Leaving the Soul Martial Star, Chu Xiong, Qing Dai, and Yu moved all the way to the Heart Moon Fox Main Star.

As soon as they left, the three of them felt a little lost in their hearts. Chu Xiong has been pondering, in fact, even if Qi'er and the others can't reach the realm of Xingwu, they can still be with him. The premise is that he can advance to the realm of the Solid Star Monarch!

According to the Taixu Xingjun, when he reached the realm of the fixed current Xingjun, his own space would allow humans to live for a long time. Some extremely powerful solid current star monarchs can even allow a person to survive in their own space for decades. As for the general space, it is already very good to be able to survive for two or three years. In two or three years, it will definitely not be able to meet the requirements of Xingxing.

Therefore, Chu Xiong felt that he still had to be promoted as soon as possible. Instead of pinning your hopes on Bai Suzhen, Youda, and Qi'er to advance to the Star Martial Realm at the same time, it is better to pin your hopes on yourself.

"Look!" Qing Dai's greeting pulled the contemplative Chu Xiong back to reality. "On Chuxiong Star, it seems that the forest is much denser!"

Almost in a flash, it greatly surpassed the area where Chu Xiongxing was located. But Chu Xiong still occasionally glanced at it, and on the star named after him, more green did appear. Although compared to other auxiliary stars, this star is still very desolate. But the speed at which it has developed and spread is really rare.

Subsequently, the three of them continued to move for nearly a year. Along the way, they are all on the lookout for the Gentle Fire Carbon Star.

Originally, Chu Xiong could go to the Wenhuo Carbon Star not far from the Little Fox Star for a maximum of more than a month.

However, Chu Xiong was not very relieved in his heart. After all, he was pressed for time, for fear of accidents. Last time, he had gone all the way to the core of the Flame Carbon Star, which was 400,000 miles deep. Therefore, one year of tempering is equivalent to ten years for others.

And this time, if we find a larger Simmering Carbon Star, will we be able to achieve the effect that one year is equivalent to 15 or even 20 years for others? If so, the time will be more relaxed. After all, the fifteen-year covenant that the Taixu Xingjun and they speculated was also a rough imaginary number. What if the Nine Rivers Star Domain arrived a year and a half early?

Moreover, the last time Chu Xiong went from the initial setting stage to the solidification stage, he spent two years and three months at 400,000 miles. This time, from the setting stage to the fixing stage, the strength required may be greater. It is only in the larger and deeper Simmering Carbon Star that the time is not extremely extended.

It's just that there are not many simmering carbon stars. This star was originally a Wuhuo carbon star (star), but it has reached the stage of decay. Although there are many stars in the starry sky, they are basically martial fire carbon stars. Only after there is a great attenuation inside and the temperature drops a lot, can it be called a simmering carbon star, and then it can be tempered by Xingwu. Otherwise, if you directly enter the Martial Fire Carbon Star, you will be completely burned to ashes.

Therefore, even after more than three years, the three of them still did not find a single Wenhuo carbon star. And one day a few months later, Chu Xiong's eyes lit up. Because not far ahead, a huge carbon star that was not flashing black light appeared in the eyes of the three people.

"God, you're not fighting the idea of this simmering carbon star, are you?" Qing Dai covered her mouth and exclaimed, "This ...... Although this can also be called a 'simmering carbon star', it is also too exaggerated!"

Of course, Yu was also shocked. It's just that Chu Xiong, who has always liked challenges, has a feeling of eagerness to try.

The decay of the Wuhuo Carbon Star into the Wenhuo Carbon Star is an extremely long process. However, there is a very clear cut-off point - that is, the black matter on the surface of the carbon star exceeds 30% of the total area.

And remember the last time I passed through here, that number had not yet been reached. After more than 10 years, it barely reached the standard of 30 percent. So, this huge star can also be called a simmering carbon star - but it has just become.

Obviously, the temperature of such a simmering carbon star is much higher than that of an ordinary simmering carbon star. What's worse is that the size of this simmering carbon star is too huge!

The one not far from the Little Fox Star has a diameter of 800,000 miles, which is already quite small. The one in front of me has a diameter of four million miles, which is five times that of that one. As for the total volume, it is at least a hundred times that of that one!

"It doesn't matter, at least the temperature on its surface is not up to the core of the original one. Chu Xiong smiled, "I'm not inexperienced. If it doesn't work then, I won't go any further. Even if it is at a depth of four or five hundred thousand miles, it can be tempered. So, it's up to me. ”

That's right, who said you have to rush into the core of the carbon star. However, Qing Dai had some abnormal looks.

"What's wrong?"

Qing Dai shook her head and said, "I...... It seems that we are about to touch the bottleneck of the initial setting stage!"

This is a great event, and Chu Xiong is not worried about his lack of equipment. A quenching pill can support him in the Gentle Fire Carbon Star for three years. The remaining 40,000 star sands can also support four years.

Of course, Qing Dai's safety is the most important, Chu Xiong decided to keep 35,000 Star Sand for himself, and give Qing Dai a Quenching Pill and 5,000 Star Sand in case of emergency. Normal star martial arts tempering is mostly one or two years, and it is very unusual to reach three years. Although Qingdai's qualifications are good, they will not reach the strength of Chu Xiong. So, they each prepared three and a half years.

Only Yu sat quietly in the void far away from the carbon star, and had an epiphany alone. Danwu's cultivation and advancement do not need to be tempered, but only their own perceptions. And now she is already a mid-level Danwu, and she is still far from advanced.

Chu Xiong pulled Qing Dai and directly entered this huge simmering carbon star. The surface temperature of this carbon star is much higher than the one next to the little fox star. Especially Qingdai, the first time I entered this terrifying environment, I was still a little nervous.

After going deeper into it for seventy or eighty thousand miles, Qing Dai felt a little panting. The temperature, the pressure, all reached a limit that she could bear. In fact, the temperature of this Wenhuo carbon star is too high, and the temperature and pressure of 70,000 or 80,000 li in it are already equivalent to the level of more than 100,000 li of ordinary carbon stars.

However, Qingdai still gritted her teeth, and went far deeper, until it was 100,000 miles deep, and finally she couldn't move forward anymore.

As for Chu Xiong, there is still a lot of power to spare. He paused and said, "You can refine here, in fact, it is already equivalent to the 200,000 miles of the previous carbon star, and it is not simple." I'll dig a little deeper and try to get the most out of it. ”

So Qing Dai sat down quietly cross-legged, letting the powerful carbon star refine her body to the extreme. And Chu Xiong continued to gallop inside, all the way to the depth of 300,000 miles!

"The temperature and pressure here are already stronger than the core of the previous carbon star for 400,000 miles!" Chu Xiong felt very satisfied with this effect. But he was still not satisfied!

100,000 miles......

50,000 miles......

30,000 miles......

Finally, he went deeper into it for another 200,000 li! At this time, the depth had reached 500,000 li on the whole. As for the temperature and pressure, it is definitely twice as high as the previous carbon star core!

And after arriving here, Rao is Chuxiong's cultivation and physical strength were extremely perverted, and it was difficult for him to continue to walk inside.

"Yes...... It's okay!" Chu Xiong panted. Unleashed his breath, and suddenly a large amount of energy poured into his body. The powerful fire temperature is like a steel-making furnace scorching the body, and every skin and every cell is accelerating its metabolism. And the newly generated body tissues are much stronger than the original metabolism.

It took a full year for Chu Xiong to fully adapt to the temperature and pressure. In this case, just like last time, he took out Qing Dai's moon bow and a Ding furnace of Yu. The name of this Ding furnace is "Tianxin Ding", which is an alchemy gift from Qingliu Danjun, which can be called an artifact. Like ordinary artifacts, they can also be upgraded through the refining of carbon stars to become a super artifact Ding Furnace. And only the Super Artifact Ding Furnace was qualified to refine a higher-level Heavenly Pill.

I remember last time, he was refining this big dragon knife at the same time in his "leisure". However, this time the situation was different! The reason was that the fire temperature here was too high, and the quality of the Falling Moon Bow and Tianxin Ding was not as good as the original Great Dragon Sword. So much so that once the two artifacts were taken out, they were almost melted. Last time, the Great Dragon Knife became almost jelly-soft as soon as it was taken out, but this time these two artifacts simply turned into two strands of fluid, and it is estimated that they will be completely destroyed if the slightest external force is exerted!

In desperation, Chu Xiong took out a large amount of star sand and threw it into the two artifacts. Using the cold to yin qi of the star sand to alleviate the high temperature of the carbon star, this is also a common means when refining artifacts.

As a result, the Falling Moon Bow and the Tianxin Ding were stabilized slightly. And Chu Xiong immediately took out the larger piece of Xingchen Heart Iron and integrated it into the two artifacts respectively. Gradually, the Falling Moon Bow and Tianxin Ding began to harden gradually, and the quality was also improving rapidly. Of course, this is also a long process.

A full year and a half have passed, and the two artifacts have finally taken shape! At this time, the Moon Falling Bow and the Tianxin Ding, even at the depth of 500,000 miles of this super-large carbon star, are only red all over, but their stiffness can be maintained. This grade has obviously surpassed ordinary super artifacts. From the bodies of the two super artifacts, Chu Xiong felt two completely different auras.

The moon bow is becoming lighter and smarter, and you can even feel the turmoil of your mind when you pluck the bowstring;

Tianxin Ding is even more atmospheric, and its steady aura makes people believe that it can withstand the refining of any elixir.

The grade of these two super artifacts, even if they are not as good as the current Great Dragon Sword, must be extremely close. After all, tempering at this temperature and pressure is unimaginable to ordinary people.

At this time, Chu Xiong had to sigh that the original divine envoy Zu Jia was able to have such an artifact as the Falling Moon Bow. You know, not all artifacts have advanced qualifications. Some things are artifacts, but their potential has been exhausted. Even if it is tempered by the carbon star, it will not improve in the slightest. After all, Tianxinding was a gift from Danjun, and it is understandable that he can have high qualifications. And it is really an outlier that the mere divine envoy Zu Jia can also get such an artifact.

Of course, I have to sigh at the bizarre fate. The original Falling Moon Bow killed Yuqi, but the souls of Qingdai and Yuqi finally merged. And then, the bow became her weapon.

It's just that the only strange thing is that in this place where there can be no life at all, he actually felt a faint, but somewhat familiar, aura. The aura was deeper than the Carbon Star, but he couldn't get in.

It must be an illusion!

Chu Xiong carefully put the Moon Falling Bow and Tianxin Ding into his own space, and then went all out to attack his final advancement. It's been two and a half years, and the conditions here are already equivalent to 50 years of refining at 100,000 miles of ordinary carbon stars! Because every year of refining here is equivalent to 20 times that of other places!

Of course, Chu Xiong was also secretly glad that he had made the right choice. If it is still in the original Gentle Fire Carbon Star, even if it is still in the core, then it will not be able to be successfully tempered in five years. Because of the conditions there, it was only ten times the effect of ordinary star martial arts.

And if it can't be tempered in five years, wouldn't everything be delayed, and it would be tantamount to losing trust to Qingliu, Hao Mo, Taixu and others.
