Cha Wenbin took the bronze lump in his hand, ready to put it back in his bag. Just as he opened the mouth of the package and was about to send the bronze wheel inside, a extremely bright point suddenly flashed up, its brightness comparable to that of diamonds.

  But the bright light was fleeting, and it returned to its usual dull appearance. The word "meteor" even flashed through Zhang Wenbin's mind.

  "Huh?" He muttered to himself, looking left and right, but there was nothing special, yet he had indeed seen it just now, and Old Wang also said it was shining.

  "Lao Wang, it's really bright, I saw it," Cha Wenbin said.

  Old Wang immediately opened his eyes and moved to Cao Wenbin's side, shouting: "Where is it bright? Where?"

  "This thing seems to be glowing in rhythm, not always on. Wen Bin touched his head and said: "Now it's gone again, like a meteor flashing by, white light, really strange, how did I not notice it before?"

  Then the two of them simply put that thing on their legs, staring at it intently, and from the interval between the last two glows, it was only a matter of time before the next one came.

  Many things are like this. When you want to get it, you will never get it. On the contrary, it will appear unexpectedly. A whole hour has passed and the two of them have been taking turns blinking, afraid of missing something.

  But the reality was cruel, Cha Wenbin felt his eyes were sour: "Alright, let's not look at each other anymore, looking again is just a piece of copper plate, it will shine when it should shine, we'll talk about it later."

  Old Wang still felt a bit unwilling. He always thought this thing was not simple. "Let's wait a little longer, anyway we haven't arrived yet."

  Cha Wenbin suddenly felt that it wasn't like this, first of all, this thing was made of bronze and didn't have the material needed to emit light. In nature, things that can emit light on their own are only phosphorescent stones or night pearls, but except for these, they all have continuous luminescence. Only phosphorus fire can possibly produce such dazzling light in an extremely short time. Does this contain phosphorus?

  A piece of bronze that has been around for ages, even if it contains phosphorus, should have been consumed by the air after all these years. What could still be glowing?

  The two of them started thinking about this issue and excluded all kinds of possibilities one by one. What else could be done like this?

  Old Wang thought: "Natural luminous bodies such as glowstones need a light source to shine for a long time and absorb the energy of light before they can emit light themselves, but this is obviously not the case. Wen Bin, I think we still need to change our perspective and not just look at it from the material aspect."

  So, aside from natural luminescence, what other ways can it emit light? Wen Canbin pondered for a moment, then suddenly he exclaimed as if waking up from a dream: "Mirrors! Old Wang, have you ever thought that maybe it's not emitting its own light, but rather reflecting it?"

  "Reflection? Right, it's not impossible, let's try it quickly."

  Cha Wenbin treated the bronze wheel as a mirror and placed it under the sunlight, but there was no reaction at all. It seemed that this inference was about to be overturned.

  "Let me think again," said Zhang Wenbin, "We call it the Sun Wheel because of its shape, especially those five rays that are vivid and lifelike. If it's the sun, then it should emit light, so the light should come from this small circle in the middle. What about this outer ring?" He looked at the Sun Wheel in his hand and suddenly thought of that circle again.

  If we say that the circle is both infinite and chaotic, it is the initial state of the universe. Then this sun wheel, with the sun in the middle position, surrounded by five bronze rods connected to the outermost layer of the circle, can it be understood as the sun being at the center of the universe?

  For the ancient people's view of the universe, such an understanding is already quite rare.

  Cha Wenbin took the thing and looked at it repeatedly under the sun, Old Wang said: "Could it be an angle problem?"

  "Angle?"

  "What if it can only reflect at a certain special angle?"

  Zha Wenbin carefully held it, moving slowly up and down in the sunlight, allowing each angle of the sun wheel to be directly illuminated by the sun. As he turned it like this, when Zha Wenbin's bronze sun wheel reached a tilted position, a burst of extremely bright white light suddenly flashed. Old Wang and he both opened their mouths wide, it was unbelievable.

  This flash was also fleeting, and after knowing the general angle, Zha Wenbin made fine adjustments again, slowly retreating a little bit, and a stream of light suddenly appeared on it, like a lighthouse shining on a reef in the dark, so white, so bright.

  "It really is relying on reflection!" Zhang Wenbin said. In the next few tests, they found that only one angle could reflect this light, and it was extremely difficult to determine, often just after adjusting the angle, it would disappear again. This is an extremely subtle thing, even due to human breathing and pulse beating can make it deviate.

  Old Wang was marveling at the ingenuity of the ancients while recalling what that person had said: "This is a living thing." "If it were just an ordinary ritual vessel or symbolic object, it wouldn't be so complex. This craftsmanship is not something that even modern artisans could achieve, let alone people three thousand years ago."

  Because humans move, boats also move, and even the earth is moving, so Zhang Wenbin was unable to capture continuous reflections. After a few attempts, he gave up and put it back in his bag.

  Old Wang laughed and said: "Wen Bin, this treasure is too precious, you'd better keep it close to your body, putting it in that tattered cloth bag of yours isn't safe."

  Cha Wenbin looked down at the octagonal bag with patches, which was left by his master. He thought about it and decided to take it out and put it in his chest pocket. This kind of horseback riding coat had a design similar to a pouch inside, specifically for carrying personal items.

  "Wenbin brother, we're almost there," Chaozi shouted, "it's that bamboo forest ahead."

  He hastily got up from his lying posture, and indeed, he immediately arrived. A patch of emerald green bamboo forest was right in front of him. The wind blew by, making a "rustling" sound.

  At a place still several dozen meters away, Cha Wenbin had them stop.

  "Once ashore, first, don't get scattered; second, don't be distracted while doing things; third, start eating to replenish energy now."

  Chaozi munched on the sauce beef while praising, "Uncle Wang's arrangements are really thoughtful. I recall when you took me to the wilderness for archaeological exploration, why did we only get to eat dry rice balls back then?"

  Everyone burst into loud laughter, and the joyful atmosphere also swept away the previous gloom. Yes, they needed such joy too much, even if it was just for a few short minutes.

  When the kayak landed on the shore, everyone was stunned. Is this still a bamboo raft?

  "What kind of bamboo is this? I've never seen it before." Zhang Wenbin stared at the lush green bamboo forest in front of him, his eyes wide with surprise. The bamboo here was not the usual cylindrical shape, but was square and much thicker than ordinary bamboo, each one looking like a wooden stake stuck in the ground.

  A group of people gathered their gear and prepared to head inside.

  The bamboo here is not only large, but also tall, with dark green bamboo leaves layered on top of each other. Although the outside was a big sun in the sky, as soon as they entered the bamboo forest, it was completely blocked by the upper layer of bamboo leaves, and occasionally a few rays of light would leak through and sprinkle on the ground, mottled and uneven. Under the blowing wind, these mottled sunlight also kept changing positions, adding a bit of eerie atmosphere to this originally solemn and unyielding bamboo forest.

  Everyone took out their flashlights and since there was no direction in here, they still had to rely on Wen Bin's compass to determine the general position they wanted to go.

  "Be careful, everyone," warned Zha Wenbin. "We don't know if there are any ferocious beasts or poisonous insects here. When we walk, pay attention to where you step, the bamboo leaves can easily cover up holes and uneven ground."

  Their footsteps trampled on the soft bamboo leaves, making a crisp "ga ga" sound. Zhang Wenbin kept looking at the compass needle, calling out to them where to go.

  "Hold on!" Chaozi shouted from behind him, "Look, there's a dead man hanging over there!"

  Everyone looked up and saw a white thing hanging in mid-air on a nearby bamboo...
