How to unlock Lingbao on a Chinese Odyssey 2

First of all, the skill bar can be opened by thunder tactics, which is similar to opening the summoning skill bar.

2. Secondly, you can also use the item "Lingbao Tianwei Drink" to open it, which may fail! The number of Lingbao Tianwei seals required to open the skill bar is also different.

3. In the end, the more you go to the back, the more you need it. If you win the battle, you will have a chance to improve the quality of Lingbao. You can also open it through the item "Lingbao Zhu Tianyin". The higher the opening quality, the more you need. These are the skills to open the skill box in A Chinese Odyssey 2.
