After dressing as a cannon fodder, I study hard

But the invasion of this parasite is faster than anyone imagined. On the street, in the city, or at an ordinary workplace, there are endless screams and explosions, and people are chained almost before they have time to react. The sound of the explosion made people scream in shock, and everyone fled in a hurry. The first thing they did was to escape home and seal themselves in the house to isolate them from the invasion of all monsters.

The dean looked at the shocking crowd in front of him, and immediately decided to open the previous isolation ward. Lin Xi proposed to give everyone a mark, and after taking the film, get an armband. The purple armband means safety, and the red armband means parasites. For some people who seem to be more serious, the hospital decided to cut off the largest part of the parasites first, as Grandpa Wang did, to delay the onset time.

Everyone's heart is full of fear and panic. Some people hide their faces and cry because of the hopelessness that may come, but doctors don't have such time to panic. In the hospital, they are the direction of people's hearts.

The dean divided several people who were still healthy into research groups, first experimented with what the monster was afraid of, and then studied the relevant components.

Children in hospitals are most likely to be parasitized, because some children have poor hygiene habits and like to eat their hands, which greatly increases the probability of ingesting mucus or parasites.

Among the children, the results of Wang Duo's physical examination surprised everyone. This child turned out to be the only one among the children who was not infected!

Lin Xi and Lu Hanshuang had known before that the key to resolving this ignorant battle was a child, but Lin Xi and Lu Hanshuang never thought that this child would be so close to them.

"Perhaps there is something special about this child." Lin Xi said, she squatted down and looked at Wang Duo at the same level. When everyone was panicked and didn't know what to do, she asked Wang Duo softly, "Wang Duo, next we may I want you to have a physical examination, take a blood test, and study the secret that you cannot allow monsters to parasitize your body, are you willing?"

"..." Wang Duo pursed his lips and pursed his mouth. He stared blankly at Grandma Wang who was at a loss. Grandma Wang was startled. She hurriedly led Wang Duo behind her. If it becomes a research tool in the laboratory, won't the child's life be ruined?but--

"Is it just a physical examination?"

"It's just a physical examination." Lin Xi said, "We may need enough samples for further research, but we will guarantee the safety of Wang Duo's life."

Grandma Wang looked at the people around her and wiped her face: "Duoduo, are you...going?"

Wang Duo looked a little confused, as if he didn't know how important he was at this moment.

The surrounding crowd was evacuating in an orderly manner under the guidance of the dean and the hospital leaders. Some people who showed signs of madness were injected with sedatives and put into separate wards. Those who were too late burst into the ward, which was horrible for a while.

The sound of cars on the road and screams of people running away kept appearing, no one knew who would be parasitized or exploded next, and no one was sure if that person would be themselves——

Chaos.

Total mess.

"I'll go." Wang Duo looked at Lin Xi and said, "I'm a man, and I want to protect my grandparents."

"Good boy." Grandma Wang sent Wang Duo to Lin Xi's side. Lin Xi and Lu Hanshuang rushed to the isolation ward of the hospital, put on the relevant equipment, took Wang Duo with them, and experimented with other colleagues.

Because of Lu Hanshuang's rudimentary carrying skills, he carried the equipment and walked like flying. Lin Xi and the researchers worked in the laboratory, and Lu Hanshuang helped everyone do some work within their capabilities.

Gradually, people who stayed at home and feared that they would be wiped out in the next second or that they would infect their family members gradually gathered in major hospitals. The major hospitals have been communicating with each other to test the blood of people who are not infected one by one to find out whether they are infected. There are special substances.

Parasitic explosions broke out in all places, and all places had to save themselves. Order was destroyed in the chaos, and people who smashed shops and robbed appeared on the roads and streets. No one knows when this doomsday will end, no one Do you know how long this situation will last——

Is it going to last until everyone is numb?

Under all the pressure, there is also some good news. Hospitals around the world have discovered that such parasites are transmitted through blood and contact. This parasite is not a high-level intelligent creature. Expand, expand, expand.

They use human beings as hosts to reproduce, and use human energy and flesh and blood as their own nourishment. When they are stimulated by the outside world or mature, they will release a very powerful gas to remove themselves from this discarded nourishment. Break free, and everything that reproduces can find the next host.

They are not afraid of fire, and even a temperature of several hundred degrees Celsius still cannot damage the mucus at all, but they are afraid of the saline-alkali environment, and are afraid of alcohol and other substances that can decompose their bodies. Once the structure of the mucus is broken, this parasite will become A puddle of muddy water. After experimental research by the Academy of Sciences, it was found that the liquid decomposed by parasitic organisms still contains a certain amount of cosmic matter, which cannot appear on the earth.

After a short period of social suspension, the country sent troops to help resist parasites everywhere. Everyone wore thick protective clothing when they went out on the street to ensure that their bare skin would not be parasitized by parasites. Order was re-established, and everyone remained the same. Carry forward.

In the same year, after comparing the elements and energies in uninfected blood samples from all over the country, it was discovered that Wang Duo's blood has special meaning for parasites.

Wang Duo's body contains a very small amount of cosmic element, which was later named Duo. As long as human blood contains a small amount of Duo element, parasites will hate such a growth environment and will not choose to parasitize.

Lin Xi, Lu Hanshuang, and Wang Duo were sent to the highest-level prevention and control command center, and together with experts from all over the country, they studied where the Duo element entered the child's body, and how other people adjusted their blood environment to contain the Duo element. environment--

Everyone placed the source of Wang Duo's Duo element on the child's favorite "beautiful stone".

This is an alien meteorite, with the residual mucus of parasitic organisms attached to it, but these parasitic organisms that should have reproduced in large numbers did not reproduce in large numbers on the meteorite, but there was no movement at all.

"There is a saying in ancient times, for example, there is a miasma in front of your eyes, and the mist in the miasma is poisonous. Many people will die in the miasma if they stray into the forest. , there must be a kind of herbal medicine that can get rid of this miasma."

Lin Xi analyzed: "It shows that this meteorite is the culprit for carrying parasitic organisms to the earth. More than one such meteorite is scattered all over the world, causing a species invasion on the largest scale."

"That's right." Other researchers also discovered this situation, but now meteorites are rare and precious. Facing such a huge population and epidemic groups, how to choose has become a problem.

Traces of meteorites have been found in the major centers where parasites broke out. Everyone used meteorites to conduct experiments again and again. Finally, one year and three months after the struggle between parasites and humans, a parasitic patient passed the adjustment. It destroys its own blood environment, making it impossible for parasites to obtain the energy they want from the blood, and finally turns into a liquid that is purified and discharged by the human body bit by bit.

Lin Xi constantly refreshed his technical level through experiments again and again. When the system reminded him that he had successfully recruited the world, Lin Xi and Lu Hanshuang had a deeper understanding of life.

While Duo Element became the hope of the new era, Lin Xi and Lu Hanshuang also completed their mission and returned to the original world. The familiar system prompt sounded, and Lin Xi subconsciously had a feeling of nostalgia.

"Crack, click, how about the first world, let's be simple." The system happily approached Lin Xi to claim credit, but when it saw Lu Hanshuang, the system was startled, "I said it's no wonder the space is automatically upgraded, so it's because she came Yes, the world feeds back a lot of energy, so it is automatically upgraded."

"Long time no see." Lin Xi greeted the system, and the system responded, "I wanted to come back earlier, but something got stuck on the way."

The system said, "You guys were too bold in the first world, you dared to do it before the story line started, but you also got a blessing in disguise, it was a recurring world, and while reducing casualties, you also accelerated the research process, so The rating of this world is very high, and the feedback points obtained are also very high, please check it."

Lin Xi and Lu Hanshuang had scored [-] points in this reduced-difficulty novice recruiting world, and Lu Hanshuang's abilities had been strengthened a bit.

There was an extra contract in Lin Xi's contract book, and the contract was actually a parasitic creature from the previous world. It had a new name, Duo Beast.

[Duo Beast: A soft and easy-to-breed parasite, but be careful of its explosion. 】Lin Xi had no intention of taking out the Duo Beast in real life, and he didn't even have a similar thought. The Duo Beast, as an alien invasive species in a situation similar to the background of the real world, caused great harm to that world. A devastating blow.

Although that world is a recurring world, the invasion of parasitic beasts will happen countless times, and it will be solved countless times by those who have been recruited, but the damage and pain caused during that period of time have really existed.

Lin Xi and Lu Hanshuang cherished each other even more because of what they had experienced. The two had no space for themselves for a long time, so after the system exited the space cursing, Lin Xi and Lu Hanshuang also retreated and returned to the place where they traveled. in a homestay.

Time seemed to pass only for a moment.

Lin Xi took the initiative to lie beside Lu Hanshuang, the two of them breathed quietly, feeling the peace and beauty of the original world, everything seemed so unreal.

Until Lin Xi climbed onto Lu Hanshuang's body and kissed her lips.

"Is this reality?" Lin Xi asked.

"Yes." Lu Hanshuang replied.

Slowly, a ray of breeze caressed the delicate flowers.

The flower branches tremble slightly, revealing infinite fragrance.

I never, never want to experience that kind of end times. Every painful moment is the deepest torment in my heart.

But, fortunately, Lin Xi and Lu Hanshuang have each other.

You have all the courage to heal and warm your blood.

"Have you heard the sea?" Lu Hanshuang asked.

The author has something to say: that is the sound of waves.
