Become an Ancestor: Increase the Invincibility Time by Ten Seconds Every Day

Lin Feng traveled through time and became the dying ancestor of the Qingyun Sect, an unpopular sect. His body is decaying and his life span is about to end. Seeing that the enemy sect is about to kill him from the top of the mountain and destroy his whole family. At the critical moment, the [Immortal Invincibility System] awakens! The invincibility time is increased by 10 seconds every day, which can be accumulated if not used! A lottery can be held every 10 days! As a result, an ancestor with a strange painting style appeared in Qingyun Sect. The enemy sword master called for formation? Lin Feng stretched out a finger: "It only takes three seconds to kill you." Three seconds later, the sword master fell. Lin Feng coughed up blood (actually he was pretending): "I... Am getting old after all." The sect leader cried bitterly: "Ancestor, please stop burning your life for the sect!" Lin Feng fell into deep thought as he looked at the tens of thousands of seconds of invincibility accumulated in the system space and the warehouse full of magical elixirs. Don't try to persuade me, I can really fight for another ten thousand years!
