This story is purely fictional, and any similarities in the plot are purely reference and coincidence.

The Book of Hetuluo, formed between about 4000 BC and 2000 BC. At that time, the people of the world experienced countless wars and disputes, and their lives were devastated.

Later, after many years, in order to protect these two mysterious heavenly books, there was a hermit who was granted the mandate of heaven, and lived in seclusion among the mountains all the year round with the original Hetuluo book.

This hermit, known as Xuanji, found a secret cave on Yuxu Mountain, which is full of strange peaks and valleys, and lived here in seclusion all the year round, living an isolated life, just to keep the secret of Hetuluoshu, until one day in the future, he will teach the real Hetuluoshu to a person who is related to it, that is, the descendant of Tianshu, so that it can be passed on for centuries and benefit the people of the world.

In order to protect this magical book of heaven, this Xuanji hermit drank the spring water in the stream in the mountains, and fed on wild fruits, birds and animals. Usually sit cross-legged in the cave, meditate and practice, and study the subtleties of the Hetuluo book in his spare time to comprehend the magical mystery of this heavenly book.

Sometimes the hermit would repair the cave, and it took him several years to install a stone door in the cave, and on top of the stone door, a mechanism was set up, which was a peculiar combination of locks, which had to be rotated on a circular lock plate with the correct combination of codes to open the cave.

Next to this hidden cave, there is a white snake that has been cultivated for five hundred years, guarding the safety of this Xuanji hermit every day. Of course, this white snake was also ordered by the sky to protect the safety of the Book of Heaven, and it was accompanied by the Xuanji hermit day and night, and the lone lamp was guarded, so it spent a time of guarding the cold and heat.

One day, on a thunderstorm night, the white snake gave birth to a nest of snake eggs, so the white snake stayed in the nest without eating or drinking, and hatched the baby snake. On the sixtieth day, the little snake broke out of its shell, and there were eight little white snakes, one of which was the last to crawl out of the eggshell.

When it broke out of its shell, the big white snake was relieved and stretched out its tongue to lick the body of the little white snake. I saw that the little white snake's whole body was covered with neat scales, the white scales were shining with a faint golden light, and there were a few thin black patterns on the forehead, as if it was the eyebrows of the little white snake. The appearance of the little white snake is very cute, its eyes are round and black, and it is bright, like two little black beans.

Because the little white snake broke its shell late, it was not big, and compared with her siblings, it looked weaker. Therefore, every time the big white snake took the little snakes out to forage, he asked the little white snake to stay next to the cave where the hermit lived, which was a small hole that communicated with the cave, and watched the hermit practice, so as to be contaminated with a little blessing, so as to bless the little white snake's health and health.

The little white snake is very well-behaved, and every time he honestly stays in the small cave, watching the hermit cultivate from afar.

The cave where this Xuanji hermit hid was not very large, but after several repairs, it was repaired very clean and tidy, and it was drier and more comfortable than ordinary caves. And on the wall opposite the entrance of the cave hangs a portrait of the ancestor of Fuxi.

In the portrait, the ancestor of Fuxi is wearing a leopard skin, sitting upright on a rock, with long hair and beard, a kind face, and a sideways look at the bottom of the rock, as if he is quietly watching the lives of the people in the world, and his heart is pitying.

Below the portrait of Fuxi ancestor is a wooden incense case, on which is placed a simple and extraordinary sword, the sword is covered with an antique scabbard, the scabbard is inlaid with a few light blue turquoise, and the sheath is also engraved with some peculiar cloud-like patterns.

At first glance, it looks like a hilt studded with mammoth ivory, and ends in a bronze round skull, on which is inlaid with a translucent sapphire that shines in the light that enters the room.

The sword's gauntlet is a mountain-like shape with a dragon-shaped pattern carved on it, and the sword looks very powerful from a distance.

The little white snake had never seen the Xuanji hermit draw this sword, so she never knew what the sword body looked like, whether it was cold and shining or sharpening iron like mud, or whether it was triggered and broken, she didn't know at all.

It's just that the little white snake is very curious, since the appearance of this scabbard and hilt is so simple and extraordinary, then the sword body and blade must be very peculiar and sharp.

On the incense table is also a rosewood box containing a ruby necklace. The necklace is an ancient silver clasp chain with a round silver set set with a blood-red gemstone at the end.

This ruby will refract the brilliance of stars in the sunlight that obliquely reflects into the cave, but the red color always reminds the little white snake of the bright red blood, and she can't help but wonder repeatedly whether this ruby is condensed by whose blood.

Moreover, the color of this gemstone is so magnificent, and even looks very charming, does it have some strange effect?

When the little white snake saw this necklace, she couldn't help but think about it, and the red gem was too tempting for her.

If she had a pair of hands, she would have been tempted to rush up, pick up the necklace, stretch out her tender fingers, and stroke it carefully.

Savor the coolness of the gemstone, and admire the alluring bright red color and sparkle of light.

She was always wondering if there must be some secret hidden in this magical gem, but she didn't know it, otherwise why Uncle Hermit would have carefully hidden it in that rosewood box, and carefully presented it on the incense table, as if he were offering it to the gods.

Little White Snake was full of curiosity, and she wanted to find out what secrets were hidden in these things.
