The two of them walked down the dark passage, one in front and one behind. After a while, Shen Huaixu felt that he had overthought it before.

The mechanism set up by Qiao Man was deadly enough for ordinary people, but it was child's play for the two of them.

After successfully dodging the last arrow, the two found themselves in a dark and damp basement with boxes of gold piled up in the corner. Chen Huaixu threw a stone in his hand onto the open space in the room, then stopped and looked around - there was no change.

"After dealing with Qiao Man for a long time, I always feel that I have become a little abnormal..." Shen Huaixu breathed a sigh of relief and found a reasonable excuse for his restless suspicion.

Upon hearing this, Fu Yin said seriously, "It's not that you're abnormal. There is indeed something strange here, but I just don't know where it is."

Hearing him say this, Shen Huaixu couldn't help but feel nervous. He became more alert to everything around him, "It's okay, let's be careful."

She tugged at Fu Yin's sleeve and said, "Let me make this clear first. If anything unexpected happens, don't try to resist. Run if you can. Of the thirty-six strategies, running away is the best. Saving your life is the most important thing."

Fu Yin responded, retracted his spiritual power, and slightly leaned to the side to block Shen Huaixu. He said, "There are three rooms here in total. The weapons and potions are in the innermost one."

Shen Huaixu opened a box nearby and was dazzled by the golden light. She squinted her eyes and looked inside. The box was filled with gold bricks of the same size, neatly stacked.

At the same time, a strange smell also occupied Shen Huaixu's nostrils. She leaned in to smell it and asked doubtfully: "Do you smell a strange smell?"

Fu Yin walked over to Shen Huaixu and sniffed carefully, "No. What is that smell?"

Chen Huaixu looked at him in confusion. Logically speaking, Fu Yin's sense of smell was as sensitive as hers. The smell was not strong but it was not so strong that she could not smell it at all. She was silent for a moment, wondering if it was the smell of money that only she could smell?

She followed the source of the smell and collected all the boxes of gold she came across. Soon she came to an iron box.

The iron box was tightly covered by the wooden box containing gold, and only after Chen Huaixu moved it like a bandit was it able to see the light of day again.

Just as Shen Huaixu was about to touch her, Fu Yin grabbed his wrist.

"Don't touch it!"

She remained motionless, her eyes scanning the iron box. The box was not large, but seemed quite heavy due to the multiple reinforcements. She asked Fu Yin, "What's in it?"

Fu Yin's expression was somewhat ugly. He met Shen Huaixu's gaze and shook his head, "I don't know."

Chen Huaixu's heart trembled, and he pulled Fu Yin back a step.

So far, this is the first time I have seen something that even Fu Yin cannot detect.

"Its outside has been reinforced. Could there be some living thing inside? Or a dead object with radioactive effects?" Shen Huaixu guessed.

Fu Yin fell into deep thought.

He had never seen anything dead that his spiritual power could not capture, but he had heard the clan leader mention living things before. However, how could such a thing appear here? Even if there was space, Qiao Man could not bring it here.

Chen Huaixu continued, "How about trying it out? Things that can fit into the space are dead, and things that can't fit into the space are alive. How about that?"

She looked at Fu Yin, but found that his face was as dark as water, and his expression was gloomy and terrifying. She couldn't help but tremble with fear. She stepped forward and pulled his sleeve. The gloom on Fu Yin's face immediately receded like the tide, as if the previous glance was just her illusion.

"Don't be afraid." Fu Yin saw Shen Huaixu staring at him, and his eyebrows softened. His voice was low and pleasant, "I just remembered that the clan leader once told me that in our world there is a creature called sand boa that is not only tenacious, but also has a strong reproductive ability.

They once occupied an entire planet. Because of a rare metal on that planet, they and humans had fought several wars. Even with advanced weaponry, humans were unable to completely eliminate them.

Sand boas are the only creatures that cannot be captured by psychic powers. The sounds they make can, in turn, damage the psychic's brain, causing them to fall into a coma. If this box contains sand boas, Qiao Man's purpose in bringing it here is self-evident."

From Fu Yin's words, Shen Huaixu could sense how difficult the things in the box were. However, she still had some doubts in her heart. Thinking that now was not the time to speak, she only said: "Qiao Man can bring it here, I should be able to put it into the space as well. It is not advisable to stay here for long. Let's take the things and leave."

"Let me do it." Fu Yin stood between Shen Huaixu and the iron box, glancing at it. "The thing inside has been quiet. It should be dormant and can't hurt me."

In fact, there is another consideration for Fu Yin.

When the patriarch talked about the sand boa, he emphasized the impact of the sand boa on Fei Yuan, and only briefly mentioned the war between the sand boa and humans. He didn't know how the sand boa would harm humans.

Since they noticed the box and no sound came from it, Chen Huaixu did not stop it.

She quickly searched the room and cleared out everything, then returned to the first room to meet Fu Yin, but the iron box was gone.

When the two left the Princess's Mansion, the night was still dark.

After returning to his residence in the palace, Shen Huaixu paid close attention to the iron box in the space.

She placed two teacups in front of them, poured a cup of tea, drank it all in one gulp, and then asked after it moistened her throat, "It's strange. Qiao Man knows your weak spot. As long as your mental power goes riot, there's a great chance she can kill you. Why did you bother to get the sand boa?"

Fu Yin also took a sip of the slightly cold tea and answered irrelevantly: "Do you know why she repeatedly reinforced the iron box?"

Shen Huaixu was stunned. "Can't the iron box contain it?"

Fu Yin nodded. "If I'm not mistaken, it should be them. The body of the sand boa can secrete a kind of mucus that is corrosive. They will come out of the box sooner or later. If their existence is not to target me, then..."

He didn't say the rest of the words, but Shen Huaixu already understood. Her expression was very ugly. "As expected of Qiao Man, she is so cruel that she doesn't want us to have an easy life even if she dies."

They have strong reproductive ability, tenacious vitality, and are corrosive.

These few words made Shen Huaixu think of what kind of hell on earth the world would become after the anaconda corroded the iron box.

"Her mind is twisted. Why does she harbor such intense hatred?" Fu Yin seemed to be asking Shen Huaixu, but also himself. He had read many books on psychology, but he still couldn't understand why human love and hate could be so intense.

Shen Huaixu let out a sigh. She didn't know how to answer this question.

Silence flowed between the two of them like a river. After a while, Shen Huaixu asked, "How do we get rid of the sand boa?"
