The daughter of the first wife is reborn and marries a rich family again

Yu Caiwei nodded and said with a firm look: "Brother is right, we must find out the truth as soon as possible. Su Qing, you and I will go to the library together, and we will study the "Mysterious Records" carefully to see if we can find some clues from it."

Su Qing nodded and responded, "Okay, let's go now." The two quickly left the lobby and walked towards the library.

On the way, they passed by several servants. One of the servants said in surprise: "Second Miss, you just came back from the front line, why don't you take a rest?"

Another servant replied, "Yes, you guys are really working so hard!"

Yu Caiwei smiled and replied, "Thank you for your concern, but we must hurry now. This "Mysterious Records" may contain the key to solving all the mysteries."

Upon hearing this, a young maid exclaimed: "Oh my God, is this book really that important? I heard that even the emperor has issued an edict to support your research!"

Another servant nodded in agreement: "Indeed, the Second Miss has become a big celebrity in the Duke's Mansion. We are all very envious and admire her."

Yu Caiwei shook her head slightly and smiled: "This is not my personal achievement, but the result of everyone's joint efforts. Without your support, we would not be able to carry out the research smoothly."

After entering the library, Yu Caiwei and Su Qing immediately started their intense work. Su Qing carefully read the ancient books, while Yu Caiwei carefully took notes. They exchanged their thoughts with each other from time to time, their eyes full of determination.

At this time, Xiao Cheng's voice came from outside the door: "Caiwei, Su Qing, come in."

The two raised their heads, put down their work, and walked to the door. Seeing Xiao Cheng's serious expression, Yu Caiwei asked with concern: "Brother, is there anything important?"

Xiao Cheng nodded and said, "I just received intelligence that a small team of the enemy seems to have sneaked into the city. They may have a traitor, and their goal is very clear, which is to take away the "Mysterious Records."

Yu Caiwei's eyes suddenly became sharp, and she said in a deep voice: "We must take action to protect this book. At the same time, we must find the traitor, otherwise we will always be in a passive situation."

Su Qing also added: "Yes, we can set a trap to lure them out. If we can capture them alive, we can interrogate them for more information."

Xiao Cheng nodded in agreement and said, "That's a good idea. Let's make a detailed plan now. Caiwei, you continue to study the ancient books here, and I will set traps outside."

Yu Caiwei nodded and said, "Okay, let's divide the work and work together to solve these problems as soon as possible."

After a quick discussion, the three of them took action. It was already late at night, and the Duke's Mansion was shrouded in a tense and mysterious atmosphere. Everyone was preparing for the upcoming new battle.

While they were discussing, an old butler hurried into the study and reported to the old lady who was reading the documents: "Madam, we just found traces of the enemy again. It seems that they will not give up easily."

The old lady frowned and said in a deep voice: "Yu Caiwei and Su Qing are extraordinary in their abilities. I believe they can handle this. But we can't let our guard down and continue to strengthen our precautions."

Suddenly, a servant rushed into the room, shouting breathlessly, "Madam, it's bad! Someone tried to break into the library! One has been caught!"

The old lady stood up suddenly and said sternly: "Bring him here quickly! We need to find out their purpose!"

After a while, several guards brought a strange man with a terrified face to the study. When the man saw the old lady and the others, he immediately knelt on the ground, trembling all over and said, "Please... please spare me! I'm just a small fry, I don't know anything!"

The old lady asked coldly, "How did you get into our Duke's Mansion? Who ordered you to do this?"

The man trembled and finally mustered up the courage to speak: "It's...some people in black clothes! They threatened me to help them enter the mansion! I didn't dare to disobey..."

At this time, a young maid said in surprise: "The one wearing black clothes? Is he related to those unknown forces last time?"

Another person added: "It's very likely! These people must have planned it!"

The old lady nodded solemnly and turned to the guards: "Take him away for strict interrogation. Make sure he confesses everything he knows!"

At this moment, there was another sound of hurried footsteps outside, and a soldier came running to report: "Madam, the second young lady and Miss Su Qing are back, and they seem to have discovered something!"

The old lady stood up hurriedly and walked out. Everyone followed her and headed to the hall.

In the hall, Yu Caiwei and Su Qing were standing in front of the map, with a smug smile on their faces. Seeing the old lady coming in, Yu Caiwei immediately stepped forward and said, "Grandma, we found a crucial clue in the "Mysterious Records". This passage mentioned a secret book called "The Book of Shadows", which records a lot of profound knowledge in detail. According to our speculation, the enemy's goal is not only the "Mysterious Records", but also to find the "The Book of Shadows"!"

The old lady's eyes sparkled when she heard this: "So, the forces behind them are more massive and complex than we thought. We need to be more careful."

Su Qing continued, "Yes, and we have also found some suspicious people and are already planning to arrest them."

At this time, a servant ran in excitedly: "Madam, we have just captured a few more assassins, and their identities and backgrounds are very suspicious!"

The old lady nodded with satisfaction, turned to look at Yu Caiwei and Su Qing, and praised: "You did a good job. Next, we must not only defend, but also fight back. Find all the enemy's hidden stakes and destroy their plots."

Yu Caiwei nodded firmly, and Su Qing also smiled confidently. Everyone responded in unison, ready to face the new challenge.

As the night deepened, the atmosphere in the Duke's Mansion became more and more heated. Everyone was full of fighting spirit, looking forward to uncovering the real culprit behind all this.

Finally, Yu Caiwei and Su Qing returned to the library and began to study the Mysterious Records in depth. Yu Caiwei suddenly stopped what she was doing and whispered, "Su Qing, do you think we can solve all the puzzles? Is this really arranged by fate?"

Su Qing looked up at her and smiled, "Whether it is fate or not, at least now we are working towards the same goal. Isn't it?"

Yu Caiwei nodded and responded with a smile: "Indeed. Then let us work together to uncover all the mysteries! No matter what the result is, we will never back down."
