The realm of the four guards was not high, they were all at the sixth level of the Yuan Dan Realm. Lu Chen felt relieved. He wanted to say a few words of pretense, but when he thought about it, it was a bit redundant. Why would he be pretentious with a few dead people?
So, Lu Chen closed the door with his backhand, and without saying a word, he took action with his machete.
After one blow, the four demon heads rolled down and the battle was resolved.
This room was made of special materials and was shockproof and soundproof. It could withstand the power of Lu Chen's sword without making any movement, otherwise it would definitely alarm other demons.
After getting rid of the four guards, Lu Chen had time to look at the room. Just like the previous treasure pavilion, there was an underground door in the center of the room.
Take out the key from the guard's body, open the underground door, and you will see a staircase leading deep underground.
"It's still the same layout. The demon clan really doesn't have anything new."
Lu Chen smiled, then walked over and walked down the stairs.
This staircase was very long, going a thousand feet deep into the ground. Lu Chen walked half a stick of incense before reaching the bottom.
A gate appeared in front of Lu Chen.
The door was locked, and Lu Chen didn't have the key, so he simply kicked it and broke in.
When the door was broken open, a very strong spiritual energy came towards me.
The spiritual energy vein is indeed here!
Lu Chen was overjoyed and walked in, finding a cold cellar inside.
The cellar is made of black zircon, and there are some sunworms, making the whole cellar full of light.
In the center of the cellar, there is a large groove with a radius of a hundred feet and a depth of dozens of feet. The spiritual energy there is even richer.
Lu Chen walked over and took a look. To the east of Guaiguai Long, there was a huge spiritual energy vein slowly moving in the big groove.
That spiritual energy vein was about sixty or seventy feet long and about ten feet in diameter. It was much larger than the spiritual energy vein stolen before, and the spiritual energy it emitted was much richer.
"Haha, I posted it again."
Lu Chen was so happy that he immediately jumped down and stuffed this spiritual energy vein into the Chaos Bead.
The moment the spiritual energy vein disappeared from the spot, countless arrows suddenly shot out from under the groove, shooting at an extremely fast speed.
Lu Chen was shocked and hurriedly activated his true energy to protect his body, and even waved his fingers to chop arrows.
Unexpectedly, those arrows were made of special materials and contained spiritual energy that could kill warriors. Lu Chen's true energy body was penetrated by the arrows, and he was hit by more than ten arrows. If he hadn't split many arrows with a wave of his finger, he would probably have died.
Was shot into a porcupine.
Lu Chen's body could be considered to be strong enough. More than ten arrows were shot on his body, but they were carried down by his strong muscles. They did not penetrate too deeply and the damage was not serious. He only received two arrows on his forehead, which caused extreme pain.
If not, Lu Chen might not be able to survive.
This is a mechanism!
There is a mechanism under the spiritual energy vein. As long as the spiritual energy vein is taken away, the mechanism will be triggered and arrows will be shot out.
Lu Chen took out all the arrows on his body, and then he realized that his head was a little dizzy, and he immediately realized that he was poisoned!
Lu Chen didn't have time to get the Baijie Pill, because the poisonous dragon veins in his body had already shown its power.
Poison Dragon Vein opened its mouth wide and sucked hard, and the toxins in the body were immediately sucked in, and all of them entered Poison Dragon Vein's belly and turned into Poison Dragon Vein's energy.
Lu Chen detoxified the poison on the spot and felt refreshed. Nothing happened.
Since the mechanism was triggered and it was not advisable to stay here for a long time, Lu Chen jumped out of the big groove and prepared to leave.
But I found that I couldn't leave. The door of the cellar that had been kicked to pieces had a dark iron door lowered at some point.
It is estimated that the mechanism was triggered, and the mechanism at the door was also triggered at the same time, sealing the entire cellar.
Outside the Xuantie Gate, countless shouts were heard, and the way out was blocked.
No need to guess, it must have been after the trap was triggered that the guards above knew something was going on below.
However, there was something unusual about those guards. They did not open the black iron door and rushed in. They kept shouting outside.
Lu Chen pushed the Xuan Iron Gate and found that the Xuan Iron Gate had a special structure and was unusually thick.
Don't talk about him, even Tiangang realm warriors can't defeat him!
Since the guards didn't come in, there's probably no way to open the door. It might take the Lord of Demon City to figure out how.
Since we can't get out, we have to find another way out. How can a mere cellar trap people to death?
Lu Chen walked around the cellar and found that it was not only used to store spiritual energy veins, but also a study.
At the end of the cellar, there are several bookshelves with rows of books.
On the side of the bookshelf, there are tables, chairs, coffee tables, etc., and even daily necessities.
Lu Chen casually flipped through a book. The text in it was the same as that of the human race, recording some things in the monster cave.
The books in the Demon Cave are also very valuable to the human race, as they can be used to study the situation of the Demon Clan in the Demon Cave.
Lu Chen waved his hand and stuffed all these books into the space ring. Then he walked to the table and found some documents and the like on it. He checked them and found that they were all useful, so he collected them all.
As for these furniture and other items, they were all belonging to the demon clan. Lu Chen also plucked them and looted them all.
In the end, all that was left was an animal skin painting on the wall.
What is written on that painting is an earthly beast, looking up to the sky and roaring, making an attack gesture, which is wonderful and lifelike.
Lu Chen didn't know what the value of this painting was.
Anyway, to him, it means just one word: Take it!
After taking down the painting, I unexpectedly found a hidden compartment on the wall that required a key to open.
Lu Chen had a fart key, and he directly moved his Yanyang Finger. He clicked multiple fingers in succession before blowing up the wall and taking out the contents of the hidden compartment.
A very long brocade box, about one foot long and one foot wide.
Inside the brocade box is a rolled-up picture scroll.
Opening the scroll, it turned out to be a huge map with four words written in the upper right corner of the map: The Great Map of the Eastern Region.
There is a line of annotation in the lower left corner of the map: Yuanwu calendar, 1,947,523 years, October 10th, general attack!
At first, Lu Chen couldn't understand the meaning of the line of characters. When he saw the entire map clearly, he was shocked.
That map is a complete underground view of the entire Eastern Wasteland, that is, the entire territory of the Monster Clan, displayed in an abbreviated form.
It is marked with all the demon caves developed by the demon clan, as well as the demon cave exits leading to the ground. There are hundreds of small demon caves and dozens of large demon caves.
Only then did Lu Chen understand what the lines in the lower left corner meant.
This year is the Yuanwu calendar, 1,947,523 years!
There is still more than half a year until October 10th.
If I understand correctly, the demon clan will open up all the demon caves on October 10th and launch a general attack on the human race!
If the human race does not take precautions, it may be captured by the monster race in one fell swoop, and the entire Eastern Wasteland will continue to have wars and all life will be in ruins.
This is a top-level military secret. I didn’t expect the Demon City Lord to be so careless and store it here. This is really great news for the human race.
Lu Chen quickly put away this grand map of the Eastern Territory. This was extremely important information. Regarding the safety of the human race, it must be sent to Zhuo Qing.
After receiving such important information, Lu Chen was temporarily happy and left a line of eye-catching evidence on the wall: Lu Chen traveled around again!
Then, it’s time to think about how to get out.
Lu Chen explored every corner of the cellar, even the ceiling, and knocked on it countless times. He was frustrated to find that the entire cellar was built in a layer of black zircon without any flaws.
