The power of combo is determined by the equipment, internal skill level and the number of layers of combo practice. Only the higher the internal skill, the more combo you practice.

There are four tricks in combo, and you can practice up to five tricks for each trick. The main number 1-4 combo trick requires 5-8 first-level gold needles for the first combo, corresponding second-level gold needles for the second layer, and third-level gold needles for the third layer, and so on. As long as your internal skill is high enough and you have enough gold needles, you can increase your strength. Heroes can be obtained by accumulating meridian experience and playing a green name on the premise of adequate internal skill level. The more you practice, the more meridian experience you need. If you have enough, you can click on the practice pulse and practice combo. Settings: Open the character status bar, internal skill, combo, click the first combo+10%, select the name of the first combo, click the second combo+15%, the third combo, and so on (provided that you have already hit the combo), so that your main number can be CTRL+D to the first combo.
