Well, the first, second and third meridians open meridians. If the meridians are close, you don't need to learn directly from the four meridians. If you don't open it, you can worship a brother from Sanjing to 30 years old, and then you can start. As for the three classics, you don't need to learn from 31 to 36. After all, you have got through the four classics, or the four classics are the main ones. The four classics are that the master took over the task at the beginning of 1-5. 6- 10 is sheepskin, and each layer needs four sheepskins. Then after learning 10, the system will give you a mailbox, open the mailbox, get the task, and complete it according to the task, and you will get the page of115. 16-22 is also sheepskin. When you learn to 22, the system will send another task email, open it and get the task. This email will eventually go to the villain Gu Xueshan to call a BOSS to play this. If the BOSS can't beat you, you can invite a good friend to help you fight. A good BOSS can cut off the return trip (as long as he can return to his sect). The master handed in the task and got 23-28 pages, and 29-37 pages were changed into sheepskins, just like five sheepskins on each layer. Finally 38-43, this is still an email sent by the system. The task of opening mail follows the task. This task is not difficult to play, but it takes time. The whole mission is like a story. At the end of the task, there is also a BOSS, but you can't invite friends to help, but this BOSS is not very powerful. After killing the BOSS, just find the door number and hand in the task. 44-49 is obtained from sheepskin and task. In Sannei, two 44 are merged into 45, and two 45 are merged into 46.
