Inside the door is a grotto that is several feet high and as wide as a hall.

Red light and heat waves came from the center, and there was a constant gushing spring, but instead of water, hot red lava gushed out of the spring. The magma formed a pool of magma around the spring, and the walls of the pool were made of dark green stone like the stone gate, and the magma at such a high temperature could not be damaged in the slightest.

Behind the pool, there is a huge stone statue as high as several feet, the outline of the age is a little blurred, you can vaguely see that it is a person in armor, both hands press a long knife engraved with a dragon-shaped pattern, the two huge horns on the helmet are particularly conspicuous, the strange thing is that his face is actually the same as the statue on the stone door is a blue-faced fanged grimace, the hideous face is still clearly distinguishable under the erosion of time.

I don't know why, Ye Feng felt that this dragon-shaped pattern was very familiar at first glance, but he didn't remember when he had seen it at all.

Everyone was stunned, and Zhang Idiot muttered: "This, this is really ......" The footsteps moved, and suddenly exclaimed.

When everyone looked at it, it turned out that he had stepped on a corpse, and he had been dead for I don't know how many years, and in this hot and dry environment, he was roasted into a dry corpse. As far as the eyes can see, there are such dried corpses all over the grotto, and there are twenty or thirty corpses at first glance.

Tang Da looked at a dried corpse next to him, and couldn't help but sigh, he saw a leather bag hanging from the corpse's waist, and the pattern workmanship was clearly a thing of the Tang Sect. Reaching out and digging it out, it really contained several hidden weapons of the Tang Sect. Looking at the corpse next to him, he died under the secret weapon of the Tang Sect, and there was a waist card of Thunderbolt Hall on his waist. Everyone inspected the corpses one after another, and found that they were all from the Tang Sect and the Perak Hall, and they were confused for a while.

Zhang Idiot walked to the edge of the pool, and the scorching sensation was even stronger, and he felt as if the hair on his body was about to burn. Next to the pool, there are more than a dozen strangely shaped stone platforms and stoves that are also made of dark green stone, and Zhang Idiot can't help but exclaim after a little inspection: "This, this is an iron furnace!"

Everyone looked at each other, not knowing why. Zhang Idiot carefully groped for the traces of the pattern on the stone platform with his hand, and exclaimed again: "My good man, this thing is at least something from before the Shang and Zhou dynasties." ”

One sentence made everyone can't help but be shocked, a cave before the Shang and Zhou dynasties, lying full of corpses of disciples of the Tang Sect and the Thunderbolt Hall, the Great Thunder Gate has been established for nearly 20 years, which shows that these corpses with the waist card of the Thunderbolt Hall are also from at least 20 years ago, how can there be such a place in the depths of Huashan? Where did the dried corpses all over the place come from? For a while, everyone looked at Fan Shanggu, the head of Huashan.

Fan Shanggu looked at everyone looking at him suspiciously, and smiled slightly: "When I first came in twenty years ago, I had the same reaction as you. He patted his disciple Yao Daochang on the shoulder, motioned for him to put himself down, and said, "Originally, the secret here was to be passed on by word of mouth to the successor head who sent me in when I was about to return to heaven. Now that the situation is critical, the Huashan faction has also reached the autumn of life and death, so I can't take care of it, so I won't hide it from you. What I know is what my master told me before I came in with my master. ”

As soon as everyone heard this, they immediately gathered around Old Man Fan, resting their feet and listening carefully.

"This starts with He Zhenren building He Lao's stone chamber and digging a secret passage. After taking a sip of water, Fan Shanggu's breath gradually calmed down a lot, "Back then, He Zhenren gathered a group of anti-Yuan righteous people who were good at earthwork to dig this secret passage, originally to collect all kinds of anti-Yuan righteous people and related materials, and prepare for future troubles and conspire to recover our Han people." It is said that after digging for almost half a year, he suddenly found that he had dug through the road outside the door, and when he entered here, He Zhenren was also surprised. ”

He turned to Zhang Idiot and said, "You can see that this is the relics of the Shang and Zhou dynasties, and it is not simple, but He Zhenren found a sheepskin scroll in the grotto, and no one can recognize the ancient characters on it. After checking the history books and searching for well-educated people, I found that the age here is much earlier than the Shang and Zhou dynasties. ”

Zhang was stunned for a moment: "Could it be that Shang Zhou had metallurgy before that?

Fan Shanggu smiled slightly: "Have you heard of the Battle of Zhuolu?"

Zhang Idiot and the others all changed their faces greatly: "It was the legendary decisive battle between the ancient demon god Chiyou and the Yellow Emperor of China, and it was thousands of years ago. ”

Fan Shanggu nodded: "In the "Classic of Mountains and Seas", it is recorded that Chiyou has a bull-headed human body, and the army is all copper-headed and iron-clad, invulnerable, do you think it is a myth and legend?"

Zhang Idiot looked back at the horn helmet of the statue, and was dumbfounded: "Could it be that at that time, Chiyou actually had metallurgy and metal armor?"

Fan Shanggu pointed to the huge stone statue and said: "Yi Zhou Shu" cloud: Chi You is a smelter, using gold as a soldier, that's what it means. According to the records on the sheepskin scroll, this is supposed to be a forge built by Chiyou for forging armor blades. ”

Everyone was in an uproar, it's incredible, this is actually an arsenal built by the legendary ancient demon god more than 4,000 years ago?
