Li Xiulan nodded and said, "Yes, the police came and took the old woman's body away. My husband hid everything he found on the old woman."

I scolded him for doing that. The old woman clearly said that she would give us some money as a reward for exchanging a gold bar!

But he said the gold on the old woman must not have been obtained honestly, otherwise why wouldn't she dare to exchange it for gold bars herself?

He suspected that the old woman was either a fugitive or someone of questionable character who had run away with her child.

At that time, many people with questionable backgrounds either jumped into the river or were arrested.

He originally intended to sell the two children, since boys could fetch a good price.

But I felt guilty, so I told my husband that since we don't have any boys, we could adopt these two children and raise them as our own sons, which would also help continue the family line.

I persuaded my husband, and he agreed to keep the two children.

A few years later, when regulations weren't so strict, my husband secretly exchanged a gold bar and sold our current house.

Li Xiyue asked, "Is there nothing else besides the gold lock and gold bars? There should be other letters or something!"

Li Xiulan nodded and said, "Yes, I've hidden all those letters. But I feel their identities are really questionable. If these letters are discovered by others, things will probably be even more difficult for Lao San!"

"It's better to just say he was found. What else can you investigate? The investigation will only reveal that the old woman led them out of hiding. His background will be cleaner that way!"

Li Xiyue said, "I'm afraid you're oversimplifying things. If you can't find out his true identity, it'll be easier to pin an even more terrible identity on him and kill him! Let me see the letter first."

Li Xiulan's gaze fell on the wall of her own house. She roughly determined the location, then took out a pair of scissors and poked at the wall.

He poked off a large chunk of white plaster from the wall, revealing the red brick underneath.

Li Xiulan struggled to pull out a red brick and took out an oil paper package from it.

The oil paper package contained only one letter.

She handed the letter to Li Xiyue and said, "Besides the gold lock and gold bars, this is the only thing I have. Take a look at what's written on this letter. I don't know many characters, and I can't understand this cursive writing."

Li Xiyue opened the envelope and carefully read the words inside.

Mibao stared wide-eyed at the contents.

It exclaimed in surprise, "Holy crap, so the Mu brothers are descendants of the foreign tycoon Mu Jinguo!"

Mu Jinguo has businesses in several overseas countries, making him one of the wealthiest individuals in the past decade or so.

Li Xiyue and Mi Bao said, "Back then, when his whole family ran away, one of his sons happened to be visiting his classmate's hometown with his classmates, and missed the opportunity to run away with the whole family."

The son stayed in China. Obviously, the situation was very unfavorable for him. Fortunately, when he returned to the old house, he found letters left to him by his grandfather and parents, as well as gold bars and the family business in China.

At that time, family businesses could be converted into shares for public-private partnerships. I think he was doing quite well then.

Mi Bao said, "But after the company had been operating together for more than ten years, the situation changed. The letter said that Mu Cangnan's biological parents had died, and that old woman was his family's nanny. She ran away with the two children."

Li Xiulan stared intently at Li Xiyue, and asked nervously, "What did the letter say? Are his family spies?"

My husband suspects his family are spies, which is why that old woman fled with her two children!

Li Xiyue said, "No, his family isn't spies. They're just wealthy businessmen. His grandfather has a large business overseas. His parents died more than 20 years ago. That woman was their old housekeeper, and she ran away with them."

Li Xiulan nodded. "So his family were wealthy merchants. Does he still have any relatives?"

Li Xiyue said, "As far as I know, his wealthy grandfather has a large business empire overseas, and he's still alive. But his whole family is definitely not spies! Keep this letter with me, and I'll find a way to save Mu Cangnan!"

Li Xiulan said, "Good child, the third son is counting on you. I don't know anything. Go quickly and tell the inspectors that he's not a spy!"

Li Xiyue said, "Don't worry, I'll find a way to save him. You should get some rest."

She calmed Li Xiulan down and left the Mu family with the letter.

She had Mibao set up a spatial portal, through which she traveled directly to the Investigation Bureau.

Clearly, the Investigation Bureau is different from other departments. It is a four-story building with guards and patrols both inside and outside the courtyard.

Even during the day, walking past the door gives one a sense of solemnity and gloom.

Li Xiyue's spatial passage is set directly in the corridor.

She emerged from the spatial passage and stood at the corner of the corridor.

She peeked her little head out into the corridor.

The corridor was quiet. Even when someone walked by, their steps were hurried. And despite having so many people on the four floors, no one could be heard talking.

Mibao said in the space, "I don't like this kind of place, it's too quiet here!"

"Isn't the point of work to joke around and have fun? Working in a place like this will make anyone develop depression sooner or later!"

Li Xiyue said, "This department is different from the others. Let's find out where Mu Cangnan is first."

Her X-ray vision allowed her to see through every room on the fourth floor, but Mu Cangnan was not among them.

Taking advantage of the fact that no one was in the corridor, she quietly slipped up to the third floor to look for it.

Fortunately, there are no cameras anywhere in this era, so she is not afraid of being seen.

When she reached the second floor, she finally found Mu Cangnan in an interrogation room.

One side of the interrogation room had a long table and a long chair, while the other side had only one chair, where Mu Cangnan sat.

Mu Cangnan stood ramrod straight, his solemn face upright and unyielding, cold and icy.

The people sitting opposite him whispered and discussed it among themselves.

The person in the lead was the inspector captain who went to arrest Mu Cangnan.

Sitting next to the head of the inspection team was the section chief of the investigation bureau.

The head of the investigation bureau tapped his finger on the table and said to Mu Cangnan, "Honestly confess your problems. How much of our classified information did you leak to foreign spies?"

Mu Cangnan said, "I have never leaked any confidential documents!"

Clearly, his words did not satisfy the person sitting opposite him!

The head of the investigation bureau sneered and said, "Mu Cangnan, we already have evidence! We're asking you this as an opportunity to confess and seek leniency!"

Don't be so stubborn! Don't keep making the same mistake! Do you really think we don't know about your overseas connections?!

Mu Cangnan said, "I have no overseas connections, and I have never contacted any foreign spies!"
