He has been practicing for 500 years, why is he still half immortal and half Buddha?

I looked it up, and you should be asking about the one-armed ape in Monkey King. Journey to the West didn't say who was half immortal and half Buddha. One-armed ape didn't become a Buddha or an immortal because he was too obsessed with fame and fortune. He died in the TV series, but he also became Lohan Khufu.

0 1, I can't let go of fame and fortune. It is said that this one-armed ape, whose predecessor is very prominent, was originally a disciple of Maitreya Buddha and was known as the monkey general. He catches demons and ghosts for the people and is admired by everyone. People's respect for him is like a raging river, like an uncontrollable Yellow River. Arm-linked apes naturally enjoy it, and he thinks it is deserved. Later, the world was affected by drought, and many people suffered greatly.

The once armed ape couldn't bear to see this scene, so he asked Bainiao to distribute all valuable objects in the temple statue built for him by the people to the victims free of charge, so that they could tide over the difficulties. Thanks to the kindness of the arm ape, people finally survived the drought, but because the Monkey King's reputation spread far and wide, the villagers decided to demolish the Monkey General Temple and rebuild it into a great temple.

The one-armed ape values fame and fortune most, and punishes those who want to destroy his golden body. Of course, this incident is just a microcosm of his emphasis on fame and fortune. Maitreya once inspired him, but the one-armed ape didn't understand, and he could only become a half-immortal and half-Buddha.

02. Armed apes will continue. Du Jie's arm ape is one of the powerful villains boss that Tang Priest will meet. Although the arm ape died in the final confrontation with the Monkey King, it also completed its doom and became Lohan Khufu. Before that, in order to kill the Monkey King, he was unscrupulous and insatiable, but after his death, all his obsessions were put down. Later, the demon queen came to see him again (he has become Lohan Khufu), but he is no longer an armless ape.
