From Lockheed, he knew the purpose of those meteorites, which were used to study a new type of high-tech metallic material.

Once this metal material is developed, it will be used in aircraft engines and the military industry, making many cutting-edge technologies that originally existed only in the imagination a reality.

The advanced weapons produced will be two generations ahead of similar weapons of other countries by leaps and bounds.

This generational gap is too huge.

You must know that take the US imperialists' Raptor F22 fighter as an example, when it first came out, the F22, as a fourth-generation aircraft, completely crushed and beat various models of third-generation aircraft around the world, and the latter had no backhand power at all.

It is conceivable how terrifying the two generations ahead will be, and I believe that all the air forces in the world combined will not be able to defeat US imperialism, and its hegemony will not be shaken.

This is the strength brought by that kind of metal material, so it is not difficult to imagine how huge the value of those few meteorites is, and I believe that even if you pay more money, the US imperialist will not sell it.

Of course, now that those meteorites have been taken by Ye Feng, they will naturally enter his pocket.

"Haha, it's really heaven helping me, I'm worried that I can't find the material to upgrade the flying sword, but I actually found a good material here, and it's still as many as seven or eight pieces."

Ye Feng's face flashed with joy, so he no longer hesitated, and directly went out with a wind blade, splitting Lockheed into two and killing him, his body was as fast as a ghost, and he came to the basement where the meteorite was stored in a few ups and downs.

Although there were several half-meter-thick alloy security doors along the way, under Ye Feng's powerful sword qi cutting, they were completely like tofu, and they were cut in three or two clicks.

The killing and liquidation outside is still continuing, Ye Feng will not participate, and will be handed over to Long Dahai and Utas.

The basement is about 1,000 square meters and has three large rooms, one of which is where the meteorites are stored.

There are a total of eight pieces, seven of which are dark brown, this color is already a good product in the dark iron, it can create a very powerful magic weapon, and it can be sold for at least a few thousand medium-grade spirit stones in the large treasure pavilion of the cultivation realm.

As for the other piece, it was placed alone in the corner, black as ink, invisibly flashing luster, Ye Feng could see that this meteorite had traces of being cut, but it was not cut successfully, leaving only shallow white marks.

"It's... This is the World Stone! ”

Ye Feng's hand trembled slightly, and his face showed an extremely excited look, he didn't expect to find a world stone here, and it was a world stone that was enough to laugh at the size of an adult.

The World Stone, he had seen it in the sapphire that Yun Qi was wearing, but there was only a little bit of it that didn't even have sesame seeds, and even if he got it, it wouldn't be of much use.

Later, he also inquired about this, and went to the jewelry store where Yunqi bought the sapphire to inquire, but to his disappointment, the sapphire was caught by a Burmese fisherman from the sea and later sold to a jeweler, and he did not know the origin of the sapphire.

He thought that it would be impossible to find the World Stone again, but he didn't want to find a large piece in the Locke family.

The World Stone, its material can be called the toughest existence in the universe, even the most powerful True Immortal Emperor cannot destroy it, only change its shape, this is the best material for refining and improving magic weapons.

"If I use the World Stone to refine the flying sword again, the power of my flying sword will inevitably increase exponentially, with the sword intent of Shura, who else in this world can stop its edge, I am afraid that who will be the killing god!"

Thinking of this in his heart, Ye Feng could no longer suppress the excitement in his heart, and immediately sat down cross-legged, opening his mouth to spit out the true fire of the Purple Mansion.

As soon as the true fire appeared, it immediately made the entire space become scorching, and the surrounding world stone was controlled by Ye Feng, and it began to smelt slowly, making a "crackling" sound.

As the hardest material in the universe, the toughness of the World Stone can be imagined, and it is extremely difficult to refine, but it is not impossible to refine, but the process is extremely slow.

But Ye Feng was not in a hurry, if he could make the flying sword more powerful, even if it took more time, what was it.

Time flies.

Ye Feng urged the True Fire to refine the World Stone, and it took three full days before it could be refined from an adult-sized World Stone to the size of a palm, which had completely turned into a viscous liquid like black sesame paste.

This amount is already the limit that Ye Feng's flying sword can withstand, and no matter how much flying sword there is, it will not be able to withstand exploding.

The flying sword is like a truck, it also has a load, which is determined by the strength of its sword tire, and the strength of the sword tire is directly related to the cultivation of the owner of the flying sword.

Therefore, in the final analysis, Ye Feng, who had only cultivated the sixth layer of qi, could only withstand such a large number of world stones with the flying sword he forged.

"There's no way, that's how low cultivation is, many things will be restricted, so you can only continue to condense after your cultivation is high."

Ye Feng sighed helplessly.

"Whoosh!"

Without the slightest hesitation, he immediately smashed this bit of black paste into the flying sword "Black Rock" that had already been burned red by him with real fire.

Zizizizi!

There was a sound of the soldering iron entering the water, and I saw that the originally rough flying sword had become smooth and round, invisibly exuding a sharp aura, forcing people to dare not look directly, and also emitted a "buzzing" sword groan, and the sword body trembled, as if a divine sword was about to be born.

"Whoa!"

After the condensation was completed, the flying sword directly rose into the sky, splitting the foundation with a thickness of ten meters above the head, cracking a huge opening, which instantly caused a violent collapse.

"Good baby, at least you have reached the middle grade spirit weapon."

Ye Feng retracted the flying sword, looked at it, couldn't put it down, looked at the foundation that was about to collapse, and hurriedly put all the eight meteorites into the storage ring.

At the same time, he also hurried to another room similar to a laboratory, and collected some of the drawings of aircraft and warships that seemed to be very secret, otherwise it would be a waste to bury them inside.

How did he know that those drawings were the top military designs of the US imperialists, which belonged to the top secret of top secrets, and they were things that countless scientists had spent decades researching, but they were taken away by him at once.

If the top brass of US imperialism knew about this, I am afraid that they would be desperate to play with him.

"Boom!"

Bauhinia Manor, Long Dahai and Utas were waiting on it, when they suddenly felt a vibration on the ground, and then an extremely luxurious villa in front of them, almost half stepped down.

Long Dahai's face changed, and he thought that something had happened to Ye Feng.

Ye Feng had sent a message to him before, and it seemed that he was doing something in the basement under the villa, so he had been waiting above.

Just as he was about to rush in to find out, Ye Feng's figure had already rushed out of the collapsed ruins.

"Sect Master Ye!"

Seeing that Ye Feng finally appeared, Long Dahai was also secretly relieved and hurriedly ran over.

"Well, let's go."

Nodding, Ye Feng smiled at Long Dahai.

He was very satisfied with Long Dahai's performance, even if Ning Susu brought back the news of his father's death in the plane crash, he still did not change his original intention, and he was grateful for his father's kindness to him.

Such a loyal person, he will not be treated badly in the future, and will make the other party go to a higher level and reach a higher height.

Soon after, Ye Feng, Long Dahai, and Utas returned to Ning's house.

"What, Xiao Feng, are you going back to Huaxia?"

After hearing Ye Feng's decision to leave, Ning Zetian stood up, his eyes were full of reluctance, in his heart, Ye Feng was already his appointed family heir.

Ye Feng nodded, he came to the United States to find clues about his father, and now he has found it, and he also learned that his parents entered the small world of heaven and man from the Tibetan glacier, because he was worried about the safety of his parents, the only thing he wanted to do now was to go to the Tibetan glacier and find the entrance to that small world.

"Actually, I suggest that the Ning family is better to turn back to China for development, it is not safe to stay here after all, although I helped the Ning family destroy the Locke family, but it seems that the Locke family is involved in the American Imperial Society, I am worried that after I leave, others will target you."

After a pause, Ye Feng opened his mouth to propose.

He took away those few meteorites, as well as some top-secret cutting-edge scientific and technological drawings, if he was a US imperialist, I believe he would definitely go crazy.

"Good! Then turn back to China, go to Jinghai City, haha, as the saying goes, fallen leaves return to the roots, this is not my hometown after all, then listen to you, our Ning family will resell the industry here, and then return to China for development! ”

Ning Zetian almost only thought about it for a moment, and then agreed, one is to consider that the dangerous factors that Ye Feng said will bring a fatal blow to the entire family, and in one, he doesn't want the Ning family to have no successor, since Ye Feng wants to return to China, then return to China.
