The next morning, Ye Fan set off to the black market at the base to purchase the evolution crystals and food needed for advancement. Due to the relatively large amount of purchases this time, he was afraid of any trouble, so he invited Qin Yufei to accompany him, although Qin Yufei has always been lukewarm to him, but after all, he still owes him a life-saving kindness, so of course he will not refuse this little thing.

As soon as Qin Yufei heard about what he was going to buy, he naturally guessed that he was going to complete the advancement, and he was a little surprised, and then he was a little sour and unwilling. She has always been so strong, even her own brother Qin Yulin advanced to the second order in a month, she was jealous more than excited, not to mention Ye Fan, but fortunately, she was still literate, so she didn't say anything sour.

With the help of this eldest lady of the Qin family, everything went smoothly, even the evolutionary yuan crystal, which was relatively difficult to buy, was also recommended by Qin Yufei, and it didn't take long to get it, but the price was a bit black, and it cost Ye Fan five hundred and twenty taels of gold, which was equivalent to five million yuan before the end of the world, which was half the normal price, but this is also normal, this is originally a black market

As for the five tons of food, it cost Ye Fan 470 taels of gold, don't think that this price is very expensive, you must know that the food trade is controlled now, and the base military has a very serious control over the food trade in order to prevent the merchants from hoarding, and only in this black market can you buy such a large amount of food at one time, and the food that Ye Fan wants needs to be rich in protein, so cheap food like instant noodles and rice is not good at all, he mainly buys canned meat and fresh fish from Poyang Lake, so it is currently very rare food, The price is so expensive!

Advancement is really a money-burning thing!

Fortunately, there is a generous bounty in exchange for Ma Dongqiang's head, otherwise it is really not easy for Ye Fan to get so much gold, it is estimated that he will have to sell a few black metal weapons, but the black metal weapons are too eye-catching, and he may cause trouble if he takes them out rashly, he is still relatively weak now, and it is impossible for the Qin family brothers and sisters to protect him all the time, so he definitely does not want to take this risk as a last resort.

After all the things were purchased, Qin Yufei entrusted the relationship again and found a truck to help Ye Fan transport it back to Hot Spring Town, which cost Ye Fan another ten taels of gold.

The material value in the last days is simply outrageous!

In the process of returning home, an accident occurred, that is, on the way, he encountered a convoy of more than 30 trucks, Qin Yufei saw the other party's flag, and immediately asked the driver to stop on the side of the road to avoid.

"Whose convoy is this, so majestic, even you are so afraid" Ye Fan couldn't help but ask Qin Yufei curiously.

Qin Yufei glanced at him and said, "I'm not afraid, but respectful, this is the [Stone King]'s convoy." ”

"[Stone King]?! Could it be one of the four third-order powerhouses on the same level as [Magnetose]?! Ye Fan was quite surprised.

"Well, if I'm not mistaken, these thirty or so trucks should be filled with the corpse of the third-order alien beast he hunted a few days ago."

"You mean, so many trucks are loaded with the corpse of a strange beast?!" Ye Fan exclaimed.

You must know that each of these more than 30 trucks has a load capacity of more than 12 tons, and the total cargo capacity of this fleet is estimated to be 500 tons! In other words, the corpse of this third-order alien beast is at least five hundred tons!

What is the concept of 500 tons, it is simply a small mountain! You must know that the elephant, the largest land creature on earth, weighs only ten tons!

Qin Yufei glanced at him with disdain and said, "You are rare and strange, there are many third-order beasts that weigh more than five hundred tons, which is not surprising, and the fourth-order beast Kumbra that [Magnetogod] killed last time is said to weigh more than three thousand tons, if you want to use the truck to pull it back once, it is estimated that it will cost two hundred!" Don't you be scared to death when you see it?! However, the corpse of this monster is too big, and in the central area of Poyang Lake, after being killed, it sank to the bottom of the lake, and there is no way to salvage it. ”

In fact, she was pretending to be cold and noble, deliberately hitting Ye Fan, in fact, when she saw the corpse of a third-order beast for the first time, her shocked expression was even more exaggerated than Ye Fan

"What are they pulling these bodies back for? Refining dark metals? But it can't be done like this, first-order alien beasts can also refine dark metal, and their corpses are much luckier. Ye Fan asked.

"Because the corpse of a first-order alien beast can only refine the lowest-level dark metal, such as bronze, while the corpse of a high-level alien beast can refine a higher-grade dark metal! Do you know the Magneto's weapons? It was a black dragon lance with a head made of a black metal called manganese, which was said to be 50 times harder than steel and 20 times harder than diamond and copper! It is absolutely indestructible to all things on earth, and even the hardest diamond is as fragile as dirt in front of it! And its ability blessing effect has reached more than 160%! Far more than bronze! ”

Qin Yufei's eyes showed an obvious look of yearning, and he continued, "This dark metal is extracted from the body of a third-order alien beast!" It is said that a piece of metal the size of a spear head was extracted from a total of more than 2,000 tons of corpses, but do you dare to say that it is not worth it?! ”

Ye Fan suddenly realized, and while he was envious, he also thought a little carefully: since his right hand can more efficiently refine the dark copper from the corpse of the first-order alien beast, I don't know if it can also refine this higher grade dark metal more efficiently, if it is really possible, then if he cooperates with the stone king, help him refine more than ten times more high-grade dark metal, and then let him share a little bit of himself

"No! It's too dangerous! Soon he dispelled this idea, this is simply a tiger skin, with the strength gap between him and the stone king, there is no qualification to cooperate with him at all, if the stone king knows his ability, it is very likely that he will be imprisoned and become his own refining machine! Ye Fan didn't have the power to resist at all!

Ye Fan resisted the temptation of high-grade dark metal, and gave up this idea, it is important to improve his strength first, only after his strength is improved, can he be qualified to talk to the strong!

For now, it's better to refine the dark copper, if you have the chance, you can find the corpses of some second-order alien beasts and see if you can refine some interesting dark metal

Wrong! There is a better option! That was the fourth-order alien beast Kumbra that was hunted by the Magneto! It's right at the bottom of Poyang Lake right now! Although it has been placed for more than three months, the corpse of the alien beast has always corroded relatively slowly, and there should still be a lot of remnants, even if it really all rots, the bones should still be there! 3,000 tons of corpses, how to say that there are hundreds of tons of bones! With his refining efficiency, he should be able to refine a lot of dark metals!

It's true that it can't be salvaged! But his refining method is different, and there is no need to salvage and transport the corpse at all! Just dive to the bottom of the lake and you're good to go!

Thinking of this, Ye Fan suddenly became excited: The Xuan Meng that the Magnetic God refined from the body of the third-order alien beast is so awesome, and the Xuan Metal refined from the fourth-order alien beast should be so awesome!

However, this matter is not so simple, although the strongest alien beast in Poyang Lake, Kumbra, has been killed, but there are still countless alien beasts rampant, even the fleet of the base needs to hire many evolutionaries to escort before daring to sail!

Therefore, with his current strength, it is very dangerous to go deep into the bottom of the lake, and he must think long-term.

It's better to wait until the advancement is completed before going, anyway, it's not bad for a few days, and then spend money to hire some stronger evolutionaries to escort you, of course, you have to make up a good excuse, you can't let them know the truth

Well, that's it!
