Old man Mo Yuan still has a habit, even if he doesn't leave, he will check every book collection place in the whole building every day, even if no one has ever come in, he will always do this.
As for the order of inspection, there is no order. Sometimes it starts from the first floor and goes up layer by layer, sometimes it starts from the top floor and goes down slowly.
At other times, it may start from the middle, but he doesn't know whether to go up first or down first. Just now I started from the fourth floor, and then checked the fifth floor by the way, and then slowly checked down.
It's a pity that Bai Yuzhe didn't know this, otherwise he would have taken advantage of it.
But Bai Yuzhe also knew that if he wanted to go out, he had to find out some habits of this old man. Therefore, after Bai Yuzhe put away the paper, he walked out of the library on the fourth floor cautiously, without caring about any damage, and looked down.
But now that Mo Yuan has entered the third floor, the collection of books inside is much larger, Bai Yuzhe doesn't know it, so he is taking advantage of himself to be invisible, so he can only bite the bullet and walk down slowly, not letting himself send out any words. Sound and movement.
This is indeed possible. The reason why he was so nervous before was because the distance between the two sides was too close. Bai Yuzhe was afraid that something unexpected would happen, plus the relationship between the paper.
It took about a minute or so for Bai Yuzhe to walk from the fourth floor to the third floor. When he was about to reach the gate and wanted to take a look inside, Mo Yuan suddenly came out from inside, almost face to face with Bai Yuzhe. face to face.
Bai Yuzhe was taken aback immediately. Fortunately, his determination was firm, and he didn't show any panic at this time. He still controlled the invisibility array and his breath well, and then took a step back calmly.
Mo Yuan walked in front of him, and the distance between the two sides was only about 30 centimeters. Fortunately, today's stealth array is much stronger than the original one after modification.
In the past, he would also block some of his breath, but it was not perfect, at least if the distance was too close to a master like Mo Yuan. Whether it is from breathing or heartbeat, it may be noticed.
And the current stealth array completely isolates all of these. It's just that there are not many stealth arrays after this transformation, and they are all in the hands of Bai Yuzhe's closest people, as well as a few people at the top of Tongtian Tower.
Mo Yuan walked past Bai Yuzhe, and Bai Yuzhe could even slightly feel his breath. With a sense of twilight, it is obvious that time is running out, judging by Bai Yuzhe's medical skills, it will be about ten years at most.
In addition, there was a particularly gloomy aura that made Bai Yuzhe's hairs stand on his head for a while.
However, Mo Yuan still didn't find Bai Yuzhe, and continued to walk down. Bai Yuzhe just stood there, watching him walk into the second floor, still checking.
"Opportunity!" Bai Yuzhe's heart suddenly moved. When the old man checked the third floor just now, it took about three minutes. The second floor obviously has more books, and the time will definitely not be less than three minutes.
No more hesitation, Bai Yuzhe followed immediately, but his speed was slower, for fear of making any noise and being noticed.
When he reached the second floor, Mo Yuan inside had already begun to check, Bai Yuzhe didn't even look at it, and continued to walk down.
