Chapter 253 (1/2)

In this circular space is a huge metal machine. Qin yuan and his colleagues are located in the middle of this huge machine.

Looking up, I saw a huge gear and a long chain. It turned from time to time to prove that the huge machine was still running.

This time, Qin yuan was shocked. He seemed to have come to another civilization. He had never seen anything in it.

The machine is very precise. The huge gears as large as ten feet and the parts as small as the fingernail are all closely combined without any delay.

Looking to the distance, this huge machine is supported by nine metal columns with several tens of feet thick. There are various grooves on the columns, and even escalators for people to walk.

The nine columns crisscross each other, and there are also columns supporting and connecting each other to build the skeleton of this huge machine, which is then filled with metal parts of various shapes, large and small.

In the center, there is a huge ring, which is also covered with a ring. There are nine layers of rings inside and outside, which are superimposed with each other.

There is metal connection in the middle, and the smallest ring is larger than the three houses. In the middle of the smallest ring, a dim metal ball is suspended.

Seeing this, Qin Yuan found the trace of the cultivation world. The diameter of this round metal ball is two feet, which emits heat.

The source of hot air here is this metal ball.

Qin Tiangang pointed to the metal ball and said, ”that's the center of the whole huge machine and the place to provide energy. As long as the energy is injected into it, the huge machine will run.

We have tested it with inferior yuan stone before. We can only make it run a little, and it consumes a lot. 10000 inferior yuan stones can make it run for a day.

So later, we simply shut it down. ”

”Dad, I'll try.”

Qin Yuanfei went to the ball and saw that grooves were slowly showing on the ball. As Qin Tiangang said, there were tens of thousands of grooves stacked and arranged.

However, Qin yuan's spiritual strength penetrated into it and found that the interior of the ball was extremely precise, which was probably as good as his Tongtian sword box.

The essence of his Tongtian sword box is more than nine levels of weapons. There are no flying swords. Those flying swords are all energy, so they are endless.

”There are so many grooves?”

After Qin yuan's spiritual strength deepened, he did not fully understand the structure of the ball, but he could see the groove clearly.

It's so dense that it's not clear for a moment. If all these grooves appear and are inlaid with Yuan stones, the ball will become a huge energy body under the integration of arrays.

”Cloud City is much bigger than I thought. Now it seems that it's just the rumble of the center!!

A powerful energy erupted in it. Because of closure and suppression, this energy seemed to be compressed and powerful many times.

Then the whole huge machine began to run, the pinion turned rapidly, and then drove larger gears to the chain... Finally, the whole machine began to run.

Qin yuan hurriedly flew back to Qin Tiangang and said, ”Dad, ten thousand middle grade yuan stones can keep running for a month. This big machine has energy-saving settings, otherwise it will be consumed in half a month.”

So expensive?

Qin Tiangang's eyes are poor. Yes, they are. He thought he was rich in the three ore veins he just got, but now it seems that they are not enough for the center to operate for half a year.

”Dad, are you stupid? You can control the machine by yourself. Look at your token. It should have this function.”

Ang!!

When Qin Yuangang finished, the whole machine suddenly gave out a loud cry like a dragon.

Zazazaza! Gaga, gaga! Boom!
