Journey to the West: I have a check-in system against the sky

Zuo Xiaodao traveled through the world of Journey to the West and became an unpopular land. He accidentally obtained a check-in system against the sky and merged with the beginningless Hunyuan Dao
In the fetus, he suddenly realized the Daluo mantra, severely injured the golden-winged roc eagle at the beginning, fought against Monkey King, and became the biggest anomaly in the three realms and six realms.
He becomes stronger when he signs in, becomes a saint with one breath, and crosses the Three Realms!
