This is still based on the fact that the system has no limitations, and Shi Qiang and others have ordered many sharp logging tools from the earth. www.biquge.infoOtherwise, like the previous conditions, without these sharp knives and saws, it would not be possible to form mass manufacturing at all.

Thirty bronze spears were driven out, six meters long, and a man could hold his feet to stab the enemy who climbed up the animal pen.

It was clear that the weapons were prepared to deal with the enemy who climbed the enclosure.

On the fifteenth day, that is, half a month after Li Hang came here, the cooldown time of the teleportation array this time has been reduced by half, that is to say, only half a month later, Li Hang can teleport back to Earth and find greater fire support.

Li Hang has secretly decided that as soon as the half month has passed, he will go back this time, and he will have to get more guns and artillery no matter what, otherwise, it will be too slow to turn the passive into the active to fight this yellow sand desert and slowly develop on his own territory alone.

However, under this premise, he will need to survive another fifteen years before he can do it, but will the seemingly peaceful days now really remain calm? No one will believe this.

continued to stick to this strange planet for a few days, but Li Nan suddenly came to report that the giant ants that were captured a few days ago now have made new discoveries.

When Li Hang arrived, he found that Li Dong and several others had gathered around the animal pen built for the two giant ants, this special animal pen circle is not large, only ten meters in diameter, that is, one hundred square meters, and was built in a corner of the castle square.

Now the two giant ants imprisoned inside are looking down and nibbling on some "food".

"They're finally eating?" Li Hang didn't know the specific situation, and when he saw it, he said strangely, you must know that since he caught this giant ant, they haven't eaten for many days.

The beast slaves tried their best, but the two giant ants ate nothing, and according to this unintelligent ant creature that only survives on instinct, everyone has not been able to understand why they would rather endure hunger than eat anything.

You know, ant life does not have its own independent thinking, how can they subconsciously go on a hunger strike?

"Yes, master, they finally opened their mouths to eat, but what they ate was not ordinary food, you take a closer look......" Li Xi said with a wry smile on his face, pointing to the two giant ants who were eating with their heads down.

Li Hang looked at it again, and gradually the curiosity on his face froze, what? What are they eating? If Li Hang felt that he was not dazzled, these two giant ants seemed to be gnawing on a piece of ore?

"The new discovery you're talking about is that they only eat metal?" Li Hang was surprised and said that these iron ores were the most primitive ores.

It was mainly cleaned up in the underground excavation in order to arrange the planetary shelter before, and Li Hang couldn't use it originally, but now he didn't expect it to be for the food of the giant ants.

"Yes, they don't eat anything but ore, and we just collected their excrement, which is a puddle of warm molten iron that hasn't solidified, master." Li Nan pointed to a puddle of molten iron on the ground that had not yet cooled and solidified.

Li Hang hurriedly squatted down, picked a branch and stirred it a few times, but did not find any unpleasant smell of excrement, which was full of metallic smell.

Li Nan is right, this is indeed a puddle of molten iron that is still in the future and solidified.

"Eat only metal...... The excrement is molten iron...... Mah, I know......" Li Hang muttered softly, and then his eyes lit up, he seemed to think of something.

After all, I understood why the green bull monsters would rather risk death and injury to catch these giant ants.

"You go and find Shi Qiang and a few of them."

When the three of them rushed over, the molten iron, which had not yet solidified, had gradually cooled and solidified into an irregular discus.

"Is this piece of iron slag really excreted by them?" Hou Cheng had been refining steel in a steel mill, so he was also a little worried about this aspect, and he repeatedly touched this piece of iron slag, looking a little surprised and muttering to himself.

"What's wrong? Is there anything magical about this discus? Angela asked quietly.

"It's not magical, but it's magical, you know, this piece of iron slag is not an ordinary molten iron solid." Hou Cheng lowered his head and continued to study.

"Oh? How is it not ordinary? ”

"It's like pig iron that has been refined once, and it's hard to imagine that this piece of iron slag could be the product of a monster that has just been excreted."

After Hou Cheng simply popularized the knowledge about this aspect, everyone understood.

To be precise, this piece of iron slag is not a big deal, because it is very common on the earth, and there are many of them.

But when examined carefully, it is remarkable, for its iron purity is like that of treated pig iron, and in short, this unformed substance does not need to be calcined at all, but only condensed into an iron tool.

So the strength of this iron tool is almost the same as the strength of an iron tool made of wrought iron, Li Hang is not familiar with this knowledge, but it does not prevent him from understanding what Hou Cheng is referring to.

"In other words, it can be made directly into iron tools, or even weapons?" Li Hang said tentatively.

"Yes, if carbon is added again, then it will be easy to make steel, and then after repeated calcining, it can even be further calcined into 100 steels, boss, you say it is not mysterious." Hou Cheng said excitedly, but his eyes fell on the two giant ants who were still eating with their heads down.

"I see, no wonder these green bull monsters have a blunt iron weapon, and no wonder they go around hunting these giant ants!" Li Hang's heart suddenly felt like a mirror.

He didn't expect that many creatures on this planet actually had such a magical giant ant, which could be made into a batch of iron tools with good strength just from excrement.

Knowing this, Li Hang's mind suddenly broadened, do these giant ants only excrete the strength excrement of wrought iron when they eat iron ore, or do they excrete targeted molten metal iron after eating all metal ores?

If it's the latter, then I'll go!

Li Hang didn't dare to think about it anymore, he had always had to know that he had been constantly moving materials from the earth to support the mission of conquering the world here, but now this discovery meant that he could use the natural minerals of this planet to feed back his foundation on the earth.

As long as he thought of this, Li Hang couldn't suppress the excitement in his heart, a whole planet, a planet's resources.

Despite the barren surface, who can be sure that the mineral resources underneath are not abundant? Often, on the contrary, it is precisely because the resources of this planet have not yet been exploited that the resources contained under the surface of the planet may be even more amazing, right?
