With the accumulation of Ding Yi's knowledge, his strength has been continuously improved. His thinking is getting closer and closer to reality. Because more and more elements are considered, the time spent is getting longer and longer.

It took five or six minutes before Ding Yi opened his eyes.

Nangong Li was a little curious, what was the meaning of Xu Hui Fangcai's closed eyes and contemplation. She vaguely felt that maybe this was the key to Xu Hui's cracking of the Danfang. Could it be that Ding Yi can still optimize the Dan Fang of the Little Five Elements Pill? Nangong Li was inexplicably excited.

Seeing Nangong Li staring at him, Ding Yi was a little embarrassed.

"Fang was a little distracted, but it made my senior sister smile, let's start. ”

Ding Yi didn't explain the reason why he just closed his eyes, and the fire of Nangong Li's gossip was blazing, but Ding Yi didn't want to say it, and she didn't want to ask again.

"The gold of the five elements, the five elements of gold, Xuanjin, blue iron, fire copper, gray lead, mercury......" Nangong Li explained to Ding Yi the treatment of the gold of the five elements.

It is not easy to grind into powder because it is extremely hard and requires some special tools.

Green iron is rich in impurities, which need to be repeatedly forged at a high temperature of more than 700 degrees Celsius, and after removing impurities, it must also be ground.

......

The 'gold' of the Little Five Elements Pill, just these five metals, have to be processed for two or three days, which is an extremely test of people's endurance and physical strength.

"Wait!" stopped Nangong Li's demonstration again.

Ding Yi took a small tripod from the tripod frame, and Ding Yi first chopped the gold nugget into a small piece and a small piece with an axe, and then threw the gold nugget into the tripod.

Light a Dan furnace, set it to a temperature of about 700 degrees, and put the Danding on it.

"There are many protrusions in the interior of this small tripod, which is a rotating tripod, which can rotate at a uniform speed and automatically grind the gold. We don't have to worry about it, after about six or seven hours, we can get the Xuanjin powder. ”

"It's just that there may still be impurities in this powder, so it has to be soaked in white vinegar for five or six hours, and finally drained and roasted again. Senior sister, don't worry, my method is much better than your hard work, the key is to leave everything to the machine, what do you say?" Ding Yi explained to Nangong Li while operating.

It can be explained in a logical way, but it feels a little weird.

This Xu Hui is really eclectic, and his style of acting is different from others.

For the other four golds, Ding Yi also used unusual methods to deal with them.

Or calcining, or soaking, or using some chemical methods to extract, anyway, it is a method that Nangong Li has never thought of and used.

"Senior sister, the operation of the gold of the five elements, to put it bluntly, is to purify and refine, understand this truth, this operation is much simpler, such as this green iron, why do you have to operate like this? What is its principle? What is the purpose? Is there a better way? Senior sister, you only need to think that the same purification and processing of each material, this procedure is much simpler. ”

"The purification of green iron, in fact, has a simple and easy method, the first step is grinding, the second step is calcination, the third step is to soak it in white vinegar, the fourth step is to calcinate again, the fifth step is magnetic, and the sixth step is to screen ......."

This little Five Elements Pill, Nangong Li has also refined it more than a dozen times, although the success rate is not high, but this is the master's word of mouth, personally guided, the master taught her this little Five Elements Pill, but there is no such careful explanation as Xu Hui.

Maybe her master doesn't really understand the true meaning of many procedures, but just repeats the teachings of his own master, passed down from generation to generation.

This is the charm of Xu Hui, he is a person who has truly comprehended the knowledge of pharmacology. He has a strong thirst for knowledge and curiosity, and he uses an attitude of criticism and skepticism to learn all kinds of knowledge, rather than blindly accepting it, swallowing dates, and not seeking to understand everything.

Nangong Li had no doubt that this was Ding Yi's first time refining the Little Five Elements Pill, and everything Ding Yi said and did made sense. Nangong Li was originally going to teach him refining, but now it turned out to be the other way around, and it became Ding Yi teaching her.

The purification of each kind of 'gold gold' is different, and the loss of each kind of 'gold gold' is not the same, so this ratio will still change. Nangong Li didn't expect that Ding Yi would even notice this. She now had no doubt that the Dragon Essence Pill had been realized by himself.

Originally, I thought it would be a very laborious job, but it was simplified. Nangong Li didn't know if it was right to do this. However, Ding Yi's reasoning is very thorough and reasonable, and she can't even refute it.

The whole operation has become Ding Yi in the lead, watching him concentrate on his work, listening to him tell the principle of each process, at this moment Xu Hui's image has long surpassed any genius in the Tiandaomen that she once admired, and only Xu Hui can afford the title of 'genius' at this moment.

All afternoon, Nangong Li and Ding Yi were refining the 'golden gold'. This is the most time-consuming preparation in the Little Five Elements Dan. Nangong Li originally thought that it would take two or three days to complete. Now it seems that the work can be finished in the evening, and the labor intensity is greatly reduced.

In the evening, Nangong Li cooked the meal, which she did by herself, and she never realized that cooking was actually so interesting. This was something she used to hate. She especially liked to see Xu Hui munching on her cooking and hearing him compliment herself.

Nangong Li was very satisfied with such a scene, and the joy in her heart was beyond words.

"Yo, I'm eating. A voice came out extremely discordantly, Nangong Li's expression changed greatly, and all her attention was on Xu Hui, she was bullied into her side, so close, she came to her senses.

A beautiful woman in a black skirt slowly descended from the sky with Wang Yonggang.

Is this the female Rakshasa Zhu Can? I can't imagine that she is so beautiful. Ding Yi secretly gave this female Rakshasa a high score.

Mu Yanran's beauty is a kind of national color and heavenly fragrance, Ren Tianqing's beauty is a kind of cold beauty of proud snow and cold plums, and this female Rakshasa is a kind of soul-seducing evil charm. This is one of the more distinctive women Ding Yi has ever seen. He looked at the female rakshasa who fell from the sky, and a smile appeared on his face.

"Zhu Can!" Nangong Li recognized the woman in front of her at a glance.

"This is Bamboo Garden, my Nangong Li's territory, you are not welcome here, please leave!"

Nangong Li, like a female tiger with strength, flashed with a dangerous cold glint in her eyes. The body is slightly bowed, and it is obvious that it has entered a state of high alert.

"Oh! the people of the Nangong family are interesting!" Zhu Can's Danfeng eyes narrowed slightly, and his eyes were as sharp as the tip of a needle, shooting straight at Nangong Li.

"Zhu Can, what do you want to do here? This is Rong Dingfeng, believe it or not, I can call thousands of people to beat you up in a minute!" Nangong Li said intimidatingly.

Nangong Li is not a martial arts master, a hundred Nangong Li will not be Zhu Can's opponents, and in the face of Zhu Can, she has no chance of winning.

Zhu Can took two steps forward, while Nangong Li retreated to the other side of the table and allowed to return to that side. Nangong Li opened her arms to protect Ding Yi.

Nangong Li said to Ding Yi in a barely audible voice: "Xu Hui, you leave quickly, how far is it, how far do you run......" Even at this moment, Nangong Li was still worried about Ding Yi's safety, which made Ding Yi a little moved.

However, this Zhu Can was invited by him, so he naturally had no reason to escape.

Zhu Can found that Nangong Li's strength was low, and she dissipated some of her anger, she glanced at Nangong Li coldly, and looked at Ding Yi behind Nangong Li.

"Are you Xu Hui?" Zhu Can frowned, and she glanced sideways at Wang Yonggang she had brought back. This fool said that Rong Dingfeng's Xu Hui was able to repair her love sword, so that she rushed all the way over, but she didn't expect this Xu Hui to be just a teenager, a feeling of being deceived, spontaneously, those who dare to deceive her Zhu Can can only die!

Her violent aura began to rise, she was a sword cultivator, and her love sword was broken, but even if she didn't have a sword in her hand, just these two or three people in front of her, she was confident that she could cut them off in minutes.

"Did you bring your sword?" Ding Yi asked loudly without any fear.

Zhu Can was about to break out and hurt people, but was stunned by Ding Yi's words.

Nangong Li felt a little inexplicable.

Ding Yi frowned and said again: "If you don't want to fix it, please leave." ”

Zhu Can has never seen such an arrogant young man, but thinking that this young man took the initiative to contact him, with his own reputation, there is no reason for this young man to make unwise moves. She was a little skeptical.

From the storage bracelet, she took out the love sword that was broken into three.

Ding Yi said to Nangong Li at this time: "Senior sister, you go back first, I still have work at night......"

Where is Nangong Li, this is a female Rakshasa, one of the most unreasonable people in the Heavenly Dao Gate, although she still doesn't know what Ding Yi meant by what he said to the female Rakshasa . Regardless of her identity as the owner of the bamboo garden or her feelings for Ding Yi, she has no intention of leaving.

"Xu Hui, she is Zhu Can, the most domineering and unreasonable person in Tiandaomen, you ......" Nangong Li did not give an inch, guarding Ding Yi to the death.

"She's a guest I invited, helping her repair the sword is my job tonight, how can I work if you stop me like this?" Ding Yi patiently persuaded.

"Nangong family, don't make trouble for me, provoke my aunt's heart to be on fire, and burn your Rong Dingfeng. Zhu Can threatened.

"If you burn it, you will only bully the weak, you are so powerful, why don't you go to the winger brother who broke your sword to be murderous?" Nangong Li's martial arts kung fu is not as good as Zhu Can, but her lip kung fu will not lose to her.

"If you dare to talk nonsense again, believe it or not, I'll tear your mouth apart!" Zhu Can said angrily.

Ding Yi said: "This is not a place to quarrel, Senior Sister, you have to believe me, you two don't quarrel, Senior Sister Zhu Can, you have a request for others, this is not the attitude you should have, right?"

Nangong Li still wanted to stop her, but Ding Yi had already bypassed her.

"Senior Sister Zhu Can has come all the way, have you eaten?" Yonggang, go to the kitchen and get a pair of clean dishes and chopsticks to come out......" Ding Yi glanced at Wang Yonggang.

"What to eat, the food I cook, even if it is fed to the dogs, will not be eaten by the people of the Zhu family!" Nangong Li pretended to be a lady for so long, and this time it was completely revealed, and she directly flipped the table.

"Little hoof, my aunt has wanted to teach you a lesson for a long time. Zhu Can was furious, and raising his hand was a shuriken, this is the method of releasing sword qi, which can condense spiritual energy into a sword, and it is extremely powerful.

Nangong Li is close to Zhu Can, if this shuriken hits Nangong Li, I am afraid that immediately, the owner of the bamboo garden will die. said that it was too late, it was too fast, and I saw that the same sword light was obliquely catching up, and took this fierce killing move.

Zhu Can sent out this shuriken, and she regretted it, Nangong Li was not an ordinary inner disciple, she was the true disciple of Rong Dingfeng. In someone else's territory, killing the other party's true disciple is a big crime in the Heavenly Dao Gate, even if Zhu Can is an elite disciple, this sin will not be small. In the team of stone mining in Mangju Mountain, there may be a place for themselves.

Nangong Li had already lost her face at this time, and she had just walked around on the edge of death, if it wasn't for Xu Hui to help block this, she would probably be pierced through the heart by the crazy woman in front of her.

Nangong Li was so frightened that she couldn't speak for a while. Zhu Can narrowed his eyes and carefully looked at the young man opposite. Just now. She clearly saw that the young man was using his sword qi to block her shuriken.

"It turns out that you are still a swordsman!" Zhu Can said slowly, she looked at the young man opposite with a solemn expression.

"Don't mess around, don't forget what you're here for, do you want to repair your sword?" asked Ding Yi. At that moment, he used the method of four or two thousand catties to crack Zhu Can's sword qi, if this Zhu Can made a mistake, he didn't have the ability to release the second sword qi again, just now, his spiritual power had been exhausted.

Zhu Can was dumbfounded for a while.

Zhu Can's strength should be the same level as Ren Tianqing, Ding Yi can barely last two or three rounds under them without the help of puppetry, after all, he has received strict training in this area, but this is very different in the eyes of Zhu Can and Nangong Li.

Although Nangong Li is a little spicy, she is not as crazy as Zhu Can, and if she doesn't agree with her, she will use spicy hands. I always thought that Xu Hui was just a Dan Dao genius, but I didn't expect that he was still a martial arts genius. Senior Brother Xu Hui was so handsome just now, but unfortunately he was a little nervous just now, and he didn't see it very really. Nangong Li was still immersed in the battle just now.

Although Nangong Li is also a spirit-level master, the use of spiritual power and martial arts skills are a mess, and she even forgot to dodge, let alone use her hand to defend against the enemy.

Zhu Can originally thought that coming here was just a farce, but after fighting with Ding Yi, she changed her opinion.

"Senior sister, you better leave first, Senior Sister Zhu Can is a guest I invited, I don't want you to have endless disputes. On the other side, Ding Yi was doing Nangong Li's ideological work.

Nangong Li was very worried about Ding Yi's safety, but she knew that unless this Rong Dingfeng came forward in person by her irresponsible master, even if the five true disciples of the Rong Dingfeng, plus nearly a hundred outer disciples, would not be Zhu Can's opponents.

I don't understand why Xu Hui wanted to attract Zhu Can, thinking of the story he told last night, it seems that Xu Hui has not forgotten his hatred.

Nangong Li was very reluctant, but she was a person who knew what to advance and retreat, so she didn't continue to insist.

"Zhu Can, if you dare to be unfavorable to my senior brother, I will do everything I can, and I will bite you a piece of meat, do you believe it or not?" Nangong Li said sharply.

Zhu Can snorted contemptuously and ignored her. Nangong Li didn't say much more, opened her fiery red wings, flew into the sky, and swept across the sky in a blink of an eye.

"Follow me. Ding Yi was also very straightforward, and took Zhu Can directly to the Dan room.

Zhu Can felt that this Xu Hui was mysterious and unpredictable, and when ordinary outer and inner disciples saw her, they were like avoiding snakes and scorpions, and it could be seen that this Xu Hui was really not afraid of her.

Walking to the door of the Danfang, Ding Yi turned back to Wang Yonggang and said: "The kitchen is still stewed with snow chicken, the pickles that I asked you to pickle a few days ago should be able to get out of the altar, after the outside is cleaned up, you go to eat, don't forget, there are guests here." ”

Wang Yonggang hurriedly nodded yes.

Zhu Can has never seen such a cultivator, and he is too good for his miscellaneous disciples. This is simply a bit unreasonable, is it worth it for these ant-like existences?

On a desk in the Dan room, Zhu Can's broken sword rested on it.

The refining of the cultivation weapon, to be honest, Ding Yi has not tried it yet. However, theoretical knowledge, procedures, and techniques ...... Ding Yi is actually very familiar with these.

Ding Yi's alchemy foundation is quite solid, but it was used to refine precision mechanism components and refine true weapons, and this is the first time.

Ding Yi picked up a severed sword head, carefully put it in front of his eyes and looked at it carefully, he used his spiritual power to convert it into an eye spirit talent, and by tapping the sword body, the listening device used the ear spirit talent to prove it again, and after a while, Ding Yi put down the broken sword.

"Two methods, the first one, the whole sword melts and is reforged. The second, using the inlay method, reassembles the broken sword. You pick one. Ding Yi looked up and said to Zhu Can.

"You're not a refining master, are you sure to repair my love sword?" Zhu Can was still a little suspicious.

Ding Yi pointed to the chopsticks beside Zhu Can and said, "You don't trust me, so you didn't eat a bite, since you don't believe me, why do you want to come here?"

Zhu Can hesitated for a moment and said, "You are not a true disciple, not even an inner disciple, why should I trust you?"

Ding Yi sneered: "I heard that you have found someone else to repair it, aren't those inner disciples and true disciples in your mouth not having this ability?"

Zhu Can said: "I don't know how to refine the weapon, as long as you can help me restore it to its original state, it's fine, as for how to operate, you can do it yourself." ”
