Zhang Nan pulled Cheng Yanjin, although Zhang Nan had already tried his best not to let Cheng Yanjin go further, but Cheng Yanjin didn't care at all, and the strength level of the two people was not on the same level at all.

So Cheng Yanjin still managed to take out a mobile phone from the carriage.

Just like a bear that got the bud rice, Cheng Yanjin didn't care about the cardboard box with good packaging, and directly tore open the cardboard box with his hand, and then took out the mobile phone inside.

"What is this?" Cheng Yanjin said, he raised the phone above his head, and looked at it with the sun that had not yet fully come out, but he didn't see why.

"Okay, Brother Cheng, since you have opened this, then this will be given to you." Zhang Nan looked at the box that had been broken into pieces of paper and said helplessly.

As soon as he heard that Zhang Nan gave this thing to himself, Cheng Yanjin was immediately overjoyed, although he didn't know what this thing was now, but he knew that what Zhang Nan made would definitely not be bad, so he put the mobile phone in his pocket with a smile.

And all this, the ministers standing not far away saw it clearly, although they also wanted to come up and see what this thing was, but helplessly, they didn't have such a thick skin as Cheng Biting Jin.

got the mobile phone Cheng Biting Gold, as if he had won a battle, and returned to his original position with his own figure-eight steps. Wei Chigong wanted to see the mobile phone in Cheng Bitingjin's pocket, Cheng Biting Jin tightly covered his pocket, not letting Yu Chigong look at it, Yu Chigong just wanted to have a seizure, but helplessly, the door of the main hall of Taiji Palace had been opened, and the ministers could only stand inside and wait for Comrade Li Er to come over.

So Yu Chigong also glared at Cheng Biting Jin fiercely, as if he was complaining about Cheng Biting Jin's stinginess.

Zhang Nan also parked the carriage outside, and then entered the main hall and stood in his own place.

It didn't take long for Comrade Li Er to appear in everyone's sight on time, although this work was done by Li Chengqian during this time, but after discussing the matter of mobile phones yesterday, Zhang Nan knew that today's morning dynasty would definitely be presided over by Comrade Li Er.

Of course, Zhang Nan knew, but it didn't mean that the courtiers knew, so when the ministers saw Comrade Li Er, who was already in a semi-retired state, sitting on the dragon chair again, they also showed puzzled looks.

Zhang Nan looked at Comrade Li Er with thick dark circles under his eyes, and knew that Comrade Li Er must not have slept last night, and he definitely took Empress Changsun to study his mobile phone all night.

"Ahem, okay, I'm just a temporary appearance today, you still have to talk to Cheng Qian later, I came over today for only one thing." After Li Er finished speaking, he took out his mobile phone from his sleeve.

Then he took it in his hand and shook it.

"Do you Aiqing know what this thing is?" Comrade Li Er shook the mobile phone in his hand and said.

Ministers, look at me, I look at you, they are all silent, they really don't know what the use of this little black box is.

"Qingquan, you can explain." Li Er kicked the ball to Zhang Nan, Zhang Nan felt that Li Er handed over the work of explaining to himself, and 80% of the reason was because Li Er himself didn't know what this thing could do except make a phone call.

However, since Li Er had an order, Zhang Nan naturally had no choice but to do it, so Zhang Nan walked out slowly, and then took out his mobile phone from his pocket.

"Ladies and gentlemen, please see, this thing is the latest thing we have researched through the gate, if anything, it is a thousand miles of sound." Zhang Nan said with a smile.

Hearing the sound of thousands of miles, all the ministers gasped, if Zhang Nan took out the kamikaze crossbow before, as well as hot air balloons and other things, they were still within their tolerance, and now this tool that can transmit sound for thousands of miles is much beyond their imagination.

Isn't this kind of thing supposed to exist only in legends?

"Don't question the ability of this thing, about this, the emperor and I have been trying it for a long time yesterday, right, Your Majesty." After Zhang Nan finished speaking, he looked at Li Er.

"That's right, you Aiqing don't need to be surprised, at first I was as surprised as you, but yesterday I tried it with Qingquan, but as Qingquan said, it can spread the sound for thousands of miles." Li Erdao.

"Okay, I won't go around in circles, I plan to install this thing on our major state capitals in Datang, so that they can report some urgent matters, and equip us on the border of Datang, so that if anyone violates my Datang border, we can also transfer troops from the nearest state capital." Li Er's speech was simple and clear.

Hearing Li Er say this, the ministers naturally could only say "The emperor is wise".

"Of course, the mobile phones that the emperor has equipped us with for the border and the major state capitals belong to the kind that can only speak, and this is what I have prepared for you adults." After Zhang Nan finished speaking, he walked out of the main hall of Taiji Palace, and after a while, Zhang Nan walked in again, of course, with Zhang Nan came in, there were also a few little eunuchs, holding a lot of smartphones.

"With this thing, when you adults have nothing to do on weekdays, if you want to go out and get together or something, you only need a phone call, and you don't need to send someone out at all, of course, the emperor will also find it more convenient for you to find your adults, this is a small reward that the emperor provides to you to do your best for the Tang Dynasty, right, the emperor." After Zhang Nan finished speaking, he winked at Li Er.

Li Er naturally didn't expect Zhang Nan to have such a hand, but since Zhang Nan gave Li Er all this favor, how could Li Er not accept it?

So Li Er said with a smile: "That's right, this thing is extremely precious, I will give you this mobile phone, first, for convenience, and secondly, I hope that you Aiqing can be more diligent after getting such a precious treasure." ”

Hearing Li Er say this, the ministers hurriedly bowed their hands and said, "The ministers will live up to the emperor's trust." ”

"Okay, let's send all the mobile phones to all Aiqing." After Li Er finished speaking, the little eunuchs distributed mobile phones to the ministers one by one according to the names on the box. Of course, when it was sent to Cheng Biting Jin next to Zhang Nan, Zhang Nan snatched Cheng Biting Jin's mobile phone.

"Master Cheng already has one, so I don't need to give him this." After Zhang Nan finished speaking, he took the mobile phone in his hand.

"Qingquan, what are you doing?" Cheng Biting Jin saw that Zhang Nan had snatched away his mobile phone, and looked wronged, of course, Cheng Biting Jin's appearance belonged to crocodile tears for Zhang Nan, without the slightest credibility.
