Song Xiaofang decided to start the operation the next morning, because before that, he had to prepare something.

At breakfast the next day, Lao Zhang happily said to everyone

"Great, everyone, just announced that the sea closure has been lifted, and a boat will come to pick us up in the afternoon, and the police will also come."

After hearing the news, Su Yong's joy was overflowing

"Great! It's finally time to get out of this hellish place! What bullshit gold, I don't want it! ”

At this time, Song Xiaofang stood up with a serious face, looking at his expression, there should be something big to announce.

Song Xiaofang's face was very sad, and he said in a very solemn tone

"Then, before the police come, let me find out the real culprit who has committed a heinous crime on this island."

After hearing this, Fang Kexin asked very excitedly

"What? Does Little Fang know who the murderer is? ”

Su Yong felt that there was no need for that, and said reluctantly

"The police are coming in the afternoon, why should you be a hero here, if you fail, you will be a shame in front of your woman."

After speaking, she glanced at Su Yalan, Su Yalan "snorted", gave him a big look, and said

"I have confidence in Xiao Fang, so he won't fail like you!"

Song Xiaofang didn't care about Su Yong's remarks, completely treated him like air, and began his own reasoning

"The murderer is among us, and the murderer is you!" As he spoke, he stretched out his index finger and pointed at Yu Dongting fiercely.

When everyone heard this, they instinctively moved in the direction away from Yu Dongting as if they were hiding from the plague, looking at him in horror.

Yu Dongting's face was still as sunny as a confident smile

"Hehe, little fang, is this our plan?"

Although the others didn't know what Yu Dongting's so-called plan was, everyone refused to believe that he would be the murderer, so Fang Kexin hurriedly spoke for Yu Dongting

"Impossible, Xiao Fang, how can Mr. Yu be the murderer? He's been desperately trying to find the truth. ”

Yu Dongting raised his hand confidently, signaling that Fang Kexin didn't need to worry, and he still said in a slow voice

"Xiao Fang, even if I have a chance to kill Guo Xiang, Zuo Hongyi, and Xiao Yanran, but everyone at the table has a chance, and in Han Chen's case, it is impossible for me to kill someone, besides, you have to tell me, how did I create that secret room?"

Yu Dongting's series of questions were all within Song Xiaofang's expectations, and in the face of Yu Dongting's geological questions, Song Xiaofang also answered in an orderly manner

"It's very simple, you were the first to rush into the room, and you secretly put the key in Guan Shuang's hand while pretending to examine the corpse, and faked it as a secret room; As for Han Chen's case, the conclusion that he died for an hour was told by you, if in fact he died an hour ago, or even more ago, then any of us would have a chance to kill him, but you are the only one who can make this kind of fake proof of the time of death. ”

"How so? Is it really Mr. Yu? Liang Yanyan said in disbelief

"Papapa..." Yu Dongting smiled and applauded after hearing this, and continued

"Sounds like perfect reasoning, but what proof do you have?"

"Yes!" Song Xiaofang said categorically.

Yu Dongting's face became ugly for a moment, but he immediately regained his smile

"Really? Then I really want to know, what is the evidence that doesn't exist? ”

Song Xiaofang didn't back down and said, "It's a fingerprint!" ”

"What? Fingerprint? ”

"That's right, you weren't wearing gloves when you put the key in Guan Shuang's hand, so there should be your fingerprints on it!"

"Ridiculous!" Hearing Song Xiaofang say this, Yu Dongting finally couldn't help it, and stood up, and the smile on his face was replaced by anger

"I was trying to make sure that Guan Shuang was holding a house key, so I used it to unlock it, and of course it had my fingerprints on it! This is what you call evidence? Bored. ”

Saying that he was about to leave, Song Xiaofang hurriedly grabbed Yu Dongting's shoulder from behind and shouted

"Are you going to run away?"

Yu Dongting was completely angry, turned around and pushed Song Xiaofang

"What am I running from? If you say I'm guilty, come up with more convincing evidence, or shut up! ”

Song Xiaofang was pushed by Yu Dongting and hit the oil painting on the wall directly, and the painting also fell down slowly, and at this time, a note fell out from the back of the frame.

"Little Fang, are you alright?" Su Yalan shouted, ran to Song Xiaofang's side, and hurriedly checked if he was injured.

Song Xiaofang shook his head, stood up, and tried to stop Yu Dongting

"Yu Dongting!"

As if he hadn't heard, Yu Dongting swaggered towards the second floor without looking back

"Anyway, the police are coming in the afternoon, just leave it to them then, your detective game is over, look at the feelings of the past few days, I won't sue you for slander!"

"Hey, stop me!" Song Xiaofang shouted and ran up as well.

"Little Fang, don't be impulsive." Su Yalan was afraid that the two of them would do it again, so she shouted and followed.

"W-what can I do about this?" Lao Zhang seemed a little at a loss, and he didn't know what to do for a while, so he followed.

Su Yong's eyes were quick, and he quickly picked up the note, and slowly opened it, so that Fang Xin came over and tried to see the contents of the note

"What? What is written on it? ”

Seeing that Fang Kexin also wanted to see the content of the note, Su Yong hurriedly put the note in his pocket and hurriedly covered it up

"Nothing, nothing, boring stuff."

said that he also went back to the room, but whether it was Su Yong's tone, demeanor, or pace, all revealed extremely strong excitement.

When passing by Yu Dongting's room, he also heard the quarrel of several people, and Su Yong sneered

"Hmph, a bunch of idiots, what about how many people die? Who is the murderer and what? The gold is mine! ”

Fifteen minutes later, under a certain tree in the forest of Baile Island, Su Yong was holding a shovel and digging the soil on the ground in ecstasy, he was so excited that his hands trembled with excitement, and his mouth kept shouting

"Gold, gold is mine."

At this time, a black shadow slowly approached from behind Su Yong, and carefully took out the kitchen knife that had just been stolen, and the black shadow was also very excited and excited

"Just kill you, and it's all over!"

Now the black shadow is less than three steps away from Su Yong, and he raises the kitchen knife high, as long as this knife is swung, the black shadow's grudge over the past few years will disappear.

"Su Yong, be careful!" At this time, Song Xiaofang's voice suddenly came.

Su Yong was startled, instinctively turned around, saw a hideous face, held the kitchen knife high, and hurriedly picked up the shovel in his hand to resist.

The black shadow knew that he had fallen into a trap, but now he had no other choice, he had to kill Su Yong no matter what, and swung two knives in a row, wanting to kill him.

Su Yong shouted for help while waving the shovel indiscriminately, although his arm was still scratched, but he inadvertently knocked out the kitchen knife in the black shadow's hand, Song Xiaofang and Lao Zhang saw this and hurriedly rushed forward.

Song Xiaofang kicked away the kitchen knife, and cooperated with Lao Zhang to press the black shadow to the ground, Su Yong sat on the ground in shock, trembling, and then Qiqi, Lawyer Liang, and Su Yalan also rushed over

Su Yong knew that there was no danger, so he stood up tremblingly, screamed, and kicked the murderer viciously a few times at the murderer who was pressed to the ground

"! Kill me? You want to kill me? Stand up and kill now! “

Song Xiaofang pressed the murderer with all his might, but he really couldn't spare his hand to stop Su Yong, and shouted desperately

"Enough! Su Yong! Stop, don't kick! ”

Su Yong kicked a few more times before he stopped unwillingly and asked

"Song Xiaofang, what's the matter? Didn't you say that Yu Dongting was the murderer? Why did Fang Kexin kill me too? ”

After Fang Kexin was kicked by Su Yong a few times, he didn't have the strength to resist, so Song Xiaofang let go of his hand a little and slowly stood up to explain

"No, all the murders on the island were done by Fang Kexin, and he was the one who sent the invitation, it was just a scene between me and Mr. Yu in the morning, of course, and Mr. Zhang, I deliberately let him say that the police were coming in the afternoon, so that he thought it would be too late if he didn't do it, and forced him to show his feet."

When Su Yong heard this, he angrily took out the note in his trouser pocket and questioned Song Xiaofang loudly

"What? Could it be that the golden location written on this is also fake? ”

Song Xiaofang couldn't help but answer with a smile when he saw him so excited

"yes, that's what I put behind the painting last night."

After Su Yong heard this, he was so angry that he tore up the note, threw it on the ground, and scolded through gritted teeth

"What the fuck, you're fucking using me as bait?"

If Su Yong scolded himself like this before, Song Xiaofang would definitely fight with him again, but this time he was really inauthentic, and he felt that Su Yong's appearance was very funny now, so he didn't care too much, and shrugged his shoulders as if he had nothing to do with him

"Please, I just put a note, as for who will be the bait, how do I know?"

"You!" Su Yong still wanted to curse, but Song Xiaofang interrupted

"Don't forget, I said a long time ago that the person who killed Guo Xiang couldn't be someone from me who went out to look for Yalan at that time, Lao Zhang, Yu Dongting, and Xiao Yanran, but you still believe that Yu Dongting is the murderer, what can I do?"

Speaking of this, Song Xiaofang realized that Yu Dongting didn't come over

"Huh? Where did he go? ”

Su Yong was already so angry with Song Xiaofang that he would definitely beat him up if he wasn't injured, but now he could only stare at Song Xiaofang there.

Song Xiaofang put away his smile, turned his gaze to Fang Kexin on the ground, and said in an unquestionable tone

"Fang Kexin, you have been caught by us, it is time to confess, right?"

Fang Kexin's expression was as stiff as a sculpture, but he still denied it

"Nope! I just saw Su Yong digging for gold here, so I wanted to kill him when I saw the wealth, and I didn't kill the others! ”

Song Xiaofang looked at Fang Kexin with great disappointment and shook his head helplessly

"Fang Kexin, be free and easy, and confess your guilt."

Fang Kexin sneered a few times

"Hehe, I didn't kill anyone at all, what crime do I confess? If you have to say that I killed the person, you must at least explain how I killed Guan Shuang and Han Chen, right? I simply don't have enough time! ”

"You have!" Song Xiaofang categorically denied it, glanced around at the others again, and said with a sigh

"Okay, then I'll explain how the murderer completed these two murders, everyone follow me."

Su Yalan picked up the kitchen knife that fell to the ground and followed, Song Xiaofang looked at her thoughtfully, hesitated for a few seconds, and didn't say anything.

Song Xiaofang took everyone to the bank of the river where Yu Dongting found an abnormality yesterday, pointed to the other side of the river, and asked Lao Zhang

"Mr. Zhang, did you say that if you go around and walk to the opposite laboratory, it will take an hour, but if you go directly to the bridge, it will only take a few minutes, right?"

Lao Zhang said while holding Fang Kexin stiffly

"Well, yes, but the bridge is ruined, and it's impossible for anyone to swim through it with such cold water."

Song Xiaofang shook his head

"You don't need to swim over, just walk over."

Su Yong laughed when he heard this

"How do you walk there? The fog on the surface of this lake is very large, do you want to ride the clouds over it? Hahahaha! ”

Song Xiaofang glanced at him, didn't say much, smiled confidently, and jumped into the river without hesitation.

"Hey, Song Xiaofang! You are crazy? ”

Except for Su Yalan, everyone was taken aback by Song Xiaofang's actions.

Including Su Yong, they also shouted

"Is this guy crazy, he..." Only then did Su Yong realize that Song Xiaofang was not washed away by the river, or even sank, but stood smoothly on the water.

Su Yong looked at Song Xiaofang dumbfounded, knelt directly on the ground with weak legs, and said unbelievably

"Is it really cloudy?"

Song Xiaofang raised his voice and shouted

"Take a closer look! How the hell did the murderer accomplish this impossible crime! ”

The sunrise on the island always comes very late, at this time, a red glow appeared in the sky, slowly expanding its range, the sun slowly rose, and the fog on the river gradually dispersed, then everyone saw clearly that Song Xiaofang was not standing on the river, but on a shining ice bridge.

Everyone was speechless for a moment when they were shocked by the bridge, and Kexin's expressions became more and more complicated.

"Hey, hey, Song Xiaofang, how did you get this? How could there suddenly be an extra bridge? ”

Song Xiaofang said with emotion as if an artist was showing his works

"This bridge is a fantasy magic trick that can only be done in such extremely bad weather, right, can it be new?"

Fang Kexin was still silent, and Kiki asked

"So, little fang, how did this bridge come about?"

Song Xiaofang began his own explanation

"The night before Xiao Yanran and Han Chen were killed, Kexin used the trees on both sides of the riverbank, tied a lot of ropes back and forth, and then put the grass and small branches and other things prepared in advance on the ropes, and then covered them with snow, and repeated this operation little by little, and soon reached the opposite bank, and then cut the ropes, and after a night of freezing, the ice bridge was completed."

Lao Zhang said dumbfounded

"It's amazing, if you use this bridge, you can really get to the other side in 2 minutes."

Song Xiaofang nodded

"That's right, last night Yalan and I used this method to build this ice bridge overnight." He jumped twice as he spoke, "It seems that the load is very good." ”

He added

"At that time, Kexin pretended to throw a plastic bag full of poison gas, in fact, he used his ice bridge to kill Han Chen, he left for almost ten minutes, in terms of time, it was absolutely time, and at that time, only you left the villa, that is, only you had time to kill! So the murderer is you, and there will be no one else. ”

As he spoke, Song Xiaofang couldn't help but admire Ke Xin

"Mr. Fang, what a shocking technique."

"So, what about Guan Shuang's case? How did he get out of the locked room? ”

Song Xiaofang lowered his head and pondered for a while, then slowly began to speak

"On this point, it was Mr. Yu who gave me a hint."

"Yu Dongting? What hints can he give you? ”

Song Xiaofang still ignored Su Yong's question, walked back to the shore, and began to speak directly

"Mr. Yu told me that there are many chemicals that look exactly the same on the surface, but are actually very different, so I figured out the meaning of the room number, in the periodic table, each element corresponds to a number, therefore, the room number, represents the material of the metal door, for example, my room is number 28, so it is nickel."

"But, little fang, so what?" Su Yalan asked

Song Xiaofang smiled slightly and began to explain the technique of the secret room

"Guan Shuang's room is No. 50, Mr. Yu told me that the corresponding element is tin, and its melting point is about 231.9 degrees, I remember that there is a liquefied gas welding gun used to make a fire in the warehouse, and that kind of thing can make it melt."

"You don't think you want to say that Fang Kexin melted the gate and went in, right? So how do you restore the door to its original state? Liang Yanyan asked suspiciously

"That's right, that's the subtlety of the technique."

Song Xiaofang began the final explanation

"First of all, you can use heat-resistant materials such as gypsum to make a model of a part of the door of the frost room, and then cover the door with a heat-insulating cloth or tape, and use the liquefied gas welding torch mentioned before to melt off a part of the door, tin is very heat-resistant, or it will melt in a short time, and a hole will be opened in the door, and then it is more important, if the hole is completely melted open, the tin will flow into the room, and when it melts to the point of almost, you have to stop, and then use a heated screwdriver and other tools, Melt the weakest place between the blocks a little bit, so that you can take off a whole piece of tin, and then put your hand in, open the door lock from the inside, and you can go in, and then there is the escape room, after killing people, he locks the door from the outside, puts the same size of the cast block plate prepared in advance on the hole just now, and then fills the gap with molten tin water little by little, and then fixes the plaster model just made on the outside of the door, pours tin water into it from above, and waits for the molding, and then removes the model, and it is finished. From the outside, it is impossible to find that the door has been manipulated in this way. ”

After everyone heard this divine reasoning, they were surprised and didn't know what to say, and after a while, Liang Yanyan asked

"But... Can it really go so smoothly? ”

"I'm sure he's done a lot of drills before to make it so perfect."

"That's not right!" Su Yong suddenly thought of something and interjected

"The order of our rooms is determined by drawing lots, if Guan Shuang doesn't catch No. 50, then how can he be killed?"

Su Yong's question was indeed very correct, and everyone focused on Song Xiaofang again, waiting for his answer, Song Xiaofang sighed and said

"Don't forget, who is the one who proposes to cast lots?"

In retrospect, the person who proposed to draw lots was indeed Ke Kexin, but despite this, how could he control it?

Su Yalan asked puzzled

"Xiao Fang, then how did he guarantee that Guan Shuang would be drawn to the 50th? Is it to pray to God and worship Buddha? ”
