The words are divided into two ends, here Feng Yan found the clown boots and prepared to go to the back of the stage to explore deeply, and the mountain ghost on the other side is not so easy, she now urgently needs to unlock consumables, because the [witch doctor bacteria] on her body is not waiting for anyone, the red line at this moment has climbed to her elbow position, and it is about to reach the big arm, once she climbs to the shoulder, she will die immediately, Feng Yan is victorious without a fight.

This is the price of her unlocking the weapon first and quickly coming to kill Feng Yan, and the game is over if she seizes the opportunity to kill Feng Yan, so naturally she doesn't need to pay attention to this DEBUFF, but now she can't succeed, and what she has to face is a more difficult dilemma - quickly eliminate this DEBUFF.

[Witch Doctor Bacteria] has to be removed by cutting off the arm below the thin line, and it is not impossible to cut it, because fortunately, the mountain ghost also has a bottle of consumables that can instantly restore the severed limbs, as long as the consumables are unlocked before the red line climbs to the shoulder position, the arm can be chopped off, and then immediately restored to remove the DEBUFF perfectly.

The mountain ghost said as he walked towards the southwest: "According to the plot unlocked by the weapon, eighty percent of the plot unlocked by the next consumables is also puzzle-solving. ”

Because he stole the information that Feng Yan talked to the magician, he learned that the mission trigger mechanism would follow the player no matter how he went, so the mountain ghost chose a random direction and left.

Xiao Qingyun has a heart to mind with the mountain ghost, knowing her current mood, so she comforted: "Don't be too anxious, as soon as the plot is triggered, we will calmly solve the mystery step by step, according to the time of climbing from the red line to the present, there are at least 20 minutes to reach the shoulder, as long as we don't mess up, the time should be enough." ”

The mountain ghost exhaled lightly and said, "Well, I believe in your strength. ”

The two switched personalities and unknowingly walked to the venue of the merry-go-round during the conversation.

The mountain ghost looked up at the merry-go-round facility in front of him and said, "I've never seen such a big merry-go-round. ”

The merry-go-round in front of you has 5 floors, the first floor has 81 Trojan horses, the second floor has 27 Trojan horses, the third floor has 9 Trojan horses, the fourth floor has 3 Trojan horses, and the last and top floor is the only Trojan horse, which is a pink unicorn, and at the top of the merry-go-round stands a sign with the name of the Trojan device: Horror Trojan.

While hesitating to go inside and explore, the system narration appears.

[Welcome to the unique five-layer merry-go-round device 'Terror Trojan', which has a total of 121 Trojan horses, and according to legend, each Trojan horse is sealed with an evil spirit, and at night, these sealed evil spirits will come out of the Trojan horse, and they will ride on their sealed wooden horses and let out a lonely and painful groan]

[Side quest triggered: After entering the 'Panic Horse' device, an evil spirit boss will appear on each floor, and after successfully completing the task he assigned, you can go up to another level, and so on until you land on the top floor]

[Completion Reward: If you complete the side quest before the opponent's player, you will immediately get the right to unlock consumables and immediately have the right to view the opponent's 10-minute position]

[Hidden Reward: Complete the side quest and get the reward immediately after successfully reaching the fifth floor, if you choose the task of challenging the unicorn ** generation, you will get the hidden reward]

Feng Yan is a master of exploration, but Xiao Qingyun is not a vulgar person, don't look at Xiao Qingyun's B-level exploration level is lower than Feng Yan's A-level, but she has been staying in B-level for a while, theoretically speaking, she is already on the verge of breaking through the A-level exploration level, only one step away or a high-score performance highlight, and she will be promoted to A-level exploration immediately after the end of the dungeon.

So Feng Yan can think of a reward for extortion, Xiao Qingyun also wants to get, as early as when she accepted the task, she asked for a hidden reward for entering the dungeon through her own way, Ronald promised that as long as she could saw off one of his legs during the first fight with Feng Yan and enter the second item unlocking link, there would be a hidden reward for her.

Later, Feng Yan, who learned about this, scolded Ronald for 1 hour, saying that he was acting on the surface and behind the scenes, saying that he deliberately opened the back door for Xiao Qingyun and provided the convenience of unlocking the weapon quickly, so as to target himself and saw off one of his legs.

Ronald just crossed his arms and listened for 1 hour, and then Feng Yan got tired of scolding and began to reveal his true purpose - to order equipment items or something as spiritual compensation.

Ronald in front of him picked off the cotton in his ear and said, "I'm sorry Brother Yan, I'm Ronald's boss's doppelganger, Uncle McDonald of the Nepal branch, and my nickname is Rock." ”

Then Panshi relied on his extreme endurance and kung fu to successfully let Feng Yan get nothing.

After the narration and the information of the side quests were introduced, the carousel with colorful and cheerful music immediately became dim, and the music became stuttering, and the atmosphere was extremely strange for a while, and the people who were originally empty were each riding a transparent ghost at the moment.

These ghosts all have a hideous appearance of missing arms and legs, looking at Xiao Qingyun's legs a little weak.

Mountain ghost: "Can you do it?" "Just love

Xiao Qingyun swallowed his saliva and nodded: "These ghosts are just the existence of this side quest to set off the atmosphere, and they will not produce substantial attacks, and solving puzzles is the main topic, so it should be no problem." ”

After entering the first layer of the Horror Trojan, before Xiao Qingyun could turn around, the evil spirit leader of the first layer of the Trojan Horse appeared.

"Hello my friend, I am the leader of the evil spirits on the first floor of the Trojan Horse, my name is Ohm......" After a pause, Ohm said: "The embodiment of wisdom." ”

Ohm in front of him was a short, yellow-haired white man who claimed to be the embodiment of wisdom, probably meaning that condensation was the essence.

Xiao Qingyun said simply and clearly: "Please ask the question." ”

Ohm didn't talk nonsense, and with a wave of his hand, three wooden doors appeared on the periphery of the Trojan Horse, and Ohm pointed to these three doors and said: "Two of these three doors are angels and one door is demons, you first pick a door that thinks it is a demon inside." ”

Xiao Qingyun said in a low voice: "Is there a problem with the three doors? ”

Then she randomly chose a doorway on the far left: "I choose this one." ”

Ohm snapped his fingers, ignoring the door on the left that Xiao Qingyun had picked, but opened the door in the middle, and an angel appeared inside.

"As you can see that there is an angel in the middle door, then please answer my question, what is the probability that you will choose the demon between the left and right doors? Why? ”

The mountain ghost said: "This is not simple, it is known that there is an angel in the middle of this door, so there is still an angel gate and a demon door left, and the probability of selection is not half and 50 percent each!" ”

Ohm smiled: "Exploring the strong, are you sure?" ”

Xiao Qingyun switched the control of his body and said: "No, at this moment, the probability that I choose the demon is 33.3% for the left door and 66.6% for the right door, both of which are infinitely looping decimal places, and only one decimal place is taken." ”

Ohm had a weird smile on his face: "It's kind of interesting, it looks like you've heard about the Sanmen question." ”

Xiao Qingyun said: "You are a typical three-door problem, but with slight changes, including the things behind the door and the rules. ”

Ohm nodded: "Hearing and understanding are two different things, please explain in detail why this is the probability." ”

Xiao Qingyun raised the corner of her left mouth slightly to drive the shallow dimples on her face, which meant that she had entered a state of reasoning.

"The three-door problem is a very counterintuitive paradox, like just a mountain...... Just like I deliberately said wrong, from the perspective of ordinary people, there are only two doors left, one demon and one angel, and the probability of choosing a demon can only be 50%, but many people ignore an important point, whether it is before choosing or after you open a door, the foundation of our choice must be based on all three doors and the prerequisites you give. ”

After a pause, Xiao Qingyun said: "Everyone may have their own way of answering the three questions, and I will only do the answers I understand here."

Since there are two angels and one demon in the three doors, then the probability of me picking an angel is 66.6%, and the probability of picking a demon is 33.3%, and your initial request is for me to pick a door with a demon, then when I subjectively pick a demon door based on this fact, the probability is only 33.3%.

When I chose the left door based on this fact, you didn't disclose it, but instead opened a middle door with angels for me, and then you asked me about the probability of the left and right doors choosing the demons, and I had to answer on the basis of the probability of the three doors.

After I picked the left door, you took the initiative to open the middle door without telling me the facts to show the angel, which reduced the 66.6% probability of picking the angel door to 33.3%, but the constant 100% probability is unshakable, which is one of them. I followed your request to find the Demon Gate when you didn't open the door, and there is only a 33.3% chance that it is constant, which is the second one.

Based on the above two basic situations, then the middle door is not picked, and the probability of participating in it can be automatically removed, and the probability of the door on the left is fixed to 33.3% by your prerequisites, then the probability of the door on the right is naturally increased to 66.6%, and the probability of the left and right doors picking the demon is not equal. ”
