The instrument is roughly cylindrical, the surface is hollowed, the eyelets are carved into the pattern of auspicious clouds, surrounded by three relief unicorns, one is flying and domineering, but it is entangled in iron chains; the other lowered his eyebrows and bowed his head, but his fierce face was revealed; The last one was around a Dan furnace. They seem to symbolize the three-legged triumph of the demon, the demon slayer and the demon refiner.

There are two ichthyosaurs entwined above the instrument, as if they are at war and intimacy, and the glimmer of the spar in the instrument shines through, casting light spots on the four walls through the holes, and the whole stone chamber looks like a dream.

Only a very small number of demons know about the existence of this city-destroying instrument, and the demon exterminator dug three feet into the ground to find it, but he never thought that it was buried under the dry well on the outskirts of T City. Once triggered, traps will activate in the four corners of the Imperial City adjacent to T City, swallowing the entire city underground.

The destruction of a city is a signal for all the demons to rise up and fight!

The old man trembled and shook the horns of the three unicorns, and the instrument began to rotate and open, and the light became more and more intense, and there was a glass jade bottle inside it, which was filled with mercury, and a mysterious luminous crystal floated, the outline of which could be faintly seen. Underneath the bottle is a circle with a groove in the middle, just the size to set that hedron, as long as it is embedded, the circle will be triggered, and then it will be the end of the country...... Of course, it will also be the end of the demon.

The old man rubbed the bottle for a long time, hesitating to break it and take out the trigger hedron inside. At this time, he saw a line of small characters engraved on the side of the magic circle, not madeinchina, but a sentence specially written by the wise man after completing the instrument: "People of the future generations please think twice, once this mechanism is triggered, their world, our world, will go to hell from now on!" ”

"Wise man, wise man, what would you choose if you were here?" The old man looked at the hedron floating in the bottle and said, "Hundreds of years have passed, and the world has not gotten better, but worse...... What the hell am I going to do! ”

After standing there for a long time, the old man still couldn't bear to do it, he turned off the instrument and returned the way he came. When I came back to the real world, I felt as if I was much older.

The old man spent the day in a humble little hotel, and this day he did not get a drop of water, but sat there and smoked sullenly. He pondered silently, the destruction of this country was all in his thoughts, the choice was heavy, and he was giving himself a reason not to destroy the world.

After thinking for a long time, the old man walked outside to find a telephone hall, took out a small notebook from his body, and pressed the number on it to Lu Su's mobile phone not very skillfully, but found that he couldn't get through (Lu Su's mobile phone was trampled on by Jinduan!). Then he pulled it out to Chu Qianque, the phone was connected and there was a noisy voice, and there was a faint sound of music from the song and swallow dance, and Chu Qianque said loudly: "Hey, who!" ”

"It's me!"

"Ha, stinky old man, where have you gone...... I heard you're far away. ”

"The kid isn't here, I want to talk to him."

"He's not here. Are you in a hurry? ”

"Yes!"

"Wait a minute, I'll tell Henry to go and talk to Brother Lu, just make this call?"

"Yes, I'll wait."

Twenty minutes later, the payphone rang, and Lu Su's voice said, "Old man, where are you?" ”

"Don't ask about this......"

"Ha, isn't T T City, the area code will betray you! What are you doing over there, bring us some osmanthus flowers...... Are the buns over there delicious? ”

"Oh, I'll buy it when I see it...... That, I'd like to talk to you. ”

"Yes!" Lu Su listened quietly on the other end of the phone.

"I'm just making small talk, don't take it seriously...... I've heard people say that the end of the world is coming, what if...... It's just that if you kid have the right to decide whether the end of the world will come or not, what will you choose? ”…,

Lu Su still heard something unusual, and asked tentatively: "Old man, are you going to do something big?" ”

"Let's gossip, don't talk about anything else."

"If I had a choice, I would choose not to let it come."

"Why?"

"The world sucks, I admit it! But it hasn't gotten to the point where it should be abandoned, and since it's not yet to this extent, let's use our power to change it! ”

"Woo......"

"What the hell is wrong with you, old man, why do you suddenly ask such a thing."

"Nothing, nothing, I'll bring you a specialty."

After speaking, the old man hung up the phone with a "click", and Lu Su's bold words seemed to sound very naïve, but they seemed to make his heavy mood feel relieved a lot.

As he walked back, he was surprised to see a couple taking pictures in front of a ruined temple, waving scissor hands and shouting. When he noticed the old man walking by, the young man beckoned and said, "Hey, old man, can you take a group photo of us?" ”

"You call me?"

"Yes, yes, hurry up! Come and take a picture for us! ”

"I don't have the skills."

"Why are you tired of the old thing, do me a favor and get rid of your meat, come here."

He walked over very reluctantly, but when he took the camera in his hand, the old man suddenly thought of something, and his eyes suddenly became gloomy when he looked at the couple......

A few days later, the bodies of a man and a woman were found in a river in T City, and the murderer did it so neatly that there was no trace of it at all. The deceased had nothing of value on him, the motive for the murder was speculated to be a love killing, and the investigation got bogged down in a messy interpersonal relationship, which could only be shelved as a headless case.

Half a month later, the headquarters of the demon slayer N City received a photo, which was a strange instrument, and there was no word other than that. Zhang Yi, who was in charge of investigating this matter, investigated for a long time, and the traces on both the envelope and the photos were handled cleanly, and he didn't know who sent it......

However, after checking the information for a long time, Zhang Yi understood the meaning of this instrument, the legend of the wise man left a mechanism to destroy the city, this thing on the photo is very similar to the sporadic description in the internal information of the demon slayer, this description is still the wise man himself said a sentence "Double dragon swimming, three Lin gathered." After falling into the city, the long night is forever silent! "The organization had searched for it several times without success, and at one time thought it was just a fiction made up by wise men to be scary, but now it has appeared!

Zhang Yi's final conclusion was that it seemed that there was a person demonstrating against them, and that person held the secret to the destruction of the country! This threat caused the organization to panic for a long time, and the most direct consequence was that they stopped the hunt for the fugitive demons in N City, and small characters like Zhang Wei who were forced to get involved in the war were able to save their lives.

Of course, that's for later.

The old man left for City C the next day, and met the talkative guy on the train again, and the two sat face to face. This time he became reticent, and the old man asked him what was wrong.

The guy said that he actually went to T City to meet a netizen, and after two years of bitter love, he found out that it was a man when he met. He said with a sad face: "I feel that my life is meaningless, I really want to die." ”

"Why do young people talk about death all day long, as the so-called 'three points of qi are good in a thousand ways, and everything is impermanent and everything is off', life is more important than anything else."

The young man sighed faintly: "I'm really depressed now, if only the end of the world would really come." ”

The old man said, "The end of the world will not come." ”

"Sir, that's not what you say."

"It's really up to me, and I won't come if I say I won't come. It's okay to live it. The old man smiled.

……

On the fifth day of training, Lu Su had reached four minutes of breath-holding time. At that time, Jin Duan and Willie were counting down on the shore, and when the count reached 0, he broke through the water and gasped for breath. …,

"Congratulations, four minutes!" Professor Wei said, "This training is here, after all, holding your breath is not the purpose of training. Five days to reach this level is not bad for a newcomer. ”

"Ha, I didn't expect me to really do it!" Lu Su was so excited that he didn't know why.

The three people on the shore looked at each other, and Willie said, "Big brother, tell you another secret." ”

"Huh?"

"Actually, you've reached eight minutes!"

Jin Duan shouted from the side: "Wow, eight minutes!" Sue, you're so strong...... Hey, didn't you just say four minutes? ”

"That's because ......"

"You don't have to act." Lu Su was not too surprised, "I sent it out a long time ago, the timer was passive, and one second was actually two seconds." ”

"Ha, Sue, how did you find out?"

"It's strange that you didn't let me practice at home that day, you have no reason to stop me. Later, I lay in bed and tried to hold my breath, and calculated the time, and each time it reached more than five minutes, I understood that you had colluded to lie to me, and there was a problem with the timer. ”

"Leave them alone, it's my idea." "It's a lie, but it's a white lie, so you can push your potential, don't be angry." ”

"I'm not angry! Eight minutes ...... I'm amazing. ”

"This is just the first step, there is nothing to be proud of." Professor Wei said.

"Shall I start the second phase of training tomorrow?"

Professor Wei shook his head: "I said that we should turn the limit into a habit. Tomorrow and the day after tomorrow, you will still practice here, and you will not be required to break through the limit, just consolidate in eight minutes. ”

Willie tugged at her father's sleeve, Professor Willie lowered his head, and Willie whispered a few words in his ear. Then Professor Wei straightened up and said, "Three days, three more days of training!" ”

"You're just trying to let Willie play in the water for one more day."

"Pity the hearts of parents all over the world, if only you understood my good intentions."

"It's so careless."

"It's also for your good, after three days of consolidation, we move on to the second phase of training...... I'll prepare the equipment for you for the next two days. ”

"Alright then!"

Jin Duan and Willy high-fived, and Jin Duan said happily: "Tomorrow we will set up a platform to dive and play." ”

The first stage of training has been effective, Lu Su is still very happy, on the way back has been very interested, never dreamed that he could reach the time of eight minutes of underwater lurking, if he trained for another ten days and half a month, it would be no problem to go to the diving world to win gold and silver...... Of course, this is just YY, and the demon goes to show his face purely to find death.

When he got home, he said, "I'll make you something delicious tonight......

When the door opened, the two suddenly saw a person sitting in the room smoking, and they exclaimed together: "Old man, you're back!" ”
