Chapter 1336: thrilling

Old man Mo Yuan still has a habit. Even if he doesn't leave, he will check every book collection in the entire 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 one after another. Sometimes it starts from the top floor and slowly goes down.
Sometimes, it may start from the middle, and as to whether to go up or go down first, then he himself is not clear. Just now, I started from the fourth floor, and then checked the fifth floor by the way, and then slowly went down to check.
It's a pity that Bai Yuzhe didn't know this, otherwise he would have the opportunity to take advantage of it.
But Bai Yuzhe also knew that if he wanted to go out, he had to figure out some of the old man's habits. Therefore, after Bai Yuzhe put away the paper, he cautiously walked out of the four-story bookstore, ignoring any damage, and looked down.
But now Mo Yuan has entered the third floor. The amount of books in it is much larger. Bai Yuzhe doesn’t know, so he takes himself to be invisible, so he can only bite the bullet and walk down slowly, not allowing himself to emit anything. Sound and movement.
This can indeed be done. The reason why they were so nervous before was because the distance between the two parties was too close. Bai Yuzhe was afraid that some accident would happen, plus the paper relationship.
It took about a minute or more before Bai Yuzhe walked from the fourth floor to the third floor. When he was about to reach the gate and wanted to look inside, Mo Yuan suddenly walked out of it, almost facing Bai Yuzhe. Opposite.
Bai Yuzhe was taken aback at once, but fortunately, his mind was indeed firm. At this time, he didn't show any panic. He still controlled the invisible formation and his breath well, and then took a step back calmly.
Mo Yuan passed in front of him, and the distance between the two sides was only about 30 centimeters. Fortunately, the current stealth formation is much stronger than the original one after the transformation.
In the past, it would also block some of its own breath, but it was not so perfect. At the very least, facing a master like Mo Yuan, the distance is too close. Whether it is from breathing or heartbeat, it can be detected.
And the current stealth formation completely isolated all these. It's just that there are not many invisible formations after this transformation, and they are all in the hands of the closest person to Bai Yuzhe himself, as well as the few people at the top of the Tongtian Tower.
Mo Yuan passed in front of Bai Yuzhe, and Bai Yuzhe could even slightly feel the breath of him. With a twilight, obviously 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 atmosphere that made Bai Yuzhe's hair stand upside down for a while.
However, Mo Yuan still did not find Bai Yuzhe, and continued to walk down. Bai Yuzhe stood just like this, 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 probably took about three minutes. The second floor will obviously have more books, and the time will definitely not be less than three minutes.
No longer hesitating, Bai Yuzhe immediately followed, but his speed was slower, for fear of making some movement to be 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.
