"Do you want to use Tang Haochen's nose to chase him along the smell?" Xiaobai suddenly reacted, flapped his wings and flew up, and grabbed Si Yufan's collar: "What are you waiting for? It's time for someone to run away in a while!"

"Don't worry."

Si Yufan pressed Xiaobai and a curved curve appeared on the corner of his mouth: "Let him run for a while first, and when he relaxes his vigilance and reveals his true face, we will chase him again."

He narrowed his eyes slightly, stared at the direction where the mysterious man left, and snorted coldly: "I don't believe that he can hide the smell completely!"

After a while, Si Yufan called Tangtang, left and followed the smell and chased into the private room of a restaurant in the center of the city.

Si Yufan kicked open the door of the box, but unexpectedly it was empty inside, and his face suddenly became cloudy.

"Damn it! Why is there no one?"

"The taste...the taste is gone at this point." Tangtang squatted on the ground with grievance, his head deep into his arms, and raised his hand to draw circles on the ground.

"This... has he disappeared out of thin air?" Si Yufan suddenly remembered something, leaned down and shook Tangtang, and asked impatiently: "Who else is there except the mysterious man?"

Tangtang looked up and sniffed: "And... there is Cao Qiyan... Cao Wenhuan... Zhu Chengzhu... Wei Zhengping..."

"You idiot! I told you to chase after me quickly, but you won't listen!" Xiaobai jumped over Si Yufan's head, pecking him hard, venting his dissatisfaction.

Si Yufan shook his hand and drove Xiaobai away. Now he needs to think carefully, but Xiaobai made him unable to calm down.

"My benefactor, is it you?"

At this moment, a familiar voice sounded behind him. Si Yufan looked back and saw the woman who was stopped by the soldiers when he entered the city, standing behind him, looking at him with joy.

"Why are you here?" Si Yufan couldn't help but wonder.

"This is the store opened by my relatives, and I'll make a living here."

The woman carefully took out a handful of spirit stone from her arms, counted it carefully several times, and then handed it to Si Yufan, and smiled and said, "My benefactor, this was what you gave to us that day. Now I have work to support myself and my children, so I just take this opportunity to return it to you."

Si Yufan took the spirit stone, weighed it a few times, and then stuffed it to the woman, asking in a deep voice: "You should know the situation in this private room, right? I bought this news with the spirit stone."

"You are my benefactor, how can you receive your spirit stone?"

The woman pushed the spirit stone back to Si Yufan, but Si Yufan refused to accept it. The woman couldn't resist and had to carefully take it back to the original place.

"Then I will tell you all the things I know. This is the best private room in the store, and it has always been reserved for the city lord and Cao Wei. I saw the eldest lady of the Cao family come in just now, and you came not long after."

"Have there anyone else in and out?" Si Yufan frowned.

The woman shook her head.

Si Yufan told the woman a few more words, asking her to go to the Wei family to find her at any time if there is any situation, so she took Tangtang out of the restaurant.

"It is basically certain now that the mysterious man is between the three parties." Si Yufan lowered his head and walked towards the Cao family, thinking for a long time and said in his heart.

Xiaobai looked up at him with a hesitant expression: "But I have checked before and there are no medals on them."

"If you don't have one, it doesn't mean they are not members of the organization!"

Si Yufan rubbed the tears mole on the corner of his eyes: "According to the style of a mysterious man doing things, he is very likely to have put the medal in the space bag, so we can't find it at all."

While talking, several people passed by a dim alley. Seeing the pedestrians hurriedly coming in and out with hoods, Si Yufan hurriedly took out two robes, put them on himself and Tangtang, and walked inward.

"Aren't you trying to find out the identity of the mysterious person? What are you doing in the black market?" Xiaobai asked in confusion.

Si Yufan looked at the passing people with his light while walking, and explained in his heart: "Zhu Da said that the medicine man's medicine was bought here, but why did the mysterious man do this?"

"Do they want to test the medicine?"

Si Yufan nodded slightly: "I'm the same guess as well."

Xiaobai pondered for a moment and slowly shook his head: "These three families have people who are for their dispatch, why bother to do this?"

Si Yufan recalled the scenes of these two encounters with the mysterious man in his mind and analyzed:

"The two consecutive temptations were all approached by disguising themselves as others, which means that he did not want to reveal his true identity, so he would never use the people around him to experiment.

But if this is the case, there will be insufficient manpower. If you want to continue the experiment, you must sell pharmacist potions to the outside world.

And this is the best place for him to sell..."

Before he finished speaking, Tangtang suddenly pulled his arm: "The smell of fake Cao Qiyan...the smell comes out again!"

"Quick! Chase me!"

Several people ran all the way and came to the corner of the street. Tangtang pointed to the person sitting alone in the corner. The man was holding a bottle of pharmacy and talking to the buyer opposite him about something.

He noticed that Si Yufan and others were walking towards him, and hurriedly stood up, closed the stall and hurriedly left the place.

Si Yufan's steps were fading and appeared in front of him like a ghost, reaching out to grab his left wrist.

The man was unable to defend himself and was left with five blood marks on his wrist by Si Yufan. However, before Si Yufan could continue to move, the man's figure swayed into the crowd and disappeared directly.

Under the guidance of Tangtang's smell tracking, several people chased outside the black market, but there were too many people on the street and they could not tell who was the mysterious person.

"So cunning!" Xiaobai said angrily.

"It doesn't matter!"

Si Yufan's lips raised slightly: "At least after we go back, we can try to eliminate it from the Cao family first."

...

When they returned to the Cao family, Cao Qiyan and his daughter rushed back. Si Yufan hurried over, stopped them, and told them about the situation in the black market.

The father and daughter rolled up their sleeves. Seeing that there was no trace of them, Si Yufan couldn't help but breathe a breath: "I was almost driven crazy by that guy today. I offended the two of them before, and I hope I'll forgive me."

Cao Wenhuan waved his hand and said in a deep voice: "He plans to attack Qiyan. He is my enemy. If you have any clues, my Cao family will definitely help you!"

"I really want to ask for help."

Si Yufan pondered for a moment and said slowly: "I suspect that this person is either Lord Zhu or Wei Zhengping. He is just because he has never had the opportunity to meet them, so he cannot verify it."

"This is a bit difficult to deal with. If you go directly to them, they will never cooperate with you." Cao Wenhuan scratched his head, unable to think of a suitable solution.

"I have an offer."

Cao Qiyan cleared his throat and told his thoughts: "It's time to eat, so why don't my father think of an excuse and invite those two to have a simple meal at home. Everything will naturally come to light!"

"This idea is great!"

Si Yufan slapped his chest hard, and his little face turned red with excitement: "It just happened that yesterday's incident was over. Why not just call the two of them on the grounds that they asked Lord Zhu to help and ease the atmosphere of the two families.

Then I will take the opportunity to investigate and I don’t believe he can still hide it!”

Seeing that Cao Qiyan's method was approved, Cao Wenhuan hurriedly arranged it.

Si Yufan looked at the busy Cao family and couldn't help but smile.
