Cao Zhengchun has controlled the East Factory for many years, although there is Wei Zhongxian on it, but it is not unusual to have these family backgrounds.

But Zhao Yu also understands that this kind of person will generally leave a way back for himself.

Cao Zhengchun must have an unknown secret room to store some top-secret things.

And these things, to a large extent, may have a certain connection with Wei Zhongxian.

The emperor regarded himself as his dagger to balance the hundred officials, and Wei Zhongxian was definitely the number one enemy to face.

Zhao Yu copied Cao Zhengchun's outer house, of course, not for those gold jewels, but to find out what could involve the nine thousand years old!

"My lord, do you want to ask the registrar from outside the house to come in and check?"

Lu Jianxing looked at Zhao Yu and frowned, then stepped forward and asked in a low voice.

"No hurry!"

Zhao Yu shook his head, and then directly crossed the atrium and walked in the direction of the inner hall.

Lu Jianxing and the others followed, while Shen Lian stayed in the front hall, leading people to guard the gold and silver treasures that had been copied out before.

When he came to the inner hall, Zhao Yu stood in the courtyard and watched for a long time, then raised his legs and walked towards Cao Zhengchun's bedroom.

"Fetch the treasure crate!"

After entering the inner hall, Zhao Yu glanced left and right twice, and then stepped forward to take the book down in the middle hall.

I tapped my hand on the back of the book, and there was a dull sound.

Erha took the treasure box, and Zhao Yu took out a gourd with a bottom hole in it.

After sticking the bottom of the gourd to the wall, Zhao Yu's right hand was slightly bent, and his fingers were lightly clasped on the gourd.

Knock knock knock......

On the walls that had been dull before, there were bursts of empty sound at this moment.

"Smash it open!"

Zhao Yu took the gourd, turned to Jin Yichuan and said.

Jin Yichuan took the hammer in the hand of the wrestler, jumped on the main table in person, and slammed it down fiercely according to the place where Zhao Yu pointed out.

Rumble!

As Jin Yichuan's hammer fell, a gap the size of a watermelon was smashed into the wall, and Dongzhu the size of a dragon's eye gushed out.

"No wonder ......"

Jin Yichuan didn't look at the priceless Dongzhu, but picked up the broken wall bricks.

This brick is not much different from other green bricks, the only difference is that this green brick is mixed with cotton.

And between the white walls of the wall and the green bricks, the clay used to fit is also mixed with a lot of cotton.

Therefore, Zhao Yu's previous sound of knocking on the wall was very low. For ordinary people, they will definitely think that this wall is solid.

……

Next, Zhao Yu found a total of seven secret grids in the inner hall, and even the Tiangang Tongzi Gong practiced by Cao Zhengchun was found in the dark grid of the bed.

Seeing that this raid came to an end, but looking at the inner hall that had been copied clean, Zhao Yu always had a strange feeling in his heart.

It seems that there is something important that has been overlooked by myself.

What could it be?

A secret letter involving Wei Zhongxian?

Zhao Yu shook his head slightly, although he didn't know what it was, his feeling told him that it should have nothing to do with Wei Zhongxian.

I searched the inner hall again. After Zhao Yu made sure that there was nothing missing, he walked out of the inner hall suspiciously.

"Go to the front hall and tell Shen Lian to take out a part of the dirty silver and distribute it directly to all the wrestlers in the headquarters of the superintendent!"

Zhao Yu walked out of Cao Zhengchun's dormitory and instructed the herald on the side.

"Obey!"

The little flag officer clenched his fists and received the order, and then went to the outside to give the order.

This kind of thing, when you meet other subordinates, you will definitely be grateful.

But these guys in the headquarters of the Supervision Department have long been numb to Zhao Yu's big hands.

"Jin Yichuan, you go ......"

When Zhao Yugang wanted Jin Yichuan to go to the bookkeeper to check the dirty silver, his eyes looked at the inconspicuous side of the inner hall.

Zhao Yu, who had a flash of inspiration in his mind, suddenly remembered that after he came back from Taiyuan Mansion, he went to Chitose Mansion overnight.

At the beginning, Wei Zhongxian met him again.

Zhao Yu is not a fool, as soon as he entered the side room, Zhao Yu immediately noticed that the magnificent inner hall was just a disguise.

No one wants it, the high-ranking Chitose Lord will live in the inner hall with luxurious decoration, and he will live in the inner hall wing!

Wei Zhongxian is like this, so why is Cao Zhengchun not like this?

"Guard the inner hall, no one is allowed to come in!"

Zhao Yu commanded Erha and Jin Yichuan beside him, and then walked into the inconspicuous wing room in the inner hall alone.

Pushing open the door of the wing, Zhao Yu's nose moved slightly, and then the corners of his mouth sneered.

"Ambergris ......"

At the moment when he pushed on the side door, Zhao Yu smelled a faint aroma.

This is the aroma that lingers in the room, and only burning a spice for a long time will make the aroma linger for such a long time.

The main hall that has just been searched does not have such a long breath.

Zhao Yu walked into the side room, which was somewhat similar to Wei Zhongxian's side hall, except for the bed, there was only one tea bowl and a few futons.

Zhao Yu came to the position of the bed and stretched out his hand to brush the beautifully carved bed.

This whole bed is made of agarwood, which is very valuable in itself, and such a thing will not appear in the wing room.

What made Zhao Yu frown was that he looked at it carefully, but he didn't find any clues.

It's just a bed that's worth a lot of money.

Zhao Yu, who did not give up, continued to inspect the remaining tea cakes, but still found nothing.

"Is it my delusion?"

Zhao Yu looked at the poorly decorated wing room and frowned slightly.

After thinking for a while, Zhao Yu walked out of the wing room and said to Jin Yichuan: "Let all the wrestlers seal the windows and doors of this wing room for me, and there can be no gaps!" ”

"Obey!"

Although Jin Yichuan was a little confused, he still led people to close all the gaps in the doors and windows of the side room.

Zhao Yu turned around and took out a thumb-thick incense from the treasure box, and walked into the side room again.

When Zhao Yu walked into the wing, according to his previous instructions, the wrestlers dipped the door with a cut paper strip and pasted it, completely sealing all the gaps.

Zhao Yu took out the fire fold and lit the incense in his hand.

A wisp of fragrance slowly rose along the lit incense head, and Zhao Yu stared at this wisp of incense.

Suddenly, when the fragrance rose to a height of about two feet, the straight green smoke suddenly fluttered and drifted towards the right.

Zhao Yu looked to the left for the first time, then took the incense burning, and walked slightly to the left, adjusting the position of the incense in his hand as he walked.

Gradually, when Zhao Yu approached the blue brick wall on the side of the tea house, the green smoke emitted by the incense burning in his hand was completely chaotic.

Zhao Yu extinguished the incense in his hand, looked at the bland wall in front of him, and then reached out and knocked twice.

There was still a sound of tamping.

Zhao Yu's right hand moved slightly, and a sharp short sword appeared in his hand.

Following the gap between the blue bricks of the wall, Zhao Yu easily stabbed the short sword into the wall.
