Outside Billy City, whether it is the forest or the grassland, everything is filled with a dead black atmosphere. Many plants have begun to decay and wither. Even in the sunlight, they give people a lifeless feeling. All living animals and insects have left here, leaving only some monsters of various sizes. "Obviously, the impact of the demonized barrier not only stays inside the barrier, but also outside the barrier will be affected by a certain degree of radiation pollution. Under the sun, Oz dropped some pollution sources on the stone. The stone that came into contact with the pollution source quickly turned from gray to black, but before the pollution source spread to the entire stone, the sunlight had already passed through the treetops and hit the pollution source. The source of pollution turned into a burst of black smoke under the sunlight and dissipated in the air, leaving only black traces on the stone, proving that everything that happened before was not an illusion. "It should be said that it is as expected?" Oz observed the contaminated parts of the stone. Under the sun, the contaminated area looks like a scar and feels no different from an ordinary stone when touched by hand. "The amount you used is too small, Lord Demon King." Mona lay lazily on Oz's shoulder, "Such a small amount of pollution source is not enough to pollute the environment." "You guy, since you don't want to walk, Why are you still following me?" Oz glanced at the white creature on his shoulder. "As the Demon King's assistant, how can you leave the Demon King so easily?" "Then you should come down and leave!" "Demon King, can you bear to let me, with my little arms and legs, follow you and eat dust? "?" Mona said pitifully. "Forget it. Let's continue on the road. Find some living ordinary animals." Oz looked up at the sky. The bright sunshine looked a bit dazzling. In order to find suitable experimental animals. Oz ran ten kilometers away with Mona and finally caught some small animals. After conducting experiments on living organisms. Oz found that the infection effect of the contaminated source was as good as expected, but the lethality was also worse than originally expected. "It has extremely strong penetrating properties and can destroy the magic resistance of living things, but it will not cause death directly!" Oz flew in the air, watching a wild boar running around in the forest like a madman, from time to time He will also hit trees or rocks with his head. The wild boar was contaminated by Oz dripping a few drops of it. Although the source of pollution has been purified by sunlight, the scars remaining on the wild boar still exist! I saw that a large piece of skin on the wild boar's back was completely necrotic. And turned into a dark substance similar to a monster. "Although it will not cause death directly, it will completely transform the creature into a monster" Oz took out his notebook and recorded, "It is really more dangerous than originally expected." "Master Demon King" "What's the point of recording this?" Mona asked, lying on Oz's shoulder. "Isn't it natural to measure unknown magical materials through various means?" Oz wrote in his notebook, "I am still a magician no matter what." In a sense. Pollution source is also a very powerful magic material, although it is currently unclear what other uses this magic material has besides being used as poison. "The magician's thirst for knowledge?" Mona's mood was a little low, "This kind of thing. It doesn't seem to match the devil." "Don't you often say that the devil should be loyal to his wife?" Oz will The technical skills were put away, "I am completely loyal to my thirst for knowledge now." "Well" Mona looked at the wild boar running in pain below, "If it is just about 'watching the experimental subject suffer'. It is very consistent with the Demon King. "Oz looked blankly at the crazy wild boar in the forest below, and suddenly had no desire to continue experimenting on it. at this time. Suddenly there was a noisy orc language in the forest! "Ossa!" "Damn it! What happened to this wild boar!?" "No! This wild boar is completely targeting us!" "Damn it! It's all this pig. We have been discovered by that magician. !¡±¡ Oz stared down. His eyes narrowed: "Orc?" In the forest, an orc who was originally hiding in the bushes was knocked out of his hiding place by a crazy wild boar. This unexpected situation not only exposed the hiding orc, but also several other orcs. There are not many orcs, only about ten of them. They are all fanged orcs with simple equipment. They seem to be just ordinary orc soldiers. Seeing this group of people suddenly appearOrc, Oz slowly continued to rise a little higher, and then began to prepare magic calmly. "No! The magician started to cast a spell!" "Don't worry about that pig, everyone flees separately!" The orc captain roared, and all the orcs fled in all directions. Due to the language barrier, Oz finally noticed that the orcs were preparing to escape until the orcs had begun to flee. After realizing this, Oz did not hesitate to throw the half-prepared magic in his hand at the orc who looked like the captain! "Wind blades dance wildly!" Dozens of wind blades tore the orc captain and another orc who was closer to pieces into pieces. During this delay, the other orcs had already scattered and fled. "They all ran away, Lord Demon King." Mona looked disappointed. Oz glanced at the fleeing orcs, and did not continue to pursue them. Instead, he used his mental power to sense the surrounding situation. After confirming that there was no ambush, Oz slowly descended from the sky. "Lord Demon King, aren't we chasing those escaped rats?" "It's pointless to catch up anyway." Oz walked to the corpses of the orc warriors, ready to start extracting their souls. The substance glowing with a faint magical light was extracted from the corpse by Oz, forming a crystal-like thing in Oz's hand. Oz then forcibly invaded the souls in his hands and checked their memories. "Sure enough, these orcs are scouts. In addition to them, there are many other orc scout teams nearby." Oz's mental power retreated from his soul. "Lord Demon King, what are we going to do next?" Mona raised her head and asked, "Are we going to clear out the orc scouts nearby?" "Just leave this kind of thing to the monsters to deal with." Oz looked at him angrily. He glanced at Mona and said, "What do you think the existence of those monsters is for?" "But if the monsters are allowed to run around, they may not come back after leaving By the way!" Mona knocked. He shook his head and said cutely, "I'm very sorry, Lord Demon King, Mona, I forgot about those beast-eared girls!" Oz: "Wait until night and let those beast-eared girls take the monsters and go out to clear the city. The orc spies nearby can also help them improve their levels. " "Yes! Lord Demon King, I'll make arrangements right now." Oz thought for a moment, "I'd better go back to the demon world. I want to see how you plan to make arrangements." Oz is very experienced in Mona's unreliability, so Oz plans to see what Mona will do - and also go with those beast-eared girls. Let's get acquainted. Hearing Oz's words, Mona was a little surprised: "Huh? Lord Demon King, are you ready to go back now?" "Go back." Oz patted the notebook in his bag, "Anyway, I have obtained the necessary information. , I will study the rest later." "Master Demon King, don't you plan to continue to appreciate the expressions of pain that other creatures show when they are tortured?" "Please don't talk about others like a sadist! "Oz couldn't help but complain. "Demon kings are all arrogant and sadistic!" Mona raised her thumbs to Oz, "This is a universal rule in any dimension!" Oz: "I always feel like talking to you, sometimes I feel I'm so tired" "When you're tired, just ask the maids to replenish your magic power." Mona raised her thumb to Oz. "gone back¡¡"
