Returning to the modern world again, Wang Xu didn't have time to use the technology against the world to build his own super pharmaceutical company, and a bad news came out.

The bad news came not from people, but from the old yellow dog who had been with him in the zombie plane.

The old yellow dog is really too old, Wang Xu asked a veterinarian to estimate that this is an old dog at least thirteen or fourteen years old, which is equivalent to a ninety-year-old human old man.

When Wang Xu arrived, the maid who usually took care of the old yellow dog told him that the dog had not eaten much since two days ago, just like an old man who knew his destiny, always lying at the door waiting for something.

"Are you waiting for me?" Hearing the servant's words, Wang Xu squatted on the ground and stroked the old yellow dog's head.

The old yellow dog's eyes were blank, and after smelling his breath, he licked his hand with great effort, and shook his tail weakly twice.

Wang Xu can feel its happiness and its weakness.

If nothing else, the old yellow dog's life is these two days, and it has reached the point of running out of oil and lamps.

"Go make a steak." Wang Xu sat next to the old yellow dog and waved his hand at the maid.

The maid, a black woman in her forties, hurried to the kitchen when she heard the noise.

A few minutes later, the steak was served, and Wang Xu tore the steak open with his hands and fed it to the old yellow dog little by little.

I don't know if it's a return to the light, or seeing the owner come back, the old yellow dog has a yearning for life, and it actually staggered to its feet.

It's a pity that the old yellow dog is really not good, and it can't eat it after two bites, so he just rubs his face against Wang Xu's pants, and his mouth makes a whining scream.

Seeing this scene, the maid took out a handkerchief to wipe her tears, and choked up: "Sir, I have seen it with a veterinarian, and the veterinarian said that it was organ failure, and it is too old." ”

"Organ failure!" Wang Xu's eyes suddenly lit up, nodded thoughtfully, and said, "Today is a holiday for you, you go home and rest." ”

After the maid left, Wang Xu picked up the old yellow dog and put it in the kennel in the living room.

After doing all this, Wang Xu quickly ran up to the second floor, opened the safe hidden behind the bookcase, and took out a syringe from inside.

"The reason why people die is because of the aging of cells and internal organs, if we can rejuvenate the cells and internal organs, will we not have to die?" Wang Xu pierced the syringe into the medicine bottle containing the evolution solution, and inhaled all the evolution liquid in one dose into the syringe.

With this in mind, he took the syringe and went downstairs to the old yellow dog's kennel.

In the kennel, the old yellow dog ate something, and saw Wang Xu, the owner, who was resting with his eyes squinting at the moment.

Wang Xu squatted on the ground, stroked its head with his hand, and pricked the needle under the skin of the old yellow dog's neck.

The old yellow dog felt the pain, opened his eyes with great difficulty, and looked at him in a daze.

Wang Xu patted its head, signaled the old yellow dog not to move, and said softly: "You're going to die, after this injection, maybe you won't die." ”

The old yellow dog wanted to lick Wang Xu, with a whining wail in his mouth.

After a while, half of the evolution liquid in the needle tube was injected, and Wang Xu suddenly thought that the old yellow dog was so weak, and a dose of evolution liquid could not resist.

Thinking of this, Wang Xu pulled out the needle, intending to take a look at the situation first.

In the eyes, the old yellow dog, who had been injected with half an injection, stuck out his tongue as if he had a heat stroke, and was covered in sweat.

Before Wang Xu could say anything, the old yellow dog whined, rushed out of the kennel, and ran away like a joy.

"Does it work?" Wang Xu looked at the appearance of the old yellow dog, and a slight smile appeared on his face.

People die because cells age.

After the age of 25, the cells begin to age, and with time, they gradually decrease, and the immunity also decreases.

From a medical point of view, if the aging of cells can be curbed, the failure of organs can be curbed, and the life expectancy of people can be increased.

The evolution liquid in Wang Xu's hand can strengthen physical fitness in all aspects, including the strengthening of cells.

Maybe it's not a panacea, but for people with organ failure, it's no less than a panacea.

"Lao Huang, come back!" Wang Xu shouted and called the old yellow dog back.

He pinched the muscles of the old yellow dog with his hands, observed the hair on its body, and checked the physical condition of the old yellow dog.

"The evolution liquid can strengthen the physical fitness, but the physical fitness of the old yellow dog has not been strengthened, but it is not in a dying state. In this way, the evolutionary fluid should have played a role, but the role is not to strengthen, but to make up for the aging organs and cells. Judging from his appearance, Wang Xu can only draw such a conclusion, and no more will work.

However, he did not give up, but took the old yellow dog to the pet hospital, intending to give it a full body examination.

Three hours later, Wang Xu came out of the hospital with an extra report in his hand.

The report shows that the pet hospital's estimate of the age of the old yellow dog is about 10-12 years old, instead of 13-14 years old, and it is 1-3 years younger.

"Here, I'll give you another shot and see if you can get younger." After Wang Xu came back with the old yellow dog, he picked up the syringe and gave him half an injection.

After this half a stitch, the old yellow dog did not become younger, but became stronger.

It was originally a native dog, but after half a needle was injected, it actually had the meaning of a bulldog, and the muscles of the whole body bulged.

At a glance, it seems that I have seen Schwarzenegger in the earth dog world, and his appearance is indescribably weird.

"With the second injection, the old yellow dog's age has not changed, but has become stronger. In other words, the increase in lifespan of the evolution liquid is a one-time thing, and its main function is to increase physical fitness, maybe long-term injections can make people live to be two or three hundred years old, but it still can't make people immortal. After two experiments, Wang Xu has a deeper understanding of the role of evolutionary liquid.

It seems that the wasteland plane is a bit interesting, and according to the ability of the evolutionary liquid, the wasteland plane is likely to evolve into a high-martial plane in the late stage of evolution.

Of course, this evolution will depend on years, or even decades, and cannot be overnight.

"The water in the wasteland plane may be deeper than I thought!" Looking at the evolution liquid in his hand, Wang Xu's eyes flashed with a solemn color, wondering if it was a robot factory against the world, after growing enough combat robots, it would take the lead in tidying up the wasteland world.

Judging from the efficiency of the anti-world robot factory, after increasing production, thousands of combat robots can be produced in half a year.

The combat robots here are definitely weapons born for war, and they are even more powerful than the T800 robots in the Terminator.

Once equipped with electromagnetic guns, electromagnetic shields, and electromagnetic high-explosive shells, a combat robot is comparable to a regimental combat unit.

The wasteland plane is only the beginning of the apocalypse, the evolution of zombies has not yet begun, and thousands of tireless, insensitive robots are enough to push several provinces.

Seeing Wang Xu pondering, the old yellow dog jumped excitedly.

Wang Xu was not annoyed when his train of thought was interrupted, he looked at the old yellow dog that had changed greatly, rubbed its head vigorously, and said with a smile: "I can't call you Lao Huang in the future, you are now muscle yellow." ”

"Wow!" The old yellow dog circled around him, full of energy, as if Wang Xu had seen it for the first time.

Wang Xu played with him for a while, and when the sun was about to set, he thought of another pet and said, "Let's go, let's go underground and see how the zombie baby is doing." ”
