Two more trucks drove into the space island, one carrying 20 Baihua cows and 10 cattle. Saying that cows make people think that the cows with big white flowers are all females, but in fact, the cows with big white flowers have males and females, and the males are killed in addition to breeding, and most of the cows are left to produce milk. The other truck was carrying a large tin can. Remove the leaking liquid from the wreckage of the machinery placed in the beachwear. There was also an iron workbench for Helen and the blacksmith to use for their work. Mobilize all the villagers to put on protective clothing and start cleaning up the wreckage of the machine on the beach. The protective clothing was bought from the manufacturer who burned the garbage. There should be no radiation on the beach, but if you have to dismantle the machine and dump the waste liquid, the refining of metals will inevitably come into contact with radiation, and Helen will wear this even more if she wants to use those chemical liquids for experiments.

It takes a busy day to clean the beach, and the scrap metal is left alone in one place and can be picked up at any time when the blacksmith is in use. All the chemical liquid inside the machine is poured into a large iron can, and the lid is placed at the foot of the snow-capped mountain. As the night deepened, everyone entered the tavern in the village and prepared to eat and drink, and the tavern and restaurant in the village were one. Actually, people can go to the 'food court' to eat, but there are waitresses and chefs in the tavern who don't need to do it themselves. Everyone is tired and waiting to eat ready-made! Lu Feiyu took out a bunch of books on physics, architecture, pharmacy, smelting, science textbooks from elementary school to high school, etc., and handed them to the blacksmith, architect, and Helen. 'Do you understand?' The three of them said that they could understand the sentence, but they did not understand the meaning. 'It's okay, you guys take your time and figure it out. These are all relevant skill books for your profession, study them well! ’

Halfway through the meal, the sound of a conch horn came from the shore. 'This is the signal, the big squid is coming!' It's the 'sea monster' that the mermaid princess said. Lu Feiyu went down to the island by himself, and it was better for the villagers to stay on the island if they couldn't help. On the coast, he saw the 'three beauties' who were anxiously waiting for him, holding electricity, fire, ice sword, fire shield, ice shield, and dragon shield in their hands. Each person was given two bottles of amplification potions, and two barrels of 'accelerated gasoline' were poured into the submarine and rushed to the battlefield with Sanmei. Now Lu Feiyu's wisdom is not low, and his comprehension has also been enhanced, and he can perfectly control the car after a period of practice. What's more, it's much safer to fight in a submarine than to face that monster directly.

Dive to a depth of 200 meters and the battle has begun. The merfolk warrior held a trident in his hand and surrounded the squid, dodging and waving tentacles. On the periphery are some merfolk mages that unleash ranged magic such as ice picks or water bombs. Unexpectedly, the mermaid could also spell, which made Lu Feiyu increase his knowledge. What a pity! The encirclement was broken again and again, and the casualties of the mermaid warriors became more and more serious. The body like a double-decker bus carried the lives of a dozen mermaid warriors with each impact, but the attacks on it were painless. It's a really one-size-fits-all battle. Sanmei raised her shield and swung her sword to join the battle, and Lu Feiyu also drove the submarine to rush up. If this 'Sanmei' Tai Chi Sword was really not practiced in vain, he accelerated the taking of the amplification potion, and it was easy to walk between the tentacles wielded by the big squid, and after a while, the tentacles were cut off in half by the combined attack of the three of them. Lu Feiyu also took the lead, machine gun fire, missile launch. The big squid retreated again and again, and the pieces of his flesh splashed from the ammunition, although it was not a serious injury, but the big squid obviously felt threatened under the continuous attack.

It turned around and rushed towards the submarine, but now Lu Feiyu's submarine was filled with 'acceleration gasoline', and the agility was not something that the squid could hit if it wanted to. Easily bypass attacks and take down one of the squid's wrists and feet when it hits. The big squid was even more angry, and chased after Lu Feiyu. And the merfolk behind it took the opportunity to sneak up behind it. There were more and more wounds on the squid's body, and blue blood flowed in the sea. The squid, who realized that he had suffered a big loss, changed his strategy and began to adjust his head to pinch the soft-footed shrimp. So the merfolk began to be unlucky again, and the number of casualties continued to increase. After all, it's a merfolk alliance that can't let things continue. Lu Feiyu attacked and harassed behind the squid again, and adopted the 'kite flying' style of play. In fact, Lu Feiyu felt that the term 'flying a kite' was inappropriate, it should be called 'fishing', slowly consuming the other party through distance containment, more like pulling a fishing line. The enemy can give up the fight, and the fish can break free from the line. And the kite is dead, you can drag it as much as you want, and it won't end up. After all, I am a Gemini, not a Virgo, and I care too much about the details of this science.

Just when Lu Feiyu thought that the squid boss in front of him would be consumed by them sooner or later, a sudden mutation occurred! Meihong was entangled by a tentacle, and the tentacle curled closer and closer, and Meihong's sword fell to the ground. Mei Lu and Mei Jin swam over to rescue, but Lu Feiyu saw that the time limit of the amplification potion had passed! They can't see it. In a hurry, I slapped the 'self-destruct' button on the operating console, and the submarine flew like a missile and crashed into the tentacles that grabbed this beautiful one, 'bang'! The tentacle was directly blown off, and Meijin and Meilu swam up to hug Meihong. How can the big squid be willing! The body rushed towards it. 'This and that, save one and take two. Lu Feiyu hurriedly took out the L gun to rescue! As soon as he fired two shots, the big squid couldn't stand it and roared! Although the wound is less than a small hole, the laser is a penetrating burn! 'Take advantage of your illness to kill you!' Shooting wildly at the squid's head, the squid's body immediately turned into a plug with open holes, and the big eye like a western plate was blinded, and the bulging blue blood bubbled out. The squid wailed and retreated, and Lu Feiyu followed closely. During this time, two of the tentacles of the large squid were interrupted.

Victory was just around the corner, and everyone's attacks became more violent, but Lu Feiyu, who was pursuing, was bounced back with a 'bang'! It's a spatial shield! 'I want to chase~ but I can't do anything. After explaining the situation to Sanmei, they recalled the mermaid troops, after all, it was impossible for them to defeat the sea monster without Lu Feiyu's assistance. In the end, everyone could only withdraw their troops in frustration, Lu Feiyu picked up the big tentacles of the four squid, and said viciously, "I'll eat squid whiskers with spicy sauce tonight!" ’

Entering the cave, the mermaid princess in the underground lake anxiously swam ashore to inquire about the battle, and Lu Feiyu told her. Alyssa sighed, "Alas, it would be nice if we could learn more powerful magic, but unfortunately my mana is not enough, if I have enough mana, I will launch the 'Ten Thousand Miles of Ice' to cover the sea area of my home with an ice wall and isolate the sea area from the outside world, so that we can also ensure that we mermaids!" ’

'What? If the mana is insufficient, can the magic scroll be used? Oh, you said it would be okay if you could learn powerful magic?' Lu Feiyu asked.

Alyssa nodded, and grabbed Lu Feiyu's hands excitedly, "Do you have a magic scroll?" ’

'You can get it' Lu Feiyu took out the 'Book of Magic', 'Look at this, can you understand it?' ’

'Great! Yes? This is the 'Book of Magic'! Alyssa covered her mouth with her hands in disbelief 'you, how did you ever it'. ’

That's a long story, can you understand it, can it make you learn spells? ’

'Yes, of course. You, will you give it to me? Alyssa was already overwhelmed with excitement.

Of course you can, but I have the conditions! ’

Alyssa recovered from her excitement, yes! There is no such thing as a free lunch. What does the lord want? What can she give? Wealth? There are a lot of people on the other side, so what else does she have? 'What, what conditions?' Alyssa looked up at Lu Feiyu again, and randomly bowed her head and said, "As long as you are willing to give me the Book of Magic, I will promise you!" ’

It sounds so awkward: 'What can you give me, I have all the material wealth and can even help you.' Others~ You can't look at 'use' in this body, what can I expect from you! Lu Feiyu said depressedly in his heart. 'I just ask you to always be friendly with us humans, and not to wreck each other!' This book of magic contains a lot of powerful magic, and I don't want you merfolk to threaten my home and villagers when they become strong. It doesn't matter if you're a wicked person, but my villagers are kind, and if you can't guarantee friendly coexistence with the villagers of my village, I will never give you a sharp weapon like the Book of Magic, you know. ’

'Huh? That's what you're talking about? Alyssa was stunned.

'Ah, that's it. What should you be'

'Oh, oh, no, I promise you, I'll make a law that if there is a mermaid, your villagers will be executed. But if you hurt us, we'll fight back' Alyssa was a little happy at this time, but for some reason she was a little disappointed

That's it! Lu Feiyu handed the magic book to Elisa, "I'll give you the magic scroll in a few days, and then you can get that ice seal and cover this sea area!" I can help you for a while, but if I go beyond the space range, I will be blocked and bounce back, and I will be powerless at that time, and I can't help. So let's cover it up, anyway, there are enough aquatic creatures in the sea for you to eat. Besides, we still have products in our village that we can share with you. After this battle, there are only sixty or seventy mermaids left.

Alyssa nodded and began to delve into the Book of Magic.
