Facing the sea, the Lighthouse of hope is ahead.

"Fang Tang, you are not going to tell me that Feifei is hiding in the lighthouse, are you?"

"Why not hide in the lighthouse?"

Huawu Island Lighthouse in the distance will flash every 15 seconds, and the radio tower standing on one side of the lighthouse is constantly releasing signals.

This is the bright light on the sea, the most silent guardian on the whole route from the East China Sea to the sea of Japan.

Lao Zhao is very familiar with the materials of the second largest lighthouse in the Far East. After all, Huawu lighthouse is definitely the most famous building on this remote island.

But if you want to hide two people there for 19 years, it's really incredible.

"With Hai haoying's shrewdness, how could he ignore such an obvious building? He must have searched the whole island. And it's 19 years... "Lao Zhao murmured.

Fang Tang said with a faint smile: "at night on October 13, 2001, you saw Tong Feifei under the cliff. What was the situation at that time?"

This matter, in the office building checkpoint, Lao Zhao has described in detail.

At this time, he recalled again: "Feifei appeared on the sea, like a ghost, head down, hanging upside down in the waves. At that time, I could see her head blinking at me under the sea... By the way, she was also full of fluorescence, very beautiful."

When Li nianshui heard this, he was shocked and stared at the blonde: "you, what are you talking about? Did you come to our village nineteen years ago? "

In terms of age, this blonde might have been a little girl nineteen years ago.

In the field, Li nianshui knew nothing about Lao Zhao's identity. Fang Qingqing coughed: "Mr. Li, don't interrupt!"

Li nianshui Oh, or looking at the blonde Zhao Zhongcheng.

It seems that he is very concerned about Tong Feifei.

Fang Tang smiles at Lao Zhao: "when I heard your description at that time, I inferred that the Feifei you saw was actually projected. Now when I think about it carefully, the fluorescence on Feifei's body can prove this."

As soon as Zhao patted his head, his blonde hair shook: "yes, it's similar to the projection in the office building. Alas, I was too confused."

"At that time, virtual projection technology was too high-end, you can't think of it, but you shouldn't ignore the location of Feifei."

Fang Tang said, "you were at the bottom of the cliff. According to the position of light and shadow that Feifei appeared in the sea, she must be directly opposite the cliff. Because the light source propagates in a straight line, only the direction of the lighthouse is possible."

This is the simplest optical principle. Zhao clapped his hands again: "yes, only the shadow cast from the lighthouse can appear under the cliff. Below this is a triangular Bay. Other places will be covered by mountains, so the light can't pass through. Damn it, I didn't expect that. "

"All these years, you always regard Feifei as a ghost. You always believe that she is guiding you to solve the case." Fang Tang shook his head: "it's a pity that there are no ghosts in this world."

Zhao grabbed his blonde hair: "but, why is Feifei's projection upside down?"

Fang Tang looked at the gradually calm sea: "it's very simple, it's the reflection caused by the diffraction of light, which also proves my conjecture from another aspect. When the lighthouse project enters the sea, because the sea water diffracts, it's like a mirage."

To this extent, it is enough to prove that Tong Feifei was hiding in the lighthouse at that time.

But Lao Zhao was puzzled again: "no, it's still not right. The time is not right. According to your reasoning, Feifei and Fang LAN stole the Dragon King coffin after October 13. When I saw Feifei's projection, she should still be in Hai haoying's laboratory!"

Fang Tang nodded: "this is also a big bug in my reasoning at that time. I couldn't understand it until I heard the conversation between Hai haoying and Li nianshui just now under the cliff... I just wanted to understand it."

He looked at the silent Li nianshui: "did you take the Feifei replica from the laboratory?"

Everyone is shocked!

Li nianshui had a good understanding of Fang Tang's skills, but he nodded calmly.

Fang Tang continued: "you were not old at that time, but you were already Hai haoying's helper."

Li nianshui sighed softly: "it's not only me, my father, but also several uncles of Hai family. They are all under Hai haoying's hands. Maybe it's because I graduated from high school. I'm one of the few people on the island with a little degree. So he thinks highly of me. "In that closed environment, Hai haoying needs a person who knows some basic scientific knowledge as a helper. There are not many people he can trust and control. Naturally, Li nianshui is the best choice.

Fang Tang shook his head: "but you are different from Hai Chao Sheng. An upright young man, of course, repels such things from the bottom of his heart."

Li nianshui clenched his fist: "it's not just rejection. When I found that Hai haoying was actually conducting a living experiment, my first idea was to call the police."

"But you dare not act rashly, because the whole village, ha ha, even the whole island, has been brainwashed by Hai haoying, the son of the Dragon King."

Li nianshui gritted his teeth: "yes, Hai haoying knows how to control us very well. Some of the people who follow him are brainwashed. They really regard him as a God. Others are for the sake of interests, but I can't help it. My whole family is controlled by him."

Fang Tang was silent for a moment: "you also participated in the sacrifice on October 13, 2000?"

Li nianshui nodded heavily: "it was my first time to participate in the sacrifice ceremony. Hai haoying liked this kind of ceremony very much, in order to confuse the villagers."

"You saw Feifei in the sacrifice and the tragic death of her parents."

"Feifei, haihaoying's No.10 experimental body, was quickly reproduced by the experiment." Li nianshui closed his eyes in pain: "but at that time, I didn't have the courage to fight against the devil. What I could do was to make the resurrected Feifei feel better. In that year, Hai haoying did more than 200 experiments on her..."

When he heard this, he couldn't help stepping on the body of Hao Ying in the fishing net, The corpse's head was creaking under his feet.

Li nianshui continued: "there is no abnormal infection on Feifei. This is the first time. Hai haoying is very excited and even pulled me to drink that day. But at that time, I have made a decision to save Feifei even to death!"

Fang Tang said: "you and Tong Feifei had only one chance to escape at that time. That's the next sacrifice! That was when Hai haoying's lab guard was the weakest. "

2001 October 13, 2008, the night of Fang Lan's bloody wedding.

Li nianshui escaped from the laboratory with Feifei at that time.

Fang Tang recalled all kinds of clues and fragments in his brain and said in a deep voice: "if I guess well, the first place you two hide after you escape from the laboratory is the secret tunnel of the office building!"

Li nianshui looked at Fang Tang in shock again.

He couldn't understand why the young man knew everything. It's like seeing it with your own eyes.

Fang Tang said with a smile: "don't look at me like this. It's easy to think that the villagers on the island have been brainwashed. It's impossible to hide in the villagers' homes. As for places like the police station, Hai haoying may have controlled them for a long time."

"Only the new office building, with large space and secret roads, was the most dangerous place, but also the best place to hide at that time."

Li nianshui sighed: "yes, because the Dragon King temple was demolished, Hai haoying opened up the room in the middle of the new office building and made it into another secret laboratory. At the beginning of the construction, he asked several uncles and my father to dig underground organs."

Fang Tang sighed: "the sacrifice on October 13, 2001 has not started yet. You and Feifei hide in the secret Road, and want to wait until dawn, and take advantage of the most busy time to leave the island by boat. But before the plan started, you saw the scene of haichaosheng killing your father in the office building! "

Li nianshui's throat trembled: "yes, my father died in the big office. I was next door at that time."

Separated by a wall, he watched his close relatives die.

Li nianshui, a high school student at that time, experienced the darkest night.
