The game is bugged unfortunately. You're unable to progress after meeting Ethan in his apartment.
很遗憾，游戏出现了故障。在与埃坦在他的公寓见面后，你无法继续游戏进程。
use the phone to upgrade Ethan to level 5 and go back to sleep for 2 days, after that go back to the slum to continue. At least that’s how I went through…
我把伊森用手機調到五級後 再睡了兩天之後回到貧民窟就可以正常繼續了
