After deciding, Yan Feng began to contact Yat-sen through the spiritual network.

'Yat-sen, I have something to ask you. Do you have any history books about Mi State in your bookstore? ’

'Admiral? Do you need these kinds of books, and what era? Yixian was a little surprised after receiving Yan Feng's communication, and then asked about Yan Feng's request.

'Hmm...... It is mainly a book that introduces the civilization of the ancient rice continent. Yan Feng replied after thinking for a while.

'Okay, please wait, Admiral. I'll deliver the books to the office when I find them. ’

'Excuse me, Yat-sen. ’

You're welcome, I'll look it up first. After saying that, Yat-sen took the initiative to end the communication.

Yan Feng raised his head and said to everyone in the office, "I have already informed Yat-sen and asked her to help find books about the ancient civilization of the Mizhou Continent, and she will send the books over in a while, so let's wait first." ”

"Speaking of which, Admiral, where did this knife come from? I always felt that this knife seemed to have some mysterious power. South Dakota looked at the knife on the coffee table and said with some distraction, and North Carolina nodded in agreement.

Yan Feng looked at the two of them strangely, "Mysterious power, what is that, can you tell me specifically?" ”

"Well, how do you say that, uh...... Heck, I can't describe that feeling. Nandako's sad face still couldn't describe the feeling.

Beika raised his little head and thought for a while, and then said, "If you have to say it, it's a little warm and powerful...... Well, I can't describe it clearly. ”

"Admiral, you haven't answered my question, where did this knife come from?" Nandako, he saw that Yan Feng didn't answer, and she pouted a little aggrieved.

Yan Feng only then remembered that he hadn't answered the little fat man yet, so he smiled and said, "I'm sorry, I'll tell you, it's actually like this......"

"Is it about the only ship mother? What is the secret of this knife, and why is it placed in another dimension? After listening to this, Nandakota looked at the company curiously, and then carefully observed the knife.

In the end, she shook her head in distress and said, "No, I still don't understand, I don't know if I'm too stupid." I can't put into words how it feels. ”

"Well, if you don't know, let's not discuss this for now. Anyway, let's find out the origin of this knife first, and then let's study its secrets. Yan Feng smiled and touched Nandakota's head and said.

Nan Dako, after feeling Yan Feng's touch, he smirked happily, "Hehe, the Admiral's hand is so warm." ”

Lexington then said, "Admiral, if the door of each unique ship is the same artifact, then doesn't it mean that we need to read more history books of Aqua Blue?" ”

Yan Feng was a little irritated when he heard reading, "There are enough things, do you still want to read history books?" Ay...... Let's take one step at a time, but let's look into the problem with the knife first, and then ask where the gate found in the Governor's Palace is. Let's find other samples later, maybe it's not a cultural relic but something else? ”

"Speaking of which, this thing was found by the company when it opened the door, will it have any special connection with the company?" VV said as he looked at the business.

"By the way, didn't you say you could put this knife in your ship's space? Have you had anyone else try it? Yan Feng's eyes lit up after hearing VV's words, and he asked the company.

After hearing Yan Feng's question, Nagato replied, "I've already tried, and we can't fit this knife in the space of our ship, only enterprises." ”

"Then it is basically certain that this knife has some degree of connection with the enterprise, but it is not possible to find key clues for the time being." Yan Feng touched his chin and groaned.

"Knock knock" Just as several people were discussing, there was a knock on the door.

"Is it Yat-sen? Come in. Yan Feng estimated that it should be Yixian who came.

"It's me, Admiral, I'm in." Sure enough, Yixian outside the door opened the door and walked in after answering, still holding 3 books in her hand.

Yat-sen was a little surprised to see so many people in the office when he came in, but he still greeted everyone politely.

"Admiral, these three books are the ones that mainly tell about the ancient civilization of the Mizhou Continent." Yat-sen said as he put the book on the coffee table after exchanging greetings with everyone.

Yan Feng first thanked Yixian, "Trouble you for this trip, Yixian." ”

Yat-sen smiled softly, "It's okay Admiral, I'm very happy to be able to help you." ”

Then Yan Feng picked up the top book on the coffee table, and saw that the cover of the book read "The History of the Ancient and Modern Development of Mizhou". After checking the two books one by one, Yan Feng found that the names were "Exploration of the Ancient Civilization of the Mizhou Continent" and "The Three Ancient Civilizations - The Aborigines of Mizhou".

Lexington picked up the book on the three ancient civilizations at the bottom and said, "Admiral, why don't we take a look at this one first." Books that directly tell about the three ancient civilizations should be relatively easy to get clues. ”

Yan Feng nodded and agreed, "Okay, then put the book on the coffee table, and anyone who is interested can come over to help find clues." ”

Then everyone gathered in a circle with Yan Feng as the center and began to read the books. Lexington naturally sat on Yan Feng's left hand side, and South Dakota finally took the position next to Yan Feng's right hand after a fierce scramble, and the little fat man leaned happily on Yan Feng in the murderous eyes of other ship girls.

Yan Feng didn't care about the things around him, he flipped through the book and said while checking it, "Sure enough, this water blue star also has the existence of the three ancient civilizations on the American continent on the earth, and the knife we found should be the product of this ancient civilization called the Inpan Empire." He said as he pointed to a pattern drawn on the page.

"Well, this pattern looks very similar to the pattern on the knife." Lexington said as he picked up the golden knife and compared it to the pattern on the book.

The final result is just as Yan Feng said, this knife should be the product of this Inpan Empire.

Yan Feng continued to flip through the book and said, "Then the next question is, when was this knife made, and why was it put in another dimension. ”

However, unfortunately, until a group of people looked through three books, they could only confirm that the knife was made at the end of the Pan Empire, but there was no understanding of why it appeared in another dimension.

Yixian looked at Yan Feng's frowning and thoughtful expression and guessed, "Admiral, could it be that this knife was not put into the other space because of the people of the Pan Empire, but was put in after the people of the Pan Empire found this knife." ”

"Possibly, but then it's hard to keep looking. After all, how this knife ended up in the outside world, and whose hands it ended up in is completely black. Yan Feng scratched his head and said unwillingly.

VV lowered his head and thought for a moment before saying, "Admiral, I have an idea. ”

Yan Feng lowered his head and said to VV who was sitting on his right hand in South Dakota, "Tell me about it." ”

"I'm wondering if I need to gather the seven secret treasures before I can unlock their secrets." VV replied with his chin in his left hand.

After hearing VV's words, the company nodded and said, "What VV said makes sense, although I can feel the connection with this knife, but I always feel that something seems to be missing, maybe I really have to gather 7 secret treasures to unlock the secret." ”

"Well, since the relevant personnel of the company said so, there should still be some truth." Yan Feng nodded and said.

"Then let's put the knife on hold for now, and I'm going to go to the terminal room to send a report to the Doge's Palace and ask about the door. You go and do your own things first, and I'll let you know when you have the results. Madam, I'm sorry for you to help with the paperwork first. Yan Feng stood up after closing the book and said to everyone.

As a secretary, Lexington was the first to agree, "Okay Admiral, leave the paperwork to me." ”

Later, when Yan Feng went to the terminal room, the other ship girls also left separately to do their own things, and Nandakota was still a little reluctant when he left, after all, it was rare to have the opportunity to get so close to the Admiral, but in the end she was still pulled away by the company.

"Let's go, little fat man, I don't feel at ease when the raider is watching the store alone." The business said as he took South Dakota's hand.

When he was pulled away, Nandakota reluctantly looked back at Yan Feng, "Enterprise, don't pull me, I want to see the admiral more." ”

"Who cares about you Admiral, let's go." The company dragged South Dakota down the stairs mercilessly, and North Carolina also left the Admiral Building after looking for a hug.

When Yan Feng came to the terminal room, his sister-in-law Saratoga was still checking the news on the terminal, and when she saw her brother-in-law coming, Saratoga dropped the mouse and keyboard and pounced.

"Brother-in-law, how are you doing over there? Any progress? After throwing herself into Yan Feng's arms, Saratoga asked with a smile.

Yan Feng kissed his sister-in-law's moist red lips and explained gently, "I just know the origin and approximate manufacturing time of that knife, and I don't know anything else." ”

Saratoga's cheeks flushed slightly after receiving Yan Feng's kiss, she mustered up the courage to kiss Yan Feng back and asked, "So, brother-in-law, are you here to inspect the work now?" Gaga is almost ready to take care of this side of things. ”

Yan Feng said dotingly, "Okay, I know you're amazing." However, my brother-in-law came to report the content of this mission to the Governor's Palace, and by the way, there are some things to ask the headquarters of the Governor's Palace. Saying this, Yan Feng's face became serious.

After seeing her brother-in-law's face, Gaga knew that she had something important to do, so she jumped out of Yan Feng's arms and asked, "Is something wrong?" ”

"Well, that's what we just guessed......" Yan Feng told Saratoga that the Governor's Palace might know about another gate.

"I see, but that would explain why the Governor's Mansion would guess the usefulness of the only shipwive." Saratoga muttered.

Yan Feng pulled out a chair and sat down in front of the terminal, turned his head and asked, "So, Gajia, are you going back to the office now to help your sister with paperwork, or are you here to watch me send messages?" ”

"Hehe, that's still going to be said. With my brother-in-law, of course. The sister-in-law said with a snicker, after all, there are very few opportunities to be alone with Yan Feng now.

Yan Feng smiled and patted Gaga's head and said, "Okay, don't make trouble next to you, I'm going to start getting down to business." After finishing speaking, Yan Feng turned around and began to type on the keyboard.
