Really where did he pop out from

Madam Zhang shrank her neck, she didn't want to retreat but Lin Zhi, this sister in law of hers wasn't easy to deal with. Ever since Lin Che got injured and started to recuperate at home, Lin Zhi had become more bold and daring. She would often complain about Lin Che taking the opportunity, that she gave him by giving up her life. Lin Zhi also continued to emphasise how Lin Che didn't care about all her sacrifices and made trouble by fighting with the refuges despite knowing that he couldn't win against them and now that his hand was broken, he was staying at home doing almost nothing like a disabled person.
