"Smack!"

As the treasure map key was tightly embedded in the groove of the box lid, the machine inside the treasure box finally made a sound of unlocking, and the box lid popped open a small gap.

Feren glanced into the chest, and to his disappointment, it was almost empty, with only a gray ring lying at the bottom of the chest, and a piece of origami like gold leaf on the side.

"Huh?!"

Seeing this scene, Fei Lun immediately frowned, because he had also heard some about others opening treasure chests, but it didn't seem to be the same as his own this time, so after realizing this, he instantly exuded his divine sense and wrapped himself in the treasure chest, and was stunned to find that an unknown substance was emitting from the open treasure chest, and this substance had been spreading for a while, and the first one to spread was a hundred meters away.

Although Fei Lun was 100% sure that this unknown substance did not cause damage to the human body, he still had a feeling of panic, which was a warning sign, but he didn't know where this warning sign came from, not to mention that at this time, his divine sense was shrouded, and nothing within a radius of a kilometer could escape his eyes, but he couldn't find any danger.

"No matter ......"

Fei Lun tried his best to shake away the warning signs in his heart, picked up the gold leaf paper in the treasure chest and opened it to take a look, only to see that the universal text of the reincarnation space was written on it, and he just happened to recognize: "Dark gold-level item, an unknown dual-system fusion ring, it needs to be refined!" ”

Seeing this, Fei Lun raised his eyebrows, somewhat gratifying. Because the treasure opened in this treasure chest is at least worthy of the outer packaging box of the dark gold level, how to say that it is also a dark gold ring, although I don't know what attributes it is. But it's better than opening a gold-level item, right?

Besides, Faren knew that things that could only be used without direct blood dripping but requiring mental sacrifice were good things, so he did not hesitate to sit down cross-legged on the spot, put his palms together, and wrapped the dark gold ring in the palm of his hand. Begin the sacrifice with divine consciousness.

After about three hours, Faeron finally reached the final step of refining the dark gold ring, which was said on the platinum paper. "Need to sacrifice the mind and spirit", in the paragraph just now, Fei Lun's "God (Consciousness)" is there, but he still lacks the heart. So to this final step. He jerked out a drop of his heart and landed on the dark gold ring, and this was the final step.

After spending a drop of hard work, Fei Lun looked a little tired, but in the next thought, he sensed the overall attributes of the ring: "It can fuse a ring of dark gold and below to retain its attributes; The first stage of the wind system, the first order of the wind blade, semisonic; X-series. Unknown, not yet open; All of the above can be upgraded! ”

After Feron learned the attributes. The expression on his face was extremely weird, because the upgradeable dark gold ring was definitely a treasure, but unfortunately several attributes of this ring were really bad, one was to fuse the other ring, this one was basically useless to Faerun, after all, he had no other ring equipment on hand except for the "hidden ring", and the function of the hidden ring was really insignificant, except for hiding himself, there was only storage left. As for things like the wind blade, it's okay to deal with ordinary people, but it's basically for nothing to deal with strongmen above the late second-order level, after all, the "semisonic" speed is too slow.

"Huh? Storage? Can I upgrade? Faeron then thought of the question, if he could, would his storage space be larger? Just when he wanted to give it a try, the piece of gold leaf paper thrown on the ground suddenly lit up with a yellow light, and then the font on it suddenly changed.

"Now that the treasure collector has finished refining the ring, he should know that there is another rare thing to collect in the treasure chest, which is called: low-grade biocatalyst!"

Just as Fei Lun was staring at the lines of reincarnation space words, the piece of gold leaf paper on the ground spontaneously combusted without fire and dissipated into the air.

"Holy!" Fei Lun couldn't help but burst into a foul mouth.

It's no wonder that before the sacrifice ring, he had a warning in his heart, and the daring was sent against this harmless microbial catalyst. This kind of catalyst can not change or help high-level organisms to carry out genetic optimization, but can have a catalytic effect on low-level organisms, such as single-celled organisms or viruses, etc., and its specific effect depends on the species, but it is definitely effective, in other words, single-celled algae, E. coli in the human body, and even cancer cells, may enhance a certain ability, this is not the worst, the worst is that the Chosen Virus will also be affected by it, and it is difficult to predict what kind of consequences will occur......

The most fucked up thing is that because there was no one around, Fei Lun didn't care about the open treasure chest after he started to refine the dark gold ring, and now a few hours have passed, and the substance (catalyst) that was discovered by Fei Lun's divine sense has long since spread out of Kuda Island with the wind, floating everywhere, and he can't do anything if he wants to intercept those catalysts.

"What's the matter with love!" Fei Lun sighed helplessly, and simply stopped paying attention to this, anyway, the catalyst itself is harmless, no matter how much he tosses, it is impossible to exterminate the human race! As for the sudden increase in mortality, that is a problem that the political axe bosses of various countries should consider, and he will send an email to the political axes of various countries when he returns to HK at most to remind him!

After figuring it out, Faeron pulled out the contents of the Hidden Ring in one go, laid them all on the clearing, and began to merge the two rings...... About half an hour later, the two rings were combined, and Fei Lun glanced at the attributes again, and was immediately happy: "The wind system hidden ring, the storage space is one cubic meter, and the energy can be upgraded; The first stage of the wind system, the first order of the wind blade, semisonic speed, can be upgraded with energy; X-series, unknown (not yet open)! ”

Although there is a "can be upgraded with energy" in the new Wind Hidden Ring, if ordinary people get this thing, they really don't know how to use energy to upgrade the ring, but it does not include Fei Lun, because in the reincarnation space before, he has encountered eight pieces of similar equipment if not ten, and he is already familiar with it.

In fact, the process of upgrading the equipment of this "usable energy upgrade" is quite simple, as long as the equipment is exposed to the purebred form of energy, it can absorb itself, and then upgrade, as for the storage equipment, it is more convenient, whenever it ingests pure energy, it will automatically absorb one-tenth for the purpose of upgrading.

Sure enough, when Faeron re-ingested the pile of miscellaneous things on the ground into the Wind System Hidden Ring, he felt that the more than 160 life sources he had accumulated were instantly reduced by one-tenth.

Originally, Fei Lun still had more than ten life sources in the old cellar, and later in the huge corpse pit of more than 3,000 people in the Cape Town military camp, he used the blood Asura Pendant to select the best of the best (if it is completely rotten, it is useless) to absorb and condense nearly one hundred and fifty life sources, and then he had a family background of more than one hundred and sixty pieces, but as soon as he put it into the wind system hidden ring, it suddenly lost more than sixteen pieces.

However, the result was quite gratifying, and Fei Lun's divine sense instantly received several upgrade messages: "Absorb two life sources, and the Wind Hidden Ring will be upgraded to the second order, and the progress will be two-tenths; The ring concealment function cannot be upgraded; The storage space has been upgraded to two cubic meters; The wind system is upgraded to the second stage, the second order wind blade, subsonic speed (0.75 times the speed of sound), and the X system is not turned on......"

"Absorbing the four life sources, the Wind System Hidden Ring has been upgraded to the third order, and the progress is three-tenths; The ring concealment function cannot be upgraded; The storage space has been upgraded to four cubic meters; The wind system is upgraded to the third level, the third-order wind blade, the speed of sound, and the sonic boom effect; The X series is not turned on......"

Because three rises and four require eight life sources, Fei Lun immediately found that the Wind Hidden Ring stayed at the fourth order, the storage space became eight cubic meters, and the wind blade also became the fourth order.

"Huh!"

Fei Lun's mind moved slightly, and his left hand wearing a hidden ring suddenly made an explosion out of thin air, and then the standing trees a few meters away in front of him suddenly fell to the ground in pieces, until they slipped down and broke more than twenty trees before resting.

It's a pity that after seeing this scene, Fei Lun pursed his lips and came out with two words: "Trash!" ”

It is indeed rubbish, because the explosion is a sonic boom, although the speed of the fourth-order wind blade has increased sharply to Mach 15, but such a sonic boom is equivalent to an alarm bell, coupled with the compression of the air flow where the wind blade passes, as long as it is a master, it can be calmly avoided, not what garbage is.

But it didn't matter, and what made Fallon frown even more was that the X series had not yet been opened.

In fact, the fourth-order wind blade or something Fei Lun really couldn't look down on, but the storage space became larger, which made him feel a sense of joy, but in the blink of an eye, the progress of the newly fused ring reached four-tenths, and the X series has not yet been opened, which makes people a little unbearable, after all, according to this progress, there are still sixth-level rings that should be upgraded to the top, and the later this X series is opened, doesn't it mean that its upgrade potential is lower? Isn't it equivalent to a chicken rib!

Fei Lun suddenly felt that this so-called dark gold-level item was a bit unworthy of the name, hesitated slightly, took out all the life sources in the Wind System Hidden Ring, and then ingested it, and immediately heard another upgrade message: "The latest absorption of fourteen points and seven life sources, plus the residual reserve of two points and four life sources, the Wind System Hidden Ring has been upgraded to the fifth order, and the progress is five out of tenths; The ring concealment function cannot be upgraded; The storage space was upgraded to 16 cubic meters; The wind system is upgraded to the fifth level, the fifth-order wind blade, twice the speed of sound, and the sonic boom effect is halved; The X series is opened, the pseudo-supernatural powers, the thunder flash, and the ring is renamed the Wind and Thunder Hidden Ring! ”

"Thunderbolt?!" Fei Lun muttered about this so-called "pseudo-supernatural power", and as soon as his mind moved, he suddenly felt that the surrounding scenery was blurred in an instant, and his body seemed to penetrate countless trees in an instant......

After the surrounding scenery returned to normal, Fei Lun was shocked to find that he was no longer in the same place, and immediately tried to find the way in reverse, and finally found the location of the wind blade cutting the tree a kilometer away, which was the place where Fei Lun originally sacrificed the ring.

Seeing this scene, Fei Lun immediately realized the awesomeness of the pseudo-magic power of "Thunder Lightning", teleporting within a radius of one kilometer, without obstacles......
