Li Yi was overwhelmed by the favor. He did not expect that the Underworld King would help to upgrade the demonic sword.
Li Yi was just thankful that the Underworld King did not kill him.
He would never expect such benefits.
"You should go back. When you are strong, I will use your power to open a passage and lead the demons to kill the gods together with you."
Li Yi was overjoyed when he heard the Underworld King's words. This was a good thing.
At that time, if he could get the support of the demon army, he would have more confidence in dealing with the gods.
"Thank you, Underworld King."
The Underworld King waved his hand and a dark portal appeared behind Li Yi.
Li Yi bowed to the Underworld King and walked into the dark portal.
When Li Yi woke up again, he found himself lying in the secret room with the demonic sword in his hand.
Li Yi immediately checked the information of Deaths Descent.
