As the huge rock-like body of the unicorn fairy approached little by little, the protagonist gradually adjusted his mentality, and at the same time laughed at himself: As a human being, I have never seen any strong winds and waves, and today I was actually startled by an ant wearing a hat and clothes.

Once, the protagonist has not seen animals wearing clothes, such as some kittens, puppies, and rabbits raised by humans, but those are all human gifts enjoyed as "pets".

And this ant is not a gift, but the ability of its own group to make and wear clothes and hats.

The unicorn fairy has come to the protagonist and the oldest king, and its huge body is even shocking to the protagonist, not to mention the oldest king next to him. The protagonist notices that the oldest Wang's body has been trembling slightly, which shows that his heart is not at peace.

The worker ants and soldier ants who were in charge of greeting were even more unbearable, and in the face of the pressure of the huge unicorn, it was difficult for them to maintain the stability of the team, and the welcoming queue was chaotic, as if they felt a great threat from this unicorn.

The unicorn fairy finally stopped, and the big-headed ant "relic" warriors who accompanied the unicorn immediately surrounded the unicorn.

Among them, there is not much difference between the worker ant warriors and the worker ants of the Big-headed Ant Kingdom and the Divine Envoy King Legion, they are all wide-knotted big-headed ants, but the color of the carapace is generally more yellowish.

The soldier ant warriors of the "remnants" of the big-headed ant are a little different, and they all have a small piece of sharp flint stuck to their large jaws.

The protagonist doesn't notice this until they're close enough, and from a distance, the protagonist just thinks that the other person's jaws look a little strange.

These flints are supposed to have been processed, and they are sharp, elongated, cone-like flakes with polished edges, making them smooth and unusually sharp.

The flint flakes were glued to the bottom of a pair of large jaws of the soldier ants with an unknown type of glue, as if two sharp knives were tied to them. An angle is formed between the two flints, so that it does not interfere with the normal bite of the large jaws of the soldier ants.

These soldier ants actually have "weapons", and the protagonist quickly guesses the usefulness of flint knives glued to the large jaws, such sharp flint blades are obviously more lethal and penetrating than the chitin jaws that ants come with, and can easily pierce the carapace of ants or other insects, which is very useful for both fighting and hunting.

Moreover, judging from these flint weapons, the "remnants" of the big-headed ants were at least able to make polished stone tools, which is another example of speculating on their level of civilization.

Taking human beings as an example, the stone tools of human beings in primitive societies are divided into beaten stone tools and polished stone tools according to the production method.

Stone tools are stone chips or cores that are made from hard stones and laid with other stones. Stone tools can be divided into pointed tools, scrapers, chopping tools, carving tools and spherical tools, and their materials are mainly flint, agate, quartzite, quartz sandstone, hornstone and various siliceous rocks and other stones.

Among them, the pointed device has a sharp angle, and the two to three sides are repaired and beaten, and its size is generally suitable for holding it by hand. It can be divided into different types such as thick and heavy pointed organs, triangular pointed instruments, and small pointed instruments. It is roughly equivalent to modern drills and chisels, etc.

Scrapers are generally made by striking stones and leaving stone chips behind for reprocessing. According to its shape, it can be divided into straight edge scraper, concave edge scraper, double edge scraper, disc scraper, multilateral scraper, etc. The role is equivalent to a knife, planer, etc.

Choppers are often made of flat gravel, large stone flakes or stone cores, and are only processed many times at the edge of the blade to form unilateral or multilateral stone tools, and the main purpose is to chop large animals or make repair tools, so choppers can also be called chopping tools, choppers, hand axes, etc. Acts like a knife axe.

The carver is mainly used to carve and make wood products, which is relatively fine and plays the role of art knives such as carving knives.

Spheroids, as the name suggests, are spherical, on which the scar of the striking stone chips can be clearly seen. At present, there is no definite conclusion on the use of the spheroid, and it is believed that it was made to combat distant animals.

In general, although these stone tools are relatively rough and cumbersome, the appearance of stone tools is of great significance to the evolution and development of human beings.

The creation of stone tools by human beings is a purposeful creative activity, and the birth of stone tools has drawn a boundary between humans and the animal kingdom. Therefore, paleoanthropologists point out that the history of mankind began with the manufacture of stone tools.

Polished stone tools, on the other hand, are more advanced than stone tools, and were born in the Neolithic Age, 10,000 to 5,000 years ago.

The surface of the polished stone tools is polished. To make polished stone tools, you must first make beaten stone tools, beat or cut the stone into an appropriate shape, and then grind and process it on the stone.

There are many types of polished stone tools, such as axes, chisels, knives, adzes, hoes, etc., which are very similar to the classification of modern tools.

Locally polished stone tools began to appear in the late Paleolithic period, and in the Neolithic period, full-body polished stone tools were widely used. Even in the Bronze Age, polished stone tools continued to be used, serving both weapons and tools.

Compared with stone tools, polished stone tools are functionally suitable for fishing and hunting life, and the efficiency is relatively low; Polished stone tools are adapted to agricultural life, and labor efficiency is much higher.

It can be said that polished stone tools are a sign that human beings have entered a new era and entered an agrarian society.

The protagonist deduces from the "weapons" of these big-headed ant "remnants" soldier ant warriors that this group of mysterious big-headed ant "remnants" may have entered the social stage of farming.

At this point, the Legion of the Divine Envoy King under the command of the protagonist is the same, planting grass valleys and raising mealworms to obtain food, forming a primitive agriculture. Hunting and gathering are only complementary means.

But in terms of stone tool making, although the protagonist has been asking Xiao Mi's scientific research team to step up research in this area, but at present, it can only make thick stone knives to assist in cutting grass and wood, and it is not possible to make such a fine and thin blade like the soldier ants in front of him, which can be used as a single weapon.

It seems that the civilization represented by the big-headed ant "remnant" in front of him does have a lot to learn.

The protagonist braces himself and is determined to have a good exchange with the other party's queen.

At this time, the warriors of the big-headed ant "remnant clan" had already defended the one-horned fairy gong, and a soft rope ladder made of plant fibers was thrown down by the warriors beside the queen on the pavilion.

Subsequently, the queen of the mysterious big-headed ant "remnant family", the queen wearing a coat and hat, and the queen exuding a unique compound fragrance, came down from the rope ladder.

Gong Wei's unicorn fairy team opened a hole, and the queen, with two burly warriors, moved forward, walking towards the protagonist and the eldest king.
