Du You slowly stood up and looked at the endless void: "I have to set out again, it might take a few days this time, you both wait for me at home." Du You said to Xi Qianxue and Li Mengyao beside him.
That's right, Du You has been guarding this world for quite some time now. So it's impossible for him to always be in the same place; over the years, this place has almost become his home. Or rather, the time Du You spent here over the years has surpassed the time he spent at the academy, and even other places.
Hence later on, Du You brought his family over as well. After all, the world he's guarding also hosts an eighth-tier world; although it doesn't belong to him, mobilizing this world's power is quite easy.
Considering that Du You is now a ninth-tier sage, he commands significant authority on Earth. When he needs this world to mobilize resources and assist him, this world naturally wouldn't just go through the motions.
