After dealing with the withered bone demon, Lu Zhong immediately took out a small leather bag and packed up the bone powder scattered in the passage, preparing to sift it through a sieve after returning so that the bone crystals inside could be separated.
Bone crystal is a kind of weapon refining material. It is the precipitate of Yin Qi in the body of the withered bone demon. It can be ground into powder and added to the ink. It is a rare conductive agent.
Talismans with conductive agents added will have better spiritual conductivity.
Transmission agents like this are sold for money in the market, so if you encounter one once in a while, you can't miss it.
Li Dong was also collecting bone powder on the ground. Obviously he also knew the value of bone crystals.
Afterwards, the two continued to move forward.
After crossing the vat of bones that were still everywhere, they never encountered the withered bone demon again. Even the Yin Qi in Lu Zhong's vision slowly began to fade.
Perhaps he had gained something, and Li Dong's face finally became less ugly.
At this moment, a black obelisk appeared in front of him, very low and only over a foot high.
"The obelisk of the dead, this is the entrance to the mass grave." Li Dong pointed to the obelisk and spoke in a heavy tone.
Lu Zhong stepped forward and looked at the obelisk carefully.
The texture of the stele should be obsidian, with a sacrificial text engraved on all sides.
A memorial article should be used for narrative. It begins with "In the 147th year of the Southern Calendar, a battle with demons took place on the banks of the Lishui River." It tells part of the content of that great battle, using the words "the blood is overwhelming, the corpses are everywhere."
Words such as "stacked wilderness".
Just by reading the few words in this memorial, he could feel the brutality of that battle.
"The soul is like the soul, returning to my hometown..."
Lu Zhong recited this sentence in the soul-calling ritual text, and finally understood the original intention of the monks to hold the burial.
Probably because they were afraid that the deceased would lose his body and the lost soul would never be able to return to his hometown.
According to the ancient monks, after death, people go to the underworld. Only by having a body as before life can we protect the easily lost soul from dissipating, and then we can find the way back to our hometown under the guidance of the hometown soul summoning platform.
.
"Is there really a hell after death?" Lu Zhong suddenly thought of a question.
If there really is a netherworld after death, will there be a corresponding underworld, and will the sky be filled with immortals and gods?
He thought no more, this question was destined to remain unanswered.
Turning your attention to the entrance of the mass grave, there is a closed bluestone door.
There are many traces of talismans remaining on the door. Judging from the year, they should have been left when the tomb was originally built. As for the specific function, it is not clear. It should be related to summoning spirits.
In the middle of the gate, there are seven grooves.
There is a lot of gray-white powder in the groove, which is obviously the kind of powder left after the spiritual stone exhausts its spiritual energy.
Obviously, if you want to open the bluestone door, you must fill the groove with spiritual stones.
Lu Zhong used his qi-gazing technique to glance behind the door, his face full of solemnity.
This scene was seen by Li Dong, who cast a questioning look.
"I saw a very strong yin energy behind the door. If nothing else, it must be a withered bone demon!" Lu Zhong told the result of what he saw without any reservation.
He took two steps back, not forgetting to make sure the passage he came from was safe so as not to block his retreat later.
Then, he murmured for a while, and at the same time, he began to perform the kneading ritual with his hands.
After a while, fireballs condensed in front of him, and the number reached fifteen.
Although it is not as good as Yu Qing from Qingyang Clan, it is still the result of his long-term practice.
"Okay, open the door." Lu Zhong said in a deep voice.
With the power of Qingyang Fire Rain Technique, even if there is a group of withered bone demons hiding behind, they will never be able to stop this wave of fireballs.
When Li Dong saw the fireballs, a look of surprise flashed in his eyes.
When Yu Qing taught the Qingyang Fire and Rain Technique to the casual cultivators on the birthday of Patriarch Qingyang, he was also present and listened in. He once had a sweet dream of learning this technique.
But he never thought that this secret technique that he could never learn would be used by Lu Zhong.
Li Dong's mood at this moment was indescribably complicated.
Thinking of his dying son again, his expression became firm again, he picked up the last spiritual stone and said in a deep voice: "Fellow Daoist Lu, I only have the last spiritual stone left."
"Put it in, I'm ready!" Lu Zhong nodded.
Hearing this, Li Dong inserted the spirit stone into the groove.
Suddenly, light patterns began to light up on the surface of the bluestone door, and they gathered into a circle of symbols with unknown meanings.
Immediately afterwards, there was only a sound of "Geleng Leng" machinery, and the bluestone door slowly retracted into the wall on both sides.
Almost at the same time, the two of them saw the green flames behind the door, and their scalps suddenly became numb.
Without hesitation, Lu Zhong put his fingers together and pointed forward.
"go!"
The fireballs floating around him began to shoot out one after another.
A hot storm blew in, and the blazing waves of fire began to roll behind the door, spitting out fiery snakes from time to time, burning everything in the place where they spread.
Lu Zhong didn't stop and added another shot of Qingyang Fire Rain Technique.
After doing this, he retreated into the passage and waited for the flames to subside.
At this moment, there was a sea of fire behind the door. The heat wave continued to roll up the ashes, which looked like white mist.
Gradually, the fire died down.
Lu Zhongchao took a cleansing charm and found that there was calm behind the door.
The pale ashes inside were piled on the floor, probably as thick as half a finger.
One can imagine how many skeleton demons were standing behind the door just now.
"Let's go in."
For some reason, Li Dong's expression suddenly became calm.
The sudden change in the other party's mood made Lu Zhong feel secretly vigilant. He immediately pinched his hand to detect malicious intent, but there was no reaction in his heart.
"strangeness……"
He raised his head in confusion and found that Li Dong had already entered behind the door, so he followed him.
Behind the door is a straight passage. Because it was blasted by two Qingyang Fire and Rain Techniques, part of the earth wall here has now turned into glass, and the figures of the two people can even be clearly reflected.
Walking forward along the passage, about a hundred feet away, they came to a huge space.
It is worthy of the name of a mass grave. There are countless human bones everywhere you look. It is hard to imagine how many people were buried here.
As if he thought of something, Li Dong's expression suddenly changed. First, his lips wriggled a few times, and a ball of light appeared on his fingertips.
Immediately afterwards, the light ball was bounced forward by him, and then exploded.
Dazzling white light illuminates the front.
Suddenly, an astonishing scene appeared in front of the two of them.
For a moment, Lu Zhong was so shocked that he couldn't even speak.
Because at this moment, he saw that there was actually a sea of bones in this huge space.
