Yu Yao nodded solemnly when he heard this, and the two of them came to the east side of Xianding Mountain along the surrounding mountain road.

However, the eastern slope is different from the other three sides, relatively steep, and the vegetation is particularly dense, perhaps because it is bordered by the river in the east.

The cliff at the top of the mountain is not slippery and hands-free, but a typical red rock formation of Danxia landform, with many uneven gaps, and it is not difficult to climb it with Xiao Ying's skill. However, now you can't rush up, everything is foreseen, and more importantly, there are tourists coming and going from time to time on the mountain road.

The two of them went down the mountain first, ready to see if there was any other way to go around to the riverbank on the east side of Xianding Mountain.

The east side of Xianding Mountain is the west bank of the Jinsha River, and near the west bank, there are almost all mountain walls, and there is only one low area that is not spacious, which is the end of the county road on the south side of Xianding Mountain.

And at the end of the county road, there was a big black iron gate, and the high walls on both sides also connected the mountains on both sides.

On both sides of the iron gate, there is a sign painted with white paint, which is also painted with imitation Song Heiti characters, one is: Tajiang Hydrological Monitoring Station, and the other is: 8665 Research Institute.

This 8665 Research Institute, Yu Yao and Xiao Ying have never heard of, but it is estimated that it is also related to hydrology. At the same time, Yu Yao vaguely felt that the reason why Xianding Mountain was not included in the Jinshajiang National Geopark may be related to this unit.

But if this is the case, it is said that the old gentleman who retired from the garden department should know, so Yu Yao thinks that his feelings may not be right.

On one side of the iron door, half of the communication room is revealed, a wall with a two-foot square sliding window, to be exact.

Yu Yao stepped forward and knocked on the window, and the window was opened, revealing a swarthy face, a man who looked to be about fifty years old, his eyes squinted at Yu Yao from above his black-rimmed glasses, "What are you doing?"

"I'm sorry uncle, we're here for a tour, passing by here, I want to ask, where can we walk to the river?"

"Isn't there a riverside tour in Jinjiang National Geopark?" replied impatiently.

Yu Yao was about to ask again, but he waved his hand, "This is a closed unit, let's go quickly!"

Without waiting for Yu Yao to answer, with a bang, the glass window was closed again.

Yu Yao smiled indifferently, this road seemed to be impassable. Xiao Ying looked at the high walls stretching on both sides, thoughtful.

"You might as well go to Jinjiang National Geopark tomorrow to have a look. Yu Yao spoke.

"It's fine. Xiao Ying nodded, and the two turned back the same way.

At this time, it was already evening, and after the two returned to the B&B, they had dinner on the rooftop of the second floor. The owner of the B&B sat at the table on the side while they were eating, tapping on his notebook, and suddenly raised his head in the interval and told Yu Yao and Xiao Ying that there was a bonfire party in the town at night, and if you were interested, you could go and see it.

The owner of the B&B is in his thirties and wears a pair of gold-rimmed glasses. This is a mom-and-pop shop, and the proprietress is a very refreshing young woman. The couple are not locals, they were both former financial executives in Shanghai, tired of city life, selling houses and cars, came here with all their savings, bought a yard to renovate, run a homestay, and support their family.

It takes a lot of courage to change their lifestyles, and their faces are punctuated by a heartfelt smile that makes travelers feel warm.

However, Yu Yao and Xiao Ying have little interest in the bonfire party, which is mostly a tourist project.

After dinner, the two didn't talk much and went back to their rooms to rest. At this time, he couldn't sleep too early, Yu Yao half-lay on the bed, chatted with Shen Ge on WeChat for a while, and suddenly remembered the 8665 Research Institute, but after checking for a long time, he didn't find anything.

At nine o'clock in the evening, Yu Yao and Xiao Ying hadn't fallen asleep, but Lin Fengcao arrived in a hurry, and said that he hadn't eaten dinner, and proposed to go to the bonfire party to eat together.

"How do you know about bonfires?" asked Yu Yao.

"When I came, I took a taxi and passed by, and in the folk village at the west end of the town, I saw a roasted whole sheep, and it was bubbling with oil. ”

Yu Yao and Xiao Ying ate very casually for dinner, and when they heard Lin Fengcao describe roasting whole sheep, they felt a little hungry again. Besides, Lin Fengcao has come all the way and hasn't eaten yet, how can they not accompany him?

The so-called bonfire party is essentially a "buffet", which temporarily pulls up an open-air area, buys a ticket to go in and eat as much as you want; in fact, there is nothing to play, it is a group of people dancing in circles around a bonfire, among which there is a leading dancer wearing a national costume singing.

But the food is really good, in addition to the roast whole lamb on the shelf, there are many special snacks. The environment here is very noisy, not suitable for communication, and the three of them are mainly eating and drinking.

Yu Yao watched casually while eating, and suddenly found a familiar face.

The swarthy man in the communication room of the 8665 Research Institute.

He was also eating, and there were two tables diagonally opposite Yu Yao, but he didn't seem to notice Yu Yao and Xiao Ying, his eyes were fixed on a woman who was eating with him. The woman looked to be in her thirties and forties, but she was in good shape. The two of them got tired while eating.

Yu Yao looked at Xiao Ying, and Xiao Ying nodded.

Lin Fengcao didn't know what was going on, and Yu Yao and Xiao Ying's complicated experiences in this area hadn't had time to be elaborated on, but Lin Fengcao was a smart person, and it seemed that this person should pay attention to it.

The men and women left together, the three of them followed secretly, Xiao Ying followed closely, and Yu Yao and Lin Fengcao were walking at a certain distance behind. Taking advantage of this opportunity, Yu Yao told Lin Fengcao about the discoveries and clues during this period of time.

As they spoke, the two simply stopped following Xiao Ying.

When he was about to finish speaking, Xiao Ying also came back, and his face was not very good. As soon as I asked, it turned out that the man and woman actually went to a small forest and had a fierce battle in the field.

When Yu Yao heard this, he raised his eyebrows, "Finding such a person to come to see the door shows that this 8665 Research Institute is not an important unit······

"What are you talking about?8665 Research Institute??," Lin Fengcao suddenly interrupted Yu Yao's words. When Yu Yao introduced him just now, he was about to talk about this research institute, but he paused because Xiao Ying came back.

"Yes, one gate, two signs, and one sign for the hydrological monitoring station. Why, do you know this 8665 Research Institute?" Yu Yao couldn't help but wonder, "I haven't found it for a long time. ”

"I know yes, but it's so strange! This should be a high-level classified unit, it shouldn't be in such a small place, and it should be mixed with a hydrological monitoring station!"
