Hearing this, Wang Bo took out his geography book and mobile phone and checked them one by one without saying anything.

Very good, he has seen the issue of climate zones.

Blue Star can be divided into seven climate zones in total, from north to south: frigid zone, temperate zone, subtropical zone, tropical zone, subtropical zone, temperate zone and frigid zone.

The distribution is even and clear at a glance.

But the problem is...

The temperature change between subtropical and temperate zones is not obvious?

Sometimes the subtropical zone is also included in the temperate zone. Although it is about to reach the cold zone, the temperature change will not exceed 20 degrees.

If you were in the Mediterranean and it was around 30 degrees, the coldest here is only 10 degrees. If it is too extreme, I will give you 0 degrees, which is as high as the sky.

After all, I didn't really come to the cold zone.

Is this 0 degree temperature really going to freeze someone to death?

Wang Bo said he didn’t believe it.

After checking the information, he still pursed his lips and frowned, looking at Ren Yan with a constipated look on his face.

He felt that Teacher Ren was just playing tricks on him and bullying him for his low academic qualifications.

"Alas~" Ren Yan sighed and scratched his hair: "You guys really lack life experience."

"Once the temperature difference quickly exceeds 10 degrees, the human body is very likely to be unable to adapt, and it is not uncommon to freeze to death or die from heat."

"I remember there was news a while ago that the temperature in a certain tropical area dropped sharply by 15 degrees, from more than 40 degrees to 28.9 degrees. Many people froze to death that day, and then one after another

There are still people freezing to death."

"Only those who have long clothes at home can barely carry it."

Seeing the shocked expressions on the students' faces, Ren Yan nodded: "You heard me right, temperatures above 20 degrees will freeze to death..."

"So you still think that you, wearing short-sleeves and running from the subtropical zone to the frigid zone, can't freeze to death?"

"Even if your sailing time is doubled, without sufficient adaptation time and prepared clothes in advance, your crew will still be on the verge of death. Don't underestimate nature."

After Ren Yan finished speaking, he casually rubbed Wang Bo's head.

Wang Bo could only accept the fact that he died in despair, sighed deeply, and kept the issue of temperature firmly in mind.

Then, everyone turned their attention to Xia Yue.

Now, among the five people, only Xia Yue is left.

Although he is still wandering around Europe and is still far away from the Dragon Kingdom, there is still hope.

Seeing so many people looking at her, Xia Yue suddenly felt a little uncomfortable.

She pointed her finger and said timidly: "Teacher Ren, how about I give up?"

"No!"

Before Ren Yan could speak, the other students who were watching responded collectively.

Xia Yue was startled a little: "Now there's no one to play with, I'm the only one, what's the point?"

Xia Yue said.

"How can it be boring?!" the students collectively said.

"We have been playing for so long, and it's almost the end of the first class, but now no one has completed the goal. How frustrating it is."

“And we still don’t know what problems we will encounter in the future!”

"How could you give up halfway?!"

"But I..." Xia Yue was still a little confused: "But I always feel that I can't sail to the Dragon Kingdom."

"It's okay, there are still us!"

The students collectively clapped their chests (except girls), and confidently picked up maps and history books to start analysis.

"We have just conceived many routes, but due to time issues, we are not yet sure whether you will encounter Li Cheng's situation during your voyage."

"So, if you want to be able to sail safely to the Dragon Kingdom, there is a very direct route, and you will definitely be able to reach it!"

As he said that, with the understanding of the students, the monitor took a pencil and drew a big arc on the world map:

"Start from the English Channel, cross the North Sea to the Norwegian Sea, then sail along the Arctic Circle to the Bering Strait and enter the Pacific Ocean, and then sail along the Pacific Ocean all the way to the Dragon Kingdom!"

"Although this road is long, we can definitely reach it without any obstacles!"

The monitor said with unusual confidence.

Ren Yan on the side was shocked.

‘Made, these brats have just been researching for a long time and have come up with such a bad idea to sail halfway around the world?!’

Now he is somewhat confused about the brain circuits of these guys.

Actually, among all the plans, I resolutely chose the most difficult one.

Are you so proud?!

Xia Yue followed the monitor's explanation and took a good look at the world map.

Basically, it forms a huge arc starting from Europe and crossing the Eurasian continent along the north.

It’s not very difficult to understand, and you can see it on the map, all of which are sea areas.

But, the problem is...

"Won't we encounter the same problem as Wang Bo just now? If the temperature changes too much, people will die." Xia Yue said.

"That's because Wang Bo is stupid. And with his lesson, you can buy more cold clothes and high-calorie food."

"You have sufficient funds now and can fully support it. There is a high probability that you will not need any supplies in the middle. If you bring enough at one time, it will not be a big problem."

The classmates began to persuade him one after another.

Xia Yue nodded doubtfully.

After exchanging all his supplies for food and cold clothes, he resolutely embarked on the route to the Arctic Circle.

This time it's not just her, but the entire Class Nine.

Seeing this, Ren Yan didn't bother to dissuade them from their enthusiasm, just let it go and continued to arrange for them to play the game.

This time Xia Yue was the only one who made rapid progress.

Halfway through the second period of history class, Xia Yue finally reached the Dragon Kingdom after going through all kinds of hardships and won the final victory.

But even so, the students in Class 9 don't have much sense of accomplishment.

Without him, this voyage would have been too difficult.

Not only did we encounter pirates following us, dangerous glaciers, and mermaids singing along the way, but we also encountered a rat quarrel not long after the voyage, and lost most of our food in an instant.

After that, we experienced food spoilage, crew riots and many other force majeure events.

When they finally arrived at Dragon Kingdom, there were more than a hundred crew members on the ship, and only Xia Yue was dead.

Moreover, when she landed in the Dragon Kingdom, Xia Yue's character had also been infected with the cold.

According to Ren Yan, at that time, Xia Yue's character could survive for a few months at most after landing.

Therefore, to sum it up, they can be regarded as completely wiped out.

"Alas... we finally arrived, but this is the result."

The students in Class 9 were a little unwilling.

But Ren Yan just calmly announced the end of the game, and then said softly: "From the beginning when you choose this route."

"It's destined to be this result."
Chapter completed!
