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

Just this glance scared him.

The pool has no bottom, and of course it is not water inside.

The more you dive, the more obvious the power of the prehistoric world will be.

The two white and black energy, which are clearly divided on the surface of the pool, become entangled under the pool, and you can no longer distinguish between black and white when you reach the depths.

Everything becomes dark and difficult to distinguish, as if there is no boundaries, no sky or earth here.

Qi Wufei suddenly heard a strange roar.

The sound was not loud, but it hit his chest like a hammer, almost spurting blood out.

A huge shadow appeared in the depths of the darkness. I don’t know what it was, but in just a flash, it disappeared again.

Qi Wufei stopped there and waited for a while. There was no movement and he didn't dare to dive anymore. He swam upwards and returned to the pool.

After coming out of the pool, he walked towards the Ganmen again.

The first line of Qian hexagram has already lit up, and he wants to try whether he can light up the second line.

According to previous guesses, after all Liu Yao is lit, the door can be opened.

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

When he faced the golden light emitted by the first line of Qian Gua, he saw the line again:

"Don't use the hidden dragon in the first nine."

This is the first line of Qian hexagram, so Qi Wufei certainly knows it.

The first chapter of "Basics of Mathematics" is about the knowledge of Fuxi and the Eight Trigrams. Fuxi's creation of the hexagrams and King Wen's repertoire of Yi are the general outline of all mathematical techniques.

Since childhood, Wu Jizi taught him to memorize the Book of Changes, saying that this is the source of all transformations.

All the hexagrams and the yao words of the entire sixty-four hexagrams of the Book of Changes are all memorized like flowing.

On the ninth day of the lunar calendar, do not use the hidden dragon.

On the ninth day of the first nine, it is not about the day, but refers to the first line of the Qian hexagram.

The first means the beginning, which refers to the position of this line and ranks first in the hexagram.

Nine means that this is the Yang line.

The most important thing in the Eight Trigrams of the Book of Changes is yin and yang, the so-called one produces two, two produces three, and three produces all things.

When drawing a hexagram, two broken short horizontal lines (—) represent yin, that is, even numbers; one long line (1) represents yang, that is, odd numbers.

If expressed in numbers, six represents yin and nine represents yang.

For example, the six lines of Kun hexagram (upper and lower) are all yin, and its first line, that is, the lowest line (—) is a yin number, is called "first six";

The second line is called "Six Two";

The third line is called "Six Three";

By analogy, the top line, that is, the sixth line, is called "upper six".

The six lines of Qian hexagram (upper and lower) are all yang, so its first line is called "first nine".

Every hexagram in the Book of Changes has a hexagram, and every line also has a yao word.

The lines of the six lines of Qian hexagram are:

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

Ninety-two, seeing the dragon in the field, it is better to see the master;

Nine Three, a gentleman works hard all day long, and is vigilant at night;

Nine Four, or jumping in the abyss, without any fault;

Nine Five, the flying dragon is in the sky;

In the upper nine, Kanglong regrets.

"Do not use the hidden dragon" is the line word for the Qian hexagram "first nine" of the first nine.

From the perspective of hexagram, the first line of Qian hexagram is at the bottom, and the so-called yang is hidden below, which is not available, just like a dragon is hidden in the sea. You need to wait for the opportunity to fly to make a difference.

But Wu Jizi once said that the explanation of the hexagram and the yaoci is not dead, otherwise everyone would understand the Book of Changes.

Qi Wufei narrowed his eyes and walked towards the golden light.

At this time, he heard the magical spells in his ears again.

The closer you get, the more obvious the sound will be and the greater the impact of the spiritual consciousness will be.

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

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

As soon as his hand touched the door, the murmuring sound suddenly increased, and a lot of information poured into his mind and exploded.

He felt that he had become fragments and melted into the golden light...

...

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

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

You can still hear murmuring from afar in your ears.

"Don't use the hidden dragon in the first 9th day!"

"Don't use the hidden dragon in the first 9th day!"

"Don't use the hidden dragon in the first 9th day!"

...

Qi Wufei repeatedly recited this line of words, and some strange things surging in the sea of ​​consciousness, and then entered the Ren and Du meridians from the brain along the spinal nerves and vagus nerves, circulating in the sky with his own qi.

He seemed to understand the distant ethereal and magical words.

It's a spell!

Qi Wufei became excited.

This is a spell!

A spell!

The power of this spell has entered his body and is used by him.

"Don't use the hidden dragon!"

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

When this spell takes effect, the user will hide in the abyss like a dragon, hiding himself.

Qi Wufei still remembers that when he went to the City God Department, Qin Yubai saw through his cultivation at a glance.

After just one day, his magic power has improved from the level of a first-grade human immortal to a second-grade level, almost doubled. It would be difficult to explain if Qin Yubai discovered it.

He has always wanted to find a magic weapon that can block the fluctuations of mana. Now he doesn't need it anymore, just recite a spell and can do it.

Of course, spells consume mana.

Qi Wufei immediately tried it and silently chanted "Don't use the hidden dragon". His thoughts drove those ethereal demon sounds, and an invisible layer of divine light protected his body.

When the spiritual consciousness saw that his magic power had dropped a little, it changed from 518/518 to 517/518.

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

This effect is even better than he expected.

Mana is like physical strength. After being consumed, even if no measures are taken, it will slowly recover.

His own recovered mana just offset the mana consumed by the spell, which means that this magic that hides the fluctuations of mana can always be blessed on him.

Qi Wufei was very satisfied. This was better than bringing a shielded magic weapon. After all, magic weapons take up space and are easy to lose.

The first line of Qian hexagram can obtain such a magical magic, so what about other line of line?

You should know that the entire Book of Changes has a total of 64 hexagrams and 384 lines. Does it mean 384 kinds of magic?

Even if the eight trigrams correspond to the eight gates of the world in the mirror, if one line is lit for each hexagram, one spell can be obtained, then there are forty-eight kinds after all light up.

The second line of Qian hexagram is: "Nine Two, see the dragon in the field."

What kind of spell would this be?

Qi Wufei was very curious.

But he was very calm and knew the truth that one should not be too greedy in life.

The things brought by the magic sound mantra in his mind have not been completely digested. If he does it again, he may not be able to control his soul and become possessed by the demon.

What's more, his potential has been fully explored in the Tai Chi Pool, and his magic power will not increase again. It is impossible to light up the second line of Qian Gua in the short term.

The Seven Spiders have woken up. This is the money tree of Huanghuaguan, so they have to be protected.

You can't let them run around anymore. If you take pills and die of suffocation, it will be unbeautiful.

Even if a spider only spits one or two silks a year, according to the price given by Duanmuwei, it will earn more than 80,000 purple coins a year.

He remembered that if you can work hard on feed, you can increase the yield to a single spider with one or two silk per month.

A single spider produces one liang a month, one liang a liang a year, and seven spiders produce more than eight jin a year, which can be sold for nearly one million purple coins.

Damn, I'll earn a million yuan a year?!
Chapter completed!
