Regarding the situation of no iron and no coal in this world, Jiao Ming made a lot of guesses in the three days of prospecting, but he felt that none of them were reliable. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 Info noticed the strangeness of 8,000 meters underground this time, and couldn't help but think of a conjecture that had been denied again: the theory that civilization ran out of resources last season.

The only flaw in this conjecture is where did the disappeared civilization get the metal from the previous season?

It doesn't make sense to make a spaceship into outer space, assuming that the outer space space of this planet is similar to that of the earth, then you can directly collect ores on an asteroid in outer space, and complete all the steps until you make a spaceship, why waste a process of launching and launching into space.

Since it's not in the sky, it's underground, and it's likely that the civilization in the last season built some bunker ruins underground after collecting all the metal ores, coal and oil on the surface, and used all the steel resources at hand there.

... Do you remember my secret recipe for curing all diseases? Forget? Oh, at what age did you start to suffer from Alzheimer's, let me think about the cure for Alzheimer's...

... I don't care about you!... Jiao Ming scolded unceremoniously, and then entered the state of communication with the Qi Demon Medium again to block a certain system. Just finished the extreme exploration, but he couldn't even rest for a while, Jiao Ming scratched his head and was distressed, it seemed that he still had to take Xiaoshi with him.

Jiao Ming came to the edge of the pit bored, admiring the destructive power of the crocodile duke, and at the same time, he also wanted to see the operation of the cement furnace. On the east side of the pit wall is a row of shacks, which are supposed to be the quarters of the coolies. There was a big pit at the end of the shack, and Jiao Ming soon knew the purpose of this big pit, and then he slandered: The toilets are all gone, so you can't build a shed to cover it.

On the west side of the pit wall are two cement kilns, which are rotated to improve efficiency because the kilns can only be cooled naturally. A group of coolies were moving things from one furnace to another, while Binglian and her five apprentices were surrounding the other kiln, looking like they were still talking from a distance, thinking that the work was not hard.

The bottom of the pit was shaped like a shallow plate, about 50 meters in diameter, and Jiao Ming noticed that although the coolies were freehanded, they did not affect their work at all, because the bottom of the pit was full of broken stones, and the largest was only the size of a watermelon. After thinking about it for a while, he thought of the only possibility: when the crocodile duke opened the mountain, he used the earth to shatter the rock formations below, and then Jiao Ming was a little frightened.

Soon after, the six Binglian returned to the shed and continued the class, Jiao Ming took advantage of the gap in the explanation to ask if the chemical knowledge was useful, and this morning he talked about the introduction to the periodic table and the combustion reaction of carbon.

"Amazing match, I even guess your chemists there are all fire magicians. Binglian said with a smile.

"Then I'll skip and talk. Jiao Ming pulled out a sheet from the middle of the manuscript, which was the silicate part related to cement. This is much more complicated than the combustion of carbon, and even involves some knowledge of acidity and alkalinity, but fortunately, the acceptance ability of the five people is not bad, after all, it is also 'carefully selected' by Ms. Ziyu.

But Binglian frowned tightly, and couldn't see how much she understood. Lunch was settled in the shed, and then he continued to work without even a lunch break, and the afternoon was as busy as the morning, and it was not until the way back to the castle that Jiao Ming had the opportunity to ask the reason for Binglian's frowning.

"I wasn't stupid enough to not understand, I just remembered something about the Academy of Magic. Binglian was sitting behind Jiao Ming at this time, Jiao Ming couldn't see her expression, but listening to the voice, she didn't have the depressed mood during the day.

"Let the past pass. Jiao Ming comforted.

"I'm thinking about the future. ”

"Huh?"

"Do you know about the Wizards' Association deepening their education and opening a high-level magic academy?"

"I've already heard from Ms. Ziyu, why don't you want to go?" In Jiao Ming's opinion, Binglian's quota was certain, thinking that Binglian had mentioned her unpleasant study abroad experience, and then asked, "Wouldn't it be those old classmates who are afraid of seeing you?"

"They don't deserve it yet!" Ice Lotus's voice was cold.

"Why is that?"

"It's just that I feel a little emotional, just thinking that I've become like them. ”

"Proton!?" Jiao Ming blurted out, and then bluntly changed the subject: "Ahem...... Let's talk about something else, what the hell, I found something strange in the ground, tell you about it?"

When the crocodile leader was at war with the Xuqin people, the crocodile family gathered the children of the nobles in the territory and put them in the rear, which meant that it was self-evident. And this time, when the United Kingdom and the Evsen religious state were in war, the crocodile family also had to 'deposit' the ice lotus, which was really a feng shui turn.

"That's the case, you don't have to shy away from it, I'm so stingy in your eyes?" Bing Lian said and pushed her elbow against Jiao Ming's back, faintly threatening.

"Of course not. Jiao Ming replied categorically.

Binglian chuckled and said, "But it's not bad to listen to strange things underground." ”

Jiao Ming hurriedly told the story of encountering something strange eight thousand meters underground that blocked the spatial transmission magic, and said that this thing might not only be as large as the cement kiln to Changteng Town.

"It's nothing. Binglian didn't care, the matter of eight thousand meters underground was too far away.

"Hehe, then I'll talk about something more exciting. Jiao Ming said his conjecture about the civilization of the previous season.

"You mean there may be metal in this thing deep in the earth?" Ice Lotus finally calmed down this time, metal is too scarce in this world.

"I just think it's worth a try, and no one knows what will happen after breaking through the interference and blockage. Jiao Ming shrugged.

"Gotta give it a try!" Bing Lian's tone was as firm as if she wanted to enter Dang. "If there's metal, everything will be solved! Do you have any way to get through the barrier now?"

"Take it easy, last season's civilization was all speculation, don't you take it seriously? ”

"Don't change the topic, talk about it quickly!" Binglian was really anxious this time, and used her elbow to top it again, and Jiao Ming was so pushed that he almost fell on the bull's head of the hammer.

"Nope. Jiao Ming smiled bitterly and rubbed his back hand. "I've been thinking about it for a hundred days, but I can't think of a way. ”

"What about the magic addiction potion?" Ice Lotus clapped her hands.

"I know how I feel after drinking the potion of addiction, it shouldn't be of much use. "Jiao Ming is not optimistic about doping.

"If it's a man-made thing, it will always be damaged over time, will there be a crack somewhere or something?"

"No, I can't. Jiao Ming thought for a moment and then denied it: "A big crack will definitely lead to a collapse, and the opposite is a big crack that does not damage the structure." So let's assume that the crack is within one person's width and one person's height, and such a size may leak a few steps away, should we try it every three or five steps?"

Although Jiao Ming didn't know what was underneath, he took the earth's viaducts and high-rise buildings as a reference, and the crack was already quite ferocious.
