Long Xilin nodded very approvingly: "Okay, if you need me, just say it." ”

After the two of them were full, Angelica decided to take him to see the waterfall and eat by the way.

Angelica first took Long Xilin to the place where the flour was beaten before, and then told him excitedly that her flour grinder could finally start working.

When she activated the button and showed Long Xilin the noodle grinder, Long Xilin also saw the difference of the noodle grinder.

"Dangdang, this flour grinder, there is no one around to power it, how does it move by itself?"

Angelica smiled: "That's why I had to have this yard before, the reason why the flour grinder can move is because of the waterfall I showed you before, which gave it strength." ”

"Waterfall?"

Long Xilin asked with some curiosity.

Angelica nodded, and after that, she turned off the button, and then pulled Long Xilin, followed the direction of the circuit, and led him all the way to the bottom of the waterfall.

I saw that under the white waterfall, neat brown wheels were installed, and the wheels rotated quickly but in a very orderly manner under the impact of the waterfall.

The sound of the water rushing under the waterfall shows the power of the water.

However, no matter how smart Ren Longxi was, at this moment, he couldn't connect the wheel in front of him with the flour grinder that was humming just now.

He frowned, looked down at the waterfall, and finally found something different under a large rock at the water's edge.

As he stood on the stone, he could faintly feel the vibration coming from beneath the stone.

"Dangdang, is the mystery under this?"

Angelica nodded, she beckoned to Long Xilin, asking Long Xilin to get down from the stone first, and then she walked over and bent down to pick up the stone.

When Long Xi saw it, he hurriedly stepped forward in two steps, picked up the stone one step ahead of her, and put it beside her.

Under the stone, there was a thin plate, and Angelica took out the thin plate, and the mystery inside was revealed.

Inside, there were rows of small gears, driven by the wheels under the waterfall, spinning rapidly.

The wheels stretched out next to each other and stretched out under the invisible ground.

Angelica pointed to the wheels that were spinning rapidly, "Energy is transmitted rapidly through these wheels." ”

After that, she covered the wooden plank, and Long Xilin cooperated to put down the heavy stone, covering the delicate pinion under it tightly.

After that, Angelica pulled Long Xilin and walked back, walked a short distance, and came to a small house.

The house was so small that, strictly speaking, it couldn't be called a house at all.

Moreover, the material used in that house was different from the house next to it, and it was made of stones of regular shape.

Look at the new look, it must have been made recently.

Angelica pointed to the house and said with a mysterious face: "The mystery is inside." ”

Angelica glanced at him and asked, "Do you have iron tools on you?" They were all taken out and placed at the door. ”

Long Xilin was puzzled, but he still untied the dagger, soft sword and other iron tools he was carrying and put them at the door.

After that, Angelica pushed open the door and walked in, taking Long Xilin in.

It was dark in the room, and Angelica took out a flashlight from his bag to light it up.

Under the care of the flashlight, Long Xilin saw a row of coils made of copper wire, constantly rotating.

On either side of the coil were two black stones.
