Metal SlugUpgrade flowBeast controlFunny Guo Xiujin traveled through time and became the old man in the game Metal Slug. S-level genius Su Wanqing summoned someone to go abroad to cultivate gold, but found that the other person was just an eighty-year-old F-level old man wearing big green pants. She gave up the contract on the spot and allowed Guoxiu Jin to lose its coordinates and disappear. Everyone is laughing. Only the F-class girl Tang Yala, whose summoning failed, stepped forward and cut the hemp rope around the old man's wrist. The rescue contract is established! Tang Yala: "I'm sorry, I seem to have contracted an old man who can hang up at any time..." Guo Xiujin: "Gan! I'm only twenty!" Facing a powerful enemy, Guo Xiujin took out his weapon H-bomb, "HEAVY MACHINE GUN!" Rub the turtle Qigong with your hands to give the earth a center. Since then, Blue Star has had a pair of characters with unusual painting styles. If someone else cultivates the spirit, he can become younger by upgrading. He can also pull weapons and tanks from his pants. Solve the fear of insufficient firepower!
