The three-dimensional picture that was passed over was like an underground building somewhere, and the four walls were all made of metal, but what surprised Chu Feng the most was the two big words "Vault" written on it.

"Mia, this place is a place for gold reserves?" Although Chu Feng was not short of money, he was still a little excited when he saw gold.

"Master, according to Mia's analysis, it is indeed a place to reserve gold. Mia replied.

"Can I enter the system inside?" Chu Feng asked again.

"Master, the powertrain inside is destroyed, and Mia can't break in, but she can connect with the robot spearhead. Mia said.

"Can you locate the coordinates, where is it?"

"The coordinates have been confirmed, now open the hologram for the owner. ”

Chu Feng originally wanted to see if there was really gold stored in it through the "Machine Spearhead", but due to the defense there, the Robot Spearhead couldn't force open the warehouse door at all.

"It seems worth a visit in person. Chu Feng smiled lightly.

Relying on the docking array-type teleportation ability, Chu Feng quickly came to the front of the "machine spearhead".

"Mia!" Chu Feng called softly.

"What does the master command?" Mia's sweet voice rang out.

I don't know if it was the data that prompted her to evolve, but now Mia, whether in terms of voice or response, is not like a program, but like a spirit that retains her sanity.

"Mia, can you still control the 'flying machine' now?" Chu Feng asked with some curiosity.

"Yes, what does the master need Mia to do?"

"Mia, what is the limit of your long-distance control?" Chu Feng asked again.

"The data is insufficient, but the master needs Mia to do some experiments?" Mia asked.

"No, I'm just curious to ask. Chu Feng's gaze swept around, and even exerted his divine sense.

He found that the metal used here was extraordinary, and it was no wonder that even the top robots could conquer it.

"The metal around here seems to be a good raw material. Chu Feng muttered.

"Master, this is 'dense titanium steel', which can be processed into many important parts, but the processing requires a high-pressure melting furnace. Mia introduced.

"Even if there's nothing in there, this trip isn't in vain. Chu Feng nodded lightly.

He didn't know what the "high-pressure melting furnace" Mia was talking about, but he could try to use the "Heavenly Energy Fire" to refine it, and since he obtained the "Heavenly Energy Fire", he had never used it well.

Walking to the gate that looked like an entrance, looking at the protruding circular metal gate, Chu Feng gently placed his palm on the cold handle.

Under the effect of "Divine Sense", Chu Feng already understood the internal structure of the metal door, and even Mia obtained the corresponding information at the first time.

"Master, Mia can open this door!" Mia said suddenly.

"Okay, you can open it!" Chu Feng also happened to want to know more about Mia.

With the sound of several metal gears turning, the air holes around the gate began to press outward, and it didn't take long for the guards of the steering wheel to turn themselves.

"Mia, well done. ”

The metal door is opened, and inside are passages with traps, some of which are ineffective due to power outages, while others are triggered.

Of course, no matter what kind of organ it was, it was impossible to harm Chu Feng.

All the way to the innermost warehouse.

After seeing the gold bricks inside, Chu Feng was stunned for a while, he never expected that the gold reserves would be so exaggerated.

Using the gold bricks here, it is not a problem to build a large hall.

Chu Feng had also obtained a lot of gold before, but compared to here, it was like the difference between an ant and an elephant.

You're welcome, Chu Feng did a porter and collected all the gold here.

Now his space is more than enough, and with the improvement of his realm, his perception is several times stronger, and he will definitely not miss a piece of gold.

Gold is a good thing, and it acts as a currency in many parts of the world.

Chu Feng's journey through time has just begun, and when he reaches the next world, gold will be able to play a big role.

"Master, gold has now been reduced to a type of metal, and if the master is interested in gold, Mia will pay special attention to collecting it. Mia seemed to see Chu Feng's need for gold.

"Hmm!" Chu Feng nodded, with a smile on his face.

In this trip to the end of the world, he has really gained a lot, and it is estimated that he has already blossomed in his heart.

Next, it is time to start the collection of "dense titanium steel", although it is a little troublesome, but it is just a chance to give Chu Feng a chance to move his hands and feet.

Under the action of "natural energy fire", even the "dense titanium steel" with a high melting point is easily turned into molten steel.

Through his divine sense, Chu Feng was able to clearly know the subtle impurities inside the "molten steel", and he tried to purify it, and then condensed the "molten iron" into various shapes.

"It seems that I have a lot of potential as a 'refiner', but unfortunately I don't have a teacher's guidance, so I don't know how to engrave the formation into it. ”

Chu Feng whispered as he tried.

Now, he can make all kinds of parts accurately based on the structural drawings provided by Mia.

Naturally, it was also possible to make weapons directly, but when trying to integrate the formation into it, all failed.

Without the integration of the formation, no matter how precise the things he refined, they were just ordinary products.

"With this ability of the owner, it is much easier to build a production base. Mia said in a happy tone.

Chu Feng also smiled.

Although the parts he refined were good, the efficiency was too low, and it was okay to make some scarce parts, if it was to refine in large quantities, I am afraid he would not have that time!

After some attempts, he finally collected all the "dense titanium steel" here, and Chu Feng found that the true yuan power he consumed was very small.

It seems that the improvement of the realm has allowed him to transform and absorb the true yuan power, and I don't know how many times it has increased compared to before.

Returning to the aircraft, Lambena and the others were still following Mia's auxiliary guidance and learning about the control of the aircraft.

Chu Feng didn't bother them, found a room, and began to practice alone.

Two days had passed in a flash, and Chu Feng had been in retreat for two days, and when he came out of that room, Lan Bena and the others had been able to skillfully control the various equipment inside the aircraft.

Through Mia, Chu Feng learned that the search for resources in the vicinity was almost underway, and it was time to leave here.

"Master, where are we going next?" asked Mia.

Without Chu Feng to speak, even if Lan Beina and the others knew how to control this flying machine, they would not be able to drive away.

Chu Feng reported a coordinate, and then said, "Just go there!"

The coordinates he was talking about were exactly the places Witt had mentioned.
