Ji Menghan jumped up suddenly.

If you don't give oxygen to the light, then you must get a cover for it.

The traditional lampshade is definitely not good, that thing is leaking.

So what's the best material?

Glass, of course!

Gaojia Village already has a glazed factory, which produces huge glazed windows for everyone, and even has glazed cups, glazed bottles and so on......

Ji Menghan ran into the glass store and bought a round but narrow-mouthed glass bottle.

The next problem is that you can't let the bottle have air in it.

Ji Menghan looked at the bottle and fell into deep thought.

How do you get the air out of a bottle?

This is not a simple question.

Ji Menghan thought about this problem, but he was still puzzled, and as time passed, his research came to a standstill......

On this day, Ji Menghan was walking on the edge of the field, and suddenly heard a rumbling sound, and turned his head to see that it was the steam pump from Gaojia Village, which was pumping water from the field and draining them.

Ji Menghan's heart suddenly woke up: "Huh? What if I fill this glass bottle with water and then pump it out? You won't be able to pump it out with a small amount of force, but if you pump it with a powerful machine like a water pump, you might be able to pump the water out. The air in the bottle has long been squeezed out by the water, and if the water is pumped out, there will be no air."

Ideas are simple, but they are hard to implement.

The air tightness of the pump's pumping pipe is not very good, and the air will get into the bottle when the water is pumped out, and he also has to solve the problem of sealing the bottle immediately so that the air does not leak in while pumping the water......

In short, there are a lot of problems as big as mountains.

However, Ji Menghan still rushed over without hesitation.

Is there any reason why the son of a lampsmith cannot make a good lamp? ——

The first small section of the West Extension Railway, the railroad tracks from Xi'an to Sanyuan County, was finally fully completed.

This section of track is more than 60 miles long and costs a lot of money.

And today, the time has finally come to test run for the first time.

Zhu Cunji, the son of King Qin, stood on the platform of Xi'an North Railway Station with his own princess, side concubines, concubines, and a large group of guards.

With him, there were also Wu Fu, Shi Kefa, Xi'an Prefect, etc., a large group of court officials.

Of course, there are also some stewards sent by the imperial relatives who invested with Zhu Cunji and invested in the railroad tracks, and these shareholders have also been looking forward to this railway for a long time.

The sooner it opens, they will be able to make money sooner.

Zhu Cunji stood in front of the "train" with a smug look on his face: "Have you seen it? This train is the son of this world, hahaha, this son spent 50,000 taels of silver to customize, named the storage number, hahahaha."

Wu Fu couldn't help but mutter, "The name is really not level."

"Hey, this son hears me." Zhu Cunji pointed to Wu Fu's face and said, "Stinky civil official, don't be embarrassed, this son kindly invites you to come to see the opening ceremony, don't be there to compare Bi Lailai."

Wu Fu closed his mouth.

"Anyway, today, we're going to take this car to Sanyuan County." Zhu Cunji had an arrogant expression: "Who agrees, who opposes?"

Shi Kefa jumped out suddenly: "The lower officials are against it! In the ancestral system of this dynasty, the vassal king is not allowed to leave the fiefdom, His Royal Highness the prince, you can't go to Sanyuan County, you will be killed if you go."

Zhu Cunji: "Sanyuan County is so close! This son is gone, and he will come back immediately."

Shi Kefa shook his head: "No, no."

Zhu Cunji: "......"

He looked around, and a group of civil officials stared at him.

He invited these civil officials here to watch the ceremony this time, in fact, he wanted to persuade them here to let him leave Xi'an and go to Sanyuan County. If you don't persuade you to go directly, you can't hide such a big thing as the train, and you will definitely be told afterwards.

Persuasion is the only way!

Zhu Cunji spread his hands: "This prince knows that the vassal king is not allowed to leave the seal

The land is just to prevent the vassal king from rebelling. This son is here, and he said to Tianzun, 'If this son of the world has the heart of rebellion, Tianzun will put a bridge down and smash this son to death, how about this?' "」

Crowd: "......"

This oath is also small and fresh enough.

Seeing that the civil officials were still unmoved, Zhu Cunji sighed and began to play tricks: "Tianzun help, please show a spirit, say a word to these civil officials, let me go, let me go, I want to try my own train myself."

Tianzun is a ghost!

I don't have time to play this with him.

At this moment, Wang Tang came out of the crowd and said, "Your Royal Highness, can the bridge given by the Heavenly Venerable be able to hold up the train crossing the bridge, it has not been tested yet, are you sure you want to sit on the train?"

As soon as these words came out, Zhu Cunji's face instantly turned white.

"This ...... How can there be an immortal thing given by Tianzun...... Can't hold on...... The Doctrine of All Things?"

Wang Tang smiled: "Tianzun plays the world, and the immortals given are not all reliable, and the bus sun cars in our Gaojia Village are all divine cars given by Tianzun, and occasionally one will turn over in the ditch."

As soon as these words came out, Zhu Cunji's face turned even whiter: "Huh? That...... Piece...... What's this...... cough cough cough ...... This prince thinks about it carefully, the ancestral system cannot be violated, it cannot be violated, the vassal king must not leave the fiefdom, this prince should practice it well, and it should not be violated, cough ...... This son is gone."

"Cut! Instigation." Wu Fu scolded with a smile and stepped onto the train.

Shi Kefa also followed, and a large group of officials rushed up.

The stewards sent by the shareholders also followed the car.

In the end, only Zhu Cunji and his princesses, side concubines, and guards were left standing at Xi'an North Railway Station like fools.

Then, the memory number made a "woo" sound, and it headed north, and drove out wildly.

Zhu Cunji shouted, "Quick, ride a fast horse, go to the Wei River and see if it can cross the bridge."

The palace guards hurriedly beat their horses and galloped after the train.

The speed of high-quality war horses is not inferior to the trains of this era, and the distance of twenty miles is not enough to make war horses tired. Soon, the palace guards quickly overtook the train and rushed to the Wei River.

I saw that the big train came to the Weihe Bridge in a wild manner, and the dignitaries on the car were still a little nervous, and every window stretched out their heads and looked at the fairy bridge nervously.

However, what worried them didn't happen.

The big train smoothly rushed onto the bridge deck, easily rushed from the south bridge head to the north bridge head, and then drove away in the direction of Mihara County......

The first section of the West Extension Railway was officially opened to traffic!

After Zhu Cunji got the news, he couldn't help but be ecstatic: "Hahahaha, you can start selling tickets, selling tickets." Start advertising right away,

Tell everyone in Xi'an that the railway from Xi'an to Sanyuan County will start selling tickets tomorrow. A 100-cent ticket for a low-class car. Intermediate carriage ticket 500 wen. A tael of silver for a premium car. The top luxury car, five taels of silver. This son is making a lot of money, and I'm going to make a lot of money, hahahahaha."
