A few brave ones successfully passed through the Hundred Poison Formation without antidotes, completely proving their safety.

Hundreds of people immediately flocked to Shimen.

The professional tomb robbers shook their heads and sighed. They had never seen such a massive treasure hunt in a tomb. At first glance, it looked like a big sale in a supermarket.

Some people choose not to go in.

The invisible monster appeared last night, killing and injuring many people. It is so scary outside, and it is understandable that some people who know that they are not strong enough, or who are injured like Mei Qiushui, choose to stay outside and wait and see.

Zhou Lu and his team polished off their tactical light sticks and explored all the way.

The tomb passage is at a forty-five-degree angle, sloping downwards, pitch black, without any light source.

The unknown territory was mysterious and dangerous, and Zhou Lu did not dare to be careless.

He asked the ghost servant Bai Yuemei to come out and help explore the way.

However, they found that Bai Yuemei was hurt as soon as she came out and dropped two levels in a row, so she was quickly sent back to the treasure box world.

This shows that there are great restrictions on spiritual bodies here, and it is best for Sister Shi not to come out.

"It's... incredible!"

Mr. Qi's exclamation attracted everyone's attention.

Zhou Lu, who was walking first, stopped and looked back at Mr. Qi.

Mr. Qi groped the wall of the tomb passage with trembling fingers, then squatted down to check the steps.

He raised his head, with an expression of excitement and surprise, and said in a trembling voice: "While walking along the way, I discovered that the entire tomb passage is made of ten thousand years of black iron ore..."

"His! Wannianxuan Iron Ore?"

Mu Daoxuan took a breath and couldn't help but touch the cave wall with his hands. He placed the tactical light stick close to the cave wall and stared with wide eyes.

Zhou Lu and others also began to take a closer look.

"Is it the kind of black iron that was used to build Yang Guo's 'Xuan Iron Heavy Sword' in the novel? I thought it was fabricated, but why do I know it was ten thousand years old?" Zheng Lindanni didn't know much about this.

"Ten thousand years is just a general term used by the ancients for a long time. The formation of this black iron ore may take tens of millions of years, or it may be hundreds of millions of years, but there is one thing in common. All black iron comes from outside the sky.

Matter that does not belong on earth.”

Mu Jingxue talks eloquently, is a feng shui inheritor of the Mu family, and has extensive research on geology.

"Ah, that means we are standing in a meteor now?"

Zheng Lindanni's almond-shaped eyes widened, this surprise was no small matter.

Zhou Lu was also very surprised.

If we say that black iron ore only appears and flies from the sky, there is no other explanation other than meteors falling to the earth.

People can only occasionally see meteors streaking across the night sky.

And a few of them might be standing in the tomb passage dug by the meteor.

"Yes, when a meteor hits the ground, it is called a meteorite, but not all meteorites contain black iron ore, and the chance of its occurrence is only about one in ten thousand." Mu Jingxue continued to explain, showing her solid knowledge in this area.

"Out of ten thousand meteorites, only one contains black iron ore. Wow...that must be very valuable." Zhou Lu said, touching his chin.

"The current market price of finished black iron is about ten times that of gold."

Mr. Qi is most sensitive to prices, and this is something he is proficient in. He paused, and then said excitedly, "Based on the structure, this meteorite is huge. The Immortal Burial Valley Basin was created by the meteorite, and the Tomb of the Witch King was built in

In this huge meteorite.”

"The ancient tomb built in the black iron meteorite, well, this style is absolutely bad. It's the only one in the world, and even the emperors don't treat it like this."

Zhou Luxian's true energy condensed into his fingers, and he poked a hole into the wall. "The material is very hard. It's not easy to dig out a tomb."

Mu Jingxue shook her head and smiled bitterly: "Zhou Lu, you are amazing. To dig Wannianxuan Iron Mine, you need a special diamond chisel, but you can actually poke holes with your fingers..."

"Presumably, Zhou Tianshi has condensed the innate true energy." Mr. Qi looked at Zhou Lu with eyes full of reverence.

"Yes, Mr. Qi, just call me by my name. We are not outsiders."

Zhou Lu didn't deny it, he smiled, and suddenly his smile became firm, "Many people are following, let's go."

A group of people continued to explore and move forward with excitement.

Walking among meteorites, the black ironite meteorite itself can be called a treasure.

The beauty of the Tomb of the Witch King cannot be described in words.

There are forks in the passage, and you need to stop from time to time to study the correct direction.

About half an hour later.

Zhou Lu pushed open an iron door and his eyes suddenly opened up.

Ahead is a very wide space, like a huge natural cave in karst landform, but this is not natural, it is all artificially dug.

It is such a huge project to carve out a space that can almost accommodate a small city in the giant black iron meteorite. It is much more difficult than building the Egyptian pyramids.

The reason why you can see so far is because there is an unknown luminous object embedded in the ceiling of the cave, like some kind of spar, which shines a stable light blue light, allowing the naked eye to roughly see the outline of the underground space.

The crystals on the ceiling of the cave are arranged in an unknown pattern like a constellation according to a certain mysterious order.

The position where Zhou Lu and others were standing was in the middle of the cave wall of this space.

From the top, it is visually estimated to be a hundred meters high.

There is also a distance of twenty or thirty meters from the bottom of the ground, connected by a ladder with a steep slope.

Everyone was shocked when they saw this scene.

Zhou Lu didn't pay much attention to the unknown pattern. He focused on the bottom building and the group of ghosts.

From the architectural point of view, it is an ancient and magnificent palace city, which has similarities with the palaces of the pre-Qin period of China. It is very different from the ancient tombs described in movies such as "Tomb Raider" and "Ghost Blowing Lamp".

It's very lively here, and there are many ghosts wandering around in the underground palace.

This is Zhou Lu's favorite scene.

It’s time to upgrade the ghost slayer.

Wait...are they all level one wild ghosts?

After being promoted to a coquettish master, you can get almost no experience by killing level one wild ghosts.

All the ghosts here are wiped out, and the total experience is not as good as one ghost soldier.

There's no need to get started.

Zhou Lu was a little disappointed, but he wasn't surprised after thinking about it.

Bai Yuemei will drop two levels within a few seconds after she comes out.

There is a certain restriction here that allows all spirits to only exist at the lowest level. Even if the Ghost Emperor comes in, he may soon be reduced to a first-level wild ghost.

"Everyone open your eyes, there will be a surprise."

Zhou Lu said to the team members with a smile.

Several people obeyed the instructions and took out cow's tears and wiped them on their eyelids.

"Ah, so many ghosts!"

Mu Lixue couldn't help but hugged Zhou Lu's arm.

The subconscious reaction showed that her sense of security came from Zhou Lu.

"There must be tens of thousands. Qianhuailing's Hundred Ghosts Walking at Night is far worse than this." Murong Jingxue could hear the tension in her voice. She also moved her body towards Zhou Lu, but did not reach out to touch him.

Zheng Lindanni was so frightened that she trembled: "This, this is a shock, not a surprise. Zhou Lu, you are so bad..."

Zhou Lu's arm felt the soft touch in front of Mu Lixue's body. His heart trembled, and he laughed and said:

"Don't worry, these ghosts are harmless to humans, and there aren't even any serious ghosts."
