Changle returned to the dormitory.

Quietly came to Su Chen's bedroom and found that Su Chen had not come back yet.

Changle picked up the mobile phone and pressed the number one button directly according to Su Chen's instructions.

Toot ~ Toot ~ Toot ...

There was a beeping sound coming from the microphone of the phone.

"Changle, I'm Su Chen, and I'm on my way home now."

Hearing Su Chen's voice, Changle's face was full of joy.

"Childe, my father has decided to let Uncle Qin try the elixir."

Changle's words made Su Chen obviously stunned for a moment, and then thought of the Qin Clan's heroes.

"Changle, it's Qin Qiong and Qin Shubao, right?"

"Well, it's Ji Guogong, Qin Qiong and Qin Shubao."

Changle replied in the affirmative.

"Okay, I know, you wait for me at home, I'll go buy some fresh fruit."

The fresh fruit in Su Chen's mouth was naturally heard as a fairy fruit by Changle.

"Well, Changle is at home waiting for his son to come back."

Su Chen hung up the phone with a smile, and promised Changle's voice transmission device, Su Chen had already bought it, and bought fifteen pairs at one time, that is, thirty walkie-talkies.

Parking the car on the side of the road, Su Chen began to search for Qin Qiong and Qin Shubao's information.

Qin Shubao Su Chen is naturally no stranger, but a figure at the level of a door god.

After some searching, Su Chen was sure that Qin Shubao was suffering from all kinds of injuries, internal injuries, external injuries, internal and external injuries.

It is impossible to heal at one time, even if Su Chen takes him to his own world and then sends him to the hospital for diagnosis and treatment, it will take a process.

The biggest advantage is that people in the Tang Dynasty basically have no antibodies to any drug, that is, all drugs have twice the effect with half the effort.

Su Chen still drove to the pharmacy in the morning.

"Young man, you're here again?"

Hearing the words of the eldest sister in white, Su Chen smiled a little bitterly.

When other shops see customers coming to the door, they are eager to welcome them, this one is so personal.

"Eldest sister, please take some special medicine for bruises, blood circulation and blood stasis, and treatment of internal and external injuries."

"Young man, you're quite active, have you hurt your muscles and bones?"

Su Chen touched his nose in embarrassment when he heard this, and replied.

"Yes, it's really nerve-wracking."

"These are enough, all the internal and external applications are available, try to go to the hospital to see, young people, don't work too hard."

"Thank you, big sister."

Su Chen finally knew, this was really a knife-mouthed, tofu-hearted eldest sister.

After Su Chen paid, he went out with the bag, and the eldest sister watched Su Chen drive away.

There was a puzzled expression on his face, this young man drove such an expensive car, and he was reluctant to go to the hospital?

It's really weird.

Not far from the complex, there is a boutique fruit shop.

Since it is called a boutique fruit store, the price of the fruit in it is naturally much higher than the market price.

Su Chen is no longer the Su Chen who used to spend a penny into two cents.

I picked a few of each fruit, and finally I picked two watermelons and a small pot of strawberries.

Su Chen drove into the community, and when he got out of the car, he dialed Changle's phone.

"Changle, Mo dozens of numbers, and I will appear in front of you."

Changle happily walked to the door, took a deep breath, and began to count silently.

I never thought that Su Chen would not play cards according to the routine, and before Changle could count the general, Su Chen had already pushed the door in.

"Changle, these are walkie-talkies that can transmit sound."

"It's enough to transmit sound for twenty miles!"

When Su Chen's words landed, Changle pounced happily.

Originally, it was promised to the father and the queen mother, but it was only ten miles and eight miles, but I never thought that the son would give another surprise, and the transmission could reach twenty miles.

The surprise that Changle didn't expect was actually still to come.

Su Chen carefully explained to Changle how to use the walkie-talkie.

The mobile phone, which is much more complicated than the walkie-talkie, has already played with Changle, and it is much easier to learn to use the walkie-talkie.

It didn't take long for Changle to fully master the use of walkie-talkies.

"Changle, you have a few left here, and when the time comes, you can call the palace maids and chamberlains without leaving the palace."

Changle nodded when he heard this, and carefully took out three walkie-talkies, plus one in Changle's hand, which was four.

In order to charge so many walkie-talkies, Su Chen specially purchased ten multi-functional sockets.

There was also a bold idea that rose in Su Chen's mind, could electricity be transmitted to Changle's dormitory through wires?

In order to prove whether his idea was true, Su Chen took action directly.

After a few sockets were connected, they passed through Changle's bed, and the sockets of all chargers were neatly placed on the desk by Su Chen.

The moment that made Su Chen clench his fists excitedly finally came, and after turning on the switch, all the power indicators lit up.

There is no doubt that electricity can be transmitted to the Changle Dormitory.

In this way, there are too many things that can be transmitted to Datang in the future.

Su Chen charged all the spare batteries.

Each walkie-talkie comes with a spare battery, and a headset, the battery is indispensable, headphones, Su Chen thought that for an era like Datang, there was really not much need.

Su Chen adjusted all the walkie-talkies to a frequency and band.

"Okay, you can send it to Your Majesty and the Queen Mother, as for how to distribute it, let Your Majesty and the Queen Mother call the shots."

"Hmmm......"

Changle nodded happily, picked up the bag, and was about to leave.

Su Chen remembered the medicine he had purchased specifically for Qin Shubao.

So they were handed over to Changle.

Changle happily got into the carriage and went straight to the Lizheng Palace.

"Father, mother."

After getting off the bus, Chang Lexing hurriedly went straight to the Lizheng Palace.

Li Shimin and Empress Changsun also heard joy in Changle's voice.

The two looked at each other and smiled, knowing that Changle must have brought the sound transmission device.

Sure enough.

When Changle put a big bag of walkie-talkies on the table.

Li Shimin called a good guy.

"Changle, these are all sound transmission instruments?"

"Father, these are all sound transmission instruments, the son has a total of thirty departments, the son leaves four departments, and the remaining twenty-six parts, the son said that they will be distributed by the father."

"Good ......"

Li Shimin nodded with great joy.

Picking up a walkie-talkie, his eyes were hot, and he looked at it carefully.

After Changle explained carefully, Li Shimin and Empress Changsun both mastered the method of use.

It's just to turn on the switch, to speak, to press the side with the right hand, and the voice falls to the ground, and it is just released in time.

Li Shimin and Empress Changsun didn't expect that such a magic weapon would be so easy to use.

"Father, mother. Childe just said that this magic weapon can transmit sound for more than 20 miles......"

When Li Shimin heard this, he nodded happily. In order to argue the authenticity, Li Shimin immediately sent Li Junxian to ride his Qingya horse, holding a walkie-talkie, galloping on horseback, all the way to the south.
