"Do you know the creatures in the cave?" they asked in unison.

Zhou You coughed lightly, "I know a little bit. I forgot which book I read it from. It seems to be a somewhat shabby novel biography. It describes the creatures in the cave as very cruel, and there are detailed inferences and descriptions."

"But I saw it a long time ago. I was young, and many things in the book were very effective. The descriptions of some scenes were just like what happened in real life. This made me feel that the novel was very special, so I remember it clearly."

"It's like what you just said, Principal Yang. The only other race I can think of is the cave creatures. Could this be true?"

Zhou You secretly thought that he had let the cat out of the bag and quickly tried to find a way to make up for it.

Principal Yang nodded seriously and asked, "Is the book still there?"

Zhou You shook his head as usual, "I don't know where it went a long time ago. You know I'm an orphan. The last time I saw this book was when I was a kid working as a stall keeper. I picked it up casually on the ground. I thought it was magical at the time, but I had already finished reading it. I was afraid that the book had an owner, so I put it back where it was."

"Alas, what a pity. It should be a good book. The author must be someone of some note." Principal Yang sighed and shook his head. "The author might be a mecha master or a frontline soldier who has experienced the creatures of the cave. It's possible that you have read this book, so you are lucky."

"That's right. The alien race I'm talking about is the cave creatures. These guys appear very strangely, and we still don't know where they came from or what their purpose is."

"But we only know that these cave creatures are very ferocious and like to eat humans and mecha ores. These two things are exactly what we humans cannot give in to, which makes the conflict between the two sides irreconcilable."

"Moreover, those who are not of our race must have different hearts. From all aspects, the battle between our two races can only end when one side is completely exterminated or the passage is closed!"

Principal Yang thought for a moment and continued, "The strength of these cave creatures is very strong, and because of the special characteristics of the mecha mine, our human race's weapons of mass destruction, weapons of destruction, and heavy weapons cannot enter unless they are carried by the mecha."

"This has led to the higher-ups attaching unprecedented importance to mechas, mecha masters, and military forces."

Principal Yang looked at the head teacher, Lao Li, and said, "Tell him what happened next. You've been down into the cave before, so you know more about it than I do."

"Old Li has also been down into the cave!" Zhou You was really surprised this time, "The cave should be very dangerous. Old Li, with our strength, wouldn't it be dangerous to go down there?"

The head teacher, Old Li, gave Zhou You a blank look and said, "Are you looking down on my strength? You look down on me and say that the caves are dangerous, but not all caves are dangerous. There are different levels of danger."

"Take you for example. Your mecha is powerful, but your fists and feet are still pinned to the ground by me. No matter how powerful your mecha is, it is not as powerful as the Lord of Luo City!"

Zhou You smiled apologetically but didn't dare to say anything. It was obvious that Lao Li was taking revenge on him. He insulted him with his words. He was too petty.

The head teacher, Lao Li, did not say anything more and turned to the main topic. "Our human race has different strengths and strengths, and the cave creatures are naturally the same. Some caves are big, some are small. The environment in some caves is more suitable for cold-resistant mechas, and the environment in some caves is more suitable for heat-resistant mechas. They are all different."

"Although my strength is far from reaching the level of entering a large cave, I can still enter some small caves without any problem. Relatively speaking, the environment of a small cave is more like the environment of our Blue Planet. It is generally normal, not particularly hot or cold, and the climate is also very stable."

The class teacher, Lao Li, spoke with emotion about some of his heroic deeds, most of which were about how he killed the cave creatures and how he displayed his divine power. Then he changed the subject, "In this way, we took over a small cave, and all the powerful cave creatures inside were killed. Only a few were left, which posed no threat at all. Their strength was probably C-level or below."

"At this time, someone had an idea. Why can't we let our own people go into the cave to train? After all, it's far better to see the real thing than to just talk about it. Even if you practice well in the simulation field, it's still not as good as coming to the cave to experience it in person."

"This person's proposal was quickly passed unanimously. Besides, the small caves are not empty except for the cave creatures. The resources in the caves are very rich, and many of them are unique to the caves. We don't have them in the Blue Star world."

"Some of these resources are very tough, while others are extremely hard. In short, they are all materials that can be used in mechas, and they are also of great help to our basic industries. Many scientists even say that the exploration of the underground caves will be the time for the next technological change of our human race!"

"The caves at this time are full of treasures. Once you go down, you can get equipment, secret manuals, parts, materials, and all kinds of resources. Basically, they are all useful as long as you bring them up. But we can't let the mecha masters dig for these things. Not to mention that there are so many resources that they can't be taken away, just searching and transporting them will be a meaningless waste of the mecha masters' resources."

"It would be even more unreasonable if ordinary people were to take it. Although there are no powerful cave creatures, C-level can kill countless ordinary people. Taking this aspect into consideration, it can be used to hone the students of the mecha department, killing two birds with one stone. It's really great."

Principal Yang continued, "In Luocheng, since Lao Li had been there, he brought back these first-hand information to share. The principals of Luocheng No. 1 Middle School, Luocheng No. 2 Middle School, and Luocheng No. 3 Middle School immediately decided to change the nature of the school and directly turn it into a mecha school. They also spent all their money and a lot of financial support to buy dozens of C-class mechas of that year for students and teachers to use."

"Los Angeles No. 1, No. 2, and No. 3 Middle Schools transformed quickly and completed all of this in just one week. Then, the teacher led the first group of students into the small cave to explore."
