Before the polo tournament came, Qin Tian was doing these things.

Teach lessons to the crown prince, conduct psychological counseling treatment, and deal with some affairs in the court.

Classes and psychotherapy required non-stop talking, and after a few days, Qin Tian's voice became hoarse.

As soon as he opened his mouth, his voice was hoarse and low, and if he used too much force, he would feel a dull pain.

Being hoarse is not a big deal, but at this time, some training for the Mad Demon Army began.

As the soldiers and horses recruited by Qin Tian, the Mad Demon Army has to be trained for some time every year, and only by letting them keep training can they maintain a high level of combat effectiveness.

And every time he trained, Qin Tian had to come to the scene to command.

If you command, you need to speak loudly.

But now Qin Tian's voice is hoarse.

"Childe, if you don't train another day, anyway, there has been no war in my Datang recently, so it's okay to push it back."

Seeing that Qin Tian's voice was hoarse, Luo Huang wanted to delay the training of the Mad Demon Army.

However, Qin Tian shook his head: "The training of the Mad Demon Army cannot be wasted, if you don't practice now, you can only wait until after the polo match, but after the polo game, I may have other things, while I am in Chang'an City now, just train, the matter of the voice, you don't have to worry, I have a way." ”

When he said this, Qin Tian's voice was a little low, and it didn't sound particularly clear, Luo Huang was helpless when he saw him like this, so he could only nod and tell Hu Shibai that this year's training was going on as scheduled.

When Luo Huang went down to make arrangements, Qin Tian was here and locked himself in the laboratory again.

He's going to make a megaphone out.

His voice was hoarse and he didn't speak loudly, and if he could have a loudspeaker, he would only need to use very little force to spread his voice in the barracks.

The megaphone is still very simple, and it only took Qin Tian half a day to make one.

After making it, he took it and tried it: "Hey......"

After shouting, his voice was not as loud as in later generations, but in comparison, it was still several times louder than his usual normal voice.

Even the people in the courtyard in front of the house could hear it.

"It seems to be the voice of Xianggong?" In the backyard, when the ninth princess was chatting with Tang Rong and them, they suddenly heard a hey, which startled them.

"It's really Xianggong's voice, but how can it be so loud?"

Several women were very curious, and then they came to Qin Tian.

"Xianggong, was that your voice just now?"

Tang Rong asked curiously, and at this time, Lu Huaniang couldn't wait to ask: "Why is the sound so loud, we can hear it in the backyard." ”

Several women looked at Qin Tian with a look of anticipation, Qin Tian smiled: "This is a megaphone I made, which can amplify the sound of our usual speech several cups." ”

"Really, I'll try." Tang Rong took the megaphone a little excitedly, and then shouted: "Xianggong......"

She didn't think it was very loud, but after shouting like this, the sound was so loud that it shook her eardrums a little.

Immediately afterward, she was a little embarrassed.

I just shouted casually, but the voice was so loud, I was afraid that the entire Qin Mansion would hear it, right?

So, it's weird shy, and I'm embarrassed.

Tang Rong's cheeks turned red all of a sudden, and after shyly throwing the horn to Lu Huaniang, she covered her face and ran back.

Seeing her like this, Qin Tian couldn't help but smile, Lu Huaniang originally wanted to give it a try, but seeing Tang Rong's appearance just now, he had no choice but to suppress the impulse in his heart.

----------------------

With the loudspeaker, the training of the mad demon army can naturally be carried out as scheduled.

Early this morning, Qin Tian came to the barracks with people.

It wasn't very bright yet, and I could faintly see some fog.

In the barracks, the soldiers were already ready, waiting for Qin Tian to come to train.

Qin Tian stood on the stage, glanced at the soldiers below, and then took out his megaphone.

"Ladies and gentlemen, today is the day of your training, I want you to take out your twelve points of spirit for me, sweat today, there will be no bloodshed on the battlefield, you must train more in peacetime............"

Qin Tian said the opening remarks, as soon as he opened his mouth, the entire military camp could hear his voice, and those soldiers were stunned for a moment after hearing such a loud sound.

The voice...... Why is it so loud, how is this possible? ”

"That's right, when did the little grandfather's voice become so loud?"

"Hehe, you don't know this, the little grandfather made a loudspeaker, which can amplify the sound several times."

"No wonder, no wonder, the little grandfather is really amazing."

“…………”

Some of the soldiers were muttering, and Qin Tian was directing through the loudspeaker here, and all the soldiers could hear this voice, and because this voice was very loud, after the soldiers heard it, they all felt very shocked.

The treble is exciting, it is exciting.

Now Qin Tian's high voice, as well as his words of encouragement, made the mad demon army excited.

By the time Qin Tian finished speaking, they were already a little impatient to train.

"Let's go."

As soon as the order was given, the five thousand mad demon army began to drill, and Qin Tian commanded from time to time here, and the whole process was very imposing.

After the training, the next day, Qin Tian invented another fun thing, and the news spread in Chang'an City.

"Have you heard, Grandpa Qin invented a thing called a horn, which can amplify people's voices several times."

"It's not just several times, let me tell you this, this Suzaku Street is very long, isn't it, if someone talks at the other end with a loudspeaker, everyone on this end can hear it clearly."

"Hehe, let me tell you, if someone speaks with a megaphone, the entire Chang'an City can hear it."

“…………”

The people were just curious and chatting, but as a result, they gave this thing a myth while chatting, and after Qin Tian heard these remarks, he almost squirted out the water he had just drunk in his mouth.

"These people, isn't it too exaggerated, the loudspeaker can indeed amplify the sound, but it can't be transmitted from one end of Suzaku Street to the other, let alone anything...... The whole city of Chang'an. ”

Qin Tian was speechless, he had never seen people who liked to brag so much, were they a little too high to look at the loudspeaker?

Qin Tian secretly sighed that when the people were exaggerating, there were people in the palace here.

"Little grandfather, the saint announced that you have entered the palace, by the way, bring your megaphone with you."
