There was a knock on the door.

"Who?" Jing An asked weakly with two dark circles under his eyes. Since he was separated from Karn that day, he has once again devoted himself to his studies without distraction, and the dark circles under his eyes have come out, and as for the progress of his studies, it is a little slow!

"I'm Dr. Li, I'm here for a review," a suave voice replied outside the door.

Jing An's spirits perked up, and he immediately became like a living dragon, the reason why he is like this, the problem lies with Doctor Li!

Everyone, don't get me wrong, Dr. Li is not a beautiful woman with a full body, nor is he a handsome guy who is so handsome that he is scummy, by the way, Jing An's sexual orientation is normal.

On his first day in Jing'an, Dr. Li, who claimed to be surnamed Li, came to check on him. Jing An saw at that time that he was wearing a mask that could almost be fake, although this mask could make all kinds of vivid expressions, but the fake was fake, how could it escape Jing An's fiery eyes?

If it was in the previous life, Jing An would definitely not have found it. The reason why he can see through it at a glance now has a lot to do with his ultimate stealth of ascetic cultivation - his ultimate stealth has just started, and he can simulate a big living person into a lifeless stake, so that even the birds can't find it.

To put it simply, he is now an expert who is fake and real, and in front of an expert like him, a mask wants to deceive him? Pipe dream!

Jing An immediately smeared the prepared things on his hands, and after wiping them, he opened the door and said, "Doctor Li, you have come for a follow-up check-up, I feel that my body is very good, great!" ”

"You're too young to understand the cunning of some diseases!" Dr. Li pushed the glasses on the bridge of his nose and said gently, "They will hide themselves well, slowly eroding your body, and it will be too late when they are discovered." Finding them is my job! ”

"You're the one who hides yourself well!" Jing An silently added in his heart, and then, he pulled Doctor Li's sleeve with a frightened expression, and said anxiously, "Then you can give me a check-up, I feel uncomfortable at the thought that I may have a cunning illness in my body, am I hopeless?" ”

"Don't worry," Dr. Li pointed to Jing An's bed and said, "You lie flat on it, let your uncle check your body to know if you have any problems!" ”

"Uncle check-up?" This sentence made Jing An have a bad association, he thought of the strange Shu millet in his previous life, they like to find all kinds of excuses to check Lori's body! Could this Dr. Li also have this hobby?

Jing An felt a chill and secretly decided that if Dr. Li was "hairy" for a while, then he would definitely give him a lesson that he would never forget!

Fortunately, Dr. Li is not that kind of person, and he took his leave after taking some blood from Jing'an, saying that he was going back to study it, and it is unknown whether it is true or not!

Jing An also left the room shortly after Dr. Li left. He closed his eyes for a while, and then walked into a corridor on the second floor, and at the end of the corridor there was a figure that had just disappeared, it was Doctor Li!

That's right, he's stalking Dr. Lee.

According to Jing An's observations, this Doctor Li is not only proficient in disguise, but also agile, and most importantly, Jing An feels the breath of the same kind in his body! Based on this information, he limited Dr. Lee's true profession to being between a killer and a thief, or both.

How could Jing An ignore such a dangerous person lurking on the airship?

Whether it was out of consideration for his own safety, or out of gratitude to Wu Xiaolan for helping her clear the hidden dangers, he had to know why this Doctor Li was lurking on the airship and what his purpose was!

As for how to do this, there are many ways, but with his current strength, the only way to do it is to track!

Now that he already knows that Dr. Li may be a thief, then using the ordinary tracking method to track him is obviously suspected of having an axe, but fortunately, Jing An also has a more efficient, safe and fast tracking method, which he named perception tracking!

As the name suggests, this method uses perception to track the target.

Perception, everyone has it, the difference is only in the strength and weakness, of course, this is only the vast majority of people's understanding of perception. However, in Jing An's view, the intensity of perception is important, but the sensitivity of perception should not be underestimated, and the ultimate stealth he practiced is a ready-made case - the principle of this stealth is to use the sensitivity of his own perception to deceive other people's six senses, so as to achieve the goal of making himself disappear in all directions in the eyes of the target!

Suffice it to say, his perception may not be the strongest, but his perception sensitivity must be the highest. And his perceptual tracking method was born based on this.

If you want to stalk someone in this way, you first need to prepare the casting materials.

Jing An first grinded the moonstone into a very fine, fine powder - in perception, this white and transparent powder would produce a slight vibration. This vibration can only be detected by a person with a high degree of perceptual sensitivity. He didn't believe that Dr. Lee's perceptual sensitivity was the same as his own.

And so it was, as evidenced by the fact that Dr. Lee didn't feel anything when he smeared the powder on Dr. Lee's body!

At this point, the entire tracking method has been completed - no matter where Dr. Li goes, Jing An can accurately find him with the vibration of the moonstone, this efficient, safe, and fast tracking method has thrown those tracking methods that rely on eyes and noses to smell more than a hundred streets!

I'm afraid Dr. Li never dreamed that he would be followed so easily.

Jing An relied on his self-created tracking method, easily hanging behind Dr. Li, voyeurizing to his heart's content, oh no, it was to monitor his every move! The only pity is that I didn't get any useful information after following all day.

"This Doctor Li is really cautious, he hasn't leaked out at all throughout the day" Jing An touched his chin thoughtfully, Doctor Li is usually so cautious in his life, he must be an old thief, this kind of old thief is not something he can deal with, do you want to tell Wu Xiaolan?

He thought about it, and decided not to tell it first, even if he wanted to tell it, at least he had to find out the purpose of Dr. Li's lurking, otherwise it would not be good to startle the snake.

After making up his mind, he began to pick up the teaching materials of all evils and began the learning journey of destroying the three views!

After tracking for five days in a row, there was no gain, and Jing An even planned to tell Wu Xiaolan about it directly, so that she would have a headache, but she didn't expect that in the middle of the night, Doctor Li didn't rest, and went straight to the top floor as soon as he went out.

Seeing this, Jing An immediately changed into a night suit—well, a gray cloak, actually—and quietly followed.

Just as he was about to reach the top, he unexpectedly ran into a man - the bald Karn!
