Don't shoot, I'm just a Honkai up master!

After time travel, the penniless Su Yu chose to use the system to become a Thunderbolt Upmaster in order to survive.
In "The Last Lesson", Jizi burns herself to light the way forward for her students;
"Salmon Burns Forever", Qiyana inherited Ji Zi's will and fought for all the good things in the world;
"Thus Spoke Apocalypse", everyone witnessed the real side of this man for the first time, making everyone love and hate him;
Just when everyone thought these were just animations, a floating island that seemed to be the headquarters of Destiny suddenly fell down above the European Mediterranean Sea; Killed a white-haired wielder, clamoring to judge the world!
That night, the Heavenly Sword Bureau, the supernatural incident response department, broke into Su Yu's home.
In order to prevent violent conflicts, Su Yu could only stop Kiyana who was about to pull out the Great Sword of Fire, Bronya who was about to activate the Star of Eden, and Alicia who had just taken out the flying flowers of the past.
Then Su Yu said helplessly to the staff of the Heavenly Sword Bureau.
"Don't get excited, as you can see, I'm just an ordinary up master"
