In fact, the first underground hydropower station was built in Germany as early as 1904, and there were more than 350 in the world in 1977. Although it sounds a bit incredible to hollow out the mountains to build a hydropower station, in fact, the project of the underground hydropower station is easier than that on the ground, because there are a large number of criss-crossing three-dimensional caverns that can be used underground, and they can be connected and widened with tunnels, and the water flow of the tributaries can be diverted to the main diversion canal, and the principle of power generation is also to use the drop.

The place where the group jumped down was right in the main water diversion canal, and on one side of the hollowed-out iron plate bridge was a huge generator set, and the flowing water slapped against the waterwheel-shaped generator set below, making a deafening rumbling sound, so loud that they had to shout when they even spoke to each other.

Dai Xue took out a flare gun from her backpack and fired a flare in each direction, under the strong light, she saw that the roof of the cave was densely covered with upside-down stalactites, reinforced with concrete in some places, and the anchors were densely placed on it, arranged in a matrix style to prevent the concrete shell from falling down.

There are many inlet canals around it, from which the raging underground river flows into the main channel, and the entrance is turbulent and stirring up a whirlpool.

"Look over there." Dai Xue pointed in one direction, and the group looked there, and there was a long fire ladder on the side wall of the huge cavern, and a row of cave-like houses, most of which were where the workers lived.

"Let's go!" Yan Chop Butterfly said.

A few people walked down the iron bridge, walked along the river bank for a while, and went up to the fire escape. The fire escape was so long that people walked on it and staggered as if it might fall down at any moment, but in the end everyone entered the "cave" safe and sound.

The room was very dark, and Dai Xue casually touched the pull cord of an electric light, dragged it down, and the electric light turned on. The layout here is simple, with a large control panel facing the windows. There were tables and chairs, on which were placed enamel jars, bowls, a crumpled and yellowed magazine, a deck of playing cards; There was a bed, but it looked like the quilt hadn't been dried for a long time, and Jin Duan touched it with his hand, and it was so wet that he could almost squeeze out the water; There is also a cabinet with glass with commemorative medals, photo racks, and some instant noodles.

The hungry team immediately pounced on the instant noodles, there were only five packets in total, there were more monks and less porridge, and there were no guys who cooked noodles here.

Zhang Yi borrowed a knife from Forging Armor, opened the wet quilt, and said to Yan Butterfly with a smile: "Old Yan, come and eat cotton, you can swallow it directly if it is so wet." ”

", I don't eat such dirty things."

Jin Duan pointed to the groundwater rushing outside and asked, "Is the water clean?" ”

"As clean as my heart!" Zhang Yi said.

Jin Duan frowned, knowing that he was joking, so he took the bucket and rushed down to fetch water, Zhang Yi shouted in the back: "The bucket is very dirty, you have to wash it first." ”

"Got it!" Jin Xuan, who ran away, responded.

The group rummaged through the rows of rooms, much like they were playing an RPG game, but instead of treasure, they were looking for food. After a few moments, everyone met in the lighted control room, and the looted food included a packet of dried sweet potatoes, a hanging bacon, two packets of dried noodles, and a few bits and pieces.

Several people got together to discuss how to eat, and someone suggested that a pot was boiled, Zhang Yi said: "Don't put the sweet ones in the pot, otherwise it will be very disgusting." Forget it, I'll do it, you guys go around. ”

"I'll help." Insect Ting said.

"How can you help with cooking noodles, let's play while you go."

In fact, there is no pot here, so you can only use that bucket to cook things, and the fire is naturally from the worms. Zhang Yi washed the bacon and cut it into thin slices, threw it into cold water and boiled it, boiled it for a few minutes, threw noodles into it, and beat eggs. The others were already so hungry that their stomachs were about to turn over, and they were all watching with their eyes on the side, and their saliva was almost hanging on their chests. …,

"That's it!" Zhang Yi smiled and lifted the lid of the pot, and the fragrant heat made them almost cry, of course, they were moved to tears.

"Fourteen people, how do you divide them?" Forging asked.

"Guess the box."

"PK, whoever wins wins wins and eats more."

"You came up with this bad idea?"

"It's a bit underwhelming." Zhang Yi handed over the bag of dried sweet potatoes, "Come, each person uses this pad a little, and then drink more soup, this game will swell when you see the water, and ensure that your stomach will not be hungry." ”

"Trick yourself into your belly?" Yan Chop Butterfly said.

"If you don't like it, eat cotton, cotton is there."

Everyone grabbed a little dried sweet potato and stuffed it into their mouths, all of them frowned, and the people present usually don't have to think about eating, but now they have fallen into such a field.

A circle of people patiently chewed the unchewable dried sweet potatoes around the fragrant "cauldron", their chins moved in a circle, and Jin Duan complained again: "It's good that Lu Su is here, you don't have to suffer this crime at all." ”

"Girl, shut up, you've been complaining all night."

"It's sweet to chew on this hard-tied thing." Insect Ting said.

After this ritual-like pre-dinner play, Zhang Yi served noodles in three square lunch boxes, one shared by several women, and the other two by the men in turn.

Hungry and Zhang Yi's craftsmanship is really good, the bacon is naturally cooked with oil and saltiness, no seasoning is needed at all, the noodle soup is tempting white, and the noodles are also cooked very strongly, and the roots are not sticky together. When the noodle soup was drunk, everyone praised it, and Zhang Yi boasted proudly: "Don't look at it as instant noodles, it's also very skillful to do well." ”

"It was the most memorable meal of my life." Someone sighed.

Zhang Yi said: "What is this, when we go to school, we can't eat enough at night, so we pour raw rice into a hot water bottle, and it becomes porridge overnight." But there are no pickles when I drink porridge, I can only take a piece of coarse salt, lick and drink a sip, and now I have noodles to eat and meat to eat, and the conditions are not known how many times better...... Another time I ate instant noodles at night, and after eating, I was smoking and reading a book, and I threw the cigarette butts into the noodle soup, and one of the unlucky people in our dormitory came back, and he was hungry from playing ball, and he took the bowl of noodle soup and drank it, chewing it as he went, and said, 'This beef is really chewy!' ’”

Several people burst into laughter, and the most exaggerated noodle squirted out of his nose, Yan Chudie frowned, and subconsciously shook the handle of the knife.

In fact, there was not much content in a bowl of noodles, so I could only drink more soup to deceive my stomach, and soon a large bucket of noodle soup bottomed out, and several people's stomachs were swollen, and the hunger was finally quelled.

"What time is it?" Yan Qidie asked.

"It's about ten o'clock." Kinoshita replied.

"Guys, there's not much time to rest, let's get ready to go."

"Oh!" Several demon slayer replied in unison.

Kinoshita said, "I just looked at the map on the wall, and if you pass through the iron bridge below, you can probably pass through the shrunken area. We walked to the ground where there was no way in front of us, and then drilled holes and drilled up. ”

"Let's go."

……

When a few people were there trying to fill their stomachs, the screen in front of Lu Su's eyes only showed a small piece of the iron plate bridge, and there were not many monitors in the underground power station, so he didn't know where they were.

The picture was taken with night vision surveillance, the long iron plate bridge and the flowing water below emitted a layer of faint white light, and the picture was too rough with many particles beating, much like the image of a horror movie.

Lu Su pretended to be looking at this boring picture carefully, but in fact, he had been observing the change in the expression of the heavenly injury on the other side, the narrowly arranged reduced area only killed one person, and the group of people drilled through the bottom with a hole, why did the heavenly injury not show a disappointed and angry expression, and there was still a faint disdainful smile on the corner of his mouth. …,

Could it be that they have prepared a trap for this seemingly safe underground power station!? The light here is very poor, the surrounding large and small caves are criss-crossed, and there is a rushing water below, if you fight here, I am afraid that the situation will be even worse.

Also, with the camera pointed at the iron bridge beforehand, it was clear what was going to happen here.

He asked tentatively, "You seem to be sure." ”

"Human beings are so stupid that they think they have found a shortcut, but they are actually sending themselves into the mouth of death." He raised his eyes to look at Lu Su, "It's almost the end of this feast, I want you to see your companion and lover die there." ”

"You've ambushed a lot of people here?" Lu Su glanced at the screen, where there was a large dark area.

"No, I don't need a lot of people." Tiansheng smiled coldly, "One person can wipe out all of them, so you can obediently wait here for the show to play out." ”

"That Ty? Or is it Wan Rong Bing? ”

"Neither, I don't want spoilers."

In the picture, the group of people had already walked to the iron plate, completely unaware that the people who had walked into the ambush looked around, and the corners of the mouth of the heavenly wound who were obliquely propped up showed a sneer of conspiracy.

If the natural injury didn't lie, and the environment surrounded by water, it stands to reason that it is the most convenient for Tai to kill people...... But even if he wanted to kill them all, it was unlikely.

Wait, this place is a long cave, and if there is a person who is ambushed here, they have no hope of survival......

Thinking of that person's name, Lu Su suddenly broke out in a cold sweat...... "Collapse Mountain Angry Cannon" Wu Nianqiu!
