Zhang Nan pulled Cheng Yaojin. Although Zhang Nan had tried his best to prevent Cheng Yaojin from going further, Cheng Yaojin didn't care at all, and the strength level of the two people was not at the same level at all.

So Cheng Yaojin successfully took out a mobile phone from the carriage.

Just like a bear who got the corn, Cheng Yaojin didn't care about the pretty good-packed paper box. He directly tore open the paper box with his hands and then took out the phone inside.

"What's this?" Cheng Yaojin said, then raised his phone over his head and looked at it with the sun that had not yet come out, but he didn't see the reason.

"Okay, Brother Cheng, since you have opened this, I'll give it to you." Zhang Nan said helplessly as he looked at the box that had been broken into pieces of paper.

When Cheng Yaojin heard that Zhang Nan gave him this thing, he was immediately overjoyed. Although he didn't know what this thing was now, he knew that what Zhang Nan made would definitely not be bad, so he smiled and put his phone in his pocket.

As for all this, the ministers standing not far away all saw clearly. Although they wanted to come up and see what this thing was, they had no choice but to be as thick-skinned as Cheng Yaojin.

When he got the phone, Cheng Yaojin was like winning a battle, he returned to his original position with his own eight-character step. Yuchi Gong wanted to see the phone inside Cheng Yaojin's pocket, but Cheng Yaojin tightly covered his pocket and refused to let Yuchi Gong look at it. Yuchi Gong was about to have an attack, but helplessly, the door of the Tai Chi Palace Hall had already opened, and the ministers could only stand inside and wait for Comrade Li Er to come.

So Yuchi Gong also glared at Cheng Yaojin fiercely, as if complaining about Cheng Yaojin's stinginess.

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

Not long after, Comrade Li Er appeared in everyone's sight on time. Although Li Chengqian did this work during this period, after discussing the mobile phone yesterday, Zhang Nan knew that today's morning court would definitely be hosted by Comrade Li Er.

Of course, Zhang Nan knew it, which did not mean that the court officials knew it. Therefore, when the ministers saw Comrade Li Er, who was already in a semi-retired state, they also showed a confused look on the dragon chaise again.

Zhang Nan looked at Comrade Li Er with dark circles on his eyes and knew that Comrade Li Er must have not slept last night, so he definitely took Queen Changsun to study the phone all night.

"Ahem, okay, today I'm just showing up temporarily. You'll tell Chengqian that there's only one thing I'm here today." After Li Er said that, he took out his cell phone from his sleeve.

Then he held it in his hand and shook it.

"Do you all know what this thing is?" Comrade Li Er said, shaking the cell phone in his hand.

Ministers, look at me, look at you, they are silent. They really don’t know what it is for this little black box.

"Qingquan, please explain." Li Er kicked the ball to Zhang Nan with one kick. Zhang Nan felt that Li Er handed over the explanation to him, and the reason for 80% was that Li Er himself didn't know what else this thing could do besides calling.

However, since Li Er had the order, Zhang Nan naturally had to do it, so Zhang Nan walked out slowly and then took out his cell phone from his pocket.

"Sir, please see, this thing is the latest research of our Time Travel Sect. If it is useful, it is Qianli's voice transmission." Zhang Nan said with a smile.

When the ministers heard the voice transmission of thousands of miles, they all took a breath. If the divine wind crossbow that Zhang Nan used to take out, as well as hot air balloons and other things were within their tolerance range, the tool that can transmit voice transmission of thousands of miles is far beyond their imagination.

Shouldn't this kind of thing exist only in the legend?

"Don't question the ability of this thing, you guys, please don't question this. Regarding this, the emperor and I have been trying it for a long time yesterday, right?" After Zhang Nan said that, he looked at Li Er.

"That's right, you all have no surprises. At first I was as surprised as you, but yesterday I tried it with Qingquan, but as Qingquan said, it was able to transmit voices from thousands of miles away." Li Erdao.

"Okay, I won't go around in circles. I plan to pretend to be the major prefectures of our Tang Dynasty to facilitate them to report some urgent matters and equipment for our Tang Dynasty border. In this way, if someone violates our Tang Dynasty border, we can also transfer troops from the nearest prefecture." Li Er's speech was simple and clear.

When the ministers heard Li Er say this, they naturally could only bow down and say "The Emperor is wise."

"Of course, the emperor equipped the mobile phones for us at the border and major prefectures, which are the kind that can only be spoken. This is what I prepared for you all." After Zhang Nan finished speaking, he walked out of the hall of Tai Chi Palace. After a while, Zhang Nan walked in again. Of course, with Zhang Nan coming in with him, there were also several small eunuchs holding a lot of smartphones.

"With this thing, when you have nothing to do on weekdays, you only need a phone call and no longer have to send someone out. Of course, the emperor will find you all more conveniently. This is a small reward provided by the emperor to all the adults who do their best to the Tang Dynasty. Right, the emperor." After Zhang Nan said that, he blinked at Li Er.

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

So Li Er smiled and said, "It's right. This thing is extremely precious. I'll give you this phone, one for convenience, and the other is that you hope that your dear friends will be more diligent after getting such a precious treasure."

Hearing Li Er say this, the ministers hurriedly bowed and said, "I will definitely live up to the emperor's entrustedness."

"Okay, send all your phones to your dear friends." After Li Er said that, the little eunuch distributed mobile phones to the ministers one by one according to the names on the box. Of course, when he sent it to Cheng Yaojin next to Zhang Nan, Zhang Nan snatched Cheng Yaojin's mobile phone.

"Mr. Cheng already has one, so there is no need to give it to him." After Zhang Nan said that, he held the phone in his hand.

"Qingquan, what are you doing?" Cheng Yaojin saw Zhang Nan snatching his phone away, looking wronged. Of course, Cheng Yaojin's appearance was a crocodile tears for Zhang Nan, without any credibility.
