The excavation work was carried out until the early hours of the morning, but it was still far away. They also had to take advantage of the sun's weakest time of the day to rest.

In order not to interfere with each other but at the same time to ensure the safety of each other's lives, they were divided into three groups to rest in different locations in the tunnels that had been dug. Because Jiang Yue is only a mortal, two people accompany him, and the others are not restricted by activities and are freely distributed.

The little fox naturally wanted to follow Bao Yueyue, but she didn't expect Bing Bao to follow her.

"What? Is there something wrong? Bao Yueyue looked at the ice bubble beside her, lowered her head and didn't say a word, only occasionally her body shook slightly, so if you don't look closely in a dimly lit place, you will think that a piece of gravel fell to the ground.

The ice bubble body is round, and after eating, the body becomes more bulging, and it does look like a fast pebble. After squatting, Bao Yueyue still can't be level with it, and it is inevitable that there will be some inconvenience in speaking. Looking at her clothes that were already covered with mud due to digging a dark passage, there was nothing to taboo, but fortunately she lay down and chatted with Bing Bao, she couldn't sleep anyway.

"Bing Bao, do you miss your child?" Bao Yue guessed. Because whether he regarded her as a bad person before, or now he walks with them, it is to find its lost child. And this time the secret passage was discovered by it first, just now when they were digging, Bao Yueyue observed that the ice bubbles turned light green, which represented its urgency. So Bao Yueyue naturally thought that it might be that she felt the breath of a child at the bottom of the dark tunnel.

As a very sensitive demon, Ice Bubble has a strong connection with his own children, so it is not difficult to find it with the breath of a child here. It's just that if its child really stumbles into this secret passage by mistake, it can still feel how strong its sensitivity is. Bao Yueyue was still curious about this, so she took the initiative to mention it.

It's just that Bing Bao actually cried after hearing Bao Yueyue's words, and the tears seeped into the soil when they fell on the ground, and combined into beads. These beads are like miniature versions of Saturn, with rings around them, but they don't rotate, they're just there.

"This ...... This is the soil fixing technique of hardware! How is this possible!? When the little fox saw this, he cried out loudly, and realized that everyone else had fallen asleep, and quickly covered his mouth, but still squeaked.

Bao Yueyue set up an enchantment around them, although it is not as calm as the one that is calm, but it can also play a certain sound insulation effect. "You can just talk quietly and don't worry about disturbing them."

"What kind of consciousness did you just talk about?" Bao Yueyue had never heard of this kind of spell. Or is it just a trick...... No—the little fox had surprised them too much, and even he was surprised, so it must not be underestimated.

"This soil fixing technique is only one of the hardware techniques, and there are four kinds of alchemy, wood-making techniques, water cutting techniques, and static fire skills. Although this earth fixing technique is the last in the ranking and the weakest demon art, it is still included in the ancient strange book, and it has been lost for hundreds of years, and I will see it today, it is really ...... It's incredible! The little fox hurriedly took out a few leaves from his bag, looking for something inside?

"The Book of Ancient Odds!?" This kind of saying is even more unheard of. However, the names of the five types of hexology directly and clearly point out their respective functions. Fortunately, these are just witchcraft, otherwise if humans can also cultivate, those crooked demons who want to turn stones into gold and make a fortune and have other ideas will be hollowed out.

"These maple leaf papers were left to me by my grandfather, and they recorded these five ancient witchcraft in detail, but it also stated that the last generation of their descendants had passed away. So ice soak it...... Have you lived for more than a thousand years? "If you want to cultivate the ancient demon arts, it will take at least nine hundred and ninety-nine years, and even if you are the best candidate with extraordinary talents, you will have to cultivate for at least eight hundred years. And the ancient magic has been extinct for at least two thousand years.

For demons, the most important thing is time, so they have more opportunities to become immortals, and it is difficult for humans to achieve enlightenment in a short lifespan of less than a hundred years.

"In this way, the ice bubble is two thousand years old, to say the least." Thinking that she called herself a sister in front of it, which was a thousand years older than herself, and several times a day, Bao Yueyue immediately thought of a group of dinosaurs around her when she was practicing, and she couldn't help but shake her head, it was extremely scary to think about it.

"No matter how old it is now, it's an indisputable fact that it knows how to use soil fixing. This is both a great challenge for us. After reading the detailed discussion on the maple leaf paper, the little fox's face became very bad "According to historical records, if you can get any of these five elements, you can shock one side, and if you can get all the five elements, you can completely change a world." ”

"Change the world?" Bao Yueyue looked at him suspiciously. The always optimistic and positive little fox will also have anxious times? She couldn't understand both of them anymore. The little fox is always able to pull out a lot of objects that he has never seen before, and can play a huge role in critical moments, and the secrets of the ice bubble are even more. Because he was born in this other universe that is completely independent of the galaxy where the Earth is located, and follows different laws of time and space, it is naturally very different from those youkai who live on the Earth. In addition to using spiritual power and ordinary demon arts, the level of human intelligence is much higher than that of ordinary monsters, and the ancient demon art of soil fixing just now has been used, which is enough to prove this. Therefore, the current ice bubble is becoming more and more like a restless virus, and many aspects of the ability are hidden in the shadows, and no one knows when it will be stimulated. Coupled with the fact that its mood changes greatly, who knows that the next moment it will see them as enemies.

However, without definite evidence, no one can make judgments, let alone discuss right and wrong, which will affect the sense of trust between each other. This principle is not only applicable to human society, but also the demon and blood clans have lived under such rules for thousands of years.

The little fox knows that changing the world is not something that can be done by one person, so to be precise, the ice bubble is likely to become the fuse of change. "Ice bubbles are not aware of this ability of their own, and it is activated naturally by sadness. Just because we're just a few of us here doesn't mean there aren't anybody, although there may only be one or two exceptions. But if they also encounter ice bubbles and find them, they will inevitably be curious. And in this world, I will not be the only one who knows that there is ancient witchcraft, and my grandfather, who has passed away, is likely to have more trouble in the future. That's exactly what the little fox was worried about. He is very optimistic every day, and he is calm beyond his years in everything he does, because there is room for maneuver in those things, and as long as he racks his brains, there will definitely be a way out. But now this unprecedented discovery is different.

The reason why the ancient demon magic disappeared was that in addition to the objective factor of the successive deaths of the heirs, it was more due to the manipulation of human subjective factors. Because these five kinds of demonic arts are too powerful, they can't completely control both good and evil. And if either side has it, the blow to the other is devastating. Therefore, no matter how powerful this demon is, neither side dares to use it. Sometimes, a lot of the trouble you get around you is because you have it and he doesn't. So in order to break this situation, the ancient magic has fortunately become a taboo that everyone avoids talking about, and over time, it disappeared from the public.

Now, the ancient magic has reappeared, and it is found in such an artificially created world that does not apply traditional rules and regulations, and it is bound to gradually bring those who have plans to the surface. Therefore, it is uncertain what the benefits of this discovery will be for their group, but it is certain that they will have to face many problems in the future.

"Little fox, do you want to tell calm about this matter?!" It was rare for Bao Yueyue to see him at such a moment, so she was stunned for a moment, but she still came back to her senses as soon as possible. Since this matter is doing more harm than good for now, it is necessary to prevent it from happening.
