What happened on the top of the crack, Bai Chang didn't know at all, because as soon as he went down to the bottom of the crack, he was stunned by the scene in front of him.

What appeared in front of him was a terrifyingly large coffin, which may not be called a coffin, because this was actually an oversized wooden box, and the one that appeared in front of Bai Chang alone was more than four meters long and three meters wide.

The surroundings were completely shrouded in a layer of mist, and Bai Chang touched the coffin and found that the coffin was very thick, about twenty centimeters, and at the top of the coffin, there was a gap more than one meter wide.

Obviously, this should be caused by the thunder just now, Bai Chang tried, and the gap was just enough to get into a person.

Bai Chang remembered Guo Cripple's words, if this school was a place of eight yin, then it was very likely that this was the burial place of the spirit corpse.

Well, if you don't go into the tiger's den, you will get a tiger.

Taking a deep breath, Bai Chang stretched out his fingers and opened his spiritual eyes, and jumped into the coffin.

It was pitch black in front of him, but in Bai Chang's spiritual eyes, the surrounding scenery was still clearly visible.

The inside of the coffin was like a large room, and in each of the eight directions of the coffin, there was a kneeling corpse.

Carefully examined with the spiritual eye, the whole body of these eight corpses was as black as ink, the bones were complete, the hands were twisted behind their backs, their heads were raised to the sky, their necks were all broken by a knife, and their mandibles were wide open, obviously extremely frightened and frightened when they died.

In the middle of the coffin, there is also a recessed stone platform, on which a sarcophagus is placed.

The eight corpses are all kneeling down to worship this sarcophagus.

Under the corpse bones, there was a dark black groove, Bai Chang walked over and reached out to touch it, and soon understood.

This is the blood tank.

Eight corpses had their throats slit, and blood flowed from the blood tank to the stone platform in the middle, and finally into the sarcophagus.

Walking to the sarcophagus, Bai Chang found that on the stone platform and the sarcophagus, there were many strange runes densely engraved, which looked very ancient.

I'm afraid that this kind of rune will not be recognized by professional archaeologists, but Bai Chang just happens to recognize it.

This is because this is a special script that communicates with ghosts and gods, and it is called 殄文.

There are many sects in the world that practice secret arts, and the charms they draw use this kind of runes.

But the fact that there was such a thing under the school was completely unexpected.

This kind of coffin is called the Nine Yin and Yang in the Yin and Yang world.

What is Nine Yin to Yang?

To understand the meaning of these four words, we must first understand a common saying: ninety-nine to one.

In ancient Chinese feng shui culture, it is believed that the number of heaven and earth begins with one and ends with nine, nine is the ultimate, nine is the highest number, and if it exceeds nine, it will enter one and return to one.

This is to mean that the natural world repeats itself, and the cycle repeats, and the so-called ninety-nine return to one, and finally become the avenue, which is the meaning.

To put it simply, this cycle of Heavenly Dao is a kind of sublimation, a kind of reconstruction, a kind of rebirth, and a new starting point.

Nine Yin to Yang is to use nine human lives, set up a Dharma altar, take the meaning of ninety-nine to one, and ingest the lives of eight of them to make the ninth person "reborn".

Of course, this kind of thing that is similar to ghost magic has always only existed in legends.

Coincidentally, Bai Chang happened to know that this top-secret ghost technique of returning to the yin of nine lives would only be used by one sect in the world.

That is the fifth gate of the eight gates of yin and yang, the Yin Mountain Gate.

At the earliest, Yinshan Gate was born from the Taoist Yinshan School.

This Yinshan sect is a popular teaching, although it belongs to Taoism, it does not belong to Taoism.

Taoism and Taoism, although these two sound similar, are actually very different.

Fajiao, in fact, is a sect that spreads in the folk areas and has its own lineage due to different regional cultures, and this kind of sect does not have a fixed Taoist temple or cultivation place, and most of them travel in all directions, relying on the inheritance of masters and apprentices, and are hidden but not visible.

Most of the Yin-Yang Warlocks who have walked the rivers and lakes are among them, and the most obvious feature is that such people will never easily reveal their sect to outsiders.

Some of the more famous teachings, such as the Lushan School, the Liuren School, the Yaoshan School, the Huaguang School, the Yinshan School, the Great Sage Sect, the Luban Sect, the Meishan Shigong Sect, the Maoshan Jiulong Sect, etc., are the Taoist Teachings hidden in the folk.

And Quanzhen, Zhengyi, Shenxiao, Qingwei, Lingbao, Wudang, and other famous sects are Taoism within Taoism, which is characterized by having a fixed Taoist temple and a fixed place to preach.

For example, ordinary people rarely see the Taoist priests of Wudang Mountain walking among the people, and even if these disciples of the so-called famous sects come out to do things, they will always talk about the teacher, lest others do not know.

This is the difference between Fa and Taoism.

And this Yinshan Sect is the most mysterious and weird sect in the Dharma Sect. Its spells are heavy on yin, so that the flag will be used by the five ghost soldiers, and he likes to practice in the graveyard and the yin land, which are extremely yin places, and borrow the material energy of yin such as corpse bones and human blood to practice.

To put it simply, Yinshan Gate is a sect of ghosts.

Therefore, the Yinshan Gate is a cult, ranking the fifth gate of the eight gates of yin and yang, which is recognized by everyone in the world.

In fact, according to the strength of Yinshan Gate, it can be ranked in the first few places, but Yinshan Gate has always been scarce, and it is secretive, and the disciple of the door Shenlong sees the head but does not see the tail, in view of this, he has to rank the fifth gate, above the Bai family.

Especially in recent years, Yinshanmen is even more hidden, and it is rumored that the head of this generation, Yin Nineteen, has been missing for more than 20 years.

Some people even say that because the Yinshan Gate is too damaging to Yin Virtue, it has already died and died, and the whole gate has been destroyed.

Of course, the world says that there are no good people in the Yinshan Gate, and even the Yinshan Gate is deeply hated, and even the Yin and Yang Eight Gates are very jealous of the mysterious and moody Yinshan Gate.

However, Bai Chang didn't think so, he always felt that the good and evil, good and evil in this world, were by no means determined by the spells and cultivation methods in the sect.

The so-called law has no good or evil, but people have good and evil, and the distinction between good and evil actually only lies in people's hearts.

However, on the shore of the abandoned lake of this school, deep underground, there would be the ghost magic of the Yin Mountain Gate, which really surprised Bai Chang.

An old corpse, and in this kind of eight-yin land, not to mention the pattern of nine yin returning to yang, so, is the corpse in this sarcophagus considered a spirit corpse?

If so, then the second ingredient that the immortal pointed out the way will be settled......

Thinking of this, Bai Chang gradually curved the corners of his mouth upward, revealing a happy expression.

Without hesitation, he immediately jumped onto the stone platform and found the pivot where the sarcophagus opened......
