Look at the invincible, huge, and unknown monsters on the screen.

Tang Ling's forehead was covered with cold sweat, but there were too many inexplicable thoughts in his mind.

"In this era... Even the oxygen content has changed. ”

If the oxygen content in the air was still the same as in pre-civilizations, such a huge organism would not have been possible, because the concentration of oxygen would not be enough to meet the needs of large organisms.

But if modern times are a nitroxic environment, how can humans adapt? Oxygen poisoning will occur, just because the lungs will not be able to withstand it in the first place!

And if it is a high-oxygen environment, human individuals will definitely undergo drastic changes to adapt to the times, how can it be no different from the previous civilization?

Or is it that the speed, strength, and even some inexplicable changes in human beings are already a kind of change? Do all of these require a nitrox environment?

What kind of inexplicable times are these?

Tang Ling's mind was a little confused, and he couldn't connect some of the knowledge he knew with the current era.

In fact, even if he has a super good memory, just a few days of reading will not allow him to understand that much.

In recent days, he has found himself in a strange state of 'memory', that is, as long as the theories he has read in the book, even if they are just glanced, and there is nothing he understands, he will understand it afterwards and come up with some knowledge in contrast.

For example, if he knows the Pythagorean theorem, he will know the mathematical derivation process of demonstrating the Pythagorean theorem.

Tang Ling didn't bother to think about this point, but at various moments, thinking in combination with knowledge seemed to have become a certain instinct of his mind.

But what does this instinct do...?

"Here, how did this happen? Is the situation getting worse and worse? In less than three seconds, Tang Ling had already thought a lot, but the whisper of talking to himself in the air interrupted Tang Ling's thinking.

Even the sky has become very concerned? Tang Ling raised his head and looked at the monster that was still eating frantically, and was shocked.

At this moment, the watchtower, a man who seemed to be the commander who had been sitting in the middle of the tower without saying a word, finally stood up.

His tone was slightly hurried.

"Emergency, emergency, battlefield area No. 6, coordinates 33.76 appear suspected of being a third-level fierce beast. Preliminary observations have high-end capabilities. ”

"Damn, I hope it's not space!" The commander couldn't help but burst into a foul language at this time.

When the word space fell, the brows in the sky suddenly furrowed.

"It is recommended that the Purple Moon Warriors immediately form a five-person squad and go to eliminate the target. Or, sortie..."

"Warriors of the third order and above." The commander paused and uttered the last words.

At this moment, Yangkong suddenly turned his head to the stunned Tang Ling and the others and said quickly, "Suspend the lecture." I don't know if you're lucky, but you can see a big show on the first day here. ”

After saying this, he walked to the command platform in front of the big screen and directly grabbed the command of the commander.

"Area 7, Area 5, Area 4, all retreat immediately."

"Combatants in the coordinate range 33-43.65-89 are also immediately evacuated."

"The patrol garrison is fully on first level security and is ready to activate the M777 howitzer. Grant Level 2 access to the 'Sky Eye' to connect to the city protector in order to carry out precise strikes on targets. ”

Speaking of this, Yang Kong hesitated a little, and then said again: "In addition, two GM-45 155 mm towed howitzers have also entered a state of readiness. ”

"Report to the command center, the right to use the shells...", the console of the command center immediately heard the voice of reply, with hesitation and a hint of imperceptible distress in his tone.

"Highest authority, no matter the cost." Yang Kong pursed the corners of his mouth, the foundation of the No. 17 safety zone is insufficient, cannonballs are absolutely precious resources, at least the No. 17 safety zone has no ability to produce itself for the time being.

But so what? Times have changed, and the weapons of the former civilizations, although powerful, are no longer absolutely capable of dominating the battlefield.

Not even nuclear missiles! Times have changed – they have changed!

In this way, as long as you can hunt the third-level fierce beast on the screen, the red dragon lizard, no matter how much cannonballs are used, it will pay off.

The command in the sky immediately plunged the battlefield into a state of absolute tension, and countless combatants began to retreat, and the wire belt area immediately became extremely busy.

One by one, the warriors were pulled back to the Fortress of Hope by the steel cable, but they didn't know what was going on?

Of course, there is no need to know what is going on? On the battlefield, unconditional execution is the most important military quality.

The commander also stood aside honestly, and did not complain about snatching command in the sky.

Yangkong's status is very high, this is the first time that Tang Ling and the others have realized that this man who is raunchy and unpredictable for the first time and only pays attention to scientific research and flying dragons is extremely unusual.

Compared with others, it was obviously Tang Ling who was even more shocked.

Because he has third-level fierce beast meat, undoubtedly third-level fierce beast meat, the man called 'Kun' in the mysterious shop doesn't care about the third-level fierce beast meat thrown to him, the food for his little turtle...

Actually, it came from such a terrible guy?!

No wonder Leno wants to snatch!!

Everything was ready at this time, just waiting for the Purple Moon Warriors on a mission to dispatch.

What kind of battle will this be? Tang Ling actually forgot about his fear, and was more looking forward to it.

On the screen, the monster is still harvesting food, seemingly strolling around, just casually filling its stomach, but the direction it is moving is pointing directly at the Barrier of Hope.

And with the instinct of precision, Tang Ling began to calculate again, this monster is accelerating every second, very small acceleration, for example, the speed of the previous second is one meter, and the next second becomes an amplitude of 1.01 meters.

This made Tang Ling extremely sensitive, and he felt a certain purpose of the monster.

Almost involuntarily, he began to use his precise instinct to calculate the amplitude of the monster's facial muscle movements, this calculation was the first time, like a vague instinct guiding Tang Ling to come to a certain judgment.

And such a judgment has gradually taken shape almost in the next second.

The movement of the monster's facial muscles creates a 'vivid' expression, and the difference in amplitude betrays anticipation, nervousness, and excitement that cannot be concealed.

What is the result? Tang Ling himself is inexplicable, but it is really not outrageous, human beings have micro-expressions that can reveal their emotions, but fierce beasts don't?

He was inexplicable, why was he able to read some of the beast's 'thoughts' through his precise instinct?

Is this kind of cold number crunching to calculate emotional mood an interesting discovery?
