Have You Ever Seen Such a Low System?

He graduated from the School of Mechanical Engineering with a major in Mechanical Engineering and Automation. He has been practicing martial arts since he was a child, and he is a good swordsman and is the hope of the whole village. He finally won the first place in swordsmanship in a national competition, and was known as the "Sword Master" in the world. There were eight people in the competition. He is a time traveler with his own system: mechanical engineering. When he faced his fiancée and teammates, he said shamelessly: "What's wrong with touching me? I didn't even say anything!" When he faced the monsters all over the mountains and plains, he had the courage to say, "Even if there are thousands of people, I will go there." When he was using Gatling to shoot at the overwhelming monsters, he couldn't help but exclaimed, "This... Is actually a tower defense game?" Who is he? That's right! He is our protagonist-Zhang Yi.
