Fu Yang's mouth opened wide, and he was able to stuff an egg: "I...... Damn! I don't know, I don't know, I'm shocked when I see it. I was still wondering that there were no big rivers in Shanghai that really flowed through the city. The closest river to this sluice, and the largest river in the city, is the Suzhou Creek. With such a small amount of water, less than two meters deep, how could such a huge sluice gate be built? Now I know that it is simply shocking. ”

Vico also nodded blankly, his eyes flashing with intense shock.

Even she, the ghost king, was shocked by the hydrology and geography of the Shanghai region, why on earth?

The main problem is still on the Suzhou Creek......

Suzhou Creek, it starts from Beixinjing, flows through Putuo District, Jing'an District, Hongkou District, Huangpu District of Shanghai, and ends at the mouth of Waibaidu Bridge. Finally, it joins the mighty Huangpu River at the Waibaidu Bridge.

Suzhou Creek is a small river.

The width is only about 20 meters, and the average flow rate is only 10 cubic meters per second, which is close to zero in the dry season. At low water levels, the water depth is about 2 meters.

This seems to be a thing that most citizens in East China are familiar with.

However, in the history of China, this is not the case!

In the past, Suzhou Creek was a huge and incomparably long river, and the truth made people feel terrifying.

Suzhou Creek was called Wusong River in ancient times; When it was a little older, it was also called Matsue.

According to a number of official historical books, the average width of the Songjiang River was more than 10 kilometers for a long time in history!!

The river is wide, the momentum is surging, and there are poems and clouds: the water of Wusong is shocking, and the waves are vast and thundering!

Even until the end of the Northern Song Dynasty, the section of the Songjiang River in the Qingpu area of Shanghai City today was still "nine miles wide", and the widest part of the estuary into the sea was trumpet-shaped, 20 miles wide. Therefore, there is a saying that "Wusong Gujiang, so the road is deep and wide, and it can be rivaled by Qianpu".

From the end of the Northern Song Dynasty to the present, there is not a thousand years, about 900 years.

In just a few hundred years, a huge long river, from nearly ten miles wide, has rapidly shrunk to the current 20 meters?

This kind of frightening contrast and shrinkage speed may not be enough to describe it as "unbelievable"!

By the Yuan Dynasty, the Wusong River had shrunk to seven or eight miles. Moreover, the silt accumulation in the estuary often occurs the phenomenon of seawater backflow. In order to avoid this situation, the imperial court at that time let Ren Renfa go to Shanghai to control the waterway, and finally built this huge barrage gate.

Through the two-way gate, the waterway of the wide Wusong River is kept unblocked.

This information is not even the information of the supernatural world, but the records of ordinary people's official history!

These alone already make people feel chills and creeps on the soles of their feet.

Fu Yang's eyes were glazed, and he muttered to himself: "In other words, almost in the Qin and Han dynasties, there are at least eighty percent of the urban area of Shanghai today, and they are still sinking under deep water?" ”

Vico nodded: "I'm afraid that's right!" Even the third largest island in China, Chongming Island. It also surfaced during the Tang Dynasty and then formed. It's too short, it's unusually short. ”

That's right!

Shanghai ......

This is truly a city of mysteries!

What amazing secrets are hidden beneath the surface of the bustling modern metropolis?!

In one or two thousand years, it has completed the process that normally takes one or two million years. From a geogeological point of view, this city would not have existed at all......

"It's amazing! I was scared. ”

Fu Yang touched his chest.

He vaguely felt that there should be a big secret hidden in this. And this secret, just revealing the tip of the iceberg may make people lose all three views, which is certain subversive.

And intuitively, Fu Yang felt that this magical Yuan Dynasty sluice ruins were part of this shocking secret!

The couple sighed for a while before their minds stabilized and their emotions calmed down.

Fu Yang chuckled: "I didn't expect that the two of us can also be said to be the strong overlords of the spirit world." was actually shocked by the official history of ordinary people. ”

Wei Ke was a little noncommittal: "Non-spiritual people in the extraterrestrial world, if they know this, I'm afraid they will be excited, right?" It's a pity that in this era, everyone is trying to live and make money. They are all concerned about the economy, about buying a house and a car. How many ordinary people would care about such unpopular knowledge and information? ”

She does have a point.

I'm afraid that they are the only supernatural powerhouses who don't have any worries about food, clothing, housing and transportation. Or is it the elite among ordinary people who have the heart to explore these secrets hidden under the seemingly ordinary world, right?

"Alright, let's not sigh. This glass corridor that ordinary tourists can visit should not have anything that Wang Jian is interested in, so go to the core of the sluice gate to have a look. ”

Fu Yang took Vico's hand and pointed to the last position during the entire visit.

That's also a platform, nothing more than the lowest point in the entire sluice ruins!

There is a stretch of the sluice in front of you, just enough to see the magnificent gate and flood outlet of the sluice from close distance. Like a door to the other world, it is very mysterious and vicissitudes.

Fu Yang walked over and stared at the ruins of the spectacular sluice gate.

Hundreds of years have passed, and after some repairs, it is still shocking. It seems that you can hear the waves and roar in your ears!

"This gate, just after the repair, is nearly ten meters high at the bottom of the broken gate. I can't believe how magnificent the complete gate was back then. ”

He sighed.

But think about it.

At that time, Suzhou Creek was not only 20 meters wide as it is now, it was a 10-mile wide river even after local blockage!

What kind of skill would it take to build a sluice gate at such an inlet? How powerful paranormal spells do you need to work with?

Vico walked over and was just about to speak: "Husband, this ......"

Airplanes!!!

Sudden mutation!

The walnut-sized black stone in Fu Yang's pocket suddenly began to tremble violently and emitted a ghostly light. Automatically flew out and levitated in front of him.

Fortunately, although the Yuan Dynasty Sluice Ruins Museum is of great significance, it is a very, very unpopular place in society, and there are almost no people on weekdays. Otherwise, ordinary people would probably be shocked when they saw Fu Yang's scene.

At the moment when the small black stone shone brightly, the dilapidated and repaired ancient sluice gate in front of him burst into a burst of bright light!

Of course, it only flickered for less than a second, and then disappeared.
