Since you don't know the details, you will always know something about the appearance.

Ye Zhenzhen asked: "When did those helicopters start to appear, and when do they usually pass over the leprosy village?"

"I know that. Li Dazhu recalled, "In the past, there were very few planes passing by in the leprosy village, until more than a year ago, there were more planes in the sky, at first there were five or six times a day, after more than a month, the number of planes passing by became less and less, and it became twice a day, and then once every two days, until more than a month ago, it became twice a day." ”

Both Vera and Alex felt that something was wrong, and Alex asked, "How many planes passed by the day you picked up the ring?"

Li Dazhu thought for a while and said: "It was raining that morning, I didn't go out, I listened to the radio in the house, because of the thunder, the signal was not very good, when I adjusted the channel, I clearly heard the sound of an airplane, the sound was close to the roof, it felt like a thunder could be chopped down, and there was an interval of more than an hour, and another plane flew by." Later, when the rain stopped, I went up the hill to look for mushrooms, and halfway there, I heard a plane flying in the sky, and I looked up, and oh my god, the plane flew past the treetops, and the wind almost blew me up. ”

"There were three planes passing by that day?!" Ye Zhenzhen pondered why there was one more plane flight here on the day of Senior Nan's disappearance.

Alex asked Li Dazhu, "Did you see the plane clearly?"

"It's like a helicopter on TV, with a red and white pattern. ”

"Are there any special markings on the helicopter?"

"Aren't all planes the same, what's so special?"

There are only a handful of types of planes that Li Dazhu has seen, and he can't tell the special features of the planes.

Ye Zhenzhen asked: "Is this the place where the plane passed at that time?"

"It's not far from here. ”

Zhen Zhen looked up at the sky, through the dense canopy of the banyan forest, the sun was slanting in, the sun had risen, "At this time, will there be a plane passing by?"

"No, it won't. Li Dazhu replied affirmatively, "There won't be one today, and it's strange to say that more than half a month ago, since I picked up that ring, no plane has passed through the leprosy village." ”

Vera and Alex looked at each other again, and a question appeared in their eyes at the same time, and sure enough, there was a problem!

Alex: "Did the ring really fall from a helicopter?"

Ye Zhenzhen: "It could also be that the people on the helicopter passed by here after getting off the plane nearby, fell down or deliberately stayed. ”

Li Dazhu also analyzed: "It may also be washed down from the upstream, there are cave dark rivers everywhere near here, and the water of the banyan forest flows out of the dark river in that mountain." ”

"The water here is very slow, and the diamond rings are dense, and it is very difficult to wash it away at this speed. ”

Li Dazhu: "As soon as it rains, there will be a flash flood here, and the stones can be washed away." ”

Li Dazhu's words also made sense, Ye Zhenzhen raised her head and looked around again, against the direction of the river, through the light beam of the canopy of the banyan forest shining on the surface of the river, dotted with stars.

On one of the surface of the river, the light was particularly dazzling, as if something was reflecting from beneath the river.

Zhen Zhen waded into the river, the shallow water surface was not up to her ankles, different from the wet mud on the shore, the bottom of the river was sand and gravel, stepping on the sand and gravel, going upstream.

Walking to the reflective surface of the river, I leaned over to see a silver-white chain lying quietly on the sand and gravel at the bottom of the river.

Zhen Zhen picked up the chain and looked at the shape and material of the chain, this is a platinum necklace, the chain buckle is a heart-shaped shape, the inside of the heart-shaped chain, "N, Y" two English letters, this is when the chain was repaired, Nan Zhiqiao specially asked people to engrave it, representing the initials of Nan Zhiqiao and Ye Zhenzhen's names.

This chain belongs to Nan Zhiqiao, and he usually wears this chain with a "life ring" ring around his neck.

Zhen Zhen was excited, and felt that she was one step closer to Nan Zhiqiao.

Seeing that Zhen Zhen fished out something from the river, Alex and Li Dazhu both came over, and seeing that it was a necklace, Li Dazhu was pleasantly surprised: "Not only a ring, but also a necklace, look for it, there may be other valuable things." ”

Li Dazhu immediately leaned over and found it in the water of the banyan forest.

Alex saw that Zhen Zhen's face was wrong, and hurriedly asked, "What's the matter?"

"This is Senior Nan's necklace, which I usually wear with the ring. ”

The ring and necklace appear here at the same time, and where is Nan Zhiqiao's person?

Ye Zhenzhen put away the necklace and pulled the young Alex to the shore, "Alex, in China, the take-off and landing of planes will be strictly controlled, and there will definitely be records of helicopters that have passed here, can you check these records?"

Alex gestured with an "OK" gesture, "I can enter the network of the General Administration of Aviation, and I will know when I check it." ”

Taking out the computer from his backpack, typing a few keys on the keyboard, sliding the mouse, Alex stared at the screen, and after a moment, smiled, "Found it!"

Ye Zhenzhen stepped forward, "Where are those helicopters, and what is the purpose of taking off?"

Alex pointed to a column on the screen, "Sister Zhenzhen, look here, this is the flight record of the plane that passed through Xishan in Baishan Town in the past year, this is the helicopter flight record, and the same time and sorties described by Li Dazhu are all here." ”

The computer screen displays a column of flight records, in which the aircraft belongs to the Nanmu Group, and the purpose of the flight is to take pictures.

"Nanmu Group?landscape shooting?" Ye Zhenzhen was full of questions.

In the past year, the planes that have often passed by here are actually Nanmu Group, and the official purpose of the flight is to shoot landscapes, what landscape shooting takes a year? And so many times a day?

Alex closed the computer, put it back in his backpack, and asked Zhen Zhen beside him, "Sister Zhen Zhen, what is the Nanmu Group doing?

Zhen Zhen shook her head, "I don't know, Zhi Qiao rarely tells me about the Nanmu Group, except for the Tinder No. 1 Base and the Guojing Medical Center, he rarely interferes in the affairs of the Nanmu Group." ”

Alex: "I don't think helicopters are so simple, what is the scenery in this primeval forest that is worth flying by helicopter so many times a day, and it has been flying for a year, it doesn't feel like taking pictures, it's more like transporting things." ”

Zhen Zhen suddenly remembered that the insect laboratory of the Fire Snake Organization in the valley in the western suburbs of Beijing, as well as the undersea laboratory in Y City, and the stem cell research center before the explosion, these laboratories were all built in secret, could it be that there is also a secret experimental base of the Nanmu Group in this deep mountain? Who is the manipulator behind the scenes?

Zhen Zhen called Li Dazhu, who was still looking for a treasure in the river, ashore and asked, "Is there a place around here where I can hide a large laboratory or factory?"

Li Dazhu was asked with a blank face, "It's all forests here, there are no roads, how can any factory be built here?"

"I mean, if somebody were going to build a factory in this forest and they didn't want to be discovered, where would they be built?"

Li Dazhu didn't think about it, and replied directly, "In the cave, the mountains here are full of caves, and some caves are super big, and it is possible to hide an army in them." ”
