The counterattack system is only available in the Mahayana period

"What a natural killer." Jiang Li sighed.

Luo Ying has been around in the apocalypse for ten years, and now he is naturally not afraid at all when facing zombies.

But Luo Zhu was different. She had grown up in a peaceful world. Luo Ying just gave her some tips on how to defeat zombies as quickly as possible. He trained her with two on the way, and she learned how to cut off heads easily.

Moreover, her expression remained unchanged. It seemed that seeing corpses or blood had no effect on her.

That's why Jiang Li felt this way.

The physical education teacher who turned into a corpse was a first-order zombie, and Luo Zhu took out the first-order brain core from its head.

"There was too much movement just now, which attracted a lot of zombies." Jiang Li appeared behind Luo Ying like a ghost, shocking Teacher Huang and others.

The movement just now was naturally not the movement of killing zombies, but the sound of students screaming.

Luo Ying and Luo Zhu separated and went to kill the two exits of the corridor. The King Ming's method could not be used, and the sword fell with his hand, and the zombies' heads fell like rain.

All the zombies in the entire teaching building were killed by the brother and sister.

They have not yet become strengtheners, and they have reached this point with only the power of one layer of Qi training period.

After the zombies were cleared away, the brother and sister returned to the classroom.

"Thank you." Teacher Huang said. She did not expect that this humble student would change so much, as if he had become a different person.

Luo Ying took the brain core handed over by her sister.

"This kind of thing is called a brain core. There is an energy in the brain core, called aura, which can make people stronger." Luo Ying put the brain core against his forehead, intending to teach the students how to become strengtheners. After all, Luo Ying could not Always protect them.

"Imagine invisible hands growing out of your body, pulling out the spiritual energy from your brain core and stuffing it into your body."

Teacher Huang and his classmates saw several wisps of blue gas actually coming out of the brain core and entering Luo Ying's body.

There was a slight crackling sound in Luo Ying's body, which was building muscles and bones and cleaning the bruises in the body.

"A long-lost feeling." He gently clenched his fists, feeling the power and becoming the first strengthener in this life.

By the way, the first Qi training period was Luo Zhu.

"Mr. Jiang, please help me see how many first-order zombies there are in the school."

"Four, each in..."

To go from an ordinary zombie to a first-level zombie, you need to eat a lot of people, and the school naturally lacks most people, so it is easy to evolve a first-level zombie.

"I'll be right back." Luo Ying got up and left after hearing the location reported by Jiang Li.

Not long after, Luo Ying came back with four brain cores and handed one to Luo Zhu.

Luo Ying had repeatedly told her sister what needed to be paid attention to, and Luo Zhu easily became the second enhancer.

Luo Ying distributed the three brain cores to Teacher Huang and two classmates with better conduct, and taught them step by step how to become enhancers. There were survivors from several classes in this building, but Luo Ying was not familiar with them. You can't just randomly pick someone to become a strengthener. If the other person is timid or selfish, then a brain core will be wasted.

Luo Ying explained a few words, such as tying books to the body and wrapping tape to prevent zombies from scratching. For example, these three enhancers have a certain resistance to zombie viruses. Ordinary zombies cannot infect them. They can infect the zombies in the school. Clear the area, establish a stronghold around the school, and collect supplies nearby.

This is the safest way. They don't have to worry about the first-order zombies coming, because the brother and sister will kill all the first-order zombies in the city.

Seeing that the Luo Ying brothers and sisters were about to leave, some classmates felt that the brothers and sisters would be safe around them, so they shouted: "Aren't you going to stay and protect us?"

Luo Ying did not answer the question and left directly.

"Tch, why are you pretending?" The end of the world is approaching in a hurry, and some people have not changed their thinking. They think that everyone is just a classmate, so there is no difference.

Teacher Huang said coldly: "Does Luo Ying owe you anything and he still stays to protect you?"

"But, but aren't we all classmates, shouldn't we help each other?"

"He didn't help you just now?"

"Of course I have to help people to the end. If I had his strength, I would definitely stay and protect everyone." The man said brazenly. Anyway, he was not really as strong as Luo Ying.

Teacher Huang ruthlessly exposed his lies: "I thought you would save your relatives."

The man was speechless, because if he became an Enhancer, he would really choose to leave everyone behind and save his parents.

If it was a peaceful environment, Teacher Huang would not be so mean, but after she witnessed the defeat of the army and the birth of the Enhancer, she realized that the environment had changed and the previous peaceful era was gone forever. She must It is necessary to change some of the students' wrong ideas. If anyone continues to have the ideas of the classmate just now, it will definitely cause disaster in the future.

Teacher Huang turned his head and warned the students seriously: "Students, times have changed. Don't have naive ideas and expect others to risk their lives to save us. Only by being self-reliant can we be self-reliant and survive."

"Now we three enhancers are leading the team to search and rescue the survivors in the building, clear out the zombies, and establish the teaching building as a safe zone."

…

There are very few first-order zombies now. They only appear in densely populated places, such as supermarkets, hospitals, schools, etc. The brother and sister followed Jiang Li's instructions and took the shortest route to deal with the first-order zombies.

However, at this stage, the brothers and sisters could not absorb so many brain cores, so they found some temporary self-rescue organizations formed by the private sector, and gave brain cores to the organizers of the organizations to help them become enhancers, and combined brain cores, enhancers and zombies. Teach them the knowledge.

…

Three months later, zombie whales returned to the sea, and a large number of cities were reduced to ruins. The existence of enhancers began to become known to everyone. Countries and chaebols used a large amount of manpower and material resources to expel zombies from less affected cities, establish safe zones, and continuously strengthen , thicken the fence.

People endure the pain of losing loved ones and rebuild their homes.

Each safe zone has formed its own rescue team, which is responsible for cleaning up zombies around the safe zone and conducting rescue operations in nearby areas.

In the past, countries complained about population expansion, which led to resource shortages. But now, population is the most important resource.

Population means strength, which means that more zombies can be cleared, the construction system of the safe zone can be improved, and the safe zone can be strengthened.

At the same time, people also recognize strengtheners and recognize the power of individuals.

Enhancers are talents that all safe zones desire. Safe zones will promise all kinds of benefits, including women, food, and power, just to recruit enhancers.

When it comes to the strengtheners that all safe zones are eager to recruit, they are the Luo Ying brothers and sisters who always have the ghost of Tota floating around them.
