The heavy wooden door was pushed open with a creaking sound, and everything in the wooden house came into view. An old man in shabby clothes, about eighty or ninety years old, was sitting on a recliner in the house. He raised his eyelids when he heard the sound, and his cloudy old eyes saw Du Ershi lit up.

The voice was hoarse: "Second brother! Second child, you are back!"

"It's me! Grandpa, I'm back to see you!" Du Er squeezed out a smile and walked to the old man on the wooden recliner.

The old man raised his chicken-claw-like hand to grab Du Er's hand, but Du Er shrank back subconsciously, not wanting the old man to touch it.

Eleven could see clearly from the side, Du Er was very afraid of the old man touching him, there must be a reason for this.

Sure enough, the old man sighed after being rejected when he grabbed Du Er's hand, "You haven't come back once in more than ten years, so why did you suddenly come back to find me?"

"Yes, Grandpa, I want the medicine you gave my friend last time, do you still have it?"

"No more!" The old man shook his head, "Those are the last few pills, I gave them all."

"Can you match?" Du Er asked again.

"No! I can't find some things now." The old man shook his head, "Second brother, that medicine is not a good thing, what do you want it for?"

"It's not me, but my friend. Grandpa, can you help me?" Du Er begged.

"It's not that I won't help you, it's that some of the ingredients in the formula are gone. Second child, that medicine is harmful. Has your friend harmed someone by using it?"

"Yes! Grandpa, are you still worthy?"

"It's a crime!" The old man shook his head. "Such vicious things shouldn't exist, and I was the one who... hey..."

"Grandpa, can you give me the recipe? I'll make it myself." Du Er asked for the recipe.

The old man shook his head, "The formula has been burned by me, so I can't give it to you."

"How could this be?" Du Er glanced at Eleven, who was so cold that his heart trembled.

He fell to his knees with a plop, "Grandpa, please help me! The lives of my wife, children, and parents are in the hands of others. If you don't give me the medicine, they will die!"

"You killed someone?"

"It's not me! It was the person who came to look for you that time who used this medicine to harm someone. They found me! Grandpa, it doesn't matter if I die, but my parents, my wife and children are innocent, please!"

The old man shook his head, "I told you before that this medicine is not a good thing. If you harm others, they will not let you go. Do you know now?"

"Grandpa, I understand, but I can't do anything now, please help me!" Du Er begged bitterly.

The old man looked at Eleven who was standing there, "Is this the creditor?"

"Old man, I'm not a creditor, I'm here to seek an antidote for our young master." Eleven replied.

"Master? Are you a servant?"

"I'm a bodyguard!"

"A person who can have a bodyguard with your skills must have a prominent status!" The old man looked at Eleven for a while with his cloudy old eyes, and sighed: "Sooner or later, you will have to pay back if you come out to mess around! What a crime!"

Eleven didn't speak, just looked at him quietly, the old man stood up from his chair and motioned for Eleven and Du Er, "Come with me!"

Seeing the room his grandfather entered, Du Er didn't move, "I'll just wait outside."

Seeing his fearful eyes, a trace of contempt flashed in Eleven's eyes and strode into the room.

The room was very dark and exuded an unpleasant smell. Second Grandpa Du closed the door in disappointment when he saw that only Eleven followed in.

He walked to the closet in the room and opened the door, a giant python poked its head out from inside, and Eleven stood on the ground looking expressionlessly at the python spitting out the letter.

"Aren't you afraid?" Du Er's grandfather looked at Eleven in surprise.

"Afraid?" Eleven sneered, "It's just a long worm, what's so scary? To tell you the truth, I can turn it into a puddle of meat in a few seconds."

Second Grandpa Du looked at Eleven complicatedly with old eyes, sighed, reached out and pushed the python's head away, rummaged in the cabinet, and talked while searching.

"I have lived ninety-three years, and I can be regarded as a person who has experienced wind and rain. When I was young, I did not do bad things. I played tricks on people, which hurt people a lot. Now the retribution in my old age has come. When I am old, no one cares. One day I will see King Hades with my legs crossed, maybe I have done too much evil, and God will not let me die, so I just let me suffer alone."

"They also earned a lot of money outside, why don't you follow them to enjoy happiness?" Eleven asked.

"I think so too, but I'm a Gu player. My son and daughter-in-law are afraid of me. Didn't you see that my grandson didn't let me touch his hands just now? He was afraid that I would harm him. Be a man like me, even close relatives." It's pathetic that people are on guard!" Second Grandpa Du laughed at himself.

Eleven didn't know what to say, Du Er's grandfather must have done bad things and harmed people while playing Gu, the karmic cycle of retribution was not good, he harmed people in the past, and now all the retributions have come to him, there is nothing to be pitied.

Second Grandpa Du rummaged through the cupboard for a while, then took out a wooden box and handed it to Eleven, "This is what you want."

Eleven reached out to take it, he was a little surprised, "Aren't you afraid that I will harm you? I am a Gu player, and I can harm people anytime, anywhere."

"I'm not afraid!" Eleven said lightly, "I'm not afraid to tell you that before I became a bodyguard, I was a professional killer. Many people died in my hands. If people like me are afraid, it's a joke."

"So that's it! So that's it!" the old man murmured, "That Gu is made by crushing blood-cursed worms into powder, and the box I gave you is the antidote, only one pill."

"Aren't there two pills? Why did you only make one antidote?" Eleven asked back.

"The medicine is not just one pill. I spent a lot of money to make several pills, but they were all bought at a high price. The antidote was not easy to make, so I only made one pill. I thought I would never need it in my life. "

"What about the recipe?" Eleven asked.

"The formula is also in the box, you can take the antidote with you." The old man replied, "But let me remind you, the antidote is not easy to mix."

"Okay, thank you!" Eleven put the box away, "If you want to leave here, you can follow us."

"No need, I have done a lot of evil things in my life, and being lonely is the inevitable end. I only hope that after I give you the antidote and formula, you can convince your young master to let my grandson's family go."

"As long as the antidote works, we won't hurt Du Er, but if the antidote doesn't work, it won't be the same result. Without our young master's help, I will also strip Du Er's family alive."

Eleven's words were too threatening, Second Grandpa Du smiled bitterly, "Are you worried that I will deceive you with an antidote? Don't worry, I have fully realized it now, and I will not gamble with the lives of my children and grandchildren. "
