The black Audi A4 is driving towards the city center in the misty night of Moscow, and the traffic in Moscow is still dense at midnight, and almost all the metropolises in the world are cities that never sleep, busy 24 hours a day, making people feel that it is time to sleep.

Cheng Mo sat in the co-pilot and looked at the map of Moscow provided by Google Maps, and Li Jiting introduced to Cheng Mo while driving: "There are a total of nine railway stations in Moscow, each of which goes in a different direction, and the nine railway stations are basically distributed on the ring line of Metro Line 5. We are now going to Komsomolskaya Square, which the Russians also call the Three Railway Station Square, and there are three large railway stations that go to St. Petersburg, Novgorod, Murmansk and other cities. Although there are nine railway stations in Moscow, there is no need to worry about making mistakes, because Russian railway stations are just as straightforward as the character of Russians, and they are named after the end points, and in other provinces, they are called Moscow railway stations when they go to Moscow, and in the same way, in Moscow, they go to St. Petersburg and enter St. Petersburg, and when they go to Belarus, they go to Belorusskaya railway stations, and it's that simple and rude..."

"Trains from Moscow to Cao County and from Moscow to the capital depart from the Yaroslavl railway station, which is on Komsomolsk Square, next to the St. Petersburg railway station, and all trains to the Northern regions of Russia, Veliky Rostov, the Urals, the Siberian region, the Far East depart from the Yaroslavl railway station .... These include the international intermodal carriage to Cao County, and the K20 to our country, all of which depart from this railway station...."

The word "international intermodal carriage?" was a little unfamiliar to Cheng Mo, so he asked, but he didn't look up, still staring at the map.

"Yes, the international intermodal carriage, from Moscow to Cao County, although it is said to be a train, but in fact it is only a green car, this carriage hangs at the end of the train from Moscow to Vladivostok, twice a month, after arriving in Vladivostok, there will be a special locomotive to drag this carriage to Vladivostok ....."

For Cheng Mo, who has never been out of the house, things like "international intermodal carriages" are a little unexpected, and he instantly made up a somewhat bleak picture in his mind.

"In fact, 10 years ago, there were two routes from Moscow to Cao County, in addition to what I just said, there is also a carriage that hangs behind the K20 to our country, the train first arrived in Mukden, and in Mukden changed to K27 times to go to Cao County Liujing, but in 2010 this route from Moscow to Cao County was suspended, 05 and 08 years, when I took K19, I saw these two Russian railway carriages on the platform of Fengtian Station twice, but all this has become history, only the one that does not pass through our country is left.... Li Jiting said meaningfully.

Cheng Mo can roughly guess some reasons, but he doesn't care too much about it, if it weren't for the task to be completed at the moment, he wouldn't even care about the country of Cao County, of course, studying history, that's another matter.

"Speaking of which, this international intermodal carriage can really apply for the Guinness World Records, it is the world's longest train running distance, and it is also the only passenger train with a one-way journey of more than 10,000 kilometers. From Moscow to Liujing, the whole journey is 10,267 kilometers, and the train is scheduled to run for nine days and nine nights, but because the Caoxian train is generally delayed, this train will take ten days or even longer..... This train crosses the Tumen River estuary at the junction of China, North Korea and Russia, only a few hundred meters away from our country but does not pass through our country at all, at the junction of the three countries, it is really 'the rooster cries and hears the three countries, and the dog barks and frightens the three Xinjiangs'......"

"Is there only one carriage? Will the goal be too obvious? If I were a Cao County agent, I would take Sylkov on a K20, or find a way to go to Vladivostok first, and then drive or walk to the Cao County border....." Cheng Mo asked with a frown.

Li Jiting shook his head, "It's not realistic to drive from Moscow to Vladivostok, the condition of the Far East highway is not very good, after arriving in Siberia, the road vehicles are sparse and empty, there are many checkpoint nodes, the target will be more obvious, it is easier to be discovered, Russian logistics are also controlled by gangsters, if you want to drive, or hide in a truck and run to Vladivostok, you can't escape the monitoring of Russian gangsters.... The most suitable way is to take a train, and the nearest 240 train to Vladivostok is the one that departs from the 2nd, and will be hung on the international intermodal carriage to Cao County, which is operated by Cao County Railway, the carriage is from Cao County, and the conductor is also from Cao County, so it is easier to mix in it.... However, it is also possible to take the K20 as you said, but it is a big risk for Shirkov to pass through our country, and the K20 will have a trip the day after tomorrow, one day earlier than the 240..... Tickets for both trains are currently sold out..... I think Sylkov will definitely take one of these two cars....."

"Didn't the people of Cao County seek help from the Russian gangs?"

"If the people of Cao County come up with 600 million US dollars, the Russian gangsters will definitely not mind helping the people of Cao County, but unfortunately the people of Cao County are being sanctioned by the economy, and 600 million US dollars in cash is really an unaffordable figure for them... The Russian underworld has already issued a reward of five million US dollars, no matter who can catch Shirkov, they can get a reward of five million US dollars, and now, their Cao County people are hunters walking in the dark forest full of robbers with night pearls..."

Five million dollars can't make any waves in the world, but in the world of the world, five million is enough to change the fate of ordinary people, and you can imagine how many undercurrents and gangsters are frantically looking for Shirkov in Moscow today.

Cheng Mo himself was also tempted by Li Jiting to join the army looking for Shirkov.

"It's here!" Li Jiting parked his car on the side of the road, and the strange buildings with white walls and black tiles stood on the other side of the black iron fence, and the towering towers and majestic trapezoidal main buildings on the left side reminded people of the lavish architecture of the Moscow Kremlin and the rigorous style of the churches of the Russian North.

All in all, it's a building you can't forget when you see it.

"Is it okay to stop here?" Cheng Mo turned his head and asked Li Jiting.

"It doesn't matter, the traffic police in Moscow won't post tickets everywhere in the middle of the night. After speaking, Li Jiting turned off the fire, pushed the door and got out of the car.

Lin Zhinuo, who was incarnated by Cheng Mo, also got out of the car.

"Do you want to go to the square?" asked Li Jiting, looking at the empty square in front of the Yaroslavl railway station not far away.

Cheng Mo shook his head and stood in place and spun around.

Li Jiting didn't know what Cheng Mo was doing, and watched Cheng Mo turn around with his eyes closed, facing the direction of the Yaroslav Railway Station again, without saying a word.

After a while, seeing that Cheng Mo was still silent and his eyes were not opened, Li Jiting asked with great interest, "What are you doing here?"

Cheng Mo didn't answer, his mind turned the map near the Yaroslav train into three-dimensional buildings, as if there was a huge Moscow sand table growing wildly in his mind, and the sun was moving on those sand tables, and the shadows changed with the sun, and the flow of people and vehicles also changed..... All the road information began to spread towards the Yaroslavl train where he was stationed, intersections, foot traffic, traffic lights, metro passages, bus stops.... This data is all collected into the fastest and most secure path.

When all the calculations were completed, after a while, Cheng Mo opened his eyes, looked at the street lamp above his head that was as bright as a torch, and said softly: "I gridded the map of Moscow, calculated the shortest route to the railway station at each location in the shortest time according to the wayfinding algorithm, and then built a mathematical model, using calculation methods and screening conditions to find the most suitable hiding place." ”

Li Jiting, who was smoking, opened his mouth in surprise when he heard Cheng Mo's words, and stood up against the body of the body, causing all the cigarette ash that had not been broken to fall on the toes of his shoes, "Pathfinding algorithm? Is it an algorithm based on Manhattan distance?"

"Yes! is the application of Manhattan distance in the game. Cheng Mo nodded.

"Sounds pretty lofty..... Is it really as good as a computer in the brain?

"This is also a point that I have been researching, the computing speed and capacity of my carrier's brain are obviously much higher than my ontology, in general, the brain of the proprioception is only good at decision-making, learning, and imagination, and memory storage is actually not very good at it..... But the carrier is different, the memory storage is comparable to a computer, all the pictures seen can remember the details, and the memory ability is thousands of times that of the ontology..... I watched a movie with a carrier, and I can ..... accurately"

"Alright, alright..... Don't popularize science, I know all this, you just say whether the pathfinding algorithm is useful!" Li Jiting waved his hand and interrupted Cheng Mo to report his research results.

"Whether it's useful or not, I don't know if I don't give it a try, I calculated two sets of results, one is the A Star algorithm, which is advantageous enough to use a heuristic function (Heuristic Function), and the other is the Dijkstra algorithm, which simply belongs to the unheuristic version of the A Star algorithm....."

"My dear apprentice, let's get to the point!" Li Jiting shrugged his shoulders and said helplessly.

"Oh, I thought you'd be interested in this!" Cheng Mo said quietly.

"I can still discuss physics with you, and I learn math very generally..... If I'm good at math, I'd be happy to be a sniper who stands in the distance and fires a dark arrow....."

Almost all math skills are ranged attack skills, which can strengthen bows, arrows, The combat ability of all long-range weapons of guns, an ordinary sniper rifle can exert hundreds or even thousands of times more power under the blessing of carrier mathematical skills, in addition to mathematical skills also have a bonus to melee ability, although unlike physical skills are physical damage skills, in fact, they are also very powerful, but most carriers who are good at mathematical skills will choose to be long-range attackers, after all, it is too cool to hide in a few kilometers or even dozens of kilometers away.

"I calculated two sets of results, the first is the optimal solution under human beings, near the Yaroslavl railway station, there are fourteen places that are the most suitable places to hide, these places are places with a large flow of people, it is easy to escape, travel, and you can reach the Yaroslav railway station by walking. The second set is the optimal solution above the human being, and there are as many as fifty-nine points....."

"Below humans, above humans?"

"The optimal connection under human beings is the path suitable for ordinary people to escape, and above human beings is the path suitable for the escape of the superhuman carrier...."

"You're the most gifted enforcer I've ever met..... It's a .....shame for someone like me to work entirely on intelligence," Li Jiting shook his head and applauded in admiration.

"Actually, there is nothing magical, many people just don't connect some seemingly unrelated things with the investigation work, I just have a little more knowledge.... And all this would not have been possible without the carrier......"

"No matter what, silently, you are my lucky boy! at least you have made our search have a goal, don't talk nonsense, let's start looking now!" Li Jiting pulled the car door and said.

"The problem is that these places are all high-rise, and it is difficult for us to go door-to-door, and even if we can ignore some floors, the workload is amazing.... We have limited time and limited manpower...."

Cheng Mo looked at Li Jiting and didn't continue, but the meaning was already obvious, this was an impossible task.
