"Hey, Hercules hasn't seen you in a long time!" Gusas waved his palm at Hercules in greeting, his expression radiant, his cheeks puffed out, and the corners of his mouth bent to show the joy of being reunited after the catastrophe.

"Sure enough, it's Gusas!" Hercules muttered softly.

However, Hercules only replied very blandly: "Hello, Your Excellency Archon! After that, I didn't show too much enthusiasm.

Seeing Hercules so cold, Gu Sas squinted his eyes, and turned to Tianxuan to show a bright smile: "Ah! Tianxuan, you haven't seen you for a long time! I didn't expect you to go out with the troops, which was beyond my expectations! ”

"It's not a big deal!" Tianxuan scratched the back of his head embarrassedly, pursed his lips and said, "I've experienced too many things, I have to make myself stronger!" ”

Gu Sath laughed a few times, applauded a few times, and praised Tianxuan.

"Oh yes, Mr. Gusas, why did you suddenly come out of the city?" Tianxuan asked with a wink.

Gusas cleared his throat and deliberately raised his voice and said, "I have been lurking in the city waiting for an opportunity, and I have been waiting for an opportunity after Brenthal's troops attacked the city. At this point, Gusas raised his arms and shook them as he continued, "Just as I saw you start the siege of the city, I took the few surviving men with me to take down all the poisoned people who defended the city. ”

"Oh, that's it! It's not easy for you! Tianxuan took a long breath and bowed his head slightly, exclaiming for Gu Sas's perseverance.

Gusas closed his eyes, turned his gaze to Hercules, and said, "No, as soon as I saw you coming, I hurried out of the city to greet you." ”

Gusas's words were tantamount to telling Hercules that he had put a hot face on his cold ass. In front of everyone, it is equivalent to slapping Hercules in the face.

"Hungry ......" Hercules was speechless for a while, and he had to find a step down for this situation, so he walked up to Gusas with a smile on his face, took his hand, turned to everyone and said: "Lanmian City has been liberated, and Mr. Gusas has contributed a lot to avoiding a senseless bloodshed!" ”

"Oh, woo!" After saying that, the whole army boiled and let out a carnival laugh.

Next, Hercules entered the city directly under the leadership of Gusas and quickly interspersed to the war zone on the other side. Due to the internal and external attacks, the remaining poisoned people collapsed almost at the touch of a button, and all of them were arrested and sent for treatment without a few tosses.

Hercules then ordered his men to open the gates and welcome Brenthal's troops into the city. In this way, the two troops successfully met in Lanmian City. The rebellion in Lanmian City came to an end.

Next, Hercules led his men to search for the remaining poisoners throughout the city, while Black and Gusas were in charge of greeting Brentel's envoys in the city lord's hall, and Tianxuan followed him to the city lord's hall.

Returning to the hall of Lanmian City, Tianxuan suddenly closed his eyes and sighed again in the process of walking, and there was an indescribable feeling in his heart.

"What's wrong? Revisiting the old place, how much do you feel? Gu Sas poked his head into Tianxuan and said with a smile.

"Hungry, hungry, how can you say it! Joy and sadness, I can't talk about it, but there is a little bit of nostalgia, think about how high-spirited the original Yuwenquan City Lord was, but now he has become a cold corpse. Tianxuan shook his head gently as he spoke.

"Things are in the past, we have to look to the future, don't dwell on the past, only make the future better! You say, don't you? "Gusas enlightened Tianxuan.

"Hmm!" Tianxuan nodded knowingly.

When everyone reached the hall of the city lord, Gusas and Black ordered the troops to stand in two straight rows like a guard of honor. Then, after a few minutes, a man in white underwear, a gray cape, and a gray armband walked in.

The man in white walked in with his head held high under the gaze of everyone. I saw that this person was very popular, with triangular eyebrows, drooping eyes, and the pointed bridge of the nose, which made him even more courageous.

Tianxuan saw that this person had a great background, and he was busy whispering to Gu Sas: "Mr. Gu Sas, this person who walked in is a big man!" ”

Gusas stood there motionless, only the corners of his mouth opened slightly, and he said softly: "Yes, he is the chief consul of Brentel - Minos, and he is the largest of all Mayan consuls." ”

"Oh!" Tianxuan shook his head up and down, looking quite surprised. But after understanding, he stopped talking and stood carefully to observe.

I saw Minos go straight to the stage and sit in the place where Yu Wenquan once sit, and everyone's eyes were focused on him at this moment.

"Everyone, you have worked hard to quell the riot in Lanmian City! I would like to express my sincere gratitude to all of you! Minos's voice resounded through the hall. After thanking him, he looked down at Gusas and said, "Archon Gusas, Lanmian City has now been pacified, how is the imaging recording system now?" ”

"Only a small part of the damage was damaged, and I was able to fully resume work in three hours by sending someone to repair it later." Gusas replied to Minos with his hands clenched.

"Very good! After the meeting, you can get started! Minos said.

"Order!" Gusas replied solemnly.

After asking about the situation on the side of Gusas, Minos turned to Blake and said, "Captain Blake, now you have full authority to take over the defense of Laman City. Later, the whole city is cordoned off as fast as possible, and no one is allowed to enter or leave at will. ”

"Order!" Blake replied solemnly.

"Well, Brenthal's engineers will arrive in two days to help with the rebuilding of Laman City. Let's do your job and adjourn the meeting! Minos went to the Hall of the Archons with Gusas after a brief meeting. Tianxuan, at the invitation of Gu Sas, also went with him.

After arriving at the Consul's Hall, Gusas led his men to repair the system for 3 hours, and finally repaired the imaging recording system.

"That's it?" Tianxuan asked.

Gusas shook his head and said with a smile: "This is just the beginning, and the next is the important work." ”

"What's important work?" Tianxuan frowned and blinked, feeling puzzled.

"Just follow along!" Gu Sas deliberately raised his head and said a little mysteriously.

Then, Tianxuan followed Gu Sass and they drove the water and land vanguard all the way along the city wall of Lanmian City, and every time they came to the edge of a broken city wall, Gu Sas had to go down with his subordinates to extract some red granular objects on the city wall.

For this red granular object, it spreads almost in a horizontal line all over the city wall, and the red line is as long as the city wall is. This is not the point, what happened next made Tianxuan completely shocked.

"Tianxuan, what are you doing in a daze? We've got you covered, it's time to move on to the next one! Gu Sas looked at Tianxuan and stared at the city wall in a daze, and urged.

Only then did Tianxuan come to his senses and hurriedly walked on the water and land pioneers.

"What did you look at just now, so fascinating?" I asked curiously.

"Hungry, hungry!" Tianxuan hesitated for a moment, rolled his eyes upward, and recalled the situation just now, "Mr. Gusas, I see the red particles on the city wall and feel very familiar, as if I have seen it somewhere. ”

"Oh! Is it? Gusas touched his chin and smiled, "Then think about it, what does it look like?" ”

Tianxuan touched his head, thought for a few seconds, and said, "It's like rust." After saying that, he looked at Gusas blankly.

"You're right, it's rust, so to speak!" Gusas said.

"Is it really rust?" Tianxuan's eyes widened, and he was shocked.

Gu Saas laughed a few times, then pointed to the red particles and told Tianxuan: "To be exact, it's ferric oxide." ”

"Ferric oxide?" Tianxuan's mouth opened wide and interjected, "Ferric oxide, I remember that it seems to be used for medicine and paint on our ground!" It's no wonder that the city walls are painted with ferric oxide, but I don't think the decoration style is very good. ”

Gusas shook his finger and said, "You still don't know much about ferric oxide!" ”

Speaking of this, Gusas deliberately tuned his voice and said: "Ferric oxide can also be used in magnetic raw materials such as electronic industry, communications, imaging systems, and line output transformers, switching power supplies, and technologies such as high U and high UQ. ”

Tianxuan suddenly realized: "Oh, I see! In this way, the red band formed by ferric oxide here is connected to the imaging system in the Archon Hall! ”

Gusas nodded and replied, "That's right! You're not wrong about that! ”

However, Tianxuan still couldn't understand the connection, and still frowned and asked, "But I can't think of it, what is the connection between them?" It's hard to see a film on the entire city wall, and I don't think it's realistic! ”

Gu Sath laughed: "Of course it's impossible to show a movie on the entire city wall!" ”

"What's that for?" Tianxuan continued to ask.

Gusas snapped his fingers, and then told Tianxuan, "Say so! Ferric oxide has two different configurations, α and γ, the α form is paramagnetic while the γ form is ferromagnetic. Hematite that exists in nature is the α type. If ferric nitrate or ferric oxalate is heated, α-type ferric oxide can be obtained. Oxidation of ferric tetroxide yields γ form of ferric oxide. γ ferric oxide is converted into α above 673K. Ferric oxide can be used as a red pigment, polishing powder, and as a catalyst for certain reactions. ”

"α and γ?" Tianxuan's eyes widened, and he said, "I'm really unheard of!" What does this have to do with imaging systems? ”

"The photosensitive materials they use for imaging!" As he spoke, Gusas pointed to the red particles and said, "On the substrate of acetate or vinyl chloride, the γ-Fe2O3 can be coated with vinyl chloride-vinyl acetate copolymer or styrene-butadiene copolymer as a binder, and the image can be recorded." ”

"Recording images?" Tianxuan was puzzled.

"Yes, it's to record everything that happens around you, everything that everyone does in the city every day." Gusas replied.

"And there is no tracking shooting, how is this possible?" Tianxuan didn't believe it.

Gu Sas laughed and said, "No matter who or anything, it will leave traces, don't you have an animal on the ground called a dog?" And the snake knows? As long as it doesn't rain, they can catch the traces left by the creatures even after many days. ”

"That being said, I understand that, but I still can't accept such a thing for a while?" Tianxuan shook his head slightly, indicating that it would take some time to accept this fact.

"It's okay, I'll show you around later, and you'll understand! When you see it with your own eyes, you will have a deep understanding of this common sense. Gusas said calmly.

"Oh, could it be that Minos blockaded the entire city of Lanmian just so that these red particles of the city wall would not be destroyed?" Tianxuan asked with a wide open eye.

"That's true!" Gusas nodded in reply.

"He wants to spy on everyone? What a pervert! Speaking of this, Tianxuan kept pouting and shaking his head.

"Don't talk nonsense!" Gu Sas interrupted Tianxuan's words and said, "Who would be so perverted! We all have normal legal procedures, and we don't give them to private people to watch at will, even the top leaders of the Maya are not qualified to do so. ”

"Then I don't understand, what is the purpose of recording what everyone does every day?" Tianxuan tilted his head and looked at Gu Sas, his eyes straight waiting for the answer.

Gusas stretched out his right hand, swung it up and down, and said, "All right, all right, I'll tell you!" It's all for the sake of investigating the case. ”

"Investigating the case?" Tianxuan finally came to his senses at this time, and exclaimed: "Oh, I understand, it's to get evidence, right!" ”

"That's what happened!" Gu Sasi nodded helplessly towards Tianxuan: "You finally understand, everything is for the purpose of investigation and evidence collection, and everything is decided by evidence." ”

"If you say that, as long as you commit a crime, it will definitely be recorded, so no matter what he does, he can't run away!" Tianxuan asked himself.

"Indeed, none of the criminals should try to run!" Gu Sas took Tianxuan's words and added, "Therefore, Minos blocked the entire Lanmian City, and anyone can come and go at will, just to liquidate these criminals!" Now you understand that he is not a pervert! ”

"Got it, got it!" Tianxuan nodded embarrassedly. He then followed the Gustas to collect the red particles. Because he understood the ins and outs of the matter, Tianxuan was extremely cheerful, and he was also energetic and busy when he worked.
