The most dangerous scenario to travel through is not a post-apocalyptic world with zombies everywhere, or a horror movie with a few ghosts popping up at every turn, or one or two aliens of any kind coming over to wreak havoc in an unorganized and undisciplined manner. Rather, it's the battlefield.

As the boulder ambush passed, there was a large buzzing sound in the sky. A huge airship of eighty meters in length and twenty-five meters in diameter was suspended under a beam made of steel brackets, and below the beam hundreds of wire cables were suspended a mysterious instrument with various streamlined glowing lines and patterns that were very different from the silly and clumsy mechanical image of this steampunk world.

Renyu looked up at the mysterious object hanging under the airship, and suddenly saw a protective curtain of light in his eyes, lifting his mind. His health dropped at 1 percent per hour, and the decline would last for three hours. There is also a hint nearby: it is suffering from radiation.

"The miners who found this thing died horribly!" Petruzzo had said this before the boulder fell.The Mina Kingdom Faction Corps had clashed with the Governor, a local power in the west, because of this thing.Petruzzo thought that by arriving with the elite Mina Royal Corps, he would be able to force The Doge to give up his unrealistic fantasies, But Petruzzo was clearly wrong. The Doge has decided to go to war, and that beam of light just detonated explosives buried on the cliff, a long-planned war.

Huge cargo blimps hoisting this heavy load slowly flew off to the west, and large cruising combat blimps flew past the perimeter. Don't imagine the flying machines of this world with the structure of Earth's airplanes. These high-speed flying combat machines are a thin sealed iron skin forming a streamlined hull of more than ten meters, while on both sides are two oversized fans fan-like structure of the wings to form a strong thrust. Pushing this small flying machine to move.

Looking at the airbag proportions of the airship in the sky, and estimating the weight of the cargo, Renyu felt a sense of dissonance, a kind of strangeness that didn't feel physically common sense to a science student.Renyu softly muttered to himself, “The air pressure is definitely not normal, and perhaps the gravitational acceleration is low as well."

While Renyu was observing this marvelous steampunk world, Andrew on the other side was looking at a gallant young woman sprawled out on a flying machine. It had to be said that this type of piloting while naked outside of the craft, secured only by a few seatbelts, was definitely an act of that brave man. This was another important plot character, Lian Lana.

The western part of the continent is called “Vinci”, and the city-states of Vinci are all steampunk-oriented, but with different focuses. Mina in the eastern part of the continent is bordered by Alim, which is good at magic, so it uses the core of the magic crystals as the carrier of AI, and is good at using electricity and steam to drive the robotic soldiers. On the other hand, the Venucci forces on the western side of the continent are orthodox in mechanical technology, with famous weapons such as steam artillery, and as for the Pailata where Carlini is located, it specializes in air force. Now that Pylata, a city-state near Mina, is assisting the Venucci, it's a very poor political sign

Andrew nodded thoughtfully based on the later development of the plot. The landslide triggered by the explosion has dealt a major blow to Mina's army, and the harsh reality has taught the surviving travelers to be careful about living in a world full of dangers.

Even though Renyu had once cursed the Japanese online, he didn't gloat when he actually saw a being directly smashed to death by a huge rock, with blood constantly flowing out from its edges, he just had a sense of shock at seeing his kind die. Life is really very fragile...

The Japanese were not the only ones who died. Petruzzo's thigh was completely smashed and there was no possibility of treatment. His brother Giacomo took out a bag of colorful sand from his backpack, and Giacomo sprinkled the sand on the cross-section of his brother's broken leg, which dug into Petruzzo's wound and quickly healed it.

It's a steampunk world, but it's also a world where magic is prevalent.

Giacomo said, "Brother, I will kill Venucci and avenge you."

Petruzzo shook his head and said, “Mina will make the best mechanical prosthetics for me, but Giacomo, you're the only brother I have.” Looking at Giacomo's hateful expression, Petruzzo understood that trying to persuade his brother to give up that discovery was probably impossible. He could only ask General Kalini to go down with his brother..

A case of theft: this story is not rightfully on Amazon; if you spot it, report the violation.

At that moment one of the soldiers saluted the three and said, "Report sir, Vinucci's forces have been spotted approaching."

Renyu looked at the bottle of healing medicine assigned to him, which could be seen through the glass to be filled with glowing quicksilver. “This is healing medicine?” Renyu looks at the strange bottle with some uncertainty and turns his head to look around, noticing that the wounded soldiers with broken arms and legs open the glass bottle and sprinkle a bit of quicksand on their wounds, and the wounds immediately heal. Even if the arm was broken, as long as the broken arm was docked, sprinkled with quicksand, the fine sand wrapped around the docking wound and gave off a strange light, just like a halo was put on the arm, when the light dissipated and the glowing sand turned into ordinary gravel and fell down, the amputation and reattachment surgery was complete!.

This medicine didn't only repair the human body, many people's weapons and equipment were deformed, the soldiers smeared this glowing grit on the surface of the bent weapons, and equipment such as muskets and plate armor were restored to their original state. Even the mechanical soldiers that had been damaged by boulders were repaired by this sand.

Renyu followed the others' lead and twisted open the bottle and sprinkled a little in the palm of his hand and smeared it on his temples. The glowing grit quickly transformed into ordinary white sand and fell, a cool, soothing sensation running down his head clearing up the slight concussion that had been left behind by the boulder hitting his head across the light membrane.

"Discovered microscopic carrier energy that can be used to repair the protective light screen.” The mechanical voice suddenly rang in Renyu's mind, Renyu was first dumbfounded, looking at the fine sand emitting light in the glass bottle thoughtfully. When the protective light screen in his mind slowly fills up, Renyu realizes that the people around him are staring at the healing medicine in his hand, and the corner of his mouth twitches. He handed the vial of medicine to the seriously injured soldier next to him

Half an hour later, most of the soldiers who had not died and had survived were back in action. The battle began.

When a large group of Vinucci's searching soldiers approaches, Giacomo, the protagonist of the plot, starts the fight with the motto “Avenge Petruzzo”!.

Platoon gun against shooting began, which is a pity that in this spectacular scene, Renyu and their gang of travelers are actually the bitter first line of cannon fodder, the firing powder of the musket in this world is not the black powder of the earth. Instead, it is a natural ore refined powder. This kind of ore is this world's big name Timonium ore, the core ore that maintains this world's various energy sources, and this kind of ore will explode violently as long as a few catalysts are added to it.

The breech of this front-loading gun is a catalyst; by stuffing the powder and projectile, and then the breech mechanism is gently tipped, the catalyst and powder come into contact to create a violent explosion that ejects the projectile. Since air resistance is much greater than Earth's, the firing range of this front-loading smoothbore gun is under fifty meters.

Bullets danced on the battlefield, like a scythe of the god of death randomly picking a lucky person to harvest.Renyu's hands and feet were shaking, the light film protection of the protective light screen had been adjusted to the face and neck. At that moment, three bullets had already hit him, two of which hit the plate armor in front of his chest, Renyu's chest was like being hit by a sledgehammer. The plate armor was struck with two inward one notches. As for the third one, it flew through the slant of his helmet, and Renyu's head was violently tilted to the side under the powerful impact. At the moment of skewing, Renyu saw that the bullet flew into the neck of a soldier next to him, rounding out a fist-sized bloody hole. Frightened, Renyu used his protective light screen to protect the side above his neck as well!.

Two armies with their heads held high, facing each other with musket fire, was considered a romance. Now, Renyu looked at the increasingly thick gunpowder smoke in front of him, his heart pounding as he watched the muzzles of the opposite side firing in unison over and over again. He was playing Russian roulette with his life and death.

“Advance twenty meters towards the enemy.” General Kalini's mellow voice rang out.The Mina Legion had four times the strength of the Vinucci army, and in General Kalini's opinion it was time to press forward and collapse his opponent with a volley of flak.

But to Renyu and the other travelers, this was advancing twenty meters under enemy fire. This commander was directing them to their deaths.Renyu's steps slowed down a bit when a gunshot suddenly rang out from the rear.

The huge barrel of the gun General Kalini was holding emitted white smoke, and a black traveler looked incredulously at the large hole that split open in his chest. The protection of the protective light screen had not worked, he was trying to turn his head to escape and was killed instantly by General Kalini.

Feeling Kalini's muzzle deflected towards himself, Renyu hurriedly jogged to keep up with the group in front of him. It is said in the novels that strict military law gives farmers a fighting chance, and Renyu is now certain that it's true.
