At that time, not to mention the people of Nagasaki sounded very mysterious, even the servant army who witnessed this historical moment under Matsuura Castle could hardly believe what was in front of them.

In fact, this is not a secret in the eyes of later generations.

Gunpowder, the four major inventions of the Chinese people, was really widely used in wars in the late Northern Song Dynasty and the Southern Song Dynasty. The Mongols relied on gunpowder and Huihui artillery to conquer countless fortified cities in West Asia and Europe.

Originally, Cai Dao didn't want to be so troublesome, he had another secret weapon in his hand, that is, the failed work of the old man Lu in the blacksmith shop - a large flintlock pistol. After Cai Dao's suggestion, several craftsmen in the blacksmith shop transformed it into something that was almost a cannon, and these originally failed works finally had a second spring. During the test in Hyoji-ri, the boulder that was hit was blown to pieces.

Later, after arriving in the Wa Kingdom, after a series of things, Cai Dao figured out that he could not suppress the Wa people by virtue alone. Only by making them truly afraid of themselves can the 'Kyushu Raiders' formulated by themselves be completed quickly.

Because there is not much time left for him, on the one hand, Cai Dao has to rush back to Bianliang before and after the autumn harvest, and on the other hand, there is still a major event that has not been done when he returns to his hometown this time. Therefore, it is necessary to solve Matsuura Castle in a more shocking way.

And the sudden upgrade of the Taoist priest level also gave Cai Dao a chance to play.

The fourth-level Fire Dwelling Daoist means that Cai Dao can master the four primary Five Elements Dao Technique, and he chose the fire and earth systems before, but now he can choose the gold and wood systems. Wood helps the body grow and heals injuries. And the gold system can let Cai Dao perform the lightning technique.

Therefore, Cai Dao ordered Takagi to lead a large army to camp in front of the city gate, and then when the men and horses were in confusion, he ordered Tiezhu to lead his men to secretly dig a tunnel leading to the city gate behind the camp. On the other hand, Cai Dao is also waiting for the wind and rain to come.

Of course, the lightning spell can be performed on a sunny day or at night, but the effect of performing it on a stormy night is more shocking, and besides, he chooses a rainy night with another meaning.

According to Takagi Shinyuemon, Kentaro Matsuura does not have the courage and bravery of Arima, nor is he as sinister and cunning as Shinnosuke Omura, and he is not as decisive as the head of the Ukyu family, the weakest force. He was able to become the leader of the Matsuura Party only because his father laid a huge foundation for him, and he had a territory as large as Matsuura Castle on land. Naturally, it can deter the ambitions of those two families.

However, he has a character that does not know whether to say that it is an advantage or a disadvantage, that is, he is very admitted. If Cai Dao is really able to break through Matsuura Castle, Kentaro Matsuura will really set himself on fire. He burned himself to death, but it didn't matter, even if he dragged the Matsuura family to bury him together, no one would shed a tear for him. However, if this guy lacks the treasury of Matsuura City, what should his army eat?

Gold, silver and copper coins, even after being burned by fire, can collect the wreckage, go back to smelt it, and continue to use it; Pearls and treasures are all things outside the body, in addition to being able to give them to the emperor, what if there is one, the key to the matter now is food. In addition to collecting the wealth of the Songpu Party pirate group, Cai Dao's purpose in making a big move was to obtain the food they had hoarded in large quantities.

You must know that this is the time of April, even in the Wa Kingdom, when the fields are green and yellow, and the people are about to lose their lives. After the city is broken, if all the grain is burned, even if Cai Dao sends people to the countryside to forcibly requisition food, I am afraid that he will not be able to gather the military rations for the next operation. Because except for a large landlord like the Songura family, all the others in Songpu County were tenant farmers of their family.

When he left Nagasaki, Cai Dao also specially brought Takagi's men and the captured old pirates to the ship, and after arriving in Matsuura County, he asked these old pirates one by one if it would rain in Matsuura County these days. Of course, they all guess the weather in different ways. However, several experienced pirates still gave Cai Dao's affirmative answer, and within three days, it must rain.

This is also the reason why Cai Dao has been waiting for three days.

The tunnels were dug and the gunpowder was buried under the city gates. Because Songpu Castle was too strong, Cai Dao had his men bury about one-tenth of the total amount of gunpowder he carried under Songpu Castle.

Everything is ready, only the heavy rain is owed.

On the night of the third day, when Cai Dao was worried, the whole of Songpu County was covered in heavy rain.

There was no wind inside and outside Matsuura Castle, but there was rain, but it was heavy rain. This kind of weather is exactly what Cai Dao wants.

The moon was obscured by dark clouds, and without the blazing torches, there would be no light on the walls at all.

Since the rain, Cai Dao went to bathe and change clothes, changed into a Taoist robe, carried a peach wood sword and a treasure bag woven by Mulan Creek himself, and the iron pillar carried an umbrella for him, and the two of them drove to the gate of Songpu City step by step.

After standing still, Cai Dao didn't speak to anyone, and pulled out the peachwood sword and the talisman for casting spells from behind his back. He first made a set of standard spell casting actions, which he learned from a wandering Taoist priest in Bianliang City who cheated on eating and drinking.

Then he read it in a hearty voice: "Heavenly Spirit, Earth Spirit, Taishang Laojun is as anxious as a law, I would like to ask Lei Zhenzi Zhenjun to manifest his spirit and give me divine thunder." ”

The peachwood sword pointed to the sky, and the blood-stained captives were thrown into the air.

With a stabbing sound, a small lightning bolt flashed in the eyes of the people around him, and even on the city wall, some of the remnants of the Songpu Party who were guarding the city saw the whole process of Cai Dao's spell casting and the divine thunder just now.

Cai Dao in the rain retreated from the greenness of his baby face, which made the surrounding dart masters, sailors, and those Japanese servants suddenly feel awe.

I don't say if these people are pretending to be ghosts, but the lightning bolt is genuine. In the Wa Kingdom, even pirates who kill people without blinking an eye believe in gods and Buddhas, and the people of the Song Kingdom suddenly come out in front of the city gate, and everyone will be afraid. The hearts of the garrison in the city were filled with fear.

Fortunately, after the divine thunder flashed, it did not immediately bring out any effect.

In fact, Cai Dao has no choice.

In this era, one did not have a fuse, and the other did not have a remote control device, and wanted to ignite gunpowder in the distance.

There is only one way, and it's a stupid way.

It is to use cotton thread soaked in lard to pull it from the place where the gunpowder is buried under the city gate all the way down the tunnel to the exit, and a layer of gunpowder powder is sprinkled on the cotton thread to prevent rainwater from penetrating the tunnel and soaking the cotton thread. If there is really serious water in any of the tunnels, you have to send someone to the depths to light a fire. Moreover, when gunpowder and cotton thread burn, it also takes a certain amount of time to ignite the gunpowder packs under the city gates.

Fortunately, Tie Zhu's brain is not bright, but he is a dead brain, he did it completely according to Cai Dao's instructions, and the entire tunnel was dug very deep, nearly one meter deep underground.

The heavy rain had just begun, and it couldn't penetrate the tunnel for a while.

As the minutes passed, the atmosphere gradually became awkward.

But Cai Dao behaved calmly and calmly, lighting the line of fire until he lit the gunpowder bag under the city gate, he did not calculate how much time it would take, nor did he test it. However, he knew that once the city gates were blown open, the embarrassment would disappear.

After about five minutes, there was a loud rumbling sound under the city gate, and the huge shock wave generated by the explosion of gunpowder, wrapped in rain and mud, rushed directly into the camp.

Of course, Cai Dao was prepared, he hugged the pillar-like thighs of an iron pillar, and his small face was facing the opposite direction of the city gate, opening his small mouth and holding his ears.

With the sound of thunder, the city gate and the city walls that had been standing before were blown away.
