Time goes back to half a year ago.

At the moment when the crown prince's position was revealed, the hearts of Pan's mother and son were empty. Years of anticipation and planning have come to naught, and life has lost its meaning at this moment!

After all, the greater the hope, the greater the disappointment. There is no hope, there is no light on the road of life, and no matter how you move forward in the dark, you can only usher in darkness.

Even though he can still smile on his face and maintain his last dignity in the face of the 'enemy', only he knows how reluctant and tired that smile is.

However, it is obviously impossible for Zhao Gou to give up this cheap son.

He has two cheap sons, whether it is Zhao Xuan or Zhao Jin, they all have a lot of expectations from Zhao Gou.

Zhao Xuan sits in Middle-earth, Zhao Ying opens up overseas, one inside and one outside, two cheap sons, neither of which can be missing!

Zhao Gou's appeasement of Pan's mother and son is a map that has never been seen by the fourth pair of eyes again.

Where is a map, it is a new century.

Pan and Zhao Ming's mother and son looked at the map, and everyone was stunned.

"This is the world map?"

The emperor is not lying to their mother and son, this map is too different from the map that has been released.

The emperor even said that the world is a 'ball'!

Zhao Ying has heard of Zhang Heng's Hun Tian said, Hun Tian is like a chicken. The celestial bodies are round like projectiles, the earth is like a chicken in the middle yellow, and it lives alone in the sky, the sky is big and the earth is small. There is water in the sky, and the sky envelops the earth, and the shell is yellow.

But now what is more accepted by the world is still 'the sky is round'!

Zhao Gou doesn't have to bother to explain how 'the world' is a ball for Zhao Ming's mother and son!

The fact that the sail is seen on the sea and then the hull of the ship has long been instilled in Zhao Ming.

"The plains here are vast, and the water and soil are as rich as the Han soil of the Central Plains." Zhao Gou pointed to North America and explained to Pan's mother and son.

The part of the map that deals with North America is also marked by red and blue lines. The red bar marked the high mountains, although Zhao Gou still remembered that the mountain range that ran north and south through the west coast of North America was called Rocky Mountain, but he forgot the name of the mountain range in South America. Time has passed too long, and although his junior high school geography knowledge has not been completely returned to the teacher, he has forgotten a lot.

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

There must be a big difference between the appearance of the whole of North America and the real lines in reality, but it should be marked, and Zhao Gou has marked it anyway.

After all, North America is pretty easy to draw. North America has more than one head in the northwest (Alaska), multiple tails in the southeast (Florida), and one leg (Mexico) in the bottom.

The seven continents and four oceans on the whole map are in sight one by one, in addition to the Eurasian continent that has been discovered, whether it is Heishuli, or North and South America, or Oceania, the lines are very different.

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 he roughly marked was not inferior to the birth of the New World in a high value. And the difficulty is even greater than drawing a map of the world.

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

Not to mention that he has been away from school for so many years, even if he is a student of the right age, I am afraid that many people will not be able to remember all of them.

What impressed Zhao Gou the most was the clockwise and counterclockwise circles of the northern and southern hemispheres. Add to that the equatorial countercurrent and westerly drifting, and the rest is completely forgotten.

And it's the equatorial countercurrent and the clockwise counter-clockwise of the northern and southern hemispheres, and he himself can't be sure which is which!

But he can't be sure, the sailor can be sure.

The equatorial countercurrent is from west to east, and westerly drifting is even more obvious.

The Kuroshio Tide runs from south to north, so the current circle in the Northern Hemisphere is naturally clockwise.

There is also a north-to-south current to the north of Ezo, and if memory serves, it's the Kuril Current. In this way, if nothing else, the Kuril Cold Current, together with the current that runs through both sides of the Pacific Ocean, can form a closed circuit cycle in the Arctic Ocean.

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

North, south, east and west, any place, is a closed loop of all sizes!

It's like the ocean currents in Tianhaihai. With the equator as the dividing line, the two ocean currents are in opposite directions, and the merchant ships of the Song people have directly done their business in Heishu Li, this situation is naturally in Zhao Gou's grasp, and the situation of the entire Tianzhu Sea cannot be hidden from him.

The South Pacific, on the other hand, is the opposite of the North Pacific, one is clockwise and the other is counterclockwise.

The ocean currents on the east coast of Oceania from north to south, as well as 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, are absolutely incredibly helpful to Zhao Jin's future development of the Americas.

Zhao Gou's expectation for him has never been just a Luzon Islands, or Oceania further south, when Oceania was discovered, its natural geographical location was already destined to become the fat of the Great Song Dynasty's mouth.

However, in the Americas, if there is no special guidance, it is absolutely difficult to discover Zhao Song's current 'world cognition'!

However, although Zhao Gou's attitude and rhetoric appeased Pan's mother and son to a certain extent, it was really difficult for Zhao Ming's mother and son to settle down in their hearts.

Because of the origin of this picture, Zhao Gou couldn't come up with a definite statement at all.

Whether the world is a ball, or the seven continents and four oceans, there is too much conflict with the worldview of the mother and son.

And 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 you can imagine how hot the emotions accumulated in the hearts of the mother and son were.

When the news came that the expedition had discovered a huge continent in the unfamiliar waters south of Jawa Island, Zhao Ying jumped up.

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

This gave Zhao Ying great encouragement!

It proves the correctness of 'Seven Continents and Four Oceans', and it also proves Zhao Gou's fatherly love for him.

In terms of the candidate who is related to the world, although Zhao Gou did not choose him, he also made some arrangements for him!

Zhao Gou's confession to their mother and son is not false!

"My father once said that there is a lot of land and resources here, and there is no country that I want. The people on it are all savages, and most of them are old people who fled east during the Yin Shang period! It's a blank slate......"

Zhao Ming's little face was full of excitement, the white paper was easy to paint, although he lost the throne of the Son of Heaven, it was not a lost harvest.
