Seeing Li Chengfeng come forward, the officials who were locked up were even more ashamed.

Just now they dared to rely on their own status to shout, because they have not yet reached the level of knowing the shadow.

They thought some Jiangyang bandit had kidnapped the wrong person, and they wanted to use their official status to scare the other party.

Unexpectedly, Li Chengfeng actually appeared, and revealed Peng Chang's identity in one word.

Now they can't help it.

Although he was innocent, he did not take the initiative to betray the news.

But they have a good relationship with Peng Chang, who knows if they said something that shouldn't be said.

If this is found out, it will be a crime to exterminate the Nine Clans. Reporting others now may still have a chance.

The officials who were still muttering about asking people to let themselves out just now changed the subject.

"As officials of the Tang Dynasty, we should cooperate with His Royal Highness in the investigation."

"Yes! We will try our best to report the details."

"Everyone, don't panic, His Royal Highness will never blame us!"

Li Chengfeng sat on the chair prepared for him by Shadow in the death cell, and looked at these people indifferently.

Now these people are being held in isolation, and the details of their work cannot be contacted outside, and their flaws will definitely be exposed.

Now the entire Chang'an is only allowed to enter but not to exit, even if people outside want to escape, they can't escape.

Moreover, the Peng family's mother and daughter have already started the audit work, and sooner or later all these people can be dug out.

It's just that it's really inappropriate to delay this matter for too long, so he used this prisoner's dilemma to investigate.

For one thing, those officials and businessmen don't know when the other party or other people will betray themselves.

And if you want to spread the information to your associates outside, you must go out as soon as possible.

These two ingenious psychology will make them unable to choose.

Soon Li Chengfeng's method took effect, and the shadow brought an extremely embarrassed young man to Li Chengfeng.

"Your Highness, he claims to know the clue."

The pale young man came to Li Chengfeng and knelt down on the ground.

"Your Highness, I am willing to confess."

"I once saw Yao Tao, the counselor of the Ministry of Officials, helping the Peng family to contact businessmen. I think there must be something wrong with him."

"Usually he has very little contact with Peng Chang, why is he suddenly so enthusiastic."

Li Chengfeng raised his brows slightly after hearing this, it seems that not all of these birthday celebration people are fools.

There are still some people who can clearly distinguish between life and fame which is more important.

"Okay! Next, I will take you to confront those merchants."

"If the information you told me is valuable, then I can write a letter to the emperor to forgive you!"

Li Chengfeng smiled and led the young man out of the prison.

Seeing this scene, the other locked-up people yelled at the shadow guard at the prison door, trying to win life.

The shadow led the man to another prison.

The owner of the firm who delivered to Peng's family in the past few days was locked up here.

"Tell me, who is the boss you mentioned who was in contact with Yao Tao?"

Li Chengfeng led the young man past the prison one by one.

The crisp footsteps fell on the young man's ears, like a death knell leading to hell.

He knew very well that if he couldn't identify the person he was talking about, he might not be able to leave here so easily.

Scanning the figures one after another in the prison, his brain spun rapidly thinking about the scene a few days ago.

Soon a familiar figure fell into his eyes, and the young man stopped with a very happy expression on his face.

"Your Highness, it's him!"

"I saw this man at Yao Tao's house the other day, discussing the delivery of the goods!"

Li Chengfeng nodded slightly, and asked the shadow guard to drag the businessman out for a strict interrogation.

And that young man was also let go, but there will still be shadow guards watching their house all the time.

After doing all this, Li Chengfeng found the shadow again.

"Next, you will interrogate according to the method I just did."

"As long as those officials or businessmen confess, we will immediately find out their relationship."

"After the evidence is conclusive, the relevant people will be arrested immediately."

"Also, don't let go of those who let go, let the shadow guards keep an eye on them at all times!"

Shadow nodded heavily after listening: "This subordinate understands!"

Li Chengfeng's interrogation method is very good and very efficient.

Next should be able to greatly increase their interrogation speed.

Just as he was about to continue to explain, a shadow guard hurried over.

"His Royal Highness, Lord Shadow, Your Majesty has brought along two ministers, Du and Wei!"

Li Chengfeng could only temporarily stop telling the shadow.

"Then I will leave the matter here to you. I will go to meet the emperor and the two ministers first!"

Only then did he leave the dungeon with the two of them and came to the main hall of this stronghold.

"Feng'er, you're here? How's it going? Did you find any clues?" Li Shimin rushed forward eagerly.

No way, he was a little stressed.

Although those officials are not high-ranking officials in Chang'an City, there are too many of them.

If these people are detained for too long, it may cause panic in the ruling and opposition parties, which will be detrimental to the government.

"Father, why are you so impatient?"

"The investigation has only just begun, and it will take some time to dig out all those people."

Li Chengfeng was not in a hurry at all, picked up the hot tea in the hall and took a sip.

At this time, Du Ruhui stepped forward and bowed deeply to Li Chengfeng.

"His Royal Highness, we urgently need an investigation progress to stabilize officials from the ruling and opposition parties."

"Otherwise, if such a large group of officials has been arrested so rashly, I am afraid that the government and the opposition will be thrown into panic!"

Only then did Li Chengfeng put down the teacup in his hand.

"Master Du, would you rather see them panic, or let some people with ulterior motives continue to stay?"

"Now there is a detailed work by Peng Chang."

"If I don't check out all the suspicious people, I'd rather they panic every day!"

As soon as these words came out, Du Ruhui immediately fell silent.

As Li Chengfeng said, the panic of the courtiers is not important at all, the most important thing is to be able to find out the present matter.

"But His Royal Highness, if the imperial city is kept closed, the life of the people in the city may be affected~www.mtlnovel.com~Wei Zheng also raised his own concerns.

As an advising doctor, he naturally hoped that the whole matter would be found out.

However, the planting area in Chang'an City is limited, and most of the daily needs depend on the farmland and vegetable fields on the outskirts of the city.

Moreover, the people on the outskirts of the city also need to come to the city to sell them in exchange for other things.

If the city gate is closed for too long, it will deeply affect the lives of the people.

Only then did Li Chengfeng set a time for them.

"You can rest assured that according to my method, the whole thing will be found out soon."

"I am confident that I will be able to find out all the suspects in three days!"

"However, I need you two to cooperate with me a little bit!"
