This is a seminal film from the 70s. It depicts HuangYu the god of war fighting against aliens. Guanyu's GuangDao (which is his halberd) is a large blade that he can wield it in full circles to fight against multiple space aliens. At one point, the aliens summons a net that drops down above him. GY (which I will use to denote GuanYu as it is his initials) is so powerful that he just burst straight out of those nets. The aliens are stunned but continues to fight on. Near the end, the alien leader attempts to use a ray gun that GY skillfully battles against with his trusty melee weapon. The scale of this fight is phenominally large that both GY and the aliens tower above the skyscrappers in this dense urban enviroment that they engage the battle in.
