Jinan has a long history, it inherits the remnants of Mount Tai, the terrain is high in the south and low in the north, and it is the birthplace of the prehistoric culture "Longshan Culture".

There is the Great Wall of Qi that preceded the Great Wall of Qin, and there is the Lingyan Temple, which is known as "the first famous sculpture in the sea".

And the Arhat of the Song Dynasty and the Great Buddha of the Sui Dynasty shocked the world.

The most representative, especially the seventy-two famous springs headed by Baotu Spring, crown the world, so it is also called Spring City.

This inkstone pond is one of the seventy-two springs, which resembles an inkstone, hence the name inkstone.

In the autumn of 1958, the people of the whole country made iron and steel, seized the mines, and left a huge pit here, which unintentionally touched the spring veins of Jinan, and led the spring water to trickle down and merge into a clear pond, with a pool surface of more than 6,000 square meters and a depth of 20 meters.

Ma Yu and Qiao Yufan stood by the pool, looking at the water quality of the inkstone pond, the spring breeze blowing wrinkled, the blue waves were not prosperous, the surrounding boulders were dangerous, the pool wall was steep, the green mountains and green water were close to each other, and the mountain shadow and red pavilion were reflected in the water.

Qiao Yufan tied a rope to Ma Yu's waist and carefully checked it left and right.

Ma Yu checked the camera on his head again, and then adjusted the picture on the monitoring screen.

"After I get in the water, you can see what I'm doing underwater through the camera screen here," he said. ”

Then he took out a small boxy box from behind him and handed it to Qiao Yufan: "There is a row of small lights on it, if the red light is on, it is a danger signal from me, you can quickly pull the rope and rescue me." ”

Qiao Yufan nodded and said, "Professor Ma, there is a mine pit down here, and the water situation is very complicated, isn't it too risky for us to do this?"

Ma Yu smiled: "It's okay, I'm very good at water, even if I don't have this water-avoiding golden crystal beast, this pool can't trap me, and I just do these measures just in case." ”

As he spoke, he patted Qiao Yufan on the shoulder, then walked to the edge of the pool and took out the water-sheltering golden crystal beast.

At this time, the blue water golden-eyed beast faintly shone with a layer of dark green light.

Ma Yu took a deep breath, grabbed the water-avoiding golden crystal beast in his right hand, and jumped towards the pool.

Only a "plop" was heard, and Ma Yu had already jumped into the pool.

After the water-avoiding golden crystal beast encountered the pool water, it shone brightly, stirring the surrounding pool water as if it were boiling, and separated a vortex left and right at the place where Ma Yu entered the water, surrounding Ma Yu.

Qiao Yufan stared at the surveillance screen tightly, and saw that the pool of water was less than five centimeters around Ma Yu's body, but it no longer poured in, but just wrapped him tightly.

With the help of his own gravity, Ma Yu slowly sank.

It works! Qiao Yufan was relieved.

Ma Yu is in the water, as if he is in a characteristic transparent bubble, but this bubble is not round, but the curve of his body forms the shape of a person at a distance of five centimeters.

The pool of water was isolated from the bubbles, and it was turbulent and tumbling but could not be poured into.

There are very small bubbles in my mouth that are constantly spewing out, and there are also small bubbles constantly entering, as if exchanging oxygen in the water, just like the fish.

Ma Yu couldn't help but be overjoyed when he saw that this water-repellent golden crystal beast had such an effect, which greatly exceeded his expectations.

When you first enter the water, the scene is clear, and the further you sink, the darker the light becomes, and you can't reach far.

Ma Yu leaned back, and as soon as his waist was forced, he swam to the depths of the inkstone pond with his head and feet.

After a short swim, the bottom of the pool gradually appeared, and some low woody plants grew at the bottom of the pool, with no skills or veins, and large and small rocks were scattered all over the place.

There is still a section of track between the rocks, and four or five meters away lie several minecarts, rusty, covered with moss, and nameless small fish, shuttling among them.

One end of the track was obscured by rocks, and the other end was stretched straight into a black hole more than ten meters away.

Ma Yu swam hard for more than ten minutes before he touched the bottom of the pool, he straightened his waist, straightened his body, and stood on a rock to look out.

I saw that the water at the bottom of the pool was steaming, the dark fog was boundless, and it was extremely dim as far as the eye could see.

Ma Yu stabilized his mind and squirted out the stagnant air in his chest, and then gradually adapted.

I saw that in addition to the tiles, bricks, benches, leather shoes and other discarded sundries under the pool, there were actually more than a dozen shared bicycles, which fell there horizontally and vertically, thinking that they were thrown down from above.

All kinds of utensils at the bottom of the pond are covered with moss, and fish and shrimp are playing on it.

Ma Yu stayed on the rock for a long time, breathing smoothly, as if on land, and wanted to continue to try the ability of the water-avoiding golden crystal beast.

He picked up a shared bicycle, kicked the rock hard, and rode the shared bicycle to the black hole at the bottom of the pool.

The black hole is an artificially dug mine hole, dark and gloomy at a glance, Ma Yu has not yet leaned in, he feels that there is a suction force in the black hole, and he is involuntarily sucked over.

Since Ma Yu entered the bottom of the pool, Qiao Yufan has been nervously staring at the monitor in front of him, the light at the bottom of the pool is dark, and the scenery is almost indistinguishable.

Qiao Yufan wanted to immediately pull Ma Yu out with a rope, but suddenly remembered Ma Yu's instructions before entering the water, and glanced at the row of small lights that were not on.

After thinking about it for a while, he finally lowered his hand again and stood on the shore anxiously waiting.

Ma Yu rode all the way down along the black hole, about a hundred meters, the terrain was slightly gentle, divided into two forks on the left and right, the left side had collapsed, and only a narrow road on the right was barely feasible.

The road became narrower and narrower, and it was impossible to enter the straight body, so I had to abandon the bicycle, bend over and slump back, and staggered along the waist.

After walking for a short time, I turned left again, and after four or five sharp turns in a row, a huge hall suddenly appeared in front of me.

The interior of this hall is stacked with various abandoned machinery and equipment such as road starters, extruders, and rail clamps.

Hard hats, shovel handles and other objects were scattered all over the place.

The rows of large characters written on the mottled wall of the hall are still clearly legible, and the left side reads: "There is no Jade Emperor in the sky, there is no Dragon King on the earth, I am the Jade Emperor! I am the Dragon King! I have the final say!"

On the right wall is written: "The river is urgent, the river is slow, we have to have the final say, call the water to go, the water will go, call the water station, the water will stand, call it high and dare not low, and let it generate electricity." ”

There are also a few big words written on the wall in the middle, "Bibi look, you are a hero, we are a hero, next to the blast furnace, you can refine a ton, let's refine a ton and a half; you sit on a jet, we can take a rocket; your arrow pierces the sky, we can circle the earth!"

Ma Yu approached and looked at them one by one, feeling full of pride in his heart.

Everything is covered with the dust of history, Ma Yu picked up a kerosene lamp that fell on the ground, stroked the moss on it, looked at the hall, and thought of the scene when the steel was in full swing.

Suddenly, the water trembled violently, and a cloud of white mist poured in from outside the hall, and for a time the hall was dark and foggy, and the waves were turbulent.

At this time, an object suddenly broke in from outside the hall, and there seemed to be a black gas around the object, wrapped in a mass of flesh whirring, and it rose slightly upward, and it was not very high. The water in the hall was steaming, and Ma Yu couldn't see it really.

The thing caught a glimpse of Ma Yu's sudden rage, two cold lights shot out of his eyes, and he rushed towards Ma Yu.

Seeing that the situation was not good, Ma Yu blocked the way from the monster, so he had to run inside.

Fortunately, although the monster was fierce, it was too fat, and its speed was reduced.

Ma Yu ran all the way, gradually distancing himself from the monster.

Ma Yu was secretly glad that he suddenly ran to the end of the hall, and there was no way on either side, only one big rock after another piled up in front of him.

The monster ran closer and closer, Ma Yu had nothing to hide, there were gaps between the stones, and Ma Yu had to take a risk.

So he slipped through the gap with his hands and feet, and the monster was fat but could not climb, and stood outside the hole and roared.

Ma Yu perforated through, there were stone walls in front of him, and there was only a dozen centimeters of space left in his side, and there was no way around.

Ma Yu took out a small box, opened the lid, put his finger on a button, and was about to press it when he suddenly hesitated.

I thought that if I sent a signal to Qiao Yufan at this time, Qiao Yufan would definitely pull the rope to pull him back, and he would have to drill out of the crack in the stone to return, wouldn't he be sending himself to the mouth of this monster?

Ma Yu hesitated, closed the small box again, and put it in his arms.

He prayed to the monster before it left on its own.

Unexpectedly, although the monster could not enter the crack in the stone, it was extremely obedient, and found that there was a long rope under his feet through the gap in the stone hole and tied directly to Ma Yu's body.

Ma Yu was shocked, and hurriedly untied the rope on his body, and the rope slipped through the hole and was pulled out by the monster.

The monster pulled into the air and fell solidly on all fours.

The monster jumped up and down as if it had been blown up. Suddenly, he aimed at the gap in the stone hole, opened his mouth, and a thunderbolt of lightning and flint erupted from the monster's air, shooting straight towards the horse.

Ma Yu hurriedly lowered his body, only to hear a series of loud noises of "click, boom", and the thunderbolt struck the stone wall in front of him, and the stone wall was shattered and knocked out of a round hole of more than ten centimeters.

Ma Yu saw that there was something else in the stone wall, so he didn't think much about it, so he leaned in and got in.

Inside the stone wall was a winding and rugged passageway, extremely narrow, and paved with red pebbles on both sides, which did not look natural.

Ma Yu walked a short distance along the passage, and suddenly his eyes lit up, and a white stone chamber appeared in front of him.

Although this stone room is small, it has a stone table, a stone bench, and a stone bed inside, as if it was inhabited.

Ma Yu walked to the stone chair and sat down, his heart settled down slightly.

Today's trip to the pool, I don't want to be so dangerous.

The rope has been lost, and the monster is holding the way back, how can he go back?

While hesitating, Ma Yu inadvertently looked up and couldn't help but change his complexion.

It turned out that he looked at the roof of the room, but saw that the roof of the room was engraved with patterns horizontally and vertically.

Ma Yu hurriedly got up and took a stone bench, and stood on it with his face up to take a closer look.

I saw that the roof was engraved with a map, and a few small characters on the left side read "The Road to the Xuan of the Pichu Realm", and the word Zhou Xuan was written, and Ma Yu was shocked.
