Weird Cultivation: I am the Yellow-skinned Taoist Master

The first year of cultivating immortals. Chen Huangpi had a copper-skin and iron-boned body, and was invulnerable to water and fire. Black smoke billowed with every move he made. The master said that was spiritual energy. The second year of cultivating immortals. Chen Huangpi felt extremely itchy, and hundreds of evil eyes broke free from his flesh and blood, emitting malice unscrupulously. The master said that this was called supernatural power. After a hundred years of cultivating immortals, Chen Huangpi's eighteen feet were rooted in the dark earth, and his nine heads reached the sky. When he opened his bloody mouth, he could hear obscure and evil sounds. He called himself the Taoist Master Huangpi. Chen Huangpi looked up and saw his master sitting in the ninth heaven, his whole body was dark blue, and countless gods, immortals and Buddhas were struggling and wailing in his shadow. "Master, are we really cultivating immortals?"
