One reason was that the State of Wei's foundation hadn't been destroyed, unlike Great Shun's, so relocating it would damage it.
The other was because the State of Wei had less than 10,000 people remaining while everyone else had died. There was not too much point in taking these people away.
If he couldn't relocate the State of Wei, he would have to leave people to guard it. As such, it would be best to leave the people here. It was also a pity that Zhao Fu couldn't take away the corpses of the soldiers with high grades, as the State of Wei now belonged to Great Qin. Refining their corpses instead of giving them a proper burial wouldn't look too good.
However, there was a person and three corpses that Zhao Fu had to take. The person was a round-faced young man who had served as Wei Xin's bodyguard. He was called Gou Bian, and he was a famed General of the State of Wei who was SS grade. The three corpses were all historical Generals of the State of Wei.
