The video takes stock of the heavens, starting with the Fire Dragon King Natsu!

Yao Lao was silent for a moment and then asked, "How can you be sure that Hisoka is the best?"

"I believe in my judgment, and I also know that you will definitely agree to my request." The old man said.

After hearing the old man's words, Yao Lao fell into deep thought.

The old man stood there, motionless, quietly waiting for Yao Lao's answer.

"Okay! I promise you!" Yao Lao said after hesitating for a long time.

"Thank you for your support, Yao Lao!" the old man said, "I hope Hisoka's performance satisfies you."

After saying that, the old man slowly left.

……

"This is my job." Yao Lao looked at Xi Suo and said, "Your task is very simple. Classify these herbs. Each herb needs your cooperation. Moreover, each classification requires your soul imprint. You must use the soul imprint to control the medicinal properties of each herb."

"I understand." Xi Suo nodded. Without further ado, he immediately started to do what Yao Lao had instructed.

An hour later, Hisoka stopped classifying because all the herbs had been classified and each one had the characteristics of many herbs.

"Start refining the medicine now! I'll be watching from the side. If you have any questions, you can call me at any time. This time is your chance, you must seize it. If you don't, you won't achieve today's results!" Yao Lao said lightly.

"Yeah." Xi Suo nodded, and then began to prepare the medicine.

Alchemy is a very complicated job. If it were someone else, it would probably take a long time to do it well.

But for Hisoka, it was not difficult.

Xi Suo first adjusted his condition and then started to refine the medicine.

Xisuo refined a total of six pills, all of which were flame pills, which was Yao Lao's main task. If the refining was successful, it would be Yao Lao's honor. If the refining failed, he would also be punished.

Xiso started to refine the medicine, and Yao Lao kept staring at Xiso and watched from the side. If there was any problem, he would remind Xiso.

At this time, Yao Lao felt his heart beating violently, as if it was about to burst out of his chest.

Chapter 577: Hisoka Absorbs the Spiritual Power of the Phoenix Bracelet

He knew that he had begun to worry, because the recipe for the elixir was very precious this time, and Yao Lao didn't want Xi Suo to have any problems.

Just when Yao Lao was worried about Xiso's safety, Xiso suddenly opened his eyes.

"Successful?" Yao Lao couldn't help but blurt out.

Hisoka smiled and shook his head.

"You haven't succeeded yet? Your alchemy skills are very powerful, how could you not succeed?" Yao Lao asked anxiously. These pills were all carefully selected by him before being given to Xi Suo!

Xi Suo said, "I succeeded, but, Yao Lao, I am not an alchemist, so I did not refine six pills in one furnace, but sixty-three pills. This is because I used the power of fire. My fire power can increase the speed and success rate of alchemy. However, I also have a little problem, that is, the fire power is too strong. I can't fully master this fire power yet. I am still far away."

"The improvement of the power of fire cannot be fully mastered in a short period of time. It requires gradual practice." Yao Lao said, "Your success is also reasonable."

"But I still need Master Yao to teach me the art of alchemy. If I can master more fire power, I can quickly increase the probability of refining pills." Xiso said.

"I can teach you some basic alchemy techniques. You can use these basic alchemy techniques to improve your alchemy skills. Of course, if you encounter a bottleneck, or have a bottleneck, you still need my help." Yao Lao said.

"Thank you, Yao Lao." Xi Suo said quickly.

Yao Lao smiled and said, "I won't bother you any more, just continue refining the medicine!"

After saying that, Yao Lao turned and left. After walking a few steps, he turned around and said, "Xi Suo, I can see that you are an excellent talent, but you still need to work hard. Only when you reach the level of a heavenly alchemist can you truly become a strong man. I am optimistic about you!"

Hearing Yao Lao's praise, Xi Suo smiled and said, "Don't worry! Yao Lao, I will definitely work hard to practice and strive to be promoted to a heavenly-level alchemist as soon as possible."

"Okay, I look forward to that day. However, you also have to pay attention. The task this time is more arduous. I want to see the results of your medicine refining." After saying that, Yao Lao disappeared into the house.

After Yao Lao disappeared, Xi Suo was the only one left in the house. Xi Suo sat beside the table and took out a piece of jade.

The jade artifact is a bracelet, which is a bit like ancient jade artifacts, except that there is a lifelike phoenix carved on it.

"Phoenix! Is this the alchemist that Yao Lao mentioned? This Yao Lao is quite good at playing. This bracelet is not only made of jade, but also made of the best jade!" Xiso murmured to himself.

Yao Lao was right. This was indeed a top-quality jade artifact. However, this jade artifact was not valuable.

Because after all, it is not a gem, it is just a jade, just a jade of better quality.

"It will be useless even if the medicine is successfully refined." Xiso said helplessly. Although he did not know how to distinguish the authenticity, this bracelet was definitely not authentic. It was just that the jade was of special quality, so Yao Lao called it a gem.

"Never mind. Since you're an alchemist, I have to see it. Why not give it a try?" After thinking about it, Xi Suo closed his eyes, circulated the internal Qi in his body, and merged the jade into his body.

As the jade merged into his body, Hisoka immediately felt a warm current rushing to his limbs and bones. Hisoka felt that his body had become lighter, and every pore in his body was cheering. Hisoka felt that his bones and skin seemed to be absorbing this heat. This comfortable feeling was very wonderful. Hisoka couldn't help but think how nice it would be if he could change his body into a snake so that he could absorb this heat.

"It's so comfortable!" After a while, Hisoka opened his eyes and said with emotion.

Although he did not absorb too much, he was able to control his body, convert the heat flow into his own power, and control his own power, which can be said to kill two birds with one stone.

"Master Yao, my medicine refining skills have improved a lot. I will definitely be able to refine good pills this time." Xiso said with a smile.

……

In Yaowang Valley, in Yao Lao’s house.

Yao Lao stood by the window looking at a big tree in the courtyard. His eyes were a little confused and a little dull.

Yao Lao was thinking about what he had just said to Xi Suo. Although Xi Suo did not hear clearly what he said just now, from his expression and reaction, Yao Lao knew that what he said was not wrong.

He is indeed a talented alchemist, but he still needs to work harder.

There is no doubt that Hisoka is making rapid progress. He can now control the power of fire in his body. Moreover, Hisoka also clearly feels that his alchemy skills have improved a lot.

This is what makes Hisoka happiest, as it proves that he is a genius alchemist.

Chapter 578: Refining the Eighth-Grade Elixir Phoenix Pill

"Master Yao, what's wrong with you?" At this time, the disciple's voice came from outside the door.

Yao Lao turned around and saw his disciple coming over with food.

"How is his condition?" asked Yao Lao.

"Xiso is in good condition. I estimate that after a while, Xiso will be able to refine potions above the seventh level." said the disciple.

Yao Lao nodded with satisfaction and said, "This kid is worthy of being my apprentice. This kind of perseverance is really rare. This time, I want to see him refine an eighth-grade elixir with my own eyes."

"Master Yao, do you think Xisuo can refine an eighth-grade elixir?" the disciple couldn't help but ask.

"What do you think?" Yao Lao asked back.

"Hard to say."

"Then wait! We'll see."

The pill that Xiso refined this time was called Phoenix Pill, a seventh-grade potion. This kind of pill had extremely high requirements for soul power, and most people could not refine it, so Yao Lao gave Xiso a seventh-grade potion and asked him to refine this potion.

Of course, Yao Lao absolutely trusted Xiso, because he had witnessed Xiso refining a seventh-grade elixir with his own eyes.

"Xi Suo, you must not let your master down!" Yao Lao whispered, then he turned around and looked into the distance.

……

In the Alchemist Guild, Hisoka's room.

Hisoka was sitting cross-legged on the bed, with white mist coming out of his body and a medicinal fragrance wafting from the mist. Hisoka was no longer wearing any clothes, completely naked, with all his muscles exposed to the air.

"This time, I must prepare all the medicinal materials, and then start refining the Phoenix Pill." Xi Suo thought secretly in his heart.

Phoenix Pill is a very powerful healing pill, and it is also the potion that Hisoka needs most at the moment.

Generally speaking, the pills made by alchemists are for curing diseases and saving lives, or they are some auxiliary things, such as pills for increasing true qi, strengthening soul power, etc.

The Phoenix Pill is different. It is a kind of pill that can increase the power of the soul. The effect of this kind of pill is more significant than increasing true qi.

Not long after, the fog gradually dissipated, revealing Hisoka's appearance.

At this moment, the sweat on his body had dried, and his face was rosy and he looked energetic.

There were some medicinal herbs on the table next to Xi Suo. He picked up one and began to prepare it.

The medicinal herb turned into ashes in his palm. This medicinal herb was one of the main ingredients of the Phoenix Pill and also one of the most basic ingredients. However, this medicinal herb was also a very precious one. If it were an ordinary person, it would be difficult to turn it into powder even if they had refined a sixth-grade pill.

A quarter of an hour later, Xi Suo crushed the last piece of medicinal herb and threw it into the stove.

Hisoka's movements were skillful and gentle, as if he was dancing.

"Huh~" The medicine cauldron began to shake violently. Hisoka's face instantly turned red, and the blue veins on his forehead bulged out.

The pain of refining this kind of medicine is self-evident, because the Phoenix Pill is a very advanced medicine and its materials are very rare, so it is not easy to refine. Moreover, the temperature of the medicine cauldron is too high. If it were an ordinary person, it would probably have been burnt long ago.

"Pfft~"

Finally, Hisoka couldn't help but spit out a mouthful of blood. His hands were also burned. He used his spiritual power to suppress his blood and prevent it from seeping out.

"Xi Suo, don't be nervous. Everything is ready. Take your time." Yao Lao's voice sounded, and then his soul power enveloped Xi Suo's body. Warm soul power wrapped around Xi Suo and relieved his pain.

Time passed bit by bit, and soon, half a month had gone by. During this half month, Yao Lao had been observing Xiso, and was relieved to see that Xiso was fine. However, the Phoenix Pill refined by Xiso was still a seventh-grade pill. This was his first attempt, so Yao Lao was a little uneasy. However, Xiso refined the pill very smoothly and successfully, which made Yao Lao feel relieved.

A smile appeared on Yao Lao's lips, and then he restrained his soul power.

At this moment, Hisoka's skin turned pale, as if it was made of paper, and a trace of fatigue appeared on his face.

"It's finally done." Hisoka breathed a sigh of relief, a look of joy on his face.

"You have made great progress in the past half month. Although you are only a five-star junior alchemist, your movements when refining pills are very skillful and flawless. I believe that in the near future, your realm will definitely be improved. However, now is not the right time. After you are promoted to a five-star peak alchemist, you can try to make it to the seventh level." said Yao Lao.

"Huh~" Hisoka let out a breath.

"Xi Suo, you should rest for a while before practicing!" Yao Lao said, and then his voice disappeared.

Chapter 579: Transformation Brought by the Silver Needle

After hearing Yao Lao's voice disappear, Hisoka's figure also disappeared.

Then, he returned to his room, sat cross-legged on the bed, closed his eyes, and fell into a deep sleep. He had never stopped practicing these days, and he had not eaten or drunk water in these days, so he had to replenish his strength.

……

That night, Hisoka had just laid down on the bed when wisps of faint black air surged out from the top of his head, gathering towards his mind bit by bit, and then entered his brain.

"Ah~"

Hisoka suddenly screamed.

Then, he suddenly opened his eyes, two balls of purple flames flashed in his eyes, and three silver needles appeared in his hands.

"What is this?" Xi Suo murmured, and then he inserted the silver needle into his forehead.

"Pfft~"

After three silver needles were inserted into his forehead, Xi Suo immediately felt waves of pain in his head. His whole body trembled violently, but beads of sweat the size of beans appeared on his forehead.

"Ah~"

Hisoka let out a long howl towards the sky, a ferocious look on his face. He kept twitching, and the muscles on his face were twisted. He looked a little scary, like the face of a devil.

An extremely violent aura emanated from him, and even the wooden walls of his room were torn apart by his aura. His clothes were tattered, revealing his bronze skin, which looked extremely attractive.

It was unknown how long it lasted before Hisoka's momentum gradually weakened and his eyes regained clarity.

"Hi~"

A piercing pain spread throughout his body, and Hisoka couldn't help but gasp.

Hisoka looked down at his left hand. In his left hand, he was holding a handful of silver needles. There were densely packed tiny needle holes on his left hand.

After seeing the bone-deep scar on his right wrist, Hisoka couldn't help but frown.

"What on earth is going on?" Hisoka murmured.

Hisoka felt the aura in his body. His strength had indeed improved during this period of time. However, his strength was still far from the level he hoped for. After all, his alchemy skills were only average. He still had to rely on his own continuous exploration to improve his alchemy skills.

"These days, I have been suffering from painful torture every day, which makes me more sober. I must work hard. Once my alchemy skills reach the level of an initial peak alchemist, I will be able to master stronger alchemy skills. I won't have to worry even if I encounter higher-level medicinal materials. Even if I encounter six-star medicinal materials, I am confident that I can refine pills." Xiso murmured.

"I must improve my strength as soon as possible, otherwise, if someone else refines these things in the future, I may not dare to refine them."

Xi Suo muttered to himself, then continued to lie down, ready to practice for a while.

His body is in the stage of transformation, and each transformation will bring about a huge change, just like his meridians. After the transformation, some changes will also occur, making his body more adaptable to refining medicinal materials. Moreover, his meridians are no longer ordinary meridians. They are much thicker than those of other people. His meridians are much wider than those of ordinary people. If the meridians of ordinary people are just a stream, then his meridians are a vast ocean, much wider than those of ordinary people. At the same time, his meridians also contain countless impurities, and the impurities are very rich. Every time he absorbs the medicinal power, he must eliminate the impurities in his body.

He did not dare to delay and started practicing immediately.

In his meridians, spirit cores were constantly jumping, and traces of medicinal power flowed through the spirit cores and into his body.
