At this moment, Jian Ning looked up and suddenly saw the mirror directly opposite. It just shines out of the door. Jian Ning felt very strange, what was he doing with such a big mirror in the room as an old man, what made Jian Ning most concerned was that this mirror was not the bronze mirror here.

Its clarity is completely comparable to that of modern mirrors, and it is incredible that such a mirror can be made according to current technology, and it is still so large. There must be something big wrong with this.

Jian Ning thought about it and immediately stood up and walked towards the mirror opposite.

Under careful observation, Jian Ning unexpectedly found that there were some subtle traces on the surface of the mirror. But these traces, Jian Ning didn't understand what they meant.

Suddenly, Jian Ning moved her gaze back and forth between the door and the mirror, and finally she found something incredible. The twenty-six letters drawn on the door actually correspond to the scratches on the mirror.

"Haha, I finally understood, it turns out that the door is just a trick, and the real door is this mirror!" Jian Ning was very excited in her heart, and she couldn't help but applaud.

But after the fun, the question came again, there was a password, which of the twenty-six letters should be pressed to open the door? Jian Ning didn't dare to go up and press indiscriminately, if there was another organ, after pressing the wrong one, he directly took her life, then he would be very happy and sad.

Thinking of this, Jian Ning began to search in the room. This room is almost modern décor, very simple, nothing like the rooms here. There are a lot of decorations.

After looking around. Jian Ning finally found a piece of paper in a drawer of her desk. It is clearly written in English: The code of the door is the treasure.

Jian Ning could hardly believe it. It's so easy to get a password. But thinking about it later, this may be an unsolvable mystery for people in this era.

The people here don't understand English, and even if they find this piece of paper, they probably won't be able to decipher this sentence. And the reason why Zijin's master did this is probably to leave something useful for people from other worlds who are destined to come to this world in the future!

Thinking like this, Jian Ning put the paper back in its place, maybe he wasn't the last.

Returning to the huge mirror again, Jian Ning carefully but firmly pressed the English letters one by one. When the last letter was pressed, there was a "coax", and the mirror really turned!

Jian Ning was excited. What a design! The door was covered with a mirror. If you were an ordinary person, I'm afraid you would have been studying the English letters on the fake door opposite.

Jian Ning thought as she walked in. When the body is completely inside, there is a "click", and the door automatically closes, leaving no trace.

When Jian Ning heard the door closed, she was a little nervous, worried that she wouldn't be able to get out, but she thought that since she came in, she would definitely go out. I settled down a little. After walking through a small dark passage, it instantly brightened as day.

This chamber is huge. It could even be said to be twice the size of the outside room. There were no candles or advanced electric lights, but they lit the room as if it were daytime. Jian Ning unconsciously counted it, and there were actually nearly a hundred fist-sized night pearls in it.

Jian Ning was shocked, the price of these night pearls alone is probably a sky-high price, and sometimes even if you have money, you may not be able to buy them. It seems that Zijin's master must have been a character once!

Standing in place, as her eyes shifted, Jian Ning was even more shocked and couldn't close her mouth, because it was almost a small military factory here. Even if there are no modern cannon pistols, there are indeed weapons piled up here, and it can be vaguely seen that some weapons are made in imitation of modern weapons.

Jian Ning couldn't help but walk a few steps, and arrived at the only table in this room, looking at the things on the table, Jian Ning unconsciously exclaimed: "Dynamite!" ”

On the table was a freshly made explosive, which had been covered with a layer of dust, but it could be seen that it was probably the last thing that Zijin's master had made before leaving here. There were even some unused sulfur and saltpeter on the table, and looking at these things, Jian Ning was even more curious about who Ruan Zijin's master was.

Turning around and walking to the row of bookshelves next to the table, Jian Ning casually took out a book and looked at it, which was actually a manufacturing drawing full of weapons.

Looking at the yellowed pages, Jian Ning thought that it should be some years, and after putting the book back, he took a few more books on other shelves, most of which were books on the art of war, weapons and the like. There are also books that record the history of the continent.

Jian Ning didn't have time to read these books now, but carefully searched for them on the shelves. Yes, what she was looking for was whether she had the books she needed, such as notes, diaries and the like.

But after looking around, Jian Ning didn't seem to find it. Just as he was about to look elsewhere, out of the corner of his eye, he caught a glimpse of a box at the top of the shelf.

Jian Ning tiptoed and wanted to take it down, but her height was really not enough, no matter how hard she tried, she couldn't reach it. After looking around the secret room, she didn't see a single chair, and in her anger, Jian Ning had to move some thick book pads from the bookshelf and put them under her feet.

Finally got the box, and when she saw that it was not locked, Jian Ning opened it excitedly. I saw a thick codex and a letter inside.

Jian Ning opened the letter suspiciously, frowned slightly, and actually wrote it in English. Just a general look at it makes me feel shocked, and I can understand why it was written in English, because the letter records things that cannot be known to the people of this world. From this letter, Jian Ning also got what she wanted to know about this person who was also from another world.

At the beginning of the letter, it was stated that he was originally an expert in mechanics and bombs, and for some reason, he came to this era from 2020.

Because of his youth and vigor at that time, he used his knowledge to make a large number of extremely lethal weapons and sell them to various countries in order to obtain a large amount of money. However, after the gunpowder was manufactured, the war was completely ruined, and smoke erupted in many places. When he finally realized that he shouldn't use it for profiteering, he couldn't get out. The attention of all countries turned to him, and he became almost the target of public criticism, living under the hunt or assassination every day.

Later, due to fate, the emperor of Yuan Chu saved his life. At that time, Yuan Chu was still a weak and small country, suppressed and coerced everywhere, in order to thank him for saving his life at that time, he chose to help Yuan Chu occupy a place in this era of gunsmoke and competition.

With advanced weapons and his military talent, Yuan Chu's military strength increased greatly, and soon he was no longer controlled by others, and even had a tendency to approach the largest country at that time, Dongshangguo.

After Yuan Chu's position was stabilized, he became the most honorable person in Yuan Chu except for the emperor.

It was during that period in Yuanchu that he met the most famous weapon master at that time, but who had been hidden in Yuanchu Tianhua Mountain for many years. Because of his fanatical love for weapons, he became the only disciple of the weapon master. However, guess the relationship between Jian Ning and these two people is not so much a master and apprentice as a friend, because they can both learn from each other what they don't understand!

During that time in Tianhua Mountain, he began to practice martial arts, and because of his extremely high talent, it only took five years to achieve something, and there were few opponents at that time. But the good times did not last long, and soon after, the world was in chaos again, because Emperor Yuanchu continued to increase his military strength and his desire to dominate the world was also increasing.

At that time, he stepped in to stop it, but was rejected by Emperor Yuanchu and even placed under house arrest. At this point, the form has been out of control, not only involving the countries on the mainland, but even plunging the sea country outside the continent into a quagmire.

Seeing that history was about to change because of him, he regretted it, but he was powerless to stop it. In the end, he desperately got out of house arrest and went to the Wu Clan, asking to borrow the divine power of the Wu Clan to quell this catastrophe.

In the end, in order to save the people of the world, the Wu clan used all their strength to change the situation of the war at that time and destroy weapons that did not belong to this era. It is even a heavenly curse that within a hundred years, if someone rises up again, the whole country will no longer exist. At that time, everyone in the world knew that the Wu clan had a mysterious power since ancient times, and their curse never failed. Although I don't understand what it means that the state will cease to exist, no one dares to try.

Naturally, everything is something that must be lost, and the Wu clan has poured out the spiritual power of the whole clan to change their lives against the sky, and they have also paid the corresponding price for this. Since then, the entire Wu clan has lost a trace, as if they have disappeared from this world.

In this catastrophe, another one who paid a terrible price was the Binglan Country. Like the Wu Clan, after this great war, it disappeared, as if it had completely sunk into the sea.

Since then, he has lived in seclusion with his master, concentrating on the study of these weapons, but no longer bothering with the world.

Jian Ning suddenly had deep doubts when she saw this. The wars described here, as well as the Wu Clan and the Binglan Kingdom, did not see any mention of them when she checked the nearly 100-year history of Yuan and Chu!

With doubts, Jian Ning continued to watch, but the more she went to the back, the more incredible Jian Ning felt.

This person came here not only for his soul, but also for his body, which means that he is a complete crossing. For this reason, his body does not belong to this era, so the rate of aging and the lifespan are different from those here. He had roughly calculated that the five years he lived here were equivalent to one year for a normal person.

Seeing this, Jian Ning roughly calculated, this person who is seventy years old and only sixty from the appearance is already more than two hundred years old. (To be continued......)
