I’m A Wasteland Giant

If you scale up a cockroach a hundred times, what will happen?

On the podium, the teacher with thinning hair looked at the classroom with piercing eyes, wanting to read the speeches of the students below.

It will steal chicken! Almost as soon as the professor finished speaking, such a voice came from the corner of the classroom.

Hahaha……

It immediately caused the students in the class to burst into laughter.

The teacher with a kind face didn't get angry after hearing this. He smiled for a while, nodded and said, This is to substitute your thoughts into cockroaches. That's ok. Does anyone have any other ideas?

The cockroach has become a hundred times bigger, and it is several meters high. I think it must not be enough for a chicken!

The students laughed again.

The teacher nodded and said with a smile, Yes, continue!

As the size of the cockroach becomes larger, the gravity it bears will also increase. I think it may be crushed to death by gravity!

That's not necessarily true. It's scaled up proportionally. The skeleton can definitely withstand gravity!

...

The teacher was very pleased to see the students who were actively speaking at the bottom, and said: There is a concept in biology called 'allometric growth relationship', which refers to the relationship between biological characteristics such as behavior, shape, and required energy, and body size. There is a quantitative relationship between them, that is to say, organisms will change quantitatively as the size of the organism changes, but this change is not proportional!

As he spoke, he began to write formulas on the blackboard with chalk.

This concept was first proposed by Julian Huxley in 1932. Here, it can be expressed by a mathematical formula: E=70M^3/4

The shape and size of creatures grow linearly, and this relationship is determined by the square-cube law.

That is, when the length of an organism is doubled, then its surface area will be quadrupled, and its volume and mass will be eight times the original...

Du just lost his mind when he heard this. To be precise, he put his mind on a virtual panel that suddenly appeared in his mind.

【Du Gang】

[first-order ancient god]

Ancient God, a species that can grow and grow infinitely!

Theoretically, as long as the energy is enough, it can pick up the stars and devour the moon, and grow to be comparable to the size of a planet...

Below this description is a properties panel.

The position on the first line, called the first-order ancient god foundation, has been successfully lit up, and there is a series of dim notes in the square brackets behind it: (10,000 points of source energy are required for the upgrade.)

The foundation of the ancient gods?

Almost when Du Gang was thinking about this, a stream of information emerged directly.

The foundation of the growth of the ancient gods, the upper limit of the first level is ten meters in height, which can ignore the negative effects of the human body system after transformation. The current available time per day: ten minutes.

[After the first level is completed, the transformation time limit will be lifted]

The attribute panel is more like a skill tree. The top one is the foundation of the ancient gods, and below it, in the second row, there are a total of eight branches.

Nervous system, motor system, circulatory system, respiratory system, digestive system, endocrine system, urinary system, reproductive system.

At this moment, the eight branches of the second row are all in a bleak state. Du Gang understands that this is the reason why they are not lit up.

And behind each branch, there is a note: (Activation requires 100 points of source energy.)

At the same time, he had a faint feeling in his heart that as long as he wanted to, he could transform into a 'giant' now.

However, he resisted the urge and did not dare to try it in the classroom, but opened his eyes.

At this time, the biology teacher was still giving lectures.

If the weight of this cockroach is only one gram, and the volume is 1 x 1 x 1 = 1 cm, then on its cross-section per square centimeter, it only needs to bear 1 gram of weight.

After it is enlarged one hundred times, its volume becomes 100×100×100=1000000cm. If the density does not change, then its weight increases to 1000000 grams, although its cross-sectional area also increases accordingly. But it has only increased to 10,000cm, what does this mean? It means that the weight required to bear the cross-section per square centimeter has increased by a hundred times!

So, if this cockroach were to expand a hundred times, it would soon be crushed to death by its own weight!

Hearing this, Du Gang frowned, raised his hand and asked, Teacher, how can he survive after becoming bigger?

The teacher smiled and wrote four words on the blackboard: motor system.

I said that it will be crushed to death by its own weight. It is only the influence of the motor system on it. In addition, the influence of other systems on it must be added...

According to the square-cubic law, as the cockroach grows larger, the oxygen it needs also increases significantly. The increase in the surface area of ​​the gas exchange site cannot keep up with the increase in volume...

So, on Earth, if a cockroach grows a hundred times its size, besides being crushed to death, it will also die from lack of oxygen...

Immediately afterwards, the teacher wrote down the four words respiratory system.

Du Gang was stunned, and subconsciously murmured: Is there a solution to the hypoxia problem?

The teacher was very relieved to find that he was fascinated, nodded and said: It's not impossible, if this cockroach adds more trachea and expands the amount of oxygen it absorbs, it can survive...

In addition, if the oxygen content contained in the earth's air rises, it can also provide it with more vitality...

Scientists have discovered that in the age of dinosaurs, creatures were very large. One of the reasons for this may be that the oxygen content in the atmosphere is very high...

At this time, some other students asked: Teacher, if our current oxygen content becomes higher, can I still grow taller?

The teacher narrowed his eyes and said with a smile on his face: If you don't consider the problem of oxygen poisoning, and you happen to be still in the development stage, and the oxygen content increases, then it is indeed possible for you to grow taller under the influence of this environment...

In this environment, plants will grow faster, bigger and taller than animals!

Of course, in this oxygen-enriched environment, our next generation will be taller and bigger!

Speaking of this, the teacher spread his hands and said with a smile: Students, this is the end of today's class. In the next class, we will talk about the reproductive system and urinary system...

Reproductive system...hehehe... The students in the audience all laughed with red faces.

Here, let me ask another question, what are germ cells?

Students, after you go back, please check your textbooks to learn about reproductive cells. I will ask another interesting question for everyone to answer in the next class...

Okay, get out of class is over!

The students immediately stood up and bowed: Goodbye, teacher!

The teacher nodded, turned and left the classroom.

Not long after the teacher left the classroom, a student suddenly shouted: Look at the headlines on your phone!
