Overlord: Start from the Goblin Lair.

Chapter 179: Mage's Chamber
This cellar must have had a ladder in the past, but due to its age, the wooden ladder could not stand the test of time, so Ron and his friends had to jump directly down from it.

It's not that the Feather Fall Technique can't be used, but given the time it takes to hold the ceremony, Ivy and the others would have enough time to build a human ladder, so it would be better to just jump down.

"This shows the benefits of my potion," Ron said in the cellar, moving his sprained ankle and stuffing the empty medicine bottle back into his backpack. "If I were to use ordinary healing potions, I would definitely not want to use them."

"Why don't I cast a spell to heal you?" Victoria held up a candle with an eternal flame to illuminate the surroundings. "Even the cheapest healing potion is priced in gold coins."

"There won't be anything here anyway..."

The pastor raised the candle, but her voice suddenly stopped. When Ron and others came over to take a look, they saw that her eyes were fixed on an old drawing on the wall, unable to move her eyes away for a long time.

"This is..." Ron and Sylvia were also stunned after seeing it. This drawing was obviously processed by magic, so that even after such a long time, the ink on it was still clearly visible. But it was also because of this that the casters were so shocked!
"What is this?" Driver was confused. He looked up at the wall and felt that it was somewhat familiar. But as to why it was so, he didn't know and was not interested in knowing.

"Is this a spell model?" Ron muttered, "It just seems to be unfinished."

"There is no doubt that the former owner of this place must have been a powerful wizard," Sylvia nodded in agreement. "Only spellcasters who can master advanced spells like Creation (Five Rings) can construct their own spell models and write their own spellcasting rules."

"Most of these people have left spells with their names in the history of each world," Victoria praised. Although she did not have such an opportunity, it did not prevent her from paying respect to these famous legendary figures. "Tasha, Tamsen, Mayofu... They live in every corner of the world, in every spell book, and in the mouth of every arcane spellcaster."

"Then what are you sighing about?" Driver looked at Victoria unhappily, "Aren't we supposed to be on the same front?!"

It's obvious that you also cast divine spells like me!
Victoria gave the goblin a look that said, "Who wants to fight on the same side with you?" and continued to stare intently at the writing on the drawing on the wall: "This elven wizard...what kind of magic does he want to create?"

"Protection, without a doubt - look at his calculations and model sketches here," Ron borrowed Sylvia's cane and pointed at a few handwritings on the drawing, "The target effect of this spell should be..."

"Push the surrounding enemies away to give the caster more space to cast further spells," Sylvia added, "Then he must create a spell that can be activated quickly like the shield spell, otherwise it will be meaningless."

"It also has to be strong enough and powerful enough, at least far stronger than the caster himself." Ron tried to take the blueprint off the wall, but when he touched a corner, it instantly turned into ash, forcing him to give up. "It even has to target enough targets. It's obviously not enough to only target one target."

"The mage even tried to add some extra energy to achieve the effect of hurting the enemy at the same time," Exuri glanced at him with disdain. "He was too greedy and ended up with nothing good. This model was obviously beyond his ability, so he couldn't complete it until the end."

"Maybe I can write it down," Ron thought for a moment and opened the preface to the weaving method. "I think the idea is good. Maybe it can be used as a reference in the future."

The preface to the weaving method helped him remember every detail on the entire drawing. After he had memorized everything, the drawing seemed to be unable to hold on any longer and turned into a wisp of flying ash with the breeze blowing in from the entrance.

"The magic on it resonated with the foreword of the weaving method and eventually ran out of power," Ron explained, reaching out to touch the wall behind the blueprint. "What's going on here? It looks like a wooden board."

"What's so strange about this?" Yelena said casually, "Even a house made entirely of stone can have wooden shelves." "No, it seems to be hollow inside?"

"Get out of the way, let me try and we'll know." Sera pushed Ron away, and without taking the sword, she went up and elbowed the wall, shaking the entire basement.

"Even a stone wall can't withstand your blow." Ron spat a few times. Apart from Sera, he was standing closest to the wall. As expected, there was nothing behind the wall, and the accumulated dust almost filled him up.

However, at this moment, Ying Ling's face changed instantly.

"Do you smell a smell of... sulfur?"

"Brimstone...you mean Hell?!"

Without time to answer, Yelena didn't care about the smoke and dust that had not yet dissipated, and rushed in directly. At the same time she entered, a huge pattern on the wall of the secret space behind the wall lit up with a scarlet light!

"The spiked onyx and the crooked horn crown, this is the symbol of Asmodeus, Lord of the Nine Hells!" Constance exclaimed, "I've seen this symbol before!"

"Are there devil followers in Rose City?" Ivy raised her eyebrows.

"There are devil believers everywhere. After all, they are closer to mortals than gods." Victoria curled her lips. "The elven wizards here are actually worshippers of the Devil Duke?"

"No wonder the Mimic was able to pick up soul coins nearby," Sylvia walked closer curiously. "It's nothing. This should only have the function of emitting light. I can't sense any inducement or corrosion."

"That's because I turned it off," Yelena snorted, "Why else do you think I came in first?"

She walked to a table that was obviously used for prayers and pulled out a notebook from the dust on it: "Written in the language of Purgatory, for fear that others would not know that he was a believer in the devil."

"I guess most people wouldn't come here," Constance covered her mouth and nose with a handkerchief and looked around the secret room. "Yes, that's right, this is the layout..."

"What did you say?" Ivy glanced at her intentionally or unintentionally.

"No, nothing." Constance was stunned for a moment, then quickly returned to normal. "Like I said, there are also devil followers in Rose City. I went to the scene to join in the fun. It's very similar to the decorations here. Very similar."
