Cannon Fodder in the 1970s: With a Sign-In System – CH240

Chapter 240: Feeling Physically Drained

System hadn’t managed to record anything in the love observation notes, but it was very pleased to see its host diligently researching and improving herself. A great sense of accomplishment filled it.

Its host had started to rely on herself—it made System happy.

Meanwhile, Ning Xiyue had to provide all the medicinal ingredients herself for the remedies she was experimenting with.

Some ingredients were in her space, but others weren’t planted there and had to be sourced another way.

She wasn’t in a hurry. She still had system points and the system’s recycling station. With points, she could purchase the herbs she needed from the recycling station.

Ning Xiyue opened the system recycling station and bought the herbs and materials needed to research the bone- and tendon-repairing medicine.

In her study, she focused on refining the essence from the purchased ingredients. System, the little turtle, propped its chin on the desk, watching its host work diligently, its tiny eyes full of admiration.

Whenever she paused, she would see the satisfied little turtle beside her, feel a warmth in her heart, and continue her work.

As the saying goes: when you’re exhausted at work, there’s always a little companion watching over you.

One person, one turtle—no interference, just companionship. Peaceful days.

Working in her study with time sped up a hundredfold was like a paradise for a researcher: losing all sense of time, fully immersed in experiments.

Trying one herb after another, Ning Xiyue lost track of time—perhaps 200 hours, perhaps more—but she finally concocted a bone-and-tendon repair powder, though she didn’t know yet how effective it would be.

Brimming with energy, she took the powder to the testing robot. She programmed the robot to simulate a broken right leg with severed tendons.

Then she applied the powder to the robot’s right leg and awaited the result.

One minute later, the results appeared:

“Ding! Effect is poor. Side effects present. Side effects duration: seventy-two hours.”

The robot repeated, “Side effects present,” over and over.

Ning Xiyue first stared at it in disbelief, then covered her mouth and laughed.

“Good deed today -1, -2, -3…”

She tried to hold back, but couldn’t resist.

“Hahaha!”

It wasn’t that she was being immoral—she just wanted to contain her laughter—but she couldn’t stop.

The robot’s face, normally human-colored, had turned completely black after using her medicine. Only its face was black; the rest of the body remained normal.

She couldn’t stop laughing. The side effect only appeared on the face—was it poisoned black?

It instantly reminded her of the black-faced meme.

After laughing enough, Ning Xiyue calmed down and switched to a serious expression, determined to investigate the cause of the side effect.

Poor efficacy was one thing, but such a side effect could be disastrous on a real person. She needed to improve it.

However, the current batch could still be kept as a formula and used as a poison against bad people.

Ning Xiyue tested the remaining powder in the analyzer, identifying the problem.

Inspired, she replaced two strongly potent herbs in the original formula with others of similar efficacy but milder properties.

Seeing the newly revised formula, she started a fresh round of preparation, working smoothly and efficiently.

Soon, she produced the improved powder and tested it again on the robot.

“Ding! Effect moderate, no side effects.”

Ning Xiyue breathed a sigh of relief.

No side effects was what mattered. The potency could be gradually refined, carefully polished, and eventually she would achieve an excellent result.

For now, she decided to switch gears and relax by working on an eye cream for reducing dark circles.

Beauty and skincare were fun for Ning Xiyue, much like weaving crafts—she enjoyed it.

She took out the imperial secret book and studied it.

Combining the page on protecting the skin around the eyes with her knowledge of herbs effective for dark circles, she created an entirely new eye cream formula.

Looking at her formula, Ning Xiyue was eager to try it.

She returned to the system recycling station to gather the materials needed for the cream and started making it based on her formula.

She didn’t know exactly what would come out—the process was experimental.

Because her formula was rough and lacked precise steps and measurements, she relied on intuition and feel.

This was her favorite part—the process was fun and exciting.

Failure after failure didn’t dampen her enthusiasm for making the cream.

After perhaps another 200 hours, Ning Xiyue finally produced a decent-looking eye cream.

Excited, she tested it on the robot, simulating dark circles under the eyes. She applied it carefully to both eyes and watched intently for the results.

“Ding! Excellent effect. Continuous use for one month can effectively remove dark circles. Two months’ use can reduce fine lines around the eyes. Long-term use keeps the eye area youthful and hydrated, like an eighteen-year-old’s skin.”

Perfect.

Ning Xiyue couldn’t stop smiling. The test report confirmed the effectiveness of her eye cream. She was satisfied.

“Ah, it’s getting late. I need to go sleep—staying up late harms the kidneys.”

It was already midnight. She had been on the kang for five hours, meaning she spent about 500 hours in the study.

She felt completely drained, as if her energy had been sucked out by a demon.

But creating these two remedies had been worth it.

Ning Xiyue looked at the eye cream in her hands, heart full of joy. She left the space, applied it around her eyes, and finally closed her eyes to sleep peacefully.
