Dan Cheng!

Fire Attribute: Used to control flames and refine medicinal herbs.

Wood Attribute: Sensed medicinal properties, harmonized medicinal power, and stimulated medicinal power.

Spiritual Power: Precisely controlled the alchemy process.

Based on the pill-refining process from Battle Through the Heavens.

Li Fei had developed an alchemy technique of his own.

After attempting countless deductions in his mind.

He opened his eyes, and a flash of inspiration struck him.

He already had a clue.

"Let's give it a try."

Li Fei took out a batch of medicinal herbs.

He did not use Whale Rubber.

He had bought so many medicinal herbs at once precisely to leave himself more room for error.

Of course, completing it in one attempt would naturally be best.

He had already mastered both the Fire Attribute and Wood Attribute to an extremely high level.

With his Heaven-Defying Comprehension, his Spiritual Power would not be lacking either.

As for the pill furnace needed for alchemy.

That was easy enough.

He mobilized Earth Element Energy and used the Earth Construction Technique.

Soil rose from the ground and, under his control, gradually formed into a pill furnace one meter wide and half a meter tall.

He then reinforced it with the Gold Attribute, which would also allow it to conduct heat better.

At the same time, he injected the other three elements—fire, wood, and water—into the barrier walls.

This gave the furnace a balance of the Five Elements.

Inside the furnace was a black-and-white Taiji Diagram.

A simple Yin Yang Five Elements Alchemy Furnace was complete.

"Begin!"

Next, Li Fei tossed the medicinal herbs inside.

At the same time, he activated Flame Force to melt them at high temperatures.

He also wrapped them in the Wood Attribute.

With the support of Yin Yang Force, Five Elements Power, and Heaven-Defying Luck.

After roughly ten minutes, all the medicinal herbs had melted into liquid.

The Wood Attribute activated, beginning to sense the medicinal power, harmonize it, and stimulate it.

His Spiritual Power also began to seep inside, precisely controlling the process.

This was an extremely crucial step.

He needed to remove the bad portions and retain only the good ones.

This step consumed a great deal of time, energy, and concentration.

One mistake, and the alchemy would fail.

Because he was so focused, hot sweat had already formed on Li Fei's forehead.

However, hard work paid off.

As time passed.

Li Fei finally completed the separation smoothly, leaving behind only the good parts.

However, there was very little of it, and this was when the Wood Attribute's ability to stimulate medicinal power was needed.

This process was also rather lengthy.

It could not be rushed.

During this process, Li Fei activated his Soul Power and increased the Wood Attribute Soul Power output, gradually shortening the long process bit by bit.

As time passed, that tiny amount of liquid slowly increased.

Flames scorched it from the outside while the Wood Attribute enveloped it within.

The surrounding Five Elements Power and Yin Yang Force also revolved.

Drop after drop of medicinal liquid gradually took on the liquid shape of round pills.

Having reached this stage, the pill prototypes were complete.

All that remained was to wait calmly for them to fully solidify into pills.

Another half hour passed.

The flames dispersed, leaving only blue elixirs wrapped in Wood Element Energy, resting quietly within the furnace's Taiji Diagram.

There were ten in total.

One batch of medicinal herbs, his first attempt at alchemy, and he had actually produced ten pills in a single furnace!

Even Li Fei found this surprising.

Although he had conducted countless mental deductions, this was his first real attempt.

He had not expected the result to exceed his expectations.

"Whew, it's finally done."

"Looks like Heaven-Defying Luck played a part in this too. Otherwise, it couldn't have gone so smoothly."

Although these two cheats were not active abilities and only worked passively, they had still given me tremendous help.

Li Fei let out a breath of Turbid Air, withdrew his Spiritual Power, and felt somewhat exhausted.

His forehead and face were covered in hot sweat.

His complexion was also somewhat pale.

This was caused by excessive Spiritual Power consumption.

Soul Power consumption was secondary.

After all, the Yin Yang Soul Core was like a power bank and could replenish it in time.

But there was no Spiritual Soul Core to replenish Spiritual Power.

"Perfect. I can keep using the Wood Attribute to nourish them and make the pills even better."

Li Fei looked at the ten blue elixirs in the furnace, filled with a sense of accomplishment. Finally, he closed his eyes and circulated the Willow God Method, entering meditation to restore his Spiritual Power and Soul Power.

When he opened his eyes again, it was already the next morning.

He had completely replenished his depleted Spiritual Power and Soul Power.

He had returned to his peak condition!

He sniffed the air.

An incredibly pleasant Pill Fragrance had already filled the entire Mongolian Yurt.

The Mongolian Yurt had been designed with insulation in mind, so the Pill Fragrance had not spread outside.

As for how air entered, one should not forget that the Ambrosial Arbor was alive and could provide air through photosynthesis and plant respiration.

Naturally, there would be no absurd situation where he died from a lack of oxygen.

He looked at the ten pills inside the furnace.

The Wood Attribute light had vanished, leaving only ten smooth, round pills overflowing with Pill Fragrance.

He reached out and took them all. There was no heat left on the pills; they were at room temperature.

Judging from their color, fragrance, and smooth, rounded appearance, the quality of these ten pills was definitely not low.

He just did not know how effective they were.

As for what grade of pills they were, Li Fei had no way to judge.

The Breaking Clan had not classified pills into grades either.

He picked one up and put it into his mouth, just about to taste it.

The next second, the pill turned into a stream of pure energy and entered his body through his throat.

So this was what it meant for a pill to melt upon entering the mouth. There was no way to taste it properly.

Immediately afterward, potent medicinal power began to spread from within his body.

Li Fei did not dare slack off. He immediately circulated the Willow God Method, guiding the medicinal power into his internal organs, Extraordinary Meridians, Bones, blood vessels, skin, flesh, and every other internal and external part of his body.

Everywhere it passed, he could clearly sense his body being strengthened.

To absorb Soul Rings below ten thousand years, one merely needed to withstand the Soul Power's impact on the body.

As long as the body was strong enough, one could absorb four 9,999-year Soul Rings before becoming a Soul King.

This would raise both Soul Power strength and Soul Power Level to their utmost limits.

However, that required being nurtured with tonics starting from the fetal stage.

Clearly, 99.99 percent of the people on the Douluo Continent could not accomplish that.

Even Li Fei could not.

However, he could try it with his Third Soul Ring and Fourth Soul Ring.

If Whale Rubber was added, perhaps he could absorb a Ten Thousand Year Soul Beast as his Third Soul Ring.

Of course, that was only speculation.

Based on how much this pill had strengthened his body, it had raised his Soul Ring absorption age limit by at least several decades.

"There won't be any truly good medicinal herbs here. I'll still have to search for them in the Soul Beast Forest myself. After all, the people at medicinal herb shops don't know enough."

While waiting at the medicinal herb shop, Li Fei had observed the names of the herbs in the cabinets. They had all been quite common.

The list he had written down also contained herbs commonly available on the market.

Their ages would not be very high either.

For genuinely good, high-age medicinal herbs, he would have to find them himself.

"The advantage of the Douluo Continent is that high-age medicinal herbs are not scarce here. Hundred-year, thousand-year, ten-thousand-year, and even hundred-thousand-year Soul Beasts can all serve as excellent high-age medicinal herbs for my alchemy."

Li Fei thought to himself.

He began trying a second pill.

However, its effect was nowhere near as great as the first one.

It only raised his limit by around ten years.

He guessed that the medicinal power of the first pill had not been fully absorbed yet, so the second pill's effect did not overlap much.

Or perhaps the cells and Genes in his body had already adapted to the first pill.

The more pills of the same type he consumed, the weaker their effects would become.

So he continued with a third pill.

Sure enough, this time it only raised it by five years.

The fourth pill raised it by two and a half years.

The fifth pill raised it by around one year.

The sixth pill's effect was negligible.

The seventh pill no longer had any effect.
