Empress Changsun returned to the imperial city after visiting a friend, and told Li Er, who had been waiting, the good news.

Li Er's heart was very broad, if he couldn't even find out the results of Chen Chu at that time, then he would have no choice, and he would also explain to his father.

Father, you see, Chen Chu can't help it, and we can't help it, these assassins are too cunning.

Of course, he swore that there would never be a next time for this kind of thing, it would be shameful enough not to find the assassin once, and Li Er would be able to hit the wall again.

And this is only the worst outcome, it is very likely that Chen Chu can find clues, so everyone is happy.

I'm afraid that when the time comes, the ministers will force themselves to give Chen Chu a reward, how to give the reward, I am worried.

"It's called a horn, it uses the kind of battery of a flashlight, and it's very loud, and it scared me today, it's so loud."

Empress Changsun handed the horn to Li Er, and then talked about what she had seen and heard at the time.

"You don't need to speak loudly to thousands of people? The sound is heard in the streets outside the house? ”

Li Er tried to put his mouth over, and shouted in a loud voice, and suddenly a loud voice came from the huge room, and the echo wandered around, startling the two of them.

"I'll go, this thing is damned!" Li Er's pupils shrank, he couldn't care about anything, the two went out of the palace all the way, and Li Er directly began to gather the guards in the imperial city.

Thousands of people were summoned and gathered in an empty square with bright lights.

He shouted a few times through his trumpet, and then asked the army if they heard his orders.

Many sergeants were shocked one by one, staring at this novelty in Li Er's second hand in stunned dismay, and everyone said that not only could they hear it, but Li Er's voice was countless louder than usual!

Li Er was overjoyed, and immediately found a palace wall that was nearly two hundred meters away from him, and he put down the horn and yelled in his own voice, asking the soldiers on the palace wall if they heard it.

As a result, the soldier remained motionless and did not react, apparently not hearing him at all.

Then Li Er used the horn again, and almost a second later, the sergeants on the palace wall reacted one after another, saying that they had heard the voice.

"Good stuff, haha, good stuff!"

Li Er was overjoyed on the spot, Chen Chucai invented the easy-to-use so-called manganese steel shovel, and now this thing has appeared again, which is a powerful tool for communication in large places!

From small project gatherings to large and small project gatherings, as large as the army's order deployment, Li Er trembled with excitement.

There are tens of thousands of officers and soldiers in the barracks at every turn, and the usual military orders must be issued layer by layer, and the orders issued by the chief officer are constantly passed on by several heralds, or the flag is displayed, which is not only troublesome, but also often prone to chaos.

But with this big killer, all voices in the chaotic and noisy barracks can be suppressed immediately!

Li Er has already asked, two or three hundred meters away, the sound of this thing will be much quieter, but it is completely enough, the longer distance, it is basically out of sight, such a large range of orders and prohibitions is completely enough.

It will give the army a huge boost in combat effectiveness!

You must know that soldiers usually not only need to train swords and guns to assassinate, but also need to master the formation, formation, flag language, etc., and it takes up too much of their time to recognize the formation and flag, but once there is this horn, it will make everyone much easier!

Large-scale festivals, celebrations, temple fairs, outings, sacrifices, etc., due to the chaos of the crowd, often cause stampedes and other incidents, there is this horn by the unified management of the government, will avoid a lot of trouble, so that the people can rest assured to gather.

Communication between hundreds of meters, which used to require both sides to run close to tens of meters before they can communicate, and even some slightly more complex information must be communicated in person, and now this situation will also be improved.

Catching thieves, suppressing bandits, forging cities, caravans, etc., who doesn't need this? A command can be heard within a radius of 100 meters below, this has to be shouted at the top of the voice, not to mention the slightly more complex terrain, even if it is flat ground, how loud is it?

Even if you shout loud enough, how many words can you shout? It didn't take long for my voice to be hoarse.

Li Er rubbed his hands, like a king-sized green-headed fly, his heart was itching, and now his mind was full of what to exchange with Chen Chu.

Don't say too much, let's change it to ten or eight first, he will immediately be put into the hands of the guards of the imperial city, and if there is a surplus, it will be supplied to the defenders of Chang'an.

Yilai Inn, people are very excited.

It's been a few days since the round of 64, and today, everyone's reward is long overdue.

"Look what's it!"

Everyone was almost more excited than they had won, rubbing their hands frantically, staring at a box the size of a bookcase and being bundled up.

The first thing to be placed on top were two oval mesh with long handles, and next to a bag there were a total of nine strange things that I don't know what they were, white and umbrella-shaped, very light.

"What is this?" Shangguan Yi was directly stunned, and his intuition told everyone that this must be an excellent thing, but he had never seen this thing.

"I know this thing, I know!" A man suddenly became excited.

"This is called badminton, this is a racket, this is a badminton, and there are actually nine of them! Now Chang'an City doesn't know much about badminton, and it hasn't become popular yet, but Luoyang has spread this thing crazy! ”

"Just before Luoyang held a badminton competition, Lord Chen sent a lot of things in one go, and it is said that when those good things were transported from Chang'an, there were several cars."

Another new kind of competition? Generous rewards?

People's ears pricked up all of a sudden, and they were just a general freshness to this shuttlecock, but now the whole thing is full of enthusiasm.

Let's take a look at the chess game, how strong is the support of Lord Chen? Almost every round winner has a prize, and it is basic to keep winning and making a fortune.

"How is this thing played, it looks like a two-player game?"

People chattered and discussed, and the shopkeeper was also watching, and he was also very excited, and at this time he had already ordered the men to make a big meal, and tonight was to entertain everyone well, and see if he could get any good things.

"Don't rush yet, there are good things to come." Someone spoke, and this lowered everyone's discussion a little.

"Milk! This is what is distributed to children once every three days in Dongcheng during this time. ”

People were shocked, only to see six cartons of milk lying neatly, beautiful white packaging, with a straw, because of the imperial court's generous distribution, now no one in the whole Chang'an does not know this thing, but many people are indeed seeing it for the first time.

"Now you can see this thing on the market, but it is very, very rare, it is said that the taste is not good, but it is very nutritious, Lord Chen said that a box of this can top a meal, or the kind of full meal."

"Although the taste is not good, it is better because it is nutritious, and everyone has never tasted it, so it is quite gluttonous." Everyone swallowed their saliva, what tasted bad, it was all a pretext, how bad could the things that Lord Chen took out be worse?

Just open your eyes to this, and you have to try it.
