"Perpetual motion machine?" Hong Siniang finally woke up from the shock, opened her mouth slightly and shook her head: "Isn't it something that even modern times can't realize?"

Jiang Xian whispered: "I mean, its name is a perpetual motion machine, but its nature is not. To put it simply, it is a non-perpetual motion machine called a perpetual motion machine."

The red lady and the eight-armed arhat were stunned.

Ling Xiaozi took a deep breath and said in a deep voice: "The idea of ​​a perpetual motion machine appeared around 1200 AD. It was first in India and later spread to the West. The currently recorded perpetual motion machine is a man named Hennekaul

Made. It’s the same as what we see now, something similar to a waterwheel.”

"Its principle is very simple. A rotating shaft is arranged in the center of the wheel, and movable short rods are installed on the edge of the wheel. An iron ball is installed at one end of each short rod. The ball on the right is farther from the axis than the ball on the left, so the ball on the right is

The rotational torque generated by the ball is greater than the rotational torque generated by the ball on the left. In this way, the wheel will rotate endlessly in the direction pointed by the arrow and drive the machine to rotate. However, he failed."

"No one has ever succeeded in replicating a perpetual motion machine based on this principle... Dear, don't think this is unimportant. Taking this thing out is enough to show that the theory of perpetual motion was first proposed by China! This will blow up the international archaeological community.

!”

The red lady and the Eight-Armed Arhat nodded. Just when they looked elsewhere, they found that Jiang Xian was still looking at the perpetual motion machine in ecstasy. Just when they were about to speak, Jiang Xian pressed his hand and said first: "

I figured something out."

"Everyone, do you remember the golden wheel lock we first saw? And the picture of Hou Yi shooting the sun in the room above?"

Ling Xiaozi was stunned for a moment, and then his eyes lit up: "You mean... after those golden balls fell... they ended up here?"

After saying that, he immediately began to observe carefully. He calculated while looking, and after more than ten seconds, he discovered that these balls were actually the same size as the ones they had seen before!

"In other words, this perpetual motion machine has just been started." Jiang Xian breathed a sigh of relief, lowered his waist and trotted to the edge of the pool. He looked at it and said, "Everyone, look at it!"

Everyone immediately bent over and ran over. As soon as they took a look, everyone's brows were deeply furrowed.

There is not much water in the pool, only about one meter, but the entire pool is two meters deep. You can vaguely see that the bottom of the pool is densely covered with pieces of calcified wood.

"Materials." Ling Xiaozi blinked, slapped his forehead and said, "I understand... this is a processing plant! After the wood is finished, they send it into the channel from here and rush down!"

"No!" Jiang Xian pinched his eyebrows and said slowly: "There is no place to use wood here."

"Look at those houses and the ground, they are all made of stones. It is impossible for stones to float to the water. The method of transporting stones by river is not feasible. And they specially built several hundred-meter ditches, obviously there is a large amount of wood to transport.

, where did the wood go?”

silence.

No one can answer.

It was obvious that a shocking super project had been carried out here, but the essence of the project had disappeared.

"You said... is this river also used to transport that thing?" Hong Siniang frowned and said, "Maybe... it's a boat?"

"Xu Fu seeks the fairy ship!" This time, everyone said in unison. However, as soon as they finished speaking, everyone shook their heads.

"It's still wrong. History has recorded that Xu Fu Xunxian was a fleet. And why was it built here?" "That's right, it's too far from the coast. How can they lead to the sea when they build here?" "There is no need to look far for the near...

…But don’t tell me, such a ship can really hold three thousand boys and girls and various supplies.”

Silence again.

This river must be used to transport something, and that thing is obviously extremely huge, otherwise it would not have taken manpower to build a canal of more than a thousand meters. But... what is it?

"Go find Mozi." After a while, Jiang Xian shook his head and said, "Only he has the answer. Let's go down first."

Everyone nodded, and the group carefully bent down and chose the river bank opposite the monkey crane.

Walking in such a majestic underground palace, silence follows you like a shadow. Every step is filled with the dust of history. Walking on the stairs piled up by countless lives, a feeling of vicissitudes of life arises spontaneously.

Walking down the wide white marble stairs, you can see a row of stone houses built against the wall as far as the eye can see. Twenty meters away from the door is the vast canal. The evil-proof sculptures seem to tell the vicissitudes of the years. And when they stepped down the stairs

, finally saw the incredibly big ape crane.

It was about a few hundred meters away from them. It didn't feel that there was an uninvited guest here. It slowly shook its short tail and its huge palms passed by slowly and unhurriedly. Some stone houses that had long been shaky were simply moved in this direction.

It collapsed under the huge force and turned into several meters large rocks falling down.

But to this behemoth, it was just a watermelon dropped.

"What a fucking monster..." Ling Xiaozi's lips were trembling: "Have you mastered the inner elixir?"

Shhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh.

Things, and... they can't break through the defense.

I'm afraid even a bullet wouldn't be able to hit this kind of monster. Once it's discovered... you can only wish for good luck.

Jiang Xian shook his head and forced himself to look away from the monster. He waved his hand and rushed into a nearby room when Yuan He turned his head. Then he looked back.

The underground waterfall is extremely spectacular when viewed from this angle.

The 100-meter waterfalls on both sides dropped huge curtains of water, rumbling into the canal. A curtain of dim water stretched out forty to fifty meters high, and underneath the waterfall was a huge cave.

That should be the place where the ancestors of the Ape Crane lived... Jiang Xian looked at it for a moment and frowned slightly. He suddenly realized... that the shape of the hole was not right.

It doesn't look like it was dug manually. Through the telescope, you can see that the inside is full of pits and very damp. But... its cutouts appear round.

It's like... something is protruding from it?

At this moment, everyone entered the stone house. Jiang Xian withdrew his gaze, pointed to the top of his head, and said, "I took a few glances just now, and there are pulleys installed on the top of each stone house. And, look here."

He pointed to the stone bed - in this windless place, there is no possibility of weathering of stones. The stone house has not changed after more than two thousand years. The bed and table are all available. And just on the bed... No, there are even many rooms.

There are still some white hairs left everywhere. But most of them have faded and turned into light gold.

"Is this... Yuanhe's home?" Hong Siniang took a deep breath, then shook her head and said, "No, Yuanhe's body cannot enter at all. It is built according to human proportions..."

"What if it's a baby ape crane?" Before he could finish speaking, Jiang Xian interrupted: "Ape cranes can't be that big when they are born. Their food is bats and zombie fish. And zombie fish... this river

I don’t know how many there are, but their lethality to the little apes and cranes is fatal.”

Ling Xiaozi narrowed his eyes: "Do you think...this is the nursery of the Ape Crane Group?"

Jiang Xian nodded: "Yes, you can see that the coat color has turned light golden. It has been at least several years. Let's put it this way, Ape Crane can't get in here. But... we have to be careful, there are young Ape Crane

Put here."

Everyone took a deep breath and nodded solemnly.

The little ape crane is not scary, but the scary thing is...if it screams and attracts the monster, they won't be able to escape at all!

This kind of stone house is of no use to the monster. Even if it dares not demolish it for fear of the little ape crane, once it is blocked in the stone house, it will be the same as waiting for death.

If a worker wants to do his job well, he must first sharpen his tools. Before the final exploration, all dangerous points must be found. No one thought this was a waste of time. After everyone nodded, Jiang Xian took out a marker and casually marked it on the ground.

The painting says: "Mozi's room should be in the middle section."

He drew two vertical lines to refer to the canal, and pointed in the middle of the canal: "As a master builder of this huge project, he needs to be in a place where he can be informed in time before and after. Moreover, it should be at the highest level,

He had to overlook the project."

"The rooms of the peasants are not particular. Moreover, these stone houses are built layer by layer like terraces. The way we want to go is at the top!" He marked four areas of different heights on both sides and used a marker to

He nodded heavily at the highest point: "I did a rough calculation and found that the highest point of the residence here is more than thirty meters. This height... is very good!"

At ten meters, you might be able to see the monkey crane with just a quick glance. This is a sub-dangerous height.

Twenty meters is exactly the height of the ancestor of the ape crane, within the range of its eyes. This is the most dangerous height!

And more than thirty meters is the distance that it needs to raise its head to see. For such a huge creature, especially in an environment where food is relatively scarce, it will not make too many meaningless actions. Moreover, this is also an ordinary ape and crane.

A place that requires climbing. If discovered, they would have some time to retreat.

Dark under the lamp.

The Red Lady and the Eight-Armed Arhat immediately figured this out and glanced at Jiang Xian with admiration. Even they had not thought of such a detail. Even though it was only ten meters away, it was probably a matter of life and death.

"It's amazing..." Hong Siniang sighed faintly: "If I had a choice, I might just follow the house on the ground and leave directly. A new generation will replace the old, awesome."

"I just thought about it a little more." Jiang Xian shook his head and said solemnly: "You are not allowed to separate and take a rest. In ten minutes, we will start a comprehensive exploration!"
Chapter completed!
