Devil's Agent: Starting with Signing with Satan

Golden lawyer Wu Heng travels through the steam era where demons are everywhere. At the beginning, he was regarded as a devil and was surrounded by the Holy Knights! Good news: You can trade with the real devil to gain the ability to kill the Holy Knights. Bad news: The devil's bargain only charges flesh. Worse news: Even if you exchange all your flesh and blood, it won't be enough to kill the knight. You can only exchange it for fifty copper coins. You win the capital! At a critical moment, he relied on his previous experience, transformed into capital, bet his flesh and blood, and started an economic game with the devil, turning danger into safety. Not only that, he also discovered business opportunities, opened a law firm, and made the business with the devil bigger and stronger! Beelzebub, Lord of the Flies, you are gluttonous and devour everything, and you are given a pair of toenails; Siren Leviathan, your huge body is boundless, covering the sun and sky, taking away the sense of pain; Succubus Lilith, you confuse people's hearts and turn all living beings upside down. Keep your skin three feet away; Ouroboros Mammon, you are insatiable and extravagant, and your internal organs lead you; Lucifer, the First Fallen, it is most difficult for you to overstep the gods. I will give you my soul. ... As Wu Heng's business empire was established, deep-seated demons continued to emerge, and the secrets of the empire began to be revealed. Gradually, he also discovered the difference in his own flesh and blood.
