After Bai Bin asked, the entire playground was silent, and no one answered.

"Hehehe......" Bai Bin smiled lightly: "It seems that you classmates are still a little shy, then I will order someone." ”

Zheng Cheng secretly said in his heart that something was wrong, this old man actually looked at himself.

Among the more than 20 people in the entire classroom, it seems that he is the only one who has met Bai Bin and is an acquaintance.

Sure enough, Bai Bin pointed at Zheng Cheng: "Zheng Cheng, please answer this question." ”

As soon as the words ended, more than 20 students in the classroom began to whisper.

"He is Zheng Cheng!"

"I'm so handsome, I have a comparison with me!"

"I heard that Zheng Cheng has slept with more than a dozen girls in our auxiliary college!"

"? It's so awesome, it's really envious......! ”

After all, there are about more than 1,000 freshmen in the entire auxiliary college, but there are only two who can be treated as S-level freshmen.

A nine-star professional tree shepherd, Cui Xiabing.

The other is Zheng Cheng, who is a three-star priest!

Listening to the discussion of the students around him, Zheng Cheng's forehead twitched.

Slept with a dozen girls?

Damn, I want to too!

He got up helplessly and said, "Professor Bai, I think there are three main reasons why our Blue Star Humans were defeated during the Cataclysm more than three hundred years ago. ”

"First, as you said, thermal weapons are the most lethal to carbon-based organisms."

"As long as he is a carbon-based creature and a flesh and blood body, even a giant, he can't stop the cannon fire that covers the sky and the sun."

"As far as I know, there were hundreds of alien races that invaded our Blue Star at that time. For example, the Ice Giants, the Inferior Clans, the Orcs, etc., these creatures are also unable to block thermal weapons, and can be easily torn apart by our thermal weapons on the battlefield. ”

"But at that time, the enemies we faced were not only these carbon-based creatures, but also some special energy races, elemental races. They are not afraid of thermal weapons. ”

"For example, the ghosts, demons and other clans of the undead clan, the demon clan of the demon clan, and so on. Thermal weapons easily pierced their bodies, but they were unable to do even the slightest damage. ”

"In the face of these special aliens, of course, our human defense line is completely defeated."

Zheng Cheng continued: "The second reason is the idea put forward by scientists in the seventeenth year of the cataclysm. ”

"At that time, in order to stop the endless army of the undead, many countries chose to use the nuclear bomb as the ultimate weapon."

"It did take effect at that time, annihilating most of the undead creatures."

"But soon after, we found out that the spatial rifts that appeared on Earth were bigger and more numerous, and the alien creatures that entered the Blue Star from the alien battlefield were even stronger!"

"After continuous research, scientists believe that the explosion of a nuclear bomb on the Blue Star body will make the space barrier between the Blue Star and the alien battlefield, and even between the alien planet, thinner and more cracks."

"Some of the powerhouses of the alien race who were originally stopped by the space barrier will also step into the Blue Star for this reason."

"So during the cataclysm, the global provisional coalition government stipulated that high-power weapons such as nuclear bombs should not be used on the territory of Blue Star."

"It is precisely because of this that our Blue Star Terran was completely defeated in the early days of the Cataclysm, and we continued to lose territory and population."

"Only after the forerunners have grown up can they stabilize the front, and then counterattack the alien race and enter the alien battlefield!"

"Third, there is the difference in the rules of the world. The effect of thermal weapons is reduced under the influence of the rules of the world, and it is far less powerful than before the cataclysm, which is why the alien leader is driven straight in. ”

Zheng Cheng's words caused the surrounding classmates to nod their heads.

They learned all of this in high school.

"Bang Bang Bang ......"

Bai Bin applauded: "Zheng Cheng, it seems that you learned fairly well in the culture class in high school, and you have not forgotten these important contents. ”

"You may be seated."

Zheng Cheng nodded, and then sat down.

Bai Bin continued: "The answer that Zheng Cheng just said is the correct answer recorded in the book. ”

"And now that you're in college, you're among the elite of all the Blue Star humans. In the future, I will also set foot on the battlefield of the alien race and fight for the survival of my Blue Star Terran......"

Listening to Bai Bin's narration, Zheng Cheng's eyes moved.

The correct answer in the book?

What do you mean?

Could it be that there are other so-called 'answers'?

"Of course, there are several other reasons besides these three reasons."

Bai Bin was on the computer, and the entire classroom became dim, and a light curtain appeared in front of everyone.

It was a battle.

The picture is blurry and the sound is noisy, but there is no doubt that it is a battle taking place in the city!

On the screen, the entire city is in flames, full of panicked crowds and angry aliens.

These alien races are the most famous 'orc clans' in the alien battlefield.

They are tall, thick-skinned, and take pleasure in eating people.

Countless orcs rushed to kill people in the city, they killed people when they saw them, and they continued to devour humans in large gulps.

The whole city was full of blood and corpses.

There were occasional gunshots in the city, but they didn't do much damage to the rough-skinned orcs.

At the same time, Bai Bin's voice rang out from the darkness.

"This is a precious video of a spatial crack appearing in a city in my Xia Kingdom in the year 2034 AD, and humans resisting the orcs."

With Bai Bin's explanation, the picture changed again.

Military vehicles and tanks received orders, and they drove into the city, formed positions in a corner of the city, and gathered the survivors.

Finally, the orc army made contact with the human military position.

"Fire!"

"Fire!"

"Fire!"

With one command after another, countless fiery snakes shot out from the Terran front.

Bullets and artillery shells formed a steel front within more than 300 meters of each other.

Any orcs who approached this front were easily torn apart!

No matter how big they are, no matter how rough their skin is, no matter how thick their flesh and blood, they can't stop the dense bullets!

Cannonballs fell from the sky and fell into the crowd of orcs, instantly blowing up seven or eight orcs.

Stumps and severed bones continue to fall from the sky, staining the entire street blood-red!

Bai Bin's voice continued to sound: "At the beginning of the cataclysm, our army was equipped with all kinds of firearms that were the most advanced in the world at that time. ”

"Not to mention ordinary guns, there are hundreds of heavy weapons such as Type 81 wheeled self-propelled rocket launchers, Hongqi 9 missile air defense system, ZTZ88 main battle tank, Red Arrow 10 tracked anti-tank missile vehicle, PGZ04A integrated prevention and control system of missiles and artillery, PHL-191 480 km rocket launcher, and hundreds of other heavy weapons, Dongfeng Express ......"

"The Air Force also has J-30 heavy fighters, White Emperor-11 intelligent fighters, heavy bombers and so on."

"Just like the content on the video, these alien races have no power to resist in the face of our army's heavy thermal weapons, and they are easily torn apart!"

"Some spatial cracks have just appeared, and the alien race has just emerged, and they will be hit by missiles millions of miles away, and all of them will be annihilated!"

In the darkness, Bai Bin's voice was slightly excited, but then it became a little muffled.

"It's a pity...... Professionals! ”

"Pros?"

More than 20 people present were repeating this word.

"Among the aliens, there are also professionals!"

"They have an energy shield, also known as a talisman shield, and at that time there were also people who called it AT force field, energy magnetic field, hehe...... At that time, some people called them overlord color domineering, life energy, gene locks, etc., and they were all the same thing anyway. ”

Bai Bin laughed at himself: "These professionals, they are not afraid of artillery, they shuttle through the battlefield on their own, and they can easily break through our defense line!" ”

Accompanied by Bai Bin's voice, there was indeed an accident on the video.

I saw that in the dense artillery defense line, more than ten orcs with golden light suddenly rushed out from behind the orc formation!

The bullets hit them, and they could only splash a few sparks.

And they relied on their own energy shields to rush to the Terran military front with artillery fire.

Many Terran soldiers roared and rushed towards the group, but they were easily killed.

And with the addition of this group of orc professionals, the Terran military front collapsed in less than five minutes.

After the artillery fire stopped, the ordinary orcs rushed up again with a roar, killing all the survivors and soldiers hiding behind the military camp!

Bai Bin's voice continued to sound: "This situation was very common on the battlefield at that time. ”

"There are often high-level professionals of the alien race, who rush into the Terran positions with artillery on their shoulders and easily slaughter human beings."

"After all, we humans are just ordinary flesh and blood, but these alien races are powerful professionals."

"Powerful torrents of energy and treacherous rule skills are simply not something that flesh and blood and ordinary artillery fire can stop."

"Even ......"

With Bai Bin's voice, the picture turned again.

This time it was a piece of sky, and the picture was still shaking, obviously from an airplane or a fighter jet.

At the end of the sky, there was a deep purple light that stretched across the sky.

Underneath the spatial rift, there were countless strange-shaped alien races surging densely.

"This is located in the Atlantic region of the South American continent of Blue Star, numbered NM-134, which is the largest space rift discovered by humans at that time."

"At that time, the Eagle Country, the strongest country in Blue Star, dispatched more than 120 F-18 Eagle fighters, F-25 Raptor fighters and other fighter formations to prepare to blow up this space rift."

"It's a pity ......"

On the screen, hundreds of fighters and bombers fired hundreds of missiles in an instant.

They drew white lines in the air, accompanied by a sonic boom that shot towards the spatial rift.

And at this moment, hundreds of figures suddenly appeared in front of the spatial rift.

They float in the air, some with wings, some with a single horn on their heads, some with tails wagging behind their backs, and some like giants.

In the face of the incoming missiles, they struck one after another.

With the flickering of light, these hundreds of missiles were easily blocked by them.

And there are dozens of extremely fast figures shuttling through the fighter group, easily blowing up this fighter formation!

More than ten minutes later, there were only more than 20 fighters left in the fighter formation, and they withdrew from the battle sequence in embarrassment and fled into the distance.

In the distance, a white dot appeared.

ICBMs.

But with the advent of intercontinental missiles, hundreds of alien figures suddenly gave way to a road.

Another figure covered in white light appeared, and he just reached out and grabbed it in the direction where the ICBM was flying!

In the next second, a spatial fluctuation suddenly appeared around the ICBM, enveloping the ICBM and disappearing without a trace.

Yes.

The ICBM, which is enough to be called the strongest weapon of the Blue Star, is gone!

There is still a chapter at eight o'clock in the evening.
