On the drawings provided by Huang Manyun, the goal of Tianxiang's trip is here.

"It's a coal seam that's very easy to mine." Standing in front of a pit pried open with steel bars, Tianxiang picked up a handful of black scraps in the pit and thought happily. Although the drawings clearly stated that the coal seam was quite shallow from the ground, he was still startled by the black lumps of coal buried beneath the thin layers of turf and dirt.

This is because the layer of soil that covers it is less than ten centimeters thick. "With coal, a lot of things are much easier." Tianxiang quickly thought about the various aspects of the possible use of coal in his mind as he instructed his people to untie the bark basket on their backs. Load the loose pieces of black coal and set them aside in order. Wait for handling.

The basket for coal is large and sturdy. It was woven by women and old people from the bark of the trees that had been cut down and torn into strips. It's practical and lightweight. It is the most suitable for transporting coal. As for Xiaoqing, Tianxiang didn't let it sit idle. For more than a month, the insect beast had eaten a lot of the meat it had stored. Now, it's time for it to do its part.

A "camel" made of thick rope of steel and cloth is now firmly attached to its long and narrow back. It's a bit like the saddle that was used in ancient times for an animal called a horse. However, it does not work for people to ride, but for carrying more bark baskets. The shape of the camel resembles a strap across the back of the beast. At each end of the strip there are three circular rings of steel to accommodate the bark frame. Its function is to clamp the protrusion at the top of the bark basket on the tree, and in this way, it is fixed to the "pack". So as to achieve the goal of using the power of insects and beasts to transport coal.

When everyone was shouting to load baskets of heavy coals onto the "pack", Ye Zhanfeng suddenly noticed a rather strange movement of Xiaoqing. It was struggling to pull at the slightly soft layer of the ground with its short forelimbs, which were not very strong. Apparently, he seems to be interested in something buried in it.

In the center of where it was desperately digging, stood a stolon.

People who are in a hurry to rush back with a load of coal. Obviously, I won't pay too much attention to Xiaoqing's movements. Under the guidance of Tianxiang Sisense, the insect beast quickly gave up its own excavation. Instead, he obediently followed the team towards the base. Only the wind of war continued Xiaoqing's unfinished work along the partially dug out soil pit。。。。。。 "What is this?" That night, Tianxiang was in front of the fire lit with coals, and when he was seriously thinking about his next move, a ball of plant tubers the size of a head was also handed over from the hand of Zhan Feng next to him.

"I don't know, it was Xiaoqing who found out." Zhan Feng replied honestly. The tone of his mouth turned around: "However, this thing can be eaten!" ”

"Can you eat it? Are you sure? Zhan Feng nodded slightly. I passed a piece of it and it was obviously smaller. Something that is charred on the surface, but exudes a faint aroma.

Tianxiang had no doubts. He immediately took it and shook it hard. Suddenly, a white and tender inner petal was revealed. A rich fragrance with a hint of white gas also came to the face. "Good fellow, it smells so good!" Tianxiang took a bite hard, only to feel that the indescribable feeling of pleasure suddenly spread from his mouth. It has a taste that is more fragrant than the meat of insects. It is also clearly distinguished from the freshness and sweetness of meat. It is also a refreshing taste that has never been seen before. All in all. The feeling of this thing in the mouth is completely different from meat. It should even be said that it tastes better and sweeter than meat.

A person who has eaten meat all his life, and suddenly eats vegetables one day, I am afraid that he will also behave in the same way. Tianxiang eats quickly. In the blink of an eye, a fist-sized plant tuber was swallowed by him. Even the outermost layer of black scorched skin did not let go.

"Delicious! It's delicious! Where did you get it? Still unsatisfied, he wiped the black dust from the corner of his mouth and asked with interest.

Zhan Feng smiled and did not answer. Just a rather unexpected question. "Now, how do you feel?"

"Feelings?" Tianxiang looked around him and felt a little inexplicable.

"I mean, in the past, the plants are poisonous. You just ate such a big mass of plant tubers, didn't you have any reaction at all? ”

In Zhan Feng's eyes, there was obviously a hint of banter. Tianxiang was a little puzzled, could it be that Zhan Feng had different intentions? Deliberately make a lump of poison for me? Impossible? I saw that he let go of his thoughts and feelings in confusion, and walked around his body with the Tai Chi Method, but in the end, he did not find anything wrong.

The grins on Zhan Feng's face intensified.

Obviously, this is a joke. A good-natured joke. "Huh! How dare you lie to me? Tianxiang, who confirmed the facts, couldn't help but say: "Do you believe that tomorrow I will let you go alone to carry ten trips of coal?" ”

"Gotcha! Get! Get! Just kidding! Hearing this, Ye Zhanfeng hurriedly put away the smile on his face, and said, "Don't be so serious, okay?" Hehe! I've eaten it before you, and I'm sure I'm okay before I bring it to you. ”

In an instant, an indescribable emotion permeated Tianxiang's whole body. Before you're sure if the food is poisonous, try it yourself before handing it to a friend. How many people can do this?

"You're too careless, so bold, what if something happens?" Tianxiang couldn't help but feel that the corners of his eyes were a little moist. "Huh! I was absolutely sure that I would do it! Zhan Feng smiled: "This thing hasn't changed color in the water. Xiaoqing also likes to eat. That's when I took the plunge and took a bite. It wasn't until the evening that it was OK that it was put on the fire to roast and try. Hey! Unexpectedly, in this way, it actually became even more delicious! ”

Tianxiang couldn't laugh or cry. Just a simple test to determine that it is not poisonous? This Ye Zhanfeng, the courage is too big. Thinking of this, the previous emotion suddenly disappeared without a trace. He shook his head and said, "Wait a minute!" We'll see what happens in a few days. Just because you're okay now doesn't mean you'll be safe in the future。。。。。。 You! It's too careless! "That being said. In fact, Tianxiang knew very well in his heart that almost half an hour had passed since he had eaten the tuber. If there was any discomfort, it should have flare-up a long time ago.

From this point of view, this kind of thing should be able to be used.

"Tomorrow you take a few people out and get some more of this stuff back. I suspect that this is probably the kind of underground tuber mentioned in the books of the ancients - potatoes. "A little over an hour later. Tianxiang said to Zhan Feng. He was already completely sure that there would be no adverse reactions to eating this thing. In other words, this seemingly inconspicuous plot stem should be a substitute for insect meat.

The coal was placed in the corner of the base, stacked into a low knoll. To the great delight of all the clansmen, this kind of thing is really very resistant to burning. An inconspicuous lump of coal, enough to sustain burning for a long time. It's best to use it as fuel. However, the function of fuel is not exactly to heat a fire. They have an even more important role to play.

A few days later. A considerable amount of coal has been brought back from the mines. According to the plan. Tianxiang immediately started the work behind.

Pottery. Smelting.

These are two tasks that urgently need to be completed as soon as possible.

That's right, pottery. Hunters are no strangers. In fact, they discovered a long time ago that some clay that had been burned in fire for a long time would become hard and insoluble in water. Its texture will also become brittle. If you put the pre-kneaded clay mold into the fire and grill it for a certain period of time, you can get some simple utensils that are harder than the clay. Although the hunters didn't know why, they made something practical based on their experience. Such as: bowls, saucers, etc. However. This kind of firing cannot be carried out on a large scale. The reason for this is that there is not enough fuel.

A few days ago, Tianxiang ordered Li Bindi's team to dig out part of the gray-gold clay in the soil layer not far from the base. And according to their own requirements, part of the pottery mold was made to dry and set aside. At the same time, a simple kiln made of broken bricks and stones was successfully completed under his supervision. A batch of clay pots with lids, no more than the size of a palm, were put into the kiln in order. This is what Tianxiang thinks needs to be fired as soon as possible. As for the role, he didn't want to explain it to his clansmen for the time being.

Not far from the kiln, there is a pile of scrap iron stacked together. These things are the trophies that Xia Dong's team brought back when they hunted insects in various ruins for several days. Right now, Tianxiang is directing everyone to stack them one by one in the order of a layer of coal and a layer of scrap iron. Without a smelting furnace, Tianxiang could only take this most primitive method to obtain the iron he wanted.

Although, in his mind, there are all sorts of smelting methods. But for now, in the absence of any ready-made high states, this method is the most straightforward and simplest.

The speed of smelting is much faster than that of firing pottery. Both sides were ignited at the same time, and the coal pile mixed with scrap iron had completely burned out. The burning kiln is still hot to the touch. A pile of molten and solidified iron into a strange shape appeared in front of everyone. That's what Tianxiang needs - iron.

Although, this iron is not ideal. Iron ore on Earth contains carbon. As a result, the iron initially extracted from the ore is relatively soft. How to remove the carbon in it to achieve a relatively ideal hardness has become the most troublesome and headache in the smelting process. Although the ancients have practiced many methods for this, for the time being, the young patriarch can only take the simplest method - directly burn it with fire, and then repeatedly calcine. A piece of iron, which was relatively well shaped, was selected and fortunately played the role of a hammer. Through this primitive collision, the smelters obtained the first complete piece of iron. Or it would not be an exaggeration to call it "steel".

It should be admitted that Tianxiang is lucky. Although his smelting methods were backward due to the constraints of the conditions, in terms of his raw materials, he was far better off than the first blacksmith on earth. After all, he was making steel from scrap iron left over from the ancients, rather than taking pig iron directly from the ore and refining it into steel.

In other words, the ashes of the ancestors. On the basis of the current situation, these raw materials have been calcined. Tianxiang wants to make the earth, just fuse them again and remake them into the shape they need.

And just like that, complete steel bars appeared. Saws, this is what Tianxiang thinks should be made first. Among the vast ruins, all kinds of strange-looking trees grow everywhere. These trees are completely different from those recorded in the books of the ancients. Maybe it's because I want to adapt to the environment and survive! These trees have very few leaves. There are not many fruits. However, there is one thing in common - the branches are straight and thick. That's why Tianxiang wanted to make saws.

Before the winter, the wind of war once led people to cut back a few trees that were used for firewood. But what a felling it was! Use a few short daggers to cut tiny openings around the hard tree. Slowly hollow out, and finally push the tree to the 。。。。。。 The hunters used this primitive but helpless method to obtain the necessary fuel.

With a saw, this kind of thing will be extremely simple. Knife. A long knife large enough to cut through the hardest is the shell. It is also one of the items on the list of the most urgent needs to be manufactured. Throwing guns is really good to use. But for the kind of bug that is already close to his face. Instead of piercing one by one with the sharp tip of a spear, it is better to have a long knife at hand and cut it smoothly.

And some little things to bully it. For example: knives, scissors, axes, etc. These are important items that are urgently needed at the moment. Without the help of these things, many Tianxiang have already worked out, and the plans that will be implemented next cannot be successfully completed at all. There is a lot of scrap iron collected, which can be stacked into an "iron mountain". Compared with. Days of hard work by the hunters, the coal they had brought from the mines, were completely reduced to ashes under a fire. The amount of coal required in the smelting process is so large that even Tianxiang himself did not expect it. In desperation, he only regretfully ordered his people to first select some crucial things to build.

As for the future, Tianxiang has a new idea. He wanted to move the smelting site to the vicinity of the coal mine to shorten the transportation distance.

When the first pair of scissors had just been submerged in cold water and had just been casually polished on the stone, Tian Xiang couldn't wait to grab it, and happily trimmed his unkempt hair in front of a smooth piece of iron that could still faintly reflect the blurred figure. He couldn't remember exactly when he had last done such an activity. It seems that he must have returned from a hunt of his own, borrowing a pair of rusty broken scissors from a passing hunter with five of the fattest aphids. In this expensive and completely do-it-yourself way, the job of cleaning up the messy hair is done. At least nearly five years have passed since then.

Hair growing too long is an extremely inconvenient thing. obstruction of vision, insect breeding, dirty, messy...... Sometimes, the strange itch that comes from the roots of the hair almost wants Tianxiang to pull these obstructive guys out of their heads one by one.

With scissors, this situation can be solved naturally. All the clansmen were in a state of mad joy. Every new object that comes out of the hands of the forger causes a sensation. They never imagined that it would be so "easy" to make a precious reference book. Although striking iron is a strange job for everyone. But they can learn, they can grope. With wisdom and strength, at this moment, they finally embodied the most basic and incomparable difference between humans and animals.

Tools, we will make tools. At that moment, Tianxiang's prestige reached its highest point in people's minds.

It's just that he still has a doubt, a big one.

Liu Rui is an electronic person created by the ancients, that is, he has knowledge long before himself. According to his own words, he has been in this world for hundreds of years, and since this is the case, it is naturally impossible for him not to know the manufacturing methods of these simple tools. But why had his people never done this kind of work for hundreds of years?

Could it be that all the words that Liu Rui once said to himself were false? Are they all used to cover up an ulterior motive? Tianxiang didn't know if his judgment was correct. Such doubts only flashed in my mind for a moment. After all, even if Liu Rui has any problems, at least, he has shown complete surrender to himself now. Moreover, compared to Liu Rui, who is a puzzle, he has more important things to solve.

Xiaoqing has begun to grow up gradually, and after this period of domestication, because, compared to Liu Rui, who is a puzzle, he still has more important things to solve. It has come to terms with its current situation, and it is quite nourishing. This made Tianxiang can't help but give birth to a strange and bold idea in his head. "Capture more insects and beasts and form a cavalry of insects. Just like ancient humans used to tame animals like horses and use them as their riding objects! ”
