At the southern foot of Yunlong Mountain in northern Hebei, there is a small town called Kaiping in the depths of the lofty mountains, the town is very small, and it is also very mysterious, there are almost few permanent residents, and two secret units are hidden in the mountains and forests, although it is not a military control area, but it is heavily guarded.

A winding mountain road winds and disappears in the middle of the cascading mountains, the only way to the outside world, and a jeep slowly moves along the mountain road, although it has slowed down to thirty yards, but it is still bumpy and unbearable, as if the next bend is about to fall apart.

Li Tianzhen and Old Man Dong didn't feel anything, but it took too long to be anxious, if it weren't for the formalities and procedures, they wouldn't need to take a car, they would have arrived at their destination a long time ago, but there was no way, the middle-aged man who accompanied them was miserable, he had walked this road countless times, and every time he was guilty, but he never seemed to be able to adapt to it.

One of the units they were going to was actually a sanatorium similar to a quarantine area, where several special people lived, and it was one of them that Li Tianji was going to visit this time, and he was also one of the two old men who were rescued twenty years ago, and who was secretly protected here for various reasons.

Li Tianji pays special attention to the word protection, indicating that the protected person is always in danger and needs protection, does this prove that the old incident of 20 years ago has not actually been silenced?

Zhong Sanpu stayed in the Nameless Mountain, waiting for them to return, he insisted on participating in the search for the blood clan, as a human cultivator who was about to touch the threshold of the Flying Immortals, he took the initiative to give up participating in the study of penance, and gave up the preparations before the catastrophe that might come, it can be seen how resolute the intention of revenge is, the three young descendants are all buried in the Liuyun Temple, and the old man is really crazy.

The old case 20 years ago, codenamed 'Operation Wind and Thunder', has only a few thin pages, expounding the simple process of the operation that year, from the selection and finalization of the plan, to the selection and training of personnel, the formation of channels, and then to the implementation of the operation, and finally failed.

Xiao Yanda, the implementer of the plan, twelve members of the action team, and Zhou Tongwen, the leader of the group, had a one-line contact with Xiao Yanda, and the team members included Li Tianqi and Zhang Zhiqiang, of which Fang Jun was the only survivor after the operation, and Fang Jun also died a few years later, in fact, there was Zhang Zhiqiang who was exiled abroad, and later repeatedly entered the country, and finally became crazy, which is another case.

As for the reasons for the failure of the operation, only two sentences were lightly mentioned, because due to the exposure of the secret line of overseas communication, the passage was destroyed, and the action team lost the best opportunity to evacuate, which is a bit of an exaggeration.

As for Li Tianzhen at that time, he naturally died in that operation, and now Li Tianzhen is another person with the same name and surname, whether it is the archive or most people who know about this matter, they think so, and it has been determined.

But the instructor, Gu Changfeng, Old Man Dong and even Shen Wenyu and Xiao Yanda belong to the minority among the insiders, and they know that the current Li Tianzhen is the Li Tianzhen of the past, and this kind of grotesque thing is unexplainable by common sense, and it is also difficult to accept.

Earlier, the instructor wanted to re-investigate the old case, Xiao Yanda resolutely opposed, and the two of them fought and stopped, and tossed for a long time, until another Li Tianji appeared, although it sounded absurd, but it broke this situation of fighting but not breaking.

The contradiction is sharp, it can't be cleaned up, Zhang Zhiqiang failed miserably in the fierce conflict, the instructor and Li Tianchou never fell in the shaking, but the relationship between the Zhang family and the underground palace was completely revealed, judging the situation, Xiao Yanda immediately retreated in a low-key manner, and didn't even think about maintaining the previous stalemate situation, retreating thousands of miles, this is the weirdness of which no one knows, but unexpectedly, the discovery of the underground palace opened Pandora's box, and the alien invaders intensified.

With the awakening of Li Xiucheng's Yuan Shen, Li Tianzhen no longer cares about the events themselves, because the nightmare in the early years has given him too much torture, he actually doesn't need to read the file to roughly understand what happened, he only wants to know three points, who led the planning of the 'Wind and Thunder Operation'? Several participants at that time, retreated, died, and even Xiao Yanda died, is there anyone in the know?

Second, another explanation for the failure of the operation is the failure of the rescue, so how did the old man who was about to meet return smoothly? Why is there no news at any level mentioning this?

According to Li Tianzhen's understanding, at that time, the 'Wind and Thunder Operation' should be a bright and a dark, there were two groups of people and horses acting at the same time, and the people and horses in the bright place naturally had to cover the people and horses in the dark place, so there was a part of the dark Chen Cang, in fact, the operation was very successful that year, unfortunately, the people in the bright place failed to run back after all, Li Tianzhen and Zhang Zhiqiang and others were among them.

Old man Dong smiled awkwardly, and did not comment on Li Tianji's analysis, although he was an insider, he did not participate in the planning of the year, he couldn't say it, and he didn't know how to say it.

The third and most important point is, what is the background of the rescued old man? Why does Old Man Dong think that it is related to the pattern in Zhong Sanpu's hand? Is this also a reason why Old Man Dong finally gave in?

About to see each other, Li Tianzhen was a little cramped and uneasy, and suddenly there was a picture in his mind, it was still the familiar nightmare, in the wind-swept canyon, a group of young people sat around an old man to rest, they had been trekking for a long time, exhausted, almost everyone was injured in the fierce battle, the old man's appearance was very hazy, how to identify it could not be seen clearly.

I don't know when, Li Tianji was woken up by the old man Dong, and finally ended this bumpy journey, he was surprised that he could still fall asleep inexplicably in this upset state, and he couldn't help but feel a little confused, looking around, his eyes were full of lush greenery, and there were faint gray buildings with very low-key appearance and color, and after a little perception, he could find that there were secret sentinels and guards everywhere around the building, and he couldn't help but be surprised, which reminded him of the secluded life after returning from the mission to southern Yunnan.

After a short stay in front of a three-story building, the middle-aged man quickly completed various procedures, and Old Man Dong and Li Tianqi finally met one of the two old men of the year, Ouyang Tianpeng, in a bookish office.

The old man has white hair, a little fat, although he is over eighty years old, but he does not look old, his face is full of red light, he is in good spirits, he is concentrating on reading, and he doesn't care much about the staff's briefing, he waved his hand casually, and let Li Tianzhen and the two wait on the sofa outside.

Li Tianzhen was worried that Old Man Dong was irritable, and Old Man Dong was worried that Li Tianzhen was arrogant and disdainful, but he didn't expect that both of them were quiet and silent, waiting silently, without any impatience, at least showing that calm.

The old man finally released the scroll, took off his glasses and soothed his temples, Li Tianji carefully observed the old man's face, trying to find out the similarity of the old man shivering in the quilt from the nightmare picture, but unfortunately, no.

"I'm short on time, so let's get straight to the point. The old man was very cheerful and direct, he knew in advance that there was a visitor today, but he did not know what kind of person or thing it was, and he did not seem to bother to ask the identity of the visitor.

Li Tianqi and Old Man Dong glanced at each other, but Old Man Dong spoke first, "Excuse me, we belong to the security department, and we want to know about an old case twenty years ago, which is about your return from abroad." ”

The old man blinked, as if he didn't have much touch on the old past, and after pondering for a moment, he said, "It's too general, can you be specific?"

"Don't talk about the experience, I want to understand, why did you go abroad at that time?" This question is the key, what Li Tianzhen wants to know is also the background of the old man, but he doesn't know if the other party will answer directly, he and the old man Dong came to see Ouyang Tianpeng, except for a sentence of abiding by the discipline of confidentiality, they did not get any normative hints and references, what can be asked, what can not be asked, it is not too easy to grasp.

"In order to track a UFO. Unexpectedly, the old man had no taboos.

"UFOs?"

"That's right, it's what people often call UFOs. ”

"Where was the UFO observed?"

"In the area of Xiaoqinggou in Mobei, I can't say the specific location. ”

"Understood. Li Tianqi nodded, "So you are an astrophysicist?"

"It's pretty much the same, but I was the first to do nuclear physics. ”

No wonder it is so secretive, it turns out that this old man Ouyang is also a meritorious old-timer in the scientific world, it sounds like physics, a nucleus, a celestial body, and the difference between the two directions is 108,000 miles.

"At that time, I went to the site for an ideal impact point, but I didn't expect to pick up the grass and hit the rabbit, and found that strange flying machine, which was very dazzling, blood red, and Lao Zhao and I saw it, but unfortunately the camera at that time was not clear, and the effect of washing out was very poor, and it was blurry. ”

"Do you see the shape?"

"The long one, not the kind of flying saucer shape that is common in imagination, but the shuttle dart-shaped, such a strange flying machine, can actually stay in the air for a long time, the reason why I call it a flying machine, is because this thing has an obvious starting speed and acceleration process, Lao Zhao and I saw it for several days in a row, and at that time I made a report to the level, ready to stay and observe. ”

"Then why did you end up outside the country again?"

"Won the lottery. The old man's eyes flashed with inadvertent brilliance, sounding very humorous, but in fact he had an indescribable dangerous experience, "In other words, he was lost." The flying machine disappeared for two days and then reappeared, circled in the sky several times, and then landed in a col in front of us.

"The car was given to the comrades who went back to report the news, we were on foot, looking close, looking at the mountain and running a dead horse, we walked for a small half a day and finally arrived in front of the mountain, seeing that there were still a few miles of road, along the mountain with a big bend into the col, but Lao Zhao was sensitive, he found that there was something wrong in that area, they were all wastelands, but the color of the surface was obviously different, the closer to the mountain, the darker the color, and he was dizzy, he reminded me, I was also a little dizzy, and panicked, so I discussed it and stopped advancing.

"I have been running out all the year round, and I am engaged in this business, and my experience tells me that with Lao Zhao, the mountain not far away is likely to have a strong magnetic field, so let's observe it first. ”
