The Book of Changes actually refers not to one book, but to three books. The Xia Dynasty's "Lianshan", the Shang Dynasty's "Guizang" and the Zhou Dynasty's "Zhou Yi", these three scriptures and hexagrams are collectively known as the Book of Changes, which is the so-called "Three Changes". But because the two copies of "Lianshan" and "Returning to Tibet" have been lost, only "Zhou Yi" has been handed down.

And now, what we call the Book of Changes is basically talking about "Zhou Yi".

"Zhou Yi" is said to have been written by King Jichang of Zhou Wen, and the content includes two parts: "Sutra" and "Biography". The "Sutra" is mainly sixty-four hexagrams and three hundred and eighty-four hexagrams, and the hexagrams and hexagrams have their own explanations (hexagrams, hexagrams) for divination. "Zhou Yi" does not put forward the concepts of yin and yang and tai chi, and the one that talks about yin and yang and tai chi is the "Yi Chuan" influenced by Taoism and yin and yang. The Biography contains seven kinds of texts that explain hexagrams and epigrams, with a total of 10 articles, collectively known as the Ten Wings. This is the complete "Zhou Yi".

"Zhou Yi" mainly has eight trigrams, which are Qian, Kun, Zhen, Gen, Li, Kan, Redemption, and Xun.

Then why do you say 8864 hexagrams? Then you have to mention "爻", which is pronounced yao two sounds, forming the length of each hexagram in the eight trigrams. "—" for the yang, "--" for the yin. Every three lines are combined into a hexagram, and eight trigrams can be obtained; If the two hexagrams (six hexagrams) are weighted together, there are sixty-four hexagrams, which are called other hexagrams. 爻 means staggered and changing. This is where the 8864 hexagrams come from.

Each of the sixty-four hexagrams has its names, such as the Qian, Kun, Zhūn, Meng, Xu, and Lawsuit...... I won't go into too much detail here.

Each of the 64 hexagrams has its corresponding orientation, so there are different footwork. If you go from the beginning to the end of the sixty-four hexagrams, it is exactly a circle.

Therefore, the key to mastering Feng Ling's legs is to take different footwork according to different enemy situations. This is the footwork, the power of Feng Ling's legs, footwork is only one of them, and the other is the use of the qi of heaven and earth.

The qi of heaven and earth is the premise of whether Feng Ling's legs can be successfully exerted, fly into the sky, and move quickly.

It is obviously much more difficult to control the qi of heaven and earth with your legs than it is to control the qi of heaven and earth with your hands. And even if it flies, it is difficult to grasp the balance, and it can even be said that this kind of flight cannot be compared to even Edgeworth's flight.

However, Sour Xiucai did not let Tong Yan directly master the ability to fly in the sky, he could walk on the ground like flying, with the speed of the qi of heaven and earth and the subtlety of the eighty-eighty-sixty-four hexagrams, it was as difficult to chase as the wind, and he had already learned the wind legs. As for whether he can fly into the sky, it depends on Tong Yan's own cultivation level in the future.

Three days, a full three days of cultivation, Tong Yan has roughly mastered Feng Ling's legs, although compared to Sour Xiucai, the speed is still much slower, but compared to his previous speed, it can be called a world of difference.

If you just run fast and dodge skillfully, this can't really explain the power of Feng Ling's legs. This leg method can not only run and fly, but also fight!

"Little one, do you see the bronze statue in front of you? With your feet, kick it to pieces for me! ”

Hearing this, Tong Yan asked with some suspicion: "Master Jinpeng, are you sure I can kick it to pieces?" ”

Sour Xiucai smiled and said: "If you can't kick it, it means that you haven't really mastered Feng Ling's legs." As long as you kick it to pieces, you will be considered a teacher! Go ahead and believe in yourself! ”

Tong Yan nodded heavily, then took a deep breath and put on a posture of running hard.

As soon as he stood still, a cyclone immediately erupted around his feet. Seeing that his hind legs violently exerted force, his body suddenly rushed towards the bronze statue not far away like a gust of wind.

Seeing that the bronze statue was close at hand, he leaped upward, and a beautiful roundhouse kick instantly kicked the bronze man in the chest. I only heard a loud "bang", and when I looked closely, the bronze man was kicked apart by him.

Seeing this, Sour Xiu smiled with satisfaction, and then raised his legs and walked towards the door of the practice room.

Tong Yan was still immersed in the powerful power of Feng Ling's legs, and when he realized that Sour Xiucai was about to leave, Sour Xiucai had already walked to the door.

"Master Jinpeng, are you leaving?"

Sour Xiucai opened the folding fan in his hand, waved his head without looking back, and said, "You have already become a teacher, look forward to the next teacher!" Little one, I'm optimistic about you, don't let the teacher down! ”

Seeing this, Tong Yan hurriedly knelt on his knees, kowtowed three times and said, "The teacher is above, please accept the apprentice's worship." Please rest assured that the disciple will practice hard and not waste the hard work of the teacher! ”

Sour Xiucai didn't say anything, opened the door of the practice room and walked out directly. But there was actually a satisfied smile on his face, and his eyes were slightly moist.

It seems that this sour Xiucai is not only a "poisonous tongue", but also a sentimental person.

The new master has not yet arrived, and Tong Yan is not idle, he directly sat down cross-legged, and then devoted himself to cultivation.

The only thing he had to do now was to cultivate and learn new skills, and as for the rest of the things, he would leave them for later.

After about an hour, the next master finally pushed the door and walked in. This person's surname is Niu Dongchen, although he is not as tall as Di Fanchen, he also looks like one meter nine, and most importantly, he is very burly, to what extent? It's like a half-orc in the game, with big hands and big feet, and the skin of the body is bronzed, giving people a sense of strength just by looking at it.

He had a bald head and a brass ring on his nose. If you have a giant axe in your hand, it will feel absolutely powerful.

This person rarely speaks, and although he is also one of the ten Skywalkers, Tong Yan is extremely unfamiliar with him, because he has not communicated at all.

Niu Dongchen was dressed in a black sleeveless short coat, and his two arms like steel were exposed, which was very amazing. He was wearing no shoes, and his black trousers were a little shabby. It can be seen that he is a more casual person and a person who does not smile.

He walked in front of Tong Yan step by step with heavy steps, and the sound of "Tongtong" footsteps was like the sound of an elephant walking, as if the earth was trembling.

The moment the door of the practice room opened, Tong Yan opened his eyes. As soon as he saw the new master coming, he immediately stood up respectfully.

"Disciple Tong Yan, meet the teacher!"

Niu Dongchen glanced at Tong Yan, and then at the stone statues and bronze statues that were broken by Tong Yan's practice, and then he said unexpectedly: "You are not worthy of being my apprentice, and if you want to worship me as a teacher, use all your strength to defeat me!" As long as you can defeat me, I will teach you my proud skills. If not, you can stay here for three days and wait for the next Master to come!" ”

His voice was low and hoarse, and there was an irresistible glint in his eyes.

But Tong Yan had just barely learned the three skills, so how could he knock down an unfathomable Skywalker?

But it seems that this Niu Dongchen didn't mean to joke.

Tong Yan knew that no matter what, he had to fight with all his might!
