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

"External soul bone!"

Lin Chuan's eyes widened, his face showing surprise and joy.

Unexpectedly, he was so lucky that he not only obtained a soul bone, but also the rarest external soul bone. Fortunately, he did not forget to take the corpse of the Dark Gold Terrorclaw Bear with him when he left, otherwise he would have really missed it.

This comes from the Dark Gold Terrorclaw Bear, and the most powerful thing about this soul beast is its pair of giant claws with terrifying attack power.

The power of an external soul bone with nearly 20,000 years of cultivation is unimaginable.

"Tsk, so we can also experience the treatment Huo Gua received?"

Lin Chuan chuckled, then calmed down and fell into deep thought.

The external soul bone will definitely grant you a powerful soul skill, and it can even evolve continuously. It's really tempting!

If it were to undergo further refinement by the Azure Veined Cauldron...

"Hiss, my god, doesn't that mean he'd have to split the heavens in two with a single claw?!"

Lin Chuan gasped, his gaze burning with desire, but he forced himself to suppress his inner urges and did not immediately absorb the dark gold dinosaur claw bear's right palm bone.

Just as he thought, it would be best to absorb it after the spirit has been refined.

Lin Chuan had already made attempts after successfully nurturing the Golden Flame Earth Fire.

Ordinary fire can undergo one spirit refinement, but Golden Flame Earth Fire can undergo two. According to the information recorded in the "Alchemy Manual", Earth Fire can improve its quality through nurturing. Currently, Lin Chuan's Golden Flame Earth Fire has not even reached the grade level.

If the quality of the Golden Flame Earth Fire improves, will it increase the number of times the Spirit Refining is required?

Once the soul bone is absorbed, it cannot be retrieved. The intensity of two or three soul refinements is obviously different, so Lin Chuan decided to wait a little longer.

After improving the quality of the Golden Flame Earth Fire and testing it, then absorb the right palm bone in front of you.

"Phew... coming to Sunset Forest to hunt souls was definitely the wisest decision I ever made!"

Chapter 67 Earth Dragon Golden Melon, Earth Dragon Pill

Dugu Bo was very efficient and soon brought back a batch of medicinal herbs.

Lin Chuan found a secluded cave and began refining medicine.

In the days that followed, his daily routine became almost fixed. He would refine medicine every day until his soul power or spirit could no longer withstand it, at which point he would stop to meditate and cultivate.

In his spare time, he did not forget to practice archery and swordsmanship.

Under such intense practice, Lin Chuan's alchemy skills improved by leaps and bounds, and all the medicinal herbs that were delivered to him were transformed into pills in his hands.

Examples include Blood-Activating Powder for treating external injuries, Rejuvenating Pill for treating internal injuries, Strength-Boosting Pill for temporarily increasing power, Qi-Replenishing Pill for restoring soul power, and Ice Heart Pill for assisting cultivation, etc.

Their effects vary, yet their scope is quite broad.

After the Shui family made preparations, these pills began to appear on the market on a small scale, and in a very short time, they caused a sensation.

It was almost exactly as Lin Chuan had predicted.

Thanks to this, he had more materials to use to accumulate experience.

Time flies, and several months have passed in the blink of an eye.

Lin Chuan has now officially become a third-grade alchemist, capable of refining some third-grade pills, although the success rate and pill-making rate are not as high as those of second-grade pills.

Even so, they are already able to handle more advanced elixir formulas.

Inside the Yin-Yang Eye of Ice and Fire.

Lin Chuan sat cross-legged in the cave, swallowed an Ice Heart Pill, and began to close his eyes and regulate his breathing. His mind became clear and he quickly entered a meditative state.

To avoid disturbing Lin Chuan, Dugu Bo took the initiative to leave and waited outside the Ice and Fire Yin-Yang Well.

"Young Lin, you mustn't let this old man down!"

Having spent so much time together, Dugu Bo had great faith in Lin Chuan's abilities. However, there was only one set of materials, and if anything went wrong, everything would be lost.

Even though Dugu Bo prided himself on his exceptional composure, he was still somewhat uneasy at this moment.

Half an hour later, Lin Chuan slowly opened his eyes.

"let's start!"

Only after adjusting himself to his optimal state did he take out his medicine cauldron.

This medicine cauldron was bought in Gengxin City. It can only be considered a beginner's medicine cauldron. However, since not many people in Douluo Continent know how to prepare medicine, its quality is not very good.

Fortunately, after two rounds of spirit refining, its quality has improved considerably.

Currently, it can be used at the level of a third-grade alchemist.

After all, when refining fourth-grade pills, one must draw a great deal of energy from the outside world. If the cauldron is not up to standard, it may be destroyed by the violent energy.

It's a pity that the Azure Patterned Cauldron can't be used for refining medicine; otherwise, there would be no need for such trouble.

"call!"

Lin Chuan raised his hand and summoned the Golden Flame Earth Fire, pouring it into the medicine cauldron. He then used his soul power to heat it up, while controlling the flame to rotate within the cauldron, ensuring that the entire cauldron was preheated evenly.

After the preparations were completed, the medicinal herbs were thrown into the cauldron one by one for extraction.

These steps have been performed countless times, and with increasing skill in controlling the fire, and with a thorough understanding of the properties of the medicinal materials, the risk of burning is almost nonexistent.

The whole process was carried out in an orderly manner, and the essence of the medicinal herbs was extracted one after another.

In particular, the earthworm and golden melon, which are the main ingredients, have now turned into a golden medicinal liquid, and the whole cave can smell the rich medicinal fragrance.

What Lin Chuan was going to refine was a grade three elixir called the Earth Dragon Pill.

Although the Earth Dragon Golden Melon is an earth-attribute medicinal herb, it contains the bloodline of the dragon race. Therefore, after consuming the Earth Dragon Pill, one will obtain the bloodline of the dragon race, greatly improve their physical fitness, enhance their earth element talent, and even increase their cultivation level.

The dragon bloodline within is highly beneficial even for dragon-type martial souls, let alone snake-type martial souls.

Now that the medicinal materials have been extracted, the next step is to condense and form the pill.

Lin Chuan took a deep breath, controlling the flames with one hand while using the other to put the extracted medicinal essence into the cauldron in batches.

With his mind highly focused, he constantly changed the hand seals for controlling fire.

The golden flames gradually differentiated and began to change color, sometimes bursting with golden light, sometimes shimmering with orange-yellow, and some turning crimson.

Under the control of mental power, the essence of various medicines began to gradually merge.

Lin Chuan stared intently at the fluid in the subterranean fire. After about fifteen minutes, the fluid gradually stabilized, its volume gradually decreased, and it eventually formed a sphere.

"It's now!"

Lin Chuan's fire-controlling hand seals changed continuously, controlling the golden flame earth fire to rotate rapidly around the pill.

The flames flickered and the temperature fluctuated. In this alternation, the medicinal properties of the pill were fully integrated, and at the same time, it slowly differentiated from a single whole into many individual parts.

The energy of heaven and earth also began to flow into the medicine cauldron, making the pills inside even more round and full.

This is a transformation towards a complete elixir!

"Congeal!"

As the last hand seal was completed, the medicine cauldron emitted a bright light.

As the flames subsided, three golden pills lay quietly in the cauldron, their outer shells still warm, wisps of smoke rising from them.

"It's done!"

Lin Chuan's face lit up with joy. He moved with lightning speed, taking the three pills into his palm and examining them carefully.

The longan-sized fruit, with its round shape and golden color, is already quite good. It's just a pity that it doesn't have any red veins; otherwise, both its quality and effect would be even better.

Earth Dragon Pill is one of the more difficult pills to refine among the third-grade pills. With Lin Chuan's current level, it's still too early for him to refine an Earth Dragon Pill with pill patterns.

"It went fairly smoothly, and thankfully there was no failure. Moreover, the earth dragon golden melon was even more effective than I had imagined. The medicinal power contained within it was able to condense into three pills, one more than I expected."

"However, if I can't refine pill patterns, I can create them artificially!"

Lin Chuan waved his hand to put away the medicine cauldron, and a beam of green light shot out from between his eyebrows. The green-patterned cauldron landed steadily.

Immediately afterwards, the Earth Dragon Pill was placed into the cauldron.

With a flick of his finger, the golden flames of earth fire instantly fell beneath the azure-patterned cauldron.

About three breaths later, the first inscription on the Azure Patterned Cauldron lit up, and as the silvery-white light flickered, the energy of heaven and earth began to flow into the Earth Dragon Pill.

Immediately afterwards, the second inscription lit up as well.

The two inscriptions simultaneously shone with a silvery-white light. Visible to the naked eye, a silvery-white halo far exceeding that of a single spirit refinement enveloped the Azure Pattern Cauldron, with countless silver light particles jumping up and down like fireflies.

At the same time, the energy of heaven and earth began to be extracted in large quantities.

However, the Yin-Yang Eye of Ice and Fire is special, with abundant spiritual energy from heaven and earth, and is fully capable of withstanding this level of absorption.

Finally, the silver inscriptions on the Azure Patterned Cauldron gradually dimmed, and it stopped absorbing the energy of heaven and earth, which also indicated the end of the spirit refining process.

Astonishing energy fluctuations reverberated around the Earth Dragon Pill.

"It's a pity that it couldn't be upgraded in grade, but its medicinal power has been greatly improved, even slightly better than high-quality pills with pill patterns. Did it remove impurities and increase its medicinal properties?"

Lin Chuan silently guessed what was going on, but didn't dwell on it too much.
