Seven days later, Gu Shuang had been practicing in the treasury of the Red Devil Palace, and he had devoured all the two billion black beads in the warehouse, and finally let his ontological strength break through to the S-level! It has reached the realm of gods and demons with a speed of kilometers per second!

At this moment, Gu Shuang's strength is S plus S-level! The total strength has fully reached the SS level!

And the combat power, in the case of holding a black knife, is already SSS-level terrifying!

"The Twelve Tiangang Beidou Step has been initially introduced, and the next step is to rely on actual combat to improve! Now, I need to find a way to fix the hole in the black substance! ”

After Gu Shuang sorted out his strength, he got up from the warehouse, turned around and came to the bedroom of the Red Devil before the Red Devil Palace, and his thoughts swept away, and Gu Shuang found a secret door under the Red Devil's bed.

Seeing the secret door, Gu Shuang was overjoyed, and after smashing the big bed with a punch, Gu Shuang kicked through the secret door and walked straight in.

"Treasure room?"

After entering through the secret door passage under the bed, Gu Shuang walked two or three meters away along the passage, and then looked up and saw a plaque with two big characters written on it!

Treasure room!

Seeing this, Gu Shuang pondered for a while, kicked the door of the treasure room with the rudimentary mechanism, and swaggered in, as for those mechanisms, they were completely ignored by Gu Shuang, just kidding, the Red Devil himself was slaughtered by Gu Shuang, how could the mechanism he set up get Gu Shuang?

After entering the treasure room, Gu Shuang was dazzled by the dazzling treasures in front of him and the jeweled aura exuded, but Gu Shuang lacked interest when he glanced at it.

If a money-loving person enters here, he may be ecstatic, but Gu Shuang is not interested in any money at present, when his sister was sick before, he may have been very greedy for money, but now, his sister has recovered and has been taken care of by Ling Hurong for nothing, Gu Shuang has nothing to lose!

"Aren't there some magic weapons and other good things?"

After Gu Shuang glanced at it, he was completely disinterested, he actually overestimated the mutants of the Red Devils, thinking that these mutants of the Red Devil had only awakened for a maximum of sixteen years, so what kind of powerful treasure was there? It's nice to have a good weapon!

Although there are no magic weapons and powerful weapons that Gu Shuang wants in the treasure room, there are quite a lot of rare metals and precious materials, especially those gold and silver things, the whole room is estimated to be worth tens of billions.

After thinking about it, Gu Shuang opened his right hand with his backhand, and sucked the treasures full of treasures into the palm refining, and after a while, a large number of water droplet materials after refining were gathered in Gu Shuang's palm.

After putting the black on his body into the mass core, Gu Shuang began to fuse and repair it little by little, and after about a few dozen minutes, Gu Shuang suddenly found that the black substance could no longer fuse the water droplets turned by those materials!

"What's going on?"

Gu Shuang's mind moved, the black substance was re-transformed into clothes and put on his body, Gu Shuang checked up and down, the big hole in the abdomen of the black substance had been repaired, and the overall material of the black substance had also been upgraded to the bottom of the peak of the SS level, which could provide Gu Shuang's SS-level strength!

But this seems to have reached its limit, black matter

The quality can no longer be improved! 【...@最快更新】

"Is the peak of SS-class the limit of black matter?"

Gu Shuang was thoughtful, at this moment, his strength had been strengthened to the S plus SS level! The comprehensive strength has stepped into the threshold of the SSS level, but it is a pseudo SSS level.

"Pseudo-SSS class! But..."

Gu Shuangyi clenched his fists and sensed his strength, but what made Gu Shuang feel a little sad was that although the material of the black substance had been improved, the energy required had increased several times!

In this case, as long as Gu Shuang uses the black substance, if it is to extract the energy in the mass core for energy, it can also support about four or five hours, but if he extracts the yuan energy in his body for energy, it can only be used for less than ten minutes!

"It's a bit of a pity."

Gu Shuang let go of his hand slightly, and the black substance no longer provided assistance.

The current situation is that the black substance has reached the limit of power, the peak of SS level, and the consumption is very large!

This means that as long as one day Gu Shuang's ontological strength exceeds the peak of the SS rank too much, this black substance will be useless.

"I can't talk too much, maybe it's a matter of materials, when I find more precious materials one day, he may be able to break the limit of the peak of SS rank! Keep me up! ”

Gu Shuang clenched his fists, thinking that he had thought of pulling out the big magic knife on his waist and looking at it.

This big magic knife, which has been with Gu Shuang for a long time, is from the hand of Gongsun Hao, the president of the Eastern Federal Research Institute, and the handle is equipped with a power furnace, plugged in with solid-state energy, as soon as you hold the handle, the whole long knife will be heavier than 10,000 catties, but unfortunately it is a little unable to keep up with Gu Shuang's speed of becoming stronger.

At this time, there are some gaps on the blade of this knife, which can have some dried blood stains, and at the tip of the knife, there is also a crescent-shaped gap, which was bombarded by the particle light energy of the six-winged tengu when he fought against the Six-winged Tengu of the Steel Clan before.

"There are still a lot of droplet materials in the quality core, I wonder if you can help me upgrade this knife?"

Gu Shuang pondered for a while, he was a little afraid, he was afraid that after the mass core was refined, the Great Demon Knife would not even have the shape of a knife, and he would completely lose his original power.

But Gu Shuang thought about it, and finally decided to give it a try, prepare to repair it, and upgrade the Great Demon Knife.

Thinking of it, he did it, only to see that after Gu Shuang took off the big magic knife, together with the scabbard, he let the quality core absorb it.

Almost after a while, the Great Demon Knife and its scabbard were refined into a drop of water, and when Gu Shuang saw this, he summoned it out with apprehension.

As soon as the water droplets turned into the big magic knife appeared, it turned into a long knife with a sheath, the long knife and the original big magic knife still looked the same, Gu Shuang pulled it out and looked at it, and found that the big magic knife was shorter, and the rest of the place was no different from the original appearance,

"Hmm!"

Gu Shuang nodded thoughtfully, and then sent the Great Demon Knife into the mass core, and began to fuse with the water droplets transformed by other substances in the mass core.

About half an hour later, Gu Shuang took out the big magic knife and looked at it, his hand was just right

As soon as I touched the long knife, my pupils shrank sharply!

After many fusions and refining, the big magic knife and the scabbard became unrecognizable, first of all, he lost the function of light and heavy, because the power furnace had been refined, its weight was maintained at about 100,000 catties, one meter six, the blade was straight and red, and the scabbard was blood red, becoming a long knife!

"It's so long! It's so heavy! So sharp! ”

Gu Shuang weighed the big magic knife for a while, 100,000 jin is the weight of a drizzle for Gu Shuang, whose body has reached the S level, but for ordinary people, it is a golden hoop stick! This knife, in fact, it doesn't matter if it's sharp or not, if you throw it away, you can kill a person! What's more, the re-refined Great Demon Knife has reached an extremely terrifying point of sharpness?

However, the knife is too long to make Gu Shuang a little uncomfortable, and one meter six is also too long. Like a knife, it looks majestic, but it is unsatisfactory when it fights.

As if sensing what the story wanted, the length of the big magic knife shrank from one meter six to one meter two, and this length was also the length of the big magic knife that Gu Shuang had just taken the knife.

"Although the weight is not as good as it should be, the size can be as expected, well. There are gains and losses! ”

Gu Shuang took out the big magic knife and stabbed it forward, and with a move in his mind, he found that the blade suddenly changed and grew more than ten meters long, and from one end, it directly pierced through the wall!

"Huh? This...."

Gu Shuang's heart was playful, and after playing a set of shocking knife techniques, Gu Shuang was excited, this knife is really a magic knife!

Carrying this knife to fight with people, fighting and fighting, the blade of the knife suddenly grows and pierces the enemy, and the enemy is estimated to be so stunned that he will not be able to see it!

"Unexpected surprise!"

Gu Shuang was slightly excited, after fusion and refining, the material of the big magic knife was improved, the sharpness was improved, and the weight was increased, although the skill of light and heavy Ruyi was missing, but there was one more size Ruyi, which was an unexpected surprise for Gu Shuang, because the skill of light and heavy Ruyi was a chicken rib for Gu Shuang.

"I wonder who will be the first to die under this knife?"

Gu Shuang hugged the big demon knife and showed a wicked smile on the corner of his mouth, and then left the treasure room directly, preparing to embark on the journey again, go to the Arctic land, find the floating insects, and completely solve some doubts in his heart.

And the moment Gu Shuang walked out of the Red Devil Palace with his bags, killers from all sides gathered! Vowed to kill Gu Shuang!
