Song Zehan expected that Ruan Shiyan would ask this question first.

Almost as soon as her voice fell, she nodded before she spoke.

"Yes."

Song Zehan's tone was serious, and his voice was firm.

Ruan Shiyan was stunned.

Is there really one?

"Then why don't I have any new wounds? And I don't look like a person who has undergone major surgery! ”

"Even if I may have slept for a long time and my state has recovered, the wound can't go away."

Song Zehan slowly sorted out his shirt, and looked at Ruan Shiyan's eyes with a little more complicated.

The eyes met, and after a while, they said euphemistically.

"Yan Yan, do you believe that there really is a time machine in this world?"

"Time machine?" The twist of this topic was too big, and it suddenly shocked Ruan Shiyan, "That's it...... The kind of Doraemon that? ”

"Well, something like that." Song Zehan nodded his head.

Ruan Shiyan blinked, and after a while, she gave her most honest answer.

"I ...... I didn't believe it before, but when you asked, I kind of thought there should be a story behind it. ”

Song Zehan's well-defined fingers swiped the tip of Ruan Shiyan's nose, and seeing that her acceptance should be relatively high, the complexity under her eyes dissipated a little.

"Human civilization has been developing, and science and technology have been advancing. Some problems that are difficult to solve at the moment will be very easy in 50 or 100 years. ”

Ruan Shiyan nodded.

"I understand this, just like the ancient people wanted to deliver a message to whom, in addition to coming to the door in person, they could only pass through oral messages or letters, not to mention the trouble, and it was very time-consuming, but now you only need to move your fingers."

Song Zehan let out a "hmm" and continued along the lines of Ruan Shiyan's explanation.

"And the reason why we know that the way ancient people transmitted news was through some archaeological research, so have you ever thought that we are actually the object of study by future people?"

Time Machine ......

Problems of today can be easily solved in the future......

People of the Future......

Ruan Shiyan quickly concatenate this information and came up with a guess that she didn't know how to believe.

It was precisely because this guess was so unbelievable that she didn't answer, just quietly waiting for Song Zehan's explanation.

After all, it must not be easy to let Song Zehan pave so many answers.

"Actually, I came into contact with people who didn't exist in this era, and to them, we were the ancients in their eyes."

"At first, they invited me to conduct some experiments and obtain some data, so as to achieve the purpose of understanding the people of this era."

"But I refused."

Song Zehan blinked slowly, and when he spoke again, there was a hint of memory in his voice.

"I didn't believe it when I first met, but it didn't take long for you to have an accident. I had no choice but to turn to them. ”

Hearing this, Ruan Shiyan couldn't hold back and interrupted Song Zehan, "So I came back from the dead...... Did they do it?! ”

"Yes." Song Zehan nodded and continued to explain: "The cause of your death is related to the heart, and in their way, they gave you a special heart, and they can also repair the brain damaged due to ischemia to the greatest extent. ”

"But there is only one point, in exchange, I can't talk to you directly, as long as I say it, and being found by them will make your heart stop beating instantly."

"Although it will recover immediately, the speed of the beating is very slow, and the process from stopping to full recovery is about two hours."
