The top floor of the copper tower. The reason why we say the top floor is because there is no passage to the higher level, only dense lines carved on the four triangular sloping walls, converging towards the top, as if deep into the sky under the cover of a cloud of red light. In the corner of the floor, there are some miscellaneous items scattered together.

Barr picked up a yellowed booklet from the pile of debris and opened it to see a few lines written on the first page.

"Originally, I prepared a 'gift' to deal with it, but I couldn't complete it due to time constraints, so I had to sleep and leave, but it was a good gift. I hope that my prophecy will come true, and that the suit will be activated by the blood of eternal life... Zhangqiu"

Barr felt that this beast relict civilization was not happy to do things. Then I turned to the second page of the booklet, where a humanoid pattern was scrawled and the words "Copper Feather, Between the Three Towers" were written in the words "Copper Feathers, Between the Three Towers".

Besides, there was nothing else of value in the clutter pile, except that for Barr, who didn't care about copper coins, the pile was mostly copper.

Return to the ground floor along the way. Now Barr has to think about how to get out of here.

He didn't want to go back to that disgusting, sour hole of flesh, and he didn't find a passage to the surface.

"Well, the Beast Relic must have their normal passage. With their level of civilization, if it were me, I would definitely connect the three towers from the ground, Barbara, what do you say?"

"Tsk. Barbara nodded.

"Then let's go to the west and look for it. ”

After a while, Barr and Barbara stopped at the end of a road, for no other reason, there were three sixteen-digit matrix arrays, A multiplied by B equals C, and C had no answer, and in a small grid next to the passage, there were more than three hundred small square copper plates neatly placed, one side protruding, and the other side was symbols.

"It's matrix operation again, do they have to calculate every time they go out?" Barr was a little depressed, but soon understood why the beast relict civilization was developing so rapidly, and it seemed to be due to their almost crazy learning atmosphere. "Yes, send yourself an arithmetic card, so naturally you don't have to calculate it yourself every time. ”

Baal's frustrated finger was on the ground and the hexadecimal system of all evils had slowed him down. When he raised his head to fill in the answer, 10,000 divine beasts roared in his heart, and the "A" and "B" had become two other sets of data at this moment.

"Key, come on, I'm too slow. ”

With a cup of tea, the west wall rumbled open, a wave of heat rushed in, and a long ladder winded down. Barr and Barbara dodged into the hallway, and the door behind them closed on its own.

The descending staircase is a bit deeper than when you entered it earlier, as can be seen by the distance between the road below and the lava. Without the cooling of the Roshan creatures, it was a lot hotter here.

But what made Barr feel strange was that the strong and disturbed magnetic field here, the Key of Inheritance could clearly detect his strength.

Turning a corner, even though Barr was well-informed, he was still attracted by the scene in front of him. The circular tunnel of the neat section is lined with brass, and the black and red magma flows from the central dark river, emitting a powerful magnetic field, and the pulling force is transmitted from the iron ring on Bal's hand. Barr plucked it off, and it swooped into the river.

In the center of the copper lining, a neat row of huge copper pillars hangs upside down above the dark river. If you look closely, you can see that the copper pillar is not a real copper pillar, but is made of copper wire. On top of the copper pillar, a little lightning occasionally erupted.

"Using the flowing magma magnetic field to generate electricity, such a large scale, this is the main power supply of the three towers, and the steam engine outside is a disguise. Barr and Barbara walked forward slowly, their hair standing on end, looking ridiculous.

But the further they went, the more strange the magma became, and they kept passing through the copper pillar, and after being channeled by the electric field, according to the strength of the magnetic force, they formed a light and dark alternating beam like colored red, and the lightning above the copper pillar became more and more frequent. This means that the power is even stronger here.

Eventually, the magma flows into a lava lake, in the center of which is hung by three copper pillars and a copper platform is swirled to form a whirlpool below the platform, flowing into the ground and going nowhere.

On the opposite side of the copper platform, the same magma tunnel, with iron pillars on the cylinder wall, points to the west.

The road between the two sides of the river was connected by a copper bridge to the copper platform, and in the middle of the copper platform was another black high platform, on which a strange machine glowed blue, and a dark golden humanoid device was suspended in the light.

Seeing that the object was similar to Zhangqiu's hand-painted, Bar called out his name and understood the meaning of the words "Copper Feather, between the three towers".

"Gifts, prophecies, the blood of eternal life..."

"This gift seems to be mine. ”

Barr didn't know what was the magic of the bronze feather that Zhang Qiu wrote down separately before leaving, but since it was placed here, he might as well find out.

So, he flew up and landed firmly on the high platform, and after looking around, he found no mechanism similar to collecting blood samples. After pondering, Barr grabbed the claw of his left hand in the palm of his right hand, and cut a hole in his hand, and blood gushed out. With a wave of his hand, the blood flew to the "Copper Feather Crown" without hindrance.

The blue light that shrouded the "Copper Feather Tree" immediately turned red, and the three surrounding stigmas flashed with electric light, and then the strange machine let out a soft sound, and a soft voice sounded, "Hello non-attenuating metabolic cells, immortal bloodline." ”

Then, a woman's face appears on the head of the "copper feather", which is somewhat similar to that of contemporary people, but the ears are more pointed, and the facial features are delicate and coordinated, giving people a sense of beauty. The robot in the tower who had been talking to Baal and the others finally saw their true faces.

The red light flickered on the "Bronze Feather", and then suddenly turned to shoot at Baal.

Barr didn't dodge, letting the red light sweep over him, and then he saw the woman nod in satisfaction and disappear.

The "Brass Feather" then wriggled and deformed, turning into a ribbon that floated towards Baal and into his clothes.

Barr could feel a chill spread over his body, eventually forming a film covering his entire body, like a new layer of skin, tough and breathable, but insulating from the heat.

It was a treat, and the film slowly covered his head, carefully bypassing every hair, turning Baal into a dull blonde.

As the membrane covered the cervical vertebrae, a thin needle suddenly pierced, and Barr woke up abruptly.

"Illegal programs invade the central nervous system. The Key of Inheritance immediately issued a warning.

"It's okay, the garment is binding to my neurons. "Because the Key of Inheritance is incompatible with clothes, only Baal's own brain can sense what happened after the prick. This is also because he has a slight level of cultivation, and he can feel the detailed changes in the cells and molecules of his body, so he dares to be so sure.

"Nice, almost perfect blend. What's your name?" the soft voice sounded again, and the image of the woman appeared again in the position of the "Bronze Feather", this time wearing a white feather dress. Then she snapped her fingers anthropomorphically, and the central platform began to slowly shake, collapse, or shrink.

"Barr. ”

Baal's mind moved, and he flew down on the bronze platform, and the dark gold color was immediately hidden, revealing his true face. "Barbara, bite me. ”

When Barbara heard this, her face turned happy, and she unceremoniously bit down on Barr's arm, and then let out a scream of "chirp".

I saw two rows of shallow tooth marks on Barr's arm, which recovered in an instant. "Nice nano or sub-nano clothes, this should be a derivative application of Iron Fire Beast technology. ”

"The Copper Feather, bionic copper skin, is more advanced than bionic iron, can control the form through the mind nerves at will, and is designed to be used as a spacesuit and flight suit, and you will know the benefits of it in the future. The female voice continued, though the shrunken platform and the machine had made her form a little different.

"Ruyi rod, the copper feather processing instrument is shrunk, the bionic nano-iron arrangement technology, the built-in strong arrangement of the plutonium nucleus, can continuously supply energy for the copper feather for 100,000 years, can change the form, a good melee attack weapon, Barr, take it away. The woman said the last word and disappeared suddenly. The central black platform had now shrunk into a five-foot-long, two-inch-thick iron rod, carved and engraved, standing in the middle.

When Barbara saw that Barbara had got his clothes, she jumped up to the iron rod and curled her tail out.
