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

The ring suddenly turned into a ball of black smoke, and then the black smoke formed a circle of light blue barrier around Hisoka.

“Open it for me!” Hisoka shouted and spat out the ring in his mouth. There were deep marks on the surface of the ring, as if it had been cut by a sharp blade.

"As expected!" Hisoka smiled. Although this barrier was composed of formations, it was still too fragile, just like glass.

This ring is Hisoka's natal treasure. This ring is made from a fragment of an ancient ruins, which in turn is made from a black stone. There are many talismans engraved on the black stone, and the main material of the black stone is black ore. Because the ore is black, this black stone is called black iron. However, Hisoka's body does not belong to black iron. Hisoka's body is a very strong metal, which gives Hisoka some strange properties.

The fragments of black stone just happen to be able to restrain some strange formations, so this ring has a little value.

"Break the formation!" Xi Suo shouted again and threw the ring in his hand into the air. The ring turned into a meteor and hit the barrier. The runes on the barrier burst instantly, and a layer of black ripples spread in all directions.

Black ripples spread rapidly, and soon the barrier disappeared, revealing the scene inside.

Inside the barrier, there is a long corridor.

“Hahaha…” Hisoka was ecstatic and laughed loudly: “I know how to break the formation, hahaha…”

"But before I break it, I have to clean up these things first!"

Xiso's feet suddenly pushed off the ground, and he rushed towards the nearest formation. Xiso pressed his right palm on the formation, and then Xiso's body was bounced away by the formation.

“Hahaha, I see.” Hisoka smiled, “I see, it turns out that this barrier is an illusion.”

"This barrier is a kind of maze."

"The maze also has weaknesses. It will be easy as long as I find the weakness."

"Break the formation." Xisuo stretched out both hands and grabbed three talismans in a row, and then the three talismans fell on the formation.

"Boom..." A series of loud noises were heard, and the entire maze disappeared in an instant.

Hisoka rushed into the maze again, and then looked for the center of the maze.

"Found it!" A smile appeared on Hisoka's face: "Broken!" Hisoka shouted.

Hisoka threw a punch, hitting the center of the formation, and then the light at the center of the formation instantly dimmed.

Then, the light disappeared and the maze was broken.

Seeing that the formation had been broken, Hisoka turned to look at the boy, wanting to show off.

"Be careful!" The boy suddenly pushed Hisoka away, and then a silver light flew towards them like lightning.

Chapter 613 Appeared! The Soul Orb That Can Devour Souls

"Swoosh..." The silver light came straight towards the young man. The young man was startled and quickly dodged.

"Puff!" A silver light flashed across the boy's shoulder, leaving a wound. The bright red blood instantly dyed his clothes red.

"What a powerful attack!" The young man thought to himself, "If I had been a step late, or if you hadn't dodged in time, you would have been split in half by now."

"Yes, how do you feel now?" Hisoka helped the boy sit down and said anxiously.

"I'm fine!" The boy shook his head and said, "What should we do now? Should we continue moving forward?"

"We must keep moving forward, but if you can't bear it, just wait for me here," said Hisoka.

"I'm really fine, let's go." The young man nodded, and then the two of them walked towards the depths of the secret room.

Deep in the secret room, Hisoka's vision became wider. At the end of the secret room was a pitch-black door with the word "Fire Thunder" written on it. In the center of the secret room, a huge array plate was placed in the middle.

"The center of the formation is right on the formation plate." Xi Suo pointed to the formation plate in the middle and said to the young man.

"The center of the formation?" The young man looked puzzled.

Xi Suo nodded and said, "This formation is called 'Fire Thunder'. It uses a formation plate to control the operation of the formation. As long as the formation plate is destroyed, the formation eye will be automatically broken."

"Is it over after the formation is destroyed?" the young man said hurriedly.

"I don't know, why not give it a try?" Xi Suo sneered, then stretched out his right arm and punched the formation plate.

"Bang!" The formation plate shattered, and fragments flew everywhere. Xiso stretched out his left hand and grabbed it, and a gray bead fell into Xiso's hand.

This is a round bead. The surface of the bead is covered with complicated lines. These lines are intertwined to form a mysterious pattern. These patterns are combined to form a strange symbol. There is a word in the symbol: broken!

As soon as the word "broken" appeared, the entire formation plate trembled violently, and then the entire formation completely collapsed, and the gray bead turned into powder.

"Boom!" The dust dissipated, revealing a hole.

Outside the cave entrance is countless black magma, which is dark brown and emitting thick smoke. There is also a pillar supporting the cave entrance. On the pillar is a black lion carved with a pair of horns on its head.

"Hahaha, the formation is finally broken, the formation is finally broken." Hisoka jumped excitedly, then stepped into the cave.

"Boom boom..." The magma at the entrance of the cave rushed into Hisoka's feet madly. Hisoka seemed to be walking on clouds, floating towards the edge of hell.

"Boom!" With a loud noise, Xi Suo fell from the air. His chest was dented by the explosion, and a large amount of black blood flowed out. Xi Suo's eyes were wide open, and he stared at the bead on the ground, "What is this thing!"

"This is……"

"This bead is a soul bead!" the young man exclaimed. "Legend has it that the soul bead has the power to devour a person's soul. Once it devours a person, they will never be free again."

"Devouring people's souls!" Xi Suo took a breath of cold air: "Too cruel."

"Is this bead a soul bead?" After the young man finished speaking, he suddenly thought of something.

Chapter 614: Skeletons Coming Out of the Darkness

"Hurry up!" the boy urged, "Otherwise, I can't escape."

"Okay!" Xi Suo gritted his teeth and said, "Let's go!"

"Swish!" Hisoka turned into a shadow and rushed towards the cave entrance.

"Bang bang!" As the two men entered the cave, two explosions were heard behind them.

Xi Suo turned his head and saw two dark holes on the stone wall at the entrance of the cave.

Hisoka swallowed, then turned around and started running. The boy followed behind Hisoka, and the two of them ran forward together. They ran for a long time before they stopped.

After stopping, both of them breathed a sigh of relief.

"It was so scary! I almost lost my life." Hisoka patted his chest, still feeling scared.

“Me too.” The boy wiped the sweat from his forehead and smiled bitterly: “I thought I was going to die in there.”

"Your strength is relatively weak. I don't know if we can get out of here?" Hisoka asked worriedly.

"It should be possible. Let's look for it first." The boy said, and turned around to look for it.

The two searched for a while and finally found that there was no exit at all, because there was only one road, and at the end of this road was endless black flames.

"This is not a solution. This is the only way out. Are we going to die here together?" Hisoka was a little depressed.

"I think this formation is not simple. Maybe there are other ways to get out." The young man frowned and said, "How about this! You stay here and I will go out by myself."

Xi Suo shook his head and said, "No! If you stay and lead the way, we won't be able to get out. There must be another exit here. We have to find it."

"Okay! In that case, let's search separately!" the young man said after thinking for a while.

"Okay." Hisoka agreed.

The boy turned around and walked away, while Hisoka walked slowly in another direction.

"How many exits are there here?" the boy murmured. He didn't dare to walk around randomly.

Hisoka returned along the same route and after walking for a while, he found that the boy had not caught up with him.

"Could this guy be lost?" Hisoka wondered doubtfully.

Just at this moment, a fork appeared in front of him, and Hisoka got excited and chose one of them.

"Bang bang..." Hisoka was walking on a path and suddenly bumped into a wall. The wall was about one and a half meters high and three centimeters thick.

"Damn!" Hisoka cursed and continued walking forward.

As they walked, suddenly, a dark passage appeared in front of them. The passage was very long, and when Hisoka stood inside, he felt the chilling cold.

"What the hell is this place?" Hisoka muttered, and continued walking.

At this time, a lot of white bones suddenly appeared around the passage, and on each bone, there was a human head hanging.

"What's going on!" When Hisoka saw the heads of these people, he couldn't help but let out a scream of fear, then quickly stepped back.

"Crack!" At this time, a human skull came out from the darkness. Then, the skull slowly stretched out a pair of skinny hands. Then, another skeleton slowly walked out of the darkness, holding weapons, with blue flames burning in their eye sockets, and approached Hisoka step by step.

Chapter 615: Fighting Side by Side Again

Hisoka's pupils contracted and he quickly retreated backwards.

Hisoka's speed was very fast, but he was still a little slow, and the skull had surrounded Hisoka.

"Swoosh..." Two sounds of breaking through the air came from behind. Xi Suo turned around and saw two sword beams shooting towards him.

Xiso quickly raised his arms to block, and the two sword beams hit Xiso's arms. Xiso felt a huge force coming, and Xiso couldn't help but sit down on the ground.

"Boom!" At this time, Hisoka heard a loud noise. He turned his head and saw that he was surrounded by skulls. Hisoka quickly got up.

"Bang bang!" Hisoka kept attacking and dodging, and all his attacks fell on the skeleton's body.

The skeleton's defense was very strong, and Hisoka's attack did not cause any damage to it. Instead, his hand was paralyzed by the shock.

"Damn it! The defense of these skulls is really strong." Hisoka cursed inwardly.

"Boom!" There was another muffled sound, and Hisoka's arm was attacked several times again. Hisoka hurriedly retreated, but the skeleton was unwilling to give up the attack.

A feeling of despair arose in Hisoka's heart. He didn't know how long he could hold on. If he continued like this, he would surely be exhausted to death.

"Damn it!" Hisoka roared, rushed towards a skeleton, and then attacked it with his fists.

"Puff..." A puff of white smoke rose up, and the skeleton's shoulder was hit by Hisoka.

"Boom!" Another dull sound was heard, and a big hole appeared on the top of the skeleton's head, but Hisoka was not intact either.

The young man not far away was also stunned when he saw this, and hurriedly ran towards Hisoka.

"What are you doing?" asked Hisoka.

When the boy saw Hisoka's condition, a trace of worry appeared on his face.

"Let me help you! This way you can feel more relaxed." said the boy.

"No need." Hisoka refused.

When the boy saw that Hisoka rejected him, he felt sad and said, "Hisoka, if you die, I won't be able to live."

Hearing this, Hisoka was stunned, turned around quickly, and looked at the boy.

A smile appeared on the boy's lips, and then he dived into the pile of skulls.

"Boom!" There was another muffled sound behind Hisoka. The head of a skeleton was smashed by the young man, and the young man's head popped out of the skull.

"Don't worry, I'm here!"

The boy continued to walk towards Hisoka. At this time, Hisoka felt a strong threat. This threat appeared in Hisoka's mind. At this moment, Hisoka finally understood why he encountered these skulls, because there was a strong sense of crisis in this place. This danger came from Hisoka's own danger intuition.

"What are you going to do?" Hisoka asked, looking at the boy.

"I will help you defeat them." said the boy.

"Haha!" Hisoka laughed faintly: "Aren't you a little too naive? This is the power of the soul, which is simply not something that ordinary humans can resist."

"Then let's give it a try!" The boy looked confident, and continued to rush forward. When the skeletons saw the boy rushing towards them, they immediately raised their weapons, aimed at the boy, and attacked him together.

Chapter 616: The Young Man Uses His Protective Qi

These skeletons are very powerful, each of them is at the sixth level. Xi Suo did not dare to be careless. He quickly dodged and avoided the skeletons' attacks.

"Whoosh..." The skeleton's attack hit the stone wall, and dents suddenly appeared on the stone wall. However, these dents only flashed for a moment.

"I'll help you, you take a rest." The young man said as he rushed over, holding a short knife in his hand and chopped down fiercely.

"Boom!" With a dull sound, Xi Suo's body was chopped away. Xi Suo fell to the ground, and quickly rolled up and stood up, looking at the young man with a serious face.

"Hiso, don't worry about me, just run!" The boy shouted when he saw Hisoka standing up.

"Run! Run?" Xi Suo sneered: "Do you think I'm a fool? These things can only leave here by killing me. I won't abandon my friends and run away."

"But you are no match for these monsters!" the boy shouted anxiously.

Hisoka ignored the young man and looked at the group of skeletons again. At this time, the group of skeletons raised their weapons again and pounced towards Hisoka.
