[Heh, two years...]

"Two years is too tight, there's a lot to do. How about three years? That should be enough, right?"

The emperor looked uncertainly at Chuanhai and Marquis Changxing. The two stammered, their eyes constantly glancing at Chuanwen. Would three years be enough?

Chuanwen wore a standard professional smile, but inwardly he was thinking: 【Heh.】

The emperor's lips twitched. "Five...five years?"

Chuan Hai and Marquis Changxing continued to stammer, while Chuan Wen thought to himself: [I'll take the lead in shirking responsibility.]

The veins on the emperor's forehead throbbed; he couldn't wait until the emperor died!

"Just five years!"

The emperor finished speaking through gritted teeth, turned around and left, leaving behind a bewildered Chuanhai and Marquis Changxing, as well as Chuanwen, who wore a professional smile but was inwardly relieved that the emperor was finally gone.

Chuanwen went to dance happily, while Chuanhai and Marquis Changxing went from kneeling to sitting, looking at each other speechlessly, feeling utterly hopeless.

When Chuanwen's new research came out, the students in the girls' school's research class also came to join in the fun. However, they didn't dare to sing and dance as boldly as Chuanwen. They just clapped and cheered from the sidelines, and a few curiously looked around the sound system.

Just as everyone was having a lively time, Hua Jing was also attracted by the sound. He glanced at the black box from afar and was filled with curiosity.

"A small box like this can't even fit a person. How come there's a loud noise coming from inside? But... it's certainly strange, but it doesn't seem very useful."

Hua Jing was wondering if the female student was researching this kind of thing when a guard behind her suddenly seemed to remember something, and stepped in front of her, glaring fiercely at the black box as if it were something very dangerous.

"What's wrong?"

Hua Jing and another guard were puzzled. The man said anxiously, "Princess, leave quickly! That's an extremely powerful weapon!"

arms?

Hua Jing looked at the black box, as well as the cheerful Chuanwen and the group of people, and really couldn't see what danger the thing was.

But the guard's nervousness seemed genuine, so Hua Jing had no choice but to leave first.

The three of them were speaking in a Western Regions dialect, so the people around them didn't know what they were talking about. They only saw them chatter away for a while before leaving as if facing a great enemy, and wondered if the three of them were out of their minds, being so afraid of such a happy scene.

Looking at their clothes, I realized they weren't from the Great Jin. I couldn't help but sigh. The Great Jin was a vast and resource-rich land, full of all sorts of strange things. Yet these people from the barbarian lands all looked like country bumpkins when they first arrived. They probably mistook the black box that made the sound for something terrifying, since even they had never seen such a thing before. They were quite startled when the black box first made that sound.

The guard only relaxed after they had walked two streets and could no longer hear the music.

"What exactly happened?"

Hua Jing couldn't help but ask, and the guard took out a storybook from his pocket, quickly flipped to a certain page, and handed it to Hua Jing, "Please take a look, Princess!"

Although it was written in the script of the Great Jin Dynasty, Hua Jing recognized some of it. Following the direction the guard pointed, he saw a passage describing a weapon that could emit sound and adjust the volume to produce sound waves of different frequencies. These sound waves were inaudible to them, but those affected by them could experience dizziness at best, and internal organ rupture at worst, killing people invisibly!

Hua Jing's face grew paler and paler as he looked at the music. Upon reflection, he realized that the loud singing had indeed made him feel a little dizzy!

If Chuanwen was researching such deadly weapons, then the Emperor of Jin's strict guard against her would be completely understandable!

Hua Jing couldn't even imagine the impact it would have if this weapon were used on the battlefield!

"But this is just a storybook, it's fake!"

The other guard didn't believe that such a weapon existed, capable of killing without leaving a trace or visible wound; he thought only a god could do that.

"Where did you get this storybook?"

Hua Jing looked at the guard with a deep gaze. The guard scratched the back of his head, a little embarrassed, "I saw that these storybooks are quite popular when I went out for a stroll these past few days, so I bought a few."

Hua Jing glanced at the book's signature—"Family Heirloom."

"family heirloom?"

Hua Jing frowned slightly. This name was clearly an alias; he just didn't know who it belonged to. If he knew who this person was, he might be able to ask him whether these weapons were merely his imagination or if there was any basis for their existence.

"Go and find out who owns this family heirloom."

After giving instructions to the two men, Hua Jing went back to study the storybook, wondering if there were any other weapons, and whether the Great Jin Dynasty had produced them yet.

Late at night, Hua Jing carefully read the storybook, and then let out a deep sigh.

Besides the sonic weapon, the story also features so-called bombers that can fly like birds, capable of destroying a city with a single bomb, as well as sniper bombs that can lock onto a location and destroy a small country with a single strike, all of which terrified Hua Jing.

It seems that the Great Jin Dynasty has not fully figured it out yet. Otherwise, in the previous battles with them, they could have simply destroyed their cities remotely without needing to use spears and arrows!

However, if the Great Jin Dynasty were to research those things, not only the Western Regions, but all the countries in the world would no longer be a match for the Great Jin Dynasty!

Thinking this, Hua Jing quickly picked up the banknotes and wrote a letter. She didn't care whether her brother's surrender to Da Jin was genuine or not; now he had to make it a genuine surrender!

If you want to go against the Great Jin, you really have to think twice about whether they can take a beating!

Hua Jing had just finished writing the letter when the Minister of War arrived. She was puzzled. Why would the Minister of War want to see her so late? She wasn't even familiar with the Minister of War!

“Princess Huajing, the Imperial Guards have arrested a group of thieves. Because the thieves have some connection with you, the Emperor has sent me to invite you to come and see them.”

The Minister of War smiled, which only confused Hua Jing more. How could she have anything to do with thieves?

"Does Your Excellency suspect that I instructed people to steal property from the Great Jin Dynasty?"

Although Hua Jing really wanted to go to the girls' school, she knew what she should and shouldn't do. Besides, she had already chosen her husband, so she only needed to plan slowly and didn't need to steal at all.

"Of course not, the princess will know once she goes to see for herself."

The Minister of War naturally didn't think Hua Jing would steal things from the girls' school, but the group they had captured were, after all, from the Western Regions, so it was better to have the Western Regions princess handle the situation in front of them to save face for both sides.

The Minister of War led Hua Jing to the city wall, where the emperor and some officials were present. They stood on the high city wall, looking out over the wall, their smiles inscrutable.

Hua Jing found it strange. After exchanging greetings, the emperor pointed to the area outside the city and asked her to look. At first, Hua Jing didn't see anything special; it was just some people surrounded by the Imperial Guards. But when she saw the faces of those people clearly under the torchlight, she was startled.

Although those people were all dressed in the attire of the Great Jin Dynasty, their distinctive features revealed that they were not from the Great Jin, but rather from the Western Regions, where people were constantly exposed to wind and snow.
