In this way, the causal relationship is well understood.

The manufacture of this arquebus must have had a close relationship with the Great Chief.

Subsequently, Zhou Mingyue learned from a relative of the big leader that the big leader family had a treasure, and this treasure could make arquebuses!

As for what this treasure looks like, the relative doesn't know, but he only knows one thing, that treasure can't be moved!

After learning this, Zhou Mingyue immediately transferred more arquebusiers to conduct a dragnet search of the entire Great Chief's Palace.

Soon, the entrance to an underground palace located under the Great Chief's Palace was discovered.

The passage at the entrance to the underground palace is more than 1,000 meters long.

However, the garrison was extremely strong, and a small army of thirty men with fine arquebuses was stationed in its passages.

Well, the high-quality arquebus is the arquebus used by gunpowder (division commander) and bullet (brigade commander), and so far, Zhou Mingyue has not captured one.

This small army did not leave the underground palace passage even when the Great Chief's Palace was captured by Zhou Mingyue.

Therefore, when Zhou Mingyue's arquebusiers entered the passage of the underground palace, they suffered great losses at the first time.

Whoever it is, in that passage, will not be able to withstand the bombardment of fine arquebuses.

Where is the arquebus, it is a cannon!

You know, according to the number of troops in the city of Rearthur, there will be no more than twenty-five high-quality arquebuses!

But there are 30 high-quality arquebuses in this dungeon passage!

This was simply beyond Zhou Mingyue's expectations.

In the ensuing battle of the passage, the arquebusiers lost thousands of men, and they used their lives for lives to break through the passage of the underground palace.

However, the losses were also heavy.

Well, this mainly refers to those fine arquebuses.

In the Battle of the Passage, although Zhou Mingyue's side was victorious, more than 20 of the 30 high-quality arquebuses were blown to pieces.

This is not surprising, even if the arquebus is of high quality, it is broken, and in the battle of the passage, such a violent and continuous explosion, not all of which were destroyed, is already considered luck.

However, Zhou Mingyue kept the great chieftain's secrets more than those high-quality arquebuses at this time, so after learning that the battle of the passage was over, he rushed to its entrance as soon as possible.

Compared to the splendid Grand Chief's Palace, this dungeon looks very inconspicuous.

Its entrance is actually built at the back of a toilet palace.

Well, the so-called toilet palace is the toilet in the palace of the big chief, but it is also splendidly repaired, and when Zhou Mingyue saw it for the first time, he couldn't believe that this was actually a toilet.

With an area of more than 500 square meters, a comfortable toilet for only one person, can you believe it?

Of course, fortunately, although this entrance is built behind the toilet palace, because the toilet palace is only for the big leader to go out of the palace, so it doesn't smell any smell.

Come to think of it, no matter how the big leader says it, he can be regarded as a golden branch and jade leaf, and a person with an extremely noble status can't make the place where he needs to go in and out often stink.

However, due to the previous battle, the underground palace passage at this time can be called a sea of flesh and blood.

Humanoid minced flesh, bones, and a mixture of broken arquebus parts stuck to the walls of the passage, look like a sense of postmodern art.

What surprised Zhou Mingyue was that even in the fierce battle and explosion before, there was no damage to this underground palace passage, which made him couldn't help but be amazed.

However, he did not spend his time studying such a passage, but continued to move forward.

The passage sloped slightly, and after a thousand miles, a tall iron gate blocked the end.

Zhou Mingyue stepped forward and reached out and knocked on the iron door.

Although the iron gate is rusty, it is at least more than three meters thick from the echoes heard.

And the walls of the passage are impregnable!

In this way, it is impossible for the iron gate to be blown open and destroyed, and the same is true for the passage wall.

Now the problem comes, I don't have the key.

Judging by the keyhole on the iron door, the matching key is at least two meters long, and if it is made of metal, its weight will not be less than 100 kilograms.

With such a heavy object, the big leader shouldn't take it away when he escaped, right?

According to the report of the pursuing arquebusier, the great leader fled without even a carriage, but more than a thousand cavalry guards, and even the chief himself was on horseback.

After thinking about it, Zhou Mingyue immediately issued a new order.

Look for the two-meter key.

The process of finding the key this time is much more difficult than finding the entrance to the dungeon.

After all, this thing can be moved, just find a place to dig a few meters deep, bury it, and replace it with whoever comes, and if you want to find it, the difficulty is simply looking for a needle in a haystack.

The search lasted for three full days.

The next day, the news came that the front-line Rearthur army had been defeated by Nias City, and a large number of defeated Rearthur soldiers were desperately rushing towards the city under the pursuit of Nias City's army.

Zhou Mingyue ordered the whole army to be on alert, and he was mentally prepared to fight a blocking battle.

As a result, on the morning of the third day, before noon, the key was found.

The Grand Leader hid the key under the floor of the dormitory where he least liked to live before escaping.

Well, this one is really hard to find.

After all, even if he was ruthless, it was hard to say that anyone would have thought that the big leader was hiding in his least favorite dormitory.

What really made Zhou Mingyue find the key was a maid in the palace of the great chief.

This lady-in-waiting was originally the most popular handmaiden of the great chief, and it is said that she bore him two sons.

But as fate would have it, although this big leader was not the emperor, his status like the emperor made the big leader's palace as full of intrigue as the Forbidden City.

To put it simply, the maid's two sons hung up at a few years old.

And the reason that came out of the investigation was that the maid herself did not take good care of the two young masters.

In such a situation, how could the big leader give the maid a good look and directly beat her to the cold palace, well, it is the bedroom that the big leader doesn't like to go to the most.

But in fact, according to the maid, the two sons were actually the little wife of the great chief.

Whatever the truth of the matter was, it was conceivable how deep her resentment towards the Great Leader would be after the maid was sure that what she knew was the truth of the matter.

Therefore, when the big leader hid the key, the maid hid it early, so that she was not killed.

You must know that in that cold palace, except for the maids, no one survived, and there were many old friends of the big leaders.

In any case, this maid will do anything that harms the interests of the great chief. Diagram of the Avenue of the Heavens
