You can't delve into the story of time travel, or you will fall into it. Let's just say he has logic. Next, answer questions.
1 500 years ago may be a vague concept, that is, about 500 years ago, or 500 years before the exact time. But no matter when, the Supreme Treasure is gone, there is no reincarnation of the Supreme Treasure, only the Great Sage. Where is the Supreme Treasure? Five hundred years ago, she died by the sword of 30 Niang. The cow died 500 years ago, so there will be no later 30-year-old Niang and the old cow looking for the reincarnation of Tang Priest, and there will be no two women fighting with the old cow, so there will be no time to travel and rewrite all the history. As for what to change, the eighth ring road won the first place in the final exam, and tofu beauty is the answer.
2. Sunset samurai and unknown chivalrous women, I tend to explain in the story of "Big Talk 2online". They are nobody, but the love between the Great Sage and Xia Zi has become a shell, just an empty shell, destined to entangle in this world. When the Great Sage entered the body of the Sunset Warrior, he thoroughly explained love and non-love, breaking the tangled fate. Then when the Great Sage leaves, the two bodies are doomed to disappear between heaven and earth. .
In case you ask, I'll tell you another one. Violet went back to make a wok, the supreme treasure was gone, the old cow died, Niu Xiangxiang became a dog, and the iron fan was later blind (third master, or the attendant of the top scholar of Bajie). The axe gang is gone, the third master is gone, and the gang is naturally gone.
