The clusters of palace lamps on the stout Optimus Prime in the library were still as bright as ever, and the night was already deep, and Rue Hua sat on the ground, yawning as she flipped through the scrolls, and it didn't take long for her to fall asleep. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 Feng Jiu Yuan glanced at her, shook his head with a smile, yawned, and continued to flip through the next scroll.

When it was almost dawn, she finally found a pair of somewhat tattered scrolls in the most inconspicuous corner in the lower left corner, and after opening them, her originally sleepy eyes instantly became energetic, and she muttered: "The Ten Ancient Demon Swords: Buddha Devouring Sword, Heart Sword, Biyan Sword, Burning Sky Sword, Gu Spirit Sword, ......"

Although the scroll is worn, the pattern of each sword drawn on it is very clear, in which, the basic characteristics of each sword, the destructiveness and weakness of the sword spirit are depicted in great detail, and the owner of each sword is also marked on it, only the pattern of the Buddha Devouring Sword is blank.

"Could it be that the Buddha Devouring Sword has really disappeared? How could a devastating magic sword with no weakness at all and that is feared by gods and demons disappear all at once?" she sat down on the ground against the bookshelf in disappointment, and said in her heart: Even if you disappear, I will definitely find you out if you go to heaven and earth!

Yunhua next to her head suddenly tilted to the side, and was woken up by her own fright, and saw Feng Jiu Kite sitting on the side in a daze, rubbed her eyes and asked, "Nine Kites, have you found it?"

Feng Jiu Kite nodded, "Found it." She handed the scroll to Ruhua, who took it and browsed it for a while, and asked, "Nine Kites, do you really want to learn about the Buddha Devouring Sword just out of curiosity?"

I didn't expect Yunhua to look silly and innocent usually, but in fact, she is quite delicate and sensitive to some things.

"I'll tell you the truth, I want to find the Buddha Devouring Sword and save a friend of mine. ”

Rue Hua looked at her curiously, "What's wrong with him? Does it have to be the Buddha Devouring Sword to save him?"

"I don't know what to tell you. Feng Jiu Kite stood up and put the scroll back in place, "You can stay with me until dawn, Yunhua, thank you for your hard work! Let's go, it's almost time for morning class!"

"Hmm!" Yunhua took Feng Jiu Kite's hand and stood up, looked at Feng Jiu Kite's slightly worried look and said: "Nine Kites, you have to remember that no matter when, my Yunhua is the most supportive friend of you, no matter what difficulties you encounter, you have to tell me, don't keep it in your heart, I hope I can help you." ”

Feng Jiu Yuan smiled, took her hand and walked out, "Okay, I know!"

On this day, Feng Jiu Kite stood upside down under the weaving cloud tree in front of Danzong's room and silently memorized the Danshu theory on the ground, because he had not slept all night, he couldn't help but doze off when he looked at it. However, she is so powerful that she will not fall down when she dozes off, and she still maintains that upside-down position, but her eyes have been closed, and Harazi is dripping down.

Danzong walked out of the room, stood at the door of the room and looked at her for a long time, his eyes fell on the scroll that was wet with her saliva, raised his eyebrows, reached out and took the scroll back, a silver whip appeared in his other hand, and he walked over and slapped her ass!

"Ahh

"What's the matter? You're still not happy to smoke you?"

Hearing this, Feng Jiu Yuan muttered, "Isn't this nonsense?

"What did you say?"

"Didn't say anything!"

Danzong looked at her carefully, and pretended to be stern: "You still dare to talk back to the teacher! Have you memorized all the Danshu theories on the scroll?"

"Of course, I think Miss Ben was the champion of intercollegiate recitation in college back then!" Feng Jiu Kite raised her head.

Although he didn't know what "university" was and what "inter-school recitation champion" was, Danzong could roughly hear what she meant by saying that she was very powerful, so he said: "That's good, I'll test you as a teacher!"

Feng Jiu Kite hooked his lips and smiled, "Let the horse come!"

Seeing that she looked very confident, Danzong put his hands behind his back and asked, "I taught you before, alchemy is not only to master pharmacology, but also to understand the rationality, qi, and mathematics that are closely related to it, so what is rationality?"

Feng Jiu Kite recalled for a moment and replied: "The so-called principle refers to the laws and laws of nature, which include the five elements of yin and yang, the sun and the twenty-eight constellations, and the laws of day and night, spring, summer, autumn and winter, birth, old age, sickness and death...... It conforms to all things and restricts all things. ”

"What does that mean?"

"Counting," she thought for a moment, "in layman's terms, counts refer to the existence and manifestation ......of celestial bodies in the universe. The reason why the stars in the sky, no matter how time and space alternate, can coexist peacefully is because each of them is in its own normal position, each has its orbit and laws, and they have different distributions to bring various interactions into balance. Not only the stars in the sky, but also all kinds of natural things on the earth can reflect the balance of numbers, and this balance is also in motion due to the constant change of yin and yang. The number of heaven and earth can derive the number of all things, so it affects the changes in the natural state of affairs and the trend of the growth of all things. ”

Danzong nodded happily, "Then why are you angry?"

"Qi refers to the breath of nature. Following the 'Principle' in the balance of a certain 'number', Qi energy promotes the formation of the universe and releases a mutual influence as all the energies that exist in the life process. Combining reason, qi, and numbers to refine the elixir, it can absorb and merge the aura of heaven and earth, and give a natural spirituality to the refined elixir, and the quality of the elixir is naturally the best of the best. ”

"Hmm!" Dan Zong said, "I remember well! However, the best places for reason, qi, and numbers are difficult to find and dangerous, and many Dan masters will not take this risk if they have to refine the Heavenly Tribulation Divine Pill." ”

The Heavenly Tribulation God Dan Feng Jiu Kite has seen it on the scroll given to her by the medicine spirit, such as the Immortal Pill, the Nirvana Pill, the Bodhi Pill, etc., once practiced, they all have to go through the Dan Tribulation, but she has never seen it, and she doesn't know what the Li Dan Tribulation will be like.

Just thinking about it, there were footsteps approaching step by step, and turning his head sideways, it was Senior Brother Ling Chang.

Dan Zong said: "Get up!"

Feng Jiu Yuan stood up, and after Ling Chang saluted towards Danzong, he saluted Ling Chang, called Senior Brother, looked at the medicine basket on his back and asked, "Senior Brother, are you going to collect medicine?"

Ling Chang smiled, "Exactly, I want Wuhua Mountain, come and talk to Master before going out." ”

Danzong nodded, "Go ahead!"

Seeing that Ling Chang turned around and was about to leave, Feng Jiu Yuan hurriedly stopped, "Senior brother, wait!"

Immediately afterward, she said to Danzong: "Master, you see that I have memorized the Danfang theory for almost two months, why don't you let me go out with my senior brother to collect medicine? By the way, I can also follow my senior brother to identify some more herbs!"
