The primordial era began with the Upper Cave Man.

The world within the pot has now moved from the Bronze Age to the Iron Age. The reason for this rapid progress is mainly due to the local environment.

To be more precise, the land where Luo Zu is located has little copper but plenty of iron, and even fewer other precious metals. In addition, there are certain metallic materials hidden in the soil that Luo Zu cannot analyze with his current level of understanding of creation.

This is why the materials and tools of the small human race in the world of the pot were updated so quickly. The Bronze Age had only just begun when it quickly turned into the Iron Age. Fortunately, Luo Zu had made preparations in advance and guided the small human race to start building blast furnaces so that they could smelt iron and make steel.

However, the leap in productivity was not achieved overnight. Due to the forced growth, many supporting capabilities did not increase in a consistent manner, which led to the slow production of steel. Fortunately, Luo Zu was backing them up, ensuring that the land had favorable weather and few major natural disasters every year. Grain yields were abundant every year, and the number of newborns exceeded 100,000 every year. This period can be described as the golden thirty years for the small human race.

Despite such abundant production, the small human race actually entered the era of slavery.

Luo Zu couldn't stop it even if he wanted to; it was the general trend. After people were well-fed and clothed, some began to indulge in pleasure, which further led to corruption among the upper echelons of the small human race.

Luo Zu did want to change this situation, but the decay had already invaded the small human race. To remove this rotten flesh, a human cleansing plan was necessary.

Unless mind control is applied to the smaller human races, their tendency to indulge in pleasure will likely be impossible to eradicate.

As for where the slaves of the slave era came from, they were also from small human races. Over the past few hundred years, the small human races have expanded to three million people. Although only one-third of the land has been explored, some areas were isolated from the outside world due to certain accidents. Then, due to certain reasons, they made contact again. However, both sides have developed for many years and have different leaders. Thus, conflicts arose, and war broke out. After the war, the losing side lost its human rights and became slaves.

The main reason for this is that the world within the pot has also been expanding. The speed of human expansion cannot keep up with the expansion of the world within the pot. Now the world within the pot is ten miles in diameter, with land occupying a quarter of the area and the rest being water.

That vast sea was created by Luo Zu through his magical powers, transforming the freshwater in the mountains into seawater. Although Luo Zu did not know the specific composition of seawater, he knew that adding salt would make it so. Guided by this idea, he added the brine from the salt pool in the cave. The effect was remarkable; the water became much saltier. Unfortunately, no large animals have been born in it so far. Only a very small number of microorganisms have shrunk in size and are willing to live in it.

Returning to the topic of steel production in the world within the pot, under Luo Zu's supervision, the annual output has now reached three hundred catties (the normal three hundred catties). In order to achieve such a production, Luo Zu expended a great deal of spiritual energy, repeatedly replacing the land beneath the feet of the small human race. Moreover, in order to ensure that the terrain remained completely unchanged, he spared no effort and exhausted his energy. Finally, through recycling, he obtained this one-ton hundred-refined steel ingot in his hands.

The term "Hundred-Refined Steel" refers to the product of iron being repeatedly forged and quenched after being forged. In order to achieve this unified effect, Luo Zu collected a large amount of steel and then controlled the fire to smelt it, followed by repeated hammering.

Fortunately, Luo Zu is no ordinary person now; he is a "caveman" who has cultivated Qi to become a spirit. Therefore, even with such intense blacksmithing day and night, he is still able to complete his daily work.

That's why Luo Zu sighed, "It wasn't easy."

But no matter how difficult it is, the project schedule cannot be neglected.

The embryonic form of the ritual implement is not yet complete.

According to Luo Zu's plan, the creation of a magical artifact should begin with the creation of a suitable embryo, followed by repeated refinement and finally, after meticulous carving and polishing, the artifact should be completed.

As for the method of refining, it lies in Qi.

Qi encompasses spiritual energy, spirit, and magic. Therefore, by refining with Qi, one can create the most suitable magical artifact for oneself.

Because through the constant refining and purification, it has already taken on the "shape" of its master.

Therefore, it can be described as a ritual or even "training".

It's like how Luo Zu tamed the wild beasts he raised in his tribe.

As for Luo Zu using such a large iron ingot, it will be quite a challenge to refine and use it in the future.

Korozu has a world within a pot.

The world within the pot is not just the space where the small human race lives; there is another layer of space beneath that land, which can be used to store Luo Zu's large iron ingot.

In addition, Luo Zu has been forging this large iron ingot in this space all this time.

However, the world within the pot is still unable to sustain the activities of such a large-scale living being, so when Luo Zu was forging iron, he created a clone that was the maximum size that the world within the pot could contain.

A "giant" that is a foot tall.

Otherwise, it would take an unknown amount of time to forge such an iron ingot from a clone the size of a hair.

The embryonic form of the magical artifact has now taken shape. Luo Zu is preparing to forge an iron sword, which may be six feet wide, ten feet long, and the thickest part of the spine will be seven inches.

It's just a thick door panel.

Using such an iron sword, one would probably need to shout several times before it's effective.

He shouted out the name of the sword move without even using it once.

Although it was somewhat shameful, it seemed to have a certain effect of intimidating the enemy.

And in the future, when he can fly on his sword, his large, door-sized sword can carry even more passengers.

It's truly a practical and helpful tool for home use, absolutely wonderful!

Every swordsman of the primordial era needs such a fine sword.

The refining of magical artifacts is a lengthy process. Although the world within the pot can speed up the "time," a one-ton iron ingot is still quite large, and Luo Zu's clone is only three feet long. The amount of Qi he consumes each day is also limited. Therefore, Luo Zu estimates that it will take three months to refine the artifact into its final form.

The three months here are the three months of primordial chaos, which in the world within the pot is equivalent to more than 120 years.

It was also a long period of time.

As time went by, the lives of the "upper cavemen" continued. In addition to hunting, the hunting teams now had a very important task: to find new settlements.

Moving away from the cave was an inevitable thing; if the "Cavemen" wanted to develop, they had to leave this deep and dark cave.

Although it sheltered the "Upper Caveman" tribe through the most difficult days, and everyone had a deep affection for it, it was time to let go without too much hesitation.

We should all live under blue skies and white clouds, not in darkness.

Just as Luo Zu was about to refine the magical artifact into its final form, good news arrived.
