Zhang Tie didn't imagine that his grandpa's health could deteriorate so fast.
Zhang Tie remembered that it was over 2 years ago when he saw his grandpa last time before he was going to leave Youzhou Province for the Western Theater of Operations at the Xuanyuan command. In his second chakra rotating ceremony, Zhang Haitian had started to cough as he became humpbacked with a crutch in hand. Before he left Youzhou Province for the Western Theater of Operations, he paid a special visit to his grandpa. Zhang Haitian didn't look bad then. Zhang Tie even left some tips and secret medicines to him. Therefore, he was outrightly shocked by such a piece of news.
It was Zhang Lin who came here to notice Zhang Tie. Zhang Lin was Zhang Su's father, Zhang Tie's eldest uncle, the eldest son of the eldest son of Zhang Haitian and the principal of Zhang family's old mansion.
