The three cities quickly collapsed without the support of the Great Monk of the Yuan Infant Period, and the losses were heavy and the blood flowed like rivers, and after spending half a month, the army also successfully took the three cities.

Su Zixuan took Tianxuan back to Fengqi City in Kyoto, and at the same time, he also let Nan Lingjun Nan Batian take Tianxuan's place, and the three-way army gathered led by Bai Ling to continue to attack the city.

After returning to Kyoto, watching the dragon of luck churning wantonly in the sea of clouds, the unknown aura seemed to have become thicker with the seizure of these cities, Su Zixuan didn't think much about it, and returned to the palace secret room.

"Xuzun, these seven Yuan Infant Great Monks, I don't know if there is a way to deal with it?"

"Oh, seven...... Rong Benzun thought about it......"

A moment later.

"Yes, I have a secret technique that can refine their Yuan Infant Sacrifice into a magic weapon, although their cultivation is a little low, but it should be enough, but this sacrificial refining method is a bit bloody, but ......"

"But what?"

Su Zixuan couldn't wait to ask.

"Hey...... Naturally, the effect is still good, it is still a magic weapon with growth, and it can be used to absorb evil qi, once it is refined, it can be regarded as a very handy magic weapon!"

"So powerful?" asked Su Zixuan as he looked at Yu Zun with suspicious eyes.

"That's it, but these seven people's cultivation is too weak, I think I used a lot of ...... back then."

Humble.

"It's useless to tell you, this is the refining method, you can see for yourself!"

Su Zixuan rolled his eyes and replied, "Okay!"

Then...... Yu Zun told Su Zixuan about the refining method.

Su Zixuan said silently: "Seven Evil Battle Heavenly Ring!"

Of course, the materials needed for this are naturally expensive, but fortunately, after so many years of campaigning, some of them have been collected, many of them are still obtained from the Ghost Spirit Gate, and some are obtained from other places, and there is nothing missing after a closer look.

"Hey...... In that case, let's give it a try!" Su Zixuan said to himself.

Then he studied the refining method, but it was not difficult to erase the divine consciousness of the seven monk Yuanying after refining, and inlay them in it.

After about three or four hours, Su Zixuan also studied thoroughly, so he took out the materials and threw them into the furnace in batches.

As the color of the flame became more and more red and bright, these materials began to melt slowly, and a lot of impurities appeared, so Su Zixuan easily removed the impurities.

Seven days of hard work passed, these materials mixed into one and also became extremely black, like a ball of water vapor, seeing this, Su Zixuan shaped these materials into a ring, and let the excess material that had melted into water vapor a little, wrapped the black ring, water vapor along the original pattern of the ring, little by little flow, after a while, the black ring was completely dyed into a pitch-black color, and the black pattern flashed a rather strange light.

The sound of rubbing came out, and he injected mana into his hand and flew towards the wall, and a deep hole appeared on the wall, fortunately there was a system to protect it, otherwise if it continued like this, I am afraid that the secret room would collapse, but this is still a semi-finished product, and it has not yet been formed.

Su Zixuan spent another few months, studying and continuing to exercise.

......

More than a year has passed, except for resuming cultivation for a period of time halfway, or if there is something that needs to be asked to be respected, Su Zixuan basically did not take a step out of the secret room, and has been immersed in the refining weapon.

This time, when Su Zixuan was looking for something in the package, he suddenly saw an unknown ore, maybe he was negligent in front and didn't see it, but now he suddenly saw it and wanted to ask for an understanding.

"I've found an unknown piece of black ore and want you to see it!"

"Naturally, during this time, I saw that you insisted on refining the weapon and didn't come out, but it looked good, so I didn't say anything, okay...... Bring it to me and see it!"

Su Zixuan took out the black ore.

"Hey, the Black Shine Magic Stone, it's not common! and it shouldn't be on your interface!"

"What is the Black Yao Magic Stone?" Su Zixuan asked a little curiously. ”

"This is actually a rather hard ore with a hint of demonic energy, which is quite useful when forging magic weapons, it can enhance the strength of magic weapons, and it will also suck blood evil qi. ”

"What's more, it's not easy to melt, just like you are now, it won't melt for a few months, if you add it to that ring, it will definitely be useful!"

"Okay, I got it!"

......

Since it can be strengthened, it is quite appropriate to use this object to sacrifice, and after thinking about it, he threw this thing into the black Dan furnace, and while controlling the flames, he also consulted what refining experience.

In this way, Su Zixuan slowly waited for the Black Yao Demon Stone to melt, but the first few seemed to have not changed in the slightest, and it was not until the second month that the stone began to slowly have a melting feeling.

didn't think much about it, so he continued to urge the fire of the Yuan Infant and continue to melt!

......

Another month passed, and the Black Yao Demon Stone that had been smelted by the Yuanying Fire began to appear impurities, Su Zixuan naturally didn't dare to be careless, so he removed the impurities, and then urged the Yuanying Fire more carefully.

According to Xuzun, it will take at least a few months, and now three months have passed, so every step must be subtle and cautious, otherwise the hard work of these months will be in vain.

......

Seeing that the impurities were removed little by little, and the ore began to liquefy a large amount, Su Zixuan quietly observed, while carefully removing the newly appeared impurities, and in this way, half a month passed.

It didn't take long for this piece of ore to be completely liquefied, and the impurities did not flow out, and even became a little black and shiny, which is probably already good, Su Zixuan thought so.

Then he took out the ring-shaped magic weapon that had been refined for a long time, and there was the most primitive black pattern on the magic weapon, and then the liquid in the Dan furnace was slowly led to the black ring, and the black ring made a slight hum, and the liquid flowed slowly with the pattern shape, and was embedded in the pattern little by little.

It didn't take long for the semi-finished product of the Seven Evil Battle Heavenly Ring to be formed, looking at the more complicated patterns on it, as well as the appearance as black as ink, the bloodthirsty evil qi slowly began to reveal, but this is still a semi-finished product, and it already has such an effect, Su Zixuan is already very satisfied.

At this time, Yuzun's voice suddenly came out: "Yes, yes, that's what it looks like, but this is still unformed and can only be regarded as a semi-finished product......! You have to practice well first, this next step is very important, don't worry......"

"It's... Then I'll sacrifice first......"

"Hmmm......"
