The universal qigong book of "Hot-Blooded Jianghu and Ascension to Heaven"
The upper limit of the Sixth Transformation Heaven Ascension Kung Fu that can be learned is 6.
1 for this profession and 5 for other professions.
The general Qigong books you are referring to are the five ones besides this profession.
Each profession needs to learn different qigongs. Some qigongs do not need to be learned, such as those that add internal strength and avoidance.
The general qigong that needs to be learned is mainly to increase attack, defense and blood, such as: Splitting Huashan with force, Changhong penetrating the sun, Zhengben Peiyuan.
The specific type of Qigong you want to learn should be based on your professional needs.
Personal suggestion:
You definitely need to learn the professional Qigong in Ascension Skills, followed by the ability to increase attack, because the rate of increasing attack is very high. That is, the power of ascending to heaven splits Mount Hua, and the ascending rainbow penetrates the sun. It is not recommended to waste Qigong on the Ascension Golden Bell Qi (increases defense) and the Ascension Original Accompanying Element (increases blood), because it only takes 20 points to add 20 defense and 208 points of blood, which is the same as the increase rate of Qigong without Ascension. On the contrary, the rate of increase in Ascension Power to Split Huashan is greatly increased. 20 points can increase the attack by several hundred points.
