Civil aviation airliner is flying at an altitude of 10,000 meters.
From Beijing to New York, Cao Yusheng inquired about the route information and chose this plane specially.
Maps are flat, but the Earth is round. The route of the aircraft needs to consider many factors, it is not as simple as two points and one line.
Cao Yusheng chose this international flight to take the Arctic route.
The route of this flight looks like a high-throwing curve on the map. It starts from Beijing and goes north, passes through the Arctic Circle, and finally lands at Kennedy Airport in New York.
The reason why I chose this flight is because it will land once in Khabarovsk on the bank of Heilongjiang to pick up some guests.
Because of this, Cao Yusheng was able to take a look at Heilongjiang from the air.
At this moment, the plane had already descended into the clouds, and this meandering river had already appeared outside the window.
Seen from the air, the third largest river in China is still as calm as ever.
It was September, the earth was in autumn, the river was black, the banks were yellow, and it was a desolate scene.
Although Cao Yusheng had expected what he saw before him, but when he really saw this river, the thoughts in his mind were far less calm than the river water.
Thirty years ago, he traveled all over the northeast of the Dragon City under the Heilongjiang River and collected some information.
They were all folklore, which he wrote down in a thick notebook, on which he also made some speculations based on historical materials.
It's a pity that Cao's family suffered an accident fifteen years ago, and a fire reduced this notebook to ashes.
Based on the memory in his mind now, this black water dragon city should have been built during the peak period of the "Shizhang Prosperous Age" of the Great Jin Dynasty.
That is, the period when Jin Shizong Wanyanyong and Jin Zhangzong Wanyanjing were in power, from 1161 to 1208 AD.
Influenced by Han culture, the Jurchen people believe that the Chinese dragon originates from Kunlun and is divided into three branches, namely the Southern Dragon, the Central Dragon and the Northern Dragon. The Greater Xing'an Mountains and the Outer Xing'an Mountains happen to belong to the North Dragon Dragon Vessel.
During the reign of Jin Shizong Wan Yanyong, a huge underground space in Heilongjiang was discovered by mountain people and reported to the court.
Wan Yanyong thought at the time that this place happened to be located in the North Dragon's vein, and the landform was very peculiar. It was God's bestowal on the Jurchen "Longxing Land".
So the emperor decided to build a huge underground city on the dragon's veins, with dragon guards inside to restrain the dragon's veins, so as to protect the Jin Dynasty from generation to generation.
This city is called "Black Water Dragon City".
Cao Yusheng did not know how many people and how much money was used at that time, but it can be vaguely seen from the legend that it was almost the power of the whole country of the Dajin Dynasty.
In history, many countries were subjugated because of such things, such as the Great Wall of the Qin Dynasty and the Suzhou-Hangzhou Grand Canal of the Sui Dynasty.
Although this kind of large-scale project has great achievements, it was unbearable for the productivity at that time.
And the Black Water Dragon City is different from the Great Wall and canals in nature.
The Great Wall and canals are national projects with practical functions, and the Suzhou-Hangzhou Grand Canal is still functioning today.
The Black Water Dragon City only represents the secret ambition of the two emperors. There are no historic sites to pay tribute to, and no value to cash in. So there are only a few sporadic legends left so far.
Thirty years ago, Cao Yusheng traveled all over the Northeast. With his ability at that time, he could only know so much.
But now, Miao Guangqi is far away in the United States, but he claims to have found the Black Water Dragon City.
This is obviously abnormal, and this abnormality made Cao Yusheng alert.
Although the two hadn't seen each other for nearly 30 years, and they had less and less contact over the years, Cao Yusheng always had a deep impression of Miao Guangqi.
Cao Yusheng had to admit that, even if there was a talent explosion in Liemen 30 years ago, and Lin Leshan, Zhang Lianhai, Su Tongji, and Yun Yuexin were born, he, Miao Guangqi, was still the brightest among the stars. .
Even Lin Leshan, the later leader of Liemen, was not as popular as Miao Guangqi in Liemen's evaluation before the duel.
It's a pity that in that duel, Lin Leshan defeated Miao Guangqi with the arrogant and unreasonable "Three Great Martial Arts".
From then on, Cao Yusheng couldn't see through Miao Guangqi.
After staying with him in the Northeast for a year, Cao Yusheng vaguely felt that this person was no longer close to him, and the two parted ways from then on.
This time, what is the intention of this second sworn brother from back then to let him go to the United States
Cao Yusheng withdrew his gaze from the window and closed the window panel.
…
Under the ground, the organs in the urn city of Heishuilong City blocked Lin Shuo and the others from outside the city.
Lin Shuo doesn't know who built this city, but one thing is certain, the family is very rich and has invested heavily here.
Judging from the degree of weathering of the city gate, this city is at least five hundred years old. Lin Shuo originally thought that after so many years, the mechanism on the wall may have failed.
As a result, he threw a stone in, and the crossbow arrows from all directions immediately filled the passage space of the Urn City.
The hissing sound of the arrow piercing through the air, it sounds chilling to the bone.
Moreover, the mechanism here is designed very cleverly. When the crossbow arrow on the left is shot, it will just shoot into the wall hole on the right.
The mechanisms that have gone through more than five hundred years can still be effectively triggered, and the sensitivity is excellent.
This set of traps alone is already worth a fortune.
Lin Shuo looked at the silent Wei Xingshan beside him, and asked, "Old Wei, what do you think?"
"Hey!" Wei Xingshan smiled wryly, "How about we go back?"
Lin Shuo ignored him, but looked at Yang Tuo: "Dr. Yang, do you analyze?"
"This mechanism should be a weight-triggered mechanism, and a recyclable system is designed, which means that this kind of trap is not a one-off." Yang Tuo thought about his words, then shook his head, "Unless we can fly over, there is no way untie."
Lin Shuo thought for a while and said, "If we don't crack this mechanism, what if we just destroy it?"
"Then destroy its recycling system." Yang Tuo adjusted his glasses, "The crossbow arrows cannot be endless, as long as they cannot be recycled, they will always shoot out."
Lin Shuo nodded, and glanced at Wei Xingshan beside him: "The doctor's brain is indeed stronger than that of a soldier."
While speaking, Lin Shuo moved his body a little.
This wall, which Lin Shuo observed when he opened the door just now, is five or six meters thick. It looks like stone bricks on the outside, but he doesn't know what's inside.
If he wanted to destroy this kind of wall all at once, since it was Lin Shuo, he had to weigh it carefully.
But at present, it seems that Lin Shuo is the only one who can accomplish this.
"The doctor's mind is indeed good, but the doctor doesn't know how to use explosives."
Just listening to Wei Xingshan talking, he took out a bundle of detonators from the backpack behind him.
Lin Shuo froze for a moment, looking at the detonator in Wei Xingshan's hand, his eyes froze a little.
Seeing Lin Shuo's expression, Wei Xingshan didn't feel that there was anything wrong with it, but instead felt that he had more face, and said triumphantly, "I brought three bundles of this stuff with me when I came out this trip.
Let me tell you, this thing is awesome, you have to step back in a while.
Don't worry, I know what Lao Yang means, isn't it just that if one of the walls is blown up, the arrows on the opposite side can't be recovered.
Then the arrows on the opposite side are shooting, there will always be a time when the light will be shot, and we will be able to pass by then... "
While talking, Wei Xingshan found something wrong with the way the other three people looked at him.
"No, why are you looking at me like that? Am I wrong?" Wei Xingshan asked.
"You have explosives, why didn't you tell me earlier?" Lin Shuo felt an evil fire rising in his heart.
But he still controlled himself, because he knew that if he really made a move, Wei Xingshan would definitely break it.
Anne said helplessly: "Captain Wei, we have been groping along the wall for a long time, and we are still studying how to open the city gate and how to crack the mechanism. If you had taken out the explosives earlier, we would have blasted through the city wall and entered."
"That's right!" Wei Xingshan slapped his forehead, then pointed at Lin Shuo, "It's up to you."
"It's because of me?" Lin Shuo was annoyed, "Why?"
"With your monster here, don't you settle everything? I didn't realize that I was carrying explosives!" Wei Xingshan said confidently, "It's up to you, because you are too strong!"
Lin Shuo was taken aback by the words, and he didn't know how to refute for a moment.
Yang Tuo sighed and reminded: "Captain Wei, don't waste any more time, do it as soon as possible."
"good!"
