The gate was silent, and the speed was even and slowly opened, and then a gust of wind blew behind the cloud cliff and went directly into the tower gate. The wind came too suddenly, and the three women not far from this door all felt the breeze caressing their bodies, and they couldn't help but look in the direction of the tower gate.

The fact that the door opened so easily made Yun Ya Nuan stunned for a moment, but what happened next made his jaw almost drop to the ground.

The breeze poured into the tower, and the originally dark space began to light up. The walls are lined up in rows, starting from the door, and candlelight is lit inward.

Several people stood in place in amazement, like puppets, and for a moment they seemed to be stupid.

Kexin was the first to wake up, walked into the tower a few steps, looked at the fire at the bottom, and stared.

Yun Ya Nuan saw Ke Xin walk in, and hurriedly pulled her arm, he was worried about the air quality inside, after all, it seems that there has been no air here, otherwise these flames will not be bright when the wind enters.

But the hand was a step slower, but Xin had already walked into the door and began to study the candle-like firelight, Yun Yanuan thought that since the fire was burning, it was estimated that there was nothing wrong with people.

But he still took a step forward, grabbed Kexin's arm, and said, "I'll go in later, ventilate first, I'm afraid it's not that it's been trapped inside for too long, and there will be unpredictable bacterial gas." ”

Kexin realized how dangerous his behavior was, and jumped out as if he was running away, exhaling vigorously outside, wanting to spit out the air he was gasping for just now, and he looked very smiling.

Diana looked at the fires and was a little frightened, and couldn't help asking, "How could those candles light themselves?" Could it be a ghost? As he spoke, he leaned closer to Yun Yanuan.

Ke Xin shook his head with a smile and said, "It's not a ghost, it's the breeze outside that ignites the fire." ”

Yunya Nuan and Diana were very puzzled, there is wind and air, which is just one of the conditions for combustion, but after all, the wind does not have the ability to ignite directly, because combustion requires ignition point, and ignition point requires high temperature.

Maya didn't care about any of this, and looked at the bright hall illuminated by candles, a little distracted.

Ke Xin pointed to a candle flame at the door and said, "This candle flame is similar to the everlasting lamp in the tomb, the wick has been specially treated, and it contains a substance with a very low ignition point like white phosphorus.

The lake is very warm, and the mountain is a volcano with abundant geothermal heat, which is why this environment with snow and vegetation is formed. The wind on the surface of the lake is relatively warm, probably just above the ignition point of the wick.

This kind of wick technology can be made long ago in modern times, but it is indeed difficult to ensure that it will not deteriorate for 10,000 years like here. ”

Yun Yanuan nodded, he had heard of the kind of tomb ** everlasting lamp, although he didn't know the principle, but he didn't feel that there were any gods and ghosts, but Diana didn't know this, and she was still confused.

For this reason, Yun Yanuan had to explain to Diana in English, and in a scientific way, the woman nodded, indicating that she understood, and then drew inferences:

"These lamps can still continue to burn after thousands of years, it must be the credit of this tower gate, the strict gate isolates the air inside and outside the stone tower, so these fires burn out automatically after running out of oxygen, so that the fuel is preserved, right?"

Kexin and Yun Yanuan nodded together, indicating that this was what they meant.

However, Ke Xin still added: "However, all this must be based on the fact that these lamp oils can burn for a long time, you see, the candle flame has been lit for a while, but you can see that this is like a solidified lamp oil, there is a slight change?" ”

A few people looked at it, and sure enough, those solidified and crystalline white oils were holding a flame, but the lines below did not change at all, and there was no sign of melting at all.

"I'll go, what kind of fuel is this? It's too good, it's not lost at all! Yun Yanuan exclaimed.

Kexin smiled: "It's not a loss, it's just that the reduction is too slow, and I can't see it at all, so I guess it's mermaid oil, that is, the oil on the mermaid." ”

The ancient books of the Classic of Mountains and Seas, the Naturalist Chronicles, all have records about the mermaids, but they can cry tears into beads, weave silk yarn, and are very clever and ingenious creatures. The grease in its body can be bright for more than 10,000 years.

The lantern in the tomb of Qin Shi Huang in ancient times is said to be made of shark oil, but it is difficult to know whether it is true or false.

Outside, the sky was getting darker, and the white fog was hidden in the darkness, but the bitter cold of the night did not appear, and it was thought that it was because of the hot spring lake.

Yun Yanuan estimated that the time was almost up, thinking that the air inside the tower had already blended with the outside, and they had no place to look for firewood to burn here, so they couldn't help but pay attention to those Jiao Oil Lanterns.

I begged to get down a hundred and eighty of these lanterns, that is, a bonfire, boil a broth and boiling water, there must be no problem, so I strode into the tower, and slowly entered along the right wall.

Be careful so that the 10,000-year-old ship can't be ugly when you slip away.

The structure of this hall can be described as ingenious, not an empty view, but semi-closed, a screen-like partition, which does not appear crowded, but does not make people feel empty, and is natural.

The ever-bright lamps on the wall are about a meter apart from each other, and between every four candles, there is a colorful mural, birds and animals, birds and flowers, everything.

Ke Xin pointed to a picture and smiled: "Look, that person seems to be cooking!" ”

A few people looked in the direction of her finger, and saw a man in a light robe, with three long wisps of beard, the top of his head blooming, holding something that looked like a lingzhi on his left and right, and a round three-legged tripod in front of him.

The mural is lifelike, with bursts of green smoke rising from the three-legged tripod, the flames under it steaming, and the man's other hand unraveling the tripod, as if to throw something into it.

Yun Yanuan estimated that this was either cooking or boiling medicine, but looking at the comfortable enjoyment on this person's face, it was estimated that it was more likely to cook, and he couldn't help but want to laugh, such an ancient stone tower, the murals inside, there would be a picture of cooking.

According to his understanding, the murals in the general tower are mostly descriptions of fairyland, and such murals with the breath of life are still ancient murals, which are indeed rare.

However, this is not the most exaggerated, Ke Xin pointed to another painting and said: "Look, that person should be making tea, tsk, really enjoy it!" ”

Yunya Nuan was also a little confused by these murals, and hurriedly looked at them one by one, this is good, planting vegetables, breeding, weaving, painting, winemaking, everything, at first glance, it is simply the Tiangong version of the Qingming River.

However, they soon tasted a completely different taste, and that was the temperament of the characters in each painting. It seems that they are not working, but enjoying, although they are doing red dust things, but they make you feel that everything is transcendent outside things, fairy and otherworldly.

Although a few people haven't finished reading half of these murals, this feeling from the inside out has made them feel a little ashamed of themselves for some reason.

"Why? Why do all these things we do every day look so wonderful on this mural? Diana sighed as she shook her head.

But his face was bright, his face was dignified but not serious, like a devout believer, and his voice said softly: "What is shown on this mural is the ...... of the Three Thousand Great Roads."
