Ying Changsheng nodded and said.

Speaking of which, the lighting in the magnificent palace in Huaxia has actually not been very good.

The reason is simple, there was no good lighting technology in ancient times.

After the construction of such a large-scale palace, the interior lighting must not rely on daylight.

Because there was no transparent glass on the doors and windows in ancient times, in such a situation, the inside of the huge house was fine on the outside, but the inside must be dim.

The light is extremely faint.

This is not talking.

Isn't that the Forbidden City, the Forbidden City?

The emperors of the Qing Dynasty spared no effort to replace the Forbidden City, which had purchased glass from the West, with glass doors and windows.

It's just to improve daylighting.

At this moment, the lighting situation in Xianyang Palace is actually extremely bad.

How bad is it?

Let's just talk about the moment, Win Changsheng is talking with Brother Zheng right now.

The result?

Brother Zheng is still lighting a candle made of whale oil, why?

Because of the lighting in the palace, it's really not good.

In order to ensure illumination, it is necessary to keep the lights on at all times.

In this way, the light can be guaranteed.

Right now, after Ying Changsheng's suggestion was put forward, Brother Zheng immediately felt that this was a good idea, but when he saw Brother Zheng, he said with excitement on his face.

"If you install glass windows in this Xianyang Palace, then I have one thing, if I want to say that there is a front, that is, my Zhangtai Palace must be ranked first!"

After the voice of the winning government fell.

Perhaps, I am worried that I will misunderstand myself and be greedy for enjoyment, Brother Zheng immediately continued to say.

"I do this, of course, not for my own enjoyment, I really feel that when I usually review the fold, stay in the house, the light is insufficient, every time I look at the fold for a while, I will feel dizzy, now, with this glass window, you can, greatly reduce the harm of this matter, I can, easily, without lighting the lamp, you can see the content of the fold clearly!"

"Father is wise!"

Hearing this, Ying Changsheng hurriedly bowed his hand to Ying Zheng, saying that what Brother Zheng said was indeed reasonable, and he nodded and said.

"Erchen also thinks that this matter should be done in this way!"

As he spoke, Ying Changsheng looked at Ying Zheng and said.

"After having these glass windows, I don't have to use it in Daqin's palace anymore, and during the day, there are so many lights lit, you can save a lot of candles!"

Hear the words.

Ying Zheng couldn't help laughing, laughed a few times, and nodded.

"Indeed it is, indeed it is!"

When Daqin's side was carrying out a big project inside the Xianyang Palace, all of them were inside the palace, replacing the glass windows.

Located in the far Western Regions.

Dawan finally sensed that something was wrong, he had already learned that Daqin's army was about to arrive in Dawan, and the moment he learned the news, King Dawan couldn't help but look a little panicked.

Well, although before, he dared to kill the people of Daqin, although before, he dared to hang the head of the envoy of Daqin under the city wall of Dawan to show his prestige.

But at the moment, when Great Qin's army really arrived.

This King Dawan finally realized that the situation was not good, and realized that what he had done before might lead to his own death and the destruction of the country.

At this moment, he couldn't help but ask the courtiers in front of him.

"Where did this Qin army arrive? How effective are they? How many of them are? ”

"Return to the King!"

For a while, in the palace, this minister hurriedly answered, only to hear him explain.

"The army of the Qin State, a month ago, destroyed the Luntai Kingdom, and now, it is not far away from our Dawan, and they are now only seven or eight days away from Yuchengcheng!"

"As for their number, there are about 10,000 people!"

"So fast?"

After hearing that the army of the Qin State was able to reach Yu Chengcheng in only seven or eight days.

For a while, King Dawan couldn't help but let out an exclamation.

Originally, he only thought that the Qin State was far away from Dawan, so it was unlikely that the army of the Qin State would reach Dawan to punish the monarch of such a small country as him.

Which Cheng thought that the Qin army actually braved the harsh environment in the Western Regions and killed all the way, and behold, they were about to reach Yucheng City in Dawan.

Inevitably, King Dawan, a little flustered.

However, just as King Dawan had a frightened expression on his face, King Yu Cheng of Dawan stood up.

King Yu Cheng is a little king of Dawan.

In fact, Dawan implemented a system of sub-feudal systems, divided into several small cities, and Yu Chengcheng was one of them.

The king surrendered to Dawan and was Dawan's courtier, and at this moment, he saw King Yu Cheng stand up and say to King Dawan.

"The king doesn't have to worry, the strength of the Qin State is not as strong as we imagined, we can deal with them calmly!"

"Oh?"

King Yu Cheng is the most capable general in the territory of Dawan Kingdom, and now, after hearing his words, King Dawan suddenly showed a surprised expression, and then asked.

"What do you mean?"

"The army of the Qin State is not very numerous, they only sent 10,000 troops, and how many troops do we, Dawan?"

"However, although the army of the Qin State is small, the Luntai State was not destroyed by them before?"

The king said with a frown.

Hearing this, King Yu Cheng sneered and said disdainfully.

"How can a country like Luntai be compared to our Dawan?"

Well, Dawan is indeed a little bigger than Luntai.

The total population of Luntai is only tens of thousands, while the population of Dawan is hundreds of thousands, and they also have a large number of good horses and a large number of cavalry.

In such a situation, Dawan is really much stronger than Luntai.

At this moment, I only heard King Yu Cheng open his mouth and say.

"In our Dawan Kingdom, the number of troops that can be mobilized is as high as 30,000!"

"Even if it's a wheel, can it be compared?"

"30,000 people, fight 10,000, people are still not the advantage in me?"

"How can Qin Jun be our opponent?"

"Yes, three to one, our Dawan man, can't we beat this group of thieves from the Qin State who came from afar?"

For a while, the ministers around them reacted instantly.

The ministers may not know anything about military affairs, but they are all very smart, and of course they all know arithmetic.

In their opinion, 30,000 Dawan troops, against 10,000 Qin troops, are more than enough.

However, even so, King Dawan frowned a little, and he muttered.

"Having said that, it's just that I have so many cities in Dawan, right now, distributed and defensive, it is definitely impossible for the army to be concentrated in one place, and it is very likely that the army of the Qin State will be broken by each one......"

"This ......"

Hearing this, for a while, everyone's faces in the palace changed.
