After the slaves were raised, they all turned over and became masters

Yu Ze traveled to the fairy world named 'God' and got a 'Slave Cultivation System'.
After finally cultivating the slaves into talents, then...he was stabbed in the back by one of them.
With the help of the system, Yu Ze returned to his former hometown, Biao Xing.
I thought I would spend a period of high school and college life in this way, and then live a beautiful and happy life.
However, shortly after traveling back, he found that his own world and the world of "God" had an indescribable connection, and many traversers appeared one after another.
People are enthusiastically discussing those powerful names that have only been heard in rumors in the world of God, and they are even more yearning for them.
Yu Ze was dumbfounded.
What made him even more dumbfounded was that he actually saw the adopted slave appear on the TV news: "It is understood that Ji Ningshuang, the patriarch of Guiyi Sect, has confirmed that he will come to Chaoxing in three days. A successful exchange..."
"The demon queen Su Dieying signed a treaty with the Northern Alliance of the Western Continent, and the two sides have reached a good consensus on cooperation in the future."
"Holy Court Church Pope Kailin will descend on Rixing today..."
Looking at the magical news reports, Yu Ze fell into deep thought for a long time.
Bad, they seem to turn over and call the shots.
