Bright Sword: I built Italian cannons for Li Yunlong

When Zhou Zhen woke up from his deep sleep, he found himself in a mountain valley.

He just looked up, trying to see where he was.

A loud explosion rang in my ears.

boom!

A shell exploded fifty meters away from Zhou Zhen.

"These are real artillery shells."

As a PhD in chemical engineering, Zhou Zhen was naturally very clear about the effects of TNT explosions.

"I just took a nap, how did I end up on the battlefield?"

This scene completely panicked him, and he no longer had time to think about questions like "Who am I?" or "Where am I?"

He quietly peered down the ravine toward the direction from which the explosion had come, and saw two groups of people fighting in the distance.

Stray bullets were flying all around him, and he only dared to glance at them briefly, not even being able to make out the specific styles of the clothes worn by either side.

Intense fear consumed his mind, making it impossible for him to think calmly.

At that moment, through the sounds of gunfire, the faint roar of men could be heard coming from the valley.

"You spendthrift, why don't you use it more sparingly..."

"Commander, you have to speak from your conscience..."

"When the Japanese attacked just now, you were the one who shouted the loudest."

"Pillar, take out that heavy machine gun."

A little while later, they wanted me to shoot down that grenade launcher.

"Now you're denying it again."

"..."

Hearing the somewhat familiar conversation between the two, and recalling the colors of their clothing that he had vaguely glimpsed earlier, he finally realized what was going on.

"Damn it, this has put me in the world of Bright Sword."

Before he could think any further, another shell suddenly exploded not far from him.

The shockwave from the explosion instantly knocked him unconscious again.

When he woke up again, he was already at Li Yunlong's regimental headquarters.

At this moment, Commander Li, with his thick eyebrows and big eyes, was smiling and looking him up and down.

"You're so delicate and fair-skinned, you must come from a wealthy family. What are you doing here? Do you know that if you hadn't been lucky, you would have been blown to bits by now?"

Li Yunlong's voice was loud, and his entire demeanor was rather carefree and casual.

Zhou Zhen looked at Commander Li in front of him. Although he was thin and had dark skin, his eyes were exceptionally shrewd.

As someone who came later, he knew all too well that this seemingly carefree Commander Li was more cunning than any hole in the city wall.

The other party was clearly testing his intentions and identity.

But thinking about it, it makes sense. If someone dressed in strange clothes suddenly appears in someone else's war zone, it's already a favor that they don't kill you as a spy because you're a fellow countryman.

Fortunately, he had already planned his response.

"My parents are overseas Chinese in the United States. Now that they have heard that their motherland is in trouble, and I have completed my studies, they want to come back to serve their country."

"My ancestors were originally from Shanxi, so I thought I'd go back to my ancestral home first. I never expected to encounter the Japanese sweep, and I got lost while hiding all the way. If it weren't for Commander Li's rescue, I probably would have died in the Japanese artillery fire."

After saying that, Zhou Zhen was about to get up and salute Li Yunlong, but Li Yunlong grabbed him and said, "You're injured, so don't bother with all this formality. I, Old Li, don't fall for it."

"The Japanese are wreaking havoc throughout Jinzhong right now; it's not a place for a scholar like you. Once your injuries have healed, I'll arrange for someone to send you out."

Clearly, Li Yunlong did not completely believe Zhou Zhen's nonsense, but he also did not ruthlessly let him leave with his injuries.

However, having some time to maneuver is also a good thing.

Upon hearing this, Zhou Zhen agreed, following Li Yunlong's suggestion.

He was willing to risk his life to travel through time, even if it was to a parallel world, to help his predecessors and teach those Japanese devils a lesson.

The best way to solve this problem is to prove your worth.

As a chemistry PhD, the quickest and simplest way for him was to improve explosives.

However, given his sensitive identity, Li Yunlong would never, and dared not, allow him to approach the military industrial area.

He could only look for a breakthrough elsewhere.

However, for a moment, he couldn't think of what Li Yunlong urgently needed.

Zhou Zhen felt increasingly anxious because he had a wealth of knowledge but nowhere to use it.

As he pondered, he wondered why he had transmigrated to the world of Bright Sword.

He only remembered that he was scrolling through Douyin that day when he happened to see Fan Ming's performance on the theme of dialogue across time and space.

He said, almost as if possessed, that if he could go back in time, he would dedicate his entire life to learning so that more of his ancestors could witness the future victory.

Who would have thought that when I woke up, I would actually have traveled through time?

Just as his thoughts were drifting away, the door creaked open.

A young soldier walked in carrying a tray of medicine.

He looked no more than fifteen or sixteen years old, his cheeks were red from the wind, and his eyes were clean under his military cap.

"Comrade, it's time to change the dressing," the young soldier said softly.

Zhou Zhen snapped out of his daze and obediently turned around.

He was hiding in a ravine at the time, and the shells landed far away, so his injuries were not fatal.

However, due to the impact of the powerful blast wave, he suffered not only abrasions but also several fractures.

The young soldier awkwardly unwrapped his bandages, but he was extremely careful despite his lack of skill.

Once the bandage was completely removed, before Zhou Zhen could even prepare, he used a cotton ball soaked in alcohol to clean the wound.

Aha...

Zhou Zhen was in so much pain from the alcohol that he grimaced.

His whole body tensed up, and the scene was exactly like the scene in "The Unknown" where Zhang Yu was being disinfected.

It took him a while to recover, and he asked with lingering fear, "Young comrade, do we disinfect the wounded here with alcohol?"

"Yes!" The young soldier nodded as he wrapped the bandages around his neck.

"The medical team said this is the only one that works."

Zhou Zhen asked a few more questions and learned that the base area was extremely short of supplies, and the so-called "alcohol" was actually mostly high-proof liquor collected from the people and then purified.

Due to its low purity, its disinfection effect is limited.

Although Zhou Zhen was not a medical professional, he knew that alcohol, due to its strong irritant properties, would not only worsen the pain but also affect wound healing.

In modern medicine, iodine solution, which is less irritating, has long been used for disinfection of large-area wounds.

At this moment, he finally came up with an idea to prove his worth.

Using his expertise from his previous life, he synthesized a disinfectant that could replace alcohol.

This would not only help these revolutionary fighters, but also prove his own worth, making Li Yunlong reluctant to let him leave.

This matter needs to be handled quickly, because he knew that Li Yunlong's defeat of the Sakata Brigade violated orders from above, and he would soon be dismissed and transferred to the clothing factory.

Many of his subsequent experimental ideas probably seemed like wild fantasies to others.

Compared to the steady Ding Wei, Li Yunlong, who is bold, adventurous, and unafraid of rules and regulations, is clearly a better fit for him.

He had to hurry and gain Li Yunlong's trust before he was transferred, so that he could go to the clothing factory with him.

So the next day, he asked the young soldier Niu Er to take him to the logistics wounded soldiers' ward for an on-site inspection.

However, the scene in the wounded soldiers' camp shocked him.

This is a converted earthen temple, and dozens of wounded people are lying densely packed in the main hall.

One of the soldiers with a large wound was gritting his teeth as the medic stitched up his wound. Due to the lack of anesthesia, the soldier was screaming in pain.

He fainted from the pain when the military doctor disinfected his wounds with alcohol.

Eighth Route Army soldiers are also made of flesh and blood. Even with a strong will, there is a limit to how much physical pain they can endure.

Zhou Zhen's heart clenched, and he cursed inwardly, "Damn those Japanese!"

He suppressed his emotions and subtly inquired about the logistics and supplies situation of the regiment.

The result was not much different from what he expected. Under the current conditions, it was impossible to produce hydrogen peroxide, or even the commonly used iodine solution or iodine tincture.

Both the iodine and PVP needed for povidone-iodine, and the ammonium persulfate and other raw materials needed to produce hydrogen peroxide, were difficult to obtain under the existing conditions in the base area.

Therefore, he had to think of new solutions, but since he was not a medical professional, he only knew a few common types of disinfectants.

Little did he know that his inquiries about supplies had already alerted Zhang Dabiao.
