"Familiar?"

Professor Chan then spoke, and the person who asked me was me.

The reason why Professor Chen asked me this question was precisely because I stared at his bare shoulders in surprise at this time.

On Professor Chen's left shoulder, near the collarbone, I could clearly see three dark red bright spots on it.

The dark red glow emitted by the three bright spots seemed to emanate from under Professor Chen's skin.

Moreover, between the three bright spots, you can faintly see the thin lines that are also glowing with dark red light connecting them, and finally these three bright spots, along with those slightly shallower straight lines, form a regular triangular shape on Professor Chen's shoulder.

"Dad! You"

The vision on Professor Chen's shoulder was obviously also seen in Bai Yi's eyes, and I have to say that this scene in front of him was really like a dark red flame burning under Professor Chen's skin.

It's a very uncomfortable feeling.

After Bai Yi saw the vision on Professor Chen's shoulder, she couldn't help but let out an exclamation from her mouth, but soon she covered her subconsciously open mouth tightly.

Professor Chen's eyes glanced at Bai Yi's face with a look of surprise, and then he asked me again.

"Does this look familiar?"

As he spoke, Professor Chen also stretched out his hand and pointed to the dark red triangle on his left shoulder.

I know very well why Professor Chan would ask me this.

Because, on my left shoulder, in the same position, there are exactly three dark red birthmarks the size of soybeans.

Since I was a child, these three birthmarks did not make me feel anything strange, but after seeing the vision on Professor Chen's shoulder at this time, I didn't know if it was my own psychological reason, and I suddenly felt a little uncomfortable on my left shoulder.

As if seeing through the reason for my sudden strange face, Professor Chen said to me slowly again.

"You should see for yourself"

After hearing what Professor Chen said, I hesitated for a moment, and finally raised my hand and pulled my collar open.

As I glared over my left shoulder, my eyes froze.

I saw that the originally dark red birthmarks on my left shoulder also began to glow from under the skin at this time, and between the three birthmarks, there was also a faint shallow straight line, although it was not obvious to see, but a vague triangular shape could be seen.

Seeing this, I was only stunned for a moment, and I immediately raised my eyes to look at Professor Chen, who was standing not far away.

Although I didn't speak, the anxiety and panic in my eyes were already clearly conveying a message to Professor Chen.

"What the hell is going on?"

"You and I are the same kind of people"

Professor Chen fully understood the meaning in my eyes, and after a light sigh, he spoke slowly again.

"Now I can tell you for sure that what you just said is true."

Speaking of this, Professor Chen looked up at the darkness above his head, closed his eyes and took a deep breath before continuing.

"As you think, this is indeed the place where we once lived."

After a pause, ignoring the growing incomprehension on Bai Yi's and my faces, Professor Chen continued.

"You and I are both descendants of the previous generation of humans, and this thing is the code that was left in our genes in the first place."

As he spoke, Professor Chen raised his hand again and pointed to the dark red triangle above his left shoulder.

I can understand what Professor Chen is saying now.

What Professor Chen meant was to prove the correctness of the previous discussion between me and Bai Yi, that this is indeed the place where the previous generation of intelligent life on earth lived, and according to Professor Chen, he also affirmed that I and he are also the descendants of the previous generation of intelligent life.

"What does this password do?"

After knowing that this was a big secret to me, my head was about to explode in an instant, and I never thought that such a thing like me would have such a special identity.

Trying to suppress the dizziness in my head, I asked Professor Chen with a trembling voice.

"Passwords allow us to find each other's kind, and at the same time, they can also awaken some subconscious memories. For example, "

Professor Chen paused again and continued.

"You often have strange dreams about what you do, and those are not just dreams, but they really happen."

Indeed, as Professor Chan said, since I started this strange experience, I have really experienced some strange dreams that are both fantasy and real, and Professor Chan has explained clearly why I have these dreams.

"What do you mean, my parents are also descendants of those people"

In my heart, I still can't accept my identity as a descendant of the intelligent life that lived on the earth in the previous generation, so I have to replace it with "those people".

After hearing this, Professor Chen shook his head before replying.

"They're not the only ones"

Professor Chen's answer suddenly made me even more puzzled.

"What do you mean?"

I wrinkled my eyebrows and couldn't help but ask Professor Chen.

"Do you know that the ghost is on the upper body?"

Professor Chen's rhetorical question made my brows tighten even more, and Bai Yi on the side was the same, perhaps because he couldn't accept Professor Chen's change for a while, Bai Yi at this time still covered his lips tightly with his hands, staring at his eyes and unable to say a word.

Professor Chan didn't wait for me to answer, but continued.

"Actually, you and I are just ghosts"

As he spoke, Professor Chen lowered his head and shook it.

"That terrible catastrophe completely ruined everything, really ruined everything we lived, the people we loved and loved us, the barrenness, loneliness, fear, this is the only one who survived, and what became of those who survived?"

Speaking of this, Professor Chen not only smiled bitterly.

"We have no body, we can't see anything, we can't hear anything, we can only wander around in solitude like a breeze, until we find a suitable host at the end of the day."

Professor Chen's explanation made my throat move and swallow a mouthful of saliva with difficulty.

What he said sounded really perfect to explain the "ghost body" he mentioned just now.

According to his meaning, after another terrible catastrophe, everything is destroyed, and all that survives is some "human" with formless matter, just like a person dies and has an out-of-body soul

I don't know how many people have survived in this way

And most importantly, what kind of terrible disaster happened in the first place
