Xu Feng took a step and walked towards the space crack.

"Fairy envoy, what are you going to do?" Princess Su Yue, who was not far away, said in horror.

"I'll go in and take a look. Maybe I can find a way to close the space crack from the inner demon world!" Xu Feng said in a deep voice.

"What?" Princess Su Yue was shocked: "That's the Heart Demon Realm, what if, what if..."

Princess Su Yue didn't dare to continue speaking. The Heart Demon Realm was a complete world just like the Jiuji Xuantian World, but the Heart Demon Realm was full of demons. The most numerous were the heart demons, but besides the heart demons, there were many other demons.

"Fairy Envoy, the Heart Demon Realm is only a part of the Earth Demon Realm. Once you enter, if the space rift closes, there will be no way to come back!" Princess Su Yue explained hurriedly.

"Earth Demon Realm?" Xu Feng was stunned. He had heard of this name in his previous life. Many secret realm apostles liked to explore the Earth Demon Realm. It was said to be very dangerous, but there were also many treasures! "Yes, there are two kinds of demons. One kind lives above the nine heavens and is called the Heavenly Demon Realm. The other kind lives below the nine abysses and is called the Earth Demon Realm. The Heart Demon is just one kind of Earth Demon!" Princess Su Yue explained.

"Haha, what should I do? I can't stay here forever!" Xu Feng shrugged and said.

The most important thing is that he has not yet overcome his inner demon tribulation. Somehow, Xu Feng sensed that there was a glimmer of opportunity in the gap in the space in front of him. If he did not go in, his inner demon tribulation would probably be stuck here, unable to move forward. Then, the immortal cultivation method of "Wanjie Moshen Gong" would be useless.

"This is the disadvantage of overcoming the tribulation. Not to mention the danger, if you don't notice the last opportunity, you will most likely be stuck in a certain tribulation!" Xu Feng said to himself.

The founder of Kaimai only cultivated to the twelfth tribulation power. Xu Feng suspected that the founder might not have found the opportunity when he was overcoming the twelfth tribulation, and as a result, he was stuck at the twelfth tribulation power.

"The uncertainty of overcoming the tribulation is too great. After overcoming the inner demon tribulation, I should try to find more other skills to improve my tribulation power in the future." Xu Feng said to himself.

“Why don’t you let the immortal guard here first? I will go to the Great Yan Imperial City to report the situation and find a few formation masters to seal this space gap!” Princess Su Yue said in a deep voice: “I have a formation master in the Great Yan. In addition, the two dynasties of Da Lu and Da Zheng also have a formation master each. When the time comes, with the power of three formation masters, we should be able to seal this space gap!”

After listening to this, Xu Feng smiled bitterly and shook his head. This place was at least three thousand miles away from the Dayan Dynasty. In addition, to seal this place, formation masters from two other dynasties would be needed. The round trip, plus notifying the other two dynasties, would take at least three months.

Moreover, it is not certain whether the other two dynasties are willing to send the only formation master in the country. After all, this space crack appeared in the Dayan Dynasty, which is far away from the other two dynasties.

Moreover, it is not enough to have a formation master alone, a large amount of precious formation sealing materials are also needed...

Xu Feng estimated that if three formation masters could get here with the formation materials within half a year, it would be considered a quick move.

Rather than staying here for more than half a year, Xu Feng would rather take some risks and enter the space crack to find out what's going on. After all, the space crack can't be opened for no reason.

"Forget it, I'll go in and take a look. The Demonic Realm is not as dangerous as you think!" After Xu Feng finished speaking, he stepped into the gap in space and his figure disappeared.

In his previous life, Xu Feng had several friends who, like him, had exhausted their potential and were unable to advance to the secret realm. They could only explore and look for opportunities in various secret realms. They often went to the Demon Realm, and after going there several times, they didn't see any danger.

After going to the Demon Realm a few times, they never showed up again. Xu Feng always thought that they made a fortune in the Demon Realm and returned to their hometown to live an ordinary life.

"Hey, fairy messenger..." Princess Su Yue wanted to stop him, but Xu Feng's figure had already disappeared into the space crack. Princess Su Yue stood there for a long time, and finally couldn't help but let out a sigh.

"In that case, I will stay here for the immortal envoy for three days. I hope that the immortal envoy can return safely after three days!" Princess Su Yue said to herself.

…

When Xu Feng entered the space crack, he saw a flash before his eyes and the surrounding scene suddenly changed.

This is the Demonic Realm. Xu Feng is in a valley. Both the ground and the rock walls are ink-black. However, in the darkness, there are dark red lights that flicker continuously, just like breathing, revealing a strange smell.

The sky and the earth were dark, with countless black smoke floating in the sky. If you look closely, that should be the black cloud formed by a large group of inner demons gathering together. There was no trace of vegetation in the entire valley, it was bare and full of deathly silence.

"What opportunities will there be here?" Xu Feng frowned, not understanding why his friends from his previous life liked to come to the Demon World to explore and look for opportunities.

At this moment, Xu Feng was suddenly attracted by several figures. It turned out that Xu Feng was not the only one in the valley. Deep in the valley, five apostles of the secret realm were facing a deep cave, ready for battle.

"High-level apostles?" Xu Feng raised his eyebrows. The five people in front of him were all level seven apostles. They were all secret realm apostles who had reached the Hunyuan Ruyi realm.

However, the five people in front of him were obviously not Chinese. They looked a bit like the apostles of the secret realm in Europe. Each of them was tall and strong, and looking at the equipment on their bodies, one could guess their respective professions almost exactly.

"Paladin, Hunter, Wizard, Gunner, Healer, haha, a standard five-man team!" Xu Feng couldn't help laughing.

He was very familiar with this kind of professional configuration. As a mage in his previous life, he had joined such a team more than once and served as a firing point in the team.

This is a perfect treasure-hunting team with a very high tolerance rate. They can challenge BOSSes that are one level higher than them. Even if the challenge fails, there is a high chance that they can escape unscathed.

At this time, black smoke continued to float out of the deep cave they were facing. A low roar came from the cave, shaking the entire cave slightly and causing gravel to fall continuously.

"Be careful, the BOSS is coming out!" The wizard, who is a ranged profession and also plays the role of commander, noticed something unusual. The wizard, who was covered in a gray robe and hood, said in a deep voice, with light flashing on his fingertips. A fingernail-sized ball of light with long and short light spikes around it floated up from the wizard's fingertips.

Under the wizard's control, the ball of light floated towards the deep cave.

This is a detection skill of the wizard. Although it is only a zero-level magic, it is extremely effective and can share vision with the wizard.

After a moment, the wizard's face turned pale, obviously he was hit by the backlash of the spell! The ball of light that entered the cave was destroyed by the unknown creature.

"Be careful, it's coming out, get ready for battle!" the wizard shouted.

There is no wrong version in the 1619 book forum!

A moment later, a thick black smoke rushed out of the cave. The strong energy was full of corrosive smell. The face of the paladin closest to the cave entrance changed, and he shouted hurriedly: "The black smoke is poisonous, push back!"

The next moment, a head made entirely of black smoke popped out of the cave and let out a terrifying roar at the few people.

The black smoke that makes up the head will continue to float in the air, making this huge head look very hideous and weird.

"Ranged profession, attack!"

At a command, hunters, wizards, and gunners began to attack the huge smoke head that was sticking out of the cave entrance;

Whoosh, whoosh, whoosh~ Boom~ Unfortunately, this huge smoke head seems to be immune to physical attacks. Only the wizard's fireball can cause some damage to it. Whether it is the long arrows shot by the hunter or the bullets shot by the gunman, they all pass through the smoke head and shoot into the cave behind.

"Physical immunity!" The wizard's face suddenly turned ugly. This was one of the most difficult situations they had encountered. Physical immunity almost made their team immune to half of the damage. It was foreseeable that this would be a very difficult battle. If he had a choice, the wizard as the commander would even want to directly give the order to retreat.

Xu Feng slowly opened his eyes between his eyebrows and looked towards the huge smoke head. After a while, the attributes of the huge smoke head appeared in Xu Feng's eyes.

"The leader of the Heart-Eating Demon has the characteristic of corrosion. Haha, this team is in trouble!" After Xu Feng saw the attributes of the huge smoke head in front of him, he couldn't help but shook his head and laughed.

It is a leader-level BOSS, and also a heart-eating demon among the inner demons, with corrosive characteristics.

You know, characteristic corrosion doesn't just refer to corroding the body, but more importantly, corroding the mind! Possessing the characteristic of corrosion is equivalent to enhancing the innate skills of the inner demon.

The Heart-Eating Demon is a type of heart demon, but its methods are more cruel than ordinary heart demons. It not only likes to devour human minds, but also likes to devour human hearts. Humans who die at its hands often do not even leave a complete corpse.

Roar~ The Heart-Eating Demon leader spewed out a thick smoke towards everyone and began to slowly extend his entire body. After a while, two arms made entirely of black smoke squeezed out of the cave and grabbed the rock wall at the entrance of the cave, as if they were going to pull out their entire body.

"Attack, attack with all your strength!" the wizard ordered loudly, "Use energy attacks, don't just use physical attacks!"

All of a sudden, all kinds of skills that shone with light attacked the Heart-Eating Demon leader. Explosions sounded one after another, constantly blasting big holes in the Heart-Eating Demon's huge smoke body.

The giant Heart-Eating Demon leader finally crawled out of the cave. Its body was made entirely of black smoke and was about ten meters tall. Above the waist, one could still see some human shape, but below the waist, it was just a ball of swirling black smoke, looking like a giant monster.
