Time went back half a year ago.

The moment the position of the prince came to light, the hearts of the Pan family and his son were empty. Years of expectations and plans were gone, and life was meaningless at this moment!

After all, the greater the hope, the greater the disappointment. Without hope, there is no light on the road of life. No matter how dark you move forward, you can only usher in darkness.

Even though you can still laugh on your face and maintain your last dignity when facing the "enemy", only you know how forced and tiring that smile is.

However, Zhao Gou obviously couldn't give up on this cheap son.

He had only two cheap sons in total. Whether it was Zhao Guan or Zhao Yuan, they all held Zhao Gou's great expectations.

Zhao Guan is in charge of the Central Plains, and Zhao Yuan opens up overseas, one inside and one outside, two cheap sons, no one can be missing!

Zhao Gou's comfort to the Pan family and his son is a map that has never been seen by the fourth pair of eyes again.

Then it is not a map, it is a new century.

Pan and Zhao Yuan and his son were stunned when they looked at the map.

"Is this the world map?"

The emperor is not lying to them, mother and son, this picture is too different from the published map.

The emperor actually said that the world is a ‘ball’!

Zhao Yuan had heard of Zhang Heng's Huntian saying that Huntian is like a chicken. The celestial body is round like a projectile, the earth is like a yellow in the chicken, living alone in the sky, the sky is big and the earth is small. There is water inside the sky, and the sky covers the ground, just like the shell wraps yellow.

But what is more accepted by the world is still "the sky is round and the place is round"!

Zhao Gou didn't have to spend more time explaining to Zhao Yuan and his son why the "world" is just a ball!

Zhao Yuan had long been instilled with the fact that the sail was seen on the sea before the hull.

"The plains here are vast and the water and soil are lush and the Han territory of the Central Plains." Zhao Gou pointed to North America and explained to the Pan family and his son.

The piece in the map that faces North America is marked with red and blue lines. The red lines indicate high mountains. Although Zhao Gou still remembers that the mountain range that runs north and south through the west coast of North America is called Rocky Mountain, he forgot what the name of the mountain range in South America is. It took too long for him to return his junior high school geography knowledge to the teacher, but he also forgot a lot.

In addition to that mountain range, there is also the Mississippi River in North America. He can also remember the name, and then the Great Lakes. The latter is marked with a dotted blue line.

The appearance of the entire North America must be very different from the real lines in reality, but Zhao Gou at least marked it.

After all, North America is very easy to draw. There are many heads in the northwest (Alaska), many tails in the southeast (Florida), and a leg at the bottom (Mexico). In addition, North America is almost a cube.

The seven continents and four oceans on the entire map are all in sight. In addition to the discovery of the Eurasian continent, the lines are very different, whether they are Hei Shuli, North and South America, or Oceania.

But this is not Zhao Gou's biggest difficulty, nor is it the most valuable thing on the map.

At least in Zhao Gou's eyes, the distribution of ocean currents that were generally marked by him were of high value, and the emergence of the New World was no less than that of the emergence of the New World. The difficulty was even more difficult than drawing a world map.

Ocean currents are very complex in themselves, and they are divided into warm currents and cold currents. They have them in coastal areas of all continents.

Not to mention that he has been away from school for so many years, even for the students in the past, I am afraid that many people can't remember everything.

What impressed Zhao Gou most was the two circles clockwise and counterclockwise in the northern and southern hemispheres. In addition to the equatorial countercurrent and west wind drifting, all the others were forgotten.

Moreover, it is the equatorial countercurrent and the clockwise counterclockwise of the northern and southern hemispheres. He himself cannot determine which end is which one!

But he was not sure, the navy could be sure.

The equatorial countercurrent is from west to east, and the west wind drift is even more obvious.

The dark tide goes from south to north, so the current circle in the northern hemisphere is naturally clockwise.

There is also an ocean current from north to south to the north to the north. If you remember correctly, it will be a cold current in Thousand Islands. If nothing unexpected happens, the cold current in Thousand Islands and the current running through both sides of the Pacific Ocean can form another closed-circuit cycle together with the Arctic Ocean.

Zhao Gou's most memorable impression of the world's ocean current distribution map is the "circles" one by one!

North, east and west, anywhere, there are closed loops of large and small sizes!

For example, the ocean currents in the Dzi Zhuhai. With the equator as the dividing line, the two currents are in opposite directions. The merchant ships of the Song people directly made their business to the Hei Shuli. This situation is naturally under the control of Zhao Gou, and the situation in the entire Tianzhuhai Sea cannot be hidden from him.

In the South Pacific, it is exactly the opposite of the North Pacific. One is clockwise, and the other is naturally counterclockwise.

The ocean currents from north to south on the east coast of Oceania, the ocean currents from south to north on the west coast of South America, and of course the ocean currents in the opposite direction on the west coast of North America will definitely be of beyond imagination for Zhao Yuan's future development of America.

Zhao Gou's expectations for him were never just Luzon Islands, or Oceania further south. When Oceania was discovered, its natural geographical location was destined to become the fat meat at the mouth of Song Dynasty.

However, if America is not guided specifically, it would be extremely difficult to discover the current "world cognition" of Zhao Song!

However, although Zhao Gou's attitude and rhetoric comforted the Pan family and his son to a certain extent, it was really difficult for Zhao Yuan and his son to feel at ease.

Because of the origin of this picture, Zhao Gou could not come up with a certain statement.

Whether it is the world or the ball, or the seven continents and four oceans, it has too much conflict with the mother and son's worldview.

There are no new discoveries on the market to confirm that the "Seven Continents and Four Oceans" are correct.

This situation lasted for half a year, and it is conceivable how intense the emotions the mother and son accumulated.

When the news came that the expedition team discovered a huge land continent in the strange waters south of Jawa Island, Zhao Yuan jumped up.

After a full half a year, he finally waited for the 'evidence'!

This gave Zhao Yuan a great encouragement!

It proves the correctness of the "Seven Continents and Four Oceans" and further proves Zhao Gou's fatherly love for him.

Although Zhao Gou did not choose him for the candidate who was concerned about the world, he also made some arrangements for him!

Zhao Gou’s explanation to them, mother and son is not false!

"The father once said that the land is vast and wealthy, and there is not even a country I want. All the people above are savages, most of whom were old people who fled east during the Shang Dynasty! It can be said to be a piece of white paper..."
