It turned out that this man's name was Curzon, and he was another Komang. Because of his burly body and tall physique, he is very suitable for lurking in the army, so for many years, Curzon has been arranged by Kou Yunwu to lurk in the army. During this period, he only came back a few times, all of which were only a few days, so Kou Song only knew that Kou Yunwu had a biological daughter and had met a few times, but he didn't know that Kou Shu became the queen.

Kou Shu frowned: "In this way, what is going on in the war in the northwest, and why is Dad called a cowardly for no reason, do you know it?" ”

Curzon shook his head, and said with a blank look on his face: "I was no longer in the army at that time, and I returned to the Kou Mansion with my master. I don't know exactly what happened in the army. ”

Kou Shu's expression tightened: "You said you were with your father at the time?" ”

"yes." Curzon nodded, "The master urgently summoned me one night, only saying that there was an urgent matter to deal with, and then I returned to the Kou Mansion with the master overnight, but it didn't take long for the master to return, and he lost contact with me, and then he heard the news that the master was arrested, and then ......."

Kou Song didn't say any more, Kou Shu and Yuan Ming both understood, and then the news of Kou Yunwu's death came out.

"Do you know what happened when your father went home with you that day?" Kou Shu looked up, her eyes shining with a different light.

Curzon shook his head: "The master only said that it was an extremely urgent matter, and he and I rushed back to the Kou Mansion day and night. ”

Kou Shu was stunned for a moment, and asked, "Daddy, did you say anything else?" ”

Curzon frowned, as if thinking about something, and after a while, Curzon raised his head and said, "The master seems to have said that he hopes his suspicions are wrong. ”

"I hope my suspicions are wrong?" Kou Shu frowned, and then asked, "Then why did you come to Kou Mansion late at night?" ”

Curzon's eyes glanced at Yuan Ming and said, "First, I want to try my luck and see if I can meet someone who is also Kou Mang." Second, I wanted to find out why the master died. ”

"Oh?" Kou Shu raised her eyebrows, "Did you find anything?" ”

Curzon shook his head and said, "I've been exploring the mansion every day in the past few days, and finally let me find that there is a secret room in the master's study, but I didn't have time to enter it yesterday, and I planned to go in and have a look today." ”

Kou Shu was stunned - there was actually a secret room in Daddy's study? I never even knew about it.

Seeing Kou Shu's expression, Curzon guessed the general idea in his heart, nodded and said, "I also found out about this matter just now, if the eldest lady is willing, go and take a look with me." ”

Kou Shu nodded, and several people came to Kou Yunwu's study together.

Curzon approached Kou Yunwu's desk, slowly reached out and touched a bronze lion statue next to the table, his fingers were slightly clasped, and the sound of stones moving and grinding against the ground came, only to see the wall behind Curzon slowly fade back, revealing a path.

"Miss, this is the secret passage I discovered." Curzon turned his head and said to Kou Shu. After that, Kou Shu took the lead in stepping forward, and Yuan Ming motioned for Kou Shu to follow him forward, and he was behind the palace.

The passage of the secret room was not long, and Kou Shu only walked a few steps before finishing it.

There was no light in the dimly lit secret room, so Yuan Ming lit the flint in his arms and wiped a small oil lamp to come in. I saw that on the table in the secret room, there was an extremely simple iron box, which was carved with extremely complex patterns, and at a glance I knew that the workmanship was exquisite and expensive.

"Heavenly Box!" Curzon's voice was a gaffe.

"This is the master's heavenly box?" Yuan Ming was also a little surprised, and turned his head to ask.

Curzon nodded, the Heavenly Machine Box is a box obtained by chance from Kou Yunwu's early travels in the rivers and lakes, the biggest feature is that it has four and forty-six built-in organs, and it takes a lot of complicated steps to open the Heavenly Machine Box.

"Daddy put this box here, what important things are stored in it?" Kou Shu asked,

Curzon frowned, but did not speak. Slowly stretched out his hand and touched the receiver of the day, wanting to see how the receiver was. The moment he touched the box, a hint of doubt flashed in his eyes.

Immediately, he stretched out his other hand, picked up the heavenly machine box with both hands, tiptoed cautiously, and looked up at Yuan Ming, as if there was something in his eyes. The two hands moved forward slightly, and gave the heavenly machine box in his hand to Yuan Ming.

Yuan Ming was puzzled, but he still reached out and took the Heavenly Machine Box in Kou Song's hand, and the moment he touched the box, a trace of doubt flashed in his heart: "Pig iron? ”

Curzon nodded, confirming his thoughts, "That's right, this is pig iron, not dark iron. Curzon turned his head and said to Kou Shu, "Miss, this day the machine box is fake. ”

"Fake?" Kou Shu frowned and asked.

Curzon nodded, pointed to the heavenly machine box, and said, "Although this box is exquisitely carved, beautifully made, and copied and imitated extremely realistically, his material is not dark iron, but pig iron. ”

Curzon explained that the Heavenly Machine Box is the masterpiece of the old man's life, and the old man has a habit, the iron utensils he makes are all made of dark iron, which is very rare, the sound of hitting is melodious and crisp, the echo lingers for a long time, and the skin is cold to the touch. Pig iron is the most common form of iron smelting, although the appearance and color are similar to those of dark iron, but the touch is more dull and rough, and the sound is short and dull.

After that, Curzon tapped the box lightly, and his voice was indeed a little deep.

"Pig iron and dark iron are very similar in appearance and color, and you can't see the difference between them at all," Yuan Ming explained. Only when he and a martial arts practitioner like Curzon have been dealing with sword-tipped iron for many years, will they feel the difference. This is also the reason why Curzon gave the box to Yuan Ming just now and wanted Yuan Ming to confirm.

"So, this box is a fake?"

Curzon nodded, and with a slight effort, he used his sword to split the switch on the box, and when it was opened, it was empty.

"Did Daddy say this box that day?" An idea flashed through my mind, but it was hard to grasp.

Both of them shook their heads, Curzon hesitated for a moment, and said, "Miss, I have a guess. ”

A glimmer of light flashed in Kou Shu's eyes: "I don't know if you and I think it's the same." ”

The two looked at each other and said in unison: "Armament map!" ”

The moment they said those three words, the three of them all felt that the temperature around them dropped suddenly, the defense map is the most important bottom line of the country, as a border general, the defense map is more important than their own lives, if the defense map is lost, it is equivalent to exposing the entire defense line of the country to the border pass, to all the border generals and the lives of the people.

If Daddy really put the arming map in this box, it would be reasonable, but now, where is the real Tianji box?
