The system is a broken bowl

"Yan'er, my eldest brother and I are bragging that we can make mobile phones. Can't we make voice calls with this thing?"

Being able to own a "radio station" is actually very impressive, but Song Chen is not satisfied yet.

"If you want to make a voice call, you need to activate the formation. But the martial arts cultivator's vitality can't activate the formation yet, so I can't help."

Yan'er blinked her beautiful big eyes. "Unless you use the formation to drive the formation, that can only be regarded as a landline phone, not a mobile phone."

Upon hearing this, Song Chen was overjoyed and even made voice calls on the landline! It cannot be used for marching and fighting, but it can be used at home to chat and talk on the phone! "Tell me, how to make this landline phone?"

Yan'er told Song Chen how to set up the two formations.

This is a formation that combines the imprinting formation and the setting formation. On the processed magic crystal, a sound transmission array is imprinted, but this array must be driven by another setting array.

In other words, the imprinting array is the telephone and the setting array is the battery. Although it is a bit troublesome, it is not a solution.

There are also formations in the mortal world that can be driven by spiritual objects, but they are all very simple formations, such as the Jiulong Sect's shielding formation and Jin Wanhe's Liuhe Spirit Locking Formation.

But Yan'er's sound transmission formation is very advanced. The disadvantage is that it cannot be driven without sufficient energy.

Of course, this energy-providing array requires magic crystals to be used as array eyes.

Therefore, each set consumes two magic crystals, and the production and use costs are very high.

who cares! Anyway, there are a lot of magic crystals now, and we are not using precious purple mid-grade magic crystals.

From now on, one will be installed in Lingbaozhai, one in Jinshaxuan, and one each in Shuozhou City Lord's Mansion and Imperial Palace.

"Yingjun, come and take a look. This is a mobile phone that can make long-distance voice calls. No! Now you can only call a landline."

Song Chen said excitedly.

He handed the finished magic crystal phone to Yan Yanjun.

"With this, you can make long-distance voice calls?"

Yan Yingjun was very surprised. He took the made intercom and looked around. Of course she didn't know the difference between a mobile phone and a landline, but as long as she could make calls, it was a magical device.

"Originally, I wanted to make a mobile phone for you that you can carry around with you. However, martial arts cultivators in the mortal world cannot drive formations, so they can only be placed in one place for use."

Song Chen felt a little regretful. "I plan to install four units in Lingbaozhai, Jinshaxuan, Shuozhou City Lord's Mansion and the Imperial Capital first. If they are still needed, then install them again."

"Really? That's great!"

Yan Yanjun was as happy as a child, and Song Chen still pretended to belong to the Dashun Empire, which made her very happy.

"Let's install two sets first and try the call effect."

Song Chen was also very excited.

Just now, he made four sets in one go. On the outside of the finished product, he also embedded a beautiful shell with crystal.

This is not just for aesthetics, but mainly for energy saving. Otherwise, the magic crystal will be exposed to the air and its energy will be quickly exhausted.

…

"What? This is the mobile phone Brother Song mentioned? Can it be used for long-distance calls?"

Curious Qin Wan asked questions rapidly.

"I want to install one for my sister-in-law in Jinshaxuan, and I need to find a special place to put it."

Song Chen didn't answer Qin Wan's question directly. He used facts to explain everything, and it was useless to explain for a long time.

Qin Wan brought Song Chen and Yan Yingjun to her and Ge Li's new house. "Just here, okay?"

"sure."

After Song Chen finished speaking, he immediately began to set up the formation. This is just an energy-gathering formation. It is not difficult to set up. The key is that the formation eyes need to use magic crystals.

"Yingjun, come and take a look. This is a mobile phone that can make long-distance voice calls. No! Now you can only call a landline."

Song Chen said excitedly.

He handed the magic crystal intercom to Yan Xijun.

"With this, you can make long-distance voice calls?"

Yan Xijun was very surprised and took the intercom and looked at it from left to right. Of course, she didn't know the difference between a mobile phone and a landline, but as long as it can make calls, it is a magic weapon.

"Originally, I wanted to make you a mobile phone that you can carry with you, but ordinary martial artists cannot drive formations and can only be fixed in one place for use."

Song Chen felt a little regretful. "I plan to install four units in Lingbaozhai, Jinshaxuan, Shuozhou City Lord's Mansion and the Imperial Capital first. If more are needed, then install more."

"Really? That's great!"

Yan Xijun was as happy as a child. Song Chen still had the Dashun Empire in his heart, which made her very relieved.

"Let's install two sets first and try the call effect."

Song Chen was also very excited.

Just now, he made four sets in one breath, and inlaid a beautiful shell with crystal on the outside of the finished product.

This is not just for beauty, but mainly for energy saving. Otherwise, the magic crystal will be exposed to the air and its energy will be exhausted quickly.

…

"What? This thing is the mobile phone that Brother Song said? Can it be used for long-distance calls?"

Curious Qin Wan asked questions like a machine gun.

"I want to install one for my sister-in-law in Jinshaxuan, and I need to find a place to put this thing."

Song Chen did not answer Qin Wan's question directly. Everything was based on facts. It was useless to explain for a long time.

Qin Wan took Song Chen and Yan Xijun to her and Ge Li's new house. "Let's do it here, okay?"

"Of course."

After Song Chen finished speaking, he immediately began to set up the formation. This is just an energy gathering formation. It is not difficult to set up. The key is that the center of the formation needs to use magic crystals.
