It can be seen that when mentioning the old events that happened in the history of Kaifeng City, Ling Xuan seemed to be immersed in the scene, and his tone was full of emotion.

However, despite the emotion in Ling Xuan's mouth, we were not satisfied with his only explanation.

Although he was scolded by Ling Xuan just now, Shen Lang has always been faceless and skinless, and after Ling Xuan's words fell, he immediately asked his question with a smile.

"No, Master, Kaifeng has been here for thousands of years, since it was originally designated as the national capital because of the geographical location, then now that Kaifeng City is still here, why do you say that this place has declined?"

While Shen Lang raised questions, he was actually ready to be scolded again, but to his surprise, after Ling Xuan heard his words, instead of scolding again, there was a trace of appreciation in his eyes.

"Yes, you don't have a lot of patience, but at least you've got the point."

Looking at Shen Lang's overwhelmed appearance, Ling Xuan patiently continued to explain like a teacher.

"In fact, if you listen carefully to what I just said, you should notice that I specifically mentioned that in the era of the canal, the history of all dynasties and generations invariably chose Kaifeng as the capital, and the focus of this sentence is not in Kaifeng, but in the canal."

"In ancient times, due to the lack of scientific and technological means of the ancients, so although everyone knew that the Yellow River was dangerous, but there was no way, people could only rely on the canal as a means of transportation, and it was precisely for this reason that the Sui Dynasty overhauled the canal, and Kaifeng was an extremely important hub in the Grand Canal."

"It is in this situation that Kaifeng, which is adjacent to the Yellow River, has become the capital of choice for many dynasties, and it can be said that it is precisely because of Kaifeng's unique geographical location that all dynasties have taken this place as the capital, and have the reputation of the ancient capital of the Eight Dynasties."

And speaking of this, Ling Xuan's tone suddenly changed, and his mouth was full of emotion that made people feel vicissitudes.

"But obviously, we are no longer in the era of the canal, as the so-called success and defeat are also Xiao He, as you can see, the current Kaifeng is indeed far from what it was before as the national capital, and the reason why Kaifeng will decline to this point, the real reason is precisely because of this geographical location!"

To my surprise, this time Ling Xuan didn't play tricks, and after seeing the puzzled expressions on our faces, he seriously explained this seemingly contradictory remark.

"Although Kaifeng seems to have a convenient waterway, it is actually very dangerous, because the Yellow River basin near this place has a small drop and slow water flow, so there is sediment and sand all the time, the riverbed continues to rise with time, and the embankment built is constantly increasing year after year."

"Although it seems that nothing happens, there will always be a day when such a cycle will be broken, and as long as this cycle is broken, it will bring a tragedy."

"Although the too old records have been lost, but only from the Southern Song Dynasty to the time of liberation, the Yellow River has reached more than 300 times in Kaifeng, the river has undergone seven major changes, and Kaifeng City has even been besieged by floods 15 times, four of which can be called a catastrophe."

Hearing Ling Xuan say these appalling numbers from his mouth, everyone's faces were filled with shock.

Fire and water are merciless.

Although we have not personally experienced such a tragic situation, these numbers invisibly remind us that this seemingly gentle Yellow River is by no means calm on the surface, but I don't know how many people were buried in it when the embankment was broken?

Seeing the shocked expression on our faces, Ling Xuan nodded at us, signaling that we had heard correctly, and then continued.

"More than 100 years ago, the north-south Jinghan Railway began to be built, according to the original plan, the railway was supposed to pass through Kaifeng, and then the future east-west Longhai Railway in Kaifeng to form a cross, but because of the existence of the Yellow River, this plan was opposed, and the fate of Kaifeng has been rewritten since then."

"After Zhang Zhidong's decision, in the end, the Jinghan Railway gave up Kaifeng in order to avoid danger, and instead changed to pass through Zhengzhou, and Kaifeng missed the opportunity to become the heart hub of China again."

Hearing this, I recovered from the shock just now and asked Ling Xuan another question.

"Even if Kaifeng does not become the heart hub of Shenzhou transportation, it should not be forgotten because of this, although the railway cannot pass through this place, but in Kaifeng City, can not make some changes?"

"Han Chuan, you mentioned another problem."

Ling Xuan shook his head, looking at his appearance, it was obvious that there was another story in this.

"As you said, although Kaifeng missed the Jinghan Railway, but now, with the increasing development of science and technology, people have indeed thought about repairing Kaifeng, and before the repair, archaeologists came here to conduct field surveys, and the final survey results show that there is actually something else under the Kaifeng City."

At the mention of this, Ling Xuan, who had always been calm, couldn't help but take a long breath, and it seemed that what he said next was even more sensational.

My prediction was indeed correct, after hearing Ling Xuan's next explanation, the expressions on everyone's expressions that had just recovered from the shock were obviously frightened again,

"The survey results show that the ruins of the Great Liang City of Wei during the Warring States Period are under the Kaifeng City, twelve to fourteen meters from the surface, and the Bianzhou City of the Sui and Tang Dynasties is also located under the current Kaifeng City, ten to twelve meters from the surface."

"In addition to the Warring States and Sui and Tang Dynasties, the old site of Bianliang City in the Northern Song Dynasty was eight to ten meters from the surface, the former site of the capital city in the Yuan Dynasty was less than seven meters from the surface, the Kaifeng Mansion in the Ming Dynasty was only five to six meters from the surface, and the Kaifeng City of the Qing Dynasty was only three to four meters from the surface!"

As Ling Xuan finished speaking, everyone was in an uproar.

Shen Lang couldn't believe what Ling Xuan said at all, and after Ling Xuan's words fell, he suddenly stood up from his seat, and asked incoherently while pointing to the ground with a complicated expression.

"What!? What the!? Master, do you mean that we are now standing on top of these former capitals? ”

Ling Xuan nodded, although the expression on his face was also a little complicated, the tone in his mouth was extremely affirmative.

"That's right, these ancient cities for more than 2,000 years are now silent one after another under the Kaifeng City where we are located, so for the sake of protecting history, Kaifeng City is still unable to carry out any construction underground, which is also a reason for its gradual decline."
