"Don't lose your strength!" Bo Xiaosan is very envious of Hong Tao's figure, people in this era are slightly lower in height, Chen Mingen's statement is a five-foot man, and there is no such thing as a seven-foot man. According to Song Qi's calculation, it should be about 1.6 meters, which is a standard figure. The height of the Tan family is not the same, like Chen Mingen and Chen Qihong, the height of the northern people is close to 1.7 meters, and the height of the southerners like Huang Hai and Bofu is short.

"Not by the body, but by the technique, I'll teach you when I get back! But I don't teach in vain, you have to teach me something, like how to see the time with the stars and the moon! Hong Tao didn't want to teach them judo, but wanted to use this as an excuse to ask for knowledge. The Tan family is very protective of their knowledge, and Bo Fu and Huang Hai have instructed Hong Tao several times that if other fishing boats pass by, then stop going to the ground cage and not let others see it, even the Tan family.

Hong Tao feels that there is nothing wrong with this habit, and there is patent protection in later generations, so why should the things he invented be free for others to use? But there is one place where Hong Tao feels that the ancients are not suitable, that is, they would rather bring the technology to the coffin than write books and talk about it, which is a bit wasteful. These techniques are valuable lessons that have been slowly summed up over several generations, and even if there is no heir in your own family, you can still leave a name for teaching others, so why let it be lost forever.

"You don't need to change it, I'll teach you now, it's nothing, anyone will! Look at the seven-star official ...... "Bo Xiaosan is much more generous than Hong Tao, and he doesn't need Hong Tao to think about it at all, pointing to the starry sky above his head, and letting Hong Tao find the Big Dipper."

"The head of the spoon is upright, that is, in the middle of the night, the head of the spoon is horizontal, it is the wild chicken, and if it is erected a little, it is Pingdan, and it should be dawn." Bo Xiaosan spoke very simply, he didn't know the principle or anything, he only knew the mantra passed down from the previous generation, and there was no adaptation.

According to his method, Hong Tao roughly measured it, and found the mystery in it. Quite simply, they connected the two stars of the Big Dipper, Tianshu and Tianxuan, with a line, and the extension of this straight line used to be the North Star. Then take the North Star as the center of the disk, and the extension cord of the Big Dipper as the hand, just like looking at a watch, this needle points to where it is at what time, which is very scientific. Because the North Star is basically located above the North Pole, the position changes slightly, but it will not change significantly, which means that the center of the disk has not moved, and the closer to the equator, the higher the accuracy of this method and the smaller the error.

According to this method, Hong Tao tried, hey, it really worked, when the pointer pointed to the position of half past four, a trace of blue and white was revealed on the sea level in the east, and the error was only more than ten minutes. If you make a disc, draw a scale on it, and find the north and south, this is an ancient clock! If you can calculate the difference between seasons and latitude, there is basically no big error!

This method is very similar to the principle of using constellation navigation in the West, and the ancient Chinese have long used it, but unfortunately no one has come out to summarize this method into a set of theories that anyone can use, and the result is preempted by Westerners.

"Made! No, when Lao Tzu has kung fu, first make navigation a science, I will open classes, write books, and let you rob them! When I die, I seal my books in jars and bury them with me, and after hundreds or thousands of years, maybe they will be dug up. One look, hey! Invented by the Chinese, there is a picture and a truth! Hey, hey, hey, hey, he......y, he

"Tao Yanzi, what is your strange name? It's ugly! Bo Xiaoer was awakened by Hong Tao's gloomy laughter in his sleep, looking at Hong Tao who was looking up and smiling, and frowned, this foreigner is good anywhere, but he often suffers from neuropathy, which is not normal.

"The bird knows the ambition of the bird! You know the hair! Xiao Jiao, get up! "Bo Xiaoer interrupted his imagination, Hong Tao gritted his teeth with hatred, and landed as soon as he took off in his thoughts, he couldn't bear it, he directly took Bo Jiao to get angry, your grandpa interrupted me, I will kick you!

After washing his face and eating a few mouthfuls of taro, the sky was already bright, and a patch of red was already revealed in the east, and the sun was about to show his head. The two boats raised their half-sails, gradually widened the distance, and began to continue the rope with the rolling hook tied to the bamboo tube into the sea. This thing is a little more cumbersome than going down to the cage, and when you hook it, you not only have to wear the fish meat on each hook, but you also have to be careful not to entangle the strand with the main line.

After the hook was finished, the fiery red sun also jumped out from under the sea level, revealing most of his face and secretly looking at the two sneaky boats, and using his own light to illuminate the bamboo tube floating on the sea surface to reflect the straight light, probably to remind the fish underwater, don't come, there are a few bad guys here!

The hook is finished, what are you doing? You can't sit on a boat and bask in the sun, can you? No, fishing is not so leisurely, after the hook, you have to take out a small hook, wear the shrimp to fish, and the fish caught is used as a bait for the hook and crab pot. If there are no big fish for half a day, you have to change the bait again to keep the bait smelling of fresh meat.

The water depth here is more than 80 meters, Hong Tao used up his coil of hemp rope, and also snatched the hemp rope of Bojiao, and found the bottom of the sea together. However, this time he was unlucky, the hook hung on the reef at the bottom of the sea, and he could only pull the rope off, not only did he not catch the fish, but also lost a hook and more than 20 meters of rope. Bo Xiaoer and Bo Xiaosan already have several fish on their side, all of them are mackerel more than a foot long, this thing belongs to the upper fish, it is everywhere, it is worthless and not delicious.

Hong Tao is unwilling to fail, and he is not willing to catch the same mackerel as others, only catching fish that others can't catch is the ability! He is playing, others are working, not a mentality at all. It doesn't matter if the rope is broken, since he knows that the water is about deep, then he doesn't sink the hook completely to the bottom, stops when it reaches more than 70 meters, and then stands on the boat and pulls the rope up and down.

Is there such a fish? There must be, otherwise the angler should be depressed to death. As soon as he shook off a dozen times, Hong Tao felt that the rope was sinking, not hanging to the bottom, because there was something pulling underneath.

"Hey, hey, hey...... Boy, dare to break my rope and cut my hook, and see if I don't fish out your whole family! The water is too deep, and the rope is too heavy, Hong Tao can't feel how heavy this fish is, but judging from the strength of its struggle to escape, it shouldn't be too small, otherwise it won't be able to pull the dozens of meters of hemp rope, or the soaked hemp rope.
