The stone door that led from the front hall to the Hall of the Dead actually fell down quickly, sealing off the entire Hall of the Dead.
Cao Xiaoying rushed to the side of the stone door and hammered it a few times, but found that the stone door did not move at all.
Xu Nuo frowned.
Many changes had taken place in this world's Dragon Ridge Maze Secret Realm.
The mechanisms were also more complicated.
It was really difficult to deal with it.
Xu Nuo quickly glanced at the Hall of the Dead and pointed at the high platform beside the entrance.
"Everyone, stand here. This place is a little higher.”
After Cao Xiaoying came up, she asked in a sobbing voice," Teacher Tang, Professor Hao, are we going to die? I remember that mercury vapor is poisonous too, and I don't want to become as terrible as Lurin.”
Tang Xue wanted to comfort Cao Xiaoying, but she did not say anything.
The entire chamber was sealed, and the mercury vapor could not escape. If it was not submerged by the mercury for a long time, it would be poisoned to death.
It had only been a minute or two since Lu Ning had triggered the mechanism, and they were already feeling a little dizzy.
It was obvious that the toxicity of the mercury vapor had appeared.
Xu Nuo quickly exchanged for a few Red Dowry Wonder Pills from the system space.
A Red Casket Wonder Pill cost 10 experience points.
However, the effect was also very good.
It could effectively remove the poisonous gas of the zombies in the tomb, all kinds of toxins in the air, and also alleviate mercury vapor poisoning. At the same time, it could also help people maintain their condition.
Xu Nuo didn't have time to explain and directly let the few Ran shout this thing in their mouths.
Xu Nuo also had one in her mouth.
Then, he lay on the wall of the tomb and began to hit the wall of the tomb with the shovel.
A moment later, the voice spread throughout the entire tomb and returned to Xu Nuo's ears.
Xu Nuo suddenly had an understanding of the internal structure of the entire tomb, and she could not help but feel a chill from the bottom of her heart.
The traps in Li Chunfeng's tomb were really impressive.
If Xu Nuo hadn't known some of the arrangements beforehand and had the ability to listen to the thunder and identify the tomb, the entire expedition team would definitely have died in the Hall of the Dead.
As expected of an A-grade secret realm.
However, Xu Nuo was already confident.
"Old Lei!" Xu Nuo shouted.
Lei Zhengyi looked anxious.
He immediately responded after hearing Xu Nuo's words.
"Did you bring that metal brush?”
Old Lei immediately took out a brush from his backpack.
"See that hole? Put the brush in!"
Xu Nuo pointed to Old Lei's side.
Ray Zhengyi swept his flashlight across the area and found a hole as thick as an egg at the height of half a person.
Old Lei was also shocked.
However, he still quickly inserted the metal brush into the hole.
Then, a strange sound of a mechanism turning could be heard.
Many grooves appeared on the ground.
The mercury that was originally spreading on the ground actually flowed up along these grooves, from the walls of the Hall of the Dead to the dome of the tomb.
A moment later, silver light flashed on the dome.
The gemstone and the mercury shone together, causing the entire Hall of the Dead to be shrouded in a layer of blurry light.
The mercury on the ground had actually disappeared.
Tang Xue's eyes widened.
Professor Hao muttered," It's too unbelievable, too unbelievable.”
Everything that was happening in front of him had completely exceeded the imagination of ordinary people.
The density of mercury was extremely high.
To rise from the ground along the groove, it was not something that could be done by relying on air pressure.
There must be some kind of mysterious mechanism operating behind the scenes.
At the same time, the starry sky map on the dome was completely revealed.
Xu Nuo took a look and immediately knew that the starry sky map of the dome contained a lot of information.
Some of the stars hadn't even seen Xu Nuo, who had mastered the Falling Star Acupuncture.
Planet Yin?
Xu Nuo did not stand on ceremony. She focused on the starry sky pattern on the dome and tried her best to remember it.
Soon, the system notification sounded.
"Congratulations to the host for observing the Yisi Astrology. You have received 100 experience points.”
"Congratulations to the host for obtaining the divine power Li Chunfeng's Yisi Astrology.”
Xu Nuo's eyes lit up.
Li Chunfeng was a master of mathematics in the Tang Dynasty, as famous as Yuan Tiangang.
Not only was he the first person to annotate the Zhoubi Suanjing, but he was also the person who wrote the first systematic astrology book in the history of the country.
Of course, Li Chunfeng's most famous work was still the " Pushing Back Map " that he collaborated with Yuan Tiangang.
Yi Si Astrology was related to the Falling Star Acupuncture Point. It could be verified with the Heavenly Star Feng Shui to increase the accuracy of the Falling Star Acupuncture Point.
Moreover, astrology could also be used for divination.
This was also the origin of the legendary night observation and divination.
He did not expect to have such an unexpected harvest in this ancient tomb mystic realm.
This was not the end.
Soon, the golden Phoebe Wood coffin on the stone platform in the middle of the Hall of the Dead was completely opened like a lotus flower.
The eight-treasure screw coffin was revealed.
This was the real Li Chunfeng's coffin.
At this moment, the mercury on the floor of the chamber had already subsided, and there was no danger.
Everyone quickly moved forward, afraid that there were other mechanisms.
They stopped in front of Li Chunfeng's coffin.
Lu Ning's body was still beside him. No one dared to open the coffin now.
It was really not easy to open a coffin in an A-grade secret realm.
There were pits everywhere, and who knew which one of them would fall into the pit.
Xu Nuo also knew how powerful it was.
Li Chunfeng was an expert in the art of mechanics. He made full use of the hidden spring's eye and used water as the power to set up many mechanisms.
These traps didn't seem to be traps that used bows, fire, and poisonous smoke. As time passed, they might completely lose their effectiveness after a few hundred years.
As long as the mechanism made of flowing water and stones was not exhausted, it could still function even after a thousand years.
This was Li Chunfeng's strength.
Xu Nuo walked to Li Chunfeng's coffin and immediately used the handle of the shovel to gently knock on the coffin.
Soon, the sound and vibration spread throughout the entire coffin.
There was nothing wrong with the coffin.
Xu Nuo quickly took out the Yin Probing Claw, the black scroll, and the stumbling rope from her backpack.
Tang Xue and Professor Hao were dumbfounded.
Xu Nuo had never seen any of these tools before.
What was even more ridiculous was that Xu Nuo actually took out a black donkey hoof from her backpack.
This was what Old Lei recognized after looking at it for a long time.
"Everyone, don't misunderstand. I can explain this. This thing is just a protective charm to me…"
Xu Nuo began to bluff without any psychological pressure.
Then, he picked up the Yin Probing Claw and prepared to open the coffin.
