"Please give me some advice." Ren Daoyuan knew that after three months of hard work, he had begun to gain Luo Zi's trust. Of course, Luo Zi might not have the intention of using his work, but after all, getting trust is extremely beneficial to him.

Luo Zi was not only satisfied with Ren Daoyuan's learning ability, but also more satisfied with his attitude, but did not do anything out of the ordinary because he was kind to him. He got up to work before dawn every day, and returned to his residence until sunset and received his permission.

In fact, the work they do is not less than other slaves, and they do not need to be watched by others. Because of this, the guards are not dissatisfied with Ren Daoyuan.

"Xiao Ren, you should be a warrior, your cultivation is not low, you should have some understanding of the warrior." Luo Zi did not explain the dust in his hand, but talked about the warrior.

Ren Daoyuan was shocked at first. He had a high-level human cultivation level, and there were many warriors here, which was unconcealable. Fortunately, the high-level human cultivation level was nothing. Most of the guards were better than him, so no one cared about it. But what was this mean when Luo Zi mentioned cultivation level?

He guessed in his heart, but he didn't show any signs of his face, nodded and said, "Of course I know that the human rank is the lowest, then the earth rank, and finally the heaven rank."

"Where is above that heaven?" Luo Zi asked with a smile, squinted his eyes.

"Above the Heavenly Level?" Ren Daoyuan looked confused. This was impossible to answer. You must know that in the eyes of ordinary people, the Heavenly Level is the most powerful warrior.

"Xiao Ren, above the heaven level, there are three levels, namely the star level, the moon level and the yang level. That is the real master." Luo Zi raised his head and looked at the sky, his face full of yearning. No one doesn't want to become a strong man, but the talent base and family environment make it impossible for most people to become a real strong man. Ninety-five percent of people who can reach the top level of the human level are the pinnacle.

Luo Zi was silent for a moment and continued, "What are the weapons created by the craftsman for?"

What is this problem? Weapons are naturally for people to use. Ren Daoyuan is not sure about his intention, so he will answer honestly.

Luo Zi nodded: "You said it well. No matter how good the weapons are, they are for people to use. But different people naturally use weapons differently. Essential iron is used by ordinary people, and fine steel is used to equip the army and the most demanded. Meteorite is the treasure of aristocratic families, and some wealthy low-level generals will also choose. Black iron is more expensive, and usually only senior generals and children of the imperial family can afford it."

Ren Daoyuan nodded repeatedly, and he naturally knew about these things. Like the Ren family, they bought the Meteoric Iron Ring Head Knife at a high price. Yanqing Mansion is not without black iron. Not only is it small, but it is too expensive. Even if the Ren family can afford it, they dare not buy it casually, as it will attract attention.

"You know all of these, but do you know what weapons Stephen Chou uses?" Luo Zi suddenly asked this question. Ren Daoyuan was confused at first. Stephen Chou used a black iron weapon. He looked at the dust in his hand and said shakingly, "Step Chou uses a star stone?"

Luo Zi laughed and looked at Ren Daoyuan with satisfaction: "You are right. Star Chow uses Star Stone. This is how the name of this Star Stone comes from. The weapon made by Star Stone is not only sharp, but more importantly its quality. This starts from the Heavenly Level and the Star Stone Strongman themselves, so you can understand it."

"Yes?" Ren Daoyuan looked curious. He was born in a noble family. There were as many as five heavenly ranks in his family, and three were common. Ren Daoyuan didn't see that the weapons they used were different, but the quality was slightly better, and he also used the Hundred Refining Waist Knife.

Luo Zi continued: "The heavenly level has innate energy, which is something we will never understand. The heavenly level strongman can inject the innate energy into weapons and its power increases greatly. This innate energy is extremely powerful. If it is injected into ordinary weapons, it will not take long to destroy the weapon because it cannot withstand the innate energy. Therefore, the heavenly level strongman uses at least a hundred-refined steel weapons, preferably meteorite or black iron, which will be more durable."

Ren Daoyuan naturally knew the innate energy, but he didn't expect that there was such a particular point. He nodded repeatedly and looked at Luo Zi with admiration. He was indeed the top scholar in every industry, and a great craftsman, who actually had to understand this knowledge.

Feeling the admiration in Ren Daoyuan's eyes, Luo Zi felt even more happy and continued, "Star Master also has power in his body. I don't know what power it is. Anyway, it is stronger than the heavenly-level strongman. Even the black iron weapon cannot bear it for a long time. Only weapons made of star stones can be used."

Ren Daoyuan nodded repeatedly, but he thought to himself, he didn't know what kind of power Star Chou had, and he thought that this master craftsman didn't know, he only knew the function of Star Stone.

"Where is the moon-level strongman?"

"Yuejin." Luo Zi opened his mouth and spit out two words, but looking at his face, Ren Daoyuan guessed that he had only heard of the name, but he was afraid he had never seen what Yuejin looked like.

"Where is that day-level strong man?" Ren Daoyuan continued to ask. Of course, he was also very curious about this. These things were something he could not learn from the Ren family.

"Daily-level powerful man, Yang Shen..." Luo Zi shook his head slightly and did not answer. He didn't know. Yang Shen is the most powerful warrior in this world, a godlike existence. How could Luo Zi, a great craftsman, know what weapons they use?

Not to mention the Yang Shen, even the weapons of Yuezu were not made by the master craftsman. The star stones in his hand made him suffer. It was too difficult to make weapons like this thing.

The star lime is raucous and inconspicuous, but it has a higher melting point than gold. So far, Luo Zi has not been able to melt a whole piece of star stone, so he naturally cannot make weapons.

"Okay, don't think too far. We can't get in touch with the gods like Yuezu and Yangshen. Let's talk about the star stone in front of us. The melting point of the star stone is extremely high. Even if you throw it into the iron smelting blast furnace, it will not melt. If you want to build a star stone weapon, you don't have to think about it." Luo Zi said.

"Then..." Ren Daoyuan looked confused and could not control the weapon. How could he use it to play with it?

Luo Zi's face showed a hint of brilliance: "If we want to completely melt the star stone, we mortals are useless. Only the greatest Taoist master can do it."

The Taoist master may melt the star stone? Ren Daoyuan was confused. Why didn’t he know? It seems that he should study and study the things in his dreams carefully. The time span of dreams is very large. In Ren Daoyuan’s opinion, it took at least one or two hundred years. He had been able to sort out the dreams for ten years. Now he has only been watching for a few months. And he still chose the parts he is interested in, and the most of them were not seen.

If Luo Zi was talking about the truth, I think in my dream, I would definitely find something related to Star Stone and Moon Gold.

Luo Zi didn't know what Ren Daoyuan was thinking and continued, "Old Luo, I have lived for more than fifty years and spent countless efforts. Finally, I came up with a complicated solution. Although I could not melt all the star stones, I could get a little bit from them. As long as I add this little bit of star stone to the weapon, I can greatly improve the quality of the weapon."

I see.

"Xiao Ren, this is my secret of not being passed down. You must swear that you must not reveal a word." Speaking of this, Luo Zi looked serious. This is the truth. Most of the reason why Luo Zi can become a master craftsman and be able to make better weapons than other masters is this secret of not being passed down.

Ren Daoyuan raised his right hand and swore a serious swear. Although he was funny in his heart, he still made a sincere vow. After all, this was the lifelong hard work of the old craftsman, so he naturally would not pass it on to others. But he had to study carefully at night how to deal with this star stone.

Speaking of which, Luo Zi's methods of dealing with star stones are indeed very complicated. Since the iron smelting technology in Jiuzhou has reached a limit, the temperature of the furnace is also certain, and it is difficult to increase it a little more. And this little improvement will not be of much use to melting star stones.

Since the temperature cannot rise, Luo Dajiang will find another way out and figure out how to reduce the melting point of the star stone. Use the liquid from dozens of plants to prepare a solution. When melting the star stone, while increasing the temperature, the solution is poured on the star stone. Under the dual action of water and fire, after several days, a little bit of iron juice can be melted from the star stone.

There are many mixed materials for this kind of star stone iron juice and it needs to be filtered again before it can be used. In fact, Luo Zi knew in his heart that the star stone iron juice obtained in this way looked very clean, but its actual quality was still quite poor, and it was not a little worse than star stone.

Even if it is bad, this is still the star stone iron juice, which cannot be compared with ordinary iron. As long as the star stone iron juice is added to the weapon, the quality of the weapon can be greatly improved according to the amount added. This is Luo Dajiang's secret that has not been passed down.

Ren Daoyuan made a vow and naturally got the solution formula. After a complicated procedure, he finally got a large bucket of turbid liquid and handed it to Luo Zi. However, Luo Zi did not do it immediately. Instead, it took another two days before he came back with the bucket and was about to start melting the star stones. At this time, the solution in the bucket had turned pink.

Ren Daoyuan smiled bitterly, saying that this is the case with this craftsman. It seems that the recipe he gave him was incomplete at all. He also needed to add other things to become a real solution. This old man finally kept his hand.

He guessed well. In a few months, even if he likes Ren Daoyuan, he would not be able to teach him his lifelong efforts. The solution he had prepared before was almost completed. As long as he added a few materials, he could get the real solution. Teaching Ren Daoyuan was to use him as a small worker, an obedient slave worker, which could free him from the complex and boring labor.
