Chapter 409 New invention

The Air Force successfully launched a surprise attack but could not occupy it.

The next siege of the city and territory also requires the Ning King's troops to execute.

Uszang's army was already suffering. After this battle, there were heavy casualties. King Lianchanhua also died in the melee. Those who survived by chance either beg for surrender or fled in scattered places and had no resistance.

King Ning's troops easily penetrated deep into the hinterland of the plateau. Since then, Uszang has completely completely built the Ming Dynasty, rather than a territorial place that is not worthy of its name.

Yu Qian, the Academy of Sciences and others have returned to the capital and returned the imperial edict.

Zhu Qizhen was overjoyed and immediately named Mei Chun a third-rank commander of the Yulin Guard.

These days, he has considered it clearly, merged the Yulin Left Guard, Yulin Right Guard and Yulin Forewar into the Yulin Camp, and transformed the Kongming Lantern Institute of the Academy of Sciences into the Aerodynamic Research Institute and returned to the Yulin Camp.

From then on, the first air force of the Ming Dynasty was established.

Belin and others also rewarded each of them on their merits. All the researchers who went on the battle each received a flying fish suit.

"Your Majesty, why are you so happy?"

When Queen Qian saw Zhu Qizhen grinning and laughing non-stop, she knew that there must be something happy.

"Ha ha ha ha……"

Zhu Qizhen smiled even happier, and then said, "The little Kongming lantern is worth thousands of troops!"

Queen Qian was a little confused and asked, "What... Kongming Lantern?"

"The queen doesn't know that the Academy of Sciences has made unparalleled achievements this time, which is really a blessing for the Ming Dynasty!"

Queen Qian still didn't understand, but did not ask any further, but ordered: "Zheng'er, go and bring the ginseng soup."

"Yes, Queen!"

Wan Zhen'er carefully brought a bowl of ginseng soup and said respectfully: "Your Majesty, this is the ginseng soup cooked by the Empress himself."

Zhu Qizhen took it, looked at Wan Zhen'er, and seemed to think of something, and said, "Your two younger brothers..."

Plop!

Before he finished speaking, Wan Zhen'er had already knelt down on the ground and leaned over and said, "I beg the emperor to forgive me!"

"Don't worry, they both... are actually nothing, they have found out."

Wan Zhen'er's two younger brothers bought some saltpeter sulfur in private. Although these things are regulated, they are not strictly controlled by the public, and only bulk transactions are prohibited.

For example, there is sulfur in medicine shops, as for saltpeter, there are many stone factories.

The Jinyiwei checked the whole story and found that the two brothers of the Wan family actually had no special channels. They just heard from their sister that the prince needed this thing, so they tried every means to get it.

As for what His Royal Highness the Crown Prince used for, they were completely unaware of it.

"Thank you for your kindness, thank you for your kindness..."

Wan Zhen'er was both surprised and happy, and couldn't help but wipe her tears.

"Why are you crying? I just told you that it's okay, get up!"

Zhu Qizhen waved his hand, and Wan Zhen'er slowly stood up.

"Tell me, how are these queens in good health?"

Wan Zhen'er wiped away her tears and said, "Back to the emperor, the Empress's body has recovered very smoothly. However, the decoctions from the Imperial Hospital should continue to take for a period of time to prevent the recurrence of old diseases."

Zhu Qizhen nodded, looked at Queen Qian again, and asked, "What do the queen thinks?"

Queen Qian smiled and said, "I also feel very relaxed. I had a menstrual period yesterday, but I no longer feel any abdominal pain."

"Is that so good!"

Zhu Qizhen smiled again on his face and said, "The queen should rest early!"

"I... I'm not as good as..."

Queen Qian hesitated for a moment, then said, "Let Zhen'er serve the emperor and go to bed."

When Wan Zhen'er heard this, her face blushed to the base of her neck, and she lowered her head and didn't know what to do.

Zhu Qizhen smiled and shook his head, saying, "I am a little tired today, so I'm going to bed first."

Speaking of which, Wan Zhen'er was born with a beautiful woman, but this woman...

For some reason, it is not suitable...

The next morning, Belin and Tong Xuan arrived in a hurry.

"Your Majesty, the phone number you mentioned has been made!"

"Is that right? Where is it? Let me see!"

Zhu Qizhen suddenly became interested. When Tong Xuan tinted out the electric light, he drew a drawing of the phone, but unexpectedly, it was made so quickly.

Tong Xuan took a bag from behind and said, "I have brought the things!"

After opening, there are two cylinders inside, connected by copper wire in the middle.

Zhu Qizhen took a rough look and found it was almost the same as he had imagined.

"Go, it's a try!"

The king and his minister came to the imperial study room, left a microphone inside, and then Tong Xuan took the other one and walked out and closed the door.

In fact, this thing is not a real phone call, it is at best called a phony tube.

Tong Xuan was also confused when he got the drawings. Since he had not answered the power, why did he call the phone?

In fact, Zhu Qizhen is used to it, and the phone is designed based on the principle of the sound tube.

Just as Tong Xuan was staring blankly with the drawings, a student from the Electric Power Research Institute suddenly said, "Isn't this the Listen Weng in Mozi's Book?"

When Tong Xuan heard this, he immediately went to find Mo Zishu. After reading it, he found relevant records in "Preparation of the Acupoints".

It is roughly a jar with a small mouth and a large belly. It is buried underground when used and covered with a thin layer of leather on the mouth of the jar. When it is necessary to detect, lying your ears on it to hear the movements around you.

If necessary, you can even let professional intelligence personnel sit in the jar and listen to the sound.

Sometimes, in order to reduce intelligence errors, blind people are often trained to perform tasks. Because blind people's hearing is often stronger than ordinary people, and movements within a radius of dozens of miles can be heard through listening urns.

Tong Xuan was inspired and continued to read ancient books. Soon, he also saw similar records in Shen Kuo's "Dream of Dreams and Bi Tan" in the Song Dynasty. However, he was no longer called Tingweng, but Yafu.

This is a special quiver, mainly used to detect enemy situations on the battlefield.

When you need to eavesdrop, take out an arrow, blow your breath, and pillow under your head at night, and you can hear the sound of people and horses within a few miles.

In addition, similar devices commonly used in the people include "listening to the tube", which is how the so-called "dividing ears in partition walls" come from.

But these devices are all separate, and no one has ever thought of connecting two listening tubes.

After Tong Xuan sorted out the records of the ancients, he quickly made the first sound cylinder based on the drawings provided by Zhu Qizhen.

The two earpieces are connected by copper wire. The copper has a very strong sound-guiding ability and can be heard clearly from a distance.

Zhu Qizhen patted the microphone, and then in his ear, Tong Xuan's voice came: "Master, can you hear it?"

"Heard, can you hear it?"

"I can hear it too!"

"Very good, come back!"

Tong Xuan took the microphone back to the imperial study room, and then saw Zhu Qizhen pull out a drawing.

"This is the real phone call!"

Belin only glanced at it and frowned.

Tong Xuan was puzzled, so he took two steps forward, and then he saw the dense parts and markings on the drawings.

Looking at the "phone" in your hand, it seems... it's not the same thing at all!
