Director Hu's words reminded me of the bronze chains I saw when I entered the mysterious crevice under the Yellow River, and the chains were torn from the underground peaks,...... There are also those hundred-meter-high ancient trees in the depths of the cracks in the ground, and there are also bronze chains that go straight down, which is extremely shocking, and these chains are at least a few hundred meters each, and each one is the thickness of a child's wrist.

Why is there the same chain in the lock dragon well under Jinan City?

Could it be that the underground of Jinan is also the place where those prehistoric people lived?

At that time, after coming out of the cracks under the Yellow River, I also specially learned from relevant experts, and everyone said that the known bronze could not be preserved for so long, because bronze is soft among all metals, and it is also the most easy to rust, not to mention thousands of years, even in the damp underground, it is almost impossible to preserve for hundreds of years.

In addition, I also cut down the metal chains with a knife to the metal fragments, and asked Liu Xi to use the most advanced instruments to test them, and according to the test results, it was confirmed that these metals were not traditional bronze, or even metals in the sense of the first glance, but a very special alloy - completely different from the alloys known on earth.

The more I thought about it, the more curious I felt, so I discussed with Wu Jinghan whether to rush over and take a look.

This is exactly what Wu Jinghan meant, after all, he is a graduate student in archaeology.

The two of them took a taxi to the mineral water factory located in the northern suburbs of the Yellow River, and outside the workshop they had entered before, they first saw a large pile of soil, the size of a small house, and there were workers in it who continued to push the cart out with small carts.

The two of them went straight to the workshop.

Everything in the workshop had changed, the big buckets and the mess were gone, replaced by dozens of people and improvised digging machines.

Director Hu was not there, but several old men and Haoyu were there, and the previous well had become a big pit at this time, and five or six strong men were standing by the well, pulling metal chains up from the well.

At first glance, it looks like a tug-of-war.

"Come here! The Ludon brothers. ”

Seeing me, Haoyu greeted me from afar.

The old glasses and the others also turned their heads to look at me.

"Guys, what's the matter, there's a long metal chain in the lock dragon well?"

The old glasses nodded: "We didn't know before, because the stone tablet back then was not completely deciphered, and now it seems that the dozen or so unreadable words should be about this bronze chain." ”

"But...... But 4,000 years ago, how could such a thick chain be made? ”

In fact, I have long been admired by the wisdom of the ancients, and I believe that one of them can make such a metal chain - for example, the Dongyi tribe where Chiyou was located back then.

The smelting technology of the Dongyi people is supposed to have been obtained from the mysterious prehistoric civilization under the Yellow River, when humans did not invent paper, and there was no writing to facilitate the recording of information, so these processes are destined to become a historical mystery.

Retracting my thoughts, I quickly asked again: "So why did the ancients make such a long chain with so much effort?" ”

Professor Han took over the conversation: "It should be related to the lock dragon well, this should be the chain that locks the dragon - we thought it was just a legend before, but we didn't think ...... it."

Before he could finish his sentence, suddenly the whole earth vibrated violently, and it was accompanied by a low roar, like the barking of an old cow, but the sound was even higher!

Immediately afterward, several strong men who were pulling up the bronze chain screamed almost simultaneously and fell heavily backwards.

A few of us looked at the past at the same time, and we saw the metal chain being pulled back down the well at great speed.

The roar came from the depths of the puddle, and it sounded like it was coming from the depths of hell.

"It's a dragon? The suppressed dragon in the lock dragon well? Is he awake? ”

The old glasses roared, did not advance but retreated, and rushed directly to the puddle.
