I Can Instantly Cast 100 Million Sword Energy

Three years ago, an ever-increasing counting panel suddenly appeared on Gu Xuan's retina. Like a stopwatch, a number increases every second. It did not increase again until the number reached 100,000,000 a month ago. Gu Xuan, who was full of expectations, waited and waited, but nothing happened. He was still the same ordinary person. It wasn't until the day he arrived at the Tower of Heaven that he finally knew that the number of 100 million represented his innate skill, the amount of sword energy stored in the [God's Sword Box]! At the beginning, with 100 million sword energy in hand, Gu Xuan transformed into a humanoid Gatling and outputted wildly. In the battlefield of all realms, he was fearfully called by the enemies: Namo Gatling·Yi Sword Emperor! (Dear donors, please collect and recommend, otherwise I won't be polite if I have this blue-lighting Namo Gatling in my old aunt's hand, da da da da da da da da~(*╹▽╹*)~
