"Whoa......!"

When the ICBM disappeared from the screen, the entire classroom exploded.

"What's the situation? ICBMs disappeared? ”

"Spatial skills?"

"Who is that alien powerhouse, so powerful? At the very least, it has to be an epic powerhouse......"

In the classroom, Zheng Cheng's eyes were also a little surprised.

That's an intercontinental missile!

One shot is the ultimate weapon that can destroy a city and slaughter millions of lives.

Just disappeared so simply?

Bai Bin's voice continued: "Everyone sees, this is the real fear of professionals. ”

"In the video, the alien powerhouse who appeared in the early stage of the cataclysm is named Bai Ye, and he is an epic powerhouse of the spirit demon clan, Bai Ye!"

"White Nights?"

"Spirit Demon Clan?!"

Zheng Cheng's eyes flashed, and he remembered the content of the history class he saw on the day he woke up to his career.

"In 2357 AD, the first otherworldly fragment hit the Blue Star and merged with the Blue Star."

"The alien spirit demon clan in the otherworldly fragment rushed into the Blue Star, slaughtered the human race, and used the human flesh and blood to launch sacrifices, sent out the world coordinates for their people in the sea of stars, and guided their followers to step into the Blue Star!"

"In the same year, the Eagle Kingdom launched thirteen nuclear bombs in a row, destroying most of the spirit demon clan......"

Most of the world's current spirit demon clan has already merged with Blue Star, and the spirit demon clan is also the enemy of the human race today!

They occupy a portion of the Blue Star region, separated by a boundless sea, and wars are frequent.

Bai Bin continued: "The body of the White Night Demon King is a nine-star demon beast splitting wind fierce, and he is good at spatial ability. During the Cataclysm, it was already an epic powerhouse, and now its strength has stepped into the legendary level! ”

"According to our research and experiments, three-star professionals with a level of LV69 or higher are already not afraid of most thermal weapons."

"Bullets, artillery, bombs, etc., can't destroy their energy shield in a short period of time."

"Only by using a wide range of indiscriminate missiles to scrub the ground, or sneak attacks, can they be killed."

"So, this is also an important reason why our human race was completely defeated during the Cataclysm!"

"The heavens and all the races, especially the professionals, are a single life form that combines heaven and earth as a great force. They possess powerful spiritual powers, and can manipulate the elements and energies of heaven and earth, forming an energy attack that destroys the world in a short period of time. ”

"Others have powerful bodies that allow them to survive in any harsh environment without fear of artillery."

Bai Bin continued: "For example, the magma clan, they can swim and even survive in the magma with a temperature of up to thousands of degrees, can we Terrans do it?" ”

"There are also the deep-sea people, who are not afraid of the pressure of the deep sea and can dive thousands or even tens of thousands of meters to the bottom of the sea. As for us human beings, even the most advanced submarine probes can only dive to the bottom of the sea for about 10,000 meters, and they cannot last long. ”

"There are also the undead race, which is the natural enemy of our human race......"

Bai Bin's words aroused heated discussions among the students in the classroom.

"Energy Shield?"

"Teacher Bai means that the reason why our human race is defeated is actually because the alien race is too strong!"

"Yes, our thermal weapons are powerful, but our flesh is too fragile. One bullet can kill us! ”

"But we made it through! We humans also have professional ......"

"Not bad......"

Listening to the discussions of the surrounding classmates, Bai Bin nodded secretly.

Oh, yes.

Their human race has been able to survive under the attack of the heavens and all races for more than 300 years, and now they are confronting several races and occupying more than ten foreign race battlefields, which undoubtedly shows the strength and self-improvement of our human race.

And what they need is continuity, inheritance!

Bai Bin knocked on the table and continued: "Okay, be quiet, when you were watching the picture just now, did you find anything else?" ”

"The special race that Zheng Cheng just said, the nuclear bomb will make the space crack bigger and more numerous, and the teacher said that the alien professional is strong are just three superficial factors."

"Another important factor that has caused our human race to be completely defeated, and even almost wiped out the country. Or the main factor, in fact, is hidden in the picture just now! ”

"The fifth...... Cause! ”

"Has anyone found out?"

As soon as Bai Bin's words fell, the more than 20 students present looked at each other again.

"And a fifth reason?"

"Did you find out?"

"No! Isn't it the military who is using guns to stop the aliens in the video, what else is the reason? ”

"I don't know, think about it......"

On the seat, looking at Bai Bin's calm face and the discussions of the people around him, Zheng Cheng couldn't help but close his eyes and carefully recalled the picture he had just seen.

"An important factor that almost wiped out the human race...... Not the second video for sure! ”

"The second video just shows the power of the interracial powerhouse, and that's the first video."

"First Video ......"

In Zheng Cheng's mind, one picture after another appeared.

That's from the first video, with crumbling streets, panicked survivors, smoke and flames rising into the sky, and orcs slaughtering excitedly!

"Streets, survivors, orcs...... Well? ”

Zheng Cheng's heart suddenly moved, and a picture in the video suddenly froze.

It was a large group of fleeing survivors, covered in blood and carrying bags, running wildly in a panic.

And on their faces, they are wearing ...... Masks!

As if a lightning bolt pierced his heart, Zheng Cheng's eyes lit up suddenly.

"I see, it's ......"

"Virus!"

Zheng Cheng's words were interrupted by another voice.

All the students were silent, then turned back to look at the corner of the last row of the classroom.

There, a slender teenager was sitting.

His hair is thinning, he wears black-rimmed glasses, and his appearance is unremarkable.

Seeing that all the students looked at him, especially Bai Bin's encouraging eyes, he nodded again and said calmly: "Virus." ”

"These alien races that have descended to our Blue Star from other worlds, or other alien races, through spatial rifts, all carry viruses unique to their planets."

"Once on Earth, it spreads through air, blood, and contact, and there is no way to avoid it."

"Heh~"

He chuckled and said, "More than three hundred years ago, a kind of crossing was very popular in our Blue Star, especially in our Xia Kingdom. It is a story about modern human beings returning to the past for various reasons, relying on modern knowledge to chase the Central Plains and kill all directions. ”

"But I just want to say that they ignore the physical fitness of modern people and ancient people, especially the common virus attached to modern people, in ancient times, it was enough to cause a large plague that spread all over the country, even the whole world!"

"With the fragile physical fitness of ancient people, it is impossible to stop the virus in modern people."

"We are all human beings, and this kind of horrific thing can happen to modern people back in time. Then it is conceivable that after the alien creatures descended on our Blue Star, the virus they carried on them would not only exterminate all mankind, but it would be normal to infect millions of people. ”

"Let's just say that the orcs on the video just now, their bodies are so strong, and the power of the virus attached to their bodies, I don't think it's weaker than the Black Death, smallpox, cholera, etc."

"If you think about it, a world of aliens can infect millions of people. At that time, there were hundreds of alien races that entered our Blue Star......"

Although the boy did not finish speaking, the faces of all the students present changed.

Bai Bin lowered his head and checked the roster, nodded to the desktop and said, "Your name is ...... Chu He, right, a freshman majoring in military strategy at the Auxiliary Academy? ”

Chu He stood up and said, "Yes, teacher." ”

Bai Bin nodded and said, "You are very good, what you just said is exactly what I want to say." ”

Immediately, he stretched out his hand again and motioned for Chu He to sit down, and continued: "As Chu He said, the virus that befell our Blue Star alien race during the Cataclysm period is also the culprit that almost wiped out our human race. ”

"The maniacal blood virus, beast poison, and poisonous hair carried by the orcs are transmitted through the air and blood, and the infected people die of mental madness, nervous disorders, and cannibalism."

"The necromancy and poison carried by the undead clan are also transmitted through the air, and the body of the practitioner is stiff, the flesh and blood are defeated, and the respiratory system collapses, ......"

"There are also the dazzling and poisonous and spiritual poison of the spirit demon clan, the radiation and poison of the inferior clan, the fish scales and poison of the deep sea clan, the impurity and poison of the giant clan, etc., all of which caused the death of hundreds of millions of people at that time!"

"Under the erosion of countless poisons, our human race was completely defeated and almost wiped out!"

"Correspondingly, the poison in our human body also works on some alien races. But because their constitution is stronger than ours, they quickly overcome. ”

"Fortunately, this kind of thing was not curbed until the awakening of the first professional Ten Thousand Beast Spirit Master."

"Human scientists have also worked day and night to develop most of the vaccines to resist these combinations from foreign races, and they have successfully persevered."

"For more than 300 years, we modern humans have already developed hundreds of resistances to different poisons."

Suddenly, he said in a joking tone: "If any of you here can go back to the time of the Cataclysm and do nothing, go around a crowded place, maybe you can also cause a great plague all over the world!" ”

Teacher Bai Bin's words caused a lot of laughter in the classroom.

"Alright, that's a big deal."

Bai Bin clapped his hands, attracting everyone's attention.

"The topic of our lesson today is 'the practice and application of modern thermal weapons on the alien battlefield', because in the alien battlefield, because the rules of the world are different, the effectiveness of thermal weapons is greatly reduced."

"However, we humans have relied on alchemy, formations, and the special profession 'gunsmith' to re-improve the thermal weapon, so that it has also changed and can be effective for different alien races."

"For example, Lord Tang City, who is now outside the territory of the alien battlefield, is the strongest gunsmith!"

"And most of the nuclear bombs on our Blue Star have also been deployed in more than a dozen alien battlefields to resist alien ......"
