Alice's parents, who were pointed at guns by Wang Xiaotian, walked around the room with a sad face.

After the two walked to the kitchen, Alice's parents, after pressing the faucet and adjusting it a few times, came out under the sink and a small door leading downstairs.

"The laboratory is on the ground floor of this building, and this building is our home from the first floor to the fifth floor!" Alice's mother said.

Wang Xiaotian followed Alice's parents, began to walk down the small door, and entered another room.

Alice's father, this time came to the bedroom, pressed a few buttons under a small coffee table, and opened a small door.

The three of them walked down again.

In this way, when Wang Xiaotian followed Alice's parents to the negative third floor of this building, the room that appeared was no longer the room of the residence, but a metal door.

Alice's mother and father each raised a hand and pressed it on the metal door to scan their fingerprints, and their eyes were also on the electronic scanning port of the metal door to detect their pupils.

"Permission compliant, entry allowed." An electronic sound sounded on the metal door, which opened.

Wang Xiaotian followed Alice's parents into the metal door.

Wang Xiaotian looked around and found that inside this metal door, there was a huge underground research room, which was very wide, with five or six test benches and instruments.

There are also more than a dozen tempered glass covers in the room, and inside each cover, there is a humanoid monster, soaked in liquid.

Wang Xiaotian looked at these monsters in the tempered glass cover, which made him think of the humans who mutated into monsters in the monster space.

"How did you get these monsters? Didn't you say that Alice couldn't bring out the creatures in the monster space? Wang Xiaotian asked.

Alice's parents looked at each other and did not speak.

Wang Xiaotian raised his gun and pointed it at Alice's father's head.

"Give you a minute to get this straight, or I'll kill you all." You also know that I am not from your world, and I don't care about the laws of your world. Wang Xiaotian said threateningly to the two.

"Okay, I said.

That's right, Alice was a creature who couldn't bring out the monster world before.

But some of the cells and viruses that exist in her body can be transported to another time and space. Alice's mother said.

"Can Alice bring some cells to that world with viruses? So, the people in that monster world have become monsters, and it has something to do with you?

Did you make Alice carry the virus that made human monsters talk and bring it to that world? Wang Xiaotian asked in surprise.

Alice's father, after hearing this, nodded proudly.

"At the beginning, we didn't make any progress in researching human evolutionary drugs, but in another world, we have developed gene drugs that can improve people's lives, and the description and manufacturing methods of gene drugs, as well as the formula for drug composition, can be seen everywhere in radio commercials, and they have become open-ended drugs.

We used the formula of that gene medicine to optimize our evolutionary medicine.

We soon made a success in our research, and an unexpected trial allowed us to discover that our evolutionary drugs and the world's life-enhancing gene drugs could be fused and mutated.

The mutated potion is more powerful and can turn people into powerful monster warriors.

In order to determine the strength and evolution ability of various demon beast warriors, the ability to be controlled, and other data, a lot of live experiments are needed, and the number of live experiments has exceeded what we can control.

It just so happened that the world where Alice went was a good large-scale living experiment site for us. With a large population base, and very similar to our world in every way, a few years ago we let the drug virus we developed in Alice's body enter that world.

At first, the results were not ideal, but by chance, the drug virus successfully infected the world's first human, and produced a lot of latent and contagious.

It's amazing that people in that world are constantly turning into monsters, and humans are starting to evolve! Alice's father, the more he talked, the more excited he became, and his emotions were a little uncontrollable.

"You have caused the beasthood of humans in another world, and it is the two of you who have developed a virus to destroy that world!" Wang Xiaotian said with some surprise.

"We will not destroy that world, we will give that world a new life, the evolution speed of human beings has slowed down in the last few hundred years, we want to increase the evolution speed of human beings, but evolution will have some costs, survival of the fittest, that world will eventually evolve the ultimate monster, according to the data of the ultimate monster, we can optimize our potions, to optimize the human evolution channels and models of our original world." Alice's mother said feverishly.

"Excellent! Now that you have developed this virus, you should still have a hand in it, and I order you to hand it over, and I order you to hand it over! Wang Xiaotian asked Alice's parents.

Wang Xiaotian thought that the way he left this world could make most of the humans die, or the demon beasts would die and many other methods, which could not be done by him alone, but if there was the original code and inducing potion of the human demon beast virus, this seemingly impossible task would become much simpler.

"No, in the beginning we had a way to kill the virus, but as the virus evolved, it was out of our control. It's not just that we don't, even that world, which has gathered all their scientific researchers to experiment day and night, has not developed an effective way to fight against this virus that has evolved into a monster. Alice's mother said.

"You are so capable, you have developed a virus that can destroy all mankind!" Wang Xiaotian said in a mocking tone.

"This is to make people evolve, not to mention that the world, and it is not our world." Alice's mother argued.

"Then let the people of this world also be infected with this virus! In this way, scientists from two worlds will work together, and progress may be faster. Wang Xiaotian said and walked to the front of the experimental table.

Wang Xiaotian quickly operated on the controller of the test bench with both hands.

Alice's parents were surprised to find that Wang Xiaotian, an outsider, also knew some advanced medical terms.

Wang Xiaotian quickly found the source code of the virus and stored it in the liquid virus.

Wang Xiaotian called up the liquid test tube of the virus, set the vent flow direction of the laboratory, and spread the virus to the outside world.

"Don't, you're going to ruin the world, there's no antidote to this virus! You lunatic! The virus in this lab is released in our world, and the people in our world are different from that world.

The human beings there have been injected with special genetic drugs, and their physical functions are good before they can become monsters, and in this world, most people will be infected with this virus, and the nerves in their heads will be damaged, and only zombies with the ability to move and forage for food. Alice's father screamed and wanted to stop it, but Wang Xiaotian was too fast to stop it.
