Draw the Sword Hundreds of Millions of Times and Kill the Ancestor of the Demon Sect at the Beginning

Traveling to a fantasy world where demons are raging, Ye Xuan, who has mediocre qualifications and is unable to practice, becomes a woodcutter of the Tiandao Sect. Fortunately, the god-level sword-drawing system is activated. As long as you draw the sword, you can become stronger. "Draw your sword a thousand times, and you will be rewarded with a full level of sword drawing skills!" "Draw the sword ten thousand times, and the reward will be 100 million!" "Draw the sword 100,000 times, and you will be rewarded with the magic sword Abi Dao reaching the level of three swords!" "..." In this way, Ye Xuan grew up silently in the Tiandao Sect. He drew his sword thousands of times in three years. Three years later, the Demon Sect besieged the Tiandao Sect, and no one in the Tiandao Sect could defeat it. Just when everyone was gone, a ray of sword light came out from the back mountain and killed the ancestor of the Demon Sect... This novel and its characters are purely fictitious.
