The chess on the table is Go, and the pieces and the board look very ordinary and there is nothing special about it.

The black and white chess pieces are made of plain granite.

Lu Yuan also learned Go when he was a child, and although he was not able to become a master in the end, he also had an amateur 4-dan level back then.

Over the years, although the chess skills have been abandoned due to expeditions in various places, there are still some levels.

It's even better than today's ordinary amateur 5 dan.

Seeing the chessboard pieces in this place naturally aroused his interest.

As we all know, there are two most recognized ways to describe the origin of Go in the traditional description.

One is "Yao made Go and taught his son Danzhu." Another saying is, "Shun is foolish with his son, so he makes Go to teach him!"

According to these two theories, the history of Go is only more than 4,000 years.

The earliest checkerboard-shaped object found in archaeology is a piece of pottery from the Hemudu civilization.

Even this piece of pottery is only 7,000-8,000 years old.

But this ancient city under the sea is at least 10,000 years old.

The chessboard and chess pieces in front of him obviously subverted Lu Yuan's perception of Go.

What shocked Lu Yuan even more was that the chessboard in front of him was already composed of 19 lines.

Traditionally, the study of Go has held that the Go board in the Yao Shun era consisted of 11 lines.

It was not until the Shang and Zhou dynasties that a 17-line chessboard appeared, and a 19-line chessboard did not appear until the Warring States period.

The dominance of the 19-way chessboard will not be until the period of Emperor Wu of Liang in the Southern Dynasty.

The chessboard in front of him completely subverted Lu Yuan's previous perception of Go.

Suppressing the shock in his heart, Lu Yuan shifted his attention to the chess game on the chessboard.

What is left on the board is a typical endgame, and the whole board is full of fierce battles between the two sides in the middle game.

The situation now looks chaotic, and there are six pieces of chess on the entire board that are engaged in fierce wrestling.

Lu Yuan felt dizzy when he first saw the chess game.

It took a while to understand the situation in front of me.

But because of this, his divine sense was gradually attracted to the chess game and became obsessed with it.

In a trance, Lu Yuan felt as if he had returned to the ancient battlefield......

When Lu Yuan was addicted to the chess game, the outside world had already turned upside down.

Not long after Lu Yuan entered the ancient city under the sea, the yacht he was driving was discovered by a passing fishing boat.

At first, the people on the fishing boat didn't pay much attention to it, but they just thought that it was another rich man who had nothing to do to play on the sea.

But after a whole day, the boat still didn't move.

This makes the people on the fishing boat feel strange.

After careful observation, the people on the fishing boat found that there was no one on board.

Driven by curiosity, the people on the fishing boat decided to get closer to the cruise ship to have a look.

Soon the fishing boat approached Lu Yuan's pleasure boat.

The people on the fishing boat were surprised to find that there was no one on such a large pleasure boat.

Everyone jumped on the boat to see if they could find some clues.

After some searching, the group found some items printed with Chinese characters.

Some high-end daily necessities were also found on board.

Soon some blood stains were found in the cabin.

These bloodstains were left by Lu Yuan, who was injured in a battle with the octopus monster.

After treating the wound, although some cleaning was done, there were still some blood stains left.

In such an inaccessible sea, an unmanned cruise ship appeared, and more importantly, there were blood stains on board.

It didn't look like a good thing, and several sailors naturally thought of murder first, and pirates second.

The sailors on the fishing boat, after some deliberation, still chose to call the police.

After receiving the alarm, the first to come to this area of the sea was the Saxon patrol boat.

Then the Franks, the Rice and the West also rushed to the sea area where the incident occurred.

At first, the countries did not pay attention to the incident, and only handed him over to ordinary police.

However, the police soon found out that the yacht belonged to Lu Yuan.

When the information that Lu Yuan was the owner of this yacht was uploaded.

Countries are suddenly taking this matter seriously.

Because of the joint research institute, all countries have a certain understanding of Lu Yuan.

The higher-ups all knew that Lu Yuan had been exploring and investigating the world's lost civilizations.

Lu Yuan's yacht appeared here, and everyone naturally didn't think that Lu Yuan was idle and bored to travel here.

The first thing that came to the minds of the countries was what secret Lu Yuan had discovered in this sea area.

While everyone was speculating, another investigation report appeared in front of everyone.

After studying the bloodstains left on the ship, the owner of the bloodstains was Lu Yuan.

Everyone believed that Lu Yuan must have discovered some great secret in this sea area.

According to the investigations of various countries on Lu Yuan, Lu Yuan himself is also very powerful, and to exaggerate, Lu Yuan can be regarded as a super human.

Lu Yuan, who has great strength, left a trail of blood on his ship, and he himself is missing.

In the end, various agencies judged that Lu Yuan must have encountered a powerful enemy here.

I have to say that there are still many smart people in human beings.

A middle-aged police officer, after some investigation and analysis, wrote a report like his superior.

In the report, he put forward a point of view, he believes that Lu Yuan has explored the sea after arriving in this sea area.

He even deduced that it should be an unknown sea creature that attacked Lu Yuan.

However, his report was dismissed as nonsense by his superiors.

At the same time, a young intelligence officer in the United States made a similar judgment.

And he speculated that Lu Yuan had returned to the ship after being attacked, and the bloodstains on the ship were left at this time.

He certainly wasn't speculating, and investigators found traces of a cleaned boat on board.

The young man believed that the person who cleaned the cabin was Lu Yuan.

He speculated that Lu Yuan had recuperated from his injuries and then explored underwater again, but he was not optimistic about Lu Yuan's disappearance.

While the countries were investigating the matter, a reporter from the United States sneaked into the investigation team and obtained the investigation report handed in by the young man.

Subsequently, another reporter also obtained his speculation about the cruise ship incident from the middle-aged policeman.

Soon the two reporters stabbed the incident out.

In order to attract people's attention, with exaggerated headline articles, they appeared on the top of various media.

"The world-famous explorer Lu Yuan was attacked by a sea monster in a certain sea area, and now his whereabouts are unknown......"

"The North Sea Monster haunts the explorer Lu Yuan and becomes the first victim ......"

"Be careful, the mysterious sea monster has reappeared......"
