Feng Yiting stood silently in the void, motionless.

He understood that this place was called "Chiba Castle", and these guards should be the outer guards of this castle.

At this time, he watched as the guards used that magic wand to poke around the gate.

Feng Yiting took a serious look at the group of guards, only to find that the leader was holding the magic staff, and there was a guard behind him who was holding a huge crystal and staring at the crystal motionlessly.

In this case, the wand and crystal should be a set of sensing or display terminals.

If you don't guess wrong, the staff detects an anomaly and it will show it on the crystal.

Feng Yiting remained motionless, and at this time he restrained any traces he might reveal, for fear that the other party would probe out of him.

Slowly, I saw the guard groping towards him, and the leader carefully held the staff, poking east and west, as if looking for the devil hidden in the void.

The kid was tentative, and at the same time asked, "Is there anything abnormal? Is there anything abnormal?"

The crystal holder shook his head again and again, and he muttered, "I didn't find any anomalous chiefs, huh...... There seem to be some traces of energy loss in this place, yes, it seems that there is energy disappearing in this area, hey, it's weird, and now it's normal again. ”

Feng Yiting understood that he had converged too much just now, because he had excessively converged his energy, which directly led to the negative expenditure of energy, which made the other party detect the abnormality.

Fortunately, he made adjustments in time, and he was able to get by.

Hear the muttering in the back. The guy then continued to poke the little staff around where Feng Yiting was staying, and did not stop until the crystal had no more abnormalities, still standing in the same place. Looking around, he muttered: "It's strange, there was a clear alarm just now, and I will only inform the chief, how can there be no movement now?"

Feng Yiting saw him stop, but he didn't bother to entangle with them at this time, and after hiding himself, he floated towards the interior of the castle.

After he walked in the door. I heard the guard at the door suddenly scream: "Hey, there was another fluctuation sir, and there was another fluctuation on the crystal just now, sir, you see...... Gee, this is going to be fine again, what's going on?"

The guards were flustered again. Everyone searched around, staring at the crystal ball at a loss.

At that time, Feng Yiting had already infiltrated the castle, and he found out. In front of you is a large and spacious hall.

It's like a huge cave. The middle was empty, and then the four walls of the castle were filled with houses.

In this way, the light above the head can normally pass through the deliberately set aside space, and then spread throughout the castle, and finally every house built within the castle can share the light.

The castle is like a collection center of stacked houses, and countless houses are stacked on top of each other to form the walls of the entire huge castle and other main structures, which are integrated with each other. The result was a huge and magnificent castle.

Just below the castle, the widest place is the most concentrated and lively market in the castle.

There are a variety of shops here. There's a lot of everything. The various types of shops are divided into different areas, organized and orderly, and the operators are all sincere and respectful to provide various services to the residents of the castle.

Feng Yiting noticed that there are also lighting facilities in these towns, but these lighting supplies, in addition to some large light bulbs that can be driven by lamps, are more like prism-like refractive devices.

After a little scrutiny, he understood that these refracted mirrors could be refracted through some fixed large-scale refraction sources, through layers of lenses, and finally obtain light from afar.

Of course, in the end, these refractive prisms will project light onto some specific reflective devices, and through this terminal, they will diffuse to make a certain area light.

Feng Yiting understood that it was still daylight, so these lighting facilities were not activated.

As long as you adjust the refraction angle of one of the lenses, you can achieve the effect of switching refraction, which is simple and easy to use, and the most important thing is environmental protection.

Speaking of environmental protection, Feng Yiting noticed that in this castle, it basically relies on natural wind energy, or other non-motorized kinetic energy, such as a large windmill at the top of the castle, which is estimated to provide some kind of natural energy.

Of course, it is not absolutely impossible to use mechanical kinetic energy in the city, for example, there are some very modern devices, but they should be idle for a long time, and maybe only on some special days.

Moreover, the middle position of this castle was obviously a huge launch device, and Feng Yiting understood that if this position catapulted something like a rocket or missile into the sky, it could be launched from the middle of the castle.

As such, this thing is supposed to be a flying machine with great mechanical energy, but it is heavily concealed and does not look like it is used regularly.

Looking at this huge castle, in addition to the primitive and quaint, stepped walking stairs that extend upwards around the inner walls of the castle, there is also a kind of semi-automatic elevator of different sizes for people to use.

This is a special type of elevator that varies in size due to the need for use, and passengers can choose to ride.

These are lifting devices that need to be manually driven, and young men and women will take the initiative to go to the artificial power position in the elevator, step on those pedals similar to bicycles, and then obtain kinetic energy.

This artificially acquired kinetic energy can drive these semi-automatic ladders that can be raised.

These ladders have been specifically designed and streamlined, so you can get the most momentum with less effort.

Of course, generally speaking, it is only used when ascending, and when descending, because of gravity, as long as the speed is controlled.

In short, what was in front of him made Feng Yiting quickly understand the purpose of the dungeon's energy use.

To sum up, it should be able to save, not to save as much as possible, but not to solve the problem with manpower, the final production will still use machinery or other energy.

He knows very well that this world is not without advanced technology, but human beings will be extremely restrained, trying not to allow themselves to use those devices that can save people's effort. They respect nature and abide by nature, and everything is based on obeying the natural environment.

Compared with the earthlings, the residents of the dungeon undoubtedly cherish and understand their world more.

This kind of theme touched Feng Yiting quite a lot, and he suddenly admired these mysterious creatures hiding underground.

The castle was full of people, and they were all about the same size as the people on the surface, the only difference was that each of them had extremely fair skin. This is a soft but not pale whiteness, apparently because it has never experienced strong ultraviolet radiation, and this jade-like whiteness makes these mysterious underground people look sacred and noble, and it is awe-inspiring.

Feng Yiting took advantage of the fact that others were not paying attention, he found a secluded place, and also turned into an ordinary underground city human, he began to wander among these underground humans, looking around.

Feng Yiting looked around, visited the market in the castle, and began to look at the architectural structure of this huge castle.

The castle is made of some huge strips of stone.

These giant stone bars are stacked closely with each other with their own volume and weight, so they obtain a solid architectural effect, far stronger than the pyramids on the earth's surface.

Sure enough, as he had initially suspected, the castle merged with the mountain.

It's a kind of architecture that complements each other. It is estimated that when they were digging the mountain, they used the stones taken out of the mountain to build the castle, and finally built such a huge magical castle.

Feng Yiting sighed with emotion, after his observation, he knew that these inhabitants would not destroy the earth world at all, and it was their king Gunira who could affect the surface of the earth.

Thinking of this, Feng Yiting sighed softly.

He finally gave up trying to wreak havoc in the underworld and slowly walked towards the exit.

A boy shook his mother's arm, and he said innocently and curiously, "Mom, Mom, I saw a brother walking, and he disappeared into thin air! Mom, is he the devil?"

The mother looked up curiously and stared at the place where the child was staring.

After discovering that there was nothing there, she smiled and told her child: "You are wrong baby, there will be no devils in Chiba City, our great king Gunila and the eight brave guardian demon gods will never allow any demons to enter the dungeon, go to your father, child, he is calling you!"

The child blinked his flawless eyes, began to believe her mother's words, and ran away for his father.

She would never have known that the child had indeed seen a powerful monk who was powerful enough to destroy this world, and no matter what method Feng Yiting used, he could turn this mysterious and peaceful dungeon upside down in an instant, even destroy it.

But he wouldn't, he smiled and looked at the child who was running towards his father in the distance, and was suddenly very moved.

Feng Yiting suddenly felt the urge to shed tears...... Sometimes, a continuation of the plain is the hallmark of the world, just like this mother, and her children and husband.

This paradise hidden deep underground, they have no quarrel with the world, how can it not be another beautiful world.

After Feng Yiting left Chiba Castle, he once again evaded the exploration of the guards, and then took off into the air, heading towards the exit hidden in the high firmament of the underground world, he didn't want to affect the inhabitants here, so he could only go out to find Gunira.

However, can he find these demon gods who are powerful and want to harness the energy of the huge eruption of the Yellowstone volcano......?
