Part of the description in the original text: "Mantis now needs to bluff, pretend to be a fierce monster, and use psychological tactics to deal with the enemy in front of him." The grasshopper saw the strange appearance of mantis and didn't know what this strange guy was, so he didn't dare to attack each other easily.

Second, use appearance and voice to threaten each other's psychology.

Some descriptions in the original text: "Mantis spreads its wings extremely, and its wings stand upright like sails", and "it also makes sounds, especially when a poisonous snake exhales". According to these movements and sounds, we can know that mantis is threatening each other with its appearance and voice.

Third, threaten each other with your eyes and make them feel scared.

Some descriptions in the original text: "Stay put, keep an eye on its enemies, keep an eye on its prisoners, and be ready to go into battle at any time", "Mantis immediately turns his head and stays with the locusts", and so on. Mantis hopes that before the battle begins, the enemy in front of him will be at a disadvantage because of fear, so as to achieve the goal of letting him lose without fighting.
