I’m A Wasteland Giant

　　 "If a cockroach is enlarged 100 times in the same proportion, what will happen?"

　　 On the podium, the thin-haired teacher looked at the classroom with piercing eyes, wanting to see what the students underneath were saying.

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

　　 "Hahaha..."

　　 suddenly caused a roar of laughter among the students in the class.

　　 After listening to the kind-faced teacher, he was not angry. He laughed for a while, nodded and said, "This is a cockroach that has replaced your thoughts. Okay, who else has any other thoughts?"

　　 "The cockroach has grown a hundred times bigger, and it is a few meters tall. I think a chicken is definitely not enough to eat!"

　　 The students laughed again.

　　 Teacher nodded and smiled: "Yes, continue!"

　　 "When the body of a 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, but it becomes larger in proportion, and the skeleton can definitely support gravity!"

　　 "……"

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

　　 While he was talking, he started to write the formula with chalk on the blackboard.

　　 "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 living things grow linearly, and this relationship is determined by the square-cube law."

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

　　 Du just got lost when he heard this. To be precise, he put his spirit 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, you can pick up the stars and swallow the moon and grow to the size of a planet...

　　 Below this description is a property panel.

　　 The position on the first line, called the foundation of the first-order ancient god, has been smoothly lit. In the square brackets behind it, there is a series of dim remarks: (The source energy required to upgrade is 10,000 points.)

　　 "The foundation of the ancient gods?"

　　 Almost when Du Gang thought about it, a stream of information emerged directly.

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

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

　　 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 line are all bleak. Du Gang understands that this is the reason why it has not been lit.

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

　　 At the same time, there is a faint feeling in his heart that as long as he wants to, he can transform into a ‘giant’ now.

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

　　 At this time, the biology teacher is still teaching.

　　 "If this cockroach weighs only one gram and its volume is 1×1×1=1cm---3, then it only needs to bear 1 gram of weight per square centimeter of its cross-section."

"After magnifying it a hundred times, the volume becomes 100×100×100=1000000cm3. If the density does not change, then its weight will increase to 1000000 grams, although its cross-sectional area has also increased accordingly. But it only increased to 10,000 cm2. What does this mean? It means that the weight per square centimeter of the cross section has increased by a hundred times!"

　　 "So, if this cockroach expands a hundred times, it will soon be crushed to death by its own weight!"

　　 Hearing this, Du Gang frowned and raised his hand to ask: "Teacher, how can he survive when he grows larger?"

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

　　 "I said that it will be crushed by its own weight. It is only the influence of the exercise system on it. In addition, the influence of other systems on it..."

　　 "According to the square-cube law, as cockroaches grow larger, the oxygen they need also greatly increases. The increase in the surface area of ​​the gas exchange part cannot keep up with the increase in volume..."

　　 "So, on the earth, if a cockroach grows a hundred times in size, in addition to being crushed to death, he will also die from lack of oxygen..."

　　 Immediately afterwards, the teacher wrote the words "respiratory system".

　　 Du Gang was stunned, and subconsciously muttered, "Is there a way to solve the hypoxia problem?"

　　 Teacher found him fascinated, very pleased, UU reading www.uukanshu. com nodded and said, "It's not impossible. If this cockroach adds more trachea and expands the amount of oxygen it can absorb, it can survive..."

　　 "In addition, if the oxygen content 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 huge. One of the reasons for this may be that the oxygen content in the atmosphere is very high..."

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

Mr. 　　 narrowed his eyes and smiled and said: "If you don’t consider the problem of oxygen poisoning, and you happen to be in the developmental stage and the oxygen content is increasing, 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 higher than animals!"

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

　　 At this point, the teacher spread his hands and said with a smile: "Students, today's class will end here, next class, we will talk about the reproductive system and the urinary system..."

　　 "The reproductive system...hehehe..." The students in the audience all snickered with red ears.

　　 "Here, let me say one more question, what are germ cells?"

　　 "After students go back, please check the textbook and learn about germ cells. I will ask another interesting question for everyone to answer in the next class..."

　　 "Okay, get out of class is over!"

　　 The students stood up and bowed: "Goodbye teacher!"

　　 Teacher nodded, turned and left the classroom.

　　 Not long after the teacher left the classroom, a student suddenly yelled, "Look at the headlines on the phone!"
