Seeing that Su Meng was about to push the door, two staggered lights suddenly flashed in front of Wen Cheng's eyes, like the sound of wind and sand colliding with snowy night.

"Wait a minute." Wen Cheng suddenly grabbed Su Meng.

"What's wrong, Wen Cheng?"

"Su Meng, I always feel that there is less and less time." He said.

"You mean?" Su Meng put his little hand in front of his mouth and thought.

"I want to focus more on the direction of the enemy than on learning props."

"Well, Wen Cheng," Su Meng nodded, "I also planned to do so, but I don't know much about the specific battle situation, so I'll leave it to you." She hesitated for a moment and added, "Still, leave it to me at first, don't worry."

Wen Cheng understood and pushed the door open.

The dazzling rows of display shelves display all kinds of objects, including white ceramic balls, unedged two-handed swords, palm-sized discs, colorful test tubes and glass bottles and jars, stacked in a messy row, as if squeezed into an old grocery store, and an uncomfortable pungent smell in the air.

In the corner sat an old man in a white robe, with a thin face and a wrinkled face, who wore reading glasses and stood motionless in one corner, holding a glowing pen in his hand, gently carving on a pure white porcelain plate.

"That ......," Su Meng said tentatively.

"Ahem." The old man responded, and after more than ten seconds, he put down the porcelain plate and raised his head.

The old man's hair was simply tied up, and his beard was gray, and Wen Cheng realized that the old man was wearing a coarse cotton robe on his right side.

"Is there something wrong?" The old man frowned impatiently.

"Teacher Mozi, I'm Su Meng." Su Meng pinned his little hand behind him and leaned over to let out a sweet smile.

"It turned out to be Xiaomeng," the old man took off his reading glasses, and suddenly stood up with a smile, "Welcome, welcome, what kind of snacks will you bring to the contemptible this time."

"I'm sorry, Mr. Mozi, it's urgent, I didn't have time to bring snacks this time, but I brought you a student." Su Meng smiled awkwardly and stepped aside.

Mozi? Teacher? Wen Cheng took two jerky steps forward.

"Hello Mr. Mozi...... My name is Gu Wencheng......

"Contemptible people don't accept apprentices, let's go." The old man cooled down and waved his hand.

"Why doesn't the teacher take in the apprentices?" Su Meng made a warm voice.

"Hey," the old man sighed, "Now that magic is in short supply, many students in the Craftsman Class have been poached by the Mage Academy, and now there are only four of us Heroic Spirit Teachers left," he paused and dropped the corners of his helpless eyes, "It seems that the day when the four of us will be recovered is not far off."

"Teacher Mozi," Wen Cheng said calmly, "May I ask who are the four Heroic Spirits?"

"In addition to the contemptible," the old man snapped his fingers, "There are also friends who lose the class, and the other two are Leonardo da Vinci and Tesla, because it is a shift system, Da Vinci and Tesla are off today, and the public loss class goes out to buy mahjong."

"Anyway, I don't have the heart to teach anyone, so let's go." The old man waved.

What kind of heroic combination is this, but the more times like this, the more you have to be dead-faced, right?

"Teacher Mozi, actually, ......," Wen Cheng plucked up his courage and said, "I didn't intend to be your apprentice."

"What did you say?!! The old man's white hair jumped.

"That's right," Wen Cheng said, "I'm here to find a solution to the robot dog case."

"What dog?"

"Mechanical dogs," Wen Cheng added, looking at the old man, "Right now, the mechanical dogs in Qiantang City are killing people wantonly, and thousands of people have died in just a few days......

"Wait," the old man's eyes suddenly lit up, and he spun around, "Go on."

"Teacher Mozi," Wen Cheng said, "Although I don't know much about you, I know a little bit about the truth of love and non-aggression, and there are still many children who have been killed at the moment, and it is because of the urgency of the matter that I will come to you for advice."

The old man's eyes softened, and he looked at the young man silently.

"Teacher Mozi, I didn't come here with any other intentions, just hoping to find some tools to restrain the mechanical dogs, so that I could go back and save those children." After saying this, Wen Cheng breathed a sigh of relief.

"Tell me, what do you want?" The old man said slowly.

Yoo Jin has never been traumatized, so there is no need for bandages or anything, and in comparison, the harmony inside the body is important.

"Actually, I want a lot, like the Tao of healing?" The boy added, "I guess the treatment is the optical system, my circuit is just right for the optical system......

"Healing?" The old man opened his mouth wide, "There are no healing items here, do you think this is the world of blood bars?"

Wen Cheng was dumbfounded.

"If you're talking about speeding up cell recovery," the old man smiled meaningfully, "yes, yes, but it's a big device, I'm afraid you won't be able to move it."

Wen Cheng sighed.

"Mass and energy are conserved, and even magic must follow the principle of equivalent exchange." The old man said solemnly, he hesitated for a moment, then walked to the corner and took out a monocle, "Although this can't be treated, it can monitor vital signs and the state of the magician's circuit, and it's almost dusty here, so why don't you take it."

"Thank you, teacher!" Wen Cheng happily took it.

It stands to reason that such a gift is well deserved, but this glasses don't seem to solve the fundamental problem, Wen Cheng hesitated.

"Didn't you say you wanted a lot?" The old man looked at him and said solemnly, "Since you're here to save people, don't scruple about it."

"Yes!" Wen Cheng nodded, "In addition, in addition to the light system, I also adapted to the dark system, have you ever swallowed the enemy into ......the darkness?"

"You mean the Sea of Dirac?" The old man frowned and said.

"Sort of, if it's dark, it should be the appearance of being in charge of the anti-matter world......

Although Su Meng didn't add any further, he did research a long time ago...... The probability of guessing is still very high.

"Xiao Meng," the old man looked at Su Meng, "where did you find this guy?" Why are you talking nonsense?"

"Uh...... Haha, teacher," Su Meng smiled bitterly, "That's what he thought, I'm really sorry, I haven't taught him the basic theory yet."

The old man sighed, "The secret programs are all evil methods, and the contemptible people never touch them, so think about anything else."

"In that case...... Are there any restraint circuitry props?"

"Restraint circuits? By the way, what's your name?" The old man hesitated.

"My name is Gu Wencheng."

"Contemptible people emphasize, if it's a war prop, we don't have a finished product, we have to make it ourselves, you can get the blanks and drawings and carve them yourself."

"Okay, then the blanks and drawings are good, but Mr. Mozi, I came in a hurry this time, I didn't bring a backpack, do you have a bag or anything here......

"Bags?" The old man walked in and looked at Wen Cheng like an alien.

"yes, bag...... If not, it doesn't matter, I'll go out and buy one......" Wen Cheng supported him.

"That, Wen Cheng......" Su Meng whispered, "I'm sorry, I forgot to tell you, after the props here are injected into the fusion program, they can be converted into the form of a law source and stored by your circuit......

"In other words, I can keep it in my body, right?" Wen Cheng's face was joyful.

The principle is unknown, but the problem is easier to deal with, and if I could, I would like to move this house away.

"Yes," Su Meng smiled, "but there is a capacity limit, and you can store ten units according to your circuit."

"What do you mean by 10 units?"

"If that's the standard." Su Meng pointed to a white porcelain ball on the shelf, "It's exactly ten."

Wen Chengtan breathed a sigh of relief.

"Sure enough, I don't understand anything, Wen Cheng." The old man smiled meaningfully.

"Uh...... Hehe, the teacher smiled."

"Oh yes, what did you just say, restraint circuit?" The old man asked.

"Hmm," Wen Cheng nodded.

"Wait, I'll ask Tesla." The old man brushed up his beard, walked back to his workbench, and picked up the telephone on the table.
