Although Xu Yiyong firmly believes that there can be no inner ghosts, for Sikong Yao, she does not believe in these workers on the dock as deeply as Xu Yiyong, so she still maintains a skeptical attitude.

Xu Yiyong shook his head and said, "Believe me, it will definitely not be our workers who did these things, I think it should be a problem after leaving the dock." ”

Sikong Yao denied: "After the ship left the dock, it made some supplies and went directly to Shenzhen, and after that, it was all transported and stored under the supervision of our own family, and there were no problems during the period, so the biggest suspicion is still here." ”

Sikong Yao is not an unreasonable person, and he did not directly say that the workers on the dock did this thing, but Xu Yiyong also couldn't accept the statement that the incident happened at his dock.

The two sides insisted on their own words, and although there was no fierce confrontation, the smell of gunpowder was already very strong.

Shui Ying seemed to be thinking about something, and if he could figure out what kind of poison it was, he might be a little brows. Yifan looked at the surrounding environment and observed the position of the sentry to see if there were any blind spots that could not be observed.

Bai Xia, on the other hand, walked to the seaside promenade, and the oncoming sea breeze was even stronger, and it was a wave that kept repeating itself in the moonlight.

Suddenly, Bai Xia seemed to understand something, and said: "Actually, if you want to poison a ship docked at the dock, you don't have to go through the border line guarded by the sentry. ”

Sikong Yao looked at Bai Xia and asked, "You mean...... Waterway? ”

Bai Xia nodded and said, "It's not impossible. ”

Xu Yiyong shook his head and vetoed: "Impossible." The waves here are very fast. The boat simply can't get close. Even if they do, they will definitely be exposed to the light, and there is no reason why we can't find out. ”

Bai Xia shrugged his shoulders and said, "If it is poisoned, it is naturally impossible to beat the drum loudly, the fewer people who do this kind of thing, the better, one person is enough." ”

Sikong Yao understood what Bai Xia meant. If you go underwater to the vicinity of the boat, if you sneak up on the boat, it will not be a problem to avoid it at night, even if it is monitored by a lighthouse.

As for this statement, Xu Yiyong once again vetoed: "This is also impossible for you, as you can see, the waves here are very aggressive, and no one can adapt to such a current, even if it is a fish, it can't swim." I don't believe anyone will be able to sneak underwater. ”

Regarding what Xu Yiyong said, Bai Xia was noncommittal. Indeed, he has seen how turbulent the waves at the pier are, no matter how good a person's water nature is. It only comes into contact with the buoyancy and flow of the water, and cannot face the waves. So to say that there are really people who can come by water, it is also incredible. However, despite this, this also shows that the defense line of the dock is not absolutely impenetrable, at least it is a gap, and it cannot be ruled out that someone can actually sneak in with the water. Although the probability is low, it still exists.

Bai Xia looked carefully, trying to find something more, but it was dark at night, and what he could see was very limited, and he couldn't find any clues.

Seeing this, Xu Yiyong knew that Bai Xia was not selfish, so he also came up to watch it together, after all, he was much more familiar with it than Bai Xia here. Although he didn't believe that anyone could sneak over by water, in fact, Xu Yiyong was really convinced of this, and he hadn't carefully surveyed this place before, so if he really missed something, he didn't know.

So Xu Yiyong also followed Bai Xia to watch on the shore, trying to find something, but soon he found that it was impossible at all.

Xu Yiyong gave up this meaningless behavior and said, "Impossible, no one will be able to swim over." ”

Bai Xia pondered and said, "Are there any people around here who are extremely good at water-based?" ”

Xu Yiyong said again: "Give up, no one will be able to do it, if you want to say that there are no people who are familiar with water, the Su family is all good at making tides, and it is not a problem to hold your breath in the water for ten minutes." ”

Hearing this, Bai Xia set his eyes on Su Congshuang, as a member of the Su family, Su Congshuang should know something.

Su Congshuang knew what Bai Xia's eyes meant, so he said: "Brother Bai, the Su family is indeed very good at diving, because they often have to go to the sea to fish, and it is unreasonable to say that they don't know some water-based words, and the ancestors also left some tips to help sneak in the water, but to say that they can pass through this wave, it is really too exaggerated." ”

Xu Yiyong also recognized it at this time, and asked Su Congshuang: "You are from the Su family, right?" If I'm not mistaken, the Su family's generation is an only son, and only the patriarch Su Yecheng has a daughter, you are Su Congshuang? ”

Su Congshuang nodded and said, "It's me." ”

Su Congshuang also approached the railing, looked at the waves that kept lapping, and said: "But such a rapid wave, let alone ten minutes, even if it is ten seconds, it will not last, after the current hits the shore, it will be divided into two layers." The lower layer of the sea will flow back, and if it is intertwined with the waves coming downstream, the water pressure will exceed the limit that the human body can bear, and even the thinner iron plate will be distorted. ”

After getting the affirmation of the Su family, Xu Yiyong also became more and more firm in his opinion, absolutely no one can sneak from underwater, even the Su family, which is known for its water nature, can't do it, then no one else can do it.

As soon as he asked to no avail, Bai Xia had no choice but to give up, it seemed that he couldn't get any clues for the time being, but just when he wanted to give up, Shui Ying suddenly said: "No, I also think that the poisoner should have come from the waterway." ”

Finally made Bai Xia die, and at this moment another person appeared, Xu Yiyong was already a little impatient, and said: "Even the Su family admits that it is impossible for anyone to be able to sneak under such a turbulent current, why don't you give up?" ”

Shui Ying ignored Xu Yiyong, but insisted on her opinion, pointed to the moon, and said, "Brother Bai, look. ”

Bai Xia followed Shui Ying's point, and saw a shallow Kamakula hanging in the air, revealing a faint cold light, and suddenly had an epiphany, and said, "I know Shui Ying, this is the time of day." ”

Sikong Yao didn't understand what Shui Ying and Bai Xia understood, and it wasn't just her, I'm afraid that the others didn't know what these two were messing up with.

Sikong Yao asked, "Bai Xia? What do you know? ”

Bai Xia said: "Xiao Yao, do you know why the sea water rises? ”

Sikong Yao shook his head, obviously not knowing.

And Bai Xia explained: "The tides are caused by the attraction of the moon. Tides are periodical fluctuations in the sea, and the rise and fall of the sea during the day is called 'tide' because the day is morning and the night is night, so the rise and fall of the sea water that occurs during the day is called 'tide'. The gravitational force of the moon causes the sea to rise and fall into high tides, and the greater the gravitational pull of the moon, the more ferocious the tides become. ”

Regarding the reasons for the formation of tidal phenomena, Baoying of the Tang Dynasty and Dou Shumeng, an astronomer in the Great Calendar Period, gave a detailed explanation of this. Dou Shumeng grew up in the eastern part of Zhejiang Province, where tidal phenomena frequently occur, and in the face of the rough sea, a strong desire to explore the mystery always rose in his heart. He habitually appeared on the beach at a fixed time almost every day, staring at the ebb and flow of the water. Long-term observation and practice, a strong interest in knowledge, and the digestion and absorption of the materials of his predecessors, finally made him discover and gain, and systematically summarized it into the book "Haitao Zhi".

The gravitational pull of the moon determines the degree of the tide, in other words, the fluctuation of the tide is pulled by the moon.

"So what?" Sikong Yao still didn't understand what Bai Xia wanted to express.

Shui Ying, who found the problem, explained for Bai Xia: "Let's talk about it, the speed of the water flow is not static, it will change every day, and it is impossible to be as turbulent as it is now." Half a month ago, it was the twentieth day of the eighth month of the lunar calendar, after the Mid-Autumn Festival, the gravitational pull of the moon was the smallest, and the tide would naturally fall with it. ”

Xu Yiyong suddenly came to his senses, but although it worked theoretically, it was still a little unbelievable, and it was too dangerous to sneak underwater on the shore.

Shui Ying continued: "When I was on the island, my grandmother often taught me the gravitational pull of the moon tides, analyzing and grasping the movement of the sea, so I think this poisoner must be a person who is very good at observing celestial phenomena. Know how to take advantage of the low tide of the sea. ”

Bai Xia nodded and said, "It should be someone who is very familiar with the sea, and he knows the changes in the sea well, and this kind of background is accumulated over a long period of time, so it can be judged that this person should be a local resident." ”

Shui Ying said: "And in order to cope with the rise and fall of the tide, the physical strength must be very full, both have a certain amount of experience and sufficient physical strength, the perpetrator should be in the prime of life." ”

Sikong Yao looked at Bai Xia and Shui Ying in disbelief, and after a while, he was able to analyze the perpetrator so thoroughly, the so-called peeping leopard in the tube, probably this is what it means.

Bai Xia then asked, "Brother Xu, I wonder if there is anyone around here who is suspicious?" ”

Xu Yiyong shrugged his shoulders and said: "God knows, how would I know, but the Su family is all good at making tides, and I think I am the most suspicious." The previous innate also proposed to redeem the mackerel farm at a low price, but I refused, several things happened one after another, I think there must be something greasy in this, maybe you can go there to see, maybe there will be some discovery.
