Candles are a key clue for tomb robbers.

Oil lamps and candlesticks are common, but there are no candles in tombs that are too old.

The Egyptians began to use beeswax more than 5,000 years ago, and the Chinese nation was relatively backward, and Fang Yan's impression seemed that the detailed records of candles began to appear in the literature of the Jin Dynasty.

"Fang Yan, can you hear me?"

An old voice came out of the headphones, it was Professor Kim.

"I can hear you. Professor, is my master in the live broadcast room? ”

Fang Yan continued to touch the sensor on the headset, and as Er Zhu introduced, the ordinary barrage on the lens immediately disappeared, leaving only the "VIP barrage".

Those who can send VIP barrage and voice barrage are their own people who travel this time, while ordinary viewers need to use keyboards or projection keyboards to knock out the barrage.

"Your master went to the tomb in Gansu in the morning, and he said that the tomb is more important than this side and cannot be delayed any longer." This time it was Lin Yuanshan who spoke out.

Jin Sanshi returned to the topic: "Fang Yan, you go closer to the northwest corner, let me see what kind of candle it is." ”

Hearing this, the three of them took Erzhu as the center, cautiously moved in the northwest direction, and walked about twenty-six steps to reach the corner of the wall.

By the light of the Hydra, it is clear that this is a brick chamber tomb, and the surrounding walls are all made of blue bricks.

"Professor, this seems to be a brick tomb from the Han Dynasty. But I remember that there should have been no candles in the Han Dynasty, right? There is no burial goods nearby, there is no burial pit on the periphery, it is not like the custom of the ancient people in Qinghai, and the most important thing is that there is no coffin here. ”

Fang Yan's instinct when he first entered the tomb was completely wrong, this was not the ear chamber of the main tomb, it seemed to be more like an empty room on the outer layer of the underground that was specially used for anti-theft, this kind of empty room was often full of organs, so that some tomb robbers who had little ability but were lucky enough to dig in should go home as soon as possible.

The actual burial mounds may be deeper underground, and the safe entrances to the underground are generally extremely difficult to find.

"Don't touch that candle, zoom in." Professor Kim seemed to be paying special attention to the spontaneously combusting candle in the corner.

Er Zhu bowed slightly, and Fang Yan also squatted down to take a closer look, this is a very thick and short piece of yellow wax cake.

At a glance, you can see that its age is very old, and it is completely different from the slender candles widely used in later generations, the rough yellow wax skin is pitted, but the grease inside is very durable, looking at this posture, it will not burn out in three or five hours.

After witnessing it up close, Professor Kim was thrilled:

"No, Fang Yan, you are wrong, although the candles recognized by archaeology are from the Jin Dynasty, there was actually beeswax in the Western Han Dynasty, but it was not popularized. In the early years, I heard that there were occasional yellow wax cakes found in the Han tomb, but I didn't expect it to be true, and I saw it for the first time, which was a major discovery. The tomb in nearby Area B is also a Han tomb, but no yellow wax cake was found inside. ”

Speaking of this, Professor Jin was a little embarrassed: "I really want you to bring this candle back, but it is an evil thing that spontaneously combusts in the tomb, I don't think it should be blown out for the time being, but if it is not extinguished, it will be burned out soon." ”

Fang Yan didn't bother with this candle at all, his attention was all on the brick wall in front of him.

One of the biggest features of brick chamber tombs is that many brick paintings are carved with different elements such as religion, culture, customs, and farming.

He has been under similar brick tombs several times over the years, and the brick chambers of different periods and different cultural backgrounds have been contacted, and the brick surfaces are painted with different styles.

But most of the bricks here are carved with the same pattern - blood-colored four-leaf clover.

These four-leaf clovers seem to be arranged in a special formation, like a group of four-leaf clovers rooted on the wall, interspersed with a small number of portrait bricks, at first glance, it seems that they are all buildings, people, music and dance, chariots and horses, animal taming, mythological stories......

"It's strange, aren't the tombs of the Tuyuhun people 1,500 years ago? Why did the brick tombs of the Han Dynasty appear? ”

Although Erzhu is a layman, he still has some basic common sense.

"That's what puzzled me the most. There are several four-leaf clover mounds of different years, from 200 BC to 600 AD, and the more I think about it, the more confused I become. ”

Fang Yan opened the pouch on his back waist and took out a small and delicate flashlight. This flashlight is not small, it is made by the old American manufacturer Shenhuo Company, and it is a "gold special edition" tailored for the team of stealing the sky, which can be dimmed in multiple gears and is very power-saving.

As soon as the Shenhuo flashlight was turned on, it instantly drowned out the weak light of the Hydra searching on the wall, and Fang Yan searched for the few patterns on these red bricks from top to bottom, from left to right, one by one, except for the four-leaf clover.

At this moment, the candle standing in the corner of the wall was quietly extinguished......

"Hey, don't keep staring at these green bricks, what's so nice about bricks? The audience has opinions. Erzhu didn't close the ordinary barrage, and when he saw that the screen was full of complaints, he hurriedly reminded him.

"Green bricks?"

Fang Yan straightened up, looking confused, "Isn't it a red brick?" ”

That's right, it's obviously all red bricks here, and he hasn't seen a single blue brick, Fang Yan was sure from the first sight of these wall tiles that they were ordinary red bricks.

The difference between green bricks and red bricks is the temperature, if the temperature is high, it is red bricks that are burned, and when the temperature is low, it is green.

And the quality of red bricks is better, if you simply build walls or create a classical style, green bricks are enough. But if there is a more complex use, red bricks are generally used.

"You're kidding me, it's obviously a green brick."

Er Zhu rubbed his eyes vigorously, reached out and touched the cold brick surface, he was very close, but he didn't seem to notice the painting on the brick surface at all.

Or did he not see any patterns at all?

Regarding the dispute between the two, the barrage has given the answer as soon as possible:

[Green Brick] [I also look at Green Brick] [Green Brick +1]

[Visual inspection of Emperor Yan's red-green blindness] [Green brick +2] [My pants are all off, but you let me see the bricks? 】

[Hey, brother, watch your step, the candle is out.] 】

……

"Oops, when will the candle go out?" Erzhu hurriedly lowered his head and found that the previous candle that suddenly spontaneously combusted for some reason had been secretly extinguished again.

Fang Yan also sighed secretly, and scanned the bricks in front of him again, and found that they were indeed red bricks!

When there is a disagreement between two people on the scene, it is necessary to turn to a third person:

"Qin Shuang, what color do you see these bricks?"

Fang Yan turned around and asked, just waiting for Qin Shuang to light up her bracelet and give a word, "Qing"? Or "red".

However, she didn't give anything.

"Qin Shuang? Qin Shuang...... What about people? Fang Yan looked around and found that the cold girl who had been sticking behind him suddenly disappeared.

Looking back again, there are few people!

Erzhu also disappeared, and the huge Hydra VR camera also disappeared out of thin air!
