Chen Zheng listened to Shanshan's words and did not answer, what is science? He couldn't explain it clearly.

If you can't explain things clearly, you can't explain them randomly, and if you say too much, you will lose them.

Chen Zheng found a wooden stick, stuck it straight into the sand, and began to measure the length of the stick and the shadow.

After jotting down the length of the measurement, Chen Zheng began to remember.

The day he was caught by the Fusang dwarf was the winter solstice, and at the time of the winter solstice, the sun was on the Tropic of Capricorn, and now after these days, the sun should move north.

He definitely can't grasp the specific angle, and can only estimate a rough idea.

The estimated angle of the sun and the length of the sticks and shadows were calculated using a set of formulas that I had just come up with, and the latitude of the place was roughly calculated.

As for the latitude of Dongyang County, it can only be estimated by impression.

Chen is a carpenter, and he is usually very sensitive to data such as size, so he calculated the latitude of Dongyang County based on his impression.

The longitude is then measured.

Chen Zheng's biological clock is very stable, and the time to wake up every day is very fixed, and he found that the sun comes out half an hour earlier than Dongyang County, that is, a difference of one hour, and the relative position of the longitude between the two is about 15°.

The relative positions of latitude and longitude are out, and the orientation is also found.

According to Chen Zheng's request, Xu Sheng went to find a magnetic needle, and a simple compass was ready.

Installing the compass on the rudder and adjusting the angle, Chen Zheng shouted: "Sailors, go to sea!" ”

The first time he drove such a "high-level" ship, Xu Sheng was still very excited, although at the beginning, he could not fully control it, but after all, he was a child who grew up by the sea, and his talent at sea seemed to be innate, and after fiddling with it a few times, he mastered the skills.

According to the angle of the compass pointer set by Chen Zheng, the wooden boat of the unit was moving quickly.

Chen Zheng calculated some of the ship's speed, and if the direction of Dongyang County he calculated earlier was not bad, then it would not take three days to see the coastline of Dongyang County.

Sail fast during the day, and naturally rest at night.

The sky is clear, the crescent moon is crooked, and the stars are shining.

Chen Zheng found the location of the North Star, and recalculated it according to the knowledge of astronomy, which was almost the same as his previous calculation, and then he slept with peace of mind.

On the third day of sailing at sea like this, Chen Zheng could no longer sit still, standing on the deck, holding on to the railing, looking into the distance.

"Look, there's a ship coming up ahead!" Sansa shouted suddenly.

Chen Zheng hurriedly walked over, stood on tiptoe, and looked into the distance, and sure enough, there was a ship heading in their direction.

At first, it was difficult to see who was on board, but due to the speed of Chen Zheng's dhow, the relative position between the two was rapidly approaching.

After finally seeing the figure on the other party's boat clearly, Chen Zheng's face changed greatly, and he shouted to Xusheng: "Turn the rudder quickly, it's a bandit!" ”

When Xu Sheng heard it, he was also shocked, he often heard the people on the island talk about the horror of the pirates, and now that he has encountered it, he is really scared in his heart.

By the time Xusheng reacted and began to turn the rudder, the two were already very close.

At a distance of several zhang, even the hideous faces of the Shanghai bandits on the ship could be seen clearly.

Similarly, the pirates also saw the situation on Chen Zheng's ship clearly.

"There's a woman on board!"

"Flower Girl Drips!"

"Haha, whoever gets on the boat first, who gets on the boat first!"

The other side suddenly made a lot of noise, and some of the words he said were also unbearable.

Shanshan He had seen this kind of scene before, and she was frightened for a while, and Chen Zheng took a step forward and blocked her behind.

Fortunately, the speed of the dhow was fast enough, and the pirates could not catch up for a while; However, the small boat of the pirates is light and dexterous, and although they can't catch up, they can't get rid of it.

After a while, the pirates were obviously impatient, and ropes with iron claws were thrown over and hooked onto the gang of the wooden boat.

The speed of the wooden boat was obviously affected, and the pirates behind were also pulling the rope hard, and the distance between the two ships was constantly shortening.

Chen Zheng wanted to go over and cut the rope, but as soon as he was close, there were bandits shooting him with bows and arrows from behind, so he had to stand far away and not get close.

The three people on board were so anxious that they couldn't do anything but watch as the pirates' ship got closer and closer.

Chen Zheng copied a wooden stick from the side and held it in his hand, always ready to do his best.

It seemed like a long time, but it was actually a short time, and the pirates' ship finally landed on the dhow.

The pirates cheered and jumped on board.

"I'm the first, and the girl is mine!"

The first pirate who got on the boat didn't pay attention to Chen Zheng at all, and walked straight towards Shanshan, with an obscene look on his face.

Chen Zheng stood in front of Shanshan, squeezing out a vicious expression and glaring at the pirates.

The pirate was simply disdainful of Chen Zheng, and said contemptuously: "Stinky boy, get out of the way!" When the master is finished, I'll get you again! ”

"If you want to bully her, you have to step over my corpse first!" Chen Zheng is not afraid of danger.

In the face of this time, fear and begging for mercy are useless, they will only increase the pleasure of the other party's perversion.

The bandit frowned, and snorted coldly: "Then get you first, and I'm going to get this girl when I'm done!" ”

After speaking, the pirates approached Chen Zheng and the others!

At this moment, Chen Zheng suddenly felt a trace of cool air passing by his face, and almost at the same time, a steel needle was inserted into the bandit's chest!

The bandit didn't understand why a steel needle suddenly shot at him, and he looked down to see something.

Chen Zheng was also taken aback, but he reacted very quickly, knowing that now was not the time to be stunned, he raised the wooden stick in his hand and smashed it on the bandit's head.

Bang!

Crit! Chen Zheng himself is not small, and this time he directly opened the head of the bandit, even if he didn't die, he would be stupid.

With a plop, the pirates fell to the ground, a little unclear.

At this time, Chen Zheng had time to look back and see what had happened.

Shanshan also turned around to look, but her little face turned pale with fright, and she said in despair: "Brother Chen, why are there so many ships in front, are they all sea bandits?" Are we not going to survive? ”

While asking, Shanshan looked at Chen Zheng, but saw the other party's smile.

This smile was very faint, but it made Shanshan feel very warm, but this warm smile was obviously not for her.

Sansa looked across again, and there was a young woman standing on the boat opposite, and the woman also had a warm smile on her face.

"Sanshan, we're saved!" Chen Zhengdao's tone was obviously much more relaxed.

As soon as the words fell, Shanshan was surprised to see that the woman on the opposite boat jumped directly and flew over from the opposite side.

Could this be a fairy?
