The canal is very wide, completely cutting off the entire mine, and there is no road in front of it, so everyone looks at each other: "How do you look like an ordinary mine cave here, and there is really a copper sword?" ”

Elder Jiang stopped at the water's edge for a while, and when he saw that there was no bridge nearby to cross, he actually raised his breath and jumped to the water. His lightness technique was no less impressive, and with a tap on his toes, he swept to the opposite shore in a few breaths.

Now that Elder Jiang has reached the other bank one step ahead, the other disciples can only stare dryly, these people are far from having martial arts attainments like Elder Jiang, and crossing the river is a problem.

And Tufuzi was completely dumbfounded, when it came to kung fu, the three of them couldn't get on the stage, or why don't they just swim over?

A few people said they would do it, but out of nowhere, a girl snatched the torch from him, and said with a smile: "Brother, borrow a fire." ”

Tufuzi turned his head, the man was dressed in a yellow and white waist-length skirt, with a slender waist like a willow, and a white jade flawless face bullying frost and snow, which was thrillingly beautiful and charming.

She held the torch and looked at the water, the fire was scorching like a dyed glow, and her eyebrows revealed a heroic spirit, which was even more unforgettable.

Dong Qingxian stepped forward, he looked at the other side of the river, and Elder Jiang, who had crossed the river before, had long since disappeared.

Dong Qingxian hesitated for a moment, and the warm voice of the spring breeze sounded in his ears: "I'll take Yan'er over." ”

As soon as he finished speaking, he was ashamed first, his eyelashes fluttered, and he didn't dare to look at him with a pair of clear spring eyes, and he didn't know if Yan'er would agree.

"There's no hurry." Liu Ruyan's mind was rough, and she didn't notice these small movements at all, "Don't rush to the road until you find out the whereabouts of Xuankun Yin."

Liu Ruyan retracted her gaze, and she walked to the other side of the river, where there was a behemoth several feet high, if you didn't look closely, it looked like a protruding rock. With the help of fire light and night vision, she found that this was actually a Kong Ming car.

Kongming cars were powered by water flow and were not widely used until the previous dynasty.

Now seeing one here, Liu Ruyan was a little surprised, it turned out that there were tools similar to Kong Ming cars as early as a thousand years ago, and the whole waterwheel was made of iron birch, which was extremely solid.

She held the wooden pole at the bottom and tried to turn it upward, and with the movement of her hand, the sink started the flow of water, and with the force of the flowing water, the whole waterwheel was fully operational.

When the waterwheel turned to the second week, there was a loud bang at the bottom of the water, and two iron chains broke through the water, spanning the entire surface of the water.

"What is this?" Tufuzi who came with him was obviously surprised, and he didn't expect that there was a secret hidden under the water, and he could make such two iron chains.

Liu Ruyan was also surprised for a moment when the chain came out of the water, and then understood how the copper ore was transported across the river back then.

Turning the wooden pole, she explained: "The waterwheel drives the chain, and if there is a bamboo basket hanging from the chain, the ore in the basket can be transported to the other side. ”

As the waterwheel turned, the ore from the other side of the river was transported, and someone at this end immediately unloaded the ore and transported the empty basket over.

Wonderful, really wonderful.

A thousand years ago, there were such craftsmen who created such a huge water project.

On the riverbank, Shen Yanchu looked at Liu Ruyan at the water's edge from afar, and a faint smile appeared in his eyes, like the morning glow reflecting the snow, and the ice and snow were melting.

This scene happened to be bumped into by Ling Feng, and he almost thought he was dazzled.

Ling Feng blinked his eyes vigorously, and when he looked at the Lord again, Shen Yanchu still had that cold look.

Well, it's really blind.

The crowd approached the watermill one after another.

Ah Lan walked out of the crowd, he checked the waterwheel with great interest, and then raised his lips and smiled: "The girl took a lot of trouble to fiddle with the waterwheel, could it be because she hasn't seen it?" ”

Without waiting for Liu Ruyan to respond, Fu Xin couldn't help but sneer: "A woman is a woman, and so many moths come out, it's like I've never seen a waterwheel." ”

Liu Ruyan is not the kind of person who gets angry easily, but when he saw a second lord like Fu Xin, he was polite when he spoke again.

"I said, you and Dugu Shaoxia are brothers in the same sect, why do you look different from ordinary people?"

"What's the difference?" Fu Xin shouted, "What do you mean, don't mess with me!" ”

Liu Ruyan raised her forehead in thought, "I see that you have fewer roots than normal people...... Tsk, this shouldn't be......"

Ah Lan saw Liu Ruyan knock her head with her fingers, and suddenly came to her senses, and immediately held back her laughter.

Fu Xin was annoyed and angry, "What are you laughing at!" ”

Liu Ruyan put down her hand and asked Xiang Alan, "Now do you know how to cross the river?" ”

Ah Lan nodded, "Thank you girl for helping." ”

Fu Xin rolled his eyes, his face full of disdain, "Why do you want to thank her." ”

Dugu Yi shouted, "Senior brother, don't be rude to the girl!" ”

Fu Xin still didn't see the slightest bit of fame.

Until Ah Lan and Elder Ren jumped onto the iron chain, and with the support of the chain, they reached the other side smoothly.

His face suddenly turned black as the bottom of a pot, and he was about to chase after him, but he heard Liu Ruyan say lukewarmly: "Isn't it rare, if you have the ability, you can find a way to cross the river by yourself." ”

Fu Xin was greatly displeased, and immediately ridiculed him, just such a gap in effort, Elder Jiang's disciple Qin Chuan also took the opportunity to jump on the chain.

Immediately followed by Qiu Ying and other sect disciples.

Liu Ruyan saw that Jin stepped on the chain unhurriedly, his body was stable, and his light skills were not bad.

She stopped paying attention to Fu Xin and walked towards the chain.

Dugu Yi stood beside the waterwheel but didn't move, and when he saw Liu Ruyan coming, he stepped forward.

"My junior brother is a little stubborn, but his mind is not bad, I hope the girl doesn't mind, if there is something offended, I will make amends for my junior brother first."

Liu Ruyan glanced at the other party, and there was no trace of politeness in her words, "He is him, you are you, if he kills someone, will it be up to you to pay for his life?" ”

Dugu Yi was stunned.

Liu Ruyan bypassed him and grabbed the chain at the bottom of the waterwheel and prepared to swing up.

He stepped forward a few more steps, "The girl has no internal strength to support herself, I'm afraid she can't cross the river with a chain like them, so it's better to give you a ride." ”

"Shaoxia still has me, and I still have me!" The three Tufuzi hurriedly spoke.

Liu Ruyan's movements in his hands paused slightly, and his eyes wandered between Tufuzi and Dugu Yi.

She chuckled softly, "Who said you can't cross the river without internal strength." ”

With that, she threw the rope in the air, and as the rope clinged to the chain, she jumped up with her feet on the chain below and slid out towards the other side of the river.

The water flow, Kong Ming car, and iron chain form the water passage for ore transportation, but the ingenuity of this project also lies in the inclination of the chains at a certain angle.

After being amazed, Tufuzi followed suit and slid to the other side of the river with the help of a rope.

This time, they learned to be obedient, and they followed Liu Ruyan and Bai Zhi, no matter how they said it, they could also end up safe.
