However, Xiaohui soon discovers that the iron-eating beast does not eat bamboo, but likes to gnaw on various metal ores and digest the ore with the acid it secretes.

Xiaohui carefully discovered that the iron-eating beast secreted a variety of acids, which could correspond to the strong acids such as sulfuric acid and nitric acid on the earth, so she asked Lena to teach the iron-eating beast how to mix various acids into more powerful corrosive liquids, such as aqua regia.

Xiao Hui's memory is very messy, unsystematic, and of different shades, but Lena Fox is like a treasure, no matter whether he understands it or not, he is stuffed with the young beasts like a duck, in fact, sometimes he imparts knowledge that he doesn't understand at all, for example-light has wave-particle bidirectionality, and the total energy of matter is equal to its mass multiplied by the square of the speed of light--but the more Lena can't understand it, the more he admires Xiaohui's mother, because Xiaohui's mother-in-law actually knows the same knowledge as the book from heaven!

Lena naturally doesn't know, Xiaohui's knowledge is actually some "common sense" that she knows as a modern person in the 21st century, and if she really wants her to explain the further principles, Xiaohui will be blind immediately, not to mention anything else, just a concept of "gravity", Xiaohui can't tell a reason, just knowing that an apple woke up a guy named Newton.

Lena Fox also tried to find an apple to smash his head to see if he could smash the "gravity", but unfortunately, there is no such sweet fruit called apple in the other world, and most of the fruits are poisonous, and even open their mouths to bite people. Therefore, Lena Fox is destined not to become a Newton from another world.

Of course, Xiaohui's messy knowledge still has a certain effect, not to mention anything else, the iron-eating beast benefits a lot, and the regia water it mixes by itself, even the iron giant and Jiaolong are afraid of three points when they see it, this thing is worthy of the name of the king, and even the secret gold after refining can be corroded.

Who would have thought that an iron-eating beast that sells cuteness for a living could have such an ability to defy the sky? If it is allowed to evolve on its own, even if it evolves for hundreds or thousands of years, it will not be able to evolve such an ability.

Lena Fox raised his head to the sky, thinking of the voice and smile of Xiaohui's mother, who was right, knowledge is power!

Lena Fox turned around and yelled, "Students who don't finish their homework will be punished for copying today's text 100 times!" As for the purpose of copying textbooks, this does not need to be asked Lena, needless to say, it is one of the messy memories in Xiaohui's mind.

At this command, the iron-armored tortoise beast looked at its stubby claws and wanted to cry without tears, but the centipede beast waved its arthropods and laughed triumphantly.

Today's dungeon shows a thriving scene, to be honest, in addition to the knowledge of the earth that Xiaohui imparts to everyone, what is more important is the order she brings to all the monsters.

That's right, that's the power of order!

The birth of civilization, in addition to the inheritance of knowledge, the establishment of order is also of extraordinary importance.

Destruction, killing, and destruction cannot create civilization, and only order can provide space for civilization to grow.

Xiaohui's job is a female police officer in the police station, so she instinctively has a unique emphasis on order, as soon as all the monsters arrive in the dungeon, they will receive a thick dungeon code, which is not too big or small, and there are all regulations, so detailed that walking on the right, washing hands before and after eating, are all listed.

It is under the constraints of the code - of course, in the early stage, Bai Xiaofei, Niu Niu, Iron Giant, and Jiao Snake are indispensable to take action, so that the guys who refuse to abide by the code can learn a lesson - monsters with different personalities and different abilities can live in harmony in the dungeon.

And the long peaceful years of the dungeon have given the young monsters time to slowly learn Xiaohui's messy knowledge, and have become a new generation completely different from their parents, this new generation, no longer blindly relying on brute force and their own evolutionary instincts to survive, but know how to use knowledge to make themselves smarter and stronger.

After Lena gave the cubs a lot of class work, she began to work on her latest topic, magic.

Lena meditated on a piece of paper with many unknown symbols memorized, and the words in his mouth were recited: "Mistress Xiaohui said that if you recite a spell, you can make a broom fly, and then you can ride on it, and you can fly." Well, we have a lot of flying monsters in our dungeons, but I can't find out how the spell that makes the broom fly - the flying broom drawn by the mother of the little Hui has no wings at all, and the shape does not conform to aerodynamics - ah, this magic is so difficult! ”

In the nursery school, countless monster teachers are teaching the young beasts the knowledge of the awakening of the little master mother, just like the fox of Lena, however, the adult monsters are also busy, and they are preparing for the new evolution and upgrading competition.

The Golden Horn Unicorn King, who had just migrated to the dungeon with his clan, was also notified, and he asked one of the hummingbird beasts who had passed the order to him, "What is the Evolution Upgrade Competition?" ”

The hummingbird beast is famous for its fast flight and dexterity, its small pointed beak can pierce more than ten holes in the enemy's body in a second, because of its light body and omnidirection, so it is used as a herald of the dungeon by Xiaohui.

The hummingbird beast flapped its wings at high speed, and said in a consistently fast tone: "The evolution and upgrading competition is that adult monsters fight in the gladiatorial arena in the form of a competition, and the winner can get the other party's genes to evolve, Xiaohui said that genetic evolution and knowledge inheritance are the two magic weapons for the survival of monsters in our other world, and both legs must be hard to walk, and neither of them can be wasted." ”

As soon as the hummingbird beast finished speaking, it flapped its wings and flew away, and it had to go somewhere else to give orders.

The speed of the hummingbird beast is too fast, and there are some unique terms from the earth that Xiaohui is mixed in, and the Golden Horn Unicorn King, who has not been learning Chinese for a long time, doesn't understand it a little, and after thinking about it for a long time, he suddenly woke up - isn't this so-called evolution and upgrading competition the same as monsters fighting each other outside the dungeon? Isn't it like eating each other's genes to evolve by getting each other's genes?

I didn't expect to go to the dungeon, and I actually had to participate in the bloody and cruel battle!

The Golden Horn Unicorn King looked at the code he received as soon as he entered the dungeon, and let out a low sigh, the so-called peace in this dungeon is actually an illusion, as long as it involves evolution, it will also kill and devour!

However, unicorns are very proud creatures, and the Golden Horn Unicorn King quickly cheered up and wanted to fight? Then let's fight! I used to be on the grassland, I don't know how many monsters I had defeated, and those monsters wanted to kill themselves and eat their own flesh, but in the end, they became their own meal!

The golden-horned unicorn showed the sharp teeth in its mouth, humming, there are also many strong monsters in this dungeon, but they are not so easy to admit defeat, so it depends on who is standing on whose corpse in the evolution and upgrading competition!

The two days come and go, time flies, and the Evolution and Upgrading Contest is finally here.

Early in the morning, Lena came to the Jiangnan hut early in the morning: "Lord and mother, the residents of the city are gathering for the big arena, just waiting for you to go and announce the competition. ”

Xiaohui was pushing Bai Xiaofei: "Get up quickly, for such an important matter as the Evolution and Upgrading Competition, you can't be late." ”

The flames flickered in Bai Xiaofei's eyes: "Every time I hear about the Evolution and Upgrading Competition, for some reason, I feel a little uncomfortable in my heart, it seems that on the earth, I have experienced a similar competition, and I also met a person because of this, and that person finally died in my arms." ”

Xiaohui asked, "Is it a man or a woman who died in your arms?" Don't you still remember that? ”

Bai Xiaofei coughed: "No, I didn't think about it." In fact, he lied, and Bai Xiaofei clearly floated a toned figure in his heart, and even her name: Ziyuan. However, what is the relationship between himself and this girl named Ziguan, Bai Xiaofei really doesn't know anything.

However, just a beautiful girl dying in his arms is already a headache for Bai Xiaofei, isn't what he loves, Xiaohui? Could it be that he is a big carrot?

Xiaohui dragged Bai Xiaofei up: "Let's go, let's go, evolution is a matter of life and death for the monsters in the dungeon, in this terrible world, continuous genetic fusion, continuous evolution, is the best survival method after hundreds of millions of years of evolution in nature, survival of the fittest." Our knowledge can only help them in a certain way, and evolution is fundamental to this world. ”

Bai Xiaofei had to stand up, and let Xiaohui put armor on him - in fact, no armor could compare to Bai Xiaofei's own platinum body, but Xiaohui insisted that he wear it, saying that it was more manly-

The appearance of this set of armor is completely different from the armor evolved by the monsters of this other world, but the armor of General Gu Yanhuang, which is composed of an armor body, armor sleeves and armor skirt, and a beast-faced heart armor on the chest, and a few flags on the back. In the end, Xiao Hui held it in both hands and put a helmet on top of Bai Xiaofei with a small flagpole like a lightning rod on the top of the spire.

Bai Xiaofei muttered: "You can't fight at all when you wear this thing, it's like a singer." Having said that, Bai Xiaofei still strode out the door.

As soon as Lena saw Bai Xiaofei wearing armor, he immediately saluted: "Hello General Fei." ”

Bai Xiaofei raised his hand and saluted back: "Serve the people." ”

Outside the door, the iron giant and the snake were already waiting, Bai Xiaofei waited for Xiaohui to come out with Niuniu in his arms, and then sat on the back of the snake and headed towards the arena.

The so-called big arena is actually the ranch of the dungeon, because the field here is wide enough to accommodate the more than 100,000 monster residents of the dungeon, and at this moment, the big arena is already crowded with monsters who come to compete, residents who watch the game, and young beasts who come to learn.
