Cai Yao looked at Li Sibai's appearance of wanting to speak and stopping, which was very interesting, and made her laugh "poof".

"Brother Xiaobai, you have a lot of questions, what do you want to know? Ask me to listen, I will tell you what I know. ”

Li Sibai was slightly suspicious, organized his thoughts again, and said:

"Cai Yao, how did I break through the fifth level of the Feng Chu Realm so quickly, I have never broken through the third level of the Feng Chu Realm after eight years of hard training before, I quickly broke through the fourth level of the Feng Chu Realm under your colorful light, and today under the green gas of this old tree spirit, I broke through the fifth level of the Feng Chu Realm again, what kind of spell is so powerful at this time, all this feels so real, am I dreaming? Hurry up and hit me to wake me up." Li Sibai smiled bitterly, and he didn't know whether he hoped this was a dream or not, and he was a little conflicted in his heart.

Cai Yao listened to Li Sibai's question, and she didn't speak, she was also organizing her voice and thoughts, thinking about where to talk to this stupid brother.

"Brother Xiaobai, I don't know if you feel it, there are two kinds of qi in your body?"

Li Sibai's eyes widened: "Yes, yes, yes, how do you know, when I was helped by your colorful auspicious light before, I felt my pure yang Xuantian Gong true qi, hot and warm, very comfortable;

Cai Yao nodded, and appreciated this brother a little more in her heart, although Li Sibai saved her by mistake before, and later she also saved Li Sibai, but after they got along all the way, Li Sibai not only impressed her with generosity, but also admired her tenacity even more. At this time, from Li Sibai's answer, it reflected his thoughtfulness, and Cai Yao silently gave Li Sibai a thumbs up in her heart.

"That's right, brother, your body is different from other people, there are red and white gases. ”

"The red one is my Xuantian Gong True Qi, and the white one is?" Thinking of the cold white airway, although there was a slight coolness, Li Sibai's whole person felt bad, and he was afraid that the answer to his guess would be confirmed by Cai Yao.

"Could it be..."Li Sibai didn't dare to say it anymore,

Cai Yao really didn't notice the change in Li Sibai, she said with certainty: "That's right, Brother Xiaobai, it's the fighting spirit that causes yin!!"

Li Sibai grew his mouth in surprise: "Ah!!"

Although he had already guessed this answer in his heart, it was just a guess, and he hoped that it was not true, but now that this guess has been affirmed by Cai Yao, it is basically a sure thing.

"How could it be ?!!"

"How can I have this yin-inducing fighting spirit in my body?!!"

"Cai Yao, are you joking with me??? don't tease me, I'm really timid. ”

Cai Yao didn't expect Li Sibai to react so much, but if you think about it carefully, this is normal, what normal person can still be calm when he knows that he has the Yin Fighting Qi cultivated by the Demon Clan in his body, then he is not a normal person.

"Brother, don't worry, I'll tell you carefully. ”

Li Sibai nodded, his mind was now confused, he had no clue at all, and he was hoping that someone would show him a clear path.

Cai Yao coughed a few times and said:

"Brother, let me ask you, your human race is actually turbidity, but turbidity can't be cultivated, right?"

Li Sibai nodded,

"Then when you cultivate immortals, do you absorb the pure qi in this natural everything, extract the pure qi and practice it into true qi through a Taoist method similar to Xuantian Gong, and then eliminate the turbid qi in the body, and so on and so forth, until the turbidity in the body is completely eliminated is the time to ascend to the immortal, right?"

Li Sibai said, "Yes!"

"Then let me ask you again, do you know how the demon clan cultivates?"

Li Sibai nodded: "I saw in that book of "Strange Things", the demon clan is actually ordinary birds and beasts, and their bodies are also turbid, through accidental coincidence, they have obtained the method of absorbing the pure qi of all natural things, but they cannot be transformed into true qi after absorbing the pure qi, but into fighting qi, this true qi and fighting qi are one yang and one yin, which are really two incompatible existences. ”

This time, Cai Yao was impressed by Li Sibai again, don't look at this brother's recklessness, but this knowledge reserve is really a lot, although the level of cultivation is not very high, but the principle is a little bit known.

"Yes, as my brother said, these two are one yang and one yin, and they are indeed irreconcilable, but brother, have you ever thought that they are also obtained from absorbing pure qi and cultivating them, what is the difference between this yang and yin?"

"This..."Li Sibai hesitated a little again, he originally wanted to say that of course it is different, this true qi is the pure yang true qi of my righteous path, how can I compare it with the yin and fighting qi of the crooked and evil way, but if I think about Cai Yao's question, if the two are not different in terms of cultivation, in addition to the different methods of cultivation, it is indeed not different, which is very embarrassing.

"It's... That one... It doesn't seem to be any different..."

Li Sibai's voice became smaller and smaller, so small that he could hardly hear it, but Cai Yao did hear it clearly, she smiled, and her smile was so bright.

"Brother, I really admire you for being able to figure out my little sister so quickly, it's true, except for the different cultivation methods and the different results, the others are the same, they are all based on the pure qi between heaven and earth, and they output different sources, but they are all the same, your cultivation of true qi is to cultivate immortals, and my cultivation of fighting qi is to cultivate demons and demons, and the pursuit is indeed immortal. ”

Li Sibai grew up in this Jade Void Peak Xuantian Sword Sect since he was a child, and what he heard since he was a child is that good and evil are not separated, evil does not suppress good, and the words of eradicating demons and demons are always felt that the teachings of the master in the past are naturally extremely sacred, and they should be born like this, and they will never be wrong, but now after listening to Cai Yao's words, it seems that there is some truth in it, and he can't make a choice, he is really confused.

"But Cai Yao, where did the fighting spirit on my body come from, do you know?"

"I don't know this, brother, I'll ask this old tree spirit later, he has outlived me, he may know. Cai Yao smiled.

Li Sibai had some doubts again, and said: "What's wrong with him, why does he seem to be asleep? Could it be that I was tired of upgrading just now?"

"Hehe, brother, you underestimate him too much..."
