zhantang, you can exchange colored shells for card packages. There are 6 cards in a card package, which can also be purchased from players, because the cards in the card package are all random color shells. At present, they are all obtained through tasks. Players above level 90 can get the task "Glory of Labor" at Beijing Shentang, and after completion, they can get 30 colored shells (it takes 300J to complete the whole task). Now the task of the gossip theater will also send colored shells.
