Chapter 639 Chapter 639 “This is… your gallbladder?!” Even Emmanuel was taken aback. As a doctor, he thought his medical knowledge was extensive enough, but what he was witnessing still surpassed his understanding. It seemed that there were genuinely many ambitious individuals who were constantly researching projects against humanity, and they had made significant progress. What was terrifying was that the world was oblivious to them. “That’s right,” answered the Snake Master, his face ashen and veins bulging, appearing in great pain. “The most powerful thing about snakes is their venom, and the gallbladder is the organ that stores the venom. It’s also a vital part of a snake’s body. Today, I will exchange it for my sister’s life.” “What need do I have for it?” Emmanuel asked with amusement. “Good question.” The Snake Master pulled out a strange needle and forcefully inserted it into his gallbladder. With that, his already grimacing face became even more ferocious, and his eyes turned bloodshot. It was evident he was in immense suffering. Mackenzie watched from the side and felt a chill run down her spine as her hands and feet grew cold. “This is a mini bomb. Now I’m giving you the remote. Once you prèss the Sᴇaʀ*ᴄh the ƒind ηøᴠel.nᴇt website on Gøøglᴇ to access chapters of novels early and in the highest quality. button, my gallbladder will explode,” said the Snake Master as he tossed a black object to Emmanuel, who caught it through his clothes. After confirming it was harmless, he held it in his hand. “Now, my life is in your hands. With my blood as the oath, I pledge to be your Snake Slave. Henceforth, I will comply with your every command,” the Snake Master swore bitterly. Emmanuel stared into his blood–red snake eyes, unable to detect any deception. However, with his wise goddess of a wife by his side, he turned back and asked, “What do you think, Mackenzie?” “Maybe… we should give that thing a try?” She considered, pointing to the detonator in Emmanuel’s hand. The Snake Master turned awfully grim in response. “Good idea.” Emmanuel was also considering pressing it. He knew Mackenzie wanted to test the Snake Slave’s reaction and determine if this thing was genuine or fake. “Wait!” the Snake Slave quickly raised his hand and shouted, blood dripping from his mouth, his face enveloped in menace. “Since I’ve entrusted you with my gallbladder, I will take it even if you still want to kill me. But you must sparè my sister, or I swear in the name of the King of Snakes, I will come at you even as a ghost!” “My, so ruthless. I’m scared.” Despite what Emmanuel said, he showed not a sliver of fear on his face. That said, he still let go of the assassin in red ultimately. The female assassin was shocked, never imagining that Emmanuel would spare her for the third time. She was a professional assassin, for heaven’s sake. She never expected to live after missing once. Yet, she continued to live even after failing to kill the man before her three times. “Let’s go, Mackenzie,” said Emmanuel as he walked toward Mackenzie. “Alright.” Mackenzie nodded, understanding and supporting Emmanuel’s décision. She could tell that the Snake Master hadn’t lied, and this pair of siblings were actually quite pitiful. If he could deceive her with his storytelling skills, then he had some talent worth keeping alive. “How are you doing, senior? Are you okay?” The assassin in red quickly helped the Snake Master up, still calling him her senior. Many members of the organization were still unaware of their kinship. If their lives weren’t at stake, the Snake Master would never have revealed to Emmanuel that she was his sister. “I’m afraid my days are numbered…” said the Snake Master with despair. With the failure of this mission, his reputation within the organization would plummet.
