Let You Modify the Saber, What the Hell Is a Lightsaber?

Once Shen Yi traveled through time, he awakened the god-level scientific research and military industry system, and started working in the logistics department of the police brigade. The first task is to modify a sharp saber. Old policeman Zhuxing: "Didn't we agree on a saber? Why did I take out a lightsaber!" Shen Yi: "It perfectly meets your requirements. No matter what is in your way, you can melt it. Are you still not satisfied?" The second task is to modify the crossbow. Xi Rongxiang: "How come the power of my family's secret crossbow can be upgraded again?" Shen Yi: "Didn't you say that you can't hit the target accurately? Being able to silently decapitate an enemy thousands of miles away meets your requirements, right?" All the police officers reluctantly signed a letter: "Shen Yi has strong scientific research ability. This weapon perfectly meets my requirements. Please don't modify it next time." Shen Yi: "It sounds like you are not satisfied?" All police officers: "I'm satisfied, but I dare not be dissatisfied." This novel and its characters are purely fictitious.
