Elara, separated by a thin layer of leather, carefully studied the mural while tracing the patterns with her fingers.
After a while, when she had traced from the top of the mural to about halfway down, she noticed a few faint lines that didn't match the rest of the characters or scenery. These lines were very weak and almost impossible to detect.
She paused, feeling the area again, and confirmed that there were indeed faint, winding, raised lines in that part.
"Uno, bring me some paper and a brush."
Uno brought over the tools, and Elara, while feeling along the faint lines, started to carefully sketch the patterns onto the paper.
Because the mural was too long and large, and the faint raised lines often blended into the uneven three-dimensional images, they were very hard to spot.
Elara slowly traced and sketched from one end of the mural to the other. Along the way, she made several mistakes due to the irregular lines of the image itself, so she had to stop and revise her sketch a few times.
By the time she finally finished sketching the entire mural and marked all the correct raised lines onto the paper, half an hour had already passed.
After confirming that she had drawn the last faint raised line correctly, Elara stood up and let out a light breath. She took out Oswyn's external detoxifying powder from her medicine pouch, rubbed some on herself and Uno, and then removed her gloves and looked at the drawing.
The large sheet of 3A paper was nearly filled with her sketch.
Line after line, whether straight or curved, were densely packed. Every few dozen meters or so, five or six parallel lines would run into a fence-like raised section, then pass over it and continue in parallel again, bending toward the next fence.
Elara looked at the overlapping, intricate lines that left hardly any blank space on the white paper. She stared at the extremely complex curve patterns for a few seconds, then her eyes widened slightly. This complicated network of lines looked familiar.
She frowned slightly, pulled Uno to a cleaner spot, and sat down. Then she lowered her gaze and stared intently at the line drawing in her hand, thinking carefully.
After studying it for more than ten minutes, Elara suddenly came to a realization. She looked at the line map in her hands with surprise. Didn't this look exactly like a massive and complicated circuit diagram?
Those parallel lines were densely arranged circuits, and the raised fences every few meters were the most basic resistors.
With this thought in mind, Elara examined the line drawing again from the perspective of a circuit diagram. The more she looked, the more it made sense.
Her eyes couldn't help but widen slightly. So this divine gift really came from some kind of future technology?
The line diagram in her hands, or rather, the circuit diagram, was incredibly complex and packed. Anyone without a background in physics would find it nearly impossible to understand.
Luckily, in her past life, Elara had been the CEO of the Xia Group. Even though her major wasn't in physics, the Xia Group owned many technology companies working on advanced cutting-edge projects.
As the top decision-maker, she had to understand the reports given to her on breakthroughs in various fields. So she had studied a wide range of subjects, including both professional and non-professional high-level technologies.
Now, looking at the complex and packed circuit diagram in her hands, Elara, after the initial surprise, became more focused and serious.
She studied it carefully for another ten minutes or so and finally found a tiny main switch hidden in a very inconspicuous spot on the giant circuit diagram.
However, the circuits around the main switch were all disconnected. Only someone highly knowledgeable in circuits could find the correct paths among the hundreds of tangled wires and connect the positive and negative terminals correctly.
Elara rubbed her eyes, which were getting tired from staring too long. She looked at the big tangle of crisscrossing wires and circuits on the wall and felt a headache coming on.
It gave her the same kind of chaotic and frustrating feeling as seeing a messy high-voltage main circuit tangled up back in her past life.
She slightly pressed down the complicated thoughts in her mind.
Elara stood up and walked toward the tiny main switch that Uno had found.
The main switch, about the size of a grain of rice, fit perfectly into the eye of a figure in the mural.
It looked completely normal and not out of place at all.
If Elara hadn't drawn this circuit diagram herself and didn't possess deep and rich knowledge, anyone glancing at it would've just thought it was a normal detail in the figure's eye.
After feeling for the small indentation like a grain of rice, she put her gloves back on and started feeling around the complex and chaotic circuit diagram surrounding the main switch.
These messy and chaotic circuits were actually hidden in the mural's strands of hair, animal fur, and the tangled vines of plants.
When she gently tugged on them, they actually moved.
Elara let out a light breath and reached both hands into the tangled mess of wires.
She moved back and forth among the hundreds of fine wires twisted together, searching carefully.
Combining that with the small connecting ports around the indented main switch, she slowly separated the correct wires from the tangled mass and connected them one by one.
It was quite a task.
Her eyes were starting to blur from staring at the complex web of wires when she finally connected the last wire to the tiny main switch.
She let out a light breath and stepped back, putting distance between herself and the mural, which now looked different due to her modifications.
Uno, behind her, also stepped back at the same time.
"Breath-suppressing medicine, antidote, internal energy recovery pill, give me two of each. Take two of each yourself too."
After Uno took out the pills from the pouch and fed them to her, he took his own.
Once they had made all the necessary preparations, Elara gently raised her hand and pressed the rice-sized switch that was now connected to the circuits.
Click.
In the next second, a heavy clicking sound echoed.
It was like an ancient and decaying mechanism that hadn't moved in tens of thousands of years slowly starting to turn.
The deep clunking sound echoed from the depths of the corridor.
Suddenly, the dim corridor lit up brightly as if light had shot in through every corner and crack like a leaky sieve.
The whole corridor became as bright as daytime.
At the same time, the gunfire and explosions Elara was so familiar with in her past life, but now felt distant and strange, suddenly burst out inside the corridor.
The military was shouting. Bombs were roaring.
The battlefield's explosive and terrifying noise roared through the entire corridor.
"Master, be careful."
Uno appeared behind Elara the moment the sound erupted.
He tightly wrapped his tall body around her and frowned deeply, his sharp eyes staring at the suddenly alive walls around them.
His sharp dagger was held out protectively in front of Elara.
After Elara barely adjusted to the sudden burst of bright light, her eyes finally saw the completely changed scene around her.
The murals that once had a mystical look had now become a huge, continuous screen.
Inside the screen, the previously raised and sunken lines had all vanished.
The images of deities, beasts, and mountains had also disappeared.
In their place were moving modern war videos playing like holographic projections.
