"The formula of casting knives is extremely rare. Each part was exploring and creating by our ancestors for countless time and energy. According to incomplete statistics, the total number of casting knives created by humans is only close to one hundred. Some of them were lost as the casting knives fell in the ruined city, and the rest were scattered in different settlements."

"There are only 37 kinds of cast knife formulas that we master in Black Stone Cluster District, including 3 kinds of superior formulas, 8 kinds of intermediate formulas, and 26 kinds of lower formulas."

"The power of the soul sword created at different levels is naturally different in the final level, so even at the same level, the strength of the swordsman will be quite different due to the formula!"

"More importantly, a knife caster can only have a white knife in his life. Once he starts casting the knife, it cannot be changed easily. Therefore, having a good knife casting formula means a superior starting point for a knife caster!"

"The Sword Casting Guild has the most recipes for casting knives in the Blackstone settlement area!" the old man said loudly.

The students were full of yearning for hearing this, and they wanted to get the recipe and start casting knives now.

Lin Ze looked thoughtful. He recalled the red lotus recipe he drew, which seemed to be the recipe for the upper-level casting knife.

‘Red lotus (36% steel, 33% fire, 12% high temperature, 18% light, 1% sacred)’

"In other words, if you want to cast a 'Red Lotus' soul sword, you have to hunt insects and beasts with five attributes: steel, fire, high temperature, light and sacredness, and then absorb their soul energy strictly in proportion." Lin Ze thought to himself.

On the podium, the old man continued to say: "The more advanced the formula for casting knives, the more soul energy it involves and the more difficult it is to cast, and of course the power is stronger."

"The lower-level formula involves the least kinds of soul energy, generally only three. For example, the most common soul sword 'Shen Steel' in the Black Stone settlement area is a lower-level cast knife formula."

"The total number of soul abilities is required to create Shengang. Because of the common regulations of the three major organizations, I cannot tell you the complete formula ratio, but I can explain one of the soul abilities to you, that is, the 'steel' attribute soul abilities."

"This kind of soul energy comes from a kind of insect beast called Steel Soldiers. It is a basic soul energy. Almost all formulas contain this soul energy. However, the proportion of steel-attribute soul energy in the formula of "Shen Steel" is particularly high, reaching 80%. In other words, if it is necessary to hunt 1,000 soul beasts to absorb enough soul energy to cast Shengang, then it must contain 800 steel warriors!"

"Then teacher, how can we get the recipe for casting knives?" a student asked impatiently.

The rest of the people pricked their ears when they heard this, and they also wanted to know this question.

The old man smiled and said, "The easiest way is to join the three major organizations, namely the Knife Casting Association, the Autonomous Committee and the Blackstone Chamber of Commerce. Then you can obtain at least one lower-level Knife Casting Formula. Of course, if the talent and potential shown are excellent enough, it is not impossible to obtain intermediate or even higher-level formulas!"

"But this is still far away for you. When will you pass the assessment and successfully graduate and be promoted to an intern swordsman, you will have the opportunity to join the three major organizations at that time. Now let's study hard first." The old man poured cold water on everyone.

"Back to the issue of casting a knife, in this process, the white knife will gradually show corresponding characteristics and abilities as the soul energy is absorbed. At this time, the intern sword casting master will begin to have a certain strength. After the white knife absorbs enough soul energy according to the formula, it reaches 100%, it can completely evolve into a soul sword. At this point, the intern sword casting master can remove the previous two words "intern".

"Any soul sword formed has powerful power. For example, Shengang has the ability to cut iron and gold. Even the gold-eating insect with strong shell defense is comparable to that of gold and iron, it cannot stop Shengang's sword! Others include the "Vulcan God" who can control flames, the "Earl" who can absorb enemy blood and strengthen itself, and can create super-gravity areas, but the "White Dwarf" that is not affected by the sword caster himself, etc."

"The power of the soul sword is very strange. Of course, because its power is too powerful, the soul sword cannot always maintain its power and is hidden in normal times. Only when it is truly facing battle will the sword caster liberate it."

"liberation?"

"Yes!" the old man focused his head and said in a deep voice, "Every soul sword will have a corresponding liberation language. When the soul sword is cast, the corresponding liberation language will naturally appear in the mind of the sword-casting master. As long as you recite the liberation language during the battle, you can completely liberate the power of the soul sword!"

Seeing the students looking like they didn't understand, the old man raised his lips slightly and smiled, "It's better to see him than to say that, it's okay. Today I'll make an exception and let you see the true liberation with your own eyes."

Amid the students' expectant and excited eyes, the old man slowly pulled out the soul knife from his waist. With the crisp clanging sound, the snow-white silver sword light suddenly appeared in the classroom.

From the appearance alone, the formed soul sword and the white sword seem to be no different, but Lin Ze can keenly detect the oppression and threat that the soul sword in the old man’s hand brings to him. Obviously, as the old man said, the formed soul sword has a very powerful power, but it is not obvious.

This made him increasingly yearn for the power system represented by the Soul Sword.

After pulling out the blade, the old man held the knife in one hand, his lips stammered, and spoke in a low and fast manner:

"Crush him, white dwarf!"

As the low voice sounded, the soul knife in the old man's hand was instantly wrapped with a layer of dazzling white light. Several students closest to the podium were immediately dazzled by the light and couldn't help but close their eyes.

At the same time, the stagnant and powerful momentum suddenly spread and spread throughout the classroom in a blink of an eye. All the students only felt breathing tightly, and cold sweat suddenly appeared on their backs, as if they were staring at them by some terrifying giant beast.

"This is the liberation of the soul sword!" the old man smiled, then handed the soul sword slightly forward, and said in a deep voice, "Three times the gravity!"

After the words came, a heavy pressure suddenly came to the classroom. Everyone present felt their bodies sinking, as if they were wearing a layer of steel shackles. The heart beats rapidly, and the sound of blood flowing in the blood vessels seemed to be heard in their ears, and their chests were dull and almost vomiting.

Fortunately, the gravity came and went quickly. After only four or five seconds, everyone felt the pressure suddenly dissipated and couldn't help but lie on the desk and gasp.

Looking up, the white light on the surface of the soul sword in the old man's hand had dissipated and returned to its original appearance, but he had no idea when the soul sword was liberated.

After this, the students gained a deeper understanding of the power of the Soul Sword. Many people showed expressions of excitement and desire on their faces, and their eyes looking at the Soul Sword's "White Dwarf" were filled with envy and desire.

Lin Ze sat in his seat in a daze, staring at the soul sword "White Dwarf" intently, and the doubt flashed in his eyes.

For some reason, he always felt that the scene just now was a little familiar, and seemed to have seen similar scenes somewhere.
