"Aliens" 

The world union didn't deny that these aliens were also somewhat helpful, so the netizens would not question whether the world union just gave out the news one-sidedly. 

The world union even sent out a list of historical figures who turned out to be transmigrators, including their deeds in their entire life and the proof that they were indeed foreign souls. 

The netizens could judge by themselves whether these aliens were more harmful or useful. 

"We know these transmigrators also come to our world by accident, and it's not because they wanted to." 

However, they needed foreign souls to keep the abyss seal, so what to do? 

"We capture a lot of potentially dangerous transmigrators, and we have to use their souls to keep the abyss seal intact for thousands of years." 

"The abyss seal needs a lot of souls, maybe ten souls a year, and one foreign soul with a relatively weak strength can only keep the seal intact for a decade."
