Opening the door, the white-haired Grandpa Liu was waiting for Lin Lin outside.

"Grandpa Liu, why don't you dye your hair?"

Lin Lin said with a smile: "If you dye your hair black, maybe how many old ladies will take a fancy to you." ”

"Haha, old."

Grandpa Liu raised his hand and touched his white hair: "People are old, what are you doing with those, you see how comfortable I am now enjoying flowers and walking birds every day." ”

After joking, Grandpa Liu turned around and walked towards his house, and said, "Lin Lin, come, come with grandpa, I have something for you." ”

Lin Lin followed Grandpa Liu all the way to the basement of Grandpa Liu's house.

The basement is very empty, but there is nothing else except a painting on the wall, and that painting looks very precious, Grandpa Liu should not give himself such a valuable thing, but it is not that painting, and there is nothing for himself here.

"Grandpa Liu, what you're going to give me won't be this painting, right? It looks so expensive, I can't afford it. Lin Lin said half-jokingly.

Grandpa Liu turned around and scolded with a smile: "Who do you think of your Grandpa Liu?" Would I give this thing away? ”

As he spoke, Grandpa Liu walked to the painting, and a pupil recognition device popped up in the painting, and after scanning Grandpa Liu's eyes, a secret door slowly opened, and an elevator car appeared in front of the two.

Seeing the wall splitting, Lin Lin was a little shocked: "Grandpa Liu, this? ”

"Hehe, boy, I said I wouldn't give you junk, come in with me." Grandpa Liu looked at Lin Lin with a smile, and motioned for Lin Lin to follow him into the elevator.

After entering the elevator, I saw Grandpa Liu take out a magnetic card without any markings from his body, and after swiping it on the panel, the elevator began to descend.

When the elevator just started, Grandpa Liu closed his eyes, obviously not wanting to answer Lin Lin's question in the process, and Lin Lin didn't open his mouth in the same way.

After about five minutes, the elevator finally stopped, and when he stepped out of the elevator, Lin Lin felt like he was in the laboratory of a technology company, where dozens of robots were working.

"You may wonder why I have all this stuff in my basement, and what I'm here to do."

Grandpa Liu said to Lin Lin on the side: "The place where we are now is six hundred meters away from the surface, and this is the laboratory I asked my son to build in order to copy a thing. ”

Turning back and glancing at Lin Lin deeply, Grandpa Liu continued: "Gene enhancement liquid, which is known as a top secret thing in the alliance, users can get a five-fold increase in ability, and it is an all-round enhancement, and there will not even be sequelae. ”

"This is exactly what I want to give you, I successfully copied the alliance's genetic enhancement liquid, and modified it on the basis of it, the enhancement liquid I made here is three times more effective than the alliance's enhancement liquid."

With a wave of his hand, the mechanical arm next to him took out a tube of red and blackened genetic enhancement liquid from the box and handed it to Grandpa Liu.

"I've observed a lot of people, and you're the best of these people, so I finally decided to give you this tube of booster solution." While speaking, Grandpa Liu handed the enhancement liquid in his hand to Lin Lin, and waited quietly for Lin Lin to take it.

"Grandpa Liu, it should have taken you a long time to copy and improve this enhancement liquid, right?" Lin Lin did not choose to take the strengthening solution, but asked his own question.

"yes, it took me about thirty years, and that time was really ......"

Casually put the enhancement solution on the table next to him, Grandpa Liu sighed: "During that time, I didn't even accompany my family, and I was so dedicated to tinkering with this enhancement solution, I didn't even know about the death of my wife." ”

Speaking of this, Grandpa Liu's tone began to become sad: "It's also ironic, the day of my wife's funeral actually happened to be the day when I succeeded in improving the enhancement solution, and at the last moment of her life, she didn't complain about me, but thought that I could fulfill my dream." ”

"Perhaps...... Maybe I can succeed with her help. ”

took out a handkerchief and wiped the tears from the corners of his eyes, Grandpa Liu smiled and said, "Let your little guy see a joke, how about it?" Have you thought about it, should you drink this tube of fortifying liquid? ”

Lin Lin was silent, although he usually chatted with Grandpa Liu, but this enhancement liquid is a life-related thing, although he is the only one in the family now, but what if his parents don't have that much? If something happens, you can't become a white-haired person to send a black-haired person, this matter really has to be considered carefully.

"Are you afraid that something will go wrong?"

As if seeing that Lin Lin was worried, Grandpa Liu said: "Don't worry, I have the top medical robot team here, as long as you don't explode in an instant, no matter how seriously injured, they can save you." ”

"If you're still not sure, you can make a memory backup here."

Grandpa Liu pointed to a machine on the other side: "In this way, even if something happens, I can clone a body for you, and I can also adjust you to the best body." ”

"Besides, I've experimented with the guinea pig over there, and it's going to be fine."

Following Grandpa Liu's gaze, I saw a half-meter-long white mouse curled up inside a glass box.

"You mean guinea pigs?"

Lin Lin said with an ugly face: "But I see that this 'little' mouse is not very small, it is almost the size of a dog." ”

"It's just a minor side effect, but don't worry, I've re-debugged it and it won't happen." Grandpa Liu reassured.

Looking at the enhancement liquid on the table, Lin Lin swallowed his saliva, if it really has three times the effect of the alliance enhancement liquid, it can bring a full fifteen times increase to himself, if it is successful, he can completely compare to the geniuses of other races advertised in the news.

Lin Lin slowly reached out and picked up the tube of strengthening liquid, and asked again, "Grandpa Liu, are you sure there won't be any problems?" ”

"Don't worry, there's no problem."

Without waiting for Grandpa Liu to finish speaking, Lin Lin raised his head and drank all the enhancement liquid, and after drinking it, he smashed it and smashed his mouth, feeling a little sweet.

"This booster doesn't seem to be as unpleasant as I thought, and it has a bit of a sweet taste." Lin Lin muttered to himself.

Then he stood in front of the mirror in the laboratory and observed himself, and found that there seemed to be no change, nothing he felt, just like taking a sip of a drink, and turned his head to look at Grandpa Liu: "Grandpa Liu, why don't I feel it at all, it can't be a failure, right?" ”

As he spoke, he saw Grandpa Liu looking at him with a smile on the corner of his mouth, and Lin Lin wanted to say something, but he felt that a warm current began to spread from his abdomen to his internal organs and limbs, and there were also bursts of headaches.

"Oh, I forgot to tell you, my head will hurt very much after drinking, but don't worry, I'll faint soon." Grandpa Liu said at this time that he would have a reaction after drinking the enhancement solution.

"Why didn't you say it sooner?" Lin Lin gritted his teeth and said the last words when he was awake word by word, and then he lost consciousness, and the whole person lay on the floor of the laboratory.

"Haha, are you little guy still afraid of disfigurement?" Looking at the funny Lin Lin, Grandpa Liu couldn't help but laugh.

It wasn't until it was determined that Lin Lin was completely unconscious, Grandpa Liu came to the control panel, operating on the keyboard with both hands, as if he remembered something, and turned his head to look at Lin Lin on the ground.

"Well, what's your name? Wisdom Eye, right? Grandpa Liu said to the wisdom eye on Lin Lin's wrist.

"I'll open the lab to you, this little guy might sleep for a few days, there's a nutrient tank over there, and after you move into the lab's system, throw the little guy in, and I'll leave it to you to take care of him for a few days. By the way, I have some things in this computer that can help you grow a little more, and you can also use the equipment in the lab to upgrade your watch. As Grandpa Liu's hands kept tapping on the keyboard, the control authority of the laboratory slowly opened up to Zhiyan.

After doing all this, Grandpa Liu turned around and walked onto the elevator and left the laboratory.

After Grandpa Liu left, Zhiyan controlled the mechanical arm, threw Lin Lin into the nutrition tank, turned around and began to upgrade the watch.

At the same time that Lin Lin entered the nutrient tank, Lin Lin's body began to absorb the nutrient solution frantically, and in less than three minutes, the nutrient solution in the tank was reduced by a small half, fortunately, there was enough nutrient solution reserves in the laboratory, so as not to be unable to keep up with the devouring of Lin Lin's body.

Inside Lin Lin's body, the strengthening liquid began to clean up those abnormal cells inside the body, and all of them were discharged through the pores, eliminating impurities, while the strengthening liquid also entered the interior of other cells, starting from the molecular structure to transform Lin Lin's body, in this process, Lin Lin's body was slowly covered by impurities and became a black man.

As for Lin Lin, he felt extremely comfortable in a coma.

……

In the elevator, Grandpa Liu was talking to someone on the phone.

"You gave that thing away?" The person on the other side asked cautiously.

"yes, I sent it out, what are you going to do? Catch me? Then come on. Grandpa Liu said loudly.

"No, no, no, you misunderstood, I just asked, asked, how dare I arrest you."

The person over there seemed to be frightened, and quickly explained: "I just want to know, is the person you gave is reliable?" ”

"Huh."

Grandpa Liu snorted twice and said, "The people selected by Lao Tzu are not more reliable than those second-class goods you selected?" What, are you doubting my vision? ”

"Ouch, my dad."

It was his son Liu Mo who was on the phone with Grandpa Liu, and Liu Mo said: "I just want to know who the person you have chosen is, don't doubt me like that." ”

"Doubtful?"

Grandpa Liu suddenly said in an excited tone: "Lao Tzu hasn't doubted you yet, but you have guessed my thoughts?" Then I'll be honest, the people I choose are thousands of times better than those crooked melons and cracked dates you chose. You don't look at who your Lao Tzu is, can your vision be bad? ”

"As for who it is, Lao Tzu won't tell you, let you find out by yourself, but I can warn you, competition is competition, if you dare to use the next means, Lao Tzu will immediately fly over and kill you, Lao Tzu will come over now, it won't take long."

After listening to what Grandpa Liu said, Liu Mo said excitedly: "Dad, have you broken through again?" ”

"What, do I have to report anything to you? You remember, you are my son, I am your son, you can't control me. After finishing speaking, Grandpa Liu hung up the phone and added this number to the blacklist.

On the other side, Liu Mo called again, and when he heard a string of busy sounds, he could only smile awkwardly.
