When the temperature of the flame reaches more than 1,000 degrees, it is very difficult to increase by one degree.

There was once a Dan master who tried his best to refine some materials with a high melting point. Experienced Dan masters know that there are several levels of flame temperature.

Below 200 degrees, it is called low temperature. More than 200 degrees, less than 700 degrees, called medium temperature.

More than 700 degrees, then it can be called a high temperature.

If it reaches 1,000 degrees, almost all the alchemy materials can already be refined. As for fifteen hundred degrees, even the Sword Master can be burned to death. It is the most difficult to refine meteorite iron, ink stone and other things, all of which can be refined.

At this juncture, Yihuo successfully advanced to the third grade, which really helped Chu Feng a lot.

Because the melting point of the Star Iron Essence is extremely high, if the temperature of the alien fire is 1,200 degrees, I am afraid it will be difficult to refine it in a short period of time.

Now it's different, the 1,500-degree Jiuyang Alien Fire has just exploded it for less than half an hour, and it has already begun to melt. Like a candle, it began to drip.

Chu Feng first dropped the melted star iron essence evenly on the sword body of the Demon Slaying Sword.

And then supplemented with Mithril and the like.

The last step is to use Tianhe Luo water to quench it.

As Tianhe Luoshui was tempered, I saw that the star iron essence and other coatings on the surface of the demon slaying sword body were slowly absorbed by the sword body. The tiny cracks and gaps in the sword's body began to slowly disappear.

......

After a full three hours, all the buckets of Tianhe Luo water were used up. All the materials, all exhausted, no more, no less, just right.

The body of the Demon Slayer Sword, whether it was those tiny cracks, conspicuous gaps, or dark wounds, was all repaired as before. It's even tougher than ever.

Its surface bloomed with a dazzling cold light, and the edge was sharp.

The Demon Slayer Sword has taken on a new look.

"Whew!"

Chu Feng let out a long breath of turbidity, and his face also showed a trace of joy of success. After spending so much money and countless efforts, the first step was finally completed. The body of the Demon Slayer Sword will be completely repaired.

You don't have to worry about it suddenly being damaged or aggravated when you kill an enemy with it.

The next step is to fix the runes inside it.

The materials needed are more precious, and there is no need to count on them at the moment.

"Zheng Zheng~!"

The Demon Slayer Sword emitted a clear sound, it was extremely spiritual, and after the sword body was repaired by Chu Feng, it seemed to be more loyal to Chu Feng, the new master. I believe that in the battle, the cooperation between it and Chu Feng will definitely be more tacit.

There are still more than two hours left, and he will go to the Sword Asking Platform to fight Qiu Tai.

Qiu Tai's strength was extremely terrifying, and Chu Feng still had a trace of pressure. Because in the process of the decisive battle, it is not allowed to use pills to help the battle.

Otherwise, it is considered cheating.

Chu Feng took a pill and accelerated the recovery of the depleted sword qi and spirit.

Half an hour later, he entered the Valley of Evil Spirits with his sword and practiced the Shura Imperial Sword Technique. Not only is it secret, but there are also natural evil spirits inside, which can be used by Chu Feng to practice swords.

The Demon Eye Evil Spirit King is the boss here, and as soon as it gives an order, countless evil spirits will immediately come to Chu Feng to practice his sword.

In addition to this, the Sword Shadow Worm can also play the role of the best sword slave.

In addition, there is a strong evil qi in the Valley of Evil Spirits, which can continuously replenish Chu Feng's consumption of practicing Shura's sword technique.

I saw Chu Feng holding the Demon Slaying Sword, and in the Valley of Evil Spirits, he kept slashing the evil spirits that pounced one by one.

Due to the presence of altars, they can be resurrected soon.

......

The sword platform was already full of people, and the competitions were also carried out in an orderly manner. Like a Yama, Chutai sat cross-legged in the ring. The terrifying momentum continued to radiate around, and no one dared to approach him at all.

Elder Yang and the others all pinned their hopes on Qiu Tai.

Looking forward to Qiu Tai defeating Chu Feng and then abolishing it.

Of course, there are also many people who hope that Chu Feng will win. Elder Shoumei, Qin Keren, Han Xiaoying and others all hoped that Chu Feng could win.

There is no doubt that because of Chu Feng's big dark horse, his duel with Qiu Tai has become the focus of the audience.

As time passed, Chu Feng's figure never appeared.

"Shou Mei, shouldn't your apprentice be hiding somewhere, don't you dare to come?" Elder Yang couldn't help but mock.

"Do you think everyone is like you? My character is very good!" Elder Shou Mei looked disdainful.

While everyone was anxiously waiting, Chu Feng's figure never appeared.

This time, even Elder He couldn't sit still.

"Go and see, where is Chu Feng, bring him immediately, you must participate in this competition!" Since Elder He has a mind, he wants to suppress Chu Feng or even abolish it.

It would be impossible for him to let Chu Feng avoid without fighting.

The people who went to investigate quickly ran back dejectedly.

"Report to the elder, Chu Feng has entered the Valley of Evil Spirits. There are many evil spirits in it, and the terrain and environment are complex, so it is very easy to get lost. We didn't dare to enter!" This disciple of the Law Enforcement Hall, although his strength is not bad, he will never dare to enter the Valley of Evil Spirits.

Not to mention him, even the sect elders did not dare to enter the Valley of Evil Spirits easily.

"This is a bit difficult!" Elder He's brows furrowed into Sichuan characters, and his face was even more gloomy and cold.

"Hmph, I think that kid surnamed Chu is extremely cunning, and he must be afraid of fighting. That's why I deliberately hid in the Valley of Evil Spirits. Wait until the sect is over, and then he runs out. ”

Elder Huang gloomily poured dirty water on Chu Feng's body.

Yesterday, Chu Feng made him miserable.

Up to now, Elder Luo's eyes looking at him were still cold and extremely unkind.

"Or, Elder Huang will go to the Valley of the Evil Spirit to find out Chu Feng?" "Elder He, as the presiding elder of this sect Xiaobi, his face was also a little unsightly when this kind of thing happened.

was tricked by a small ordinary disciple, and there was nothing he could do, where did this make his face?

When Elder Huang heard that he was going to let himself enter the Evil Spirit Valley, he couldn't help but shudder, shook his head again and again, waved his hand, and said, "Elder He, let's send someone else, I have been cultivating recently, and I have suffered some internal injuries." The evil qi in the Valley of Evil Spirits is too strong, and if I enter, it will easily aggravate my injuries. ”

As he spoke, there was a painful expression on his face, as if he was really suffering from internal injuries.

Although Elder He knew that Elder Huang was pretending, he still tacitly understood it and didn't say anything more.

"I don't think it's possible to have an internal injury? You made a move to stop the old man yesterday, but you were very powerful. Elder Luo grimaced and exposed Elder Huang's lies.

"Hmph, it's not all you who beat you!" Elder Huang looked angry.

Seeing that the two elders were about to fight again, Elder He hurriedly spoke out to stop the two from continuing to quarrel.

He turned his head to look at Elder Sheep.

"Why don't you go to the Valley of the Evil Spirits?"

"The old man's disciples still have a few important decisive battles, and they definitely can't leave. Elder Yang also shirked and refused to go.
