Receiving this sudden attack, the troops by the river panicked to a certain extent, and their own soldiers and subordinates immediately gathered around the Shioi Kyoye and hid behind a natural bunker formed by a large rock. Shiwai Kyoye squinted his eyes and looked at the other side, carefully observing the situation here.

The river course of the Shattered Tamagawa River is not very wide, and the widest part of the river is only 70 meters, but because it flows down from the mountains, the water is still very fast! Every year, when a flash flood erupts, a large number of rocks are carried down, and the gentle riverbed here is covered with large and small pebbles for many years, and the occasional huge rock that rolls down occasionally pokes out half of its head from under the water. Due to these obstacles, the rushing water creates layers of white waves on the surface of the river, which is also the origin of the name "Broken Tamagawa".

The so-called original bridge is not too large, it is a simple wooden bridge formed by using some natural or unnatural "piers" in the river and supplemented by some wooden frames, and covered with wide planks. Such a fragile bridge has to be rebuilt every year after a flash flood, but it is nevertheless passable for vehicles! At the moment, the bridges and wooden frames were dismantled in disarray, and wisps of white smoke rose from behind some large rocks on the other side of the river.

"Is it going to flank us?" Takatsu asked uneasily.

"It doesn't look like a ...... from this location," he said, looking around, there was no woods on either side of the river that was suitable for the large army to hide, and the bare mountains and fields were clear at a glance. Besides, this place is not too far from Jianbu Mountain City, and the activities of the brigade must have been discovered a long time ago! In order to determine this idea, he carefully counted the smoke points over there, and there should be only two dozen iron cannons. "Prepare to cross the river and attack!" Although there should be a large detachment of ninja troops with so many iron cannons, it is not enough to stop the advance of thousands of troops.

"We only have three boats, loading soldiers on the target is not ......"

"Organize soldiers to wade through the water!" Shikai interrupted his subordinates' complaints. The situation in Fengshan City is critical, and he really can't afford to delay!

300 spearmen descended into the river, and were stimulated by the water. Even though it's late spring, the snowmelt water that flows down from the mountains is still cold!

Although there is no danger of sinking into the silt, the uneven gravel still makes people stumble. By the time they reached the middle of the river, the river was already waist-high, and the spear ashigaru walked even slower due to the rapid impact of the current!

"Bang, bang, bang......" The sound of iron cannons on the other side of the river seized the opportunity to sound again, and the leading dozen soldiers fell headlong into the river. Bright red blood bubbled on the surface of the water for a moment, and then drifted downstream with the corpse.

"Bow and arrow! Bow and arrow cover! Takatsu Changshi shouted loudly to the troops behind.

500 bowers gathered on the riverbank and shot the feathered arrows of Hu Zhong with their longbows to the opposite bank without hesitation. For a while, the arrows rained down, and the snapping sound of shooting on the big stone on the opposite side could be heard clearly, but the effect was not obvious!

The enemy's ninja army was very well ambushed, the boulders on the shore and the remaining bridges effectively blocked the damage of the bow and arrows, and the feathered arrows were lighter, and the high parabolic shooting method was even more useless. The sound of the opponent's iron cannon is still dense, although the number is small, but each time one or twenty people are put down, the rapid flow of water makes it difficult to speed up the speed of the attack, and after a while, only half of the 300 spears are left!

Shinoi Jiaoye was anxious and angry now, and he couldn't understand why the few iron cannons on the other side had such a huge lethality? In the past few years, in the battle with the invading Oda army, I have not found that a large number of iron artillery teams have participated in the battle, how can there be so many at once! Judging from the area of the opponent's bunker, it is impossible to hide too many people, could it be that one person carries several iron cannons and shoots in turn? But that's not right! The bullets should have run out of bullets a long time ago according to this play, and how many people would have to follow behind to reload!

Looking at the huge casualties in the river and the time that was delayed little by little, Shinoi Jiaoye gritted his teeth and was ruthless, and it seemed that the "killer feature" that was originally prepared to be reserved for the critical moment must appear in advance. "Tell all the troops to withdraw! Order the Chinese army to push out the 'big cylinder', and prepare the fire yao and projectiles! He commanded loudly.

"This ...... Be! The general wanted to say something, but he retreated under the angry gaze of the Shinoi Sect.

The spear ashigaru in the river "bone, roku, roku......" all ran back at the call of the command, and with a series of piercing rolling sounds, two behemoths covered in tarpaulins appeared on the riverbank, and dozens of soldiers behind them laboriously carried over some heavy wooden boxes and barrels. When the tamab was revealed, two cannons appeared, the barrel was filled with black fire yao, and the wooden box was filled with projectiles the size of lead balls. It's absolutely impressive, but if you look closely, you can see that the cannon's barrel is dark brown, and the projectiles are gray.

It has been more than 20 years since Europeans came to Japan, and iron cannons are quite common, although they are still expensive, and many "people of insight" have noticed the powerful firearms of cannons! However, the European maritime powers all had the "Navigation Act" to limit the export of artillery, and the road to "localization" of cannons was far less smooth than that of muskets. The casting of the cannon body is too difficult, and it will explode if it is not very good! This technique has not even been mastered by Tanegashima and the national house, let alone the hillbillies of Tamba Hatanoya!

However, the peasants also have the wisdom of the peasants, and a guy with some insight found the structural diagram of the projectile cannon in a copy of the Yuan Dynasty's "Firearms Cardinal Illustrated Book", plus the lush forests of Shanyin, which really made them successfully trial produce wooden cannons!

Take an old pine tree with a thick and thin hug, peel it vertically, dig out a smooth gun chamber from it, fix it with seven iron hoops after closing, and then install a detachable iron back cover at the tail to make a shelf with a wheel. Due to the thin structure and unable to withstand excessive pressure, it was only able to fill a small amount of fire, and it still fired stone projectiles, but the maximum range had reached 150 meters.

This kind of cannonball that can't explode when the two armies are fighting together (in the 10,000-horse army, it can only be regarded as your back!). It's almost useless, but it's a good market when attacking and defending cities! The long-range bombardment of the city gate is similar to that of the fortification, and it avoids the many casualties that may be caused by the soldiers gathering under the city; When defending a city, with the advantage of distance from the city walls, you can easily destroy the opponent's heavy equipment.

This secret weapon of the Hatano family should have been just in case, but at this moment, the Shioni Kyoye can only take care of it!

A dozen ashigaru hurriedly poured the fire into the barrel of the cannon, and then compacted the fire from the mouth with a tool similar to a long-handled cloth. A seasoned gunner adjusts the gun position as ordered, shifting angles from time to time. Anyone around instinctively took a few steps back, many of them having learned the noise of the weapon.

Just like nuclear weapons in contemporary society, the mysterious unknown itself is a deterrent, in fact, what is the difference between being able to destroy the earth once and a hundred times, the greatest deterrent power of missiles is not when they are fired but when they are on the launch pad. The current Hatano cannon is at such a time, and the people on both sides of the river are watching quietly and nervously, only the river is still flowing carefree.

After a cup of tea, the gunner signaled to Takatsu feldspar that it was okay! Takatsu Feldspar turned to Shinoi and cast an inquiring look.

"Let's get started!" Shiwai nodded slightly.

"Hiss~~~!" A piece of grass rope stained with fire was lit, and white smoke burned through the small hole where it was inserted, and everyone nearby quietly plugged their ears. There was still no movement on the other side, and I wondered if the enemy hiding there had already fainted.

"Boom! …… Bang! After two loud roars, the projectiles flew straight to the other side of the river, but most people didn't see their trajectory because of the speed. With two crackling sounds on the other side of the river, I saw stone chips flying in all directions in the thick smoke, and they made a large splash on the surface of the water like raindrops. Because this effect can only be achieved by hitting a boulder on the riverbank, it can never be seen on the ordinary battlefield!

The actual lethal effect did not work, but the achievement of deterrence was obvious! Everyone saw more than two dozen people running out of several hiding spots on the opposite bank, fleeing into the mountains in the distance, each carrying a black and shiny iron cannon behind him.

"Cross the river as soon as possible! Everyone went into the water and waded, and the ship was used to transport equipment and supplies! He shouted an order to everyone, and then walked down the river bank and into the water.

Finally crossed the Broken Jade River, but the time also changed from morning to afternoon, and this is only a combat unit, and the baggage is still continuing to struggle with the river! It was useless to look at the urge, so he left 1,000 soldiers to protect the baggage and then followed, while he led the rest of the troops to continue to hurry. Towards evening, they came to a valley. The idea of relying on the Jingjing education industry is especially scary in the starry night, but things are not as good as the sky (or people) want!

"My lord, the exit of the valley has been blocked by a big tree that has been cut down!" The heralds of the former army once again brought bad news.

"Clear the obstacles and move forward!" Not only did he lose the interest of observing for himself, but he was even tired of getting angry.

"Be careful, sir!" Kubino Jusan Lang, who was beside him, suddenly shouted and threw him to the ground. "Whoosh!" With a thud, a feathered arrow stuck in the place where he had just stood.

"The whole army is on alert, protect your lordship!" At the same time as the general of the guard shouted, many arrows were shot from the mountains and forests on both sides of the valley.

Shiwai Kyoye observed the surroundings, judging from the number of bows and arrows, the enemy would not exceed 50 this time, and the birds and beasts in the nearby mountains and forests had only flown in a few places, far from the point of large-scale running. "Send 300 men up the mountain to search for the enemy, and the others continue to advance!" He pushed away the people around him and shouted orders to the troops. “… No matter what harassment you want to encounter, you can't stop, and the second striker and the Chinese army will send a team to clear it! The backward troops moved together with the baggage, and those who fell behind retreated to the mountain castle of Jianbu on their own! He added.

As a result of desperate measures, Shiwai Kyoye finally arrived at Mineyama Castle on the afternoon of the third day with 2400 exhausted troops! To his delight, the banner of the Hatano family was still flying high in the castle......
