I don't know how long it took, but the car stopped.

The doors slowly opened.

What catches your eye is still a patch of yellow sand.

I thought I was out of the desert, but I didn't expect to be in the desert.

At this moment, this endless piece of yellow sand makes me feel palpitations.

"We're here." The old man said.

I looked around suspiciously, and there was nothing special except sand.

The old man seemed to see my doubts.

He pulled out a card-like object and twisted it out of thin air.

Something strange happened, a door appeared out of thin air, as if a hole had suddenly opened in the air.

"Come in." The old man shouted at me, who was still in a daze.

I hurriedly followed in his footsteps and walked in.

After passing through a winding passageway, it suddenly became clear that a huge base could be built under the desert.

People come and go in the base.

"This is our home." The old man said as he walked.

"You ...... Who the hell is it? ”

"Just like you, fugitives." The old man looked at me with a majestic and solemn look in his eyes.

"What?! You guys...... Escaped from that place too? "I was even more confused.

The old man did not answer. Walked straight into one of the most conspicuous domed houses on the base.

"This desert is not that simple, come in and sit."

As soon as he finished speaking, three burly men came out of the back room. He said to the old man, "Chief, you are back." ”

"Is this the 'key' you say?" They looked me up and down, and to be honest, I had never been looked at like this by a strong man, let alone a few big men who were five big and three thick.

They looked at me a little frightened, and in order to relieve the embarrassment, I quickly found a chair and sat down, and looked directly at the old man, who was called the chief, hoping that he would tell me something.

"Do you think it's that easy to escape from that place?" The old man said to me, "That place is called the 'Last Days' Prison. ”

"Apocalyptic prison? Do you mean where I used to work? ”

"Everyone here has escaped from the prison of the end times, I am one of the first people to escape, I am the commander here, you can call me the leader of the Thunder Eagle."

"Wait, Thunderhawk Leader, did you mean that I didn't escape on my own?"

"It's hard for you to escape from the mechanized troops, but it's because we used a device that we've been researching for more than 10 years to jam their radar search signals, so you can escape."

"Then how did you escape back then, Thunderhawk Leader? Back then, you hadn't developed a machine that could jam radar search signals, did you? I asked curiously.

Those of you certainly didn't expect me to be a curious baby.

Such a question does feel a bit of a trick.

Thankfully, they don't discriminate against keyboard warriors.

"The leader is not like us." One of the big men said.

"It doesn't look like any different from us!" I looked at the old man.

"I don't belong here, I'm from the higher worlds." The old man said calmly again, "I understand certain loopholes. ”

"That'...... Then why are you locked up in a post-apocalyptic prison? "I was so surprised that my jaw was about to drop to the ground, this was the first time I had seen people from the high world, and I was glad that they didn't have anything special, they all had two eyes, a nose and a mouth, I thought they might have little devil tails.

"Let's talk about this desert, it's about whether or not you can get to the Red River." It seems that the old man did not want to answer my question.

"Okay, tell me a little bit about this desert, and why you said I was the Key?"

"You are the key to our ability to break through the Dimensional Barrier!"

"What is a dimensional barrier?"

"The wall that connects the upper world and the lower world! It is also the invisible border of this desert, as long as there is this barrier, this desert is endless, and it can never be walked out. ”

"Why me?"

"Your signals are different from others."

"I don't understand."

"You don't need to understand now, I'll tell you what to do, I must go to the surface world!"

"The surface world?" I was confused.

"Yes, the surface world, I originally thought that this world only had the upper world and the lower world, until more than ten years ago, a friend of mine in the upper world told me a secret, this world is not only the upper world and the lower world, above the upper world, there may be a surface world! When I learned this secret, I was looking for a way to get to the outer world, which saw me as a criminal trying to break the rules and order, and imprisoned me in the post-apocalyptic prison of the lower world. ”

"I see, did you find anything?"

"Over the years, I have been researching ways to break the "dimensional barrier", so far, I only know how to go from the bottom world to the high world, and as for the surface world, there is still no progress."

"Why are you so obsessed with finding the surface world?"

"I want to find out."

"Answer?"

"Yes, answer."

"Well, while I don't know the answer, I just want to know what you want me to do?"

"Tomorrow, you go to the "Border Lands" with us, if you want to go there, you must pass through the area where the Robo-Men Force is stationed, there are more than 500 people in our base, we will desperately escort you to the Border Lands, as long as you go there, the dimensional barrier will force a crack to open because of your abnormal signal."

"Why should I take such a big risk to help you?"

"If you want to go to the Red River, you have to go to the high-level world, and now you have no choice."

"Okay, I'll join."

"Tomorrow will be our last battle!" , The leader of the Thunder Eagle turned back to the three big men and said, "Brothers, notify me!" Get all the desert armored speeders and weapons we've built over the years, and may we all make it to the higher worlds alive tomorrow! ”

"Yes! Chief, we must get out alive! ”

After speaking, the three big men went out. Only me and the old man were left.

"Leader of the Thunderhawks, you ...... Have you ever been to the Red River? I asked.

"I believe the way to the surface world is hidden there."

"Have you been?" I repeated.

"Fall into the Red River, there is also a dimensional barrier there."

"What happens if I go there?"

"I don't know, it's called a holy place, and only fanatics go there. Tomorrow, if we can make it to the higher world alive, my next plan is to go to the Red River with you, and maybe your "key" can find a way to break through the dimensional barrier. ”

"Actually, I went there to find someone."

"Looking for whom?"

"A woman I love."
