"What problem?" Lu Cheng couldn't help asking.

Ma Ben was pondering for a moment, and said:

"First of all, if you want to transform Qi into an energy cannon that can blow down a small mountain, you have great requirements for refining materials!"

"It's not just that you need to provide it!"

"Just like those strangers who want to use their innate powers, they have to cooperate with the methods of various schools and schools!"

"As a refining master, the material for refining is our technique!"

"If you want to preserve the essence of the innate qi, and then transform the innate qi into a more powerful energy, you need very special materials."

"As far as I know, only Qinglong Mine can roughly meet the demand in the world!"

Listening to Ma Benzai's explanation, Lu Cheng's mind began to search for information about the Qinglong Mine.

Soon, he knew what the Qinglong Mine was about.

This is an extremely rare ore!

The Qinglong mine grows near the volcano. Because it is grilled by high temperature all the year round, this Qinglong mine has a special attribute.

Easily absorb congenital qi!

And it can transform the absorbed congenital qi and magnify it several times!

Many top magical artifacts, including Qinglong Mine.

The Qinglong Mine is not only flexible, but also exceptionally strong, suitable for making large magical artifacts.

It is indeed the only material for making Gundam!

However, it also has a disadvantage.

That's less!

It's so pitiful.

Back then, after many refiners knew the special features of this Qinglong Mine, they used special methods to exploit them.

By now, there are very few known Qinglong mines in the world!

"This is indeed a problem." Lu Cheng held his cheeks.

When he conceived the concept of Gundam before, although he also considered the issue of materials, he did not expect that the materials needed would be so special!

Although, the use of other materials can also be made up, but the performance and power, I am afraid it will be reduced by several grades.

It can only make a high shell, unable to play its original effect.

"Ben, do you know where to find the Qinglong Mine?" Lu Cheng asked directly.

Ma Ben groaned for a while and said:

"Now, due to changes in the environment, it is getting harder and harder to find Qinglong Mine."

"I heard from the clan a few years ago that a new volcano appeared in the area of ​​Tengchong, and a new Qinglong mine appeared there."

"However, the clan seems to have searched for it several times, but didn't find it!"

Tengchong...that is in Yunnan.

It is about 800 kilometers away from the mountain city.

If you drive a car, it will only take two or three days.

It just so happens that he has an old car in his family.

It was still a few years ago when Lu Shouyi ambushed the spoils captured by a group of devil soldiers.

However, no one in the family can drive a car, so it can only be left in the warehouse to eat ashes!

Thought of this.

Lu Cheng felt a bit fiery in his heart, and said:

"It's here, why don't we look for it and try our luck?"

"I happen to have a car, and I can drive there directly."

If you don't hurry up, God knows if you will be caught up quickly.

Ma Ben opened his mouth and said:

"Brother Lu, don't worry, I haven't finished talking yet."

Lu Cheng opened the mouth and said:

"What do you say."

Ma Ben was here with his hands behind his back, pacing as he said:

"Even if the Qinglong Mine is successfully found, there are still two problems to be solved."

"First, there needs to be materials that can be used for the Keqimen Dunjia to form a sensor system so that Gundam can follow the human body."

"Second, there needs to be materials that can accommodate the spirit in order to establish an effective connection between the body and the Gundam."

Lu Cheng raised his eyebrows.

After Ma Benzai reminded him, it was really difficult to make a Gundam.

What he thought before was still a bit too ideal.

Now, there are three problems before him!

The first problem is to make the main material of Gundam, the Qinglong Mine is very rare and hard to find.

The second problem, Gundam's internal control compartment, must have materials that can engrave the Qimen Dunjia.

The third problem is that for some key parts of Gundam, special materials that can hold the spirit have to be added to achieve efficient connection.

Otherwise, only a sensor system will not be able to control the Gundam normally!

"It really doesn't work, you can control it manually, but the operability and flexibility will be greatly reduced." Lu Cheng pondered.

After all, with manual control, it is inevitable that there will be delays or freezes.

Can't do it like an arm.

Moreover, it will be very difficult to get started!

After all, in this era, there are not many who can drive. Do you expect these people to drive Gundam?

Ma Ben opened his mouth and said:

"I remember that in the back mountain of Wudang, there seems to be a stone that can burn Qimen Dunjia, but it's not easy to get it."

"As for the refining materials that contain the spirit, they are much easier to find than the Qinglong Mine. Many refining materials are available."

Lu Cheng opened the mouth and said:

"These two issues can be considered later, first find the Qinglong Mine."

After finding the Qinglong Mine, you can make the main model of Gundam!

At that time, if it doesn't work, you can directly control it manually, and it will be a big killer!

Ma Ben was rubbing his hands:

"If you can really find the Qinglong Mine, and then use my self-cultivation furnace to transform it, the power can be improved a lot."

Ma Benzai's self-cultivation furnace is indeed a special magic weapon!

The finished product can be produced quickly.

Kind of similar to a 3D printer.

Moreover, through the special device on it, the material can be refined into a magic weapon by means of refining!

With this self-cultivation furnace, the efficiency of making Gundam can be at least doubled.

Lu Cheng nodded and said:

"It's not too late. Prepare tonight, and tomorrow we will leave for Yunnan."

Keke, Lu Cheng felt that he had been beaten in the face a bit.

After all, I just said I should stay at home.

Who knows, as soon as Lu Jin left, he had to go to the far door.

However, there will only be one or two weeks left and right, so nothing should happen.

Although he and Ma Ben are not strong enough, they have magical weapons to protect them.

Just be careful, even if you encounter a first-class stranger, you can get out of your body.

This is also the reason why the Ma family allowed Ma Ben to come out alone!

There are only a few hundred first-class foreigners in the entire foreigner world, and they are all people with a face and a face.

Except for the whole-sex group of lunatics, they rarely attack juniors.

Ma Benzai is also an active temper. Seeing that Lu Cheng is really going to find the Qinglong Mine, he is naturally willing to follow Lu Cheng as a horse boy.

After all, Qinglong Mine is the ultimate refiner material that refiners dream of!

He has only seen it a few times so far.

It would be great to find nature.

If you can't find it, you should just take a break, because he's almost bored here anyway.

night.

Lu Cheng drew a map according to his memory!

According to Ma Benzai's prompt, the approximate location where the Qinglong Mine might appear is marked.

When the time comes, just follow the route and look for them one by one.

After discussing the details, the two went to sleep separately!

The next day.

Lu Cheng took the carriage back to Lu Mansion early.

soon.

He saw Lu Shouyi playing Tai Chi slowly in the yard.

Lu Shouyi was also born as a foreigner. He is now over sixty, but he looks like he is in his early forties.

The average life span of a foreigner is several times that of an ordinary person!

Under normal circumstances, it is extremely possible to live a hundred years old, or even hundreds of years old!

Lu Shouyi saw that Lu Cheng came back so early, and said:

"Smelly boy, do nothing but go to the Three Treasures Palace, what the **** are you making when you come back so early today?!"

Lu Cheng smiled and said straight to the point:

"Hey, I want to use that car in the warehouse!"

Lu Shouyi frowned:

"This car has not been driven for several years, what do you use it for?"

"Besides, can you drive?"

Lu Cheng said directly:

"I'm a craftsman, can a car be hard to beat me?"

"I am going to drive to Yunnan to find some materials for refining."

Lu Shouyi raised his eyebrows:

"I think it's fake that you're looking for materials, but it's true that you're looking for the girl Xia Qiao."

"Listen to Dad's advice, this girl is not for you."

"You are the eldest son of our Lu family anyway. People look down on you, so you don't need to post it up."

"There are so many girls in this world, why do you have to hang on a tree?"

Ah? What's this all about!

Lu Cheng looked dazed.

Immediately, he reacted.

The fiancee who had retired from her marriage seemed to live in Lijiang, Yunnan.

This made Lu Shouyi misunderstood.

Lu Cheng said helplessly:

"Old man, I was really looking for refining materials, and I would have gone with me."

"I'm going to make a special magic weapon that needs the Qinglong Mine, which can only be found in Yunnan."

Seeing what Lu Cheng said was true, Lu Shouyi's expression eased:

"Isn't it going to find that girl?"

Lu Cheng spread his hands:

"What am I going to find her for? I'm a craftsman now. This identity is revealed. Most of the decent girls throw in arms, so I don't have the time to take care of her."

When Lu Shouyi heard this, he smiled happily and patted Lu Cheng on the shoulder:

"Okay, you're finally getting the hang of it, I'll get you the car keys!"

After a while.

Lu Shouyi got the car keys and accompany Lu Cheng to open the warehouse door.

Inside was a somewhat worn-out military vehicle with four seats.

However, the outside was covered with a thick layer of dust, which had obviously been useless for a long time.

Lu Cheng started the car and found that there was no way to start a fire!

Fortunately, before he entered this world, he read a book about car repair, but he quickly found the fault.

After half an hour.

The car finally started normally!

After Lu Cheng took some money from Lu Shouyi, he said goodbye to Lu Shouyi and returned to Ma Benzai's residence.

The two men cleaned up and saluted again, then left Lujiacun and headed to Yunnan!

Three days later.

Ma Ben was excitedly poking his head out of the car, looking at the rich land surrounded by mountains and rivers, and sighed.

"I have long heard that Yunnan is the land of mountains and rivers. All the Yaomeis here are very good at water. Now it seems that they are not fake." Ma Ben was smiling.

Now, although wars are breaking out all over the country.

However, the war hasn't spread here yet, so it looks surprisingly peaceful and peaceful here.

Lu Cheng curled his lips:

"Wipe your saliva, we are not here to find a wife."

Ma Ben was smiling:

"Brother Lu, I heard that your undocumented lady-in-law lives here, why don't we take the time to take a look?"

Lu Cheng opened the mouth and said:

"Look at a fart, just what a melon lady has to see."

"Hurry up and find the Qinglong Mine is a serious matter!"

Lu Cheng followed the trail ~lightnovelpub.net~ to the designated direction.

Now that the sky is getting dark, I have to hurry to the next market town to take a break.

Tomorrow, I have to go to the first location where there is a suspected Qinglong mine!

However--

When Lu Cheng drove halfway, the car made a loud roar.

It seems that the tire has burst!

Lu Cheng braked, causing the car to stop urgently.

The car just stopped.

In the bushes ahead, there were three strong men, holding their guns, and walking out slowly.

Seeing this, Ma Ben couldn't help complaining:

"I just said that it was from the land of mountains and rivers. I didn't expect to surprise us as soon as I arrived."
