Qianxi.

Weining State Grass Sea.

The sea of grass is not actually the sea.

It is one of the three major plateau lakes in the Qing Dynasty.

The water is crystal clear and the lake is only a few meters deep. Because a large number of aquatic plants are densely spread under the water, a very spectacular "underwater grassland" has been formed, such as a sea of grass, so it is called the sea of grass.

Beimen Yunfei and the aunt and nephew of the Deng family walked on the wetland trail along the endless and beautiful grass sea. Appreciating the magnificence of nature, overlooking the many migratory birds that soar and chirp in the air, or flirt and play in the water, the three of them are a little intoxicated, indulging in this heaven-like realm, forgetting the bloody wind and rain of the world, and the danger and uncertainty of the road ahead.

When the three of them first walked together, the aunt and nephew of the Deng family and Yunfei from Beimen were strangers. Because they had never met before, their mutual situation was limited to hearsay. Always keep a distance from each other. After a period of ups and downs, taking care of each other, after a little contact and familiarity, the always taciturn, cold and severe, dull and serious Beimen Yunfei has become somewhat funny and lively; Deng Zishan is not as shy and shy as before; Deng Yanling began to put down the city and approach Beimen Yunfei, although she still had some doubts about Beimen Yunfei's ability and ability.

"Brother Yunfei, I don't know martial arts, along the way, I am always a burden to you, if I can also do kung fu, in that way, I can not only protect myself, but also help you. I don't want to learn the kung fu of harming and killing people, I only learn a little kung fu so that people don't hurt me and kill me, can you?" said Deng Zishan a little naïve and naïve. She has lived in the boudoir show house since she was a child, and she only knows anything about the rivers and lakes in her life. If it weren't for this catastrophe at home and having to embark on the road of escape, she would not have been interested in kung fu.

"This... Why don't you let your aunt teach you?" Beimen Yunfei looked at Deng Yanling and said. He knew in his heart that Deng Yanling's words and deeds all revealed her distrust of him, and even her contempt for people by her appearance. He is also well-informed, he is not surprised, he doesn't want to worry about her elder, because she is Deng Zishan's aunt, because the road ahead is still very long, and there are too many risks, he has the time and opportunity to prove who he is. "In addition, kung fu is kung fu, just like the sword on our body, which can defend ourselves and kill people. How can there be any kung fu in the world that can only defend oneself and not kill people? People are involuntarily in the rivers and lakes, and most of the time, you can either be killed or killed, and there is no choice. Especially when you are facing a vicious and powerful enemy, you can only defend yourself by killing the opponent as quickly as possible, right, aunt?"

This is not very pleasant, but it is reasonable. Deng Yanling said, and then said to Deng Zishan: "What kind of kung fu do you learn, I have ...... Of course, Yunfei can protect you, what are you afraid of?"

"Yes, as long as you are covered by a chivalrous woman with strong martial arts like my aunt, I will ensure that you will be in danger, turn evil into good fortune, and become auspicious in trouble. Beimen Yunfei knew that Deng Yanling was so strong and liked to wear a high hat, so he echoed. "I think you should learn a little bit of emergency rescue skills, I'm afraid it can be more practical. Such as whistling, writing notes, sending tokens, shaking torches, knocking Morse codes......"

"Whistling, writing notes, sending tokens, shaking torches, I know all these things, I have never heard of this code. Deng Zishan asked.

Beimen Yunfei originally had nothing to say, just talk casually, and liven up the atmosphere, but he didn't expect Deng Zishan to take it seriously. He had no choice but to give a brief introduction to the Morse Code that he had come into contact with:

"The Morse Code was invented by the American Samuel Morse. It is a time-on-break signal code that expresses different English letters, numbers, and punctuation marks through different sequences. You can transmit the numeric or alphabetical position by tapping twice a second and tapping once a second on the code or the sound of an object, and tell the person who understands the password if you want to say but can't say it, and others want to hear but can't hear it, so as to achieve communication between the two parties in special circumstances. One tap indicates a long one, and two consecutive taps indicate a short one. For example, to call for help: use your hand or tool to tap an object to produce the long and short sound signals of the SOS in the Morse cipher table. The percussion sound is used to indicate the length of the sound, knock (stop for 3 seconds), knock (stop for 3 seconds), knock (stop for 3 seconds) means three long, knock (stop for 1 second), knock (stop for 1 second), knock (stop for 1 second) means three short, knock (stop for 3 seconds), knock (stop for 3 seconds), knock (stop for 3 seconds), indicate three long, so that people who hear this long and short sound know that someone is in distress and needs rescue urgently. ”

Morse code, since the birth of 1837, in which SOS long and short sound code or signal, that is, "send us us" (Send us sus) (Send Us Us) meaning, but also simple and easy to remember, easy to learn and easy to operate, first used in a limited number of people, and then gradually promoted, and finally became a universal distress signal all over the world.

Beimen Yunfei set foot in the East and traveled as far as Western Europe, so he became one of the very few people in the Celestial Empire who knew the Morse code.
