Guanyin Sent Me to the Western God Realm as an Undercover Agent.

Lei Xun was originally a carp in the Guanyin Lotus Pond. He practiced Buddhism for 500 years before becoming an immortal. He was preparing to lie in peace but accidentally entered the realm and came to the Western Realm. He went through a lot of things at the beginning, but when he was ready to return to the Eastern Immortal Realm, he unexpectedly received an order from the Great Immortal Guanyin to work as an undercover agent in the Western Immortal Realm. Reluctantly, Lei Xun's "undercover" plan was officially launched. He monitored the enemy's situation, collected intelligence, checked undercover agents, was exposed, faced life and death, and survived from desperate situations, leading to the secrets between the Western God Realm and the Eastern Immortal Realm...
