Subsequently, they groped for the chassis, and found a copper tongue from the position of the chassis, after opening the copper tongue, it was a square copper plate that opened outward, and because it was completely sealed, there was not much dust, but a layer of floating ash, and it did not delay the effort.

Yue Guanchao picked up the flashlight, and took this opportunity to observe the structure of the chassis for them, he always thought that the chassis below was a solid poured metal disc, which could be used to counterweight to support the weight of metal balls and metal rings.

At the bottom of the chassis, there are many bowl-sized copper bowls, which are assembled into a hexagonal shape, completely covering the bottom of the copper plate, forming a honeycomb-like structure, each honeycomb copper bowl has a finger-thick wick pillar, one inch higher than the entire bowl mouth, and the pillar is wound with a wick material rope.

Looking at the burnt marks, it was most likely that they had been burned, and when he looked at the copper cup, he had already seen that the ointment had not yet completely evaporated, and the pale yellow lard was completely solidified, as if a candle with a thick bowl mouth had been placed in these lamps.

After talking about the ground layer of the chassis, let's talk about the four walls of the chassis, the most common thing here is the bronze mirror that has been plated with silver.

The height of these copper mirrors is the same as the height of the chassis, and the width is also close to half a meter, forming a copper mirror slightly larger than the lid of the pot, and these copper mirrors are slightly protruding from the four walls of the chassis, connecting with each other, completely covering the inner wall of the site.

All of these structures come around the central support bar, and you can see that the support bar is a hollow structure, connected to the chassis, and then there is nothing left.

Yue Guanchao asked, "How do you use this thing?"

Gu Xixi took out the fire fold in his hand and lit one of the wicks, the wick flames jumped, gradually regained stability, and bloomed with bright and extinguished light, and then, the flames flowed along the pillar to the other wicks, but between breaths, he had already seen all the flames in the chassis being lit.

A large number of candles illuminated the entire chassis interior, and no longer saw the darkness and chaos just now, and every part could be seen clearly.

In this process, the light of the flame is constantly refracted by the surrounding mirrors, reflected, and reflected, and extremely bright light spots begin to appear, as if a sun is thrown into the chassis, and the resulting light emits countless rays in an instant, and these rays and light spots are implicated in each other and bite each other, and in the design of the light structure, it is completely concentrated in the hollow tube where the struts are located.

The situation of the candle flame has been shown to be affected by the mirror optical effect, forming a blazing white light as bright as the sun inside the chassis, which has completely exceeded the brightness of the candle flame, only at this moment, the crystal ball in the middle of the illusion is completely lit, as if a sudden sun, appearing in the dark tower.

Their eyes are accustomed to the dark environment, and the sudden stimulation of this strong light is like being punched in front of the door, and they are weeping and sore, until they put on the sunglasses they have prepared, and they can be completely restored to normal.

"That's too bright, isn't it?" After Song Siyuan put on her sunglasses, the soreness around her eye sockets disappeared, which showed how dazzling the light bloomed in the crystal ball.

Gu Xixi retorted: "The purpose of the illusion is to create a huge illusion for thousands of people to see, and the brightness of the candle flame must be the highest, without these brightness, it is impossible for many people to see the common illusion."

As they spoke, a rumbling sound began to be heard under the floor around them, as if some mechanism had been touched, and they saw that the window lattices outside the eaves of the nine-story tower all opened automatically, and through the windows, they quickly shone out in all directions of the mandala, as if a high-brightness lighthouse appeared in the city, illuminating the mandala as bright as day.

Yue Guanchao took this opportunity to walk into the window, looking at the outside world through the windowsill, the original dark and chaotic world gradually receded into darkness, and the Sand Sea King City began to lift the dark veil and reveal its original appearance in front of people, this feeling was as if the black and white photos they saw were gradually recovering color, and the details of palaces and temples, pavilions, residential mansions, commercial streets, gardens, river pools, bridges and towers in the city began to be enriched in the light, and they were no longer gray and black horrors seen without light sources.

"Other temples seem to have this kind of illusion, and I seem to see the top floors of other golden pagodas

It's also glowing."

When Yue Guanchao observed the outside world, it was easy to see that all the temples from the inside to the outside were glowing, and if you looked closely, the light was coming from the golden dome floating in the temple, but after all, the specifications of these temples were smaller, and the light emitted was of course not as good as the tall floating temple in the center, in any case, one thing was completely certain, judging from the structure and arrangement of the temple, these lights were centered on the tall tower where they were located, and they were constantly blooming brightly.

Gu Xixi noticed the strangeness of the current situation, and walked to the windowsill with him, carefully observing the layout of these lights, and sure enough, the tower they were located in was centered on the inner and outer cities and the temples on the city walls, forming a lighting pattern of stars and moons.

It can even be seen that the golden light emitted from this gold-domed floating slaughter completely falls on all the small gold-domed towers, inspiring endless golden light, and the common brightness also completely dispelles the last trace of darkness in the sinkhole.

The entire city has been dyed from black, white and gray to bright colors, restoring the gorgeous and extravagant Shanshan Imperial City of a thousand years ago, if you want to accurately describe it, it is like a sleeping withered corpse gradually taking on a soul and body, and glowing with new brilliance again.

"How can these other towers light up?" Yue Guanchao was excited, but also curious about the situation in front of him.

Gu Xixi observed the surrounding situation, nodded at him and said, "The rumbling sound we heard just now is the mechanism that we activated the illusion instrument, judging from the rules of these arrangements, it seems that all the temple towers have illusion instruments, and the rotation of those mechanisms may trigger the mechanisms of other towers, causing the joint reaction of these temple towers, and it is not surprising that this situation is not surprising."

"Now, it's up to us what we can find out from the illusion."

After Gu Baiyue finished speaking, she walked back to the vicinity of the illusion instrument, and two ball-like rockers had floated on the chassis, Gu Baiyue put her hands on the two copper balls, and she could directly rotate the two copper balls, and at the same time, the metal ring also began to rumble and rotate on the tray.

As Gu Baiyue manipulated the copper ball, the metal ring began to rotate back and forth along the central copper axis, and the totem pattern in the crystal ball began to be refracted by the mask of the metal circle, and gradually appeared above the top of the tower.

The last illusion that appeared before the destruction of the Sand Sea King City, along with the entire city, became a mirage and began to slowly appear in front of everyone.
