It took the two of them another half an hour to return to the protective car, and after arriving at the protective car, they asked General Kerry to find out that they had already returned once and sent some energy liquid, and now they went forward for the second time.

General Kerry asks Professor Jerry how he is looking for metal minerals, and Professor Jerry tells General Kerry that he has found it, but he doesn't have a refining instrument, so he needs to make a device now.

"You are all big scientists, and a small refining instrument should be difficult for you." General Kerry smiled slightly, and then said.

"Scientists aren't omnipotent." Professor Jerry smiled helplessly at General Kerry.

General Kerry smiled wryly, pointed not far away, and said, "They're back." ”

Professor Jerry saw Lovansy and they were back with the energy liquid.

I have to say that the efficiency of several of them is quite fast.

When Lovansey returned, he saw that Professor Jerry had returned, and thought that something important had been done.

"Did you find it?" Lovansi asked.

"I found it, but I couldn't purify it." Jerome shook his head helplessly.

Lo Van Xi frowned and looked over to Professor Jerry.

"We've already discussed it, and we need to make a refining instrument by hand." Ian glanced at Lovanashi.

Lovansi nodded slightly when she heard this.

"That's all the way it is."

"Datelem, you go look in the van and see if you can find a small engine, and the metal wire detector, and some of the things you need for a metal extractinator." Professor Jerry said.

When Dytelem heard this, he nodded, and walked directly towards the protective car.

I came to the protective car, and after some searching, I barely found the thing.

In fact, the most important thing is the engine, otherwise it would not work.

"Now that Captain Dai has found all the things for us, let's get to work." Professor Jerry looked over to everyone.

Everyone nodded.

Everyone is ready at this time.

Under Professor Jerry's arrangement, everyone has a job.

It took everyone three days to make the metal extractor, and within three days, most of the food brought was eaten.

"Now that more than half of the food has been eaten, there is still a long way to go, so everyone should save some food in the future." Professor Jerry looked at everyone with a serious face.

Everyone looked at Professor Jerry's serious face and nodded slightly.

"Okay, let's get ready to get started, the source of the metal vein has been found, let's go with me now, General Liukeri is here alone to watch the protective vehicle." Professor Jerry said to everyone.

Everyone nodded, pushing the metal refining instrument and walking straight ahead.

In order to save energy, they are reluctant to use energy, and they just push forward all the way, anyway, it is a flat road, and it is not far, so it is considered to be exercise.

"In fact, the operation function of the metal extractor does not use much energy to start, so it is better to start the switch and let the refining instrument run by itself." Lovansi said.

"Although the energy liquid seems to be a lot now, there are still a lot of roads after us, so let's save some, the road is not far, just about a kilometer, and the road is relatively smooth." Professor Jerry said with a slight smile.

Professor Jerry said so, and Lovansey nodded.

The group pushed the instrument slowly and leisurely forward.

Although the instrument is not heavy, it is also hundreds of catties, which is the hard work of several people for three days.

And whether it can be put into use or not, I don't know, only after trying it.

Between the mountains, everyone stopped together, looking calmly at a smooth wall stone in front of them.

"This is it." Professor Jerry said, pointing to the wallstone.

Lovansi nodded.

"The wall stone has been detected by metal instruments, and it should be the composition of tungsten, which is somewhat fragile and may not be suitable for the use of the wall of the protective vehicle." Lovansey pointed out.

"Fanxi, you're right, the results of our detection are the same, but mine is a deep detection, and I have detected that there are metals such as sodium gold, black silver, and King Kong No. 1 at a depth of ten meters on the stone wall, all of which we need." Professor Jerry said.

With Professor Jerry's words, Detelem was much more relieved.

"Now that Professor Jerry has explored the depths, it couldn't be better." Lovansi nodded slightly.

After the energy source is poured into the metal refining instrument, the metal refining instrument emits a humming sound.

If the Metal Refiners weren't able to exert their unique abilities, then they would really have to go home this time.

The protective vehicle is seriously damaged, and this matter must be done as well as possible.

"Hopefully this time it will go a little bit smoother." Professor Jerry said.

The Refiner made a buzzing sound, and as it walked forward, some of the gravel on one side was directly turned into ashes by the powerful agitation force in the Refiner.

The refiner took small steps and went directly into the stone wall, and then it got deeper and deeper, and opened a small opening in the stone wall, like a small door.

It had been more than half an hour since the extractinator entered the stone wall, and Professor Jerry looked at them with a blank eye, hoping to make good progress.

However, it has to be said that progress is still very slow.

In the blink of an eye, three hours have passed, and the extractinator still has no intention of coming out, which really makes Professor Jerry very anxious.

The efficiency of the refining instrument is somewhat small, only 3 kilowatts, so it works very slowly.

If it could have 10,000 watts, it would work faster, but the engines that can be found now are only 3 kilowatts.

I have to say that the country of Kem is really a little backward.

For Professor Jerry, 3 kilowatts is just enough for the working speed of the refining instrument, and whether it can be successfully refined is not certain.

But Professor Jerry is confident that there will be a good outcome.

Everyone waited for six hours, and at this time, the sky was already a little dark, but in this place, in addition to the extreme cold, the sky seemed to be darker and slower.

Buzz!

When the refining cart came out of the path in the stone wall, everyone stared at the refining cart one by one.

Everyone stared at the refining car as if they were staring at a treasure.

"Come, how about the results?" Lovansey strode over.

Several people gathered around and looked at it carefully, and some of the various metals in the refining instrument were refined, but if you look at this amount, it is still far from enough.

"That's not enough, you can repair about 10 percent at most." Lovansi said.

"In this case, let the refining instruments continue to work, Jerome and Lovansi, you two will go back with these metals to repair them first, and we will send them to you here every four hours." Professor Jerry made the arrangements.

Now this can only be the case, so when Professor Jerry said this, Lovansi and Jerome nodded directly.

The reason why Professor Jerry let the two go back was that Professor Jerry knew that the two were highly skilled and could repair the protective car as soon as possible.

Lovansi and Jerome carried the metal extract in a cloth bag and went straight back.

And Professor Jerry and Datrime, Andrew, Ian continue to wait here.

Every four hours, Andrew and Ian would return with the newly extracted metal.

The round trip has been carried out countless times.

By the fifth day, the repair was almost done.

"Andrew, you and Ian will bring back the refining instrument this time, you don't have to come back." Professor Jerry looked at Andrew with a smile on his face.

"Okay." Andrew nodded.

"Professor Jerry, aren't you going back?" Ian looked at Professor Jerry in confusion.

"I'll go into this little hole in a moment and see if there's anything else in there." Professor Jerry said.

"Anyway, it's almost repaired, Professor Jerry, why do you bother to look inside?" Andrew asked, puzzled.

"I'm just curious, I want to see what it's like inside, the extractinator just split a small passage, I stopped by to take a look." Professor Jerry said.

The two nodded, didn't say anything more, and went straight to the way they came.

The refining instrument was only the size of a human figure, and when Andrew and the others went back with the refining instrument, Lovansey and Jerome did not see Professor Jerry returning, so they couldn't help but ask again.

Andrew told them why.

"Professor Jerry is just curious, at such an old age, he is still like a child, and he remains curious." Jerome shook his head helplessly.

"Didn't Dytram come back too?"

"With Professor Jerry."

Dietlem looked at the dark depths of the cave in front of him, although he could see clearly from the outside for nearly ten meters, because of the sunlight, but the light could not enter the depths.

"Are we really going in?" Dietlem looked over to Professor Jerry.

"You can wait outside, I always feel like there must be something else in here, I'm curious." Professor Jerry said.

"If you want to enter, let's go in together." Detlem said.

"It's just that this entrance is very narrow, and the two of us are just big enough to get in, and we have to keep our heads down." Professor Jerry said.

Both of them are relatively thin, and if they were fatter, they would not be able to get in at all like General Kerry.

Professor Jerry strode in, and then Professor Jerry became a little nervous, because in the depths of the cave, there was a whining sound, and when he heard it, it was like a child crying.

"There's a voice in there, do you hear that?" Professor Jerry said softly.

Naturally, it was for Detrime behind him.

Dytelem shook his head, he really didn't hear.

Maybe the whining voice was too quiet, and Professor Jerry walked in front of him, and his whole body took up the space, so Dytelem couldn't hear it.

"Be careful, too." Professor Jerry reminded.

As he spoke, Professor Jerry cautiously walked forward.

The farther he walked forward, the slower Professor Jerry walked.

"The hole made by this extractor is really deep, and we have walked twenty or thirty meters." Detrium said behind Professor Jerry's back.

"Hmm." Professor Jerry nodded slightly.
