The daughter of the emperor is beautiful and holds the power over the world

Si Yan said calmly, "Okay, give the antidote to Boya first, and then we'll go in together."

Boya didn't say anything. He understood A Yan's thoughts. Even if the master knew how to open the vault, he would not be able to transport so much treasure out of Daxuan.

In other words, even if he gave the vault key to the master, it would be useless.

But he also knew that his master would not easily agree to give him the antidote.

A smile appeared on Bo Yuan's lips: "Miss Si, I am only good at poisoning, not detoxifying."

The poison in Boya's body is the only bargaining chip he has.

If he detoxified Boya, he would get nothing.

Si Yan's expression was as cold as ice: "If that's the case, then there's nothing more to talk about. If you don't detoxify Boya, there's nothing to talk about."

Si Yan pulled out a dagger from the scabbard and stared at Bo Yuan with cold eyes.

The candlelight on both sides of the wall illuminated the woman's face. She was extremely beautiful, cold, and exuded a dangerous aura.

Seeing the resolute look on Si Yan's face, Bo Yuan smiled and said, "Miss Si knows very well that we have reached a life-and-death struggle."

"You are wrong. You will die."

Si Yan's stern eyes swept across Bo Yuan and the dozens of men in black behind him.

Bo Yuan was slightly stunned: "Miss Si is quite arrogant."

Si Yan was too lazy to talk nonsense, and waved the dagger towards Bo Yuan. The dagger swept across Bo Yuan's neck, and Bo Yuan quickly retreated.

The men in black behind Bo Yuan rushed up, and Si Yan engaged in hand-to-hand combat with them in an instant.

The men in black already knew Si Yan's identity and originally thought that a woman was not worth mentioning. However, after this fight, they realized that this first-rank female official of Daxuan was not just a show-off.

Her moves were ruthless, her attacks were quick and accurate, and in the blink of an eye, several men in black had already fallen to the ground.

Boya rushed up and brandished his sword, and together with Si Yan, he charged into the camp of the men in black.

Si Yan said to Boya, "Just wait on the side!"

Boya's body could not withstand the battle.

These people still hope that Boya will get the key to the vault and will not hurt Boya again.

"Ayan, come with me." Boya said to Si Yan.

He knew the strength of these men in black. They were all trained by their master himself, and their martial arts skills were no worse than those of the hidden masters of the Bo family.

Boya suddenly activated the mechanism, and two huge rocks fell on his head. After a few screams, several men in black were smashed into meat paste.

Boya and Si Yan quickly moved forward.

There were stairs leading down in front of them. Si Yan followed Boya inside and it was pitch black.

Boya took out a tinderbox and instantly illuminated the steps.

The two of them kept walking down and entered a secret room again. The atmosphere inside was much colder.

This secret room is extremely large and high, and there is water inside, which looks like a hidden river or an underground spring.

Boya pointed to a lotus platform in the middle of the water and said to Si Yan, "Ah Yan, if you go through here, you can get the key to open the vault. But there is no road here, so you need to swim over."

Si Yan raised his eyes and glanced at the lotus platform in the water: "I'll get it."

Boya grabbed Si Yan's hand and said, "The water is too cold."

At this moment, dozens of black figures jumped into the water and swam towards the lotus platform.

Si Yan was about to rush forward when Boya grabbed her wrist tightly.

Si Yan understood that this was Boya's strategy.

There was no key on the lotus platform at all.

"what--"

Suddenly, someone in the water screamed, and many people in black looked painful, slapping and fighting in the water, struggling desperately.

It turned out that there were many poisonous snakes in the water. The man in black rushed over and was bitten.

At this time, Boya opened a secret door and walked in with Si Yan. Screams were still coming from outside.

Boya was a little tired and couldn't help but take a breath. When he looked up, he saw Boyuan right in front of him.

"Xiaoya, you've really grown up. You even lied to your master."

Behind Bo Yuan, the number of men in black had been reduced by half.

Boya was silent for a moment, then turned to Boyuan and said, "Master, do you want my life? You saved my life, and now I'm returning it to you."

Boya said this, letting go of Si Yan and walking towards Boyuan step by step.

Si Yan paused for a moment, but ultimately did not move.

Bo Yuan's expression darkened, and his tone softened: "I don't want your life, I just want the key to the vault, I just want the Bo family's property."

He looked deeply at his disciple and said, "Beimang State is strong in both military and cavalry, and its national strength is formidable. Unifying the world is the inevitable trend. As long as you donate all the wealth of the Bo family to Beimang State, we will be master and disciple forever. The Emperor of Beimang State will also confer the title of Marquis on you, and the Bo family will be forever glorious."

"Master, I am from Daxuan. My family has been from Daxuan for generations. Boya will never betray his ancestors and Daxuan."

"Xiaoya, don't force Master. You know, Master has always loved you."

Boyuan said this with a look of pity in his eyes.

"what--"

Suddenly, Boya stomped on the mechanism on the ground, and Boyuan's feet were empty and he fell down.

Boya quickly closed the mechanism and ran forward with Si Yan. The man in black behind him was busy rescuing Bo Yuan and could not catch up for a while.

Boya took Si Yan through various secret rooms and finally came to a place with bright candlelight.

The tablets of the ancestors of the Bo family and the heads of the Bo family throughout the generations are enshrined here. An incense table is set up in front of the tablets, and offerings are placed on it.

Boya stepped forward and pressed a mechanism on the altar, and the tablet of Bo's ancestor suddenly turned around.

Boya took out a bunch of keys, five in total.

"Ayan, this is the key to the Bo family vault, but before we can reach the vault, we still have to decipher many traps."

Boya walked towards Si Yan with the keys. "The vault is in the back mountain, surrounded by thick walls made of black iron. Without these five keys, even with Thunderbolt, I'm afraid you won't be able to get in."

"Ayan, here's the key." Boya said, as if relieved, and a mouthful of blood flowed out of his mouth.

He turned his head away and raised his sleeve to wipe it. His white clothes had turned blood red.

"How do you feel now?" Si Yan took the heavy keys and supported Boya, "Let's go out first."

"Ayan..."

As Boya spoke, his body could no longer support him and he fell backwards.

Si Yan quickly supported Boya. Boya looked at the woman in front of him and blinked, as if trying to confirm: "Are you Ah Yan?"

Si Yan felt something was wrong, only to see Boya shaking his head vigorously, and his eyes seemed to have regained clarity.

"Ayan, this is the map leading to the Bo family vault. With it, you will be able to reach the vault unimpeded and find the exit. Go by yourself, Ayan."

"What nonsense are you talking about?" Si Yan said solemnly, "We came in together, and we must leave together."

"Ayan, go!"

Boya held his head, which seemed to be about to explode, and said, "The poison in my body seems to have the effect of paralyzing the brain. Ah Yan, you should leave quickly..."

Boya looked at the woman in front of him, and as he looked at her, he felt that she was no longer the same as before.

Si Yan also noticed that something was wrong with Boya: "I'll carry you on my back."

Boya shook his head and pushed away Si Yan who was trying to help him: "Hurry up and leave. Leave by yourself. If you don't leave, I won't be able to control myself..."

Boya could feel that there was an uncontrollable force in his body, which was about to make him lose his mind.
