Don't Bully the Old and Poor, Why Are You Crying When I Become the God of War?

Yang Xuan traveled through time and became the first generation martial artist of the Cataclysm Gaowu, and lived to be 160 years old. But because he had no children, his energy and blood were withered, and he was treated as a soft persimmon by his descendants. The coffin was missed, the main attic was occupied, and even the raised granddaughter was forced to marry. Just when he was frustrated, the system woke up. "Ten thousand times the increase in cultivation": Others practice hard for a year, but I retreat for an hour! "10,000-Fold increase in elixir refining": Ordinary elixir? I directly purify it beyond human cognition! "Amplification of understanding ten thousand times": The Martial God Space is opened, and all martial arts are at your fingertips! Then, everyone in the Yang family discovered in horror. The old man whose body was half buried in the ground regained his energy and blood, straightened his waist, and slashed out with his sword, causing the mountain to collapse and the ground to crack! Everyone in the Yang family collapsed.
