The door opened silently, and it was pitch black behind the door. With the faint glow of luminous moss on the fissure rock wall outside, a small area near the doorway could be seen vaguely. Sure enough, the ground and walls inside the door are also made of metal, but unlike the outside, the metal inside is set to a light blue, which is not as dazzling as the silver-white outside, which is more suitable for creatures to live inside for a long time.

"Let's go in and have a look. Pannis turned the lamp back on, pinned it to his arm, and beckoned to Lina. Lina nodded, and followed Pannis into the door.

After taking a few steps forward, the metal gate closed silently behind the two of them, and at the same time, the metal roof suddenly emitted a soft light, illuminating the surroundings. It was a deep corridor that stretched forward little by little in the line of sight of the two as the roof light lit up, until it reached the end of the corner a few hundred meters away. The hallway was all metal, and there was not a single door on either side, just a straight road leading to the front.

"Huh?" Lina was startled by the sudden light on, let out a short exclamation, and turned her head to look around: "This thing is also automatic?"

"It should be. Pannis could only turn off the Crystal Lamp again, but he didn't take it off his arm, and walked forward with the Crystal Lamp: "I still remember that in the Weeping Cave, Vivien was very surprised that the equipment in the institute would still work in six or seven hundred years, and then look at the equipment here, tsk." ”

"Be careful when you say that, Vivien cries to you. Lina covered her mouth and smiled evilly and said, "But it's really incredible here, how can the equipment still work normally?"

"Who knows, there are too many things about goblin technology that are incomprehensible to the lives of the Tertiary and Quaternary Ages, including the few goblins that survived. Pannis shook his head and sighed, "Let's go, see what's inside." ”

Walking along the metal corridor, only the footsteps of two people echoed in the corridor, and the slight footsteps were extremely clear and monotonous in the dead silence. The corridor is not high, only about two and a half meters, with the height of Pannis, you can almost touch the roof with your straight arms, this is because the height of goblins is much lower than that of humans, with an average of only about one meter and four, so humans often feel very uncomfortable when they walk into the buildings of the goblin era, and even occasionally some humans who are exaggerated to the point of being tall, and they need to keep their heads down if they want to walk into the goblin building.

Of course, neither Pannis nor Lina are as tall as that, and they still belong to the category of normal people, so the two of them are walking in the corridor quite normally, except for feeling that the space is slightly oppressive, there is no other abnormal feeling. After walking for a few minutes, the two came to the corner at the end of the hallway, and when they turned the corner, they saw another metal door in front of them. I thought it would take a lot of effort to open the door, but I didn't expect that as soon as Pannis stood in front of the door, the door simply opened automatically.

"Is this door automatic in both directions?" asked Lina.

"Not necessarily, you go inside, I'll step back and close the door and you stand in front of the door from the inside, see if it can be opened over there, if the door doesn't open after half a minute, I'll open it from the outside." After Pannis finished speaking, he waited for Lina to enter the door and let the door close automatically, and it didn't take long for the door to open automatically, Lina stood in front of the door and said, "It seems that this is a two-way street." ”

"Come and see this. Pannis said as he stood outside the door.

"Huh, a button?" Lina looked in the direction of Pannis's finger, "There's still a word on it, well, it's just a goblin script, I can't read it at all." Do you know what's the use of this?"

"I don't know. I know some goblin script, but I can't read it either, it's not an ordinary goblin script, it's a ciphertext from the ancient goblin empire, and there are no more than three creatures in the world that can understand it. Pannis said regretfully: "However, looking at the position of the button, I guess it should be a manual control of the door to lock the door, you step back a little, I will press it and try it, the button placed in such an obvious place will definitely not be a dangerous thing, otherwise it is no different from murder." ”

Press the button, stand in front of the gate again, and sure enough, as Panis guessed, the gate no longer opens, and press it again, and the gate opens automatically.

"It's so fun. Lina pushed Pannis aside, played with herself a few times, and said with a grin: "Why can't this device be used now? ”

"It takes a lot of energy to maintain each pressure sensor, and the bigger the building, the more rooms there are, the more pressure sensors are needed, and no one can afford to consume that hugely, and it's a needless exertion. Pannis explained: "But the goblins are not afraid, it is said that during their most prosperous period, they can drive the energy drawer directly into the depths of four or five thousand meters underground, and draw energy directly from the underground hedron layer, without having to mine the hedron close to the ground like in our era." ”

Lina listened, a little leisurely: "When will our civilization develop to that point?" ”

"If the creatures of this era don't do something to find death on their own, maybe another one or two thousand years will do. Pannis said nonchalantly, "It's not a matter of now, don't be stunned, let's go." Oh my God, I know where those monsters came from. ”

"How...... Finish. Lina then turned around, stuck in her throat for half of her words, and stayed for a long time before continuing: "Well, I think I know too, what the hell is this. ”

Behind the door was a huge rectangular room, a hundred meters long and more than ten meters wide and high. The rectangular room is not empty, but rather crowded, and the key lies in the items placed on the left and right sides of the room. In the middle of the room, there is a two-meter-wide passage connecting the front and back, and on the left and right sides of the passage, there are symmetrical pairs of crystal jars up to five meters high, there are fifty or sixty ...... The bottom of the jar is metal, touching the ground, so that the structure inside cannot be seen, and it is made of transparent crystals except for the metal base. The four crystal jars closest to the gate were broken, and the rest were still intact. The crystal jar was filled with a translucent liquid, and the liquid was soaked in hideous demonic beasts. Obviously, the four broken crystal jars at the door were the dwellings of the four earth hunters.

"Wait. Seeing that Pannis was about to move forward, Lina grabbed Pannis suddenly, her forehead was covered with cold sweat, and her voice was extremely low: "I suddenly thought of a question, will these dozens of demonic beasts still be alive in this." ”

"I don't think any of these monsters can live for nearly 10,000 years. Pannis shook his head violently.

"But, how do you explain the four Earth Hunters?" Lina swallowed and said in a dry voice, "Obviously, those four Earth Hunters got out of here alive. And if you look at the crystal shards on the ground, the fractures are obviously new. I feel more and more that what I think is right, the monsters here are still alive, but they have been soaked in these jars and fallen into a dormant state, so they can survive nearly 10,000 years. ”

"Maybe. Pannis nodded: "Well, I understand the button outside, just in case." But it's clear that the goblins think it's absolutely safe, so they don't even lock the door under normal circumstances. This means that these monsters will not wake up on their own. ”

Lina silently pointed to the debris on the ground: "There are four here that disagree with you. ”

"I'm afraid there was only one, and then it broke the jar from the outside and woke up the other three of its kind. "Otherwise, it wouldn't have been so coincidental that four identical creatures woke up at the same time," said Pannis. Presumably, the jar soaked in it malfunctioned, which caused such a result. ”

"Maybe. Lina nodded in approval of Pannis's idea, "But it still feels dangerous." ”

"Shall we seal the door and leave?" said Pannis.

"No, I can't. Lina shouted to stop, then immediately covered her mouth, held her breath, and after a long time did not hear any movement, she continued to whisper: "It's amazing here, I ...... I'm going to have to take a look. ”

"Tsk, hell curiosity. Pannis said helplessly: "Then what are you waiting for, let's go." ”

The two of them moved forward very cautiously little by little, as if they were facing a great enemy, and slowly approached the first crystal jar that was not broken. If you get close to the crystal jar, you can see the creatures soaked inside. In the jar, a tiger creature that stands on all fours and is more than 1.5 meters tall floats in the liquid, and between the tiger's front and rear legs, there are bat-like webbed wings.

"It's ...... Tigers?" asked Lina, uncertain.

"I guess so, a creature that's long gone. Pannis wasn't quite sure: "You've heard of it?"

"The benefit of reading a lot, that's the power of knowledge, you don't understand. Lina stared at the mantat in the jar and felt as if it would open its eyes at any moment: "It really won't wake up." ”

"Knock knock. Pannis knocked the jar a few times and shrugged at Lina's eyes that wanted to strangle her, "You see, I shouldn't wake up." ”

"Why don't you go and crash to death, it almost scared me to death. Lina gritted her teeth and glared at Pannis for a long time before moving to the next jar.

"Tooth Split?" Lina asked.

"Yes, the kind that doesn't weave webs, and hunts by speed and latent ability. Pannis nodded.

"I hate this kind of thing. Lina grinned, clasped her hands, and rubbed her arms: "How can it be so big, this height is one meter." ”

"Who knows why. Pannis, apparently not a fan of bugs, said in disgust, "If you don't like it, go to the next one." ”

"It's a butterfly. This time Lina didn't use a question.

"Well, if they are reduced by dozens of times, that's what they are generally called. Pannis pointed to the wings of the giant butterfly: "Look at the edge, with the texture of metal, I'm afraid it's not a good sign." ”

"It's disgusting, this is a crypt worm, I've never seen it before. ”

"And this, the dragon-scaled wolf? This one has long been extinct. Where did the goblins get the extinct monsters? ”

"I have to warn you that this is a building that is close to ten thousand years old. ”

"Oh, yes, I forgot. ”

The two of them watched and commented on it, and walked all the way to the door at the end of the passageway, and Lina stopped unsatisfied: "Fifty jars, no, counting the broken ones, fifty-four jars, seventeen kinds of creatures, it's quite interesting." ”
