How to enter the 4th floor of the hotel ruins in Battlefield King biochemical mode?

It’s very easy. Anyone who has played CS knows how to jump. The principle is similar, but the battlefield is still more difficult to jump. Then jump from the lower left corner of the house (just a little above it). Be careful not to hit the highest pillar. When jumping up, press the right button and the squat button at the same time. You may get stuck when you go up, but don't panic. Just try moving left and right. If you jump on it, you'll be invincible hahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahaha! ! ! (Just be careful of the mother body and the bombs thrown up) I wish you good luck!
