Chapter 180 (1/2)

On the elevator, there is an operation panel.

Du Qingke clapped his hands tentatively. The voice control switch in the elevator room was really activated and the indicator light was really on.

”It seems that the elevator has electricity. This is much easier to do. ”

Du Qingke was not happy.

However, the digital button of the operation panel is more complex.

The numbers on these buttons are not ordinary Arabic numbers. If you look at these numbers carefully, you will find that these numbers are actually arranged by Morse code.

Morse code is an early form of digital communication, but it is different from the modern binary code which only uses zero and one or two states. Its code includes five kinds: dot, stroke, pause between dots and strokes, short pause between each character, medium pause between each word and long pause between sentences.

Morse code played an important role in early radio, and it was necessary for every radio communicator to know.

Due to the progress of communication technology, Morse code has been stopped using in 1999. However, it still has a wide range of applications in real life due to its minimum bandwidth and technical and artistic characteristics.

”Dot, stroke, dot, dot, stroke, stroke, pause, dot......”

Du Qingke tried hard to recall some knowledge of Morse code.

”I can't remember some knowledge. It's luck

On the buttons symbolizing dot, stroke, pause and character distance, Du Qingke made regular touch and click.

”Ding!”

The elevator door closes automatically and starts to work!

Du Qingke has correctly solved the Morse code. Now, the elevator is being transported up the cliff at a high speed.

Taking the elevator, Du Qingke had some doubts.

This elevator, obviously, was built later.

But who built it?

Or is it built in wanzhang cliff?

Such a complex technology, such a large amount of work, one person can not complete.

If you want to build an elevator connecting wanzhang cliff, this kind of project needs a complete engineering team, and it will take a long time to build.

”It seems that the situation of the Canaan source quarry is much more complicated than I thought.”

Sitting in the elevator, Du Qingke was full of thoughts.

At the moment, the fighting is still fierce in the uranium mining area.

Originally, the Knights of cheetah mercenary regiment are very powerful.

But, because it was drugged.

Half of the fighting power of the mercenaries has been brought into full play.

Mountain bandits, relying on great advantage, will kill the mercenaries one by one.

Nelson's eyes were red and angry!

”Fangya, you will not come to a good end! How dare you deal with my cheetah mercenary regiment like this! You'll wait for crazy revenge

As the commander of cavalry company, Nelson's strength is also very strong!

Nelson's accomplishments, has reached: diamond level, specializing in fighting spirit, is a fighter!

”Kill!”

Nelson fought with the tusk commander at the same time, forcing his own injury down.

”Dong!”

The strength of the tusk commander is not bad!

Tusk commander is also an extraordinary person in the middle level of diamond rank!

The extraordinary occupation of tusk commander is: ancient warrior.

”Nelson, you've done it yourself! If not, you are too greedy! I'm not going to attack you cheetah mercenaries! ”

said the tusk commander coldly.

”I hate it! I hate it! I should have killed all of you mountain bandits

Company commander Nelson, roaring.

”Die! You want to kill us? ”

The tusk commander picked up the eight foot long circular machete and cut Nelson's stomach open.
