I Traveled Through Time and Joined the 749 Bureau

Wu Jun, who had just lost his job, traveled to the ancestral planet and returned to Earth with three major guesses and a trouble. He immediately handed over all the secrets to the country and then joined Bureau 749 and embarked on the path of truth-seeking and mystery exploration. Bureau 749: We are hidden in the crowd, we are willing to give, we bear the darkness, and we firmly believe that the interests of the country are above all else. Zuxing's three major guesses about the earth: First, the mysterious side is protecting you. Second, current humans possess genes from the previous four eras. Third, the universe is dangerous, be careful about the moon, develop Mars, and don't break the wall. As for the trouble, I never admitted it. Wu Jun said with a cigarette in his mouth. But sure enough, our world is really not simple! ! !
