The bad husband wanted to bring his second wife into the house, so I turned around and became his st

"Shengyuan, who do you think did this?"

Lu Shengyuan was silent for a moment and then spoke slowly.

"This matter involves a wide range of issues, so it's hard to draw a conclusion at this point. However, we can start with this letter and see if we can find any clues."

The two discussed for a moment and decided to act separately.

Lu Shengyuan was responsible for investigating the source of the letter, while Lin Wanqing was responsible for searching the mansion for possible clues.

As night fell, the mansion was silent.

Lin Wanqing and a few confidants searched the study carefully, not missing any corner.

She knew in her heart that if she wanted to find out the truth, she had to find clues first.

As time passed, Lin Wanqing's mood became heavier.

She searched the entire study but found nothing.

Just when she was about to give up, an unexpected discovery caught her attention.

Among the decorations next to the bookshelf, she found a note with vague numbers hidden on it.

Lin Wanqing's heart moved, and he quickly checked it carefully.

She found that the numbers on the note seemed to have some pattern, but she couldn't decipher it for a while.

Just then, Lu Shengyuan walked in.

He glanced at the note in Lin Wanqing's hand, and a hint of doubt flashed in his eyes.

"what is this?"

Lin Wanqing handed the note to Lu Shengyuan and told him her discovery.

Upon hearing this, Lu Shengyuan frowned and pondered for a moment.

Suddenly, his eyes lit up, as if he had thought of something.

"Wanqing, look at these numbers. Do they look like a special code?"

Lin Wanqing was stunned when he heard this, then he reacted.

"You mean... these numbers are actually a code?"

Lu Shengyuan nodded, a determined light flashing in his eyes.

"Yes, I've seen this kind of code recorded in an ancient book before. As long as we find a way to decipher it, we'll be able to know the true message on the note."

Lin Wanqing gently stroked the edge of the note with a deep gaze.

"Shengyuan, what exactly did this person intend by leaving behind such a secret object? Was it a provocation or a warning?"

Her voice was soft but held a firmness that could not be ignored.

Lu Shengyuan took over the conversation and slowly swept his eyes across the study.

"This person acts so secretly. This note might be the bridge used by the unknown traitor in the Prince's Mansion to pass on information."

There was a hint of coldness in his words, yet he remained calm.

Hearing this, Lin Wanqing frowned slightly, her worry evident in her expression.

"If this is true, we must be even more cautious and not let this traitor's plot succeed."

Lu Shengyuan patted Lin Wanqing's shoulder gently to comfort her.

"My Lord, don't worry too much. Although the Emperor hasn't said it explicitly, I can sense that he isn't completely indifferent to this matter. He simply values ​​the final outcome more."

He paused and continued, "The most important thing for us right now is to find this traitor and expose his conspiracy."

Lin Wanqing took a deep breath and put the note away again.

"You're right. We must find the traitor. However, before that, we still need to decipher the code."

Lu Shengyuan nodded in agreement, walked to the bookshelf nearby and started looking.

"I remember that ancient book should be placed here..."

As he spoke, he searched through the bookshelf.

After a while, he finally found a yellowed ancient book, opened it to a certain page, and handed it to Lin Wanqing.

"Look, here is a record of how to decipher that code."

Lin Wanqing took the ancient book and read it carefully, while Lu Shengyuan stood aside and waited quietly.

After she finished reading, the two discussed their next plan.

It was late at night, but the lights in the study were still bright.

Lu Shengyuan and Lin Wanqing sat side by side, carefully studying the numbers on the note under the light.

As time went on, the expressions of the two men gradually became solemn.

After some deliberation and comparison, they finally found a way to decipher the code and successfully converted the numbers on the note into a piece of text.

However, the message conveyed by this text made them feel shocked and uneasy.

It turned out that the note contained the defense map and patrol time of the Prince's Mansion!

"It seems that we are really being targeted."

Lu Shengyuan took a deep breath and tried to calm his inner anger.

Lin Wanqing also frowned, his face full of worry.

"Who is this traitor? Why did he do this?"

There was a hint of confusion and puzzlement in her words.

Lu Shengyuan was silent for a moment, then slowly said, "Perhaps, his purpose is not just to pass on the message..."

Before he could finish his words, there was a sudden sound of hurried footsteps outside.

Immediately afterwards, the door of the study was pushed open and a guard walked in hurriedly.

"My Lord, Princess, this is bad! There's an assassin in the mansion!"

The guard's words startled Lu Shengyuan and Lin Wanqing. After looking at each other, they immediately stood up and walked out.

"Immediately strengthen the security of the palace and let everyone be vigilant!"

Lu Shengyuan gave orders quickly as he walked.

Lin Wanqing followed closely behind, her heart filled with worry and uneasiness.

When they arrived at the front yard of the palace, they saw a group of guards fighting with a figure.

Lu Shengyuan and Lin Wanqing immediately joined the battle and fought against the black shadow together with the guards.

After a fierce fight, they finally subdued the black shadow to the ground.

However, when they saw the black shadow's appearance clearly, they couldn't help but be stunned.

It turned out that this black shadow was actually a guard in their palace!

"Tell me! Who are you? Why are you doing this?"

Lu Shengyuan questioned angrily, with a hint of coldness in his eyes.

The guard struggled on the ground but refused to speak.

At this moment, Lin Wanqing suddenly discovered something strange about him.

"Shengyuan, look behind his ears!"

She pointed behind the guard's ear.

Upon hearing this, Lu Shengyuan looked over immediately and saw a tiny tattoo pattern there.

"Is this... the mark of a secret guard?"

He frowned, his heart full of doubts and confusion.

The secret guards are the most secretive existence in the palace, and their identities are only known to the emperor and a few people.

Why does this guard have the mark of a secret guard on him?

Could it be that... he was sent by the emperor?

But why did the emperor do this?

Wasn't he asking them to investigate the traitor? Why did he send someone to the Prince's Mansion as an assassin?

Lu Shengyuan was full of doubts, but he couldn't figure it out.

At this moment, the guard suddenly broke free from his restraints, jumped up and tried to escape.

Seeing this, Lu Shengyuan immediately chased after him and fought with him again.

This time, he did not hold back, but used all his strength to subdue the guard to the ground and tied him up tightly with ropes.

"Put him in the dungeon and interrogate him strictly!"

Lu Shengyuan ordered angrily, then turned and walked towards Lin Wanqing.

"Wanqing, are you okay?"
