The group killed all the mutant beasts they encountered on the way back, because what they lacked now was the skeleton.

During this time, I met a third-level mutated bird of unknown species again.

The bird is extremely fast and very aggressive.

If it weren't for Ye Yan's promotion to the third level, it would really be difficult for everyone to deal with this third-level mutant beast that could fly.

When I returned to the research center, it was almost completely dark, although it was still evening.

After Wen Yuannan recovered a little mental strength, he immediately healed everyone again.

Ye Yan originally planned to let everyone rest, and he disposed of the corpses of the countless mutant beasts in the space bracelet.

But no one was willing to rest and cultivate their spiritual power by themselves, and they all started to help.

When Ye Yan took out all the corpses in the space bracelet, everyone felt that their eyes were dark.

That's too much, isn't it?

Only then did everyone realize how many mutant beasts they had killed in the past two days.

Among them, the most conspicuous is the corpse of a third-level mutant bear, and the corpse of a third-level mutant bird.

The others are all second-level mutant lifeforms.

Although they are second-level mutant lifeforms, the beast bones should not have color, but there are still a lot of useful materials on them.

Ye Yan began to process the corpses of the two third-level mutant beasts, while the others quickly disposed of the other corpses.

When Ye Yan couldn't wait to cut the meat and look at the bones inside, he was a little excited!

The beast bones of the third-level mutant bear are silver!

Ye Yan immediately dissected another third-level mutant bird.

Sure enough, it's silver too!

Both of these beast bones can be used!

And in Ye Yan's space bracelet, there is also a silver beast bone of a third-level mutant snake!

And there is a hint of gold in the silver! It's even more precious when you look at it!

Everyone also saw the silver bones, and they were immediately overjoyed, knowing that there were two more beast bones that could be used!

But Ye Yan can't make combat uniforms yet, because Yijin hasn't been made yet!

Ye Yan handed over the task of sorting out the corpse to everyone, and immediately found a quiet place and started making foreign gold!

In the space bracelet, there is also a large amount of blood from yesterday's two wolf-type alien beasts, and Ye Yan doesn't know how much alien gold can be made.

Iron is easy to find, although the town has been ravaged by zombies, but all kinds of things are still available, and iron is even more difficult to find.

Ye Yan found a lot of iron, and then used refining techniques to refine them into molten iron.

The first-level magic crystals on Ye Yan's body are already as many as a thousand, which is completely sufficient.

And now that everyone has become a two-star evolutionary, if no new members are added to the core team in the future, there will be no need for a one-star evolutionary agent in a short period of time.

After a few days of hunting, there are hundreds of second-level magic crystals, but Ye Yan thinks that second-level magic crystals are still very useful, maybe they can exchange good things from traders, and when they make foreign gold, they can't use up the two-star magic crystals.

So, in this large pile of molten iron, Ye Yan directly poured half of the blood of the alien beast he had, and then put in five hundred first-level magic crystals.

After the materials were mixed, nothing changed.

The magic crystal is the magic crystal, and the whole piece sinks inside.

The molten iron and the blood of the alien beast showed no signs of fuse.

Ye Yan immediately activated his spiritual power.

Suddenly, the mixture, which had not reacted at all, immediately changed!

Ye Yan's powerful and pure spiritual power that had been honed by the spiritual cultivation technique acted on it, and the magic crystal immediately showed signs of melting!

Ye Yan felt that as the magic crystal melted, a wave of energy gradually overflowed.

Blood and molten iron, after the energy of the magic crystal overflowed, also changed, and began to mix gradually.

During this period, Ye Yan could feel the change and combination between the three substances, and after the recombination, this substance appeared with powerful energy.

And Ye Yan, who was in charge of all this, understood very well that it was not only his powerful spiritual power at work, but also the effect of the golden scroll of the Doomsday Battle Armor.

After Ye Yan learned the golden scroll, the scroll seemed to disappear, but it was actually integrated into Ye Yan's body, as if giving Ye Yan a privilege to be able to make foreign gold and be able to make a series of doomsday armors.

So Ye Yan is now very sure that if other people know the simple materials for making alien gold, and they are a professional with spiritual power, it is impossible to make alien gold and other doomsday armor series!

Because they don't have drawings and don't get privileges!

Ye Yan looked excitedly at the changes between the three.

He didn't skimp on his mental power, and all of it was concentrated in the liquid under his hands!

Finally, after the fusion of the three substances, it completely turned into a deep black!

But Ye Yan knew that this was not over.

His mental power did not decrease in the slightest.

Sure enough, with a mysterious black liquid with great power, it gradually began to solidify.

This process is very long, even longer than the complete fusion of the three substances.

Because it's the equivalent of grinding, you want to make the solidified solid harder!

Although Ye Yan was making foreign gold for the first time, he was very handy when he learned the golden scroll.

One of the reasons for this is his huge and pure spiritual power.

If the foundation of the spiritual power is not solid enough, you can't hold on to it during the period, and the mental power is broken, then everything will be wasted!

Fortunately, Ye Yan got this thing, otherwise someone else got it, I'm afraid it would have been idle for a long time!

Because even Ye Yan felt that he had consumed too much spiritual power.

And Ye Yan's cultivation of spiritual power not only has the help of purple magata, but also the help of gold-level spiritual cultivation techniques!

The sum and purity of his spiritual power are no longer comparable to ordinary people!

The foreign gold has already been formed, but Ye Yan is still outputting his spiritual power to polish.

Heterogold is a deep black color that emits a strange glow.

Although black is the color that exists in this world, when you look at the unusual and treacherous aura of foreign gold, you won't think that it is a metal that exists in this world!

Finally, Ye Yan thinks it's time!

He stopped the output of mental power!

Ye Yan carefully looked at the foreign gold in the huge container.

With so many materials, the amount of foreign gold produced has already shrunk a lot, but the quantity is still very large.

In the process of production, when the foreign gold was still in a liquid state, Ye Yan deliberately used his spiritual power to evenly separate the liquid.

Now, the finished gold is the size of a fist, and it is square.

Such a fist-sized alien gold, using a large amount of molten iron, the blood of a huge alien beast, and five hundred first-class magic crystals, the fist-sized alien gold made is almost the number of magic crystals, five hundred!

Ye Yan excitedly picked up a piece of foreign gold.

Although in the process of production, as the leader, Ye Yan has been mentally prepared.

But when he really picked up the molded foreign gold, he couldn't help but be shocked!

This is worthy of a metal that does not exist in this world, whether it is hardness or whatever, it is not comparable to the metal in this world!

And the gold itself seems to have a huge deterrent power!

Ye Yan can imagine how perverted the weapon would be if the alien gold was used to make weapons!

Ye Yan picked up a piece of foreign gold and walked outside.

At this time, it was completely dark, but Ye Yan didn't know what time it was, he was completely immersed in making foreign gold just now, and he didn't know how much time had passed.

Although the sky is completely dark, as two-star evolutionaries, everyone's eyesight is not ordinarily good.

In their eyes, there is little difference between night and day.

Seeing Ye Yan come out with a piece of metal in his hand that they had never seen before, everyone was immediately attracted to attention!

This is the gold!

Ye Yan was surprised to find that the work of disposing of the corpse of the mutant beast was almost completed, could it be that it took so long to make the alien gold by himself?

Everyone immediately surrounded Ye Yantuan!

Among them, Qi Fan, who was the most curious and excited, immediately said: "Boss! It worked? Is this alien gold? ”

Ye Yan replied with a smile: "Yes, this is Yijin." ”

Before Ye Yan finished speaking, Qi Fan said, "Boss! Can I take a look at it! ”

Ye Yan shook his head helplessly and gave the foreign gold to Qi Fan.

Qi Fan, who was full of curiosity about everything, immediately picked up the foreign gold, touched it, smelled it: "Boss, this is the foreign gold made of the blood, magic crystal, and iron of the foreign beast?" It's awesome!! I don't believe there's anything else on Earth that's stronger than this! ”

As a science fan, Qi Fan naturally knows no one better than him.

Qi Fan continued: "But it's amazing! It's just ordinary iron, but it can be mixed with the blood of magic crystals and alien beasts to make such a hard and magical metal! It's simply magical! I know! This incident also shows that the magic crystal has a huge amount of energy, otherwise it would be impossible to make such a terrifying thing that does not exist on the earth! ”

Everyone looked at Qi Fan, who was muttering excitedly, and they all smiled dotingly.

Ye Yan succeeded in making a different gold, and everyone was happy.

This is Ye Yan's first attempt, and he has successfully made such a high-quality foreign gold!

I think that at the beginning, when Ye Yan got the black cut drawing, he tried several times before making the black cut.

I made a more powerful black cut, and I tried it countless times!

And now, this alien gold is not an existence in this world, and the difficulty of making it is obviously more than one level higher than that of Black Cut, and you can know the gap by looking at the color of Black Cut's drawings and the color of the Doomsday Warframe drawings.

But Ye Yan can make it all at once!

This only shows one point, that is, Ye Yan has become much stronger!

And it's a mental strength!

Yes, if you use the gold-level spiritual cultivation technique to cultivate spiritual power, it is strange that your spiritual power is not greatly improved!

All the people in the team were cultivating using the Spiritual Cultivation Technique, so they naturally knew the power of the Spiritual Cultivation Technique.

But only Ye Yan knew how much mental power it cost him to make these foreign gold!

He originally thought that his spiritual power was already invincible because of his spiritual cultivation technique!

Now, when he encounters the Doomsday Armor, his mental power is still not enough!

At this time, his spiritual power is about to be on the verge of deficit!

Originally, I wanted to make a combat uniform tonight, but I had to wait for tomorrow.

Ye Yan told everyone about the situation, they had to go to rest first to recover their mental strength, and told everyone to rest as soon as possible, and they would leave here tomorrow and set off for Broken Valley.

Everyone agreed, but no one knew that someone had already preempted them.
