The Iron Crystal of the Sky Wai is an immortal-level material. Jiang Hao summoned the Qiankun Sword Box and put the Iron Crystal into the material area to upgrade his three swords, Chunjun, Sword Wings, and Zhanlu.

In fact, the function of Qiankun Sword Box is a small bug. The system does not allow Jiang Hao to carry the items in the mission world, but can use the sword box to carry the collected swords and materials.

However, the material space of the Qiankun Sword Box is limited, and it can only hold a few cubic meters of things at most.

Next, Jiang Hao is preparing to refine flying swords and magic weapons. This time he refines, he intends to borrow the power of earth fire. First, it can improve the quality of magic weapons, and second, it can save a lot of spiritual power. After all, he wants to refine a lot of magic weapons this time.

As for borrowing ground fire, Jiang Hao is preparing to find an active volcano.

The nearest active volcano is located on Silde Island, Australia's only active volcano, "Da Ben Mountain". Da Ben Mountain is also the highest peak in Australia, standing above snow and glaciers, at an altitude of 2,745 meters.

Jiang Hao flew to Da Ben Mountain in Silde Island. The surrounding coast was steep and the terrain was steep. There were no humans living on the island. Steam could still be seen from the mountain, indicating that the volcano was very active.

Jiang Hao gave himself a fire avoidance technique and used the earth escape technique to drill into the volcano. The inside of the volcano was not completely filled with magma, and there were many gaps. Jiang Hao found a suitable platform at the main crater location.

Even though it is still a hundred meters away from the magma, the temperature here is already extremely high, and the strong heat waves and sulfur breath are felt.

This time he has to refine many magic weapons, so he needs someone to help find the purple gold gourd and release Chukura and Sadako.

"Ah, where is this, is hell?"

"It's so hot, I feel like I'm going to burn."

The two girls screamed in shock as soon as they came out.

Jiang Hao quickly gave them a fireproof method, and Hakura and Sadako felt that it was okay.

"This is an active volcano. I am going to refine a few magic weapons, and there are also yours. I'll ask you to come out and help." Jiang Hao said to the two women.

"Sir, please give me instructions." Chuchun said obediently.

"Do you still need to prepare magic weapons for us? Thank you so much." Sadako gave her a smile.

Jiang Hao took out all the materials from the space and put them outside, with enough iron essence, copper mother, as well as golden sand, Xuanxing stone, warm jade, and finally the Nine Heavenly Iron.

Jiang Hao first used copper mother and warm jade to melt into several talismans, and carved the fire-gathering array on it. After the talismans were made, Jiang Hao waved his hand and threw it above the lava pool, and made a magic trick, and the formation immediately started to operate.

I saw a red hot air sucked up from the magma pool. Then, with the transformation and blessing of the fire gathering array, the original red flame continued to change its color.

Orange turns white, white turns cyan, and cyan turns purple.

Jiang Hao knew it was OK, so he threw the Nine Heavenly Iron into the flames and controlled them with object control, allowing the purple flames to burn continuously.

Then he threw iron essence, copper mother, golden sand and other things into the fire, and quenched the flame to remove impurities to obtain the purest materials.

If Jiang Hao had all used spiritual power to complete this life, he would probably be exhausted and would take a long time. Now he would use earth fire to refine it, so he would naturally achieve twice the result with half the effort.

However, his materials are indeed a bit too many, a few tons of iron essence and twenty or thirty tons of copper mother, which is unimaginable to others.

After a busy day, after purifying one-third of Jiang Hao's spiritual power was consumed, and he did not dare to consume the true energy of the Nascent Soul too much.

"Shun Chun, Sadako, come and help me." Jiang Hao said.

"It's an adult."

The two girls rushed forward.

"Sashiko, please help me control the Nine Heavenly Steel Iron. We must continue to temper and not interrupt it." Jiang Hao said.

"Okay sir."

Sadako took over Jiang Hao's work, used matter-control techniques to control the Nine Heavenly Iron, and continued to burn and temper it in the fire-gathering array.

After all, it is a spiritual tool-level material, and purification is more troublesome and takes longer than low-grade materials such as copper mother.

"Early spring, come and help me restore my spiritual power." Jiang Hao said.

A faint shy joy flashed across the face of Chuchun.

"It's an adult."

On the mountain wall, Jiang Hao had already taken out a cave to cover up the temperature. After the two of them walked in, Chuchun took the initiative to come forward to serve.

With the dual cultivation technique, Jiang Hao's spiritual power is quickly replenished, and his cultivation in early spring is also growing steadily, and he can also enjoy endless joy and beauty.

Sadako saw that Chukra was taken away by her master, and she felt a little taste and jealousy in her heart, but she did not dare to question her master, but she was just jealous of Chukra.

It doesn’t matter, the master is a very fair person, and it’s me next time. I have to work hard and complete the work assigned by the adults.

When Sadako thought of this, she began to work extremely seriously.

With one dual cultivation, Jiang Hao was happy and relaxed in body and mind, his spiritual power was full, he returned to work and continued to refine the remaining materials.

Another day later, two-thirds of the material was extracted, and Jiang Hao needed to rest again. This time, he asked Sadako to come into the house with him. Sadako lowered her head and followed closely behind with a small step.

Soon, the two souls and souls were in harmony, and Jiang Hao was operating the dual cultivation method. Sadako couldn't help but tremble, and their spiritual power quickly recovered and increased.

In three days, with uninterrupted efforts, all the materials were purified and they could be used directly as materials and taken at any time. As for the piece of nine-day iron, it completely turned into a pool of red liquid during the three consecutive days of tempering of the purple flame.

That's this time!

Use matter-control techniques to separate the ball of liquid. The largest two balls are naturally used to refine swords. The smaller three balls are used to refine magic weapons for Xiaoqing, Sadako and Chuchun.

He shot a magic trick at one of the balls. The liquid quickly turned into a sword form under the control of spiritual power, forming a sword blank. Jiang Hao threw two taels of golden sand into it and began to constantly penetrate the formation.

Flying array, rapid curse, sword control curse, solid formation, spiritual attraction formation...

When laying out arrays of magic weapons, the effect is no less than the quality of refining materials. Some magic weapons have good materials, but less arrays are still powerful, just like Fantian Seal. Nothing else, it is just a smash.

Some magical materials are ordinary and can be continuously blessed by formations and continuously tempered by the master, and can also become a powerful magic weapon.

He entered more than a dozen formation spells to the sword, and finally completed it. Finally, he shot a magic trick at the sword and shouted.

"Shape!"

The appearance of the sword changed again, this time it became more delicate, becoming what Jiang Hao expected. At mid-spring, Sadako looked at all the master doing, and only felt that the master was so powerful.

Soon, the sword was shaping. Jiang Hao waved his hand and the sword flew towards him quickly and stopped in front of Jiang Hao.

I saw that the sword was silver in general and the sword body was slightly narrow. It was obvious that it was a sword used by women. The swallowing mouth was a white tiger, with golden patterns shining on the body, majestic and domineering.

"Mid-grade spiritual weapons and magic weapons, after refining them later, they may be upgraded to the advanced spiritual weapons level."

Jiang Hao gave a conclusion after seeing the sword.

Jiang Hao is already very satisfied with his ability to refine a medium-grade spiritual weapon.

Jiang Hao didn't name this sword. He wanted to give it to Bai Susu. Then Bai Susu would give it to him.

Wave your hand and put this sword in the space.

"Hu, I'm really tired. Take a break and recover your strength. Chuchun will come to help me." Jiang Hao said to Chuchun.

"Okay sir." Chuchun happily agreed.

In this way, a few days later, Jiang Hao refined Ma Xiaolin's sword. The special thing about this sword is that it can be stretched and retracted freely. Jiang Hao specially added a formation to use spiritual power to activate the expansion and retract.

The level is also a medium-grade spiritual weapon.

When Ma Xiaoling practices sword control skills in the future, this sword can also become her flying sword weapon.

Later, Jiang Hao refined a set of Wuding Flying Rings, which was for Xiaoqing. The main material was Jiutian iron + copper mother, with Jinsha and Xuanxing Stone, and a total of nine Flying Rings were refined.

After practicing, the level of Wuding Feihuan is a primary spiritual weapon.

The bracelet is gold-copper and has golden runes on it, which looks mysterious and beautiful. Usually, the flying rings are put together and put on the wrist as an ornament. When used, they can be released. The flying ring's action route is unpredictable, making the enemy unable to defend.

Even Hakura and Sadako liked this Feihuan very much.

Finally it was Chukura and Sadako's turn, Jiang Hao asked, "I plan to refine a set of flying needles for each of you. Do you like it?"

"We all like it as long as it is given by the adults." Hakura and Sadako replied with a smile.

Look, how well-behaved.

This is what makes people like.

These two sets of flying needles are all made of Jiutian Craft Iron, without adding anything else, and are similar to the finest embroidery needles.

Although the flying needle is thin, it looks weak and has little lethality. In fact, the flying needle is a very vicious magic weapon.

The flying needle is small, so it is silent and breathless. It has a very strong armor-breaking ability and can also penetrate into places that are not preventable. After the flying needle is pierced into the human body, it will flow all over the body with blood, causing you to feel in pain.

Even cultivators often have fragile inside their bodies.

Hakura and Sadako are ghosts, so it is very suitable for both of them to use flying needles.

The flying needles are small and it is even more difficult to refine. It took Jiang Hao four or five days to do these two sets of needles.

In the end, both sets of needles reached the primary spiritual weapon level.

After refining, Jiang Hao directly handed it to Chukura and Sadako, and taught them how to sacrifice and refine, injected a wisp of soul, and then completely tempered it with spiritual power, and finally entered the body.

It took Chukura and Sadako three days to completely sacrifice the flying needles.

Why so fast?

Generally, it takes a month to sacrifice and refine spiritual weapons. Why do the two women sacrifice so quickly? This has to be said to Jiang Hao's contribution.

He taught the method of sacrifice and refining when he was practicing with two women. He was refining the flying needles himself, and his recognition of him reached 100%. During the process of Jiang Hao and the two women's double cultivation, the spiritual energy blended, and it was naturally very easy to refine the flying needles.

Jiang Hao said to the two women: "The sacrifice is not the end. You need to practice more methods of using it and attack methods on weekdays. I don't know how to use the flying needle. You can figure out the specific tricks yourself."

"On weekdays, you should use more spiritual power to temper magic weapons, so that you can increase the power of magic weapons. Maybe you can go to a higher level in the future and improve your grade."
