Chapter 449

In the face of this scholar's query, Zhang Yuan did not rush to turn out another paper below, which described the climate and environment on the back of the planet from the aspect of ocean current.

On the blackboard, he drew a picture of the ocean current of the planet with chalk: "if you stand in the atmosphere above the north pole and look down at the whole planet, you can find that the ocean current of the whole planet rotates counter clockwise. As you should know, the warm current of our Boulder City flows from the west to the East. That is, from warm places to cold places. "

"Affected by this warm current, the temperature here is warmer than other areas."

Due to the uneven heating of the planet, the energy will spontaneously transfer from the hot region to the cold region, which is the law of thermodynamics.

The planet is tidal locked by the star. The rotation period is equal to the revolution period, not without rotation. The geostrophic deflection force produced by such a weak rotation causes the general trend of ocean current and air current to be anticlockwise.

"What does that lead to?"

Zhang Yuan drew a circle on the blackboard.

"At the other end of the planet, the current flows from east to west. That is, from the cold zone to the warm zone. "

"If the cold current meets the land, it will greatly reduce the temperature of this land."

"Therefore, in theory, the climate on the back of the planet will be colder than that on this side. The temperature in the same longitude, latitude and light zone is expected to be about 10 degrees lower than that on this side, that is, the original 40 degrees Celsius will become 30 degrees Celsius."

"If we find continents in the light belt?"

"There is light, there is a continent, the climate is suitable, it will become a new paradise for mankind!"

"As long as it exists and we can Find it

The ambitious third exploration has begun again.

This time, though justified, many people were frightened. Some people once again began to ridicule Zhang Yuan's wishful thinking. Even many sailors in the family showed hesitation and fear. They were reluctant to participate in such activities.

Explore the world!

A feat never seen in the world!

The global exploration of this world is far more difficult than that of the earth. Because the earth has a large continent, there are a lot of land supply points, but the world does not. The distribution of islands in the whole world is equivalent to only one Southeast Asian archipelago. There are no Eurasian continent, South America, North America, Australia and Antarctica!

Long time away from the land, not to mention the difficulty of material supply, after a long time, everyone will have a serious sense of panic.

Zhang Yuan also knows that this may be the last exploration in his life. He is over 40 years old and his body is on the decline.

This may also be the last chance for the whole world.

He didn't force the sailors in the family who didn't want to join the expedition. The whole city of boulder is full of young people who want to get rich and famous.

However, no one knows whether this expedition is a long march to victory or a road to death.

"If we fail this time, there will be no place to explore. I'll be honest and support my family. Ha ha!" Zhang Yuan turned his head and said with a smile to his sister Anna.

Yes, if we fail, the world can only be like this.

There is no way for man to fight against the whole world. It's also good to calm down and develop some science and productivity.

Of course, in the current environment, no matter how it develops, Zhang Yuan thinks that it is impossible to break through the upper bound, it will only lead to chronic death But it's better than no development.

"Goodbye to uncle!"

Sister Anna is already a lady and mother of three. "You will be great navigators in the future."

Although she still can't understand her brother's choice, she can only support it in the end.

"Goodbye!" All the relatives and friends were seeing off on the shore.

Zhang Yuan embarked on the new ship "victory" -- with the innovation of technology, a faster steam powered schooner.

In the whole fleet, there are eight similar large ships. Zhang Yuan once again lost all the money he had earned over the years, and started his third expedition among people's comments, blessings, worship, ridicule and expectations.

A historian wrote in his own book: "count Hoffman, even if he did not discover any new continent, even if his third voyage still failed, it is enough to be remembered by history..."

"World, we need a continent, a continent full of light!"

"Let's find it. In our world, many suffering people are still hungry. They are homeless and have no clothes to wear. Let's find it..."

Zhang Yuan took a deep breath and ordered: "Yang Fan, set sail!"

The whole global exploration will go around the other side of the planet through the Arctic route. Five ships carrying 3000 people, if successful, it will take 300 days, if not, it may take 400 or even 500 days.It must have been a hard journey.

A young sailor pulled the rope with both hands, raised his sails, and looked at the little lights of Stonehenge. Suddenly, he had a feeling of not giving up.

He asked the chief officer around him, "rock, if we do find a new continent on the back of the planet, what will happen? Will we get rich? "

"Smelly boy, I've been here so early, whimsical!" The chief officer grinned and said, "even the count is not sure. But Do you know what a new continent means to us? "

"What?"

He opened his hands, as if embracing the future: "we will become the heroes of Stonehenge! We will be remembered by history! Our name, a thousand years later, can still be mentioned by human beings. "

"Whether it's wealth or honor, we can choose. If you want, you can even get a piece of fiefdom in the new world and become the owner of the Manor! Of course, if we can survive and see the sun in the new world If there is a sun

"Sun, how beautiful. I don't know. Have you ever seen the sun in the distance? "

"What if there is no new world?" Asked the young sailor.

"No new world..." He frowned and sighed: "actually, it's nothing. It's like a long voyage The count will certainly pay you, not a penny less. "

"But there is no new world..."

He turned his head and looked at a bright room on the upper deck. I really can't imagine that there will be other people in the world who are willing to explore this dark and huge world. "

"How I wish there was a new continent..."

Everyone lost interest in talking when they thought of their long life at sea in the future.

Everyone with a trace of confusion, a trace of yearning, and A little bit worried about the future.

"Victory" issued a whine, a little bit heavy, left the city. Everyone doesn't know what their future will be like. The priest on the ship started a very traditional prayer ceremony.

"May we not regret today's choice."
