Located in Yellowstone National Park, Wyoming, USA, is the world's first national park. It was built in 1872 and was listed as a World Natural Heritage Site in 1978. The park is mainly located in the northwest corner of Wyoming. It extends northwest to Idaho and Montana, covering an area of ​​7,988 square kilometers.

Under the ground of Yellowstone National Park, there is a most destructive supervolcano on the earth. However, the entire park has the most diverse ecological landforms. Yellowstone Park is divided into five areas: the Mammoth Hot Springs area in the northwest is mainly limestone steps, so it is also called the hot step area; the northeast is Roosevelt District, which still retains the old western landscape; the middle is the canyon area, where you can view the Yellowstone Grand Canyon and waterfalls; the southeast is the Yellowstone Lake area, which is mainly the lake scenery; the west and southwest are geyser areas, which are full of geysers, hot springs, steam pools, hot water pools, mud and fume holes.

These magical scenery has also attracted thousands of tourists from all over the world to visit, but I'm afraid no one can imagine that the huge volcano underground in this park is actually the largest hell passage in the world.

As it was approaching midnight, the park tourists returned to the hotel or their own RV early, because the whole park would become a paradise for predators at night. A pile of green light flashed by, and a group of gray wolves emerged from the woods, watching the two black shadows walking towards the top of the volcano, the keen sense of the beasts told them that these two guys were definitely not as easy to mess with as they looked. So, under the leadership of the wolf, the wolves ran down the mountain, perhaps they could find an outlier reindeer there to fill their stomachs.

Mark followed Pierre and walked towards the top of the mountain. The creek along the way emitted a strong smell of sulfur. He took a deep breath, "It really smells of hell."

"Why, do you miss there very much?" Pirell asked with a smile.

"To be honest, sir, I'm used to staying in hell, and I really don't think there is anything good about the world. What are the uses of these wild beasts for demons? I really don't know what Lucifer and the others are trying to come up."

"Haha, Mark, you have a point of view. At first, these fallen demons attacked humans, whether it was temptation or killing, to obstruct God's mission. After all, they were all murdered by God, so they attacked these so-called Lambs of God to play a role in revenge."

Piley paused, sneered and continued, "Present in the present, they probably have forgotten their original intentions. The long years have made them turn into a dream deep in their hearts. This incident aroused their dream. Just like you said, is there anything they really need in the world? It's just to prove themselves to the cold-blooded God. Maybe they still hold on to the conquering the world, when God sees their power, he will call them back to heaven again. I'm afraid that they will not have any good endings in the end."

"Don't you remind them?"

"Haha, there is no need. First of all, those stubborn idiots won't listen to me at all. Second, it's no harm for us if they all die."

Both of them had a much better than ordinary people. They had arrived at the top of the mountain in just a few words. There was a small lake as beautiful as sapphire in the middle of the mountain. Of course, the reason for this beauty is that it contains a lot of minerals. Therefore, not only does no living creatures survive in such a beautiful lake, but also exudes a pungent smell of sulfur.

Pilie took out two magic weapons in his arms and handed them to Mark, asking him to put them in the designated position. Then he himself took the two magic weapons to a specific location. It was a small mini crater with white smoke. Pilie threw the magic weapons in without hesitation, and then the crater began to emit purple-red light. After all the four magic weapons were cast in, the entire top of the mountain began to emit purple-red light.

Pi Lie raised his hand and looked at the watch. The pointer was about to point to 12 o'clock in the middle of the night. He flashed and appeared at the position corresponding to the four magic weapons. When the pointer finally reached the position, he began to recite obscure mantras in his mouth, and the sign of a reverse pentagram appeared in his eyes.

Under Mark's gaze, the image of the thin old man of Pirene changed again. A thin man with an evil aura was standing there. Although his head was covered with white hair, his appearance was not very large. However, the most striking thing was that behind him was a pair of huge wings two meters long, and the color was black and white.

With Pilei casting spells on the Yellowstone Volcano, a huge purple-red vortex formed in a hole on the ground in hell on the territory of the five lords except Pilei and the demon king Leviathan. It seems that the place where the five demon kings' territories were established was the largest connection points for hell passages.

As Pilie's spells became faster and faster, the vortex was spinning faster and faster, and countless purple-red lightning flashed in it. The five demon kings led their elite troops to look at the once-in-a-lifetime grand occasion and couldn't help but grin. Seeing that their goal was finally about to reach, their joy was indescribable.

Roland was also mixed in the queue behind Lucifa, and the standing position was very close, at least he could see clearly the purple-red vortex and the abnormal changes.

Looking at the vortex that was spinning faster and faster, his heart couldn't help but feel nervous. Li, brothers, I hope you can prepare in time. This time, it was really a massive invasion. If it doesn't work, you can run away. There is no need to die with the United States. With the ability of the demon, it is still not possible to cross the ocean. Whether it is going to Europe or your China, don't be nostalgic about this place of divine punishment.

After about ten minutes, Mark saw that sweat began to appear on Pilie's forehead. The purple-red vortex had turned into a purple-red light curtain. Finally, Pilie finished reading the last few syllables, and he also mentioned the output of mana to the maximum. With a bang, the entire spell finally ended. Pilie put down his hands and gasped. Mark hurried over and supported him. They looked at the entire magic circle together. The purple-red vortex and lightning were gone, leaving only a few thick blue light belts connecting the locations of the five magic weapons. Looking down from the sky, a huge blue pentagram enveloped the crater.

On the passage on the Demon King's side, a blue patch covered the entrance of the cave like a lake. The Demon Kings waved their weapons and laughed loudly: "Go, my subordinates, the world has opened the door to you, go and build your merits!"
