The chaotic and terrifying purgatory is considered a subordinate plane of the main realm.

According to the records left behind by the legendary adventurer Shak Xu, Purgatory is located in the deepest part of the earth, a sea of fire that burns with endless flames.

However, according to Amosich's description, Purgatory is more like a vast and intricate underground labyrinth, with unquenchable black and red flames gushing in some places, and in other places it has been in darkness for thousands of years, never seeing the light of day.

"Shak Xu is close to the truth," the Fire-Eyed Raven explained, standing on the tree, with that peculiar hum, "the sea of fire he arrived in was actually the sky above our heads. ”

"The sky is burning with endless flames?" imagined the sight, and Allegri was a little surprised, "Isn't it going to be a problem?"

"Question?" Amosic tilted his head, "There will be occasional rain of fire, light rain is fine, if it is a violent 'meteor rain of fire', then it will inevitably have some casualties." ”

"Meteor Rain...... Allegri muttered, "it turns out that the rain in Purgatory is all 'forbidden spells'." ”

"It's not as scary as you think, there are usually enough signs in advance to remind us to avoid or divert," Amosic laughed, "By the way, how are the preparations for the 'Iron Gate'?"

"These are the teachers' responsibilities, I don't know. Allegri said casually.

"Really?" Amosic snorted suddenly, "That old fellow, you are responsible for everything, and he doesn't know anything about it?"

"You don't know the difficulty of opening the 'Iron Gate', of course I need a lot of time to plan. Herseus's old voice rang out.

"But didn't you open it once?" argued Amosic.

"What was the situation back then, as a legendary magician, I controlled one of the Nine Towers, and I had countless capable people under my command, and it took so long;" Herseus snorted, "Now this kid is a high-level like a weak chicken, he doesn't even have a root tower, and his subordinates are all old, weak, sick, and disabled women and children......

"Am I really that weak, dear teacher......" Allegri, whose self-esteem was badly wounded, argued weakly.

Allegri had expected the "Iron Gate" to be a huge portal, at least much larger than the cast arch that the Church of Light had made in Valhalla.

And his task is to take Amosic to the Iron Gate under the siege and interception of the Church of Light, so the mission is successful, and he receives experience and monetary rewards.

"Childish," Herseus scoffed at his idea, "If the 'Iron Gate' is so easy to find, with the strength of the Church of Light, won't it be broken directly, and left for people to open again?"

"Yes. Allegri nodded helplessly.

"The 'Iron Gate' is indeed a door, somewhere between the physical and the void, and it does have the effect of a portal. Amosic explained.

"I don't understand. Allegri shook his head.

"With the strength of the legendary magician of Shak Xu, how could he be blocked by that sea of fire?" added Herseus, "In that sea of fire, there is actually a prohibition that he can never overcome. In fact, between Purgatory and the World Realm, there are two layers of separation between the power and the forbidden realm, the deep layer of earth under our feet is one, and the sea of fire above purgatory is another. ”

"Demons can break through the sea of fire, but they will be stopped by the prohibitions in the earth, and creatures in the earth-like realm can enter the earth, but cannot pass through the sea of fire, so theoretically, the two will never be able to communicate. ”

Amosic and Herseus are simply a cross talk combination, you explain it word by word.

"So what?"

"So what we have to do is to find a place," Herseus said, "find the area where the strength is weakest in the soil layer prohibition, summon the 'Iron Gate', and then knock on it, and the demon can concentrate its strength to break through this gap, establish a stable two-way portal, and enter this world in a steady stream." ”

"You are not so much a knocker as a scout, identifying weak points in the enemy's line of defense and signaling the army to break through it. Amosic added.

"How do I feel less like a scout than a spy?" Allegri interjected in a gloomy mood.

"Oh, isn't the Church of Light your allies too?" Amosic snorted.

"Actually, our first task is to find the weak point in the ban," Herseus changed the subject and eased the atmosphere, "Allegri, I will test you, where is the easiest place to find a breakthrough?"

"A weak spot in the soil?" Allegri wondered.

"Yes, this is a very difficult thing, I spent three years reading books, and traveling half the continent—" Herseus said with a look of pride.

"Is it a crater?" Allegri blurted out with a sudden stir.

"......" Helthewston shut up.

"Allegri, aren't you in a good mood?" said Bai Ji as he looked at him earnestly during dinner. As a savage, she has a natural keen intuition.

"It's fine. Allegri nodded pretentiously, and returned to his room without eating much under the worried gazes of everyone.

When he first reached a cooperation intention with Amosic, it was mainly the guidance of Herseus, and he didn't think too much about it, but he basically agreed.

On the one hand, he was being closely pursued by the church at that time, and it was naturally great to get a help, and on the other hand, the invasion of the demon army was enough to divert the attention of the church and relieve Nacini of the two-pronged pressure.

However, after solving the looming crisis of Gregory in one fell swoop, after temporarily having a chance to breathe, he couldn't help but start thinking seriously.

Is it a wise choice to lead the invasion of the demon legion?

He couldn't help but shudder a little as he imagined endless demons pouring out of the portal, rivers of blood flowing everywhere he went.

Outside the window, in the twilight, the turquoise grassy slopes gradually spread, intersecting with the plantations in the distance, revealing a beautiful and quiet scenery. And what he did was likely to destroy all this in a black-red flame, and he suddenly felt a sense of fear for some reason.

With the help of Amosic and Herseus, knocking on the door of iron and fire seemed to be a matter of victory, but he couldn't help but cringe a little.

"Don't overthink it, my student. Herseus's voice was rarely so serious and serious.

"Teacher......" Allegri whispered.

"Sometimes, you just don't have any other choice," Herseus said slowly, word for word, "even if one day you become a legendary magician, and your strength is not strong enough to change the entire world, you will inevitably have to make a choice that you are not willing to make." ”

"Teacher, you ...... back then Under what circumstances did you knock on the 'iron door'?"
