After Lu Chengfeng eliminated the suspicion of Qi Juetang in his mind, he felt that the case was full of doubts:

First of all, where does this nux vomica come from?

Secondly, if there is a strange poison in hand, how did the murderer inject it?

Again, how does the murderer ensure that no one in the house can escape?

Then, why did he disguise himself as Qi Juetang and hang all thirty-two corpses? Why did he go to such great lengths to hang them in such a regular manner?

Finally, there is the most confusing question for everyone: how did the murderer escape?

Lu Chengfeng hurriedly found the study room and found pen, ink, paper and inkstone, trying to write down the five major doubts in his mind in black and white to avoid confusion. In this way, all that was left was to solve the problems one by one.

Before he started writing, he realized that his hands were already frozen! It was indeed freezing cold! He raised his eyes and looked at the sky outside the window.

The sky is getting late and the night is deep. The courtyard of Jiang Mansion has long been covered in silver, which has become the best disguise for this tragedy of annihilation of the family.

"You stay, while everyone else goes to clear the snow in the courtyard!" Lu Chengfeng ordered.

If we don't sweep away this thick white coat, how can we see the sin and filth hidden underneath?

After saying that, Lu Chengfeng rubbed his hands and put his frozen palms on the oil lamp to bake them.

I don't know if it was because the weather was so cold that his limbs were numb from the cold, but he accidentally knocked over the oil lamp. All the lamp oil splashed onto the white paper on the table, and the flames started to burn quickly along with the spilled lamp oil! In an instant,

In a short time, he burned all the thick white paper on the case!

It was too late but not too late, Lu Chengfeng smashed a pot of flowers on the shelf beside the desk into the flames. After a while, a wisp of green smoke emerged from under the pile of broken flower pots and rubble.

The fierce flames were extinguished by the soil.

However, when the flames flickered just now, Lu Chengfeng seemed to see some strange patterns protruding on the white paper that was lit, but before he could see clearly, the paper was completely burned by the fierce fire.

"Did you see that paper just now?" Lu Chengfeng asked the soldier beside him.

It's a pity that the incident happened too suddenly, and the soldier obviously hasn't recovered yet.

Feng had no choice but to remove the broken flower pots covering it, and then carefully push aside the remaining flowers, gravel and soil one by one, carefully observing whether there were any unburned shreds of paper. However, he only found some black powder.

It should be the ashes after the stack of paper was burned.

"Look on the bookshelf, in the cupboard, or in the box. Is there any white paper like that just now?" He cheered up and became alert.

"Reporting to His Majesty the Emperor, there is another pile here!" As expected, the soldiers dug out some white paper of the same size, texture, and thickness from the cabinet.

Lu Chengfeng took out a piece of paper and put it on the oil lamp to bake. After a few seconds, a blue wave-like symbol appeared on the white paper. Every two waves overlapped but were different.

The incompatibility is like a handful of small blue crosses tattooed on the four corners of the paper. Among the small crosses, there is also a small blue dot, which looks like a small fish that cannot close its mouth!

"Your Highness, this seems to be the secret code of the Cao Gang!" Fu Bing took the piece of paper, looked at it carefully, and said with his eyebrows raised.

"Caogang! So, the Jiang family is a member of the Caogang? The Caogang has people all over the world, but its foundation is in Beijing. What does it have to do with Nanli?" Lu Chengfeng felt that the case became more complicated.

Confused, "Come! Let's search the study together again!"

After rummaging through boxes and cabinets, Lu Chengfeng already knew the background and identity of the Jiang family. On the surface, this Jiang family man was doing business with the Western Regions, Nanli and other places, and was doing business as a tea-horse and salt merchant. In fact, secretly, he was doing digging.

It is immoral to collect treasures and ancient artifacts from people's ancestral graves.

No wonder the Jiang family, as a little-known little tea horse salt merchant, could afford to live in such a deep compound! The reason why the wall of the courtyard was built so high must be to hide it from others so that they can do some shameful things in the house!

And those antique treasures stolen from the tombs were all traded through the Caobang! This fish pattern plain paper must be the secret code for his transaction with the Caobang!

Lu Chengfeng carefully checked Jiang Mansion's account books. In the thick stacks of account books, the cumulative transaction amount recorded reached hundreds of thousands of gold! However, the clues were cut off when they reached Caobang!

"I have just returned to the Imperial City, and I am not familiar with everything in the capital. Tell me, in addition to escorting food, is the Caobang in charge of other affairs?" Lu Chengfeng was at this moment.

Already frowning.

"Reporting to His Majesty the Emperor, the Caobang is responsible for transporting grain and escorting official salt. I guess that's why I got in touch with the Jiang family!" Fu Bing replied seriously.

"It's possible! Let me ask you again, are there any other industries involved? For example, the black market!" Lu Chengfeng looked at Nafu Bing with sharp eyes.

"Reporting to Your Majesty the Emperor, the Cao Gang has always been like this. It is more than just a black market! In this capital city, as long as there is profit, they will get involved! Over the years, they have relied on the big tree behind them, but

We have gained a lot of benefits! Our Jingzhao Yin Mansion can only turn a blind eye, as long as we don’t go too far and don’t make trouble in front of the emperor!”

The soldier actually knelt on the ground, not even daring to raise his head, and continued to explain solemnly.

"It's not that the villain intends to hide it! The villain is a soldier, but he really dare not take the initiative to mention it! Isn't this a matter of not opening and lifting the pot!"

"What did you say? Who is the big tree behind Caobang? Can you tell me?" Lu Chengfeng asked eagerly.

"I don't dare to say this..." The soldier not only lowered his head to the ground, but also hesitated.

"There are only you and me in the house at this time. God knows that you know that I know! You can rest assured and come and listen to me." Lu Chengfeng knelt down, lowered his voice, and leaned into Nafu Bing's ear mysteriously.

promised.

"I only know that the leader of the Cao Gang, Ma Rulong, has a close relationship with the prime minister's son, Tang Bourne..." The soldier whispered uneasily, his eyes turning around and scanning the surroundings for fear of being overheard.

"You mean, the Cao Gang's backers are the prime minister and the prince!" Lu Chengfeng was shocked and shouted in surprise.

"I, I didn't say anything! I didn't say anything!" The soldier covered his mouth and ran out of the study in a panic.

Forget it, if I ask again, he probably won’t dare to say anything!

The nervous and fearful attitude of the government soldiers made Lu Chengfeng even more sure of his own judgment. Combined with the previous Tianxiang Tower incident, he had already fought with Tang Bo. It seemed that the prince and the prime minister manipulated the Cao Gang to amass money and allowed them to do evil.
