Swallowing the Stars: I Have a Primordial Dao Seed

More than ten years have passed since Zhou Yuan successfully forged a third-order primal force weapon.

Over the past decade, Zhou Yuan's life has been regular and fulfilling: every day he mass-produces third-tier Earth Profound Blades in the real world, accumulating wealth and weapon-forging experience; the rest of his time is spent immersing himself in comprehending the secret runes. In order to break through the bottleneck of fourth-tier weapons, he spared no expense to buy a fourth-tier Mountain-Splitting Blade and studied its internal law rune structure day and night.

At this moment, in the castle's training room, the silver Mountain-Slaying Blade was suspended in mid-air, its blade trembling slightly, as if muttering to itself: "I didn't expect to actually grasp the basics of the fundamental laws of space."

This was precisely what Zhou Yuan had created using his ever-changing secret technique. Over the years, he had delved into the secret patterns of the Broken Mountain Blade in the form of a weapon, simulating the trajectory of the patterns countless times, and sensing the earth-based and spatial-based laws within the Broken Mountain Blade.

As Zhou Yuan's understanding of the secret patterns deepened, he was pleasantly surprised to find that he had unknowingly touched the threshold of the fundamental laws of space—a completely unexpected delight.

It should be noted that the fundamental laws of space are among the two most obscure and difficult-to-understand superior laws in the universe. Many realm lords have struggled for tens of millions of years to even begin to grasp them, yet Zhou Yuan successfully entered the realm simply by comprehending the secret runes of a fourth-tier weapon. This talent is enough to make countless cultivators envious.

What excited him even more was that the Earth Origin Law Secret Pattern in the Broken Mountain Blade also allowed him to reach a higher level of understanding of the Earth Origin Law, and he also had some initial ideas for creating his own secret technique.

"Looks like this Mountain-Splitting Blade was a great buy." Zhou Yuan reverted to human form, a smile playing on his lips. Comprehending the secret runes not only allowed him to master the core structure of a fourth-tier weapon, but also enabled him to break through to the Law Realm—a double win.

Without the slightest delay, Zhou Yuan immediately entered the virtual universe and began simulating the forging of a fourth-tier Mountain-Splitting Blade. The forging difficulty of a fourth-tier weapon is more than one level higher than that of a third-tier weapon.

Not only does it require more precise control of the Force, but it also requires simultaneously mastering the power of two laws to inscribe the secret runes. The slightest mistake could lead to complete failure. Even with the virtual universe as a practice platform, Zhou Yuan dared not let his guard down.

Days passed by like this, and Zhou Yuan switched back and forth between the real and virtual universes.

In reality, his skill in forging third-tier Earth Profound Blades has reached a level of perfection, and every move he makes exudes the demeanor of a grandmaster. The quality of each blade is consistently at the top level.

In the virtual universe, he had to start from scratch, trying again and again to forge a fourth-order Mountain-Splitting Blade, experiencing the mystery and difficulty of the two kinds of law runes.

Occasionally, he would be invited to exchange cultivation experiences with several realm lords of Nan Yun Star. These realm lords were all ancient monsters who had lived for hundreds of thousands or even millions of years, and each of them had their own unique insights. Discussing the laws and understanding with them often enlightened Zhou Yuan.

In this rhythm of work and rest, several decades have quietly passed.

Over the decades, Zhou Yuan's mastery of the fundamental laws of space has steadily improved, long past the threshold of entry, and his application of spatial power has become increasingly skillful; his understanding of the fundamental laws of earth has also deepened, and the two laws have formed a wonderful balance within his body.

In the virtual universe, his success rate in forging fourth-tier Broken Mountain Blades increased from single digits to 100% accuracy, with his skills being in no way inferior to those in forging third-tier weapons in reality.

"It's time to try it in reality." Zhou Yuan looked at the perfect Mountain-Slaying Blade floating in the virtual universe, a determined glint in his eyes.

Back in the weapon-refining room of the castle in reality, Zhou Yuan took out the materials he had prepared beforehand from his spatial ring: hundreds of tons of D9-grade earth-attribute metal Star Iron, and one ton of D9-grade space-attribute metal Void Silver. These materials were extremely valuable, with a total cost exceeding one million cosmic coins. Once successfully refined, the finished product could sell for at least one hundred million cosmic coins, yielding a profit of up to a hundredfold.

However, the forging of fourth-tier weapons is extremely risky, with a high failure rate in the early stages. If it weren't for the virtual universe that allows for early simulation practice, the material losses alone would have been enough to bankrupt Zhou Yuan.

"Beibei, start the smelting mode and set the temperature to 30,000 K." Zhou Yuan's tone was solemn. This was his first time challenging a fourth-tier weapon in reality, and he could not afford to make any mistakes.

"Beibei, start the smelting mode and set the temperature to 30,000 K." Zhou Yuan's tone was solemn. This was his first time challenging a fourth-tier weapon in reality, and he could not afford to make any mistakes.

Star Iron has an extremely high melting point. The bright white aura inside the furnace quickly rose and soon turned into a terrifying pale purple. The temperature of the entire refining room rose sharply, and the surrounding metal supports were heated until they turned slightly red.

Zhou Yuan steadily threw hundreds of tons of Star Iron into the furnace. The metal block softened at high temperature and then gradually turned into silvery-gray molten metal, with tiny specks of starlight shimmering inside, like a condensed galaxy.

After the Star Iron had completely melted, Zhou Yuan took out the ton of Void Pattern Silver and carefully added it into the furnace little by little. The fusion of Void Pattern Silver and Star Iron was a crucial step in the entire refining process. The two metals with completely different properties were very likely to repel each other, and the slightest carelessness would lead to fusion failure and all previous efforts being wasted.

Zhou Yuan fully activated his mental power, breaking down each piece of hollow silver into nano-sized particles and guiding them to evenly integrate into the molten star iron. His mental power acted like the most precise instrument, sensing every slight change within the molten metal and constantly adjusting the output of his primal force to ensure the perfect fusion of the two metals.

A full hour passed, and when the last trace of Void Silver merged into the Starry Iron, the molten metal in the furnace finally turned into a peculiar silvery-purple color, with starlight shimmering inside and faint spatial fluctuations—the fusion of the two metals was successful.

Zhou Yuan took a deep breath and immediately began the most crucial steps: tempering and engraving.

Zhou Yuan mobilized all the primal force within his body and poured it into the smelting furnace. While using his primal force to comb through the molten metal, allowing the energies of the two metals to fully merge, he also inscribed the secret patterns of the Broken Mountain Blade into the molten metal.

The runes of fourth-order Force weapons are extremely complex. The patterns of the Earth Law and the Origin Law of Space are intertwined to form a precise network of laws. Any deviation in the pattern may lead to the failure of the entire forging process.

Time passed slowly, and fine beads of sweat appeared on Zhou Yuan's forehead as his mental energy and primal force were rapidly depleted. His eyes were fixed on the smelting furnace, not daring to be distracted for even a moment. Every surge of primal force and every flow of mental energy was precise to the extreme.

Three days later, the quenching of the molten metal was nearing completion. The silvery-purple aura was so intense it seemed almost tangible, and the fusion of the two metals within was flawless. At this moment, the final law rune was also inscribed, the earth-yellow earth law rune perfectly combined with the silver spatial origin law rune, forming a stable loop.

"It's done!" Zhou Yuan felt a sense of relief and slowly withdrew his primal force. The temperature of the smelting furnace began to decrease slowly. When the last trace of primal force was drawn out of the furnace, the law fluctuations of the blade reached their peak. The dense earthy weight and the depth of space intertwined, emitting a terrifying pressure, which then slowly subsided.
