Starting from the next day, the environment became more and more gloomy and weird.

The Fallen Forest a few days ago was dark and full of danger, too. But at the very least, the vegetation was dense, and all kinds of animals and birds were flying in and out of the forest.

But in the deepest part of the Fallen Forest was a completely different scene.

The trees nearby were sparse. The earth was covered in a layer of moss-like, but even thicker, putrid, purple humus. In the middle of the sparse forest that looked like the shadows of devils, there was a layer of vague purple mist. Not only was the sun and the sky invisible, even the endless Armageddon Mountains that pierced into the sky behind him were gone.

The small adventure team seemed to be lost in a purple ocean and did not know where they were.

Princess Summer told Theresa that this was the most mysterious and dangerous place in the Emerald Continent, the border between the Glorious Mortal Realm and the Blood Demon Sector.

Different from the imagination of ordinary people, there was no clear boundary between the human world and the demon world.

It was not as vivid as the bards described, either. The magnificent gate was made of the corpses of billions of lost creatures, guarded by skeleton soldiers, surrounded by the rushing Nether River, and guarded by the brutal three-headed dogs of the devil world.

In fact, the space between the Glorious Mortal World and the Blood Demon Sector was exactly such a lost area that was too vast to measure. It was wreathed in weird purple mist and terrifying tornadoes all year round.

Whenever a tornado rose up, it would bring the lost travelers to the Blood Demon Sector.

Of course, it was also possible that the hideous, ferocious devils in the Blood Demon Sector would be brought to the human world.

According to Theresa’s multiple trips to the sea of stars, she estimated that the so-called ‘lost zone’ was an extremely unstable space wrinkle or a super-large teleportation array left by the ancient high-tech civilization.

The ‘glorious world’ and the ‘Bloody Demon Sector’ should be two worlds.

…Just like the relationship between the War Heroes Sector and the Empyrean Terminus Sector, or the Blood Demon Sector and the Heaven’s Origin Sector.

In this place, even Black Jack, who had been confident and calm all the time, had lost the mood to dote on his harem.

Like a real commander-in-chief of the army, he commanded the harem to march forward in a united formation. Everyone was to hold hands and never to be separated.

It was said that the overwhelming storms in the Lost Zone would teleport the travelers to different areas of the Blood Demon Sector randomly.

It was very likely that they would be dozens of kilometers away from each other after they teleported to the Blood Demon Sector. That would be very bad.

“Everybody must be careful. No matter how terrifying the tornado is, you must hold the hands of the people around you tightly. Even if you are completely lost, don’t be scared. Every one of us has a ‘magical crystal smoke signal’ in our pocket. When we arrive in the Demon World, just send out the signal and let everyone gather around me without caring about anything!”

Black Jack’s voice was as loud as a bell. It was resolute and full of confidence.

Even Theresa, who was secretly jealous of him, had to admit that the guy had the charisma of an ignorant girl. He was like the only rooster in a flock of hens.

No wonder Princess Summer and her other sisters in the harem were fascinated by him.

Of course, he was not any worse than him.

One day, hehe…

Theresa swore that she would show the guy what a real man was.

“I’m a hundred percent a real man. You’re far from that, stinky man!” Theresa secretly made a face at Black Jack’s back.

The deeper they went into the lost zone, the denser the purple mist became. In the end, their visibility was no higher than twenty meters. The weirdly-shaped trees nearby seemed to have been burnt into charcoal, but they did not collapse because of the freezing force.

Theresa drew close and observed carefully, only to discover that the shadows were not trees but enormous armor and bones.

“Ah!”

Theresa shouted subconsciously.

Princess Summer and her sisters in the harem exclaimed, too.

Even Hela, who was best known for her knowledge, was somewhat moved when she saw the thousands of bones and armor scattered around.

But Jack Thunder was as calm as before, as if he had seen similar scenes before.

However, the weird brilliance deep inside his eyes indicated that he was not calm at all.

It was not surprise but excitement and ambition beyond description.

“According to the legends, ten thousand years ago, billions of devils in the Blood Demon Sector surged out of the ground and savaged the human world. They were known as the ‘Primeval Demonic Tribulation’.

Jack Thunder said casually, “Seeing that the entire human world was about to be occupied by the surging demon tide, the kings, heroes, and supreme sorcerers of the human world gathered and fought a bloody battle against the army of the demon race in the Armageddon Mountain. In the end, they successfully drove the demon race back to the devil world and sealed the place with a large area of the lost area. It was the ‘Battle of the Demons’.

“The feature of the lost zone is that the travelers and the army passing by will be randomly disrupted and distributed.

“That is to say, with the blockage of the Lost Area, even if the demon race gathers thousands of soldiers and horses to march toward the human world, they will still be torn apart and randomly teleported to a place hundreds of kilometers around the Armageddon Mountain. Then, they will completely lose the combat ability of their army. They will be unable to fight and can only harass.

“For small adventure teams such as ours, it is not a big problem. But for an army of more than 100,000 soldiers, it is impossible to launch a large-scale strategic attack. Therefore, the world of brightness has been peaceful for a thousand years.

“Of course, in such a case, the army of the Glorious Mortal Realm will find it difficult to attack the Blood Demon Sector on a large scale. However, the Blood Demon Sector is a barren land cursed by the gods in the first place. As long as the devil race does not want to attack the human world, they can do whatever they want in the Blood Demon Sector.

“It’s a pity that the effectiveness of the Lost Zone will vanish one day. The reappearance of the ancient black magic is not a good omen. I’m told that Lord Cooper is ambitious enough to unite the world of devils and put on another show of the apocalypse. We must stop the crisis before he completely solves the mysteries of the ancient black magic.

“Teresa, what are you thinking? Are you scared?”

Black Jack suddenly turned his eyes to Theresa, who was deep in thought.

Compared to the harem which he had grown tired of, he naturally paid special attention to this soul-stirring beauty.

“No, no… I-I am a little scared.”

Theresa shook her head and then nodded.

Of course, she was lying.

She was staring at the enormous bones and armor not because she was scared, but because she was slightly surprised.

She discovered that the super-large armors that perished in the ‘battle of the apocalypse’ were similar to crystal suits and the Titan Warriors!
