The supporting character's harem is very normal - Chapter 486: Am I a Villain Boss?

The Master of the Tai Yi Sect, Patriarch Xu Yi shattered the void, causing the entire sect to travel through to the interstellar era.

On the deserted planet, the disciples discover a new world:

The eldest senior brother, who specialized in forging, fell in love with mech building. The second senior brother found that alchemy could also be manufactured on an assembly line; The third senior brother fell in love with live broadcasting and was addicted to the Internet; The old Master Xu Yi cracked his whip and urged the disciples, ‘This world is so rich in spiritual energy, how dare you not cultivate properly?’

In the Immortal Cultivation Realm, Junior Sister Sa Sa, who had no spiritual root and powerful spiritual sea, was finally no longer distressed by her inability to cultivate: ‘Mech’s are really powerful!’
Double standard — Xu Yi: … Study it. Isn’t it just mechs, Sa Sa should have one too.

A little bumpkin from a deserted star came to the Federation’s First Academy.

Sa Sa, ‘Wow, the internet is awesome! Mech’s are awesome! Technology is awesome!’
‘You don’t need to cultivate to become strong in the interstellar world, I really love love love it.’

Students from prominent and powerful backgrounds scoffed, ‘Where did the bumpkin come from? Is there something wrong with the admissions system?’
They had no idea that the anchor who exploded onto the internet had a great relationship with the little bumpkin.

Sa Sa: ‘Third Senior Brother is secretly on the internet again!’

The elixir that the little bumpkin usually took and hard to find, the spirit sea boosting pills with no side effects, was actually worth a thousand bucks?

Sa Sa, ‘Second Senior Brother makes the most delicious sweet pills!’

The mech that the little bumpkin casually pulled out was actually the upgraded version of the mech that everyone was fighting over?!

Sa Sa, ‘Eldest Senior Brother will definitely save the best for me!’

The whole planet was abuzz: ‘What kind of divine institution was Tai Yi? How do I get in? Waiting online for a reply!’
