This is the most fun level. You can add a "guard" to the stairs, defeat the big-headed doll at the door, and then knock off the referee's expression. He will take an enemy. If an enemy tries to throw the ball in the distance, jump up and avoid it. The enemy who tackles the ball, just hit it from behind after tackling the ball. Going forward, I met the little BOSS, which is a server. When he serves, he can't hurt him by hitting back. He can only hit the ball back when serving. Go back and forth a few times and win. BOSS***3 kinds of attack methods, launching chest missiles, raking nails and attacking the ground. The BOSS's style of play is very simple. Just stand a little further and hit the missile back. In addition, you need to pay attention to the ground attack. You must jump up before the boss's foot hits the ground, or you will be shocked to a hard value. The rake is a close attack, and the long-range attack occupation can be completely ignored. The national treasure mode is too difficult, that is, there are too many bullets in the small BOSS, and it is easy to be knocked down as long as you jump at the wrong time.
