Wasted Sword God: Sign a Contract First at the Beginning

Lin Xiaobei wore it. When he woke up, he was in a mass grave. His identity was that of a waste slave in the Black Stone Mine, number 3704 - he was at the bottom of the spiritual world and could not absorb any spiritual energy. Others rely on hard work, the system, and grandpa to achieve time travel. He is different. In his previous life, he was the sales leader of a real estate group and won three consecutive sales in the country. So he was not in a hurry to practice sword practice. He settles the accounts first. He does the purification of waste mineral veins; he changes it to a contract system for slaves to cook in a big pot; but the supervisor refuses to accept it? Sign a betting agreement and get slapped in the face. He turned the mine into a group, changed the sect into a joint-stock system, and engaged in direct sales, mortgages, and price discrimination for the elixir magic weapon... What is the meaning of the sword? When others realize it, he signs it. Before drawing the sword, "This business is a loss"; after drawing the sword, "the deal is done"; after sheathing the sword, "If the price is higher next time, I won't have to draw the sword." Later, the entire world of cultivators remembered this sentence—— Don't mess with Lin Xiaobei. What he wants is not your life, but your signature.
