Liu Jingtian tried hard to recall a very valuable game "Age of Empires 2" back then...... Sure enough, there is still a shortage of farmland in a science and technology. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The 65-centimeter Great Demon King gave an order, and the dogheads began to assemble again.

They first removed all the clay bricks from the walls and floors, recreated a row of "brick holes", and then piled charcoal and baked them with fire to disinfect and sterilize. Then a large amount of sawdust, bark and firewood and grass are collected together, chopped into small pieces, thrown into clay jars and boiled so-so, which is also disinfection and sterilization.

Finally, put these messy things in the "brick hole" and put them in place, and finally break the edible mushrooms and use them as seeds, all you have to do in the future is to ensure that the temperature and humidity are guaranteed.

So another book of architecture was born, and Liu Jingtian decided to call it "mushroom farmland". As for how much you can gain, God knows. The fermentation and ratio of these raw materials can only be pondered slowly in the future.

Liu Jingtian as a carnivore, mushrooms can never be used as a staple food, so another building was immediately launched, that is, chicken farms and earthworm farms, earthworms can be raised as long as the rice field and plant fermentation, these two things have never been missing, I heard that it seems that it can be harvested in less than a month, and animal manure is also a good earthworm feed.

The only problem is that there are no chickens and ducks here, so the dogheads can only be told to catch live birds by all means, and the big rats seem to be able to do the same...... After thinking about it, he simply let the other dog heads continue to go to the river to catch crabs and field chickens, and now they have a lot of inferior bows and arrows in their hands, and these two tasks can be completed together.

And just like that, a busy month passed.

In the river near the cave, there are many fewer fish, the croaking of frogs on the shore is gone, from the river bank to the foot of the mountain, there is a kilometer long land, the grass and trees are withered, the large and small animals are extinct, and there are large and small "sinkholes" looming on the ground.

Liu Jingtian, who seemed to be a little bigger, was surrounded by nearly a hundred kobolds, and they looked nervously at the five eggs that Niu Jingtian was holding in his arms—this thing was only a little bigger than a goose egg, and it was trembling gently, and it was already covered with cracks.

"Well, it's coming out soon!" Liu Jingtian said with a yawn.

"Woo Woo ......" There was a long burst of dog barking, and the kobolds around him began to cheer.

After a while, five wet little "lizards" crawled out, staring at the dark underground space with big watery eyes and fleshy little claws in their mouths.

"It looks so delicious...... No, I mean, it's so cute, Kuku Kuku~~ Wait, it's a lizard! I think they're cute!? What a curious story is this, it must be a typo! No, no, Amitabha Buddha is empty, and the old man only loves Sora Aoi! Wait a minute, don't go, let me hug it for a while!"

The second generation of kobolds of Liu Jingtian's violent clique has finally come to this world - please refer to the cover of this book for the appearance.

For a long time, Liu Jingtian has ignored one thing, his dragon tooth soldiers are actually male and female. The females are about half the males, and the question is who can tell the difference between these lizards without breasts and buttocks.

The dragon tooth soldier himself has no sense of starting a family, as if he is just waiting for the organization to assign a daughter-in-law. I don't know if this is the peculiarity of the dragon tooth soldiers, or if the dog head is born with a lack of family values.

Fortunately, not long ago, when raising birds, Liu Jingtian noticed this problem, and this is a big deal! Is it okay that it hurts to pull out a tooth all day! So, more than 30 pairs of dogheads quickly became families, and in less than a month, five fresh dog-headed eggs were baked.

As an evil and orderly, xenophobic and violent organization, kobolds attach great importance to the development of the population!

Usually Liu Jingtian tosses them hard, but in the matter of "tooth extraction" is very troublesome, always entangled, otherwise with Liu Jingtian's inertia, it is really difficult to develop to the scale of today's nearly 100 kobolds, this is two tooth extractions!

What's even more sad is that you have to keep pulling ......

So these "dog eggs" are "highly valued from top to bottom". The problem is that the dog head itself is a semi-cold-blooded animal, and it is not good at maintaining body temperature, so it is naturally unable to hatch "dog eggs".

The wisdom in their DNA and veins awakened, and as a result, a group of dog heads began to collect rotten blades of grass as a breeding ground, intending to use the heat of fermentation to hatch eggs.

The "well-informed" Liu Jingtian said: "Just kidding, corrupt blades of grass...... Aren't you afraid of hatching pine eggs?"

The doghead was scared, and the original heated bed plan ran aground.

However, it is not only they who lay eggs, but the birds that caught them also laid some eggs during this time.

Therefore, the dog's head paid attention to the birds again, and there were wild geese in the bird farm that just laid eggs and hatched together!

Liu Jingtian said: "This is the wizarding world, aren't you afraid of hatching a dog-headed chicken body thing? I have vaguely heard of a thing called a chicken basilisk......

In the end, there was only one warm-blooded creature that met the requirements - Liu Jingtian himself.

Liu Jingtian said: "Let the old man hatch the eggs...... But the ugly words of this divine beast are in front of me, and it has become more and more difficult to find food lately, in case I see eggs when I am hungry...... Slip ...... Hehe, you know ......"

As a result, the work efficiency of the dog heads has skyrocketed, and Uncle Liu Jingtian must be served well!

The creatures in the wild are unlucky, and at night, when the dangerous birds in the sky return to their nests, large groups of kobolds, with burning hot throwing guns, haunt the river and the foot of the mountain.

Even a big guy can't bear nearly a hundred hot irons to greet him, not to mention that these dog heads never go far from the hole...... All the creatures who escaped with their lives deeply remembered the horrors of that land......

With 5 second generations of dogs, the dungeon seems to be more like a home, these little ones have received many preferential treatment, diet is also quite taken care of, and bird eggs are constantly being laid all day long.

The dog heads are busy, and the crypt of the Great Demon King of Liu Jingtian is developing vigorously these days. First of all, the mushroom harvest, all kinds of colorful mushrooms burst, conservatively estimated that there is also a ton, but unfortunately some of them are poisonous, and finally Niu Jingtian selected the three main crops with the highest yield, as the second batch of planting.

By the way, the raw materials for growing mushrooms have also been improved: this time a lot of excrement has been added, and there is also an additional fermentation process.

However, one thing that is not very reassuring is that the second generation of mushrooms turned out to be black...... Faster than expected, the second batch of mushrooms is also close to ripen.

Liu Jingtian said that it was okay if it wasn't poisonous -- it was for the dog's head anyway.

Earthworm farming is a similar problem, with high yields, fast growth, and a wave of brushing every month. But some of the earthworms mutated into half-meter-long chunks. Many of the birds caught saw this kind of horror feed, and many simply went on hunger strike, but it was a kind of silly bird that resembled a quail, and it didn't mind eating and sleeping silly. I had to chop the earthworms and pick them out and feed them, as long as there are stable eggs to eat, it is nothing to work hard.

"One science and technology is basically complete, mushroom fields, aviaries, fishing grounds, stone tools, pottery, and dog heads can also reproduce naturally, and the old man thinks that he can climb two books!"

After drilling in the soil for so long, Liu Jingtian's sensitive nose repeatedly found the smell of metal, but unfortunately this smell was emitted from the ground, and he could only smell and sigh before there were better tools. Now that there are clay buckets, bone shovels, and a huge number of kobolds, everything is finally in place.

After a few days of hard work, three mineral deposits were identified in the vicinity, although the number is large, but the amount is not large, two small iron ores, one unknown mine, probably silver and lead, are all a big lump buried in the soil, this round and slippery appearance, probably a meteorite, right?

"This is the rhythm of going straight into the Iron Age?

If you don't pursue the lofty technology of "blast furnace ironmaking", ironmaking is not too difficult, the ore is crushed, buried with carbon in a pile, keep burning, keep throwing carbon into it, persist for three or five days, and then smelt the worst iron material - sponge iron, so simple that it explodes, even refractory bricks can not be used.

There are so many impurities in sponge iron that it must be burned with charcoal to soften, and then kept forging (decarburization, desulfurization and dephosphorization), and it is pig iron after tossing a few more times, and the forging time is longer, and even wrought iron can be produced.

If there is a small blast furnace with a high enough furnace temperature, you can also melt pig iron and pour it on wrought iron to make steel filling, anyway, it is all junior and intermediate level chemical knowledge.

With the current skill level of kobolds, it is a waste to make weapons, and the "watermelon knife" is a warrior with a two-handed weapon, no matter how elite it is, how strong can it be? The wild animals here are all big guys.

What's more, their IQ is in a hurry, in case they cut themselves and their teammates...... Let's play with the short spear, it's difficult for this thing to accidentally injure friendly soldiers, and it saves iron.

In the future, the iron tools can be used to make some tools, nails, and fish hooks, and they can also play a great role, at least the stone tools and bone tools can be eliminated, and after thinking clearly, Liu Jingtian knew how to arrange it, so the two buildings were built in one go: a carbon factory, an ironworks, and a blacksmith shop.

"The second building seems to be poor in the textile industry, this is really not understood. And lately, wood has become more and more difficult to collect, and there are only small saplings left in a radius of one kilometer. Having said that, the growth rate of plants here is very fast, and in two months, the saplings can be two meters tall, is this a normal phenomenon? Is it possible that the growth of plants in this world is accelerating? Unfortunately, the strength is still insufficient, and we will have to investigate the ecological environment of this world in the future. ”

With the hatching of the "dog egg", the underground world was really lively for a while, and even Liu Jingtian was a little excited about being infected, but it didn't take long for him to calm down, because things were far from being so optimistic.

Remember that in many backgrounds, dog heads are long-lived species, especially the version of "Wizard of the Coast" - close to a hundred years. Even at twice the rate of human growth, it would take eight or nine years for a puppy head to grow into an adult dog head.

By that time, the number of teeth extracted was already astronomical......
