In this chapter, we learn that cultivating through the use of spirit energy is a very powerful way to increase one's cultivation. In order to do this, one needs to enter the realm of spirit gathering, which is a higher realm than that of the body tempering realm. For example, if a cultivator enters the spirit sea realm, he will have a stronger spirit sea than a cultivator who enters the body-tempering realm. But if the cultivator does not enter the spirit-gathering realm, his spirit sea will not be strong enough to raise his cultivation. The reason for this is that the cultivator must be at the higher realm, and the higher he is, the more powerful his spirit energy will be. In other words, the higher his cultivation, the greater the danger he is in. This is why the young man, chu, is using a technique called the gathering revolutions, which involves condensing nine spirit sea into a single core. The core of this technique is to refine the spirit energy by repeatedly condensing the ninth spirit sea. After condensing, the core will offset the excess spirit energy of the spirit cores, and increase his cultivation at a faster rate. The young man , who is now called poison yan, thanks the master for his help in cultivating him. He tells the others to follow him wherever he goes, and warns them that if they don't follow him, they will be the first people to step into earth spirit in the city of xi feng.
