The mountains and fields in the early morning are refreshing, and the baptism of rain overnight makes the green mountains appear more towering, and the lake is rippling, and the waves of last night can not be seen at all.

Sha Dutian stood on the balcony, stretching his waist, the sun had not yet gotten up, the eastern sky was bright, and the clouds in the sky were very lovely in the gray air shrouded in the morning light.

Sha Dutian said: "Mentally handicapped, this sleep is really comfortable, the air is fresh, there is a different flavor, look at you, young, with a worried face, like a person who has not woken up, this is not good." Last night, this guy snored all night and slept until dawn. Zhao Ruozhi complained: "You sleep like a dead pig, can I sleep well."

"Get up." Summer said. Zhao Ruozhi turned his head and saw the smiling summer, and suddenly felt much better.

Before Zhao Ruozhi could be happy for long, Lu Shuiyi walked over, and Zhao Ruozhi remembered what happened last night, and felt guilty in his heart.

Sha Dutian ha: "Little girl, what delicious food did you cook today?"

Summer snorted, "I won't tell you." Sha Dutian's face was squinting, which made Summer look very disliked, so he didn't want to answer his question.

Sha Dutian laughed and walked into the living room.

After breakfast, it was six o'clock in the morning, the sky gradually brightened, the weather after the wind and rain, it was really good, blue sky and white clouds, just the sun climbed up the branches.

Ge Yiyan, Zhao Ruozhi, Sha Dutian and Lu Shui have already set off, and the place they are going to this time is not very far from the villa, about 200 kilometers.

Stretching mountains, the villa is 200 kilometers away from the destination is already very good, starting from the villa, Ge Diyan drove the car, all the way are green mountains and green waters, but Liao is uninhabited, many places even have no road, Ge Diyan drove an off-road vehicle to drive a road.

It is estimated that Ge Diyan has long been familiar with this place, and she is familiar with the road.

200 kilometers of mountain road, the car drove for 6 hours before stopping.

Ge Yiyan said: "The terrain ahead is steep, and there is no way for the car to drive in, so now we can only move forward on foot."

The place where the car was parked was very private, and no one would come here, so the four of them got out of the car and looked forward to the scenery here.

Along the way, Zhao Ruozhi was wondering why he didn't come with him in the summer. When he set off, he looked at Summer's outfit and seemed to be going far away, and he thought that Summer would come with him, but who knew that Summer left alone, he felt very strange, but he was embarrassed to ask.

If you want to say that the scenery is beautiful, it is the place where no one comes is the most beautiful, except for Ge Diyan, the other three people were immediately attracted by the scenery here.

It's April and many of the flowers have long since faded, but the hillsides here are full of colorful and beautiful flowers. The green hills are not very high, and the mountains are full of trees, and most of the young leaves of the trees have long been crushed with branches.

Ge Diyan said: "Okay, let's go, walk forward from here, about five kilometers away." She said lightly, and then stepped forward.

After walking forward for an hour, they heard the sound of rushing water, and along the way, they did not encounter any fierce animals and monsters, but more birds singing, accompanied by the fragrance of flowers in the mountains and forests, it was really a paradise.

The air suddenly became moist, and it was mixed with a hint of coolness, and when he turned the corner, Zhao Ruozhi saw a river.

The river is tens of meters wide, you can clearly see the direction of the river's flow, there are some leaves falling on the surface of the river, like a small boat floating on it, the river water is very clear, many places are crystal clear, it does not look very deep.

The river flows to the south, I don't know where it will go, and there are many rivers in the vast land, and a river like this is just one of the ordinary rivers.

After everyone approached the river, they obviously felt a cool air, the current weather is not particularly hot, plus a cool air, Zhao Ruozhi shivered directly.

Ge Diyan pointed to the direction of the river and said, "Follow here, you will be there soon."

Zhao Ruozhi guessed that this river must have come after the snow on the snow mountain melted, and even the cold of ice and snow was brought over.

Lu Shuiyi likes to pin the spare saber at the calf, and was walking, when suddenly a stone flew from her feet, hitting her calf directly, she looked at the small stone suspiciously, bent down the willow waist, and reached over in confusion, after touching the stone, she found that the stone was tightly sucked on her calf, she took off the small stone casually, and faintly felt that it and the saber on the calf had a suction.

Ge Diyan walked in the front, she noticed that there was movement behind, so she turned around, she saw the small stone and said, "This is magnetite ore, I saw it last time, don't worry."

Zhao Ruozhi looked at the magnetite ore in Lu Shui's hand unexpectedly, it was slightly red, he looked around again, there were not many stones, he wondered how could there be magnetite here, could it be that there was magnetite here?

Lu Shuiyi casually threw the magnet into the river, and with a plop, splashed drops of water, and the splash fell into the water again, causing ripples in circles, and the leaves on the river surface also fluctuated.

Lu Shui pulled out the saber on her calf and stuck it in her lower back, she didn't want any more stones to suddenly suck in.

After walking for a while, suddenly, there was a surge in the river, and I don't know what it was, I swam by quickly, and with a bang, it disappeared without a trace.

Although the four of them walked by the river, it was not a river in the real sense, after all, there were a lot of trees and weeds growing on the riverside, plus their attention was under their feet, the terrain here was complicated, and there would be danger if they were not careful, so no one cared about the situation of the river.

Sha Dutian asked, "What is it?" Could it be that the fish is turning over? This fish is really not small, if you can catch one, today's meal will be settled. ”

Ge Diyan frowned, judging from the speed at which the name cut through the water just now, it was not a good kind, she said quietly in front of her: "Everyone be careful."

Zhao Ruozhi was also a little worried, but since the thing was in the water, the place where he was standing was far from the water, even if it was a dangerous fish, it was estimated that it would not endanger his personal safety.

Lu Shui stared at the river and smiled slightly, and continued to walk forward.

The twists and turns of the river did not know where to go, and he seemed to be a little playful, flowing forward as he pleased. But the four people on the shore can't come and go as freely as it does. The environment on the shore was complicated, but fortunately there were no poisonous snakes and beasts, but even so, the difficult journey made the four of them waste a lot of energy.

The high and low terrain had already made Zhao Ruozhi tired and half dead, but fortunately there were many trees here, and he could still pull those trees to help him.

Finally, Ge Diyan, who was at the forefront, said, "It's coming." Zhao Ruozhi, who was at the back, gasped and said: "My mother, it can be regarded as coming, this deep mountain and old forest, in the wilderness, there is no road, and it is really difficult to walk." He thought of the Qinling Mountains he had been to, although it was also a mountain forest, it was not as difficult to walk here, the terrain here was steep, and the altitude was slightly higher, so it was no wonder that it was so difficult to walk.

Zhao Ruozhi finally followed, and then he heard a roar, which was the sound of the water rushing to the ground when the water formed a waterfall, and the sound was like the sound of waves and thunder.

However, Zhao Ruozhi looked at it for a long time, but he didn't see any open places, what was going on with this waterfall?

Walking to the source of the sound, Zhao Ruozhi looked amazed, no one would have thought that such a big river would flow into a big hollow.

The big hollow is 50 meters wide, and after the river flows here, all of it flows into the big hollow, and the bottom is not visible. There are many plants growing on the cliffs of the big hollow, and the river washes the rocks and the plants inside, who would have thought that such a large river would flow into the ground.

Zhao Ruozhi only remembered now, Ge Yiyan said that the place where the black box is located is an underground river, is it this river? He looked at the rushing river, the icy water, and couldn't help but feel a sense of fear in his heart.

At this time, it was already two or three o'clock in the afternoon, and after a difficult trek all the way, and finally reached the destination, everyone had no joy, but an irrepressible sense of solemnity.

Ge Yiyan took out the map, she pointed to the place not far from the connection between the river and the hollow, where there was a stone tablet, she said: "This is the Lengshui River, you see the direction of this river, it is exactly the same as the map drawn, although the map does not say the name of the river, but the stone tablet on the map is exactly the same as the stone tablet here, therefore, I guess this is the place recorded in the map."

Zhao Ruozhi remembered that the stone tablet on the map was only a little small, and he didn't care about it when he looked at the map at first, but he didn't expect it to become the key.

Since he came, Zhao Ruozhi didn't want to refute anything, he saw Ge Yanyan's serious face, and he probably cared about the black box thing. The summer who was with her didn't know where she went, and the man in black who broke into the house last night didn't know what to do at this time, and it was not something he could control when things got to this point.

Sha Dutian looked at the hollow below and said, "Good girl, such a deep hole, we won't want to go down, right?" The air was filled with the smell and coolness of the river, and he quickly stepped back.

Lu Shui smiled and said, "Yo, are you afraid?" She also looked down, the black hole below, she couldn't see anything at all, it seemed that this place was indeed not shallow, she thought to herself: "Who has such a big stroke, actually hiding the black box here, if you use a rope to go down, is there another cave down here?"

Ge Yiyan said: "You guessed it, we do need to go down, I don't think we need to rest here overnight, it's like night below, we are here to replenish our physical strength, and then we will prepare to go down."
