In the Age of Lords, I became the Lord of the Undead

After waking up, Ye Yang found himself back to five years ago, traveling to "King's Journey", and became a low-level undead in the dark camp of the game.
Fortunately, he awakened the SSS god-level talent: Undead Extraction!
SSS talent Undead Extraction: can extract any unexpected items from the dead soul.
"Ding! Congratulations to the host for successfully extracting the soul of the Skeleton Tyrant, and get an additional SSS-level skill card: Summon billions of skeletons!"
"Ding! Congratulations to the host for successfully extracting the soul of the Undead Overlord, and get an additional SSS evolution card: Undead Overlord Evolution Card:"
From then on, Ye Yang led his undead army to easily destroy any boss! Destroy any bright camp!
In the previous life, he joined the holy light camp of justice, but it was full of intrigues and was calculated everywhere. Countless efforts were all in vain and became the wedding dress of others.
Since I am reborn this time, I will throw myself into the darkness! !
Since I come with resentment, I will be the enemy of the world!
When the two worlds were completely connected, Ye Yang found that he was invincible!
