After pressing a certain spot in a corner of the control room, the ground silently split open, revealing a passageway extending downward. It was impossible to see how long it was. Only some dim lights could be seen flickering in the distance.

  "Follow me."

  Meteorite Crystal was the first to fly into the passageway, and Chen Yue and the others quickly followed.

  Chen Yue wasn't afraid that she would play tricks. During the previous exchanges, he had already gained a certain understanding of her character. Meteorite Crystal was definitely not good at disguising or lying. Otherwise, Chen Yue wouldn't have discovered the trap in the maze and found this place.

  After walking for a while, it felt like they had gone several kilometers underground. Then the passageway became level, indicating that they had reached a certain depth. At such a deep place, there was no sense of stuffiness at all. The air was as fresh as it was outside. There were also dim lights on both sides of the passageway, so it wasn't pitch black.

  "Clap, clap." Meteorite Crystal suddenly clapped her hands quickly a few times. Suddenly, the passageway was brightly lit. Two long metal cables were embedded above the passageway, with some complex patterns drawn on them. At this time, they were emitting a soft light.

  "The energy in the ruins is insufficient. Usually, these magic optical cables won't be turned on. But since you're here for the first time, Father taught me that I must treat guests sincerely, so I'm doing this." Seeing Chen Yue's confusion, Meteorite Crystal explained.

  "What kind of energy do you use?" Chen Yue asked curiously.

  "It's crystals. But only light crystals are needed. Pure energy crystals can also be used." Meteorite Crystal explained with a bit of annoyance. "Light crystals aren't naturally formed. They are made by collecting sunlight and heat energy and fusing them together. However, this technology has long been lost. The purification technology for energy crystals is the same. Otherwise, if the ruins had enough energy, I wouldn't be so passive."

  Chen Yue shook his head. He hadn't heard of light crystals before, but he had heard of energy crystals. It was an extremely rare mineral. However, most of them contained impurities. In the current civilization, very little use is made of energy crystals. They are treated as rare treasures, with a status equivalent to that of diamonds on Earth in the previous life, and are priceless. However, it's impossible to utilize the energy inside them. Moreover, the energy in energy crystals is extremely stable in nature, not as active as the crystal cores of magical beasts. Therefore, no one uses them to make magic wands or the like.

  "What a pity." Chen Yue sighed with emotion. These treasures were being wasted. If one could master the technology of the Ganino civilization, perhaps one could monopolize the energy crystals on the entire continent. One can imagine the wealth and power contained therein.

  "Well, there are more than just your ancient ruins on the continent. Maybe there is this technology in other places, or maybe this technology has been discovered but no one can understand it and it's been shelved." After a pause, Chen Yue added, "In the future, if there's a chance, I'll help you keep an eye out. You also know that the outside world is now the world of apostles. Their power is extremely powerful, and they emerged right after the Ganino civilization. Maybe they have collections. However, I don't recognize this technology either. I'm afraid only you can identify it if you go there in person."

  Chen Yue had already told her about the situation in the outside world along the way, so Meteorite Crystal naturally knew that what Chen Yue said was quite reasonable.

  "I'll think about it again." It could be seen that Meteorite Crystal was a bit tempted, but it wasn't time for her to make a decision immediately.

  Chen Yue wasn't discouraged either. He knew very well how valuable Meteorite Crystal was. As he said before, the Apostle Association probably did have many things from the Ganino civilization, but they had been shelved because no one understood them. This was definitely the most reasonable inference. Even though Chen Yue still didn't know much about the association at this moment, he was fully confident that his inference was absolutely correct.

  However, the key to all this still lay with Meteorite Crystal. Besides a life born in the Ganino civilization like her, who else could make use of these things?

  "Take it slow. I have to persuade her somehow." Chen Yue thought to himself.

  "Ah." As if remembering something, Meteorite Crystal flew to Chen Yue's shoulder and added, "I almost forgot to say that Sister Bing really likes to eat light crystals. She also likes high-purity energy crystals."

  Her big eyes blinked: "Chen Yue, you really should put in some effort. I think Sister Blade should also like to eat them."

  "What?"

  As if hearing the most incredible thing, Chen Yue's pupils suddenly widened. It took him a long time to recover, but huge waves had already risen in his heart.

  To improve the compatibility with summoned beasts, the best way is to cater to their preferences. However, the preferences of summoned beasts are different from those of ordinary people and are completely unpredictable. Even Chen Yue had only found a clumsy way to adapt to the environment that summoned beasts liked, but the effect was minimal.

  If there was any other most effective method, it would naturally be to give summoned beasts their favorite things. Chen Yue had tried many times before. Unfortunately, the Frozen Rabbit wasn't interested at all. It even scorned the crystal cores of magical beasts, forcing him to give up this shortcut.

  But now, according to what Meteorite Crystal said, there were actually things that the Frozen Rabbit liked to eat. Moreover, if the Blade Beast also liked them, it could almost be said that this kind of crystal should be popular among most summoned beasts.

  Didn't this mean that there was a way to quickly improve the compatibility with summoned beasts?

  Thinking of this possibility, Chen Yue's lips suddenly felt a bit dry. For apostles, this information was really important.

  Support the author by searching for the original publication of this novel.

  "Really?"

  Since it was of great importance, he couldn't help but believe it.

  "You'll see." Meteorite Crystal muttered and flew into the depths of the passageway first.

  After hesitating for a moment on the spot, Chen Yue quickly followed without hesitation.

  After walking quickly for more than ten minutes, the front suddenly opened up. Meteorite Crystal led Chen Yue into a huge spherical space. As soon as they walked in, the lights in the spherical space immediately lit up, clearly illuminating this space.

  In the center of the space, a huge crystal screen with a length and width of more than ten meters was suspended. It was densely divided into countless small grids of different sizes. Each small grid had a different picture. Several optical cables extended from the crystal screen and connected to several large instruments in the space. The optical cables were constantly flashing with magical light, indicating that they were clearly in operation.

  "This is the monitoring system of the ruins. That one is the control system..." Meteorite Crystal first pointed to the giant crystal screen in the center and then pointed to one of the largest and strangest instruments.

  Chen Yue naturally couldn't understand the achievements created by this combination of technology and magic civilization. However, the giant crystal screen was based on the same principle as the monitoring systems on Earth, so he could understand it at a glance.

  "Chen Yue, let's see how those people are doing."

  Meteorite Crystal said. She gently tapped the screen with her little finger, and immediately the pictures in two small grids were enlarged, each occupying one-third of the size of the crystal screen.

  On the left picture was Poison Dragon and the others. Judging from their position, they were outside the room at the exit of the maze. However, they looked a bit hesitant, clearly having some doubts in their hearts. On the right picture was Thorne. He was just walking back and forth in a section of the maze passageway and appeared in the picture intermittently. However, looking at his expression, he was full of anxiety. Obviously, Chen Yue's long absence had made him extremely uneasy.

  "Chen Yue, look. These people must be suspicious since they didn't hear my voice all of a sudden." Pointing gently at Poison Dragon and the others with her little hand, Meteorite Crystal's little face was full of worry.

  Seeing this scene, Chen Yue had to suppress his great expectations for the light crystals for the time being and instead planned to deal with these two matters first. Thorne was okay for now. But if he didn't respond for a long time, there might also be problems. However, he should be able to be appeased temporarily. Now the most troublesome ones were Poison Dragon and the others.

  Obviously, they were already suspicious. Even if they didn't dare to be blatant about it, it was inevitable that they would have doubts in their hearts. Once these people saw through Meteorite Crystal's true situation and came back, with the strength of the four of them, it would definitely be a disaster if they really fought.

  "What should we do?"

  Meteorite Crystal asked without any confidence. Unconsciously, she had already regarded Chen Yue as the mainstay.

  "Definitely don't give them time to think. These people are all extremely experienced. Once they have time to think about it, it will be easy for them to find flaws." Chen Yue said slowly, and his tone gradually became filled with an indescribable confidence.

  "People are often blinded by greed. Once they feel that their interests will be threatened, it will affect their judgment. You continue to go up there and brag to them. You can accidentally leak a few words, saying that more people are coming later. Then pretend to accidentally reveal that the number of treasures in the ruins is limited. I guarantee that they will immediately become anxious. Then you add fuel to the fire and appropriately describe the abilities of one or two treasures. Make them as abnormal as possible. I think with all the knowledge you've learned from your father, you won't even know how to brag, right?"

  "That's easy." Encouraged by Chen Yue's words, Meteorite Crystal's confidence soared. She playfully stuck out her tongue and immediately flew out excitedly.

  "Well, although all the fifth-order members of the Shi Mie Mercenary Group are dead, no one can be sure that only those fifth-order members knew the secrets of the ancient ruins. If this accident happens, they might think in this direction." Stroking his chin, Chen Yue looked at the crystal screen with a half-smile.

  I don't know how Meteorite Crystal boasted up there. On the crystal screen, Poison Dragon and the others immediately panicked. Although no sound could be heard, from their lip movements, it could still be distinguished that their guess was that the Shi Mie Mercenary Group had revealed the news and attracted outsiders.

  Originally, according to the lies fabricated by Meteorite Crystal, the gains were already extremely risky, which had already made them extremely dissatisfied. Unexpectedly, more people were coming later, planning to share the already meager profits. How could they sit still?

  Poison Dragon was the first to curse and enter the room. He activated the teleportation device, and with a flash of white light, he disappeared immediately. With him taking the lead, the others naturally followed suit.

  "Seeking their own doom."

  Watching the four of them rush into the teleportation device one after another, looking as ugly as if they were afraid that if they were a moment slower, others would take the biggest share of the benefits, Chen Yue couldn't help but show a sneer.

  "Giggle, giggle." Meteorite Crystal flew back with a series of clear laughter. Looking at her bending over with laughter, it was obvious that she had had a great time playing tricks on those people just now.

  Finally managing to stop laughing, Meteorite Crystal, who had solved a big problem, felt much more relaxed. But when her eyes swept across the crystal screen, she immediately jumped up as if her eyebrows were on fire. She quickly took out the instrument that could change voices and urged, "Chen Yue, quickly tell that person to stop. The ice wall that I built with so much effort is almost completely demolished."

  On the crystal screen, Thorne, who had been waiting for a long time without getting a response, thought that something had happened to Chen Yue. Unable to suppress his anxious mood any longer, he vented his anger on the surrounding ice walls.

  "Can this instrument contact Thorne here?" Chen Yue asked curiously. Watching her running up and down, he had thought that she had to go upstairs to use the instrument to talk.

  "You're so close to that idiot. It'll work here." Meteorite Crystal said angrily.

  "By the way, where does your teleportation device send people to?" Before walking to the instrument, Chen Yue suddenly asked.

  "That one." Meteorite Crystal blinked her big eyes innocently. "It's a random teleportation device. I don't know where it will send people to. But it's at least a million miles away."

  Chen Yue's hand trembled when he heard this. He almost pressed the wrong button. He turned around and gave Meteorite Crystal, who looked innocent, a strange look. Sure enough, the most poisonous thing is a woman's heart...

  Calming down, he put aside his distracting thoughts, walked a little closer to the instrument, and in the next moment, Chen Yue's steady voice rang out.

  "Thorne..."
