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

A smile appeared on Hisoka's face.

"Where is this?" Hisoka muttered to himself. His face had become much redder and his body had regained its strength. He slowly climbed up.

"Meow!" The fat cat also climbed up, its eyes wide open, looking at Hisoka with a curious expression.

"This...how did I get out of the room?" Hisoka looked around and couldn't help but exclaim in admiration.

"Meow~"

The fat cat let out a series of happy cries.

"I see." Hisoka nodded in sudden realization.

"This is your masterpiece!" said Hisoka, reaching out and touching the fat cat's head.

"Meow~" The fat cat let out a happy cry, then jumped into Hisoka's arms and rubbed against him.

"So cute." Hisoka smiled and stretched out his hand to pat the little thing in his arms.

Xi Suo felt weak and his face turned pale. He no longer wanted to refine the "Transformation Pill".

"Whoosh!"

Suddenly a strong wind blew, and a man in black stood in front of Hisoka.

"Who sent you?" Xi Suo asked with a frown.

"Humph! I don't want to waste my time with you." The man in black said coldly, "Hand over the pills you made!"

Xi Suo looked at the man in black and said calmly, "If I don't hand it over, what can you do to me?"

"You're looking for death." The man in black shouted angrily, "Kill you!"

"Shh!"

The man in black was extremely fast. He swung his sword and the sword light flashed.

"Boom!"

A loud and earth-shaking sound burst out from his sword, and Hisoka flew backwards and hit a tree heavily. The tree collapsed and he was knocked to the ground.

"puff!"

Hisoka spat out blood again.

"You are too young. You can't even block one of my moves!" the man in black laughed proudly.

"Really?" A strange smile appeared on Hisoka's face.

The man in black was stunned. Before he could understand what was going on, a fist suddenly appeared in front of him and hit him hard in the abdomen.

Chapter 628 I don't care about your life

"puff!"

The man in black spat out a mouthful of blood. His entire chest was sunken. His face turned frighteningly pale and he spat out blood from his mouth.

"You're not dead?" The man in black looked at Hisoka in surprise. His eyes bulged out and his face became ferocious. "You're not dead?"

Hisoka stood up slowly, a smile on his face. He was full of strength, like a wild beast.

"Although your strength is good, it is not enough to kill me. I am stronger now than before. I think you should be able to feel it!" Hisoka said with a smile.

"Impossible, absolutely impossible." Fear flashed in the eyes of the man in black. "Your strength is obviously only at the intermediate level. How could you become so strong? I won't accept this, I won't accept this!"

A look of madness appeared on the face of the man in black, his arms were shaking, he felt his body was collapsing, his body seemed to be torn apart, this pain was far beyond what he could bear, the man in black roared madly.

"Aren't you trying to steal my pill? I'll give it to you!" Xiso stretched out his right hand, and in the palm of his right hand was a pill emitting rich spiritual energy.

"How dare you play tricks on me? You actually lied to me?" The man in black widened his eyes and shouted angrily, "You despicable villain."

"You were the one who attacked me first, why should I fight back? A villain like you is not worthy of being my opponent, Xiso, let alone possessing the noble elixirs of our Medicine King Valley." Xiso said lightly.

There was a look of resentment in the eyes of the man in black.

"Go to hell!" The man in black suddenly rushed out, his body disappeared in an instant, and the next moment, he appeared behind Xi Suo and stabbed Xi Suo's neck with a sword.

"call out!"

Just as he was about to stab Hisoka's neck, his body paused, because he found that Hisoka appeared in front of him at some point and knocked him away with a palm.

"Oh!"

The man in black fell to the ground, spitting blood.

"You...what kind of monster are you? Why can't I hurt you?" The man in black looked at Hisoka in surprise.

Hisoka's body flashed and instantly came to the side of the man in black. He kicked him and the man in black was kicked away.

"Pfft!"

The man in black fell to the ground.

"How is this possible? How could your strength increase so much?" The man in black struggled to get up from the ground and asked Hisoka.

Hisoka glanced at the man in black, then walked up to him and grabbed his throat with his hands.

“You…” The black-clothed man’s pupils shrank suddenly. He stared at Hisoka with wide eyes, an expression of disbelief on his face. “No… Impossible…”

"Your attack may be fatal to others, but it has no effect on me." said Hisoka.

The man in black opened his mouth and wanted to speak, but in the end, nothing came out.

"Tell me, who asked you to come here?" Xi Suo said, "Also, how did you get in touch with each other?"

"You want to kill me?" The man in black looked at Hisoka and said coldly, "Even if I die, that mysterious man will not let you go."

Xi Suo smiled slightly, shook his head, and said, "I don't care about your life, I just want to know who asked you to come and get the elixir."

Chapter 629: The black-clad man was scared away, and Xi Suo went to Yao Lao's residence

After hearing what Hisoka said, the man in black was shocked. He was silent for a while, then lowered his head and said through gritted teeth: "Kill me! I will not betray my employer. I will keep my mouth shut forever, as if I had never appeared."

Hisoka let go of the man in black, turned around and took a few steps.

"What are you going to do?" The man in black looked at Hisoka, his eyes full of vigilance, "Are you really planning to kill me?"

Xi Suo shook his head and said, "It's easy to kill you, but I won't be willing to let you go so easily. I want to get something out of you."

"Humph!" The man in black snorted coldly, "Don't even think about getting anything out of me."

"Really?" Hisoka looked at him with a smile.

"My strength is not as good as yours. I admit defeat. I admit defeat. Okay?" The man in black looked at Xi Suo and said. He knew that the gap between his strength and Xi Suo's was too big. If he continued to fight, he would definitely not be Xi Suo's opponent. In this case, he might as well admit defeat. Anyway, he also got a ninth-grade marrow cleansing pill.

"No." The corners of Hisoka's mouth curled up slightly, and his eyes were full of amusement as he looked at the man in black.

"Then I won't tell anyone about this either." The man in black said, "I promise."

Xi Suo shook his head and said, "I want you to tell your employer something." Xi Suo added, "He won't get what he wants, whether it's my life or the things in Medicine King Valley, he won't get them!"

The man in black glanced at Hisoka and nodded.

"Well, goodbye!" Xi Suo nodded slightly, then walked straight out of the house and disappeared from Xi Suo's sight.

"call……"

The man in black looked at Hisoka's disappearing back, he took a long breath, and then slowly sat down on the ground.

The man in black wiped the sweat from his forehead. This time, he was really scared. He never thought that one day he would meet a master like Hisoka. The strength that Hisoka just displayed made him feel creepy. Hisoka's strength might have surpassed his own, or even higher. Otherwise, Hisoka would not be able to withstand his full-strength attack.

"No, I'll die if I go back and report, so I'd better run away." The man in black stood up from the ground. He looked at his left wrist. The wound on his right wrist was still bleeding. He quickly took out the hemostatic pill and swallowed it, then quickly left here.

After the man in black left, Hisoka walked towards his room.

Xi Suo pushed open the door and found his room in a mess. There were several large black spots on the wall, the medicine cauldron and the table were overturned, medicine bottles were scattered all over the floor, and the furnishings in the entire room were deformed. Xi Suo walked into the room and cleaned it up.

After restoring everything to its original state, Xi Suo walked out of his room and prepared to look for Yao Lao. He knew that his failure in refining the elixir was very serious and he had to report it to Yao Lao so that he would know what to do next.

Xi Suo came to Yao Lao's residence and knocked on Yao Lao's door.

"Who?" Yao Lao shouted from inside.

"Master, it's me, Hisoka." Hisoka said, "I want to discuss something with you. Please open the door for me."

Yao Lao opened the door and walked out.

Chapter 630: Xi Suo receives nagging from Yao Lao

Seeing Xi Suo, a puzzled look appeared on his face. He looked at Xi Suo and said, "You come to me at this time, is there something wrong with the alchemy?"

"Master, my alchemy furnace is broken, and then..."

"Is it just that the alchemy furnace is broken?" Yao Lao looked at Xi Suo and said, "The medicinal materials are gone too."

"Yes, that's right." Xi Suo said, "Something else has happened. I would like you to go to my room and take a look."

"Let's go!" said Yao Lao.

The two walked out of Yao Lao's room and went towards Xi Suo's room.

"Master, although I have roughly cleaned the room, those traces are still there."

"After I took the pill, my body lost control and I passed out. When I woke up, I was outside in the garden."

"There's a new cat in the garden, and a man in black wants me to give him the elixir I made."

Hisoka kept talking on and on until the two of them reached the door of the room.

"Is that all?" Yao Lao looked at Xi Suo and said.

"Well, that seems to be it." Xi Suo said.

"As if?" Yao Lao looked at Xi Suo in confusion.

"It's not as if, that's all." Hisoka replied.

"So many things are enough to make you talk to me till here." Yao Lao glared at Xi Suo and said.

"Master, why do you say that?" Xi Suo looked at Yao Lao in confusion. "I'm just worried about the man in black. What if he comes to cause trouble for you?"

"Don't worry." Yao Lao said with a smile, "I am from Yaowang Valley. Even if those men in black are very brave, they dare not go to Yaowang Valley to cause trouble. Don't worry."

Yao Lao patted Xi Suo's shoulder and walked into the room. He was stunned when he saw the scene in the room. Although the room had been cleaned, there were still traces on the wall. Yao Lao frowned.

"You kid, did you take other elixirs when you were refining the pill? This level of explosion shows that your timing is not right!" Yao Lao grabbed Xi Suo's ear and said angrily.

“It hurts, it hurts.” Hisoka said quickly.

"From now on, don't use these things indiscriminately." Yao Lao loosened his palm, then turned around and waved his fist at Xi Suo.

"Yes, yes, I will definitely not mess around next time." Hisoka nodded quickly in agreement.

"That's right." Yao Lao said, "Next time you make pills, remember not to take random pills."

"I know, I know, Master, please let go, it hurts." Xi Suo broke free from Kai Yao Lao's control.

Yao Lao looked at Xi Suo with a smile and said, "Now you feel the pain, kid."

"Master, please don't talk bad about me. I just want to give it a try." Xi Suo said.

"I've told you many times that the medicinal herbs this time are very expensive, and you still dare to mess around. It's lucky enough that I didn't punish you to buy new ones!" Yao Lao scolded angrily.

"I know, I know. There won't be a next time." Hisoka apologized quickly.

"Come back to my residence with me. This time I will watch you making the elixir." After saying this, Yao Lao turned and left.

Xi Suo followed behind Yao Lao, jogging all the way, and finally caught up with Yao Lao.

The two men came to the house where Yao Lao lived. Yao Lao stopped, turned to look at Xi Suo, and said, "Don't be lazy tonight, practice alchemy obediently!"

"Okay, Master." said Hisoka.

Yao Lao looked at Xi Suo's appearance, sighed, and said: "Hey, you are my only disciple, you really make me worry."

Chapter 631: Yao Lao supervises Xi Suo in refining the three-pattern pill

"Master, I was wrong this time." Xi Suo lowered his head and said, "I won't do it again in the future. Don't worry, I will work hard to practice."

"Okay, let's not talk about this for now and let's go into the house." Yao Lao sighed and turned to walk into the room.
