Quyan Cave near the middle of the Han River.

The square handle paddled his arm vigorously and allowed his body to move quickly on the water.

In the darkness of the night, the first Japanese ship was already in sight, and the Japanese sailors on board were engrossed in shouting trumpets and paddling vigorously to make the boat smooth in the rushing river.

Fang Shank observed the situation on the boat, and saw that no one was paying attention to the movement of the river under the boat, so he paddled hard to the stern of the boat in front of him, grabbed a bulge on the hull with his left hand, and pressed the underwater dragon king cannon in his hand on the stern side of the boat with his right hand.

This "underwater dragon cannon" is actually an ancient mine, which is the earliest floating mine in the world, and can be said to be the originator of modern drifting mine. Its structure is to use cow urine bubble (i.e., cow's bladder) as a thunder shell, filled with black gunpowder, and use incense as a fuse to play the role of delayed detonation.

The cow's urine bubble is attached to the floating wooden board and under the goose wings, and the goose wing tube and sheep intestines are used to ventilate the incense, so that even if the wooden plank fluctuates up and down with the waves, the water cannot be poured in, ensuring that the incense can burn normally.

The fuse of this underwater weapon is based on the distance to the enemy ship and the speed of the water flow to determine the length of the incense, and then predetermined the time of the explosion, it uses the water flow as a driving force, when approaching the bottom of the ship, "incense to the fire, the cannon from the bottom of the water", unexpectedly bombarded the enemy ship from the water.

Prior to this operation, Fang Shan and Shi Tianji had also envisioned using the impetus of the current to make drifting mines, and placed them upstream of the Japanese ships in advance. However, considering that the Japanese ships sailed in a "one" shape this time, if only the effect of the water flow, the underwater dragon king cannon placed in the Han River may only blow up the ships sailing in front, and the ships behind will most likely not be able to blow up.

Based on this, Shi Tianji and Fang Handle simply improved the underwater Dragon King Cannon, smeared a layer of highly viscous fish glue on its surface, and when acting, the Jinyi Guard carried it close to the enemy ship and forcibly stuck it to the enemy ship, so as to effectively avoid the blindness of the explosion in the floating situation and improve the accuracy of the attack.

Seeing that the underwater dragon king cannon in his hand was firmly glued to the enemy ship, Fang Shank took out the fire sickle and turned his body back to the ship behind, so that the enemy on the enemy ship behind would not discover the fire light from the fire sickle in his hand.

After lighting the incense attached to the gunpowder, the square handle carefully looked at the side, and after making sure that everything was safe, he immediately sank to the bottom of the water and dived towards the reeds on the shore.

At the same time, the other brocade guards who acted with Fang Shan's side also did the same, and the underwater dragon king cannon in their hands was firmly glued to the Japanese army's houseboat, and after lighting the fuse, they swam towards the reeds on the shore.

Yan Bahe was responsible for the installation of the underwater dragon king cannon of the last Ataku ship, and just as he was about to swim to the shore after laying the mines, he was discovered by a Japanese sailor on the ship, who immediately shouted loudly: "There are people in the water, there are assassins!" ”

Hearing the shout, more than a dozen soldiers of the Japanese Navy on the boat raised their bird guns in their hands and shot at the swallow crane in the water.

As hard as he could, he dived into the water and swam into the distance, when he was about to approach the reeds on the shore when he suddenly felt a sharp pain in his back, and a lead pellet from the Japanese army hit him in the back of the heart and came out of his chest. Blood poured out of his body. The swallow crane surfaced in intense pain and swam into the reeds, blood staining the water behind him.

"Bahe, hold on." Fang Shan, who had already arrived first, and the others helped the swallow crane to the shore.

"Boom, boom, boom ......" With a series of loud noises, the water surface of the Han River in the night suddenly burst into flames, and the grain ships of the Japanese army in the river exploded and caught fire one after another, and the Japanese soldiers who were not killed on board cried and jumped into the river one after another.

In less than a quarter of an hour, all the grain ships on the river sank to the bottom of the river.

At this time, the soldiers of the Wa Kingdom who were in charge of guarding on the shore found Fang Shan and the others who had just landed on the shore, and they shouted one after another, waved the weapons in their hands, and killed this side.

Fang Handle and the others had to swing their knives to face the battle.

"Take care, sir!" Yan Bahe, who was already dying, saw that he had no hope of escaping, and struggled to cherish the other handle, and then suddenly pulled out the embroidered spring knife on his body and killed himself.

"Ba He, my good brother!" Fang Handle screamed in pain, helplessly glanced at Yan Bahe, who had fallen to the ground and had died of anger, and slashed to death a Japanese warrior who had killed in front of him.

The Japanese soldiers gathered more and more.

Seeing a large number of Japanese soldiers running towards him, Fang Handle immediately shouted an order to the Jinyi guards who did not participate in the bombing of the ship: "Shorten the fuse of the underwater dragon king cannon in your hands, then light it, and throw it at the enemy when it is about to explode." ”

"Yes, sir." Several brocade guards who received the order immediately followed the instructions of the square handle, broke the fuse of the underwater dragon king cannon in their hands and lit it, and then threw it at the surrounding enemies.

"Boom, boom, boom......"

With the loud sound of the explosion of several underwater dragon king cannons, the Japanese soldiers who ran quickly around the Jinyi Guard were killed in large pieces.

"Brothers, go out with me! Fang Shant shouted, brandished the embroidered spring knife in his hand, and slashed towards the east where the enemy's strength was relatively weak.

Fang Handle led his men to fight hard, and after paying the price of two dead and three wounded by the accompanying Jinyi guards, he finally broke out of the encirclement and successfully hid in the mountains not far east of the Han River.

Hearing a loud explosion outside the city, Luo Shiyin and the others, who had been sitting in the wine shop outside Changdeokgung Palace, were secretly happy in their hearts - the first step of this operation seemed to have been successfully completed.

Next, it depends on whether they can take the second step in the city smoothly.

At this time, a loud horn sounded on the street outside the liquor store, and a large number of Japanese troops poured in from all directions.

"Don't panic, all line up and go inside to get weapons in order!"

Outside Changdeok Palace, a Japanese army commander wearing a wheel-pierced ribbed helmet, black iron armor, and a pale yellow array of feathers was commanding a large number of Japanese soldiers in front of him with a hoarse voice.

"Action!" Luo Shiyin commanded in a low voice.

Hearing the order, Xie Yuan quickly handed over some of the scattered silver prepared in advance to the shopkeeper, and then, the six of them quickly walked out of the door, mixed in a group of Japanese soldiers who were running towards Changdeok Palace, and ran towards the gate of Changdeok Palace.

"All under my command, run forward, follow me in and get weapons!" The commander of the Japanese army gave an order, and the Japanese soldiers who had already lined up in formation walked into the Changdeok Palace with neat steps.

"The first team of fifty men went first to receive the iron cannons in turn, and then the second team of fifty people. After receiving their weapons, all personnel assemble in the square on the right. Don't run around! The commander of the Japanese army commanded loudly.

Luo Shiyin and the other six stood among the fifty people in the third batch.

The 100 Japanese soldiers in front had already drawn their iron cannons from the Seonjeongjeongjeon Hall of Changdeokgung Palace and ran towards the square on the right.

"Keep up, hurry!" The commander of the Japanese army ordered at the team of fifty people where Luo Shiyin and the other six were located.

In the Seonjeongjeong Hall of Changdeokgung Palace, rows of Japanese iron cannons are neatly arranged against the wall.

The people who entered the hall took an iron cannon (bird gun) from the weapon rack in turn, and then turned around and walked out of the Xuanzheng Hall around a small corner.

When it was Xie Yuan's turn to take the iron cannon, according to the prior arrangement, he deliberately pretended to be careless and knocked down the entire weapon rack.

"Bastard, clumsy guy!" The Japanese soldiers behind Xie Yuan couldn't help but shout and curse.

"I'm sorry!" Xie Yuan apologized in Japanese.

"Hurry up and put up the weapon rack!" Someone shouted.

The Japanese soldiers in the shop leaned down one after another, trying to get the weapon rack back in hand.

Taking advantage of this chaos, Shi Tianji quickly flashed to the gunpowder stacking place in the northwest corner of the main hall, took out an underwater dragon king cannon prepared in advance from his arms, quickly lit a fuse made of incense, and then stuffed it into the gap under the powder keg at the bottom.

"Hurry, hurry, hurry, the next batch is coming in!" Under the mutual urging, the fifty people in the hall took their weapons one after another and walked to the square outside the hall.

"Our army's food convoy was attacked, and everyone immediately followed me out of the city to reinforce it. Let's go! The commander of the Japanese army immediately ordered when he saw that all the men had finished taking their weapons.

The streets from Changdeokgung Palace to the north gate of Wangjing City were bustling with Japanese soldiers rushing from all over the city to the outside of the city.

Seeing these Japanese people with loaded guns, the people walking at night on the streets panicked and hid on the side of the road.

Luo Shiyin, Shi Lang and others followed the running team out of the north gate, then turned right, ran along a potholed dirt and stone road for nearly a quarter of an hour, and came to a place called Hupao Ling.

There is a fork in the road halfway up the mountain. Xie Yuan saw the opportunity, and his body stumbled and fell to the ground.

"Ouch, it hurts me!" Xie Yuan squatted on the ground and shouted bitterly in Japanese.

Luo Shiyin, Shi Lang and the other five people hurriedly stopped and helped Xie Yuan up.

This process has left six people at the back of the line.

"Hurry up, keep up!" One of the Japanese leaders turned back and ordered.

"Yes!" Xie Yuan replied, reluctantly got up, and limped forward with the support of Shi Lang and Ye Ruliu.

Taking advantage of the fact that no one in front of them was paying attention, Luo Shiyin, Shi Lang and the other six people quickly turned onto another fork in the road and ran towards the mountains to the north.

"Boom, boom, boom......"

Luo Shiyin, Shi Lang and the other six had just climbed a mountain peak, and a series of explosions were heard from the direction of Changde Palace in the capital city behind them.

From a distance, the sky above Changdeokgung Palace is blazing and smoke billowing to the sky.

"Looks like the enemy's powder magazine has cost us a reimbursement!" Shi Lang said excitedly.

"Let this loud explosion see us off!" Xie Yuan opened his arms excitedly.

"With the loss of food and ammunition, the Japanese people in this city have no choice but to blow up the pot!" Shi Tianji shouted happily.

"It's called a 'double cannon'!" Ye Ruliu said happily.

"Let's go, our next move is to go all the way to the south, continue to reconnoiter the armaments of the Japanese army on the southeast coast, and rush to the Jeolla Province Navy Commander Envoy Yi Sunsin to find out the strength of the Japanese army." Luo Shiyin, who had successfully completed the two tasks, was in a happy mood, and he gave the order to the members of the team for the next move.
