Wei Yunlan and others were brought back to the Military Intelligence Department solely to cooperate with the investigation of the case, and had no direct relationship with the appearance of the Northern Barbarian spies.

At most, it can provide some minor clues.

I thought that the Military Intelligence Department would at most send an ordinary officer to question them.

But after waiting for half an hour, it turned out that the left deputy director whom they had met before in the forest farm came to see them in person.

And each person is asked separately.

First, he asked Qiu Yuehua and Tu You, and found out that this hunting in the forest was indeed organized by Qiu Yuehua on a whim during a chat with several young ladies at the flower-viewing banquet. As for Tu You, before the encounter with the Northern Barbarian spies, he was sent out of the forest by Wei Yunlan to seek help, and he did not have any contact with the Northern Barbarian spies alone, nor did he find many clues.

Then he let the two of them leave first and called Wei Yunlan in.

"Miss Wei, Northern Barbarian spies are appearing in the territory of Dayong and causing great trouble. This is related to the stability of the border. I hope you can answer the following questions truthfully."

Lord Lu, who was sitting at the top, looked serious, and there was scrutiny in his eyes as he looked over.

"Excuse me, sir." Wei Yunlan looked calm and not afraid.

As the saying goes, a man of integrity fears no slander. Whether it is her or the Wei family, when it comes to being loyal to Dayong, they will not tolerate any fault.

"Miss Wei, may I ask, when you found Miss Liang's whereabouts and heard the unusual movement in the forest, why did you suggest that Miss Tu leave the forest to get help, while you rushed to the place where the noise came from first?"

Lord Lu had been closely observing Wei Yunlan's expression. Seeing that she looked the same, he paused and continued, "As far as I know, Miss Tu is from a military family and is skilled in martial arts. It would be safer for her to go and help Miss Huang defend against the enemy, wouldn't it?"

Lord Lu’s questioning was very rigorous.

Wei Yunlan did not have any resistance to being interrogated. On the contrary, she felt that a place like the Military Intelligence Department needed someone like Lord Lu who asked strict questions and did not miss any details.

Lord Lu asked seriously, so she answered seriously: "There are two reasons."

"First, I had just arrived at Beiguan and was not as familiar with the place as Miss Tu. Also, I had another person on my horse at the time, and Miss Tu turned around and rushed to the outside of the forest farm, so we were faster."

"Secondly, Miss Tu is the daughter of the deputy commander of the Northern Army. If she comes forward, she will be taken seriously, and the forest farm will be able to dispatch personnel to support her more quickly."

Lord Lu listened carefully without saying a word, but now he seemed to agree with her more. Obviously, what Wei Yunlan said was right. If she had been the one who went out to dispatch support, she would have had to spend a lot of time explaining, and she would not have been able to gather people as quickly as Tu You did.

"As for Lord Lu's last question."

Wei Yunlan continued, "Miss Tu has been practicing martial arts since she was young. Her martial arts skills are definitely better than mine. Even though I have never fought with Miss Tu, I can guess this. But I am not completely powerless and useless. Lord Lu should have known that not long ago, my family and I just walked a journey of more than 3,000 miles to the north in exile..."

Lord Lu had a calm expression on his face. He nodded when he heard this and motioned Wei Yunlan to continue.

"Nowadays, disasters are rampant everywhere. The journey is difficult. Without some skills to save our lives, we won't be able to reach the North Gate alive." As he spoke, Wei Yunlan took out two tightly rolled balls from his sleeves, handed them to the officer standing by, and asked him to present them to Lord Lu.

"What is this?" Lord Lu picked up a round ball and looked at it carefully. It seemed to be wrapped in a layer of ordinary kudzu.

"There is a kind of wild grass in the folk that can make people's skin itch when ground into powder. It is jokingly called itchy grass. The ball in your hand is made of itchy grass and charcoal ash. It is more effective than ordinary itchy grass."

"It's wrapped in a layer of ramie cloth on the outside. If you throw it out and hit something, the cloth will fall apart, and the powder inside will spill out and cause unbearable itching on the skin..."

"This is one of my trump cards, and that's why I rushed over to help."

Wei Yunlan guessed that even if he didn't say it, Lord Lu would ask him what happened to the scratches on Chunyan and the Northern Barbarian spy.

As expected, Lord Lu showed a look of realization on his face, and he drew two lines on the case file with the brush in his hand, and the doubt in his eyes faded a little.

"I have one last question."

"Excuse me, sir."

"Miss Wei, as far as I know, Miss Liang entered the forest farm to harm you. I wonder if you can tell me what old grudges you have with Miss Liang?"

"Love and hatred." Wei Yunlan explained further: "Miss Liang was deceived by the sweet words of Chen Feng, the son of Jinyang Marquis, and has admired him for a long time. Because I was married to Chen Feng, she regarded me as a thorn in her side. But she blamed the wrong person. Chen Feng and I have divorced, and we had no friendship before the divorce. Chen Feng's sweetheart was kept in captivity by him for many years, and now he is brought into the mansion as a concubine. She looks a bit like Miss Liang."

Lord Lu: “…”

The officers: “…”

The hall suddenly fell silent. No one had expected that while trying a case, they could hear the secrets of the residences of the nobles in the capital!

"That's what happened anyway. Miss Liang blamed the wrong person." Wei Yunlan recounted the confusing account in one breath, without any intention of leaving any fig leaf for the Marquis of Jinyang's Mansion.

She knew that all the case files that were examined would be submitted back to the capital in the future.

Even if Emperor Xiaoming did not read it himself, the officials in the Ministry of War would have seen it. Naturally, no one would spread rumors when it comes to military secrets, but there was no need to keep such insignificant matters secret.

By then, these things about the Marquis of Jinyang's Mansion will most likely spread throughout the capital, and Chen Feng will surely become a laughing stock among the nobles in the capital. If Xue Linglong knew about this, she would probably make a fuss and disturb the peace of the Marquis of Jinyang's Mansion.

In this regard, Wei Yunlan only wanted to say two words, "You deserve it."

This is just an appetizer. It is not yet time to settle accounts with them and the Second Prince.

Let them jump around for a few more days. The higher they jump, the harder they will fall!

Now, let them fight each other and torture each other in the Marquis' Mansion!

After hearing all this love, hate and vengeance, even the knowledgeable Military Intelligence Department could not help but remain silent.

"Ahem." After a moment, everyone who had been listening with great interest came back to their senses.

Lord Lu cleared his throat and said, "Miss Wei, I have no other questions. Thank you for your help in stopping the Northern Barbarian spies. I will have someone escort you out."

"No need to trouble you, sir." Wei Yunlan politely declined the Military Intelligence Department's offer to send someone to escort him.

After exiting the gate of the Military Intelligence Department, I saw Qiu Yuehua and Tu You who had been waiting for a long time in front of the door.

After waiting in front of the door for a while, Huang Yuling also came out with some people.

"This new Lord Lu is really serious about his work. I think he will be able to get something out of the Northern Barbarian spies."

"It's a pity that we can't know the details..."

After expressing their feelings along the way, the four of them parted ways between the southern and northern halves of the city.

Wei Yunlan returned to Jingping Lane and had just comforted her worried family. Not long after returning to the house, she saw Zou Yun climbing in from the back window.

"Miss Wei, the master has instructed that the information about the North Gate does not need to be concealed from you."

"The result of today's forest farm incident has been revealed, so I'd like to let you know."
