Qi Hufei soaked in the Tai Chi pool for a while, and even dived down to take a look.

Just this glance startled him.

The pool has no bottom, and of course there is no water in it.

The further down you go, the more obvious the power of the wilderness becomes.

The white and black qi that is clearly divided on the surface of the pool become entwined at the bottom of the pool, and it is no longer possible to distinguish black and white in the depths.

Everything became dark and indiscerning, as if there was no boundary, no heaven and no earth.

Qi Hufei suddenly heard a strange roar.

It wasn't loud, but it hit him in the chest like a hammer, and he almost spurted out a mouthful of blood.

A huge shadow appeared in the depths of the darkness, I don't know what it was, but it only flickered, and then disappeared.

Qi Hufei stopped there and waited for a while, but there was no movement, and he didn't dare to dive any further, so he swam towards and returned to the surface of the pool.

Coming out of the pool, he walked towards the dry door again.

The first line of the Qiangua had already lit up, and he wanted to see if he could light up the second line.

According to the previous guess, after all the six pillars are lit, this door can be opened.

The Tai Chi Pool is already so magical, what is hidden behind this door?

When he faced the golden light emitted by the first hexagram, he saw the line again:

"On the ninth day of the first month, don't use the hidden dragon."

This is the first word of the Qiangua, of course Qi Hufei knows.

The first chapter of "The Basics of Mathematics" is about the knowledge of Fuxi and Bagua, Fuxi Chuanghexagram, King Wen Yanyi, is the general outline of all mathematics.

Since he was a child, Wujizi taught him to memorize the Book of Changes, saying that this is the source of all things.

All the hexagrams and epigrams of the sixty-four hexagrams of the entire I Ching are all memorized backwards.

On the ninth day of the first month, don't use the hidden dragon.

On the ninth day of the first month, it is not about the day, but about the first hexagram.

Chu, which means the beginning, refers to the position of this hexagram, ranking first in the hexagram.

Nine, which means that this is the yang line.

The most important thing in the I Ching gossip is yin and yang, the so-called life two, two birth three, and three birth all things.

When drawing a hexagram, two broken short horizontal lines (--) represent yin, that is, even numbers; A long line (one) represents yang, i.e., an odd number.

Expressed as a number, six represents yin and nine represents yang.

For example, the six lines of the Kun hexagram (☷ upper ☷ and lower) are all yin, and its first line, that is, the bottom line (--) is the yin number, which is called the "first six";

The second line is called "Sixty-two";

The third line is called "Liusan";

And so on, to the top line, that is, the sixth line, is called the "upper six".

The six lines of the Qiangua (☰ upper ☰ and lower) are all yang, so its first line is called "the ninth day of the first month".

Every hexagram in the I Ching has a hexagram, and every hexagram also has a hexagram.

The words of the six hexagrams are:

On the ninth day of the first month, do not use the hidden dragon;

Ninety-two, see the dragon in the field, and see the lord;

Ninety-three, the gentleman is dry all day long, and the evening is timid;

Ninety-four, or leaping in the abyss, no blame;

Ninety-five, the flying dragon is in the sky;

On the ninth, Kang Long has regrets.

"Don't use the hidden dragon" is the epigram of the "first nine" of the Qiangua.

From the hexagram point of view, the first hexagram is at the bottom, the so-called yang is submerged, and it is not available, just like the dragon diving in the sea, and it needs to wait for the opportunity to fly to the sky in order to make a difference.

But Wujizi said that the explanation of hexagrams and hexagrams is not dead, otherwise everyone would understand the I Ching.

Qi Hufei squinted his eyes and walked towards the golden light.

At this time, he heard the magic sound spell in his ears again.

The closer you go, the more pronounced the sound becomes, and the greater the impact on your senses.

Fortunately, his mana has recovered at this moment, and it has doubled compared to before, so he can better protect himself.

Walking all the way to the door, resisting the erosion of the magic sound, Qi Hufei was about to reach out to push the door.

As soon as his hand touched the door, the murmuring magic sound suddenly intensified, and a lot of information poured into his brain, and it exploded with a bang.

He felt like he had been reduced to pieces, dissolved in the golden light......

……

When he woke up, Qi Hufei found himself in the Dan room, maintaining a meditative posture.

The seven spiders had also woken up, and they were lined up in a row, lying on the floor in front of them, staring at him curiously with fifty-six eyes, large and small.

Whispers could be heard faintly in the distance.

"On the ninth day of the first month, don't use the hidden dragon!"

"On the ninth day of the first month, don't use the hidden dragon!"

"On the ninth day of the first month, don't use the hidden dragon!"

……

Qi Hufei repeated this sentence, and some strange things surged in the sea of consciousness, and then entered the second vein of Ren Du from the brain along the spinal nerve and vagus nerve, and circulated with his own qi in Zhou Tian.

He seemed to understand the distant ethereal whispers.

It's a spell!

Qi Hufei became excited.

It's a spell!

A spell!

The power of the spell had entered his body and was used by him.

"Don't use the hidden dragon!"

This is not only a mantra, but also a mantra.

When the spell takes effect, the user dives into the abyss like a dragon, hiding himself.

Qi Jufei still remembered that when he went to the City God Division, Qin Yubai saw through his cultivation at a glance.

After only one day, his mana had improved from the level of a first-grade human immortal to a second-grade, almost doubling, which would be difficult to explain if Qin Yubai found out.

He had been looking for a magic weapon that could shield mana fluctuations, but now he didn't need it, he could do it with just a spell.

Of course, spells consume mana.

Qi Hufei immediately tried it, and silently recited "Don't use the hidden dragon" in his mouth, and his mind drove those ethereal magic sounds, and there was an invisible layer of divine light to protect his body.

The Divine Consciousness saw that his mana had dropped a little, from 518/518 to 517/518.

After a while, the mana returned to 518/518, and then dropped a little more, becoming 517/518......

It worked even better than he expected.

Mana is like physical strength, and after it is consumed, it will slowly recover even if you don't take measures.

The mana he recovered by himself just canceled out the mana consumed by the spell, that is, this spell that hid the fluctuation of mana could be blessed on him all the time.

Qi Hufei is very satisfied, this is better than bringing a shielding magic weapon, after all, the magic weapon takes up space and is easy to lose.

One hexagram can obtain such a magical spell, but what about the other words?

You must know that the entire Book of Changes, with a total of 64 hexagrams and 384 hexagrams, does it mean 384 spells?

Even if it corresponds to the eight trigrams on the eight doors of the world in the mirror, each hexagram has six lines, if one line is lit up, you can get a spell, then there are forty-eight kinds after all are lit.

The second hexagram is: "Ninety-two, see the dragon in the field." ”

What kind of spell could this be?

Qi Feifei was very curious.

However, he is very calm and knows that he can't be too greedy.

The things brought by those magic sound spells in his brain had not been completely digested, and if he tried again, he would probably not be able to control the primordial spirit, so he would go mad.

What's more, his potential has been fully tapped in the Taiji Pool, and his mana will not increase again, and it is impossible to light up the second hexagram in the short term.

The seven spiders have woken up, this is the cash cow of Huanghuaguan, and it must be protected.

They can't be allowed to run around anymore, in case they die after taking pills, it won't be beautiful.

Even if a spider only spits out one or two threads a year, according to the price given by Duanmuwei, it will have an income of more than 80,000 purple coins a year.

He remembered that Master had said that if he could work the feed, he could increase the yield to one or two threads per month for a single spider.

A single spider produces one tael a month, an annual output of one catty and two taels, and seven spiders produce more than eight catties per year, which can be sold for nearly one million purple coins.

I'm rubbing, that's a million a year?!

Then what kind of work do I do, what kind of work do I go to?
