Even if he has the memory of a thousand-year-old monster, Long Chen, who is well-informed, is also a little surprised.

Alchemy is not so easy, from the environment, to the materials, to the quality of the alchemist himself, there are extremely strict requirements.

As an old grandfather of the Holy Realm who has lived for thousands of years, Long Chen is not only a martial artist, but also quite involved in other aspects, such as alchemy refining weapon formation talismans. Even his predecessor was more than a thousand years ago, when he was still in the emperor realm, he had studied alchemy for hundreds of years for some reason, and it was not difficult to get a seven-rank Danzun qualification in Danta alone.

In addition, he and Wu Danzi, the only one of the three on the mainland, were close friends, and his knowledge and insight in alchemy were not much worse than many eight-rank Dan Emperors, so he knew that alchemy was not an easy thing.

Take his friend Wu Danzi as an example, in order to refine the Lingxin Pill that made him famous in the mainland and won the title of Lingxin Pill Sage, even the current Chen Long can only be amazed.

For example, the Lingxin Pill wanted a medicinal herb Ice Heart Lotus, Wu Danzi invited Chen Long's predecessor Jia Shu to go to the extreme north together, and it took two whole years to find an eight-turn Ice Heart Lotus, originally refining the Spirit Heart Pill, the eight-turn Ice Heart Lotus was enough, but in order to increase the probability of a trace of Dancheng, Wu Danzi lived in the extremely cold place for more than half a year, constantly refining the plants with his true qi every day, during which he even asked Jia Shu to slaughter the three-headed spirit beast at the peak of the Emperor Realm to cultivate it with a spirit core, and forcibly pushed this Ice Heart Lotus to the ninth turn.

And the Ice Heart Lotus was only one of the Eight Wild main medicines needed by the Spirit Heart Pill, and later before the furnace was opened for refining, Jia Shu and another master of the Holy Realm even shot together, and set up the Zhou Tian Gathering Spirit Array, gathering the surrounding 30,000 li of spiritual energy into three zhang, just to use it to quench the impurities in the medicinal materials.

Although the Lingxin Pill is the peak of the Nine Grades of Pills, it is not the same as other low-grade pills, but it can also be seen how demanding alchemy is.

If it weren't so difficult, then everyone could be an alchemist, and an alchemist wouldn't be the most respected profession on the mainland.

And now, this little guy who is only five levels of body refining actually wants to rely on a tattered Dan furnace that even alchemist apprentices can't look down on in such a dilapidated thatched house, and a bunch of medicinal materials that add up to only a few dozen taels of silver, to refine the Dan?

Excluding the divine elixir that has long been a legend, now the elixir in the world is divided into nine grades, and the highest grade nine-grade elixir is a priceless treasure, even if it is a strong person in the holy realm, it is also flocking to it, not to mention silver taels, even if it is a high-grade spirit stone, it is not worthy of measuring the value of the nine-grade elixir.

And the lowest-level first-grade pill, what Chen Long knows is the Qi Gathering Pill, which can only assist people in the Body Refining Realm to gather Qi and cultivate, even so, if you want to refine the Qi Gathering Pill, the alchemist's cultivation must also reach the peak of the Body Refining Realm, and the value of a Qi Gathering Pill is close to a hundred taels.

Long Chen looked at Yue Mingju, who was processing medicinal herbs, and was a little curious, what kind of pill did this little guy want to refine?

Yue Ming's alchemy seems to be to treat his younger brother, Chen Long perceives it from afar, and it can be seen that Yue Mingsheng, this little guy, seems to have suffered some internal injury, his essence is greatly damaged, and his internal organs have also begun to fail, if he is not treated, he should indeed live for a short time.

Using his divine sense to sweep over the materials in Yue Ming's hand, Long Chen already had some guesses in his heart.

This little guy should want to refine Yuan Dan.

Yangyuan Dan, as the name suggests, can consolidate the foundation and cultivate the yuan, repair the wound, restore the vitality, and indeed can alleviate Yue Mingsheng's condition.

However, Yangyuan Dan is not easy to refine, although it is only a first-grade pill, but the degree of refining is even comparable to some second-grade pills.

However, compared to the difficulty of refining, the materials needed for Yangyuan Dan are relatively simple, but even so, it is not something that can be bought for dozens of taels of silver, and the materials that Yue Ming bought are if you want to refine Yangyuan Dan, I am afraid that the second-grade alchemists will also find it tricky.

Not to mention the tattered Dan furnace he used, as well as this simple environment, there was not even the most basic formation in the ordinary Dan room to prevent the loss of spiritual energy.

Even Chen Long, whose alchemy technique was equivalent to the Seven-Rank Danzun, didn't dare to say that he could successfully refine the pill under such conditions when he was refining his body fivefold.

At this time, Yue Mingju had already officially started alchemy, only to see him skillfully release the true qi from his fingertips, and manipulate the true qi with his five fingers, throwing the processed medicinal materials into the alchemy furnace one by one.

The reason why Yue Mingju was able to attract Chen Long's attention before was because of his True Qi Manipulation Ability that was obviously inconsistent with his own realm.

But even if he is extremely talented, he can manipulate the true qi so finely in the fifth level of body refining, but there is still a fatal problem.

After all, he was only refining the body fivefold, and the fine manipulation of the true qi was originally an extremely physical and true yuan thing, with his refining the fivefold true qi, it would not last long at all.

Alchemy must not be interrupted, once it is interrupted for even a moment, it will only refine a furnace of waste pills, and it is impossible to give you a chance to stop halfway to recover your true qi, you must do it in one go.

Chen Long was very curious about how this little guy was going to solve the problem of true qi.

As the medicinal herbs were thrown into the furnace one by one, Yue Mingju also began to use true qi to urge the flames, refining the herbs in the furnace and washing away the impurities.

Everyone's physique has different attributes, in addition to the basic five element attributes, there are also some special attributes, and there is the true qi of Yue Mingju, with a hint of turquoise, obviously he has the physique of the wood attribute.

And the wood is the true qi, which is the basic alchemist, among the five elements, wood makes fire, only the true qi of the wood genus can achieve the effect of fine manipulation of the danhuo, as for the fire true yuan itself is too violent, although the attack power is stronger, but it cannot achieve the fine manipulation of the wood true qi. The wood genus symbolizes vitality, and the speed of qi return and the accumulation of true yuan are higher than other attributes. Some alchemists who are vigorous in Mu Yuan can also use their own Mu Yuan to cultivate and give birth to spirit grass.

It can be said that only those who possess the true element of the wood genus have the possibility of becoming an alchemist.

This didn't surprise Long Chen, after all, if he wasn't even a wood true element, then it would be a pure dream to refine the five levels of refining the body.

And Chen Long's predecessor was born with both water and fire, but there was no wood genus True Yuan, so in the first thousand years, he never thought of the idea of being an alchemist, until he broke through the emperor realm and began to control the power of various rules, and the five elements were all connected, so that he could have the conditions to delve into alchemy.

However, although the wood genus true yuan is suitable for alchemy, the cultivation of the fifth level of refining the body is too weak after all, and sure enough, it didn't take long for beads of sweat to ooze from his forehead, and his movements were a little vain, obviously his true qi was not continuous.

The next moment, I saw him reach out and directly grab a medicinal herb next to him and stuff it into his mouth.

Chen Long raised his eyebrows, only to see that what he had eaten was a medicinal herb called Shengyuan Cao, which had the effect of restoring true qi.

This Shengyuan Grass can be used as a material for the Huiqi Pill, but it is not a material for the Yangyuan Pill, originally Chen Long was still curious about what he was doing with so many Shengyuan Grass, but he didn't expect it to be used for eating.

Shengyuan grass can indeed restore true qi, but it contains a certain amount of toxicity. It must be refined into an elixir in order to remove impurities and exert its effects.

If you eat it directly, although it also has a certain effect, it also has to bear the toxicity, which is not strong and will not be life-threatening, but it will make people's abdomen like a knife and painful, so it is also known as the small broken intestine grass.

Sure enough, not long after eating, Yue Mingju's true qi began to recover, but his face became pale, and his body trembled slightly, obviously a toxic attack, very painful.

But he endured it stubbornly, kept moving, and continued to refine the elixir.

The pain of the toxicity of the Shengyuan Grass, Chen Long's predecessor was also taught thousands of years ago, and he still remembers it vividly, this young man is only a five-fold cultivation of the body, and at the age of a teenager, he can actually endure it, and this willpower Chen Long can't help but admire.

What made Long Chen even more amazed was that this little guy's incomparably fine True Qi manipulation ability actually used this dilapidated alchemy furnace to urge the flames and slowly remove the impurities of the herbs.

Eventually, all the impurities of the herb were removed, leaving only a clear liquid that floated in the Dan furnace.

And Yue Mingju's true qi has once again reached the time of exhaustion.

Just when Long Chen thought that he was going to eat Shengyuan Grass again, he saw a trace of green light in Yue Mingju's eyes, and the blue-green True Yuan gushed out of the originally depleted dantian again, and at the same time, the toxicity of the previous Shengyuan Grass also began to be slowly dispatched.

Looking at Yue Mingju, who was covered in green light, Long Chen exclaimed in some surprise.

"Dead wood in spring, this kid turned out to be the body of Mude. ”
