Those dry batteries were in the mouth of the demon cow, and they were ground by the teeth like a stone crusher, but the metal cleaning ball was extremely tough, just flattened, but it was not broken, but the demon cow didn't care about it, and swallowed it directly, its stomach and intestines were nothing, and the fist-sized iron ore could be digested, not to mention this delicious metal wire ball?

The demon bull quickly ate up the cleaning balls and dry batteries that Guo Dalu threw under the tree, knocked down the miscellaneous trees, and returned to the cave with a satisfied heart with the flashing LED lights with sharp horns.

After talking all night, after getting up the next day, Guo Dalu asked Wang Deen to beat a few birds and beasts, peeled and barbecued, and hummed an unknown song, like a rich boy who came to play.

Although Wang Deen had a belly to ask, he didn't open his mouth, he honestly served as his domestic servant, and Guo Dalu waved his hand: "Let's go, go and see that big stupid cow." ”

Wang Deen was a little expectant, I don't know what method Guo Dalu used, and he descended the demon cow silently? However, he was soon disappointed, Guo Dalu took him, secretly climbed the hill bag opposite the entrance of the demon cow cave, hid in the grass and looked at it with a telescope -- the demon cow just ran to the bottom of the cliff outside the cave to eat ore, and his whole body, not even a single hair fell out, so good that it couldn't be better.

However, Guo Dalu was in a good mood, watching the demon cow eating and chewing iron ore, and muttering in his mouth: "Eat, eat, eat, the more you eat, the better, you will die." ”

One day, two days, three days, Guo Dalu took Wang Deen, stayed outside the demon cow cave, did nothing, except for playing barbecue, that is, peeking at the movement of the demon cow with a telescope from afar, Wang Deen had already scolded in his stomach and opened the pot - is this Guo Dalu here to play or to subdue the demon?

On the fifth day, Wang Decheng was holding a telescope and watching the demon cow repeatedly hit the cliff wall to eat ore, and then hit the cliff wall to eat ore, and suddenly found that the demon cow's appetite seemed to be a little bad today, because it only ate a few mouthfuls of ore, then paused, chewed a few mouths, and spit out the iron ore ballast in its mouth.

What's going on? The demon bull swallows everything, even if it is swallowed with a sword, it will not burp.

There is really something wrong with the demon bull, it is irritable and spinning under the cliff, hitting the cliff wall with its stupid body, making a dull roar, and lying down on the bluestone for a while, but it can't lie down for a while, and then stands up again, a picture of uneasy sitting.

Wang Deen was not a fool, and immediately understood that the strange appearance of the demon cow must have been caused by Guo Dalu's means, but what did he do? Wait, could it be that the wire ball and small cylinder thrown under the tree that day were poisonous? However, the stomach of the demon cow is not afraid of all poisons in the world, what kind of poison is it, even the demon cow can be poisoned?

Watching the demon cow staggering back to the cave, Wang Deen quietly looked at Guo Dalu in fear, and asked cautiously after a while: "Master, what should we do next?"

Guo Dalu waved his hand: "Wait, I can't eat hot tofu in a hurry, let those foam blocks, plastic bags, and battery-corrosive electrolytes make a little more noise in its stomach." After that, Shi Shiran put his hands behind his back, went back to the ravine where he slept, and threw down a sentence: "Wang Deen, I want to taste bird eggs today, you go and dig out a few wild bird eggs." ”

Wild bird eggs are actually not delicious, cooked in the ashes, after the shell, a little faint fishy smell, Wang Deen respectfully held the bird eggs in front of Guo Dalu, Guo Dalu raised his hands and feet to level the demon cow that is invincible, worthy of his respect.

Wang Deen hesitated for a while before asking, "Master, did you surrender that demon bull the wire ball and small cylinder you threw down in advance?"

Guo Dalu nodded: "That's right, I wrapped foam blocks and plastic bags in the wire ball in advance, those substances are extremely difficult to dissolve, plus after the battery is broken, the graphite, ammonium chloride solution, manganese dioxide and other electrolytes inside are leaked out, the demon cow's stomach is full of iron, on the one hand, it is blocked by foam and plastic, and on the other hand, it is corroded by electrolytes on the inner wall, hehe, this is more lively than Sun Monkey drilling into the belly of Princess Iron Fan." In addition, this demon cow is a foodie, and a few days ago, his stomach was not used to swallowing a large pile of iron ore, and he blocked his appetite. To put it simply, this demon cow has eaten himself up!"

Wang Deen desperately remembered in his heart what terms such as "horse running block", "tree material", and "ground solution", and he knew that if he reported these secrets to Zou Ming, it would be a great achievement! Who has ever seen a demon cow drop without much effort?!

Guo Dalu suddenly smiled: "This knowledge is too profound for you today, these are almost the knowledge of junior high school, I have not even explained the concept of electricity in Yixue until now, wait for Wang Deen, you will slowly read more books, make up some lessons, and keep up with the teaching progress of the school, you will understand these things." ”

Wang Deen was stunned: "I'm studying, master, I'm just a slave, what do I read?"

Guo Dalu glanced at Wang Deen: "I see that when you passed by the Yixue School, you also stopped to listen carefully, you should have recognized words before, right?"

Wang Deen didn't know what he remembered, his face changed several times, and he said dryly after a while: "When I was a child, I knew a few words, but later, in order to eat a mouthful, I threw them all away." ”

Guo Dalu said: "If you have a foundation for literacy, then it will be easy to do, and I still think that after a while, I will hold a literacy class in the village, so that the villagers can also read and write." ”

Wang Deen was stunned for a while with his mouth half-open, and then he stammered: "Villagers? What books do those hillbillies read? What kind of books do they know? Do they still expect to fail the exam?"

Guo Dalu snorted: "Wang Deen, you guy, it's not good to look down on working people." Literacy, in fact, is not very difficult, my simplified characters, pinyin, can make it more convenient for the people to recognize and read, not to mention, the children I trained in Yixue are not taught in vain, they now almost have about the amount of knowledge in the third grade, let them go home as a small teacher, teach their parents to learn two or three words in one night, a year down, every household can write some simple letters by themselves, will count some simple accounts, and is no longer blind. ”

Wang Deen has seen the wit of the children of Yixue, so he said that the big girl, whether it is writing, endorsing, or doing math problems, it is all the top quack, Li Huafuzi praised her vigorously, saying that the students in the county school are not as good as her, if a woman can also take the imperial examination, then the girl will definitely be able to take the female champion back. If these children do go home and teach their parents to read, they may be able to do it. (To be continued.) )
