My Cultivation of Immortality Shouldn't Be Like This!

[Single female protagonist] [No system] When others travel through time, the three-piece set of System, Grandpa, and Tianlinggen is full. I traveled through time, got distracted in class and was punished by standing still, tempered weapons and almost blew myself up, and was chased by a she-wolf when I went out. Others are flying with swords, and their fairy aura is floating. Why is this broken sword chasing after me? After finally picking up a palm-sized sword spirit, the first thing he said was, "You are too weak and don't deserve me to wake up early." Others accept talented teammates, but in my team there is a dragster and a team-destroying guy. Okay, let's make do, and we can still break up. Just when I thought I was unlucky enough, that aloof girl with white hair and red eyes, who only said "Don't block the road" when we met, kicked my enemy away, walked out with his head, and told me with blood all over her body. "Master asked me to take care of you." Then he left without looking back. ... Who is your master? You should make it clear! This is a story about an ordinary time traveler running around like crazy, occasionally fighting back, and being targeted by a big boss for no apparent reason. Although it is very tiring, it seems... Quite interesting.
