After bidding farewell to Ouyang Yuyuan and Cheng Feng, Su Chen returned to the quiet alchemy room again. After refining alchemy for nearly a month, he could clearly feel that his soul power had become more solid, and the fighting energy in his body had also improved slightly. However,

It can be ignored.

In front of the medicine cauldron, Su Chen sat quietly, with the scroll in his hand spread out, and streams of information turned into streams of light and poured into his forehead and penetrated into his mind.

Some higher-grade elixirs will use this method of recording the elixir recipe. The reason is that it is naturally safer and much more convenient to store.

Su Chen knows something about this elixir. The fourth-grade peak elixir is comparable to the fifth-grade elixir. In terms of value, it far exceeds the second-layer Qingling pill, but is less expensive than the third-order Qingling pill.

It's slightly less than that.

Purple Heart Barrier-Breaking Pill, a fourth-grade pill, has the same effect as the Three Patterns Green Spirit Pill. It is also a pill that can directly enhance a person's strength. However, its effect can only be applied to the Great Fighter level.

This is also the main factor limiting this elixir.

If a person at this level takes the Purple Heart Barrier-Breaking Pill, his or her strength can be increased by one star. In addition, the most important thing is that a person at the same level can take two of these pills in succession, and

It will not produce too much resistance, that is to say, as long as you can collect two Purple Heart Barrier-Breaking Pills, you can steadily increase the two-star strength...

Su Chen also had his own idea about this so-called drug resistance, but he could not confirm this conjecture before refining it.

With a wave of his hand, about twenty jade boxes fell on the table in front of him. These are the main materials for the Purple Heart Barrier-Breaking Pill.

Su Chen glanced over.

Purple Heart Flower, Nine Immortal Hemp, Level 4 Fire Magical Beast Demonic Core, Thousand Spirit Grass, Purple Leaf Orchid Grass, Soul-breaking Fruit, Cold Root Marrow, etc.

When his eyes fell on the fire magic beast's magic core and cold root marrow, Su Chen frowned. These two medicinal materials were in conflict, and they actually appeared in a pill recipe. The most outrageous thing was that this pill

There haven't been any issues yet.

In other words, this Purple Heart Barrier-breaking Pill requires the effectiveness of these two medicinal materials.

Perhaps, the barrier-breaking power comes from the conflicting properties of these two medicines.

No longer guessing, Su Chen shook his palm lightly, and opened the lids of the boxes containing medicinal materials one by one. The medicinal materials were put into the medicine cauldron one after another. At this time, extracting what was needed was already a familiar process, and it was not just the beginning.

The jerky feeling. Those skilled movements, people who don't know it would think that he is a master of alchemy.

Three hours passed by in a flash, and Su Chen was in the middle to late stages of his first refining. He needed to fuse the potion containing the fire-attributed magic core energy of the magical beast with the cold root marrow.

Once this step is completed, the Purple Heart Barrier-Breaking Pill is not far away from being successfully refined. If it fails, it will return to before liberation overnight.

The soul power gushed out crazily from the center of Su Chen's brows, and then poured into the Xuanyou Cauldron with a strong glow, wrapping the two medicinal materials with completely opposite properties, and slowly joined together.

When ice and fire met, a burst of water mist suddenly rose from the green fire in the medicine cauldron, making it difficult to merge!

Su Chen frowned, and his soul power kept controlling the contact between the two, trying to fuse them with force. However, after a moment, his soul power controlled the two liquids to separate.

It seems that there is something missing in it.

However, Yan Li, who was no stronger than a Dou Ling, could successfully refine the Purple Heart Barrier-Breaking Pill. He didn't believe that he, a Dou King, could not compare to a Dou Ling!

Although there is no direct relationship between these.

Looking down, Su Chen saw the gray-black medicine residue discharged by the Xuanyou Cauldron. In it, he seemed to see a faint green light, which seemed to be the fusion of the magic core waste and the cold root marrow vine waste.

product.

The index finger was slightly bent, and a burst of fighting spirit rolled up the wisp of green residue and floated in front of him. There was a faint fragrance floating around.

This was most likely the neutralizing agent he was looking for. He curled his lips and stretched his brows, and the green residue was thrown into the medicine cauldron again under the coercion of fighting spirit.

The medicine residue fell into the medicine cauldron and was instantly swallowed up by the poisonous fire of the netherworld. After a violent tumbling, a force of soul fished it out and suspended it between ice and fire.

"Success or failure depends on this."

Su Chen whispered in his heart, with a decisive look in his eyes.

His hands suddenly joined together at that moment, and the three rays of light in the medicine cauldron collided together instantly. Waves of invisible fluctuations continued to spread in the medicine cauldron. Such energy impact made Xuanyou Cauldron tremble slightly, but there was no

Nothing different at all.

The quality of this Xuanyou Cauldron is really good, and it is indeed trustworthy.

Seeing that nothing happened in the medicine cauldron, the big stone hanging in Su Chen's heart finally fell, and his eyes once again fell on the three rays of light that were about to merge into one inside the medicine cauldron.

"Give it to me!"

A seal appeared between the palms, and Su Chen's low voice suddenly sounded in the quiet alchemy room.

In the medicine cauldron, there was another violent fluctuation, and the three light groups were also stuck together, the medicine blended, and a young pill appeared faintly.

With the appearance of Chu Dan, the refining of this medicine is almost completed!

In the following steps, the situation of being stagnant and overwhelmed will not happen again.

Su Chen let out a long breath of turbid air, and the flames surged up in the medicine cauldron, engulfing the light ball of the young elixir and nurturing it.

Nearly half an hour later, the figure tapped his fingers on the top of the medicinal cauldron, opened the top cover, and a purple elixir fragrance that was so rich that it turned into substance flowed out of the medicinal cauldron, and a purple stream of light sprang out from the elixir incense, and finally fell on it.

In his hands.

Su Chen stared at the purple elixir with a strong fragrance in his hand with a smile. This first refining was successful.

The peak level 4 pills are so difficult to refine. What about the higher level 5, 6, or even 7 and 8 levels?

How difficult would it be to refine it like that?

He held his hands lightly and stared at the elixir with his eyes. In his perception, there seemed to be a wisp of hazy black smoke in the elixir, but it was difficult to catch it.

What is this?

Feeling the darkness in it, Su Chen frowned slightly, it didn't look like a good thing. He clenched his palm suddenly, and a ball of fire suddenly appeared, covering the elixir and burning it repeatedly.

After calcination for a long time, a faint black mist slowly rose from the fire ball glowing with green light.

Su Chen raised his other hand, and when he was about to retract the elixir, he grabbed the black mist and put it directly into his mouth.

When the poisonous gas entered his mouth, his breath rose an inch higher. At this moment, he was sure that this thing was poison! Perhaps this was the reason why this type of elixir had a limit on the number of times it could be taken.

Su Chen called it erysipelas!

According to Su Chen's guess, this so-called erysipelas will be more or less present in the Douling Pill and Huangji Pill, and if these erysipelas are taken out of the pill, the so-called quantity limit will also follow.

was broken.

This step is very simple for Su Chen.

Others may be able to discover and remove the erysipelas, but they are unable to solve it and naturally let it return to the elixir. However, Su Chen can solve this hidden danger.

Looking at the purple elixir in his hand with satisfaction, Su Chen took out a jade bottle, stuffed it into it, and placed it on the table aside.

These elixirs will be given to Ling Hua later to test the poison. Anyway, the ingredients for these elixirs are all taken from the warehouse of Wandu Sect. The elixirs will not be a loss if they are spent on the future disciple of the sect leader.
