After a while, Xiao Ding suddenly remembered the Old Ghost's warning. He hurriedly opened his eyes and said to Liu Feixu: "Oh, I forgot to tell you one thing. We don't need to reveal our identities. The other side is already targeting us. Liu Feixu, think of a way, we should seize this opportunity to open a gap in the people who are watching us. "Alright, I'll leave it to you."

With that, Xiao Ding shamelessly closed his eyes.

Liu Feixu rolled her eyes at him.

This was an important clue.

During the day, Liu Feixu kept an eye out for movements in her surroundings and behind him, to see if anyone was following him. However, she did not find anyone following her.

Liu Feixu guessed that these people must have some clever methods to avoid her eyes. There was only one point left, these people had followed them for too long, and had already exceeded the distance from where she could watch.

Liu Feixu didn't know how Xiao Ding found out. But she knew that Xiao Ding would not joke around on this matter. Since Xiao Ding said that someone was following him, then someone must be following him.

Initially, when she was at a loss, Liu Feixu had thought of revealing her identity on purpose, luring out the people who were following him, and then going along with the flow to find out who was the mastermind behind the kidnapping of the scientist. Now the other side had given them a chance. Then she had to make good use of it.

The best method would be to follow them from the back, but right now, they only had two people. Naturally, their identity as a couple who came to visit would be exposed. They would definitely attract the other party's attention and turn into dogs instead of tigers instead of tigers. Instead, they would let the other party know that they had discovered them.

This method would not work.

Notify Captain Xie and the others to follow them. However, they still did not know where they were. Perhaps they had already arrived at this city. In order to prevent the other party from noticing, the three groups had flown to different cities, and only one group had flown directly to this city. The rest of them had landed on the ground and then rushed to this city.

Liu Feixu thought that since she had already discovered them, she would have to follow them back tomorrow. Because scientists have been missing for a long time, the longer it lasts, the more likely it is that something will happen.

Liu Feixu thought for a while, but still couldn't think of a good method. Suddenly she thought, Why don't we follow them back to the hotel? The men saw them returning to the hotel and thought they would not go out again.

Thinking about it, Liu Feixu said: "Xiao Ding, how about this, tomorrow we should return to the hotel earlier and send one of our men to fight them. Even if they have to keep an eye on us, they will send someone back to report the situation. "

Xiao Ding opened his eyes slightly and nodded. "En, good, after we return to the hotel, I will go back with them. You can go back to rest."

"Why you?" Liu Feixu felt that she was being looked down upon.

"Xiao Ding glanced at Liu Feixu:" Because I was the one who noticed it. I'm afraid you've lost it. "

When Xiao Ding said this, Liu Feixu had nothing to say. Indeed, she did not even know that someone was following him, proving that the other party was more skilled at following him.

In truth, Xiao Ding did not realise that someone was following him. If not for Old Ghost's reminder, he would not have known about this. Even more so, Liu Feixu had such a consciousness, paying attention to her surroundings to see what was happening, yet he did not even have such a consciousness.

However, Xiao Ding had the Old Ghost, a cheating divine tool, so he was not afraid of losing the other party. Of course, if Xiao Ding had this awareness, he would release spirit energy to observe his surroundings and not lose the opponent.

The night passed silently. On the second day, Xiao Ding and Liu Feixu were like a couple again as they strolled around the city.

A few times, Liu Feixu asked Xiao Ding: "Where is the stalker?"

Xiao Ding didn't mind at all as he said lightly, "Don't look around everywhere, I don't want to alert the enemy."

Xiao Ding's words were also logical. Liu Feixu could only suppress her curiosity and did not inquire further.

However, they returned to the hotel an hour earlier than yesterday.

Upon entering the hotel, Liu Feixu said, "Xiao Ding, hurry up and get out of here. Otherwise, if they leave, all the previous work will be for naught."

Xiao Ding said calmly, "Don't worry, they won't be able to escape my grasp. Let's go up to the room first. In case they were suspicious. And I have to change my clothes. "

After going up to the room, Xiao Ding changed into a new set of clothes, channeling spirit energy to slightly change his temperament.

Liu Feixu was shocked: "Xiao Ding, I never thought that you would actually have this kind of ability. You only changed into a new set of clothes, and you don't look like the you before."

Xiao Ding could not believe it, but he thought to himself: I used my spirit force to change my temperament, this is a job made by techniques, ordinary people cannot do it.

Liu Feixu urged Xiao Ding to go quickly. Xiao Ding went out and went downstairs. Actually, Xiao Ding had already made the Old Ghost watch the two stalkers downstairs.

Perhaps because it was still early, the two stalkers did not leave and were still staring at the entrance of the hotel.

Xiao Ding stayed nearby for a while before he saw one of them leave. Xiao Ding immediately followed him.

After walking not too far, that person walked to a car, got in the car, and drove away quickly.

Xiao Ding was stunned, he did not have a car. Even though he could probably keep up with them by circulating his spirit energy, it would cause quite a sensation if someone saw him in broad daylight.

Old Ghost said, "It's fine, I have already made a secret mark on both of them, so I left some of my spiritual energy on them.

Xiao Ding stood still and closed his eyes slightly. After he carefully experienced the situation, he discovered that there was indeed a car a few kilometers away that he had to follow. He then took large strides and followed.

In this way, when he lost sight of him, he would once again stop and carefully experience his surroundings. After that, he would once again lock onto his target.

After more than an hour, Xiao Ding arrived in front of a fifty story building. He felt his pursuer enter the building, which was now heading for the underground elevator.

After locking his target, Xiao Ding headed inside the building. But he went through several elevators, none of them going down. At most, they would only be on the second floor. His target had now reached the seventh floor and stopped.

Xiao Ding quickly went to the security room on the second floor and asked where the elevator to the seventh floor lead to. The security guard replied in a daze, "This building only has a negative second floor. It doesn't have a negative seventh floor."

Xiao Ding clearly felt that the target he was following was already several tens of meters deep underground;

Suddenly, Xiao Ding thought that this was a rather secretive place, and ordinary people wouldn't know about this.

He thanked her and went out. He entered the basement level two from the side and searched around until he finally found the elevator in a remote corner. However, there were two muscular men standing in front of the elevator, wearing black suits and black sunglasses, looking exactly like gangsters.

Xiao Ding was not confident that he could enter the elevator without the two of them reacting. If he alarmed these two, then he might as well not follow them.

After a while, Xiao Ding thought of Old Ghost, and immediately asked: "Old Ghost, can you go deeper into the Seventh Floor?"

Old Ghost said, "No, not unless we go down from the elevator. Because it's completely sealed, except for the elevator. Even if I go down from the elevator, I will definitely alert the two people at the door. "

Xiao Ding sighed dejectedly. Even so, it had still alarmed them. If he didn't want to alarm them, he would have to move them away.

Xiao Ding had actually wanted to call Liu Feixu back, so that he could lead the two of them away. Just as they were about to leave, they suddenly thought of something. In fact, the Old Ghost was the most suitable candidate.

Xiao Ding then said: "Old Ghost, please cooperate with me for a while and create some noise, luring the two of them away, I will take the elevator down."

Old Ghost agreed as he channeled his spirit energy and gave the carriage a push. The car moved quickly. The two men at the elevator door were surprised to see the car move.

Taking the chance, Xiao Ding rushed to the elevator door, opened it, and entered. Sure enough, this elevator was specially designed to go down. He pressed the button for the seventh floor. The elevator descended.

At this moment, the two of them heard the sound of the elevator. They quickly turned around and saw that the elevator door had strangely closed.

"Did you see anyone pass by?" one of them asked, staring at his companion.

"No, I didn't see anyone pass by." The other had a puzzled look on his face.

"But, the elevator door was obviously opened just now." the man asked at first.

The two of them walked to the elevator door and found that the elevator was moving down. The number on the floor quickly became minus seven.

Someone got into the elevator and went down.

One of them quickly spoke into the microphone beside his face, "Section Chief, someone has come down to the seventh floor."

The seventh floor was a very secretive place. Letting the two of them stand guard here was to prevent unrelated personnel from going down.

When the people on the seventh floor heard these words, they immediately tensed up. The two people on top were actually unable to stop them. One could see how powerful he was. Section Chief, who was in charge of security, hastily gathered four to five security guards and rushed to the elevator's entrance.

When Xiao Ding heard the footsteps outside, he knew that he had alarmed them, so he quickly used his Spirit Qi to jump up, and stuck close to the top of the elevator. He knew that most people would hear someone coming down in the elevator, and would first look at the person standing at the elevator.

After the elevator stopped, the doors automatically opened. However, there was no one inside. Section Chief immediately asked: "I didn't see anyone come down, did you see wrongly?"

"Can't see anyone?" The two of them looked at each other in astonishment. Actually, they didn't see any shadow of her. When they turned around, they only saw the elevator door closing.

Maybe the elevator was out of order. They guessed.

"Did you really see anyone get into the elevator?" The people below asked again.

"Section Chief, no, we just saw the elevator door close and found out that the elevator was descending, so …"

"Aren't you standing in front of the elevator? Doesn't anyone know if there's anyone entering the elevator? "

"Section Chief, we saw a car moving on its own, so we went over to take a look. We heard the elevator door opening, and when we turned around, we saw the elevator door closing, so we thought someone had entered the elevator."

"
