"Heave-ho! Heave-ho! Whew... I'm exhausted!"

Vera spoke calmly, looking exhausted, as she followed Illa out of the mine. She complained, "Honestly, why make a weak woman... a lich like me move clay and stones?"

"Ugh...ugh...I'm exhausted. If my back breaks, I'll break yours too."

As Vera said this, she clutched her lower back, looking like she was saying, "Oh dear, my back is about to fall apart." Well... by human standards, Vera is indeed quite old.

But you can't say that in front of her.

"..."

However, Illa did not respond to Vera's words. He just looked at her with disdain, then at the math olympiad servants behind her. He waved his hand, signaling Vera to direct the math olympiad servants who were carrying things, and said, "Put it down."

"Oh~"

Vera straightened up easily and answered obediently, waving her hand in imitation of Illa's gesture. Then, the math servants put down the materials they were holding.

Small Bookstore

So why is he putting on such a show when he hasn't done anything at all?

Yinla shook his head helplessly as he recalled the cement making process... First, the clay was calcined at high temperatures, and then it was mixed with quicklime obtained from high-temperature calcination of limestone in a 7:3 ratio.

According to the descriptions of the ancient times in previous textbooks, special furnaces were generally used for multi-layer firing to achieve the appropriate temperature in one go... To be honest, this temperature was probably quite high.

However, it wasn't that troublesome for Inra.

"First Wing Pillar - Crimson..."

As Yinla recited the mantra, nothing changed behind him. He paused for a moment under Vera's gaze, then awkwardly corrected himself: "Flying Wing Pillar - Tikkap - Wing Manifestation!"

As the succubus's wings appeared behind Yeyira, he looked at Vera, who had a puzzled expression, and explained, "I haven't asked Satan Ye about Mana before, um... I'll be right back."

As she said this, Yinla quickly faded and disappeared into the air.

No matter how Vera looked at it, it was an extremely absurd thing. She stood there, staring at the spot where Yinla had disappeared, lost in thought... Even if Tikkap's soul had entered Yinla's body, it should be impossible for him to use Tikkap's talents as well.

There must be some reasons that Vera doesn't know, or even that Ira doesn't know, that led to the current situation... Although it's hard to imagine this is a bad thing, it's always good to understand it thoroughly.

"Ah, I'm back."

In less than a minute, Yinra, with two pairs of wings on his back, returned to Vera's side from the void. The wings of the crimson dragon and the wings of the succubus on his back were distinct yet perfectly integrated.

Simultaneously unfolding two pairs of wings... Fortunately, this ability was displayed when Inra joined the Demon King's territory; otherwise, if it had occurred during a time of hostility towards demons, everyone who opposed him would probably have gone insane.

It wasn't the power Inra displayed that drove her mad, but rather the very thing Inra's simultaneous unfolding of her two wings represented—a collapse born of fear for the future…

Perhaps if Illa puts on a show at the end of the war, appearing stronger, the Empire could win directly.

As soon as Yinla appeared, the temperature in the surrounding air began to rise significantly. Blazing flames swirled around him, spitting out the surrounding air and making everything around him scorch.

"boom!!"

With a simple flick of Yinla's finger, dangerous flames instantly burst forth, the scorching crimson carrying clay and limestone into the sky, where they burned, tore apart, and pulverized.

Then the flames subsided, and as Yinla dispersed the flames, fine dark gray dust fell to the ground, forming a small mound. It was clear that the pile of things still retained a considerable heat... So, this is what Yinla wanted?

"Vera, get some water."

As Yinla said this, Vera didn't understand what Yinla meant. She looked at him suspiciously and asked, "What water? How much water? You're not going to make me use celestial manipulation again, are you?"

Yinla thought about it for a moment and decided against it. He said, "I'll do it. Actually, a regular water-making spell is enough. It's too much trouble for you to chant, and you can't chant at high speed... Third Wing Pillar - Lich - Wingspan!"

Listening to Yinla's voice and watching him spread his lich wings and start creating water to stir things up, Vera felt a little hurt... Although what Yinla said was true, it was still a bit hurtful.

"I'm not a battle mage, and I haven't studied combat techniques. Unlike you guys, all you think about is skirmishes."

Vera muttered in a low voice as she watched Yinla switch back to the headless knight's wing pillar, using the condensed lance and the constantly rotating mana to stir it... Soon, the dark gray powder turned into dark gray mud.

"So that's the cement you were talking about? That's a great name, simple and easy to understand."

Yinla nodded in response to Vera's assessment. His body erupted with black mana, instantly shattering the cement in front of him. He then roughly and violently smeared the cement all over the dirt road in front of him.

"That's fine. Cement takes a long time to harden, and we'll have to wait and see if it works."

As Yinla spoke, he simply retracted the wings on his back, gestured to Vera, and asked, "Given the current situation, what proportion of anti-magic stone powder should be added to block detection and analysis spells?"

When Vera heard that she was talking about her area of ​​expertise, she became a little serious. She pondered for a moment and said, "The materials are a bit too pure, which might make things a little difficult. Let's discuss this after it solidifies."

It seems that, for the time being, Vera is not very confident in making a judgment.

Yinla wasn't in a hurry. He could only nod and give simple instructions: "Then set up a subtle barrier to prevent others from getting close. I'll go find some things to build a shed to keep out the rain... I'll come back to check on it in about ten days."

"okok!"

Vera crossed her arms in response, seemingly quite proud as she confidently declared, "My knowledge of barriers and rituals, I'm not bragging, I can say it's unparalleled!"

Yoonra: "Okay, okay~"

Vera: "Hmm? Why do I feel like you're just giving me the runaround?"

Yinla: "An illusion, an illusion."

——————————

"This is cement?"

The human woman squatted down next to the cement, studying it as if it were her own backyard, almost poking and prodding it with her fingers.

"Is it some kind of composite material that is easy to shape but becomes very hard after drying? Illa has given us another pleasant surprise."

Vereesa looked up at the sky and couldn't help but laugh out loud: "Hahaha, why is everyone looking this way? A whole bunch of curious little ones~"

"..."

Curious kids: "..."

That cannot be refuted.
