It doesn't matter if human beings evolved from apes or were created by "gods".

When human beings came into this world, they were full of fear in the face of this unpredictable world.

So some of them began to think, trying to find the only eternal truth and law in this world.

These thinkers, known as witches in ancient tribes, were scientists in the human community at that time.

They use everything they can perceive to find this unchanging truth, the transformation of the sun, moon and stars, the change of the four seasons, the change of sound and the severity of sounds, and the biochemistry of plants, trees, birds and beasts......

As a result, the world has a lunar calendar, a solar calendar, a lunar calendar, a rhythm, and a materia medica......

However, these are not eternal truths after all.

If they don't forget, there will be an echo, and finally they found it.

2,600 years ago, in the Spring and Autumn Period, Lao Tzu Li Er, he felt that the eternal truth of this world is "the movement of the opposite, the use of the weak Tao".

1,300 years ago, the illiterate Sixth Patriarch Huineng, who founded Mahayana Buddhism, did not know how to read but made the Buddha really speak Mandarin, saying that the eternal and unchanging truth of this world is "dependent arising emptiness".

A hundred years ago to the present, a group of cultivators of quantum mechanics finally discovered that the most basic material quantum in this world is the existence of transformation between wave particles with the interference of consciousness, which is the rule of origin.

On the contrary, whether it is the movement of the Tao or the emptiness of dependent origination, the same is true of wave-particle duality, and what they tell the world is nothing more than one sentence:

"In this world, the eternal and unchanging truth is - change."

The only constant in this world is "change", relative change.

The opposite side of cold is warm, the opposite side of high is low, the opposite side of light is dark, and the opposite side of real is false.

Qin Shuying shouted out the sentence "Everything is relative", which is a truth that almost every Chinese person understands, but it contains thousands of years of human efforts.

"But, how so? I can be sure that I am awake and that all this is not an illusion! ”

Qin Shuying said in disbelief.

Yun Qianfeng shook his head and said:

"What you see when you're awake is not necessarily the truth, and the time and the constant picture of the watch tell us that what we see in front of us must be fake. Maybe it's a mirage-like optical hoax, or maybe it's something here that changes the reception band of our brains, and I'm leaning more towards the latter because they use ayahuasca. ”

Qin Shuying understood what Yun Qianfeng meant, and immediately said:

"What you mean is that there's something in this environment that changes the frequency bands that our brains receive, so much so that we see the illusion of hallucinations in a waking state. Therefore, Jiang Yulin and they used ayahuasca to change the reception band of the human brain, and did addition and subtraction with the current changed brain reception band in order to see the truth. ”

Yun Qianfeng nodded and said:

"Yes, that's it! Therefore, to pass this hurdle, we must be people with the same physique as me to do it, because we can still stay awake under the effect of the drug and see the real golden city clearly. ”

Jiang Roujia looked at the glass bottle and said with a bitter face:

"However, we don't have ayahuasca. Will the poison powder on the wings of those flying heads be effective? ”

Qin Shuying shook his head and said:

"Those poisonous powders are completely different from the concept of ayahuasca, and that poisonous powder has no effect on Yun Qianfeng's physique."

The two women's faces were full of helplessness, and they unlocked the code of the key, but they did not have the necessary key.

Unexpectedly, Yun Qianfeng shook his head and said:

"I have a way, but it's a little dangerous, it's up to you to save my life, Miss Qin."

"Huh?"

"What's the solution?"

"Don't do it when it's dangerous!"

Yun Qianfeng smiled bitterly:

"If we don't, we'll be trapped here."

After speaking, he took off his coat and undershirt, and then asked Qin Shuying to take off her undershirt or underwear.

Qin Shuying didn't know why, but in order to avoid going naked, she took off her underwear behind her back.

In this way, it is covered with a base layer, even if you need to take off your coat, it will not be too embarrassing.

Yun Qianfeng looked at the two women and said:

"Tie my hands behind my back with my coat."

When the two women had done so, he gave another order:

"Strangled my nose with my base shirt and made sure it didn't breathe."

After getting it done, he looked at Qin Shuying and said in a sullen voice:

"Next, you have to stuff your underwear into my mouth, you have to plug my throat, and then I will go into a state of suffocation, you have to keep an eye on my pulse, pull out the clothes in my mouth before the limit is reached, and my life is in your hands."

Qin Shuying shook his head and said:

"It's not going to work, it's too dangerous, I can't be sure when the limit is, I can't do it."

Yun Qianfeng smiled bitterly:

"There's no way, I can only do this, I knew when I was drowning in a state of suffocation, that kind of thing in my body would soar, let me see hallucinations, this is the only way we can, or that sentence, my life is in your hands, gag!"

Qin Shuying took a big breath to stabilize his mind, and then with tears in his eyes, he stuffed his underwear deep into Yun Qianfeng's mouth, straight to his throat.

As time passed, Yun Qianfeng's face began to turn red, and after a while, he began to struggle and tremble, the blood vessels in his forehead bulged high, and his originally black and white eyes began to crawl with bloodshot like spider webs.

Seeing Yun Qianfeng constantly raising his neck high and his body bouncing one by one, Qin Shuying's hand immediately left Yun Qianfeng's pulse, and he pulled out the underwear in Yun Qianfeng's mouth, and he could see that the underwear close to his throat was already stained with blood.

"Hah Hah... Hahh......"

Yun Qianfeng gasped heavily, and after a few sips, he said in a hoarse voice:

"It's not enough, it's blocked!"

Jiang Roujia sobbed and stuffed her underwear into Yun Qianfeng's mouth again.

The pain of suffocation tortured Yun Qianfeng's body and soul again, he began to feel a little dizzy, and his face began to swell, as if a drowning person had swollen his face, the only difference was that his face was purple-red.

The second time he was near-dead, Yun Qianfeng only gasped for two breaths, and shouted:

"Plug it!"

Jiang Roujia snorted the snot that flowed out, gritted her teeth and stuffed her underwear into Yun Qianfeng's mouth again, straight to the depths.

The whites of Yun Qianfeng's eyes had completely turned red, like the eyes of a devil in the middle of the night.

The struggle and writhing of his body was no longer human, more like a zombie's stiffness.

The two women had already cried into tears, and they knew that if Yun Qianfeng did not die like this, he would also cause irreversible damage to the brain due to lack of oxygen, and the consequences would be unpredictable, which was too dangerous.

Just shouted in Qin Shuying's mouth:

"Then let's die here together!"

As he spoke, he pulled off the underwear in Yun Qianfeng's mouth.

She couldn't watch Yun Qianfeng suffer like this.

At this moment, Yun Qianfeng sat up straight on his knees, his eyes seemed to be looking into the distance, and his face showed incredulity and surprise.

Jiang Roujia and Qin Shuying looked at Yun Qianfeng's red eyes, and saw a little golden light in his eyes, it was not that his eyes would glow, but that he saw something golden.

The two girls turned their heads and followed Yun Qianfeng's gaze, but there were only dark stone walls and messy rubble.

"Golden, where?"
