After hearing this, Wang Mang was speechless.
But the blood coffin was right about one thing.
This fellow was indeed knowledgeable.
In fact, if Wang Mang had any problems with his cultivation, he wouldn't need to consult the system anymore.
Especially when he thought about how the black-hearted system charged for any questions, Wang Mang couldn't help but fly into a rage.
Thinking of this, Wang Mang nodded and said, "Alright! In the future, when I kill enemies, I can let you absorb and process their corpses."
Hearing this, the blood coffin immediately nodded in satisfaction. Then, it turned into a palm-sized blood coffin and flew into Wang Mang's palm.
"Let's go! Little guy! Get out of where you came in!"
"In addition, you and I should also swear a Great Dao oath!"
Hearing this, Wang Mang didn't hesitate to swear a Great Dao oath on the spot.
