When Lu Jiu came over, he saw an old man and a young boy sitting on a bench, smoking in the cold wind, neither of them wearing a coat.

Lu Jiu didn't expect Si Shen to smoke, "Why are you sitting outside? Isn't it cold?"

Si Xu saw Lu Jiu and put out the cigarette in his hand, "Come in after you have a cigarette."

Grandpa suddenly stood up from the bench and looked at Lu Jiu with hope, "Young boss, your ingredients are very good for Ah Xu's body. Do you have any ingredients that can help Ah Xu's condition? He has brain cancer..."

Grandpa's voice choked, he looked at Lu Jiu, his lips trembling, tears in his eyes, "Is there..."

Si Xu held Grandpa's trembling hand, "Grandpa, please don't be like this."

Grandpa was still staring at Lu Jiu stubbornly, "Are there any ingredients that can help this disease? If so, I will buy them no matter how expensive they are. Money is not a problem..."

Lu Jiu was confused by Grandpa's sudden action. After a while, he said, "All the ingredients in the store are helpful to his body. You don't have to worry too much. He will be fine."

Si Xu looked at Lu Jiu. He was sure that Lu Jiu didn't know about his illness, but Lu Jiu's reaction didn't seem like he didn't know.

Grandpa shook his head, "Don't comfort me. I know his situation very well."

Lu Jiu was helpless, "I really didn't lie to you. I have been conditioning his body. He will get better and he will be fine."

Grandpa was stunned for a few seconds, then looked at Si Xu.

Si Xu nodded, "It's true, he has been taking care of my body."

"Then...is there any improvement? What did the follow-up check say?" Grandpa was afraid to hear that there was no improvement. Lu Jiu was his last hope.

Si Xu's throat moved, wanting to say something, but he couldn't.

Lu Jiu knew that if the root problem was not solved, the symptoms would not disappear. No matter how many times he checked or how many medicines he took, his condition would not improve.

The tears in the old man's eyes touched Lu Jiu, and he comforted him, "There will be improvement. If you don't believe me, go for a follow-up check in a few days. You should be able to see the effect."

"Really?" Grandpa couldn't believe it.

"Really, you can go with you. It's too cold outside. Go in first." Lu Jiu urged them to go in.

Grandpa said yes repeatedly and decided to take his grandson for a follow-up check-up in a few days.

Grandpa went back to the private room first, but Si Xu didn't leave. He kept looking at Lu Jiu with an unclear expression.

Lu Jiu felt a little uncomfortable when he looked at her, "I just... couldn't bear to see him like this, he is so old... Sorry, I said too much."

"It's okay." Si Xu paused before saying, "Do you know about my illness?"

"I... know." Lu Jiu admitted it with a stiff upper lip, for fear that Si Xu would ask again, "How did you know?" This was really hard to explain, but fortunately Si Xu didn't ask any further questions.

Si Xu was silent for a moment, then he sighed, "I'm afraid that after the reexamination, he will be even more desperate."

"No, there will definitely be improvement..." Lu Jiu looked around, then glanced into the store, and took Si Xu's wrist and walked into the store, "Let's go to the second floor, I have prepared a gift for you."

Lu Jiu's hand was very cold, Si Xu let him hold him and walked all the way to the second floor.

"I have a medicine that will help your condition..."

After a pause, Lu Jiu told the truth, "It's a three-no product, do you dare to use it?"

Lu Jiu had to ask clearly, if he dared to give it, Si Xu had to dare to use it.

[It's not a three-no product! This is the product of the largest pharmaceutical company in the Demon Sea Plane Civilization! 】

Lu Jiu immediately said: Then can I tell him that this is the product of the largest pharmaceutical company in the Demon Sea Plane Civilization?

【No! 】

Lu Jiu: Then what should I say? Isn't it still a three-no product?

【……】

【Humph! 】

Lu Jiu thought for a moment: Then can I tell him about the existence of the Demon Hunting System? This way many things can be explained.

【You can try to see if you can say it. The system has a self-protection mechanism. You are the carrier of the system. If you violate the taboo, see what the consequences will be. 】

Lu Jiu was silent for a moment: Will the system drag me to the end?

【Who knows. 】

The tone of the system is very annoying.

"Dare to use it."

Si Xu's voice brought Lu Jiu back to his senses.

Si Xu smiled bitterly, "It has come to this, what else am I afraid to use?"

He believed in Lu Jiu.

Lu Jiu turned and went to the bar, squatting down and pretending to look for something, but in fact he opened the inventory and took out the primary gene enhancer.

He didn't dare to take it out in advance, fearing that the medicine would deteriorate or other situations would occur due to improper storage, so he kept it in the inventory without moving.

Lu Jiu walked back to Si Xu and opened his hand. In his palm was the light blue injection. The color of the medicine was very beautiful, and the shape of the syringe was also very unique. It was a small syringe with "high-tech" written all over it.

Si Xu took it and studied it in his hand. Lu Jiu had already prepared disinfected cotton balls in advance. Except for the food that was eaten, everything brought over from the Demon Sea Plane must be recycled and cannot be circulated, and the same goes for the syringe.

"I'm not very good at giving injections. You have to do it yourself." Lu Jiu handed the sterilized cotton ball to Si Xu.

Si Xu didn't ask or say anything. He rolled up his sleeves, exposing his upper arms, and used tweezers to pick up a ball of cotton and wiped the injection site. Si

Xu was methodical, but Lu Jiu was panicked, "But, it might hurt..."

Before Lu Jiu finished speaking, Si Xu had already injected the needle. There was no need for manual speed control. The medicine was automatically pushed in. Si Xu pulled out the needle, and Lu Jiu hurriedly pressed the needle hole with a cotton ball.

"What, what?" Lu Jiu was very nervous.

Si Xu smiled, "Why are you more nervous than me?"

"I, of course I'm nervous." This is something that is used directly on people. If there is any problem, he will be a murderer.

Si Xu returned the syringe to Lu Jiu, "This thing is very useful..."

Before he finished speaking, the color on his face instantly faded, and he could no longer stand. Lu Jiu dropped the things in his hand and caught him. Si Xu almost pressed on Lu Jiu, and Lu Jiu helped him find a chair.

"I... sit for a while..."

After finally helping Si Xu to the double chair beside the dining table, Si Xu fell into the chair and sat in with Lu Jiu.

Lu Jiu didn't know what kind of pain this was. He only knew that Si Xu must be in a lot of pain. Cold sweat kept dripping down. He grabbed Lu Jiu's arm and almost broke Lu Jiu's shoulder. Lu Jiu didn't know how long this pain would last. He didn't dare to move. He let Si Xu hold him and gently stroke his back, hoping to reduce the pain.

Lu Jiu frantically called the system in his mind: How long will the pain last?

[Ask others for information, 1 magic point for each question, do you want to continue?]

In the past few days, Lu Jiu has gained another 5 magic points from the scraps of food ingredients, and now has 11 magic points.

Lu Jiu almost roared: Do it yourself!

[The recessive gene will stop automatically when it is activated to 10%, and it will take about... 10 minutes.]

Ten minutes...

Lu Jiu has never felt that time is so difficult to endure, ten minutes almost felt like ten years.

There was blood on Si Xu's pale lips, and he didn't know whether his mouth or lips were bitten. Lu Jiu was stunned when he saw the color of the blood. It was not pure red, but with a faint silver color...

Lu Jiu blinked and looked again, it was really not pure red...

His eyes moved up and met Si Xu's eyes, and he was even more surprised. Si Xu's eyes were no longer black, but... silver!

Lu Jiu: "..."

Lu Jiu's numb head hadn't turned around yet, and he heard the system screaming excitedly in his head.

[Ahhh!!! Dad! Male god !!! Ahh

... ​ ​ ​ ​Ahhhhhh!!!!!!!!! Give me an autograph! Quick!!! No wait, it’s my idol’s birthday today, I want to give him a gift! The Demon Spirit Tribe is best at using the Demon Spirit Knife, Demon Spirit Sword and Demon Spirit Bow. I don’t have enough magic points to buy a set, so I can only barely buy a Demon Spirit Knife… Never mind, then I’ll use the Demon Spirit Knife. When Demon Spirit dad uses the Demon Spirit Knife, he’s so damn handsome! ! ! ! ! 】 藺九: … 藺九: … 藺九: Wait a minute, you want to use the magic points that you stole from me to buy a gift for your dad? 【These are not your magic points, these are the magic points I saved, they are my private property! 】 藺九: Where did you get your private property? 【I can get kickbacks for completing tasks, purchasing things, and recycling scraps.】 �九: ... �九: Do you want to give me a gift, or I will feel very ashamed. 【Don't dream, if you had worked harder, my magic points wouldn't be so low, how dare you ask for a gift?】 �九: I am your biological father! 【Even a biological father can't prevent a child from chasing his male god! Idols are the most important!】 �九: ... 【Quick, quick, quick, I've already bought it, please tell my male god that I like him very much and will always pay attention to him, come on! Love you, ( ` ) heart!】 Damn... This system is really good at adapting to local customs, why does it have to learn to chase idols! The inventory was hanging in front of Lu Jiu, waiting for him to take out the gift. It was said to be the Magic Spirit Sword, but in the inventory it looked like a wristband, with no trace of a sword at all. Lu Jiu: Are you sure you bought the right one? [What do you think the Magic Spirit Sword is?] Lu Jiu: I thought the Magic Spirit Sword was a sword. [This is a sword! Without the magic energy to activate it, it is just a wristband. After activation, it will immediately turn into a sword! Send it to him quickly!] Lu Jiu: Of course, I think instead of giving him this thing, you might as well give him an intermediate gene enhancer. What do you think? The system was silent for a few seconds before speaking listlessly. [I can’t send it away…] [Dear father, my idol is now in your hands. Please redouble your efforts and heal my idol. This may be the only remaining demon spirit in the world.] Lu Jiu: Just like the only remaining sea monster in the world? Master, shouldn’t you explain why the descendants of the Demon Sea plane appear in the Earth plane? It’s like this for me and your idol too. Don’t you think it’s strange? [Strictly speaking, it’s not strange. When the Demon Sea plane was destroyed and the space was raging, it’s not ruled out that the surviving descendants were swept to the Earth plane.] Lu Jiu: Even so, how did they survive without the magic element? [It’s not impossible to survive. As long as there are magic element crystals, it is entirely possible to support for a period of time.] Lu Jiu: How long is this period of time? [It is difficult to determine. The speed of time flow in the Earth plane and the Demon Sea plane is different. It is impossible to calculate how much time difference the surviving descendants will be caught in the space-time rift. The Demon Sea plane you see now is the new appearance after the destruction. How much time this process takes is impossible to calculate. ] Lu Jiu: I remember you said that I am the only existing bloodline of the Sirens. According to your current inference, I am not the only bloodline, right? [No, you are the only bloodline. ] Lu Jiu: But this does not make sense. Since I exist, there must be other Sirens on the Earth plane. For example, my biological parents. [If you have not awakened as a Sirens, just having Sirens genes does not count as Sirens. ] Lu Jiu: What do you mean? [I loaded the Earth civilization and searched for some cases from ancient times to the present. The situation like Idol is not a special case. It occasionally occurs in other countries. Humans call this disease a "genetic disease" and there is no cure. ]

[It is true that there is no cure, but the disease is false. This may be a way for the descendants of the Demon Sea plane to preserve their bloodline - intermarry with humans, give birth to offspring, and preserve their bloodline. When the genetic genes become dilute to a certain extent, they will be suppressed by human genes. Human genes will prevail, and what is manifested is a human being who can survive without magic energy. Only when the genetic genes are too strong and manifest without magic energy, will a situation like idols occur.]

Lu Jiu: Are there other descendants on Earth?

[Unless they begin to awaken, all I have detected are humans.]

There must be other descendants. Lu Jiu is very sure of this. He and Si Xu are examples.

[The time has come, send the gifts quickly! 】

Lu Jiu came back to his senses and hurried to see Si Xu. The color of his eyes returned to black.

"Are you okay?" Si Xu's condition was recovering, and his heavy breathing gradually calmed down.

Si Xu let go of his hand, "Are you hurt?"

Lu Jiu moved his shoulder, which was sore and painful. He knew without looking that Qing Zi would definitely not be able to escape.

"Fortunately, it should be fine." "Sorry." Hugging Lu Jiu was just a subconscious reaction

. Only in this way could he draw enough strength to resist the pain.

"It's okay, how do you feel now?" Seeing that the system was so excited, this demon clan must be very powerful.

[Gift, gift, gift! ... Si Xu smiled, "Very good, very magical kind of good." [Gift aaaaaa——!!! !!! !!! 】 Lu Jiu: ... Lu Jiu took a deep breath, stood up, and like a magic trick, stretched out his hand in the air and grabbed a black thing in his hand. "There is another gift..." [The tone is wrong! The attitude is wrong! I have to express my feelings at this moment seriously and carefully! ! ! ! ! ! ! ] Damn it... [Ahhhhhhh——!!! ! ! ! ! ! ! ! ] The crazy system launched a sound attack on Lu Jiu. Lu Jiu: ... Lu Jiu's head is going to explode! He took two deep breaths and solemnly handed over the gift with both hands. Si Xu raised his eyebrows. Lu Jiu seriously relayed the original words of the fan Tong, "There is a Tong who likes you very much. It asked me to pass on this birthday gift. It will always pay attention to you. Please do your best in the future." Lu Jiu thought about it and suddenly made a pen refill gesture, "I love you~~~( ` ) Heart!" " Pu cough cough cough..." The sudden killing power of pretending to be cute was too strong. Si Xu was caught off guard and coughed. Lu Jiu's face darkened. "Sorry..." Si Xu was having a hard time holding back his smile. Lu Jiu had a look of despair on his face, "Laugh if you want to, I can handle it." Si Xu hurriedly pulled him over, trying hard not to laugh, "Since my debut, I have only received a gift from one fan, I won't accept this one, give it back and thank him for his support." Lu Jiu: "..." The system didn't scream this time, it just swiped Lu Jiu's head with qaq. Lu Jiu resisted the urge to throw the system away, and tried his best to persuade him, "Just accept it, this gift is a little special." Si Xu looked at him, and Lu Jiu looked at him. After a while, he belatedly remembered that the only gift that Si Shen had ever received from a fan was not the black star bead that he had given, right? He knew that Si Xu never accepted gifts from fans, so he thought of asking the courier to run to the same city and deliberately not write the return address so that the gift could not be returned, so that Si Shen would have no choice but to accept it. "The Black Star Bead is very useful, thank you." Si Xu kept looking at him, not missing any of his reactions. Lu Jiu: "..." Lu Jiu's ears instantly turned red. Lu Jiu: "No, you're welcome..." Ah ah ah ah ah ah!!! Isn't it better to live in peace? Isn't it better to pretend not to know? Why do you suddenly make it clear? It's very embarrassing, okay? ! Lu Jiu screamed in his heart, and the system screamed in Lu Jiu's head. Lu Jiu felt that he was only one gift away from going crazy. Lu Jiu made up his mind, "This gift and the potion come from the same place. It is a weapon tailor-made for you. You must accept it." Otherwise, he was worried that the heartbroken system would turn his brain into an ocean. The system took out all the magic points that it had saved for so long just to buy this gift. If it is rejected again, it would be too pitiful. Lu Jiu couldn't bear to see the system cry like a dog. Si Xu stared at the black wristband-like thing and pondered for a moment, "Is it really not from you?" He had a history of giving gifts and not acknowledging them. Lu Jiu: "..." Lu Jiu asked the system's opinion in his mind, and the system gave him some reputation with grievance and reluctance. Lu Jiu: "It bought it, and I'm delivering it for it. It's a gift from both of us." Si Xu paused, "You guys?" Lu Jiu: "Yeah." Si Xu leaned back in his chair, "Thank you for your kindness, I won't accept it." The system burst into tears, and cried very loudly. Lu Jiu: ... Lu Jiu's head felt hot, and he rushed over to grab Si Xu's right arm. Si Xu wanted to hide, but Lu Jiu pressed him into the seat, holding Si Xu's right arm tightly, and the magic sword that looked like a wrist guard was pressed on Si Xu's right wrist, and it was entangled tightly in an instant, and he couldn't take it off. Lu Jiu soothed the crying system: Okay, it’s sent out, don’t cry… He raised his eyes and met Si Xu’s eyes as deep as a pool. The two were very close to each other. Lu Jiu was kneeling on Si Xu’s legs at this moment, and his whole body was lying in Si Xu’s arms. Si Xu’s right arm was held by Lu Jiu, so he could only use his left arm to circle him, fearing that he would fall. Lu Jiu: “…” Lu Jiu became frightened in a second, “I’m sorry…” Just as he was about to climb down, the arm on his waist suddenly tightened, Lu Jiu instantly moved forward, and someone grabbed his neck, and warm lips were already covering him.

Lu Jiu suddenly opened his eyes wide, his mind was empty, and only the systematic scream of "Ahhhhh let go of my male god and let me come" remained.

Lu Jiu's lips and teeth were pushed apart, and his mind exploded. He nervously wanted to push him away, but his hands subconsciously grasped Si Xu's clothes. He didn't know whether he wanted to push him away or get too close... After

the kiss, both of them had a little unstable breathing. Lu Jiu was still in a daze when he heard the male god's low and hoarse voice echoing in his ears.

"I like you for a long time."
