[Book Traversing System] the Plot Does Not Follow the Routine! What to Do?

The reborn black-faced apprentice x the funny and arrogant time travel master Shen Yunli felt that he was probably the most unlucky person among all the people who became masters through books. On the first day he came here, he was slapped to death by his blackened apprentice. I thought everything was over like this, but I never thought that he would be resurrected again and time would go back to the first day here. After dying several times, Shen Yunli finally understood that he could only change his cannon fodder's fate by dying again and again. What's even more tragic is that he not only wants to save his own life, but also the life of his blackened apprentice. That's all, who made him his disciple? Anyway, I got used to it. However, why is his apprentice looking at him more and more strangely recently?
