According to the map, Du Fan spent five days touching the refining place of the Fourth Ring, but he did not rush in, but walked around the merchant pavilion outside, and only then stepped into it after purchasing all the materials that were still lacking in refining the sword.

The reason why Du Fan chose the refining place of the Northern Hell Family was because the grade of these two swords was too high, and when refining, they would produce a vision of heaven and earth like the Ghost Luomen, and in a specific refining place, for the privacy of the refiner, a large isolation array for high-level magic weapons would generally be arranged to prevent the breath of the magic weapon from leaking out.

This kind of isolation magic circle Du Fan can also be arranged, but he lacks the formation tools and related materials in his hands, and it will inevitably be a trouble to go to the formation when he collects these things, so it is better to spend some family contribution points that are not of much use to him.

Under the guidance of a Zhuji deacon, Du Fan came to a dark space.

"Senior, this is the highest-level refining room of the Fourth Ring, if there are no other problems, the junior needs to verify the imprint in your identity crystal. ”

Du Fan took out the identity spar and handed it over to the other party to operate, which can be regarded as completing the last procedure of leasing the refining place.

"The lease period of this refining room is fifteen days, and when the time comes, the teleportation ban here will be activated immediately, and all the people and magic weapons inside will be teleported out, so if the seniors need to renew the period, it is best to contact the juniors one day in advance, if the seniors' refining weapons are not completed, they are teleported out, then the losses of the seniors may be very serious. Deacon Tsukiki advised.

"Okay, I got it. Du Fan nodded, indicating that there was no problem.

"The junior will say goodbye first, and wish the seniors success in refining. After Deacon Zhuji saluted Du Fan, he turned around and left the place.

Du Fan's divine thoughts were scattered, and after making sure that there were no hidden dangers in this refining room, he raised his hand and pressed it, and closed the stone door in the air.

......

Ten days later, a blue long sword was suspended in mid-air, the outside of the sword body was crystal bright, hard as ice, and the water inside the sword body was rippling, as if there was a clear spring, one ice and one water, blue and clear, giving people infinite beauty, and there was no lack of brilliant sword power like the night of the day, and it was a supreme sword.

This sword is a combination magic weapon formed by the fusion of the Shangshan Ruoshui Sword and another innate supreme magic weapon.

"When the Shangshan Ruoshui Sword was born, above the sky, eight big characters appeared out of thin air, 'Blue Light Sword Shadow, Shangshan Ruoshui', it stands to reason that the grade of the sword unearthed in the Sanhuan Forbidden Land is higher than that of the Shangshan Ruoshui Sword, but the name has never been revealed, does the fierce brother know what is going on?" Du Fan asked.

"When you encounter that sword, you can't tell how long it has been around, so naturally you can't tell its name, but you can still find its name from its sword intent. Du Fan had a black and shiny hair hanging from his shoulder, and it was from this hair that his voice came out.

"Sword intent, then tell me, what is the name of this sword?"

"Icy cold light. ”

"Ice Spirit Cold Lightsaber...... Well, it's a good name, it's just in line with this sword charm, it's not as good as this refining combination magic weapon, it's also called this name. Du Fan looked at the blue long sword suspended in mid-air, and muttered to himself with satisfaction.

"The Ice Spirit Cold Light Sword is different from your imitation Ghost Rakomon regardless of the grade, this sword is the deity, it has the qi of Qiankun, it is natural, the only fly in the ointment is that the good water sword is broken and rebuilt, otherwise the power of this combined magic weapon can be added a few more points. Wanyan gluttonously said.

Speaking of this incident, Du Fan couldn't help but think of several senior brothers under the Lawless Gate, when he was besieged by a strong enemy in the martial domain of the Yanjiang Continent, the Yin Yang Sword Saint Yan Beigui, Monk Hua and others came in time, and they did not hesitate to expose themselves to the sight of the Nangong family, and they rescued him.

Later, in order to make Du Fan cultivate for great progress, Yan Beigui and others also deliberately took him to the forbidden land of the Nangong family to snatch the prototype of the holy medicine that the family had cultivated for many years, and therefore faced a martial saint ancestor directly.

In that battle, the sky was dark, the sun and the moon were dark, and it was very tragic.

Du Fan's Shangshan Ruoshui Sword was broken at that time, and was later rerefined into an ordinary superlative magic weapon by the fourth senior brother Xun Nanshan with the remnants.

Thinking of these past events, Du Fan couldn't help sighing, he didn't know what happened to his four senior brothers when he said goodbye that day, but the third senior brother old drunkard once said that because of the relationship between the imprints of the same door in the body, if a few of them fell, Du Fan should have sensed it, fortunately, until now, Du Fan did not feel the abnormality in his body, maybe those senior brothers were really auspicious and escaped the clutches of the Nangong family.

But this is unreasonable, between Yan Beigui and the others and the Nangong family, it has reached the point where water and fire are incompatible, either you die or I die, both sides will not give up, and how terrifying the Nangong family is Du Fan knows, even if his senior brothers are amazing, but shaking the family is tantamount to hitting a stone with an egg, if you want to say that the war has not died until now, it is impossible to think about it, so what has happened in these years?

"In this life and this life, since I, Du Fan, have identified the four senior brothers, then no matter what your life and death are, I will go to the Nangong family in the future to ask for an explanation for the master and for you!

I once said that it is the luck of my Du Fan to be able to go to the same door with a few senior brothers, if you live, he will drink and talk together in the future, if you die, I will personally build a Nangong tomb to pay tribute to you......"

In Du Fan's heart, the joy generated by refining the combined magic weapon gradually faded, and depression and heaviness followed.

After a while, Du Fan raised his hand and put the Ice Spirit Cold Light Sword into the Qiankun Ring.

Under the guidance of Wanyan gluttony, the refining process of the combined magic weapon was very smooth, and the original plan of half a month was completed in only ten days, so the rental date of the refining room was still five days, but the contribution points spent were not returned, and the remaining five days could only be wasted.

Du Fan cast a spell and dispelled the magic weapon aura in the refining room, and then left this place.

......

Back at the residence, a person waited outside the door, and after talking, he learned that this person was here to send a "tribute", and the source of this tribute was naturally Star City.

After Du Fan put away a few storage tools, he waved his hand to let the visitor leave.

Returning to the secret room, Du Fan immediately retreated, and while running the exercises to condense and cultivate, he felt the Great Dao and pondered the road after the Danhai Period.

......

A year later, a piece of news spread throughout the Fourth Ring Road area, causing quite a stir.

Among the clansmen with surnames outside the Fourth Ring, those who cultivate to reach the Great Perfection of the Yuan Infant Stage will get a chance to wash the meridians and cut the marrow, which will be of great help to the advanced god transformation period in the future, and this place of washing the scriptures and cutting the marrow is in the first ring, two years later.
