Hua Ling San is not the kind of medicine powder that traditionally improves cultivation, but a combat medicine powder with extremely strong and debilitating properties.

When thrown by the enemy, if the spirit dispersion is contaminated on the surface of the body, it will have a strong burning effect, which is fatal to the cultivators of the Nayuan Realm.

Because burning the skin can also cause the spiritual power to decay rapidly!

For a cultivator in the Nayuan Realm, not being able to use spiritual power to fight is tantamount to scrapping his arms, and his combat power will be greatly reduced.

Nowadays, the Xu family is like an island, seemingly huge, but in fact there is no one to help them.

All the families in Wangcheng are resentful, and the time they are away is destined to be full of conflicts.

Xu Cang is also left behind, a bottle of spirit dispersion is enough to fight against all the Nayuan Realm masters of the Wangcheng family, everything depends on how the Seven Elders use it.

Overall, he is still relatively relieved.

This time, they planned to take a merchant ship to the national capital, and the cost was basically negligible.

After all, Qin Zhaoxue still has more than 10 million silver tickets in her possession.

This kind of value background, even when you go to the Xuanyu country, you can walk unimpeded, and you can live a chic and happy life for a long time.

The three of them boarded a merchant ship.

Boats sail on the canal, rippling and rippling.

Standing on the deck and looking out from afar, Xu Cang had a lot of thoughts.

There are two important things to do on this trip to Xuanyu Kingdom.

First: Contact the forbidden Tianjiao of the National Capital Academy, kill and devour its system.

Second: Seek revenge on the king.

The king of a country is certainly powerful, but he can't tolerate the cruelty of Xu Can's family.

Even the forces that oppose the entire Xuanyu Kingdom are not afraid.

Besides, as soon as the old man broke through the realm of the law phase, he couldn't wait to kill Xiang Guodu, and he didn't know what the current situation was.

In any case, he was going to find out, for the sake of the old man's safety.

They leave early in the morning, and the morning breeze blows on their faces to give them a cool feeling.

Qin Zhaoxue came quietly: "Childe, the big black cauldron you asked me to prepare before has been brought, is it going to start now?"

Xu Cang's head.

After obtaining permission from the shipowner, he set up a large black cauldron with a radius of one meter, and many medicinal herbs were placed next to it.

These are the ones that Hessewind had gone out to collect yesterday.

At this moment, Xu Cang calmed down and took out a purple spirit stone from his arms.

Lighting a fire under the black cauldron, Xu Cang used his spiritual power to crush the spirit stone in his hand into powder and throw it into the Tengteng fire.

In the blink of an eye, the flame that was still red changed color and became a purple flame, which looked very special.

Qin Zhaoxue and Hexifeng were both present, this was requested by Xu Cang, let the two observe, although they have not made progress in cultivation, but they need to learn more and see more to increase their experience.

At this moment, when the two of them saw the color of the flame from red to purple, they couldn't help but jump in their hearts.

There is still purple fire in the sky, but is there anything surprising about this?

Xu Cang expected the surprise of the two, and patiently taught: "During the Hongmeng Open Heaven period, there was only a cluster of void fire in the world, formless and colorless, burning everything in the world, destroying all living beings, and even burning most of the sky to ashes. ”

"This incident disturbed the remnant soul of the Great God of the Open Heavens, and it was only with the Great Divine Power that this Void Fire Seal was imprisoned, but the remaining strength was insufficient, and it was difficult to completely erase it. Therefore, this fire was weakened and decomposed into ten thousand flames, and a supernatural spell was placed on each flame, so that ten thousand flames lost their original powerful power over the years, and their power was gradually diluted. ”

"The Purple Heart Fire you see in front of you is one of the Ten Thousand Flames, ranking at 9,830. ”

After hearing this, the two couldn't help but gasp.

They had never heard of such a secret, and in fact, there were not many people in the world who knew about it, and most of them were the core figures of the Great Sect.

It was only through the fragmentary codex left over from antiquity that I learned such a secret.

Qin Zhaoxue and Hexifeng are also lucky to learn such an amazing truth today.

There are still 10,000 kinds of flames in the world, all of which are stripped out of the Void Ancestral Fire!

The purple heart fire they saw in front of them, ranked 9,830, belonged to the existence of the tail of the crane.

But what's going on with this fiery feeling?

Both of them were retreating, their faces were roasted hot, extremely uncomfortable, as if the purple heart fire was baked on their faces, which was unbearable.

Qin Zhaoxue awakened the delicate snow lotus in her body, keeping it half-open and half-closed, and her body temperature was barely controlled at a constant temperature.

Hessey needs to retreat seven or eight meters, which is a little better.

"The generation of the Purple Heart Fire is very simple, only one spirit stone is needed to burn, usually we use it for alchemy, its temperature is much higher than that of ordinary open flames, and it can melt many medicinal herbs and elixirs that cannot be melted by open flames. ”

Xu Cang's mouth kept talking, and he threw the medicinal herbs on his side into the big black cauldron one by one.

Hewangcheng Temple is small, and under the scarcity of alchemists, there is naturally no alchemy furnace circulating in the market.

Because even if there is, no one buys it.

So Xu Cang simply asked Qin Zhaoxue to bring the big black pot for cooking rice directly in the stove workshop.

Used to act as an alchemy furnace!

I have to say that the material of this pot is very special, and it can withstand the extremely high temperature of the purple heart fire, Xu Cang is a little curious.

But he was busy with alchemy, and he didn't explore too much.

One medicinal herb after another is put into the pot, and it is melted into a puddle of sticky things under the high temperature of the purple heart fire, which is the essence of the medicinal herbs.

Seeing that the fire was almost over, Xu Cang raised his hand again, and this time what he threw into it was a spirit grass that was like a sword as a whole.

He also went out to buy yesterday and bought back a lot of spiritual herbs that could be used as the main medicine.

Time passed, and when Qin Zhaoxue and the others finally witnessed Xu Cang harvesting juice into pills, they were all a little excited.

Smelling this extremely rich aroma, the two of them wanted to swallow it immediately, as if the elixir in Xu Can's hand was inherently extremely tempting to them.

"This is a Nayuan Dan, you take it first. Xu Cang threw the pill to Hexifeng at will, and said, "After arriving in the national capital, I may not teach you to practice again, but I will first refine some pills to assist in cultivation in the next few days to ensure that your cultivation is diligent." ”

Hessey is like a treasure, and the boss with a grin on the corners of his mouth.

"Master, you can refine the Nayuan Dan, doesn't it mean that you are a yellow-rank alchemist who has obtained the jade slip of the red bronze qualification?"

His eyes were full of admiration, and the teachers in the academy who were responsible for teaching alchemy were all only senior apprentices of Dan Dao.

But I didn't expect Xu Cang to be a yellow-level alchemist, and the gap widened all of a sudden.

So what else to learn?

It is better to follow Xu Cang, the great demon king, to study the Dan Dao in the future, and he will definitely have extremely high achievements in this area in the future.

It's ridiculous that I took it for granted that the master I was on the stall was a half-ass.

Allowing yourself to procure medicinal herbs is just to be able to become a Dan Dao apprentice.
