The gate was not closed.

They went straight inside.

The living room was very spacious and plain, with little decoration.

Fu Yichen glanced around and was somewhat surprised; the Gu family's house had indeed been thoroughly robbed.

The valuables in the living room are really gone.

"Nini, I'll go search by myself. You just stay here in the living room and keep watch," Fu Yichen said to Gu Nini.

Gu Nini said, "Yichen, it's okay, I can do it too. It'll be faster with one more person, since they have quite a few rooms here."

Fu Yichen said, "But this is too dangerous. If he has a weapon, he could easily hurt you. So, you should just stay in the living room!"

"Nini, listen to me, don't be stubborn!"

Seeing Fu Yichen's expression, Gu Nini finally nodded.

After Fu Yichen persuaded Gu Nini, he began to inspect the area starting from the first floor.

He checked very quickly.

A few minutes later, the entire first floor had been searched.

Gu Weiguo was not found.

As Gu Weiguo headed up to the second floor, Gu Nini followed.

She joined in the search.

When they arrived at Grandma Gu's room, there was still no one hiding there.

Just then.

Gu Nini pointed to the ground: "Yichen, look, there's some soil we brought back from outside."

Fu Yichen looked closely and found that there really was a small piece of soil that had been brought back from outside, which had fallen to the ground.

"It seems that Gu Weiguo really did come back, and he might even be hiding in his house."

Gu Nini suddenly said, "Yichen, do you think the Gu family might have some kind of secret mechanism or something? After all, the Gu family are capitalists, and they have so much wealth. They must have some kind of underground secret room to hide things, right?"

Fu Yichen trembled slightly, then said, "That's actually quite possible!"

"How about we look for any government agencies or institutions?"

Gu Nini nodded, and then they began to explore Gu's grandmother's room.

"Huh? Yichen, this candle is fake, it's fixed in place." Gu Nini came to the wall and moved one of the candles on the wall.

Fu Yichen came to Gu Nini's side and moved the candle, discovering that it could be turned.

He listened carefully to the sound of it turning, then looked at Gu Nini: "Nini, it seems you were right. The Gu family really does have a hidden mechanism. This is clearly the control for the switch."

Gu Nini immediately asked excitedly, "Then can we solve this mechanism?"

Fu Yichen said, "This might be a bit difficult; we can only say we'll try."

"If all else fails, we'll have to resort to brute force."

Gu Nini's gaze swept in another direction, and then she said, "Hey, Yichen, there's another candle over there. Go try it and see if that's also controlled by a mechanism."

"Could the Gu family have set up two controls for this mechanism?"

Is it that complicated?

Fu Yichen also saw the other candle. He went over and tried it, and found that it was the same as the previous one.

He looked at Gu Nini and said, "Nini, it seems you guessed right. This candle is also a switch. If there are two control switches, then cracking it will be even more difficult."

"It seems that brute force is the only way out!"
