There is a lake near Concord City, Massachusetts called Walden.

Although Walden Lake has the name of a lake, it is actually a large pond located on the edge of a green mountain, about the same size as an ordinary artificial lake.

It is famous because a famous philosopher lived here for several years.

Although this great philosopher has long since gone by crane immortal, the fame of this lake has long been spread with this great philosopher, and it is said that when the philosopher's fame was at its highest, it was also crowded with tourists.

Nowadays, Walden's reputation is gone, but time is the easiest thing to kill everything, except for the occasional out-of-town tourists, it is quite sparsely populated.

On the west side of the lake is a three-story building with blue walls and red tiles, in the style of an ordinary residential building, and the courtyard in front of it is fenced.

From the outside, this building is very ordinary, only when you get closer, you can know that the courtyard walls and doors of this building are installed with very modern monitoring equipment, and strangers cannot enter at all without the invitation of the owner.

Kong Meiren's plane landed on the lawn in front of the courtyard, and after she got off the plane, she waved to the pilot, signaling him to leave first.

"Senior sister, is this the famous Walden? ”

After the scarlet tiger got off the plane, he circled around the lake at a low altitude, and then flew back, landed on Kong Meiren's shoulder, and pouted.

"What should Walden look like in your mind?" Kong Meiren glanced at it faintly.

"I thought...... Yo, Professor Yang is out. ”

Scarlet Tiger was about to express his unique opinion unashamedly, but when he rolled his eyes, he saw the door of the courtyard of the opposite building open, and Yang Qing, who was wearing a white coat, walked out of it.

"You've got a strong desire to survive. Kong Meiren glanced at it, turned her head to look over, and sure enough, she saw Yang Qingzheng walking towards her quickly.

"You're here to get it quickly, yo, you have a cat with you in addition to the little scarlet tiger. Yang Qing walked up to Kong Meiren, a gentle smile appeared on her not very outstanding face, and her gaze swept over the scarlet tiger and stopped at Feng Tang.

It's really a guy who likes the new and hates the old, and when he sees the new, he treats the old person as nothing, and the scarlet tiger who feels neglected silently slanders in his heart.

"What, you think I'm ignoring you?" Yang Qing seemed to be able to read minds, and as soon as the scarlet tiger's belly was slandered, he turned his eyes to look at it.

"Professor Yang, do you want to scare others so much? Kong Meiren, didn't you say that the secret of that bone has been studied, take us in quickly. ”

The scarlet tiger was taken aback, and quietly shrank to the neck socket of Kong Meiren, after it became a bird, it was not afraid of heaven and earth, it was a little bit of Yang Qing, a guy whose EQ and IQ were frighteningly high, and it was incomprehensible.

"Okay, let's go in first, it's also strange, this guy is not afraid of anyone, but seeing you is like a cat meeting a mouse." Kong Meiren looked a little funny.

"Well, maybe it has something to do with my profession, animals are more sensitive, and the smarter they are, the more so, and that cat is also very wary of me. Yang Qing pointed to Feng Tang, who had not been angry, and said with a smile.

"Yo, that's really the case, then why is my Huaiqing not afraid of you?" Kong Meiren turned her head to look at Feng Tang, who had a serious face and was much more cautious than usual, and raised her eyebrows slightly.

"Huaiqing is actually very wary of me, but it is more familiar with me, and this sense of precaution is relatively necessary to talk about, and if you don't pay attention, you can't detect it. Yang Qing spoke as he led them into the house.

The first floor of Yang Qing's house is the living room, after entering the living room, Yang Qing asked them if they wanted to drink water, Kong Meiren, Scarlet Tiger and Feng Tang all shook their heads, seeing that they didn't drink water, Yang Qing took them to the second floor.

Coming to the room on the left hand side of the second floor, Yang Qing pushed the door and entered, this room is fully enclosed, and the windows are made of military protective glass.

That is, once the window is closed, no sound from the outside can be heard, and similarly, no sound can be transmitted from the inside.

The curtains on the window were also drawn, and on a square table by the window, with some kind of instrument that the Scarlet Tiger did not recognize, placed the gray-white skeleton that the Scarlet Tiger had brought from the Yellow Mountain.

"What the hell is its secret?" asked Kong Meiren as she walked over to the table, her eyes falling on the skeleton.

"There is some kind of mysterious energy on this skeleton that ordinary people can't detect, right?" Yang Qing asked without answering.

"Yes, faintly, but it does exist. Kong Meiren nodded.

"Based on my observations and continuous experiments for more than two months, I can basically draw a conclusion that it does not belong to the product of our civilization. Yang Qingdao.

"In other words, according to it, it can be judged that there is indeed more than our generation of civilization on our earth?" Kong Meiren's eyes flashed when she heard this.

The eyes of the scarlet tiger and the phoenix orange also lit up, and anyone who heard such words would have infinite curiosity in their hearts, and they were no exception.

"Not bad. Yang Qing nodded.

"Is it possible to tell which civilization it came from?" asked Confucius.

"I can't judge this for the time being, if you want to find out where they came from, you can probe from the place where they appeared, but it is only possible to find the root cause, and it is more likely that nothing can be found. ”

"With so many outstanding scientists in the world, it is impossible that no one has doubts about those products left over from ancient times, but obviously not belonging to those eras, but after so many, no one can find the exact source and evidence of prehistoric civilization. ”

"There are only two possibilities for a civilization that once existed, but in the end it disappeared without a trace, one is that this civilization has completely disappeared, and the other is that they have left the earth. Yang Qingdao.

"I see, thank you, whether you can find it or not, you have done me a great favor. Kong Meiren's eyes showed sincere gratitude.

With an identity like Yang Qing, getting such a thing, and determining that it does not belong to the civilization of this era, it stands to reason that he should report it to the state, but he didn't do anything, it was like doing an inconsequential little thing for himself.

"You don't have to thank me, in fact, if I had to choose, I wouldn't tell you that. Yang Qing's gaze was a little complicated.

"I know, but you also know that these are things that I have been desperately pursuing for nearly a decade, and if I do give my life for them, I have no regrets. Kong Meiren smiled slightly, reached out and gently patted him on the shoulder.

"Let's go, go downstairs, we're going to make you a whole fish feast today. Yang Qing looked at her quietly for a while, then withdrew his gaze and walked out.

Kong Meiren followed him, and when he was about to go out, the scarlet tiger lying on Kong Meiren's shoulder found that Feng Tang was still squatting in place in a daze, and couldn't help but open his mouth and called: "Feng Tang, what are you in a daze, hurry up and follow." ”
