The kiln fire was extinguished, and the temperature in the thousand-year-old kiln city was getting lower and lower.

At first, no one cared: the flames burning in the tens of thousands of ancient kilns were the only reason for the scorching heat and dryness here. After so many flames are extinguished, it is natural for the microclimate in the space to cool down.

As time passed, the temperature in the boundless darkness gradually changed from more than thirty degrees to more than twenty degrees Celsius and then to single digits—even at this time, several Grandmaster masters in the confrontation were still not alert.

Ying Xingtian frowned slightly, subconsciously feeling that this cooling speed was too fast, but he didn't delve into it.

The underwater underground cave has a temperature difference of ten or twenty degrees from the outside world, and it is a little chilly for cultivators, and it can't affect themselves at all. If it weren't for the rapid cooling at this moment, they might not even notice it.

However...... After the single-digit drop, the magnitude and speed of the cooling did not change much.

In the boundless darkness, the temperature is still stable and continues to fall.

Zero.

-1 degree, -2 degrees, -3 degrees Celsius......

The temperature reached zero degrees Celsius, and the rate of continuous decline was not as fast as before.

It takes about five minutes or so before it drops by one more degree.

It was not Ying Xingtian and Worm Dao who calculated this speed, but the last person who appeared in the Silkworm Mei Dao.

This high-level member of the "Yandao" organization made up his mind from the very beginning to pay attention to the benefits of being a "yellow bird", but he didn't expect to be directly exposed to the first two because of the collapse of an ancient kiln.

At this moment, he was hiding in the dark, casting a breathing spell to protect himself and the three disciples behind him, but there was always a battle between heaven and man in his mind: Win Xingtian didn't seem to have too much effort to defeat Qingqiu, and the giant python that the three Gu Dao Sect Masters had worked hard to hold back for a long time didn't know where to catch the kid surnamed Ji to eat alone.

In such a situation, do you still have to wade into troubled waters?

But think about the boundless ancient kilns, formations, and gems at this moment, and the "Mountain Dragon Array" at the entrance that plays a major role in him...... Ou Haichao's heart hurt and almost dripped.

Reluctant, really reluctant!

Is it a once-in-a-lifetime opportunity to go back with only a bag of gems worth less than 200,000 yuan?

Under such a tangled and hesitant mentality, he had the heart to constantly observe the surrounding situation, and almost idlely and boredly calculated the speed of the temperature drop in the cave at this moment.

It's starting to get a little cold.

There's something weird in this space underneath!

Somewhere ahead, there was a sudden sound of small pebbles rolling.

Ou Haichao's heart sank slightly, and he hurriedly took the three disciples and quietly took a few steps back into the distance.

Then the expected furious fist came as scheduled, and Ying Xingtian didn't hesitate at all and took an arrow step, and punched out fiercely towards the place where the sound came.

The scorching qi and blood brought by the martial arts master swept away the chill in the surrounding area.

"Bang!"

Listening to the sound of the argument is only the most basic ability for a martial artist, and he is almost 100% sure of winning Xingtian in the moment of punching, and sure enough, he hit the person who made the sound without any fancy - all his subordinates were slaughtered by the criminal soldiers and the insect and the Dao, and Ji Yiming was captured by the huge Gu snake again, and only the enemy was left here.

His heart was full of boundless killing intent, but he was slightly distracted when his fist hit the opponent.

This touches ......

It's not like hitting a human flesh and blood, it's like hitting a hard piece of ceramic.

Then, with the "bang" of the punch, there was a crisp cracking sound on the target's body.

In the sound of "clanging", it seems that countless ceramic and glass shards have fallen from the air and scattered all over the ground.

What is it?!

He was wondering in his heart, but there was a sudden sound of Gu worms flapping their wings and a foul smell next to him, and it was the Worm Dao Sect Master who also attacked at the same time when he heard the sound of battle.

An understatement of a finger and a punch popped out, and the scorching heat in the sky instantly shot down all the unknown Gu worms that rushed over, and Ying Xingtian immediately reined in his qi and blood and internal qi, and the footwork of "Xingtian Decision" was displayed, and the position was changed again and disappeared into darkness.

The person who shot the worm did not dare to pursue, and also fell into silence.

Before leaving that position, Ying Xingtian directly "sucked" a fallen object from the ground and quietly pinched it in the palm of his hand.

Sure enough, it's not human flesh and bones.

The tentacles were cold, smooth and hard, with sharp burrs around the edges, like shattered ceramicware.

But...... Although Fang Cai's thing doesn't feel like a human touch, it still has a simple defensive action before the middle punch, and its size is ...... It also seems to be very similar to normal humans.

If it is ceramics, with the scale of those ancient kilns that we have just seen, it is impossible to fire such a huge thing.

His fingers pressed slightly, but the smooth and hard "porcelain" fragments did not move at all, and it was not until he used three points of internal breath to transport the "Heavenly Decision" that it was crushed into foam by an irresistible force.

It is indeed ceramics! And it should be the ceramics that have been fired by the blazing kiln fire for thousands of years in this ancient kiln city.

Ordinary objects can't resist their power even if they don't carry their internal breath.

Since the kiln fire went out, this area has really become more and more weird.

These thoughts flashed through Ying Xingtian's heart, but all his attention was still focused on the darkness around him, sensing even the slightest trace of aura emanating from the Worm Dao, Qingqiu, and Naou Sea Tide.

Compared to the hatred of the "Qianlong Yuan" comrades being killed, anything can be put aside first.

And he didn't think that the "weirdness" in this kiln city could threaten him.

(It's getting colder, though.) ）

(This temperature should be minus five or six degrees, right?)

……

……

Zhou Ze, whose expression and movements were extremely strange, turned around and ran wildly into the darkness, Ji Yiming waited in place for a long time before starting to inspect the small pagoda-shaped caves again.

The terrifying Gu Snake with a red golden head and a blue-purple body still followed him closely, expressing affection for no reason with its head and letter from time to time.

It's just that Ji Yiming is studying the reasons unintentionally at the moment.

While checking with the small light on his goggles and recording the line of numbers under the "Xiankang Trial Jianyuan Remake" in each kiln, he sensed the sharp drop in temperature in the air around him.

A few degrees, more than a dozen degrees, I don't feel anything for Ji Yiming. Even if he only wore a thin shirt on his body, the warm and swollen "Taiyi Longevity Formula" in the meridians could still make his activities not affect anything.

But over time. When the temperature around him gradually dropped below zero, and even his breath would bring out a thick white air, this inexplicable chill made him feel a little uncomfortable.

This is still because of the practice of internal breath to become a martial artist, if you change to an ordinary person, I am afraid that it will not take a few minutes, and your hands and feet will be cold and your blood will be stiff, and you will be unable to speak.

Ji Yiming spat out a white mist, and turned his head to look at the Gu snake around him who seemed to be unaware of the temperature change: "For cold-blooded animals, shouldn't sub-zero mean that their mobility is weakened and they are ready to fall into hibernation?"

The Gu snake wagged its tail like a dog, tilted its head to look into the darkness next to it, and seemed to be more active than when the temperature was normal. And in the darkness in the distance, where it was not illuminated by the dim yellow light, there seemed to be a shadow flashing by.

One person and one snake have inspected six or seven pagoda-shaped ancient kilns in a row, and the numbers left in each one are different and there is no pattern at all. Although Ji Yiming didn't know what they were for, he always felt that they were also extremely important clues, so he simply recorded all these numbers in the mobile phone memo.

Three Bai Lingqi, Wu Bai Shi One, Two Bai Yi Yi Yi ......

Three hundred and one pick-up, two hundred seven pick-ups, and two hundred pick-ups......

He first recorded it according to the font on the brick kiln and used ancient traditional notation. After memorizing a few in a row, I couldn't see any pattern for the time being, so I was just lazy and converted it directly into Arabic numerals.

307、541、211……

314、277、49……

When the seventh ancient kiln was found, there was still no gain, and he was only ready to record the next number. He rubbed Ji Yiming, who was slightly stiff with his fingers, and his eyes suddenly stayed on the second row of the mobile phone memo.

No, wait a minute!

Why is this string of numbers so familiar?

He quickly removed the bag from his back, unzipped it and took out two books inside.

"Cixi County Chronicles", "Yue Kiln Porcelain Appreciation".

Turning the copyright page after the title page of the first book, the number on the library's blue stamp is "211458". On the second copyright page, the Dewey decimal code behind the column "Book in Edition Cataloguing Data" is "314277".

The third ancient kiln that was just investigated, the number is 211.

The fourth and fifth combined, which happen to correspond to the 314 and 277 of "Yue Kiln Porcelain Appreciation"!

Coincidental?

This thought only then arose, and it was quickly dispelled by Ji Yiming - Jiang Zhiyou left a lot of seemingly unrelated clues in the whole incident, basically each of which was extremely related to this ancient kiln and its secrets. And the probability that all nine consecutive digits will be exactly the same is so low that it is almost impossible to exist.

However, what does the library code of Hanzhong University mean that it is exactly the same as the number of the ancient kiln city in the Eastern Jin Dynasty more than 1,000 years ago?

Ji Yiming's heart moved slightly, remembering that when he found these two books in the library search system before, the codes in the system had been changed once. Before, he only thought that Jiang Zhiyou was hiding the clues deeper in order to confuse the food and audio, but now that he thinks about it, he deliberately made these numbers into codes.

It is estimated that even these two books may not be in the school library, but the things that Jiang Zhiyou brought into them.

(So these two strings of numbers correspond to a total of four ancient kilns!)

Blocks 314, 277, and 211 have all been found, and there is still one marked 458 missing. And these four ancient kilns marked by Jiang Zhiyou's clues must be different from other ancient kilns.

He took a deep breath, moved his body to dispel the growing chill around him, and turned directly towards the nearest "211" ancient kiln behind him: he didn't find any clues, maybe it was because of the lack of pertinence and contrast.

This time, it may be a little different.

As he turned, the giant Gu snake glanced curiously at somewhere in the darkness again.
