At the Beginning of the Spiritual Realm, I Summon the Invincible Sword.

When the spiritual realm appears, the world enters a new era. You can become a spiritual person by transplanting your spiritual core and awakening your spiritual martial arts. Lu Yi came through time travel, but he didn't expect that he was only a D-level talent. Can you only become the lowest level spiritual person and then go to the spiritual realm to do civil engineering? He feels that his future is not so bright... Many years later, when Lu Yi became the strongest spirit person, he finally realized: "It turns out that I have an emperor-level talent!"
