The roar of the earth-shattering iron cannons came and went, leaving various marks on the castle walls, window holes, and wooden gates of Tsuruga Castle like a ghost.

Asakura Jingxing, who were arranged behind the arrow turret and the board screen, and were about to fire feather arrows at Wang Tian's evil army array, were shot in the head by lead pellets and fell to the ground. The gate of the Sannomaru Grand Entrance was also bombarded by iron cannons, and it became full of holes.

The so-called board screen is made of bamboo as the skeleton filled with red clay, and the exterior is whitewashed, with arrow holes for archery in the middle. It's just that at this moment, these fortifications, which originally looked very strong on the outside, all roared under the bombardment of Wang Tianxie's iron cannon.

The red clay painted white was ruthlessly peeled off by the iron cannon, and the bamboo inside was also ruthlessly penetrated.

As for the archers hiding behind, they were directly shot into a sieve by the lead pellets fired by the 2,000 iron cannons through the "four-stage shooting".

"Huh? Odd! Wang Tianxie, who was standing in the main tent of the main camp of the formation, suddenly turned his head to look at a towering ancient forest in the distance behind him.

"Master, what's wrong?" The half-guard of Takenaka followed Wang Tianxie's gaze and asked curiously.

"It's nothing, maybe it's an illusion." Wang Tianxie shook his head, a hint of puzzlement on his face.

Ever since he gave the order for the iron cannon to shoot in four sections, he had a vague feeling of being watched. It's just that, perhaps because of the distance, Wang Tianxie didn't find the other party's figure.

In this turbulent era of the Warring States in the 16th century, the firing range of the iron cannon is only 250 meters at most, which is about the same as the firing distance of a bow and arrow. Moreover, it is only possible to reach this distance under the premise of reducing the accuracy.

It's just that as early as the violent overage pseudo-Lori succeeded as the head of the Oda family, unifying and completely controlling the Oda family. Tariffs within the Oda family's sphere of influence were abolished, thus attracting elites from all walks of life.

At that time, Wang Tianxi, together with a large group of craftsmen skilled in smelting, invented a crosshair for the Oda family's iron cannon, which greatly improved the accuracy of shooting within 250 meters.

Subsequently, he invented a variety of auxiliary tools and convenient methods to improve the loading speed and power of iron cannons. As well as practicality on rainy days.

And two years ago, when Li Huamei, the big cat sister of the iceberg, came to Oda's house to play, she brought a gift to Wang Tianxie, which immediately inspired him again.

Iceberg Big Cat Royal Sister Li Huamei brought a long-handled iron cannon to Wang Tianxie. However, this iron cannon is not an ordinary iron cannon, but an iron cannon with a "rifling" carved inside the barrel.

According to the Iceberg Big Cat Royal Sister, as early as the fifteenth century, the Western countries on the other side of the Great Voyage had already invented iron cannons with rifling. The problem is that although the range and accuracy of this iron cannon have been greatly improved, it has a fatal flaw.

The so-called "rifling" is a series of swirling engravings carved in the barrel of the gun. The lead pellet can be shot in a rotating barrel, which not only increases the range, but also greatly improves the accuracy of horizontal shooting.

"Heavenly evil, according to those craftsmen, the concave part of the barrel is called the yin line, and the raised part is called the yang line. However, this kind of gun is more convenient when hunting, but when fighting. It's just chicken ribs. However, I look at this thing as a novelty. I got you an eye-opener. ”

This is the original words of the iceberg big cat royal sister, Wang Tianxie didn't understand the meaning of this iceberg big cat royal sister at first, until he really tried to shoot it, and then he came to his senses.

Wang Tianxie, who has been playing with ordinary iron cannons for so many years, if he still doesn't understand the meaning of the words of the iceberg big cat royal sister, he can directly find a piece of tofu and kill him.

Don't look at this iron cannon with rifling. Even with a staggering range of more than 500 meters, the accuracy remained at a very high level. But the problem is that this firing rate is definitely one-third, or even one-quarter, of the iron cannon I usually play.

Even if Wang Tianxie used the Oda family's current "four-stage shooting", I am afraid that the frequency of a salvo is about the same as that of an ordinary military formation.

No wonder the iceberg big cat sister said that it is only suitable for hunting. Not suitable for use on the battlefield.

Wang Tianxie was full of ultimate envy and jealousy for the range of 500 meters.

In this troubled world where the range of bows and arrows has reached 200 meters, almost the same as the range of iron cannons, it is absolutely a terrifying thing to have a powerful firearm with a range of 500 meters.

Not to mention five hundred meters, even if it is only four hundred meters, Wang Tianxie will already be like a fox who has stolen a big hen, shaking his head and waging his tail happily.

The problem is that since the lead shot must be embedded in the rifling in order to rotate with the rifling, the diameter of the projectile must be greater than the diameter of the male wire of the rifling.

As a result, in order to load the lead pellet into the barrel, Wang Tian had to use a small hammer to continuously beat the bullet stick, and it took a lot of effort to finally load the lead pellet into the barrel.

Fortunately, the Ming Kingdom on the other side of the sea has a saying called "If you are poor, you will change, and if you change, you will be successful", which is indeed very reasonable.

It took Wang Tianxie nearly a year to finally come up with a solution. With the help of those craftsmen, he changed the originally round lead pellet into a cylindrical shell lead pellet that resembled the "wowotou" of the previous life.

The new lead shot is somewhat similar to the pistol bullet of the previous life, but the cylindrical bullet is much shorter and recessed inward.

The diameter of this new type of lead shot is one turn smaller than the diameter of the male wire of the barrel, just enough to be easily filled into the barrel. In one fell swoop, it solves the embarrassing situation that the lead shot cannot be plugged into the barrel or blocked due to the large size of the lead shot.

Since the newly invented lead shot could easily be pushed into the chamber with a ram lever, the rate of fire was naturally greatly increased.

The reason why the diameter of the lead shot must be greater than the diameter of the male wire of the rifling is to keep the chamber completely sealed after being embedded in the rifling and rotating with the rifling, so that the gunpowder slag will not remain and block the barrel and cause explosion.

That's why Wang Tianxie changed the shape of the lead shot and curved the tail and concave inward.

The new lead shot is surrounded by a cylindrical projectile with threads that swirl like rifling, and the middle of the thread is stuffed with animal oil, and the recessed part of the tail is filled with cork.

As a result, when the cannon is fired, the gunpowder gas instantly hits the cork, causing the cork to suddenly expand the tail of the lead pellet in an instant.

The tail of the lead shot is stretched out, and the sealing of the chamber can be completed by relying on the thread of the lead shot itself at the moment of launch, so that the kinetic energy of the new lead shot will not be lost due to the leakage of gunpowder gas.

As a result, the problem of chamber closure was solved in this way, which significantly increased the rate of fire, range and safety of rifled iron guns.

In addition to these advantages, Wang Tianxie made a big profit.

Due to the existence of this rifled iron cannon called "chicken ribs" in the Western countries on the other side of the Great Voyage, even if its manufacturing complexity is higher than that of ordinary iron cannons, its purchase cost is many times lower.

This is also the reason why the Oda family was able to pull out 4,000 iron cannons today in 1557. After all, weapons that can only be used for hunting are far less valuable than weapons that can be popularized in the army.

Wang Tianxie arranged the iron artillery team of the Oda Ghost Army, which was lined up in the shape of a figure of eight, at a position of 350 meters.

"How can it be repaired! Yaga! Yaga! Yaga! Yaga! You're all pigs! Stupid pig! This distance was so angry that he scolded Cang Jingxing and stomped his feet.

For Asakura Keiyuki's military formation, the distance of three hundred and fifty meters was just out of range of the Asakura family's archers and the only dozens of iron cannons.

But for the Oda family, the distance of three hundred and fifty meters is definitely the range where the rifled iron cannon can exert its greatest power. The lead shot that spun out even pierced the iron gate of the Sannomaru Grand Entrance, knocking the guard behind the iron gate to the ground.

Not to mention the arrows and screens that were originally made of bamboo and wood, but they were shot by the Oda Ghost Army Iron Artillery Team and peeled off the red soil, and the bamboo boards were densely covered with holes.

"Half-guards! Out after a volley! You go and get that Asakura Yoshikei back for me! "Wang Tianxi's full "four-stage volley" lasted for an hour, and finally with a wave of his hand, he ordered the second-echelon cavalry team of the Takenaka half-guard to go out and charge towards Tsuruga Castle.

It's no wonder that Asakura Jingxing is so depressed that he scolds.

At this time, the Tsuruga Castle Sannomaru had become full of holes, and the garrison formation, which had only more than 2,000 people, not only did not kill a single enemy in this hour, but also killed more than 500 people by the iron artillery team of the Oda Oni Army.

This is still because he saw that the momentum was not right, and ordered the garrison to lie on the ground and crawl back to Ninomaru to survive.

The "four-stage salvo" of the Oda Ghost Army's iron artillery team finally stopped, and the dense roar of the iron cannon finally stopped, leaving only the white gunpowder smoke flying in the sky, and the most pungent smell of gunpowder.

"Huh......" Asakura Jingxing suddenly breathed a sigh of relief in his heart, but then his face changed greatly.

The tremor from the ground instantly told him that it was a horse team galloping.

The horse team that appeared at this time, whether it was the enemy or the reinforcements, naturally did not even need to think about it, and did not need to look at it to determine it.

"Whole army! Resist! The Oda family horseback team has attacked! Ladies and gentlemen! Fight back desperately! Asakura Keiyuki pulled out the big sword at his waist and shouted at his men.

The ashigaru team of more than 1,000 people faced the 6,000 cavalry team, and the result was tragic.

Takenaka Hanbei, the best pseudo-girl who has followed Wang Tianxie since he was six years old, entered no man's land, and the big sword in his hand slashed left and right, rushing towards Honmaru.

Those Ashigaru with a dead will were not his enemies at all, and they were all cut in half by his big sword under the dash of the war horse.

As for the Asakura family, who was not on his path, he didn't even look at it. The goal given to him by Wang Tianxie is very clear, that is, the righteous fox of Asakura Yoshijing.

Well, after all, Wang Tianxie didn't know that the sick fox had secretly escaped from the secret passage in the early hours of this morning. (To be continued......)
