After the Kang family dedicated the city to the command of Emperor Dingyuan, a large number of resentful spirits would appear in the first stage of the owl every night. Although these resentful spirits are not harmful, they are ghosts crying and howling wolves all night long, which makes the people living in Liangcheng fearful.

Because Emperor Dingyuan had just established the Dachang Dynasty, the Kang family was worried that the people's complaints would lead to the court's questioning, so they could only look around for a solution. Later, under the guidance of a certain master, he spent a lot of financial resources and manpower to go to Fengling Mountain to pick a sealing spirit stone to replace the high platform originally used to behead the public, in fact, it was to suppress the resentful spirits that would haunt every night.

On the way to Xiaoshoutai, Ah Mo told Su Mu that from the map of Liangcheng, the three altars were located in the north, southeast and southwest of Liangcheng.

Ah Mo jumped to the roof of the next house and stopped: "Taishou Mansion is located in the north of Liangcheng, Peach Blossom Garden is located in the southeast, and Xiaoshou is located in the southwest.

Su Mu didn't understand, "Triangle? What do you mean?"

Yueyan understood: "Three lives and all things?"

Although Yueyan doesn't know how to do strange arts, after all, she is also a person in the different ways, so she naturally knows the meaning of "three lives and all things". As the saying goes, the Tao gives birth to one, one life to two, two to three, and three to all things, and the number three also has a special meaning in the different paths.

For ordinary people, even numbers are auspicious numbers, so there are sayings such as good things come in pairs, but in different ways, the real auspicious numbers are not even numbers, but singular numbers, such as three.

Although Su Mu didn't understand the special meaning of Sanhe triangle in different arts, he knew that he could understand it, so he remembered the eight-character key of the hidden art, "Dantian is the tripod, and the ankles are the altar".

The position of the dantian is in the abdomen, and the ankles of the feet are on both sides, which also happens to form a triangle, which is the basis of the hidden technique, that is, stability.

Cryptography used to be called the art of mystery, and people who are skilled in using stealth come and go without a trace, and it is rumored that the highest realm can even reach the level of stealth, and the mystery of stealth exists in those eight words.

In addition, the upper and lower six layers of internal power are called Liuhe, which seems to be a double number, but it is also a double three, and the nine layers of different magic power are three three, and they are all inseparable from three.

When Ah Mo explained to Su Mu, she was also recalling, as a person in the alien realm, she didn't know all the magic techniques, she just vaguely remembered where she seemed to have heard this way, strictly speaking, this belonged to a kind of inner array enchantment in the magic arts. Look at the book

The inner array enchantment is normally based on the round heaven and place, and the southeast, northwest, and north sides are set up as columns, and purely from the graphic aspect, it is a combination of circles and squares. Although there are also triangles, they are rarely used, so Ah Mo does not know about them.

Yue Yan proposed, "Sister Moo, why don't you summon the Old Ancestor again?"

Ah Mo said: "Spiritualism not only requires a lot of magical power, but also consumes people's lives, not as a last resort, I must keep my magical power and physical strength, otherwise, if we encounter a strong enemy in the future, we will be in trouble."

Subsequently, the three of them quickly rushed to the location of the first platform, and sure enough, they found a boulder, the size of which was about the same as the original decapitation platform. It would take a lot of time just to find a stone of this shape on Fengling Mountain, let alone transport it back from Fengling Mountain, which was located thousands of miles away in the Plain.

"Yueyan, you stand here and don't move, don't get close to the first platform," Ah Mo became nervous, "Zhongguan Su, please look around for another spirit sealing stone, I'll go up and take a look."

Yueyan felt that there was obvious concern in Ah Mo's words of admonishment, that is, the relationship between her sister and her sister, which made her more and more confused.

At the moment when Ah Mo jumped on the first stage, she frowned, and subconsciously looked at the spirit skull lantern in her hand, but the spirit skull lantern did not react, she muttered, "It's not right."

Su Mu ran around the first stage of the owl quickly, and did not find the new spirit sealing stone set up a year ago, but at this time, Yueyan smelled the fragrance of peach blossoms coming from the lower edge of the first platform, so he guided the two to find it.

Su Mu came to the edge of the owl's first platform, and then found that the surrounding area was covered with gravel, and the peach blossom fragrance was emanating from the gravel.

Ah Mo jumped off the first stage of the owl and lifted it

The skull lantern was lit, and when the lantern was lit, it illuminated the rubble that had been laid on the ground, and the roots of the peach tree were immediately visible from the rubble.

Ah Mo carried the lantern and walked along the location of the root: "Follow the root of the tree to find the peach tree."

Under the light of the spirit skull lantern, the three of them followed the roots of the peach tree under the ground to find a dilapidated mansion next to it. This kind of house next to the execution site is called "full-time courtyard", which actually means whole corpse, and was renamed "time" in order to avoid the word corpse.

People can't die without a whole body, so if the family of the beheaded prisoner is willing, they can pay someone to re-stitch the prisoner's head and body together.

The three of them followed the roots of the tree into the full-time courtyard, and at a glance they saw the huge locust tree standing in the middle of the courtyard. Folklore has it that the locust tree has a very strong yin qi, although it is said to attract the undead, but it also has the meaning of trapping the undead, so some places will be planted with locust trees, so that those undead or resentful spirits who have not entered the Nine Domains can be trapped around the locust tree.

It's just that not only are there no undead around this locust tree, but the roots of the peach tree are also directly connected to the roots of the locust tree, which makes the three of them feel surprised.

Could it be that the altar here is not a peach tree, but a locust tree?

Ah Mo raised the spirit lantern and approached the locust tree, and under the green light, he finally found that there was a peach tree hidden in the trunk of the locust tree.

Su Mu was surprised: "What's going on?"

Yueyan also looked at Ah Mo, there was a peach tree hidden in the locust tree, what was going on?

Ah Mo didn't understand either, but said, "If we want to prevent the demon underworld from descending, we have to destroy the altar, let's destroy two places first, leaving only the one in the Taishou Mansion, and at least one entrance and exit, Zhongguan Su, what do you think?"

Su Mu didn't understand very well, but at least for the time being, Ah Mo was in the same boat as him, and it didn't do her any good if the horse and the princess couldn't find it, so she agreed.

After having the experience of destroying the altar last time, this time Su Mu directly took out the fire talisman gun.

Ah Mo subconsciously protected Yueyan and retreated, this move made Yueyan feel even more surprised, she had realized that Ah Mo cared about her more than ordinary peers.

Is there any direct connection between himself and Ah Mao? Could it be that it was because of this connection that he was sent to Ah Mo after the mission failed?

However, after Su Mu activated the fire rune gun mechanism, the fire rune gun did not respond, and he couldn't fiddle with it for a long time. This magical firearm belonged to Tang Xiaohao, Su Mu didn't understand its principle at all, and he didn't know that it was because he had no relationship with the talisman bullet, so he could only put away the fire talisman gun and look at Ah Mao.

Ah Mo could only throw the rune paper towards the locust tree, and after reciting the incantation, although the rune paper exploded smoothly, it only exploded the trunk, and when Ah Mo stepped forward to check, the huge locust tree suddenly let out a scream.

The sudden scream startled the three of them, because the sound was so harsh that it felt like they were about to burst their eardrums, so the three of them covered their ears and ran out of the courtyard.

At the same time, the people who were still in the Peach Blossom Garden, Childa and the Taishou Mansion also heard the continuous screams.

The strange scream spread throughout the city in an instant, and even Aoki and Bai Shihui, who were riding to the camp outside the West City Gate, heard it, and the horses they were riding were frightened by the scream and raised their front hooves and neighed.

Čerda grabbed his weapon and pushed open the window to look at the source of the sound, which was the remains of the destroyed spirit sealing stone, and the ironclad guards in the Taishou Mansion also found that the screams came from the island in the middle of the lake in the backyard.

The scream continued for a while and then disappeared, and Aoki and Bai Shihui, who had already arrived at the West City Gate, finally calmed down the frightened horses and looked around, not knowing what was going on.

At this time, Aoki noticed that there was a vision in the sky over Liangcheng, the sky was half clear and half cloudy, the clear half was hung with a full moon, and the half of the dark clouds also suspended something like the moon, but it was blood red.

Aoki secretly screamed badly, and reminded Bai Shihui, who was still in a daze, to follow, and immediately rode towards the Tianqian army camp outside the West City Gate.

Let's talk about Sumu and Amo, which are located in the southwest of Liangcheng

and Yueyan, after the screaming stopped, the three of them put down their hands covering their ears and stared at the big locust tree in the full-time courtyard in front of them.

Su Mu, whose head was still buzzing, asked, "What was that just now?"

The surrounding houses were lit up by fire, and it was clear that the screams had woken up the people of the city.

Yueyan counted the time and felt that something was wrong: "Sister Moo, it's early morning now, why ......?"

Ah Mo raised his hand and pointed to the sky, and the three of them also found that the sky was split in two, but what they didn't know was that now in the entire land of the Nine Plains, it was only the sky above the Heavenly Trunk Dao Liang City that was split in two.

Su Mu was completely confused: "What the hell is going on?"

Ah Mo analyzed: "If the words of the old ancestor are not wrong, this is the harbinger of the Demon Underworld descending on Liang City, I know what those screams just now are."

Yueyan immediately asked, "What is it?"

Ah Mo said, "Demon Song."

Su Mu asked, "What is the Demon Song?"

"Whether it is an elf or a demon spirit, when they are in danger or in a state of extreme excitement, they will make this kind of chirp, like a wolf howling."

Yue Yan's face changed suddenly when she heard this, and those screams before were obviously not from a single monster, but countless monsters, that is to say, there may be many monsters lurking in Liang City, or are those monsters who died and entered the demon underworld become excited because they can return to the Nine Plains Human World?

Ah Mo took out the rune paper: "No matter, let's destroy this locust tree first, the inner array enchantment set up by the caster is too strong, and my magic power can't deal with it, so I can only use stupid methods."

The three of them immediately entered the full-time courtyard, split all the wooden furniture, tables, chairs and benches, and then piled them on top of the big locust tree and set it on fire.

However, the big locust tree was not as flammable as they thought, and even in the midst of the fire, it was only the bark that was blackened.
