This afternoon.

Li Tianqi was idle, so he came to the alchemy room to check the refining of the pill.

"Senior Brother Li is here. The two alchemists in the alchemy room greeted each other warmly, these days, Li Tianqi often comes to the alchemy room, and he is very familiar with the two alchemists, Li Tianqi's cultivation is lower than the two alchemists, so the two alchemists will call Li Tianqi his junior brother.

"Two senior brothers, is the elixir almost finished?" asked Li Tianqi.

"It's coming soon, it will take a few more hours, and the elixir will be ready to be baked. A red-haired alchemist laughed.

Li Tianqi glanced at the alchemy furnace: "Huh, the flame temperature seems to be very high today." Li Tianqi was far away, and he could feel the scorching heat of the flames under the alchemy furnace.

"The temperature of the flames has been increasing these days, and I don't know what went wrong. The red-haired alchemist crooked his mouth.

Li Tianqi said with a smile: "The higher the temperature of the flame, the better the elixir refined, isn't it?"

"Not necessarily, the main thing is to look at the stability of the flame temperature, as long as the flame has been maintained at a temperature, then it is okay, if the temperature of the flame is high and low, unstable, then the phase of the refined pill will deteriorate, or even fail. Another white-haired alchemist said.

It's really weird to say, as soon as the white-haired alchemist finished speaking, the flames in the alchemy furnace began to shake, and the temperature became extremely unstable......

"This ...... What's the matter......" The white-haired alchemist was directly stunned.

The red-haired alchemist was also surprised: "It's so good, why did the earth fire start to become unstable......

"Oops!" The white-haired alchemist frowned: "The pill is probably going to go wrong......"

"Smack!"

There was a crisp sound in the tall alchemy furnace.

"It's over...... It's over......" Hearing the crisp sound, the white-haired alchemist's face changed greatly: "Pill...... Ruined ......"

The red-haired alchemist's face also turned ugly: "It's over...... The pill is ruined, and Steward Pang will definitely not spare us......"

Li Tianqi comforted: "This is an accident, not your responsibility, and Manager Pang will not blame you." ”

The white-haired alchemist smiled bitterly: "Li Daoyou, you don't know how precious this furnace of pills is, Steward Pang has thousands of instructions and ten thousand instructions that nothing can go wrong, but now, ...... If Steward Pang knew that the pill was destroyed, he wouldn't know how angry he would be......"

"Damn the Earthfire, you've really killed us!" the red-haired alchemist scolded hatefully.

"Huh......" The earth fire suddenly burst out from the eye of the wind around the alchemy furnace, and instantly wrapped the entire alchemy furnace, raging fire, and the burning alchemy furnace "crackled" for a while.

As the earth fire erupted, the temperature of the alchemy room also rose sharply.

"Senior brother, you hurry up to find Steward Pang, just say that the earth fire has suddenly become extremely unstable, let him hurry up and take a look. The white-haired alchemist said.

The red-haired alchemist nodded: "Okay, I'll go now." After saying that, the red-haired alchemist was about to leave, but at this time, a mutation occurred......

"Click!"

A crack suddenly appeared on the surface of the alchemy furnace, followed by a second and third ...... In the blink of an eye, the alchemy furnace was covered with dense cracks......

"What's going on...... red-haired alchemist and white-haired alchemist were stunned, this alchemy furnace was made of extremely cherished dark iron, it was very hard, and it had been burned by the earth fire for hundreds of years without a trace of damage, but how could there be so many cracks today?

Li Tianqi's face changed drastically: "It's not good, the alchemy furnace is about to explode, everyone flash ......" Before Li Tianqi finished speaking, the alchemy furnace exploded, and countless fragments of dark iron instantly covered the entire alchemy room, and at the same time, a large flame burst out from the ground, directly towards Li Tianqi and the others.

"Run!" shouted the red-haired alchemist, turning and running towards the door.

Li Tianqi and the white-haired alchemist were not slow to react, and they turned around and ran.

Seeing that the three of them were about to escape from the alchemy room, who knew that a huge suction force suddenly came from behind, and before the three of them could react, they were sucked back by the suction......

Li Tianqi was shocked and struggled desperately, but the suction power was too great, no matter how Li Tianqi struggled, he couldn't get rid of the pull of the suction...... Why are you so unlucky, you can encounter danger when you come to the alchemy room to wander around, this is too nonsense.

The red-haired alchemist and the white-haired alchemist were also frightened and struggled hard, but they were the same as Li Tianqi's fate, no matter how they struggled, they couldn't get rid of the pull of suction.

"Click!"

A huge crack suddenly cracked in the ground, and a scorching aura emanated from the crack.

Before Li Tianqi and the others could react, they were pulled directly into the crack by the suction......

Li Tianqi's face changed greatly, and he hurriedly sacrificed a defensive light shield to disperse the heat wave that was blowing in his face.

The two alchemists have been dealing with fire all year round, and of course they also have a set of methods to resist the flames, but they saw that the two of them pinched a magic decision with both hands, and a white light covered the two of them, and the heat waves that came from the ground were all blocked by the white light.

"I said two senior brothers, what the hell is going on!" Li Tianqi shouted loudly, since he was pulled into the crack, the suction force that bound him suddenly increased greatly, making Li Tianqi even more hopeless to escape.

"We also wondered, we've been here for decades and we've never been in this situation. The two alchemists said depressedly.

"It's really unlucky, why did I come to the alchemy room with such a good look, how good it is to stay in my own room......" Li Tianqi didn't mention how much regret he had at this time.

"Whirring ......"

A fire suddenly burst out from the ground, engulfing Li Tianqi and the two alchemists in an instant.

The fire came and went quickly, and in the blink of an eye, the fire automatically retracted, and it was strange to say that after the fire retracted, the suction that bound Li Tianqi and the others disappeared.

After the fire subsided, Li Tianqi and the two alchemists were stunned for a moment, and the three of them were standing on top of an uneven stone at this time, surrounded by a sea of fire, and as far as the eye could see, this was a huge and incomparably large karst cave, so big that it was shocking.

"It's ...... Underground Cave ......" The red-haired alchemist looked around in disbelief: "What a big underground cave......"

The white-haired alchemist was also shocked: "Good guy, this is simply a sea of fire." ”

"Huh?" Li Tianqi suddenly wondered.

"What did Li Daoyou find?" the two alchemists turned their heads to look at Li Tianqi at the same time.

Li Tianqi stretched out his hand and pointed to the stone under his feet: "Do you feel a chill coming from this stone?"

"Cold?" The two alchemists were stunned for a moment, and then a hint of surprise appeared on their faces: "This stone is really exuding cold energy......

"Look. Li Tianqi stretched out his hand and pointed at the flames around him: "Did you find it?" The flames around him didn't dare to approach this stone at all. ”

The two alchemists hurriedly raised their heads and looked around, and sure enough, just as Li Tianqi said, the flames around them kept tumbling and jumping, and they didn't dare to approach the stone they were standing on.

"I see!" the red-haired alchemist suddenly shouted.

"What do you know?" asked Li Tianqi suspiciously.

The white-haired alchemist was also surprised.

The red-haired alchemist had an excited look on his face: "I know the origin of this stone......"

"What is the origin?" asked Li Tianqi and the white-haired alchemist in unison.

The red-haired alchemist exhaled lightly: "If I'm not mistaken, this stone under our feet is the legendary cold stone. ”

"What? is this the Cold Stone?" the white-haired alchemist exclaimed, it was obvious that the white-haired alchemist knew about the Cold Stone.

Li Tianqi blinked: "What is a cold stone?"

"The cold stone is a kind of heaven and earth strange thing, which can only be formed in the land of the sun...... I've only seen it in classical books, but I've never seen it in kind...... I really didn't expect that there was still a cold stone hidden under the Refining Sect, and judging by the color, it should have existed for a long time. The white-haired alchemist exclaimed.

"This is an underground cave, the flames are surging, it stands to reason that the temperature here should be very high, it is difficult to resist with our cultivation, but we can feel a trace of heat now? Speaking of which, the lives of the three of us are saved by this cold stone, and it is precisely because of this cold stone that the flames around us dare not approach us, and the heat of the flames is also dispelled by the cold stone, in the end, our lives are really big, if we don't encounter this cold stone today, it is estimated that the three of us would have been burned to ashes. The red-haired alchemist said.

"Is this cold stone very precious?" Li Tianqi asked, "Except for the fact that it can emit some cold air, I can't see anything special." ”

After listening to Li Tianqi's words, the red-haired alchemist smiled directly: "How precious, it's simply a peerless treasure, Li Daoyou, do you know how the cold stone is recorded in the classical books?"

"How is it recorded?" asked Li Tianqi curiously.

The red-haired alchemist stretched out six fingers: "The coldest thing in the world." ”

Li Tianqi's expression was stunned: "The coldest thing?" Li Tianqi looked down at the stone under his feet: "Isn't it an exaggeration in the classical books, the cold air emitted by this cold stone is very ordinary......"

"General?" the red-haired alchemist pouted: "The cold qi emitted by the cold stone now is simply fur, if it releases all the cold qi it contains, it is estimated that we will be able to turn into popsicles in an instant." ”

"Popsicle?" Li Tianqi twitched cheekily: "Is it so powerful." ”

"Believe it or not, that's what the classics say anyway. After speaking, the red-haired alchemist added: "The ancient books I read are treasured by the Refining Sect, and there is absolutely no need to doubt the real surname." ”
