"Crack!"

Gu Yu let out a muffled groan and held his right hand on his waist.

Really shivered.

I became more and more sure that it was right to choose to follow the search and rescue team.

Just say that the coast is safe, then maybe the coast is the most dangerous.

Guyu decided to change the topic and had to stay away from the nerve knife Diping said that he really couldn't accept this thing.

"Neuro Knife, I heard you say that there were moths and plant sheep here before, which proves that this place is already a Yin Ruins. What is this Yin Ruins?"

The nerve knife looked at the black sky, took the cigar in Guyu's hand, took a hard breath, and said:

"We humans have only explored one percent of the ocean world and entered fifty percent of the surface world. If we include the underground part, then human exploration of land is just like that of the ocean, less than one percent.

And just one percent of this, there is a mysterious area where nature is hidden and does not want people to step into. For example, the island under our feet is a cruising island. If it weren't for chance, people wouldn't be able to find it.

In addition to the places where nature hides, there are some mysterious places that are hidden by humans, which are secrets that only those who are on the top of the pyramid know, such as the Antarctic.

All these spaces that are not revealed and hidden by nature and man-made are called Yinxu in the exploration world."

Gu Yu nodded and said:

"In other words, this is a general term in a mysterious area, right?"

The nerve knife pondered for a moment and said:

"It's not entirely true. Yinxu must be a mysterious area, but the mysterious area may not be a Yinxu. For example, Black Bamboo Forest is very mysterious. We have been there, but there is not Yinxu.

To become a yin Ruins, there must be several conditions, such as the oldest, inseparable creatures, such as plants and sheep, and creatures like moths that cannot distinguish animal species, etc..”

Guyu then asked her biggest doubt:

"You said before that this place is already a shady ruin, so it doesn't make sense whether Julie and I go to the beach. What does this mean?"

The nerve knife turned around, turned his back to Guyu, and then pulled the collar to expose the back of his neck.

With the fire, Guyu saw a totem tattoo on the back of the nerve knife.

It looks like a blue-headed black snake coiled, forming a pattern that looks like 8 and is not 8, and it looks more like an hourglass.

Gu Yu didn't understand what the tattoo had to do with Yinxu. Just as he was about to ask, Nervous Knife had already spoken:

"This is not a tattoo, but a disease characteristic."

"sick?"

"Yes, a terrible disease."

"This disease comes from Yinxu?"

"Yes, some people who have entered Yinxu will be infected with this disease, not all. As for the probability ratio, it doesn't make sense. This thing will always be fifty percent."

"What happens if you have this disease?"

"Die, or go crazy, if you have drugs to maintain it, you can delay the onset until seven years later. If you don't have drugs, you will develop the disease in half a year. According to me, eleven of the thirty-nine people who have this disease evaporated from the world and disappeared. It is speculated that they have died in that corner, and twenty-eight people are in a mental hospital."

"Then~~~ Then you still come to Yinxu?"

"What are you afraid of if you already have this disease? And if you don't come, how can you have money to buy medicine? We are very expensive to go for it. Once we are sure that a place may be Yinxu, then only we dare to come."

There was no proud look on the face of the Nervous Knife, although his tone was very proud.

Gu Yuqing couldn't help but touch the back of his neck, and turned around and said:

"Should you please help me see if I have this?"

Nervous Knife smiled:

"It's not that fast! The shortest one will take a month to show up. Don't worry too much. As I said, the chance of this thing is 50%. I pray that you won't get infected with this strange disease in Yinxu."

Gu Yu thought it was true, but it was useless to worry about this thing, so he shook his head and left this matter behind.

"Neuro Knife, were you an explorer before?"

The nerve knife shook his head:

"No, I am an architectural designer, focusing on structural design. Do you know the Rhinek Bridge in the Americas? That's what I'm involved in the design."

Guyu was surprised.

That bridge can be regarded as the pearl of modern architecture history.

"It's hard to imagine, you know, it's really incredible."

The nerve knife wondered:

“Why can’t believe it?”

“Yeah~~~”

Gu Yu pondered for a moment and said:

"You know, structural science requires a lot of knowledge of physics and mechanics, which is extremely rigorous science. How could you accept Diping's words?"

The nerve knife looked at the night sky and seemed to be in deep thought.

"I was arguing with my teacher for a whole class in class because of a topic. At that time, the teacher asked us to design a 3.2-kilometer-long bridge. I was very satisfied with my design, but the teacher failed.

Because when I was designing, I took the data of the earth arc into consideration. According to the size of the earth given by NASA, the earth is circular, so the height difference between the 3.2 kilometers and the bridge should be 4 meters.

At that time, I believed that this gap in arc distance existed objectively and must be included in the design of the bridge structure to ensure the structural stability of the bridge.

For this, I debated with the teacher for half a class. Finally, the teacher saw that he could not convince me, so he told me directly in an authoritative tone that he should not say anything about the arc to him or the ball to him. We just need to remember that all projects are designed and constructed, whether it is a railway or a bridge, and when it does not exist, it is treated as a plane.

Later I worked and found that this is true. When people design and construct, they always build and construct according to the plane of the earth.

It was also from that time that I had doubts about the ground arc. If the ground arc really exists, then when designing the building, large buildings will inevitably collapse due to structural instability, but they did not.

Until one day, I went on a self-driving trip to the grassland. It was a clear autumn day. I sat on the vast grassland and saw a small lighthouse less than ten meters high with a telescope. It was to prevent people from getting lost in the grassland and set it up.

At that moment, I found a way to verify whether the ground arc exists or not, which was the small lighthouse. I drove in a straight line to reach the location of the lighthouse and confirmed that the location of the lighthouse I saw was about 16 kilometers away from the lighthouse.

You can't imagine my shock at that moment. According to the scale of the ground arc given by science, 16 kilometers is enough to allow the ground where the lighthouse I saw was located to fall 20 meters. The lighthouse was only ten meters high. It is logical that it is impossible for me to see it with a telescope sixteen kilometers away, but I saw it and saw it very completely.
