Xia Yulong whispered in Lan Xin's ear: "Xin'er, Xin'er, you wake up, you wake up." ”

Lan Xin slowly opened his sleeping eyes, looked at Zhang Xian, and then stared at Xia Yulong, and asked, "Brother, sister, where are we?" ”

Zhang Xian replied: "We fell into a deep pit, a very deep hole, you see that the hole is only the size of a bowl, I'm afraid we will be trapped in this hole." ”

"Ah......" Lan Xin looked surprised, looked in the direction that Zhang Xian pointed, and sure enough, the hole was only the size of a bowl, she turned her head, looked at Xia Yulong and asked, "Brother, how is this good?" Suddenly, she felt a tingling pain in the back of her head, and she screamed "Ah" and squeezed Xia Yulong's hand.

Xia Yulong looked at Lan Xin's painful appearance, a little overwhelmed, and he looked at Zhang Xian anxiously.

Zhang Xian checked the pulse of Lan Xin for a moment, and said: "Brother, you put your heart in your stomach, Xin'er is caused by impatience, the so-called impatience attacks the heart, and the heart dominates what you think, rest for a while and wait for the wound to heal, and then you will be fine, what matters now is that we have to think about how to get out." ”

Xia Yulong comforted Lan Xin a few words, he looked at the hole the size of the bowl above his head, and said: "Fortunately, we fell into this deep hole and escaped the pecking of birds and insects, otherwise we would have turned into white bones, and I don't know if the birds outside the cave have dispersed." ”

Lan Xin sat up and said, "Brother, why don't we let the water ghost seniors go out to find out the truth first, and then think about going out?" ”

Xia Yulong nodded: "This is the only way to do it now, tell the seniors of the water ghosts to be more careful." ”

Lan Xin sent instructions to the Dark Fireball through her heart, but she didn't see any sound, she shouted to the Dark Fireball in her heart, but still didn't see any response from the five ghosts, only to see her brows tightened, and the Dark Fireball overflowed from her palm and suspended it above the palm, she was about to cast a spell to force the five ghosts out......

Xia Yulong stopped: "Xin'er, don't, I saw in Tongtian's eyes that the five ghost predecessors had turned into five faint points of light in the Dark Fire Ball, and they hugged each other tightly, I am afraid that they will encounter something that embarrasses them again, they have their difficulties, let's stop embarrassing them, let's think of other ways." ”

Lan Xin nodded and said, "I listen to my brother." ”

Zhang Xian visually measured the distance between the entrance of the cave and them, and said, "This cave is really deep, the three of us have the best light work, and I will fly there at most......" She pointed to the top and a long way from the entrance of the cave.

Lan Xin withdrew the Dark Fireball into his palm, stared at the hole above his head, and sighed lightly: "Even if the five ghost predecessors can help me, my light skills can only be the same as that of Sister Immortal, alas, I don't know why they ......"

When it came to the five ghosts, Zhang Xian became angry, she snorted and said: "These lazy ghosts, but they made shrunken turtles at critical times, and they also said that they were strong, they were really not as good as half a finger of grandpa, if only grandpa was here." ”

Xia Yulong carried the fire fold, looked around, and said: "You also know my light skills, and it is half a foot high when you jump, hum, I'm afraid I can't go up to this hole, you see, this is a charcoal-burning kiln, it can't be only the mouth on the top of the cave, there must be other exits from these four walls, we have to find it." ”

The three of them walked towards the edge of the kiln with their arms in hand......

A thick layer of black charcoal ash was hidden on the kiln wall, and Zhang Xian took out his long sword and scraped a palm-sized place, revealing a golden color on the kiln wall.

Seeing this, Xia Yulong also scraped up the kiln wall with a shovel, his strength was naturally greater than Zhang Xian's, and the kiln wall was squealing, and after a few panting, the kiln wall had been scraped open by him, revealing a golden color in front of them.

Xia Yulong gently knocked on the kiln wall with a shovel, the kiln wall made a heavy muffled sound, and the aftermath echoed in the charcoal kiln for a long time and refused to disperse, he faintly felt uneasy, and said to himself: "Could it be that this kiln wall is made of metal?" ”

Zhang Xian asked, "Brother, what are you muttering?" ”

Xia Yulong looked straight and replied: "You see that the wall of this kiln is indestructible, and I don't know who did it, according to common sense, the kilns that burn charcoal are all made of fire bricks, and the walls of this kiln are much stronger than ordinary charcoal kilns, and I don't know who has such great ability." ”

Zhang Xian took the fire fold, looked at the scraped kiln wall for a while, and said: "Bronze casting flourished in the Spring and Autumn Period and the Warring States Period, I am afraid that this charcoal kiln was built at that time, and it is not the rich merchants who can have such a large amount of money, but the royal family, how much bronze is needed to cast." ”

Xia Yulong thought for a moment and said: "It is recorded in ancient books that although bronze is hard, its melting point can be low, even if it is gold, it may not be able to withstand such a high temperature. ”

Lan Xin stepped forward, touched the kiln wall with his hand, couldn't help but scream, immediately retracted his hand, and said, "This ...... The walls of the kiln are strangely cold, much colder than frozen water. ”

Xia Yulong and Zhang Xian stepped forward at the same time, tentatively touched the kiln wall with the back of their hands, and before they could blink, they retracted their hands one after another, and the three of them looked at each other with a shocked expression.

Suddenly, Lan Xin said: "Oh, I remember, when I was in the underworld, I heard the second elder of the underworld mention that the chain that binds the castle of the underworld is made of cold ice real gold, this cold ice real gold is extremely cold and abnormally strong, and it has been burned by the core lava for tens of thousands of years without melting, could it be that the material of this kiln wall is cold ice real gold?" ”

Xia Yulong rolled up his broken sleeves and said, "Xin'er, Xian'er, you get out of the way first, and wait for me to scrape all the charcoal ash on the kiln walls around here, and see if there is a way out of this kiln wall." ”

Zhang Xian took more than ten steps back with the help of the blue core, Xia Yulong rotated the shovel in his palm, and used the "sweep away" move, and in the blink of an eye, the phantoms of the spade wall overlapped, and black smoke billowed everywhere the shovel went.

Xia Yulong has been submerged in the smoke and dust, and bursts of choking smoke hit, and he shouted in the smoke and dust: "Xian'er, Xin'er, this black smoke is too choking, quickly cover your nose with urine." ”

Blue Core let out an "ah" and said, "This ...... It smells terrible, isn't it? ”

Zhang Xian chuckled and said, "Xian'er, don't rub it off, my brother is right, urine can detoxify." As he spoke, he tore two rags from his clothes, one of which he handed to Blue Core.

Lan Xin held the rags, his scalp was numb, and he said hesitantly: "Sister, I'...... I can't pee......"

Before the words fell, Zhang Xian had already covered Lan Xin's nose with a rag soaked with urine, and said, "If you can't pee, use mine, but hold it steady, don't get rid of it." ”

Lan Xin was so anxious that he screamed "mmmm", Zhang Xian laughed again, grabbed the dry rag in Lan Xin's hand, and covered himself after wetting the urine.

After a pillar of incense, Xia Yulong walked out of the black smoke and dust dejectedly, and said: "As long as the kiln wall is within my reach, I have shoveled it clean, and there is not even a single crack, let alone find a way out." ”

"Ah, really...... Is there no way out? I also said that the person who built this charcoal kiln would leave a way out for himself......" Zhang Xian said in shock, his previous confidence was gone.

Lan Xin raised his right hand and said angrily: "When I roast it with a yang fire, what the second elder of the dark lamp said may not be true, hmph, I don't believe I can't bake it." ”

Xia Yulong took a step to the right, pinched Lan Xin's right hand and put it down, and said: "Xin'er, don't bother, the hardness of the kiln wall is comparable to my shovel, and this kiln wall is extremely cold, I'm afraid that the yang fire will not be able to bake it, let's think of other ways." ”

At this time, the smoke and dust in the cave gradually dissipated, and by the dim yellow light of the fire fold, they saw that each other's faces were dyed black by the smoke and dust, only the tip of the nose and mouth were still white, and they looked very funny, but they couldn't laugh.

Below the kiln wall, a golden wall surrounded them, which was the kiln wall that Xia Yulong scraped clean.

Seeing that most of the fire had been burned, the three of them were anxious, like ants on a hot pot, and they couldn't think of any way.

At this time, Lan Xin had an idea, looked at the smoke and dust above the kiln wall that had not been scraped off, and said: "Brother, sister, look, after the dust under the kiln wall has been scraped off, it has moved to the dust above. ”

Xia Yulong looked at it carefully for a moment, nodded and said, "I know what Xin'er means......" As he spoke, he ran towards the edge of the kiln wall.

I only heard the sound of "dang dang dang", Xia Yulong picked up the shovel and knocked on the kiln wall violently, the smoke and dust on the kiln wall were scattered like a drizzle, and the whole cave was filled with smoke and dust that could not be seen in the five fingers.

After a while, the smoke and dust that fell became less and less, and Xia Yulong was too tired to do it.

Zhang Xian took away the wet cloth covering his nose and shouted, "Brother, it's okay, it's almost." ”

When the smoke and dust gradually cleared, they saw that there was a hole around the kiln wall, and a huge golden mural was displayed in front of them.

"Ah......h
