The eldest son's family was so daring to take out such evidence so brazenly. They were probably afraid and anxious that people would know what they had done, that was why they were so eager to legitimize and publicize it in front of so many people.
Huo Xuanzhou's face was also filled with killing intent as he stared at Huo Xuanze and Huo Xuancong, who were in front of him. He wished he could kill them, even though he didn't want to think bad of people who were blood related to him. Even though Sixth Uncle said that Second Uncle was involved in Grandfather's hospitalization due to his illness, he still harbored the last bit of hope that it wasn't him.
However, this document clearly told him that their grandfather's illness was definitely caused by his second uncle's anger. With their grandfather's personality, how is it possible that he would give all of the Huo family's assets to his eldest son's family? They were really shameless and daring.
