刀枪不入那是悟空
[dāo qiāng bù rù nèi shì wù kōng]
Invulnerable - That's Wukong! The name references Sun Wukong (from 'Journey to the West') known for superhuman capabilities like magic power and invulnerability, symbolically meaning a person so strong that bullets and blades can do no harm, often used in a context of boasting courage or defenselessness.
