However, on the way, as long as it is some reasonable advice, Lin Meng will almost never refuse or oppose it domineeringly, which makes Retia, who once regarded Lin Meng as a great enemy, change his senses a lot, Lin Meng is now a second-level wizard, she does not dare to go beyond it, and she remains respectful enough along the way, otherwise Lin Meng will not mind a small punishment, even if the two sides have signed a contract.

"Let's go—" Lin Meng nodded, and the two of them flew towards the valley below.

"Now that you're in the place, how can you find out this ancient laboratory?" Lin Meng asked, he looked around, it was full of tall trees, knotted old vines, and the ground had already been occupied by various vegetation, and there was no trace of man-made at all.

"Lord Link, please take a moment. Rhaedia glanced at the terrain around her, and suddenly looked at a col not far from the two of them, where there was a protruding boulder, very large, almost the size of a room, which had long been covered with some green moss, and there were vines the thickness of an adult's arm, tightly wrapped around it, no different from the other boulders in the mountains, and there was nothing unusual to see.

Retcia stared at the boulder, her body moving, and slowly flew towards the col. In a moment, she flew in front of the boulder, reached into her arms, pulled out a fist-sized crystal, closed her eyes and groaned.

Staring at the crystal ball in the other party's hand, Lin Meng's eyes moved, during the two months of travel, whenever they lost their direction and couldn't determine where to go, Rhodia would take out the crystal ball to inquire, and then determine the direction of travel. At this time, her eyes were slightly closed, and she was completely immersed in the crystal ball.

Soon, Rhaedia's eyes opened, looked at the sun above, and then the mana in her hand fluctuated, and the crystal ball in her hand, exuding a strange light, slowly floated up, at this moment, a ray of sunlight in the sky, shot into the crystal ball, and suddenly the crystal ball burst out with brilliant light, reflected on the boulder, under the light of the crystal ball, the boulder revealed a stone door pattern.

Seeing the pattern on the boulder appear, Rhodia's eyes flashed with joy, and the mana in her hand continued to surge towards the crystal ball above, and suddenly the crystal ball shone brightly, all shooting towards the boulder.

"Boom—"

The boulder shuddered violently, and there was a rumbling sound inside, and then it slowly moved where the stone door appeared, revealing a large black hole, revealing a passable corridor.

The two of them flashed and appeared next to the boulder at the same time, Lin Meng glanced at Rhetia and saw that the other party was putting away the crystal ball.

"Lord Link, you can go in, if there's anything inside, I can't handle the danger, and I hope your lord will not hesitate to make a move-" Rhedia whispered to Lin Meng, and after speaking, her body moved, and she walked in first.

Hearing this, Lin Meng's face remained unchanged, nodded, and followed behind the other party, not long after the two entered the stone path, the stone door on the boulder slowly closed again, and then the light flashed, and the whole boulder merged into one, which looked no different from other stones.

Inside the Stone Mountain.

"Tap, tap, tap—" Footsteps sounded, one soft and sensitive, the other low and powerful.

Lin Meng and Rhedia walked unhurriedly in a dark and damp passage, there were obvious traces of artificial excavation on the stone wall, and every short distance above the stone path, inlaid with a glowing glittering stone, illuminating the passage as if it were day.

The passage is not straight, it is a little curved, Lin Meng can clearly feel that the two of them have been walking downward, and it didn't take long to walk out of the stone road, but there was a cliff in front of them, the two stood at the mouth of the passage, looking towards the bottom of the cliff, dark and heavy couldn't see the bottom at a glance, looking up at the top, Lin Meng saw that it was not very high, and it had reached the top.

The two of them had to walk along the stone steps that protruded from the cliff, one by one in a spiral staircase, towards the depths of the ground below, although both were wizards, and flying was easy for them, but in this mysterious mountain, both of them were extremely cautious, and would rather take a little more time to walk down step by step than fly directly below.

This time, Lin Meng was in front and Rhetia was behind, and the two were separated by three stone steps.

Half a day later, the two of them were still walking on the cliff, without the slightest impatience, and now they could not see the entrance where they came in, and when they looked down, it was still dark and gloomy, and they couldn't see anything.

Suddenly, Lin Meng paused and stared not far in front of him. "There's an entrance ahead—" he said.

"My lord, go in and have a look-" Rhedia was overjoyed when she heard this, and finally saw the other passages, and then she followed behind Lin Meng, carefully following into the hole.

"This is—" In the cave, Rhaedia, who had just flown in, looked at the scene in front of her, and couldn't help but change her complexion, and saw Lin Meng with a gloomy face, looking at the pile of dry bones in front of her, and in addition to this pile of dry bones, this cave was also forged with metal bars, divided into cages one by one, and covered with a thick layer of gray bones.

It was clearly a cell where the annoying people were kept, and they didn't know if it was a prisoner or anyone else. Lin Meng swept his eyes at the thickness of the bones on the ground with a calm face, and silently estimated in his heart how many people were here.

"Well, there are runes on it, and it seems that the people in this cell are not ordinary people. Suddenly, Lin Meng's complexion changed slightly, he stepped forward, stared at the cage made of stainless steel, and looked at it, on which he could clearly see runes the size of a fly's head, and the lines composed of them were extremely mysterious.

"Let's go, the smell here makes me a little uncomfortable. Suddenly, Lydia whispered, the breath in the cave was a little oppressive, and the two of them immediately retreated from the cave.

However, with this little episode, the faces of the two of them were much tighter than when they came in before, the two of them didn't stop, and then walked down, and soon Lin Meng saw another hole not far below, this time the two didn't stop, and walked straight in.

"Shhh

In the cave were two large metal cages the size of a house, each of which contained a huge creature, but they had long since died, leaving only a complete skeleton, and it is unknown whether they were killed by the owner of the laboratory, or whether they had been starved to death for countless years.

"What kind of creature is this?" asked Retia after a moment of careful closer observation.

"Earth, scan this creature skeleton to match the records in the database. Lin Meng commanded in his head.

"Didi, matched. The electrons that followed the earth sounded, "This is the ancient third-level creature lion scorpion." ”
