Secret Techniques
Other than Qi Methods and Dou Techniques there are still some special Secret Techniques which exist on the Dou Qi continent. Their effects are usually something that will cause others to be envious. Some of them can even greatly raise one's strength. That night back at Wu Tan City, Xun Er used an advanced Secret Technique to enable herself to raise her strength to the Da Dou Shi class for a short period of time
Normally speaking, secret techniques were differentiated from good and bad. Something like stimulating the 'Heavenly Flame' to increase personal strength could be considered an excellent one while stimulating the blood to borrow its strength could be considered a lousy one. Moreover, some even more vicious secret techniques might even leave behind harm to the user that was difficult to remove.
However, no matter whether it was an excellent one or a lousy one, a secret technique was an extremely rare thing. It could be a decisive factor during critical moments. In more serious cases, it could determine the victor in a battle
Soul Skills
Soul Skills were just like Dou Techniques. If an expert who practiced Dou Qi did not have a Dou Technique, he would only be able to rely on the power of his Dou Qi to fight another. However, he would definitely be at a disadvantage if he fought with someone who possessed a Dou Technique. During ancient times, Soul Skills were similar to Dou Techniques and had been separated into Tian, Di, Xuan, and Huang class. Currently, Soul Skills were extremely rare.
Difference in the Qi Method
In the Dou Qi continent, the difference in the Qi Method was dependent on a few factors. The first was the accommodating capacity of the vortex holding Dou Qi. Consider two people of the same level, if one of them were to practice a Huang Class Qi Method while the other practiced a Xuan Class Qi Method, then the one practicing the Xuan Class Qi Method would definitely have a far greater battle endurance compared to the former.
The second factor was the difference in the Dou Qi quality. Under the assumption that both parties had the same level, if the one practicing the Xuan Class Qi Method had to use one unit of Dou Qi, then the one practicing Huang Class Qi Method would have to use ten times or even more than that amount of Dou Qi in order to obtain the same result as the former.
The third factor was the effectiveness in absorbing the natural energy and refining it into Dou Qi during training. This was similar to the previous point. If two people wanted to absorb the same amount of Dou Qi energy in the air, the one who practiced the Xuan Class Qi Method may only require ten minutes while the Huang Class Qi Method would require a hundred minutes…
The fourth factor was that in battle, the person practicing the Huang Class Qi Method would never be able to drive the Dou Qi as quickly or smoothly as the person practicing a Xuan Class Qi Method.
By summarizing the various reasons above, it clearly showed the reason for why countless of people on the Dou Qi continent would view a good Qi Method as the most important thing over any and all other things. The higher the class of the Qi Method one practices, the larger the amount of benefits that it would bring. Therefore, in order to obtain those high class Qi Methods, countless numbers of strong people would come wave after wave. Sometimes, they clearly knew that they were like moths jumping into the fire, yet they were still willing to be swallowed by the flame
Dou Techniques Ranking
1 Huang Class (Lowest): The most ordinary class of Dou Techniques.
2 Xuan Class: A High Xuan and Di class may merely have a one level distance, but the gap was just like that of the Heavens and the Earth. Most Xuan class Dou Techniques relied on the personal strength of the user to unleash its strength. However, a Di class Dou Technique was already able to rely on the natural energy to achieve an extermination-like destructive strength. One was a person and the other was the Heavens and Earth. There was basically no comparison between the two.
3 Di Class: A Dou Technique of this class was not only rare but it was also extremely difficult to practice. There is a frightening gap between that of the Xuan class Dou Techniques and the Di class Dou Techniques which could not be remedied.
4 Tian Class (Highest)
