Preparations.

You Xi Wang and his team prepared for the raid. The teams got familiar with the weapons and gadgets they were provided with while You Xi Wang was absorbing every piece of knowledge he got from the library of Elfheim. He wanted to learn about the tech and then use it for himself. 

Two days passed, You Xi Wang called Fenny over to the library. He spoke, "Bro, the phasor guns they developed can be detected by the lab system. You need to bypass the detection code. If the system can detect the weapons, then the raid will fail." 

Fenny spoke, "These people are quiet slick. Leaving the backdoor entrance in the weapons. Tsk tsk, sneaky bugs. How do I bypass this code?" 

You Xi Wang took out a storage cube. The elves used a cube shaped device to store the data in their computers. He spoke, "This is something I wrote. It will bypass the detection without disturbing the performance of the weapon."
