Douluo Continent: Heaven rewards diligence, Tang San's defenses are breached by liver damage.

Filled with curiosity, Lin Chuan's consciousness sank into his mind and began to browse through the book, "The Book of Instruments".

After a while, he came to his senses, a look of surprise flashing in his eyes.

It turned out to be a book about weapon crafting, which detailed many weapon crafting techniques. After learning them, one could forge different materials into the desired magical artifacts.

Moreover, it also contains a method for refining one's natal treasure.

Upon seeing this passage, Lin Chuan's mind began to stir.

"They arrived just in time. It seems there's another way to deal with the soul bone in our hands."

Aren't three soul bones excellent materials for refining weapons?

Without integrating it into the body, it can unleash even greater power, making it more cost-effective than direct absorption.

Most importantly, Lin Chuan possesses Golden Flame Earth Fire, which can be used for refining weapons.

"Wow, this has been a huge help!"

Originally, Lin Chuan had planned to absorb the three soul bones, but now that he had obtained this "Book of Weapons," he immediately abandoned the idea and instead wanted to integrate the three soul bones into his own martial soul.

It won't necessarily cause the martial soul to evolve, but it will definitely take another step forward.

Having memorized the relevant techniques in the "Book of Instruments," Lin Chuan flashed back into the cave.

There are three noble professions in the heavens: weapon refiner, spirit refiner, and alchemist, and now Lin Chuan has acquired all three skills.

Aside from refining spirits, alchemy and weapon crafting are quite similar.

Having already mastered the third-grade alchemy technique, Lin Chuan naturally found learning weapon crafting quite easy.

"Let's give it a try!"

Lin Chuan took out the Fire Dragon King's torso bones and then activated the Golden Flame Earth Fire to refine them.

With a 'whoosh' sound, a crimson flame appeared on the surface of the torso bones, ruthlessly isolating the golden flame earth fire and preventing it from getting any closer.

Upon seeing this, Lin Chuan's eyes flashed with a sharp light. He changed the fire control hand seals, and the Golden Flame Earth Fire immediately split into several strands of light flames, which instantly enveloped the crimson flames and the torso bones together, beginning the long refining process.

But soon, Lin Chuan waved his hand and dispersed the golden flames.

"No, the Fire Dragon King's torso bones are too resistant. Although the Golden Flame Earth Fire can refine them, the process will be very long and too slow."

Lin Chuan shook his head slightly, clearly dissatisfied with the situation.

But there's good news too; at least it proves that soul bones can be refined!

He sat there, lost in thought.

A moment later, Lin Chuan put away the Fire Dragon King's torso bones, closed his eyes, and circulated his soul power into his dantian.

[You've diligently nurtured the Earth Fire once, and achieved some results; the quality of the Golden Flame Earth Fire has slightly improved.]

Chapter 73 Refining the Martial Soul

The Soul Master Competition was approaching, but Lin Chuan remained inside the Ice and Fire Yin-Yang Well.

Aside from studying the theory of weapon crafting and nurturing the golden flames of the earth, he spent his days refining medicine.

Every so often, Shui Lanxin would enter Sunset Forest to deliver medicinal herbs, and then take away the finished pills that Lin Chuan had refined.

The market for elixirs remains hot, and demand even exceeds supply.

However, Lin Chuan did not increase production. Although he didn't understand business very well, he at least understood the principle that scarcity increases value.

Moreover, he also had other things to do.

After meeting again, Shui Lanxin left Sunset Forest alone.

A few days later, another batch of ore and various forging materials were delivered.

With sufficient financial support, Lin Chuan immediately began to put his ideas into practice. A large amount of ore was turned into inferior magical artifacts, which were not easy to handle, so he could only leave it to the Shui family to deal with.

As a result, another batch of magical artifacts that can unleash magical power through the control of soul force have appeared on the market.

It wasn't that no one wanted to interfere, but after Dugu Bo took the initiative to stand up for him, those forces with ulterior motives also chose to restrain themselves.

The intimidating power of a titled Douluo is evident.

Lin Chuan was unaware of everything that was happening in the outside world.

[You've diligently nurtured the Earth Fire once, and achieved some results; the quality of the Golden Flame Earth Fire has slightly improved.]

"Pfft!!!"

The golden flames surged, and the power they emitted also increased significantly.

"Finally, it's done! Ninth-grade Earth Fire!"

Lin Chuan breathed a sigh of relief, a hint of joy flashing in his eyes.

It was worth the six months he spent conceiving; now the flower has finally blossomed and borne fruit.

Earth Fire is divided into nine grades, and it can be nurtured from the lowest grade all the way up to the highest grade. Lin Chuan has been using the methods recorded in the "Alchemy Manual" to nurture the Golden Flame Earth Fire for so long, and he has finally managed to barely reach the grade.

Lin Chuan swallowed a fasting pill and closed his eyes again.

After meditating quietly for three days, my spirit and soul were in their best condition.

"let's start!"

With a wave of his hand, he took out the Fire Dragon King's torso bone, opened his mouth and spewed out golden flames. He then made a series of hand seals, and the golden flames instantly split and enveloped the entire torso bone.

The upgraded Golden Flame Earth Fire is more powerful, but the refining process is too long and consumes a lot of soul power. Fortunately, Lin Chuan was prepared.

While maintaining the earth fire, he also swallowed pills to restore his soul power.

What follows is a protracted battle.

Three days later, the crimson flames on the surface of the Fire Dragon King's torso bones finally dissipated, and the Golden Flame Earth Fire began to refine the torso bones, showing signs of melting.

After more than ten days, the entire torso bones had turned into a thick, reddish-brown liquid.

"Get one!"

Lin Chuan exhaled a breath of stale air, took out a jade box, filled it with the red liquid, sealed it, sat cross-legged to restore his condition to its peak, and then began to refine the Water Dragon King's skull.

Another month has passed in the blink of an eye.

After overcoming numerous hardships, the three soul bones were finally refined into a pure liquid.

The refining process was also halfway successful.

After resting for a few days, Lin Chuan stood in the cave with a solemn expression, while the jade box containing the soul bone liquid was quietly placed on the ground in front of him.

In addition, there were some processed auxiliary materials.

Even the Night Shadow Blade he bought from Gengxin City was melted down into molten iron by Lin Chuan.

"it's time!"

All is ready except for the opportunity.

Lin Chuan waved his hand, and all the jade boxes opened, with various materials flying out of them.

He spewed out golden flames of earth fire, which landed on all the materials, causing the entire cave to shimmer with dazzling golden light. At the same time, under the guidance of his spiritual power, the various materials began to slowly fuse together.

The whole process was quite slow, and Lin Chuan looked serious, not daring to be careless in the slightest.

Fortunately, although it was quite energy-consuming, it was still managed to go relatively smoothly.

All the materials are fused together. Under normal circumstances, this would involve shaping them with spiritual power and then fusing them with blood essence, thus successfully crafting the natal treasure.

However, Lin Chuan didn't need to go through such trouble; he could simply integrate it into his martial soul.

Although Douluo Continent is jokingly referred to as a fantasy basement, it is not without its merits. At least, the martial spirit would be considered a talent in other worlds.

Leaving aside beast spirits, weapon spirits can be considered as innate attributes.

Lin Chuan grasped the bow in mid-air, and a simple, unadorned black longbow appeared in his hand. He ran his hand gently over the bow, and his gaze suddenly became firm.

"Today is the day you transform!"

Releasing his grip, the black longbow flew straight into the flames.

Lin Chuan quickly used his mental power to control the viscous liquid, evenly coating the bow. He then made a hand seal, causing the golden flames of earth fire to flicker continuously.

Catalyzed by the flame, a viscous liquid composed of various materials begins to blend into it.

Lin Chuan remained expressionless, but his mind was highly focused as he closely monitored the changes in his martial soul to ensure that no unexpected situations would arise.

Three days later.

All the materials had completely disappeared. Lin Chuan made a hand seal, and after the golden flames and earth fire flashed a few times, they suddenly vanished into thin air, leaving only the dark blue longbow still suspended in the air.

With a thought, the longbow slowly flew over.

I reached out and grasped it, and a strange feeling welled up inside me.

It was as if... the martial spirit in his hand had become another version of himself.

"Try it!"
