Qian Yang has been drilling in the soil for eight days, in fact, walking through the soil is not a big deal except boring, but a cold bath every day really makes him palpitate.

Early this morning, Qian Yang, as usual, found the right place to enter the water, dropped a secret mark casually, gritted his teeth and grabbed it into the glacier, found the end point of the last exploration on the side wall of the riverbed, and he drilled into the soil again.

After a long day of walking, he found that the soil was noticeably softer and wetter than the previous days, and it seemed that cold river water had seeped in from the loose soil.

Change is a good thing! Qian Yang mustered up his spiritual power and accelerated his progress.

"Bang!" came a dull thud from under the dirt.

"Oops?" Qian Yang screamed, it was the bridge of his nose that hit a hard object. Qian Yang, who was caught off guard, trembled in pain, and the spiritual power all over his body stagnated, and the earth escape technique was almost forcibly interrupted.

"What is it?" Qian Yang quickly stabilized his spiritual power and stretched out his hand to find what he had collided with. There were no fingers in the soil, and he could only use his sense of touch to make vague judgments.

"Iron rod? shouldn't it?" It was a slender metal rod, it felt very long, Qian Yang didn't touch the end after groping for a long time, but the diameter was not large, probably only the thickness of a finger.

"Steel wire, iron bar, flagpole, or what magic weapon?" Qian Yang tried to find something similar in his memory.

Suddenly, his eyes lit up: "Isn't this a steel bar for construction?"

If it is a steel bar, then there will definitely not be only one, Qian Yang began to look around. In order to prevent the recurrence of the tragedy just now, this time Qian Yang was more careful, put his hands in front of him, and slowed down his speed.

Sure enough, not far away, he found a lot of metal rods that were twisted or even tangled. Moreover, there was a thick layer of hard earth and stones wrapped around these metal rods, and when his earth escape technique passed through them, he could clearly feel a resistance different from the surrounding soil.

"If the metal rods are steel bars, then these hard earth and stones should be concrete wrapped in steel bars, right?"

Reinforced concrete is definitely not a product of the present era, and if there are any prehistoric objects left in this area, then ......

Qian Yang's heartbeat began to accelerate. Around this location, he once again expanded his search. His location was only forty feet from the Broken Ice River, and as he searched around, he got closer and closer to the river. The moisture of the surrounding soil grew heavier and heavier, and when he felt that he was almost about to rush into the river of broken ice to take a cold bath, he suddenly emptied himself and fell into a hollow.

Qian Yang lay on the ground and didn't get up, he stayed in place for a moment, there was silence all around, except for the slightly rapid dripping sound, there was nothing abnormal around. He secretly touched the ground with his hand, and the familiar feeling instantly activated his memory.

That's it!

Hard, flat concrete floors.

Qian Yang got up slowly, and as soon as his mind moved, a misty cyan light was released from his hand. "The locust bricks are worthy of being born as a magic weapon, and they are so cool for lighting. Qian Yang was in a good mood, and even ridiculed the green locust bricks. The green locust brick was connected with his heart, and suddenly he was praised, and he trembled with joy, and the light shot out became brighter and brighter.

With the help of the blue light, Qian Yang began to look around.

The smooth concrete walls, the regular rectangular space, and the rectangular doorway on one side of the wall for entry and exit, and the wall opposite the doorway has a nearly complete window frame.

There is no doubt that this is a prehistoric room. There are no decorations or objects in the house, and the house is still relatively intact, but the traces of the disaster can still be easily seen.

The room was visibly tilted in the direction of the Broken Ice, and the corner above it had vanished. It was close to the riverbed, and the river slowly seeped in through the roofs and walls, and the lower half of the house was already knee-deep.

The room was empty, and Qian Yang walked out of the doorway, and what came into view was a spacious corridor, and on both sides of the corridor were rooms one after another.

This is a rather large building in prehistory, and Qian Yang looked at the rooms one by one along the waterlogged corridor. The rooms were large and small, some intact and some had long since collapsed. The same thing is that all the rooms have no items, no decoration, and no doors, and some are just door openings reserved for doors.

This is an unfinished building, only the building is intact, the interior has not yet begun to be renovated, and there is no trace of human activity. Qian Yang was quite familiar with the layout of this building, and there was no doubt that this building was the new building of the Dongliao City Library, which had not yet been completed.

Qian Yang is here to look for relics, or to find treasures. Such an empty building really didn't have any value to him.

He was looking for the legendary ancient civilian cemetery, but his clue was the metal "picture" he had seen at auction. According to the "map", he really found the ruins of the library, but where is the expected cemetery? Is it nearby?

Qian Yang looked around, but found no traces of exploration in the building, and it seemed that the monks of the Infinite Valley had not entered here.

"Let's look around!" Qian Yang was about to leave here, the empty building was really not worth exploring.

"Huh?" Qian Yang was just about to turn around, when his eyes suddenly lit up: "Who said that there was nothing in this building? If there was nothing in this building, how could he stay here at that time! And if those things are still there, it is definitely a priceless treasure!"

Qian Yang flipped through his memories and compared the current layout of the building, he should now be on the fourth and top floors of the building, and what he was looking for was on the basement floor of the building.

Unable to suppress the anticipation in his heart, Qian Yang found the stairs three times and two times, stepped up his pace, and walked downstairs. On the third floor, the second floor, and the first floor, Qian Yang's brows slowly wrinkled. The entire building is still intact, but the water is deeper than the first.

Qian Yang hesitated to wade into the water and entered the first floor, the current horizontal position should be lower than the bottom of the Broken Glacier, and because the building itself is seriously tilted, it may have even been inserted diagonally directly below the Broken Glacier.

The faint sound of running water came into Qian Yang's ears, and the cold river water slowly seeped into the building through the soft soil, and Qian Yang couldn't help but start worrying that the rushing river above his head would crush the dilapidated building at some point. Even if the riverbed will not collapse in a short time, the water on the ground on the first floor is already knee-high, and the situation on the basement floor is really not optimistic.

It was useless to think about it, Qian Yang held his right hand holding the brick, endured the biting cold, and slowly entered the basement floor.
