Lu Cheng didn't expect that the surveillance system in the camp would come in handy on the first day it was installed, and it was the thermal imaging camera that worked.

Anything can happen in the world of magic, and Lu Cheng has already foreseen this... But I didn't expect someone to be invisible.

Luckily, magic can still be dealt with by science, and the two intruders have been captured and locked up alone in an interrogation room made of a shipping container.

"Do you know who they are?"

When Lu Cheng arrived outside the interrogation room, the personnel in the camp were already interrogating the two uninvited spellcasters.

"All I know is that they come from the Gmansis Secret Order, and the woman has been silent, and the other man has always said useless things." A responsible officer said to Lu Cheng.

"The Gmansis Secret Order? But that woman is a little familiar, no... It shouldn't be said familiar. ”

Lu Cheng looked through a one-way coated glass at the two people in the interrogation room, which had a total of two small rooms, and the two captured spellcasters were separated for interrogation.

The female spellcaster, Lu Cheng, could feel a familiar aura in her, and this 'aura' was real.

After the Holy Crystal strengthened Lu Cheng's senses, Lu Cheng could feel the flow of magic power.

This feeling is also a necessary trait for the caster.

"The words of the Secret Festival must have something to do with that groundhog, and you continue to keep an eye on them."

Lu Cheng walked out of the interrogation room quickly, and walked straight to the research area where Noi lived.

As soon as Lu Cheng sent Noi back to their residence, heart-rending screams rang from inside the room.

"Lucheng!!"

The scream came from Charlotte, the groundhog, who jumped off the table as soon as she saw Lu Cheng and ran in front of Lu Cheng with her hands and feet.

"What's going on?" As soon as Lu Cheng's words fell, Charlotte's two little paws grabbed Lu Cheng's trouser legs.

"The slate you gave me called the mobile phone is not responding!"

Charlotte tugged at Lu Cheng's trouser legs and tried to pull Lu Cheng into the room.

Lu Cheng had no choice but to let the groundhog pull him to the side of the desk, and then Charlotte climbed up to Elena's bed with her little paws, and then climbed from Elena's bed to the desk next to her.

Charlotte climbed onto the table and picked up her phone and held it in front of Lu Cheng.

"Is it broken?" Charlotte's furry face was full of worry.

"It's just that the electricity is out, and the things we make don't break so easily, as long as you don't wash them in water."

Lu Cheng glanced at Charlotte's mobile phone, and unsurprisingly was out of power by this groundhog, Lu Cheng took out the charger and connected the phone, and then plugged it into the electrical interface at the head of the bed.

In less than three seconds, under Charlotte's surprised gaze, the originally dead mobile phone was resurrected again.

"This thing needs magic to recharge just like the golem?"

Charlotte also knows that the 'energy' of her mobile phone is not infinite, but unfortunately her body as a groundhog does not have any magic at all, and she has no way to replenish her mobile phone.

"You can't use magic to charge your phone, you can only use this charging cable and a matching interface."

Lu Cheng pulled out the plug and showed Charlotte the connector on the plug, and the clever groundhog lady immediately understood something terrifying...

"Then what will I do when I leave this camp... Charge? Charlotte's voice trembled and she asked.

"The answer is that there is no way to charge it, and if you rashly use some lightning magic to inject it from the interface, the result is only one... That's broken. Lu Cheng told Charlotte a brutal truth.

Charging a mobile phone is a very cheap thing on earth, after all, there will be plugs and terminals everywhere, but this world is different...

Charlotte may have the phone, but if she wants to charge it, this is the only camp in the world that can do it.

Scarcity is expensive, but the most terrible thing is monopoly!

"Anti... You're not going to let me go right now anyway. Charlotte realized the seriousness of the matter, as if to convince herself, she took the phone from Lu Cheng's hand, and looked at the slowly rising battery on it, "I don't need to worry about this now. ”

"It looks like the Secret Law Society has sent someone to pick you up."

Lu Cheng smiled and said that Charlotte had heard what should have jumped for joy a day earlier.

"You're lying to me again?" Charlotte was reluctant to believe Lucheng's words.

"When have I lied to you, if you don't want to see them." Lu Cheng was sure that the two members of the Esoteric Order had come for Charlotte.

"Of course I want to."

Charlotte jumped off the desk directly with her mobile phone, but the charging cable of the mobile phone couldn't support such a long distance at all.

At the moment Charlotte jumped, the plug fell off directly, and the battery displayed on Charlotte's phone also jumped back from three percent to two percent.

"I'm going to run out of energy again!"

Charlotte looked at the battery display in the upper right corner of her phone, which had turned red, and she knew what terrible things would happen when the number on it dropped to zero.

"You can leave your phone here to charge it first, and then come back to get it when you have negotiated with those two members of the Mystic Society."

Lucheng has shown great generosity, and if the rabbits have enough energy, the resources mined in this world are as few as dust compared to the resources used by this groundhog.

"And what happens after I go back to the secret puja?"

Charlotte asked a question that she could figure out herself, but she still expected Lu Cheng to give a different answer.

"I'm going to think..."Lu Cheng summoned a small portal on the ground, reached into it, and took out a 20,000 mAh power bank in his home, "This is our mobile power supply, you only need to plug this section of the interface here, and the other end of the interface is inserted under the mobile phone." ”

Lu Cheng made a simple demonstration, Charlotte saw that the battery display of her mobile phone lit up green again, and she was so excited that she wanted to stretch out her little short hand to take the power bank in Lu Cheng's hand.

But Lu Cheng gently raised his hand and lifted the power bank into the air, and Charlotte couldn't touch the power bank in Lu Cheng's hand no matter how she stood on tiptoe.

"It's not free, Miss Charlotte." Lu Cheng said.

"You... Want what to exchange? Charlotte asked.

"I haven't decided yet, why don't you meet your two companions before making a decision?"

Lu Cheng was very interested in the knowledge of the Esoteric Ritual of Gmansis, but the magic items they carried with them were what Lu Cheng was most interested in, especially the reason why the two spellcasters were able to become invisible.

Stealth... This is a field where technology on Earth is still breaking through, but this world has done it with magic!

How much value stealth in the real sense of the word has in terms of strategy, Lu Cheng feels that there is no need to make too many explanations.
