In the secret room under the Hundred Grass Hall.

Fang Handle was reporting to Luo Shiyin the important information that the Jinyi Guards in the city had just obtained.

"Your Excellency, according to reliable information, the Japanese army in the city has just purchased about 100,000 stone of rice from a famous pirate leader in the Yellow and Bohai Seas. The pirate ship carrying grain will arrive at the port of Incheon tomorrow.

"The Japanese army would use a large number of ox carts that had been temporarily requisitioned to transport rice to Yeongdeungpo via Bucheon. Then, the 100,000 quintals of rice were loaded onto a large warship temporarily requisitioned in advance from the Nine Ghosts Jialong of the Japanese Navy, and traveled north along the Han River to the Longshan granary north of Wangjing. ”

Luo Shiyin listened carefully to the report of the square handle, and patted his thigh happily: "You can really come whatever you want!" ”

Shi Lang, Ye Ruliu, Xie Yuan, and Shi Tianji, who were standing around, saw the excitement of the commander, and had a premonition that there would be an important action coming.

In order to fulfill the entrustment of the Holy Lord in the letter, Luo Shiyin has been looking for an opportunity for many days, looking for an opportunity to inflict heavy damage on the Japanese army, so as to delay the pace of its march and buy time for the Ming reinforcements as much as possible.

A few days ago, Luo Shiyin originally planned to burn down the Yongsan granary of the Japanese army, but he learned from the information he learned from Fang Shan that due to the attack and blockade of the Korean naval division Yi Sunsin on the southeast coast, the ships transporting supplies and grain to Korea in the territory of the Japanese were often sunk by the Korean sailors in the middle of the way, and it was difficult for them to reach the Korean coast smoothly.

Due to the inability to get timely supplies, the grain stored in the Longshan granary has been exhausted. The entire Longshan granary is almost an empty warehouse, and the Longshan warehouse is heavily guarded by the Japanese army, which is easy to defend and difficult to attack. Luo Shiyin didn't have the idea of fighting Longshancang again.

The information that Fang Handle brought to Luo Shiyin today shocked his spirits.

"How long does it take to transport rice from Incheon to Yongsan Granary?" Luo Shiyin asked the square handle.

"It will take three days and three nights at the earliest." Square Handle replied.

"What is the terrain along the Han River?" Luo Shiyin asked.

"The water surface of the section from Yongdeungpu along the river north to the south of Wangjing City is relatively wide, the terrain on both sides of the river is flat, and the field of vision is broad. From the south of Wangjing City to the north of the city, the Longshancang section of the river, the river gradually becomes narrower, and the grass and trees on both sides of the bank are thick, and the terrain is complex. In particular, on both sides of the Han River in the area of Quyan Cave in the northeast of Wangjing City, strange rocks are craggy and reeds are dense. Fang Handle replied.

"How many boats does it take for the Japanese army to transport these 100,000 stone of rice?" Luo Shiyin asked.

"This time, the Japanese army in the city temporarily requisitioned the main warship of the Nine Ghosts Jialong Naval Army, the Anzhai Boat, this ship is huge, and it requires twenty people on the left and right to row the oars, if they remove the iron cannons and ammunition on the ship, only twenty Anzhai boats are enough to hold the 100,000 stone rice." Square Handle said.

"Okay, this time, let's start with the 100,000 stone rice of this Japanese army, and we must not let this batch of rice be transported safely to Longshan Cang." Luo Shiyin said excitedly.

"My lord, how do we start?" Shi Lang asked.

"This time, let's let our underwater dragon king cannon show its might. Handle, do you have enough ammo in stockpile? Luo Shiyin asked.

"Don't worry, sir, it's enough. Despite the sheer size of this Ataku ship, it is all made of wood, and it only takes one of our underwater Dragon King Cannons to blow an Ataku ship to pieces. At that time, I will ensure that all the grain on their ship will sink into the river and feed the king! Fang said confidently.

"Okay, Shi Tianji, you are responsible for modifying the stored underwater dragon king cannon with Fang Handle in the past two days, so that it can be used during action." Luo Shiyin ordered.

"Subordinates obey!" Shi Tianji promised.

"Fang Shan, you choose the one with better water quality from the Jinyi guards in the city to follow your action, and you are responsible for blowing up the grain ship of the Japanese army, the location of the action is chosen by you, and the specific plan is formulated by you, and after reporting to me for approval, you will command and implement it. At that time, I will lead Shi Lang and them in the city, and take the sound of the explosion of your ship as a signal to blow up the ammunition depot of the Japanese army in the city. Luo Shiyin ordered.

"Don't worry, my lord, my subordinates will definitely complete the task successfully!" Square handle full of confidence.

"Once we succeed, the Japanese army in the city will be in chaos, and we will take the opportunity to leave the city. After you complete the task, just evacuate and hide, preserve your strength, and wait patiently for the arrival of my Ming Xiongshi. Luo Shiyin said to the handle.

"Your Excellency, what ...... are you?" asked Fang Shank.

"On this trip to Wang Jing, the task has been completed. It is not convenient to stay here for a long time. Luo Shiyin said.

"I'm afraid that when the humble post arrives, I won't be able to personally send the adults away." Fang Handle said respectfully.

"You just have to do what you're responsible for."

"Yes. My lord. ”

"Go ahead and get ready. When the time comes, just let the sound of the explosions of the enemy ships see me off. Luo Shiyin looked at the square handle and said.

"Yes, sir. The subordinates will prepare now. ”

"Go ahead."

Three days later. Evening.

The northeast of Wangjing City is in the Quyan Cave area.

After waiting patiently, the 20 Japanese sailors with a load of 100,000 koku of rice finally appeared in the field of vision of Fang Shan and the others.

The water surface near Quyan Cave is a corner of the Han River flowing from the southeast to the southwest, where the river is narrow, the water flow is turbulent, the strange rocks on both sides of the river are craggy, and the reeds are thick.

The reason why Fang Shank chose this place as an ambush point is mainly due to the following three considerations:

First, and most importantly, after preliminary reconnaissance and accurate calculations, according to the speed and regularity of the 20 ships of the Japanese army, it was night when they passed near the Quyan Cave, which was convenient for their movements;

Second, because the water surface here is corner-shaped, and the water is turbulent and complex, when the Japanese warships pass by, the personnel on board will definitely concentrate all their energy to deal with the dangers brought by the water.

Third, in order to ensure that the 100,000 stone of rice arrived at its destination safely, the Japanese army had already arranged soldiers to guard the shore from Yongdeungpo to Yongshanchang, and relatively speaking, the vicinity of Quyan Cave was relatively close to Wangjing City, and there were fewer Japanese soldiers guarding both sides of the Han River than in the downstream area;

Fourth, the complex terrain near the Quyan Cave is conducive to the lurking of Jinyiwei.

A day ago, Fang Shant led more than 20 Jinyi guards with good water quality, carrying more than 20 underwater dragon king cannons that had been carefully modified by him and Shi Tianji, skillfully avoiding the Japanese army guarding the coast, and lurking in the reeds on the bank of the Han River at Quyan Cave. The Japanese warships departed from Yeongdeungpoichi, and the scouts sent by Fang Handle immediately sent back the exact number of Japanese warships.

Gradually, you can see that the windproof fog lamps on the bow of the Japanese army are swaying in the cold night breeze on the river, emitting a dim light.

Twenty huge Ataka boats, each spaced a certain distance apart, were connected to each other, and slowly sailed on the river. The entire fleet swam like a long dragon lying on the water, towards the spot where they were ambushed.

"Check the ammunition and equipment, and prepare for action!" Square Handle commanded in a low voice.

"Checked." The subordinate whispered in response.

"There is a dangerous shoal ahead, all pay attention, go all out!"

Hiding in the reeds, Fang Shante and the others could clearly hear the shouts of the commander of the Japanese Navy on the ship.

Hearing the order, the sailors in charge of rowing on the ship immediately shouted a uniform trumpet and rowed hard.

Twenty Japanese ships moved slowly through the rapids.

"Action!" Seeing that the first Ataku boat had turned the river in front of him, Fang Shanshan immediately ordered.

Fang Handle and nineteen brocade guards immediately held the underwater dragon king cannon in their hands, and took advantage of the night to swim towards the enemy ships on the river. The remaining brocade guards lurked in the reeds, ready to pick up the personnel involved in the bombing operation.

Just when Fang Shan's subordinates were waiting for the arrival of the Japanese ships on the Han River northeast of Wangjingcheng, Luo Shiyin led Shi Lang, Ye Ruliu, Shi Tianji, Xie Yuan and Li Ruzhu to sneak near Changdeok Palace.

Changdeokgung Palace is one of the five palaces of Wangjing, it is like other palaces of the Joseon royal family at that time, the architectural style completely adopts the architectural characteristics of imitation Ming, and it is completely designed in accordance with the natural terrain, and it is the most natural palace in the Korean palace.

Although Changdeokgung Palace also sits in the north and faces south, its palace is not distributed according to the north-south axis like Gyeongbokgung Palace, the main hall of Injeongjeon, the palace of Seonjeongjeongjeong, the dormitory of Heejeongjeongjeongjeong, the middle hall of the Dazao Hall, etc., are arranged in order from southwest to northeast according to the topography, so that the whole Changdeokgung Palace and the surrounding natural features are organically combined, and play a magical effect that complements each other.

From a distance, the entire building of Changdeokgung Palace shows an elegant and noble style.

Changdeokgung Palace was once the residence of members of the Joseon royal family and court ladies. After the Japanese occupied Wangjing, they used this place as a place for the Japanese army to store ammunition and guns. Almost all the gunpowder and lead pellets used by the Japanese iron artillery were stored here.

In order to successfully complete the sabotage mission, Luo Shiyin had ordered Shi Lang and Ye Ruliu to secretly infiltrate Changdeok Palace twice before the operation, and conducted a detailed survey of the architectural layout in the palace and the storage of ammunition for the Japanese army.

Through the platoon, it was found that all the gunpowder and lead shots used by the Japanese army's iron artillery team were piled up in the Xuanzheng Hall of the Changdeok Palace, and they were guarded by the Japanese army sentries all day, so it can be said that they were heavily guarded and difficult to enter easily.

From the information provided by Fang Shan, it is known that whenever there is a major military operation, the Japanese army iron artillery team will come here collectively to collect iron cannon lead pellets.

At this time, Luo Shiyin, Shi Lang and other six people were sitting at an inconspicuous wine table in a wine shop on the right outside the main entrance of Changdeok Palace. They were patiently waiting for the actions of Fang Handle and others outside the city.

"Ladies and gentlemen, the dishes are cold, why don't you heat them up?" The shopkeeper looked at Luo Shiyin, Shi Lang and other six people wearing the costumes of the Japanese warriors, and diligently added tea and water.

"No need, go ahead of your business." Xie Yuan replied in Japanese and waved at the shopkeeper.

"Good come!" Although Xiao Er, who was born locally, couldn't understand Xie Yuan's words, from Xie Yuan's expression and gestures, he immediately guessed what Xie Yuan meant, and hurriedly went to greet other guests.

The costumes worn by Luo Shiyin, Shi Lang and other six people are the costumes of the six Japanese warriors captured at Yingshuyi when they first entered the city. With the help of Xie Yuan, Ye Ruliu disguised herself as a man, and she could barely see her daughter.
