I became the slime toy of the evil dragon girl?

She scooped Ian up, not caring about her own wetness, and prepared to walk towards the poolside, dripping wet. "Come on, take me to see!"

"Wait! The clothes!" Ian shouted.

Vivian looked down at herself, tilted her head, and said, "Oh!"

She casually grabbed a black tulle skirt from the poolside, put it on, and didn't wear it properly. She just wore it loosely, tied the straps casually, revealing a lot of her collarbone and shoulders.

Barefoot on the stone slabs, a trail of wet footprints was left behind.

Her black hair was still dripping wet, the water droplets sliding down the ends of her hair, onto her shoulders, and into her collar.

She didn't care at all, and walked out with Ian in her arms.

"Hurry, hurry!" she urged, her golden vertical pupils filled with anticipation. "I want to build a happy house with magic stones!"

Ian was held in her arms, feeling the warmth of her body through her wet silk tutu and the water droplets dripping from her hair.

A flame rose from Vivian's body, instantly evaporating the moisture from her soaked clothes.

Strangely, Ian himself was completely unharmed, despite wearing the tutu.

Vivian's got something...

……

The test site was chosen in an open area at the foot of the Emberthroat volcano.

Ian directed Angry Horn and several of his minotaurs to dig pits and move limestone and clay.

Charles helped find these materials. Although the old butler was completely baffled by the idea that "the slime wanted to burn stones" and didn't understand the significance of burning stones, he still dutifully provided assistance.

The angry horn was holding a limestone the size of a head, its face clearly saying, "I don't understand, but I'll do it anyway."

He asked gruffly, "Mother Earth, can this stuff be smelted into building stones? Why not just use stones directly?"

"Theoretically," Ian replied, measuring the depth of the pit with his tentacles, "if I remember correctly, cement is a mixture of limestone and clay in a certain proportion, calcined at high temperature, and then ground into powder."

"Sounds like bread," Angry Horn muttered.

"Pretty much, just at a higher temperature," Ian said. "A typical kiln would need around 1400 degrees Celsius."

"Steal the young master?!" The angry horned bull's eyes widened in disbelief.

"That's why we need magic." Ian jumped to the edge of the pit. "With traditional methods, just controlling the temperature alone would kill 99% of the craftsmen."

But now I possess dragonfire! The temperature depends solely on how much magic I provide.

This reminded him of science videos he had watched on Douyin in his past life.

Modern cement production is a highly industrialized process, requiring precise control at every step, from raw materials to calcination, cooling, and grinding in the kiln. Any error in parameters such as temperature or material ratio results in defective products.

In this world, there are no automated instruments, no control or monitoring systems.

The craftsmen relied entirely on experience and visual observation of the flame color to judge the temperature, resulting in an absurdly large margin of error.

But Ian has magic.

To be precise, it has [Magic Vein Weaving LV.2].

Vivian sat on a flat rock not far away, legs crossed, with a large plate of fruit in front of her.

Lilith stood behind her, her silver eyes fixed on Ian, her expression complex, a mixture of wariness, curiosity, and a hint of "I'll see how you put on this act."

Ian took a deep breath, even though slimes don't need to breathe.

He started working.

The tentacles reached into the ground.

[Magic Vein Weaving] activated.

This time, he wasn't going to work on a simple temperature control system, but rather on a complete, otherworldly, magical version of a cement kiln system.

Ian drew a thick stream of fire magic from the direction of the volcano. He was familiar with this task, having done it many times before for the Dragonblood Wheat Field.

A thought crossed my mind.

Golden specks of light shimmered, and veins of light flowed.

The originally violent and unruly volcanic magic became docile and orderly, like a tamed wild horse, flowing smoothly along the preset path and automatically splitting into three streams. One stream served as the main heat source, with only [Dragon Flame] installed on it, while the other two streams provided auxiliary regulation.

"Huh?" Vivian stopped eating the fruit.

Lilith's eyes widened as well: "This... how is this possible?"

They could clearly sense that the source of the dragon flame's magic was not Ian, but rather... the air?

"Basic procedure, keep a low profile," Ian replied simply, and continued operating.

He wove a three-dimensional grid-like network system around the dug pit.

Each vein carries two spells: [Temperature Sensing] and [Detection].

This is not a simple constant temperature control, but a zoned temperature control.

Ian drew inspiration from the principles of modern rotary kilns.

The material undergoes multiple temperature stages inside the kiln, each requiring a different temperature. Initially, it needs to be around several hundred degrees Celsius, while during firing it needs to reach 1400 degrees Celsius, and finally, during cooling, the temperature needs to be gradually reduced.

Achieving this kind of gradient temperature control using traditional methods? That's just wishful thinking.

However, using the magic network, Ian can divide the same kiln into four temperature zones, each with its own independent temperature control.

He even included a material movement simulation within the framework.

Although there is no teleportation device yet, at least the flow of magic can replace the path of heat transfer.

Ian wove another thread, specifically responsible for mixing limestone and clay powder.

He installed two spells on it: [Vortex Magic] and [Water Mist], to ensure the materials were mixed evenly and to control the humidity.

Limestone needs to be crushed into powder, and clay also needs to be ground.

The angry horn used brute force to smash the rock into pieces, but it was still far from being reduced to powder.

Ian simply used magic to solve the problem. He directly used the [Earthquake] spell to create high-frequency shockwaves and also added the [Crushing Spell] to magically grind the materials in the pit.

Crushed limestone and clay are rapidly refined and mixed under magical vibration.

"This..." Angry Horn was dumbfounded. "Mother of the Earth, you really are making bread!"

"Huh? You want some?" Ian focused on his work. "The fineness and uniformity of the cement raw materials directly affect the quality of the finished product. This isn't about improving the taste."

"I won't eat it." Angry Horn shook his head.

The next step is very important.

Ian needs to monitor the situation inside the kiln in real time, but he can't stick his head into the pit, which is over 1,000 degrees Celsius, to see what's going on.

He adopted an indirect monitoring method.

Based on the temperature control network, he added several additional sensing networks and simply installed the [analysis] function.

These pathways do not directly participate in temperature control, but rather directly reflect the current state of the material through analysis.

This is essentially a magical sensor.

Analysis is undoubtedly a divine skill, but unlike spells like Fireball or Illumination, it doesn't simply require you to set it up and then let the magic run wild.

It also needs to designate someone as the feedback provider, and currently only Ian himself can receive feedback.

It's alright now, it's just an experiment anyway, and Ian can stay by my side.

But what if it goes into mass production later...?

This made Ian desperately want a terminal or some other medium that could carry information.

……

The whole process lasted nearly half an hour.

Ian's magic power was rapidly depleting.

Fortunately, his weaving efficiency improved after leveling up to LV.2, which reduced his magic consumption considerably; otherwise, he would have shriveled up like a dried slime by now.

Even so, he felt completely exhausted when he finished weaving the entire network system.

"It's done," Ian announced, the light spots inside his body dimming slightly.

Vivian jumped off the rock, walked barefoot to the edge of the pit, and curiously peered inside: "Is that all?"

"No, not at all. We just want to give it a try."

Ian extended his tentacle and gently touched the starting point of the main vein.

hum!

The entire cement kiln started operating instantly.
