Li Shimin

Li Xuan ignored these little bastards, and continued: "Although you are standing on the earth and looking towards the sky, you can see that the sun is the same size as the moon, that is because the sun is very far away from the earth.

The moon is very close to the earth, relative to the sun! "

"And the reason why we follow the coastline and go north to east is because the earth we are on is revolving around the sun.

At the same time, the earth is also rotating by itself, so the sun rises in the east and sets in the west.

And I'm still going east, the sun will naturally rise earlier and set faster..."

"The earth is divided into northern and southern hemispheres. My Tang Dynasty is in the middle of the southern hemisphere. The farther north you go, the colder it gets. It can be covered with ice all year round, or it can be day all day without night..."

Following Li Xuan's words, Cheng Chusi, Yuchi Baolin and the others did not realize that they were already sitting on the ground slowly, with their eyes wide open, looking at Li Xuan in a dazed manner.

What Li Xuan said was completely contrary to the knowledge they had read in books since they were young!
However, according to what Li Xuan said, the more they thought about it, the more reasonable they felt.

It seems that what Li Xuan said is correct.

However, the books they read are all the words of the sages!

Along the way, Li Baoding, Wang Xuance, Li Chengqian and others seemed to have found a new purpose in life. They surrounded Li Xuan all day long and listened to Li Xuan's explanation of astronomical knowledge.

At the same time, while asking, it was recorded in some books.

Fortunately, when they came, they knew that the journey was long and it would take more than a year.

I also brought two large boxes of books, pens and ink.

So, on the next road, the few people were no longer boring.

As for Li Xuan, when he was bored, he could tell these little bastards some knowledge that he had never told the people of Tang Dynasty, which was also a kind of boredom, a kind of vent.

in this way.

Two months later, they finally left the island of Wa Kingdom and entered a narrow belt of islands.

"Master, why are these islands so small? Moreover, they are so densely arranged?"

Sitting on the bow of the boat, Wang Xuance asked curiously.

"how could I know!"

Li Xuan said angrily.

Hearing this, Wang Xuance, Li Baoding and the others were not afraid, and all laughed.

For two consecutive months, they were sailing in the sea, and they could only rely on Li Xuan to tell them about astronomy and the stars in the sky to relieve their boredom.

At the same time, in order to prevent the crew and soldiers from going crazy from boredom, Li Xuan asked Cheng Chusi, Wang Xuance and others to go to the ships behind him and tell stories to the crew and soldiers.

Teach pinyin letters, numbers and arithmetic, enlightenment, astronomy...

Anyway, along the way, the crew enlightenment class began.

With learning objectives, those soldiers and crew members are full of motivation and no longer feel boring.

"Ok?"

Suddenly, within a few days of walking, Li Baoding, Cheng Chusi and others hurried to find Li Xuan again, their faces full of panic.

"What happened?"

Seeing this, Li Xuan couldn't help being surprised.

"Master, there is a big island in front that is breathing fire!"

Cheng Chusi shouted.

"Fire-breathing?"

Li Xuan was startled, got up quickly, picked up clairvoyance, and looked into the distance.

Sure enough, not far away, a small island sprayed fiery red magma, which fell into the nearby sea, emitting a large amount of white smoke.

After a while, the area was filled with smoke.

"It's okay, pass on the order, this is just a volcanic eruption, don't make a fuss!"

Li Xuan said.

"Yes!"

Xue Rengui hurriedly passed down the order, and as the order was passed down, the soldiers and crew members on the large ships behind gradually returned to calm.

Along the way, Li Xuan became the backbone of these soldiers and crew. As long as Li Xuan said that there was nothing serious, these people could calm down quickly.

However, all the soldiers and crew members were still bewildered looking at the fire-breathing island in the distance, full of astonishment.

Not only have they never seen a fire-breathing island, they haven't even heard of it.

"Master, what is a volcanic eruption? Could it be that these islands are all volcanoes? But none of these islands are on fire!"

Cheng Chusi asked curiously.

"It's because the inside of these islands is surrounded by a puddle of fire water. You can think of it as a bun. These islands are the skin of the bun, and the inside is a pile of fire water stuffing. When there is too much fire water inside, or there is A force is squeezed inside, and those fiery waters are sprayed out..."

Li Xuan explained patiently.

"Master, is there fire water in these islands?"

Hearing this, Li Chengqian, Cheng Chusi and the others couldn't help but widen their eyes with astonishment.

"Without fire water, how did the fire water in these islands come out?"

Li Xuan said helplessly.

"hey-hey……"

Cheng Chusi, who was asking the question, also knew that he had asked a particularly stupid question, so he smiled.

Then, all the people raised their clairvoyant eyes again, and looked at it stupidly.

On the side, Xue Rengui silently wrote down what Li Xuan said, then walked down quickly, spreading Li Xuan's explanation to the entire fleet again.

The soldiers and crew of more than 2000 also suddenly realized that they were no longer afraid.

His Royal Highness King Jin is really powerful, even if there is fire and water in the belly of the volcano, he knows it!
However, in the next few days, the panic of Cheng Chusi, Li Chengqian and others did not stop.

Soon, even if they were sitting on the boat, they could feel the sea water stirring.

A wide wave hit the ship, scaring all the crew and soldiers, and their faces were pale.

They could even see that the islands on the left side of their fleet were shaking.

The rocks on the island rolled down into the sea from time to time, and several islands were also erupting red fire...

Great omen!

"Master, the Sea God here is angry, is it because they don't welcome me?"

The bastard Cheng Chusi started to feel muddled again, and came to Li Xuan's side with a terrified expression.

And on the entire fleet, all the crew and soldiers were also terrified.

Even, many crew members knelt on the ground and kowtowed to the sea to beg for mercy!

Seeing this, Li Xuan took a long breath and said:

"Where is the Sea God? This is an earthquake. Could it be that you haven't read the historical records?"

Seeing Li Xuan's expression, Cheng Chusi, Li Chongyi and others also breathed a sigh of relief.

However, he was soon full of doubts again.

"What is an earthquake?"

"That's Earth Dragon turning over!"

Li Xuan explained.

"It turned out that the earth dragon turned over?"

Now, Cheng Chusi and Li Chongyi were all surprised, and quickly raised their clairvoyance again, looking towards the small islands in the distance.

They have also seen records in the books. In the former Sui Dynasty, it seems that six times the earth dragon turned over, the earth pulse trembled, the earth cracked and collapsed, and many cattle, sheep, people, and houses fell into the earth seam and were swallowed by the earth dragon!

Unexpectedly, in their lifetime, they could still watch the Earth Dragon turn over so closely.

And behind several people, Xue Rengui silently said these words again, and came to the stern.

He raised the huge iron horn at the stern and began to explain to the fleet behind him.

This time, the impact of the earthquake was too great. Xue Rengui explained for a long time before the crew and soldiers calmed down.

However, all of them were still nervous and looked around cautiously.
