Gu Lingxi planned to check the oil first. She took the oil stains and soil she had taken out at that time and planned to go to the store where they were sold to ask.

She first came to an oil shop.

"Boss! Can you help me find out what kind of oil this is?"

The boss took the soil wrapped in paper from her, put it to the tip of his nose and smelled it.

"Girl, this oil doesn't look like the oil in our store. What we sell is sesame oil. It smells like fat, made from animal fat."

"Does the boss know where to buy this oil?"

"If you walk a little further, there is a store selling this kind of oil at the corner of the street. You can go and ask." The boss pointed in one direction and said.

Gu Lingxi thanked the boss, wrapped the paper in her hand again, and walked towards the shop over there.

"Boss?" This store looks smaller and a bit messy.

After a while, a small man came out and said, "Miss, do you want to buy some gas?"

Gu Lingxi took out the paper bag and handed it to the short boss, "Look, does this oil belong to you?"

The little man took it and smelled it, "I don't know."

Gu Lingxi had no choice but to change her question, "Besides yours, who else in Luo City sells this kind of oil?"

The little man said: "It's gone. All the sesame oil is sold. I'm the only one left."

I don’t know why you are so proud. Don’t you have any idea why others don’t sell it? Gu Lingxi is helpless. Isn’t it because this animal oil is cheap, not profitable, and can’t compare to the fragrance of sesame oil?

"Has your family sold a lot of oil recently?"

The little man fell into deep thought and nodded. Ordinary people bought less and were reluctant to buy more. He remembered that in the first few days, he was very generous and bought a lot of oil at once, and he was very happy to give money.

After hearing his description, Gu Lingxi asked him what that person looked like.

The little man said he couldn't remember clearly, but he remembered that the man was wearing a government uniform.

"He said that the oil for the lamps in the house was running out, so he was ordered to come out to buy it." He said that he was short and could not see the man's face clearly.

Gu Lingxi took the paper bag back and found that it was indeed someone from the government. But why did this person burn the body?

"Thank you, boss." After turning around and leaving, the boss returned behind the counter, trembling, "I've said everything you asked me to say... Please, please, let me go, let me go!"

The cold light of the dagger flashed, and the little boss fell into a pool of blood.

Gu Lingxi planned to have a private discussion with Li Sheng. If someone from the government office was really being taken advantage of, it would be a big or small matter.

In the government office, Li Sheng is watching the case. He has also sent many people to search for clues, but there is still no clue.

Seeing Gu Lingxi coming, he hurriedly stood up and went to greet her.

Gu Lingxi was still dressed in the same clothes today, with her face still covered. Li Sheng was used to it and just asked: "Have you found anything?"

Gu Lingxi looked around, not intending to speak, but whispered: "Walls have ears, let's find a quiet place to talk."

Gu Lingxi brought Li Sheng to Yingchun Pavilion and booked a private room on the third floor. In her opinion, this was the safest place.

It was Li Sheng's first time here. The two of them sat down, and Gu Lingxi said, "There is a mole in your yamen."

Li Sheng paused while drinking tea and said nothing, but he actually thought about it.

The cold room where the corpse was stored was burned. Most people could not enter the government office. She was the only one who could enter this government office. Li Sheng specifically notified the government gatekeeper.

"Actually, you have thought of it, but you just don't want to admit it." Gu Lingxi looked at his reaction and continued: "I found this outside the house that caught fire. I hired someone to identify it. It was animal fat, so the fire was very hot.

It is difficult to destroy because oil has been poured on it.”

"And the person who bought the oil was an officer and soldier in the government office."

"How did you know that?" Li Sheng asked. At that time, he also went to check outside the burned-out cold room and found no oil stains. He might have ignored it.

"I went to find the oil seller, and he can come out and testify." Gu Lingxi took out the paper bag, opened it and put it on the table.

At this time, the waiter knocked on the door and said, "Sir, your food is ready."

The two were silent briefly.

Li Sheng took a deep breath and asked, "What do you need me to do?"

Gu Lingxi tilted her head slightly and said, "Stop the grass and scare the snake!"

She told Li Sheng what to do, and then left the room. She couldn't take off her veil to eat, so it was a good idea to leave.

Li Sheng was not in the mood to eat either. Not long after Gu Lingxi left, he also went downstairs.

"Waiter, check out."

"Okay, sir, the total is - three taels and twenty cents."

Li Sheng was dumbfounded, "So expensive?" If he had known that he would stay longer, he would have at least eaten some food before coming out!

After paying the money, Li Sheng felt extremely pained.
