Chapter 561 Li Tai's Sailing Dream
"The earth is like a football? Then, master, what about the stars? Are they embedded in the surface of the football?"

Seeing that Master really knew the answer, Li Tai immediately became excited.

Leng Feng shook his head: "Of course not. In fact, the stars we see exist just like the sun, but they are too far away from us, so they seem to be only a little bit. The other stars are not Revolving on the sky, their real size may be countless times larger than our earth.

In fact, our earth revolves around the sun.Li Ke, go outside and get some more footballs. "

After ordering Li Ke to go outside to get a lot of footballs, Leng Feng used footballs to form a model of the solar system, and explained to the three brothers what the solar system is like and what the universe is like.

Listening to Leng Feng's explanation, the three brothers were all shocked.

In their impression, the master is omniscient, but what the master said is too
terrible!

It turns out that human beings are not the spirit of all things, but just a tiny speck of dust in the vast and boundless universe.

After talking a lot, Leng Feng sat on Li Tai's chair drinking tea, waiting for the three brothers to recover from the shock.

After a long time, Li Tai was the first to recover, and stretched out two fingers: "Master, I have two questions."

Leng Feng nodded.

"First, since we all live on a sphere, won't the one underneath fall down?"

This is a good question, and Leng Feng clapped his hands: "This is also something I plan to teach you in the future. This is the gravity brought to us by the earth under our feet. Gravity will pull anything on the surface of the sphere, just like A circular magnet is like absorbing iron sand. In the future, if you want to study aircraft, you must find a way to fight against this force."

Leng Feng's explanation was very vivid, and Li Tai's doubts were immediately resolved.

Immediately afterwards, he asked again: "Second question, Master, if you say that, we can't fly out to the sky to see it, so let's verify your statement!"

Leng Feng laughed loudly: "Actually, the way to prove this thing is very simple. Isn't there an idiom called polar opposites? The north and the south are extremely cold polar regions, and the north and south directions don't matter. When the steam engine is researched, we can build a very special one." Big steamer, and then all the way west along the coastline. Believe in Master, the boat departs from Lingnan, and it will definitely return to Suzhou and Hangzhou in the end."

"You can still do that!"

Li Tai's eyes widened. Since Master has a way to prove it, then what Master said must be correct.

Li Chengqian and Li Ke looked at each other, and didn't know what to say. Today, they seem to have obtained a secret from Master that no one knows about?

Li Tai grabbed the paper in his hand, and suddenly had an idea to prove it.

Build a big ship powered by a steam engine?Just wait until the rubber tree grows enough?
Thinking of this, Li Tai suddenly wanted to go to Lingnan to see how the rubber trees were growing.

Because Chang'an did not meet the conditions for the growth of rubber trees, the seeds of those rubber trees were sent to Feng An in Lingnan, and Feng An was specifically asked to treat them as his life.

I don't know how long it will take for those rubber trees to grow up!
Maybe he said it unknowingly, Li Tai heard the answer from his master: "It will take five or six years!"

Five or six years is not long, but in fact it is not short.

"Okay, all three of you pack up, we will leave for Hanzhong in these two days."

Speaking of cleaning up, in fact, there are not many things that need to be cleaned up. The three brothers only need to bring their own guards. All the things they need on the road will be properly arranged by those guards.

In fact, Leng Feng wanted to take his son girl out to play at first, but considering that Li Yuanchang was likely to jump over the wall in a hurry, he just sat down.

In the early morning of the next day, the imperial court issued a notice that "Duke Xiong is on behalf of the sky to patrol the inner roads of the pass".

This notice seemed particularly strange to the courtiers!
On the Guannei Road side, there were no major incidents. Even if there were, the person who went there should not be an idler like Duke Xun!There are so many talented people in the court, why did you send Duke Xing to go there?
However, the order was issued by the emperor, and the people below did not dare to say anything more.

The Dragon Tooth Army replenished the base eight gunpowder weapons in the Jinglei Division!

Originally, Zhang Zhongqing wanted to give Leng Fengji dozens of gunpowder weapons, but after the Wuli Sima who was in charge of Jinglei Division cried with his head in his arms, it could only be changed to a base number of eight.

But for the other [-]%, Zhang Zhongqing replaced them with his gasoline weapons.

Like gunpowder weapons, Zhang Zhongqing turned gasoline into incendiary bombs, explosive bombs, and incendiary arrows.

The wooden arrow shaft with a layer of wax on the inside is full of gasoline, some icing sugar, and small pieces of wood. If it is ignited and shot out, just one arrow is enough to ignite a tall building.

The well-equipped Dragon Tooth Army left Chang'an and marched mightily towards Hanzhong.

Along the road, merchants and pedestrians gave way one after another, and even some state capitals dared to open the city gates only after verifying Leng Feng's identity.

Have no idea!Although there were only more than 1000 of these people, they were well-armored and all of them looked like capable soldiers.What's more, when will an army of more than 1000 people be equipped with eight-ox crossbows?

That big killer is scary even looking at it from a distance.

Although it was the siege who asked to enter and rest, but in the eyes of the soldiers defending the city, these guys looked more like they were here to attack the city.

As for the Ba Niu Crossbow, Leng Feng was also helpless. The burning arrow made by Zhang Zhongqing was indeed powerful, but it also had disadvantages.

It is because it is not an arrow of a bow, but an eight-ox crossbow is needed to shoot it.

Before leaving, Leng Feng had to spend a lot of effort to get a eight-ox crossbow from the Military Weapons Supervision. Wu Tian had a painful look on his face. Those who didn't know really thought that Leng Feng was using the eight-ox crossbow to do bad things. go!
This time it wasn't an army war, so Leng Feng didn't concentrate on his journey, and he didn't have high demands on his subordinates.Even in order to go to see Taibai Mountain, Leng Feng and others took a long detour after passing Shouyang Mountain.

Famous mountains in the world are probably all the same. They all think they are beautiful and magnificent when they hear the rumors, but after seeing them in person, they will find nothing interesting.

Mountain climbing is a necessary activity. The mountain climbing during the day consumed all of Li Tai's physical strength, so that he fell asleep as soon as he returned to the camp.

"Hahahaha, I must go around the earth once in the future."

Listening to the sleeping Li Tai talking in his sleep, Li Chengqian and Li Ke both laughed.
