Song Jingtian saw Kong Rui's doubts at a glance, and said: "I just said that there is no ordinary exercise suitable for you, I have a special exercise here, but it is just right for you." ”

"What exercises?" Kong Rui was even more strange.

"Yin and Yang Jue. Song Jingtian's expression was very serious.

Seeing that he was serious, Kong Rui didn't dare to ask more, so he waited for him to continue.

"With your twofold spiritual root talent, at most, you can only practice ice and fire skills or Xuansu Gong and the like, if you want to practice this kind of exercise, you are destined to be stuck in the middle and late stages of the spirit disciple in this life, and it will be difficult to take a step forward; Song Jingtian continued.

"Why is such a good exercise a special exercise and not generalized?" Kong Rui was suspicious in his heart, so he hurriedly asked.

Song Jingtian laughed and said, "How can anyone practice this kind of mystical exercises if they want to? Moreover, this Seven Profound Spiritual Wisdom Great Array was created by the ancestor back then, and there was never a mistake in selecting exercises for his disciples. Since it was Master Zu who chose you to practice this exercise, there must be his old man's meaning, do you practice it or not?"

Seeing that he was honest, Kong Rui moved out of the ancestral master again, so he had to nod and agree.

Song Jingtian saw that he agreed, so he said: "The only drawback of practicing this exercise is that you need to comprehend it yourself, and there is no one else in the same sect who is practicing yin and yang. Kong Rui's heart beat a drum, and he hurriedly asked: "If I don't understand, who should I ask for advice?" Song Jingtian said: "If you have a question about the scriptures, you can come to me directly, and the rest depends on your own understanding." ”

Kong Rui regretted it in his heart, so he thought about it carefully and asked, "If I practice this kind of exercise alone, if there is any competition, won't people see through it at a glance?"

Song Jingtian seemed to have been prepared, and said, "I naturally know this, so I will also give you this ice and fire skill scripture as a cover." The first stage of the Yin and Yang Technique is extremely similar to the Ice and Fire Technique, you can just see for yourself and understand it, but it is not for you to cultivate it. Moreover, there are at least twenty percent of the disciples in the sect who are practicing ice and fire skills, and if there is something you don't understand, you also have someone to ask. When Kong Rui heard this, he had no choice but to agree.

After making a vow not to pass it on, Song Jingtian rubbed the Yin Yang Recipe and the Ice and Fire Gong Sutra on a jade slip, and let Kong Rui drop a drop of essence blood on a jade slip to refine it, and then handed it to Kong Rui, and taught Kong Rui how to open the jade slip with the art of blood forbidden. Finally, he instructed: "When you mention it to others, you can only say that you have practiced ice and fire skills, and you must not mention half a word of Yin and Yang Formula; if you reveal the slightest rumor about Yin Yang Formula or its contents, I will not spare you." ”

Kong Rui only felt a huge pressure coming, and he couldn't help but shiver, and said that he didn't dare.

Song Jingtian saw that Kong Ruicheng was terrified, and with a wave of the sleeves of his robe, he sent him out.

The deacon disciple saw that Kong Rui had only come out in the past half a day, and he was very strange in his heart, so he asked, "Senior brother has come out, what exercises did you choose?"

"Ice and fire. Kong Rui replied angrily.

The disciple was curious, but seeing that Kong Rui's face was not good, he thought that this kid must have been trained by Master Song. He took off the token and sent him away, but he wondered in his heart, why did this kid only have an ice and fire skill for so long?

Kong Rui saw that it was still early, and the Hidden Scripture Pavilion was very close to the Shuren Hall, so he ran to the Shuren Hall and waited for Su Yun to chat for a while, but he never dared to mention the matter of the Yin and Yang Jue.

In an ordinary room in a secret realm of Wuxuanzong, Song Jingtian respectfully said to a white-robed old man who was sitting cross-legged with his eyes closed: "Uncle Qiyu, that yin and yang trick has appeared. ”

The white-robed old man's eyes widened, and a breathtaking light flashed in his eyes, and he said, "What is the specific situation?"

"This child's name is Kong Rui, he is a disciple of a two-fold spiritual root, it took three and a half years to practice qi Chenggang, mainly cultivating swords, and now he is worshipping under the Lingji Mountain lineage. "Song Jingtian is also honest.

The old man was noncommittal, but just said: "The sword is also the weapon of the king." He waved his hand and sent Song Jingtian away.

Song Jingtian was confused, but he didn't dare to ask anything, so he returned to the Scripture Pavilion.

As soon as Kong Rui returned to his room, he immediately took out the jade slip to check the exercises and scriptures inside, and sure enough, he saw that a large part of the first half of the Yin Yang Technique was extremely similar to the Ice and Fire Technique, and even the signs after practice were similar, and they were all divided into three stages, corresponding to the beginning, middle, and late stages of the spiritual disciple period, and each stage was divided into nine layers, and there were also different signs of exercises corresponding to different cultivation levels. Kong Rui saw that it was indeed as Song Jingtian said, and thought to himself that he would practice this yin and yang technique as ice and fire.

Then, Kong Rui began to carefully figure out the meaning of the scriptures. After looking at it a little more, he felt very strange in his heart, when he reached the back few layers of the first stage, the Ice and Fire Gong either refined Yin or Yang, and basically went in a unilateral direction, but this Yin and Yang trick was refining Yang for a period of time, refining Yin for a period of time, and it seemed to be more balanced.

Kong Rui had never had any concept of this kind of practice, but if he were to show it to any experienced spiritual disciple, he would definitely not dare to practice it like this, practicing yin and yang together, it would damage the meridians at least and endanger his life at worst; he didn't know anything about it, but he thought that he could have a better balance, and he didn't dare to ask someone, so he could only think so self-righteously.

The exercises in the early stage of the Yin-Yang Jue were not very complicated, and Kong Rui quickly mastered the key to it, and began to practice it after dinner.

The next day, Kong Rui found Senior Brother Ji as promised, and Ji Feng's words made Kong Rui bitter. It turned out that Sima He decided that Kong Rui was a malleable material, so he asked Ji Feng to arrange a strict training plan for Kong Rui, including the cultivation of his own mana, the practice of swordsmanship, and the control of offensive and defensive puppets.

As soon as Kong Rui heard this arrangement, he didn't even have time to see Sister Yun, but he didn't dare to say no, so he could only stiffen up, and Sima He also personally asked him to carry a second-order scorpion puppet and a huge second-order human-bear puppet with him to practice diligently, and these two puppets were one of the most difficult to practice one attack and one defense two puppets in Lingji Mountain.

However, when a spiritual mountain-like disciple trains in the sect, he only has one puppet that can be carried with him, and only when he goes out and has a task can he have more puppets available, of course, he can go to the warehouse to replace other puppets when he practices on weekdays. This is also the reason why Lingji Mountain does not have many resources, and it is impossible for everyone to be equipped with more puppets. Although Ji Feng was a little strange in his heart, he never doubted Sima He's decision, so he carried it out.

And so it went for three months. Su Yun came to Lingji Mountain a few times, but she never saw Kong Rui, so she inquired on the side, and learned that he was firmly watched by Senior Brother Ji and cultivated hard, but she felt very relieved in her heart, she hoped that Kong Rui could get the attention of the sect, and she didn't care about short-term encounters, anyway, there were still three months to go, and she came to this Lingji Mountain.

Kong Rui has been depressed these days, it's not that his training is too hard, as far as his ability to endure hardships is concerned, there is nothing in these trainings, it's just that his mana cultivation is too slow. He inquired with Senior Brother Ji and heard that even if it was a twofold spiritual root, the first layer of Ice and Fire Gong could be practiced in three months at most, but Kong Rui still felt far away after three months.

That night, Kong Rui lay on the bed and tried to think about what the problem was and how he could use his strengths to make up for it as soon as possible. He thought of this yin and yang recipe to refine yang first, and then refine yin, he should be able to use one heart and two uses to refine yin and yang at the same time, and he can also divide his mind to do something else.

Thinking of this, Kong Rui immediately began to experiment, and at the same time began to practice yin and yang, but he didn't find anything wrong, it seemed that there was still some effect, he couldn't help but be a little secretly proud, what kind of exercises can get twice the result with half the effort? It seems that only the method that suits him is twice the result with half the effort.

In fact, this yin and yang technique is an extremely exquisite exercise summed up by the ancient powerful people who penetrated the reincarnation of all things. Yang is life, yin is extinguished, even in the primary exercises, this tenet has always been followed, and in the transformation of yin and yang, mana can also be purified, which is indeed of great benefit to future advancement. The shortcomings in the exercises are not recorded in the scriptures, but some of the experiences of the predecessors who have cultivated the Yin and Yang Recipe of various generations have been handed down, and they are all in the hands of the Supreme Elder, who has cultivated the highest level in the sect.
