After an original dinner, Liu Lang carried out the romance to the end, and took Mu Xueqing to enjoy the beautiful scenery in the secret realm of Xingyue, but after seeing the scenery for a while, the two couldn't help it, returned to the new bed in their new home, and slammed their hearts fiercely.

After Mu Xueqing was exhausted and fell asleep, Liu Lang's consciousness entered the mortal immortal prison.

At this time, the dinner in the mortal immortal prison had just ended, He Weifeng and Sun Zongliang were cleaning up the dishes in the cafeteria, and it was obvious that after a day of consideration, Sun Zongliang also chose to bow to reality.

Now Sun Zongliang is penniless, he can't even eat if he doesn't help in the canteen, and after thinking about it, he still feels that he must solve the current predicament first.

As for face, can it be eaten as a meal?

Liu Lang didn't stimulate Sun Zongliang, took two glances outside the cafeteria, and left.

There is a saying that there are no rules, there is no circle.

After being promoted to the warden of the mortal immortal prison, Liu Lang had a certain change in his thinking, and he realized that if he wanted to really manage the mortal immortal prison well, he relied on a perfect system.

Sun Zongliang has already been sentenced, and the sentence is extremely heavy, which can be regarded as getting the punishment he deserves, there is no need to deliberately target Sun Zongliang and give Sun Zongliang small shoes to wear.

After the inspection, Liu Lang came to the warden's lounge, and after waiting for a while, Ke Qingmiao came to the mortal immortal prison with several newly developed sound transmission stones with projection functions.

"Brother, the real-time projection function in the chat room, after testing, is basically no problem, according to the number of people in the mortal immortal hell, I made these more than thirty first. You can let everyone try it. Ke Qingmiao put the new type of sound transmission stone on the table, and then introduced: "This kind of sound transmission stone can clearly transmit the user's image in the chat room, even if others use the old sound transmission stone that has not been transformed, they can also see the projection." ”

"I'll see what it looks like, Master Ke, let's try it first. Liu Lang was not in a hurry to send these new sound transmission stones to the prisoners of the mortal immortal prison.

Because the prisoners in the mortal immortal prison are all gold medal anchors, and the audience is quite wide, once they use it, thousands of people will see it.

Liu Lang has to personally confirm that there is nothing wrong with this projection function before it can be promoted on a large scale.

"Okay!" Ke Qingmiao picked up a sound transmission stone and set up a chat room inside the sound transmission stone.

Liu Lang entered Ke Qingmiao's newly established chat room as a tourist, and soon, a clear projection image, centered on Liu Lang's sound transmission stone, spread out, and it was 3D, and another Ke Qingmiao appeared in the room, if you don't distinguish carefully, I really don't know which one in front of you is the real Ke Qingmiao.

Afterwards, Ke Qingmiao tried to say a few more words.

At the same time as the projection, the sound is also clearly transmitted through the sound transmission stone, and the sound is completely synchronized with the picture, without the slightest flaw.

"Immortals are immortals, and this 3D projection technology surpasses the mortal world at once. Liu Lang couldn't help but secretly sigh in his heart, the creativity of the alchemist was obviously not comparable to mortal technology.

What they lack is just a direction, as long as they have a direction and do better than the mortal world, it is very normal.

After trying the functions of the new sound transmission stone and making sure that there was no problem, Liu Lang asked Ke Qingmiao to wait for a while, and then he distributed the more than thirty new sound transmission stones to the prisoners in each cell, and at the same time taught them how to use the projection.

I heard that a new feature has been added to the Heavenly Court chat room, and the gold medal anchors represented by Guang Yaozi and Zhang Daoling are rushing to start live broadcasting one by one like chicken blood.

Past experience has taught them that the emergence of a new feature will inevitably bring huge wealth.

Seeing everyone's live broadcast in full swing, Liu Lang nodded slightly.

Before the Chinese New Year's Eve, with the advent of the chat room projection function, the traffic of the Heavenly Court chat room will surely usher in a huge surge, which is almost conceivable.

After Liu Lang returned to the warden's lounge, he found that Ke Qingmiao was holding a sound transmission stone, watching Zhang Daoling's live video, and after watching it for a while, he switched to Guang Yaozi's room.

As a partner, Ke Qingmiao also hopes that the new functions of the Heavenly Court chat room can be sold well, so he is also very concerned.

"Master Ke, have you ever thought about using this projection function in other ways?" Liu Lang asked Ke Qingmiao.

"Use it in other ways, you mean?" Ke Qingmiao hurriedly exited the chat room, raised his head and asked Liu Lang. Liu Lang's best thing is to capture business opportunities, and his intuition told Ke Qingmiao that he seemed to be making money again.

"Now, using the sound transmission stone to transmit messages, or simply sound transmission, can completely apply the projection function to ordinary sound transmission, I believe that in technology, it is not difficult to achieve. Liu Lang came up with an idea.

"You mean, develop this function, and then charge the function fee?" Ke Qingmiao instantly understood what Liu Lang meant.

"That's right. Liu Lang nodded.

Projection sound transmission, in fact, is equivalent to the video phone of the mortal world, there must be a certain market in the heavenly court, in addition to charging a certain function fee, if you want to use this function, you must also update the sound transmission stone, this is another profit point, just like the mobile phone in the mortal world, with the improvement and optimization of the function, it is constantly replaced, the upgrading of the sound transmission stone, there is also a huge market.

"This matter has to be studied carefully. After receiving an affirmative answer, Ke Qingmiao's eyes flashed with excitement.

In the past, grandma didn't hurt, uncle didn't love, and there was no oil and water to fish for the sound stone business, finally ushered in spring, a heavenly court chat room has made him raise his eyebrows, if this projection sound transmission function, and can make money, then he is really big.

After talking about the sound transmission stone, Ke Qingmiao suddenly remembered something else.

"Brother, have you gained a lot of fire elemental power in the Cloud Wonderland?"

"That's right, what, Master Ke, you also want the power of the fire element?" asked Liu Lang.

"It's not. Ke Qingmiao shook his head and said, "I heard that you were at the gate of the Youyun Immortal Realm, and you sold half of the sound transmission stone at a high price, and the other half was left to a yellow-level alchemist named Xu Yuan?"

"That's right, at that time, most people thought that I couldn't find the power of the fire element in the Youyun Wonderland, only Xu Yuan was optimistic about me, and when he talked to me, I naturally wanted to keep it for him, even if I got less money in the end, it didn't matter. Liu Lang explained.

"That's the truth. Ke Qingmiao expressed her understanding of Liu Lang's approach, and then asked, "Do you know who Xu Yuan's teacher is?"
