However, if you want to refine the Flying Sword of the Silent Spirit Level Immortal Treasure in this way, it requires extremely high auxiliary materials to provide attributes. It is definitely not feasible if it is just five spirit beads. At least it should be an auxiliary material that is also close to the Silent Spirit Level Immortal Treasure.

Not to mention, there are two treasures in Shen Lang's storage ring suitable for refining wind and water attribute flying swords, namely the Dingfeng Bead and the Haoyin Han Po Bead.

These two pearls are both one of the "Top Ten Spiritual Pearls" in the Five Emperors' Age.

The Dingfeng Bead contains extremely strong wind-attribute energy, while the Haoyin Hanpo Bead belongs to water. The attribute energy in the two pearls is very pure, which is an excellent auxiliary material for refining attribute flying swords.

Needless to say, the Dingfeng Bead is the fairy treasure left to him by Ziying.

As for the Haoyin Cold Soul Pearl, it was the bead obtained by Shen Lang in the early years of killing the giant clam god in the Three Star Cave of the Shake Moon. Since then, he has been using the best fairy stone and various spiritual liquids to warm the bead, barely making the level of this bead close to the level of the Silent Spirit-level Immortal Treasure.

Although it is a little worse than the fixed wind bead, it should be enough to refine water-attributed flying swords.

Since there are ready-made auxiliary materials, Shen Lang only needs to embed the Dingfeng Bead and the Haoyin Cold Soul Bead into two attributeless Silent Spirit-level flying swords to form a set of flying sword immortal treasures that meet the requirements of the second level of the Immortal Killing Sword Classic.

Shen Lang has obtained countless spoils and cultivation resources over the years. The most common Silent Spirit-level Immortal Treasures he collected is the Flying Sword. He soon found two extremely suitable attributeless Silent Spirit-level Flying Swords.

After making up his mind, Shen Lang immediately began to refine the flying sword.

Although Shen Lang's weapon refining skills are average, he only needs to inlaid the Dingfeng Bead and the Haoyin Cold Soul Bead on two Silent Spirit-level Immortal Treasure Flying Swords. The steps are very simple. As long as you are careful during the weapon refining, you should not fail.

Shen Lang took out the Dari Furnace, which was given by Lu Dongbin. The grade has reached the level of the Silent Spirit-level Immortal Treasure, and is an excellent container for alchemy and weapon refining.

Previously, Shen Lang even trained his body in this furnace, which was very reliable.

He threw the two prepared silent spirit-level flying swords into the Great Sun Furnace. Next, he only needed to calcin the two silent spirit-level flying swords to a semi-melt state, and then embedded the Dingfeng Bead and Haoyin Cold Soul Bead in it to complete the refining.

The Silent Spirit-level Immortal Treasure is extremely tough and extremely heat-resistant. Shen Lang cannot burn the flying sword with the ordinary Nine-flavored True Fire.

Think about it, only the star fire released by the Fire-Sharp Spear has this ability.

Shen Lang sacrificed the Fire-Spirit Spear and sealed the Fire-Spirit Spear in the Great Sun Furnace along with two Silent Spirit-level Flying Swords.

After making all the preparations, Shen Lang activated the fire spear and continuously released the starry fire.

The Great Sun Furnace emitted a muffled "boom", and the violent red and golden fire rose out of the fire-sharp gun body, forming a thick vortex of flames in the narrow Great Sun Furnace, madly calcining two silent spirit-level flying swords.

The power of the star fire is extremely strong, and the energy generated by this fire is very easy to penetrate into the objects, which is very suitable for refining weapons.

At that time, Emperor Ziwei refines the fire-tip spear with the Star Fire and the Ziwei Heavenly Fire. It can be imagined that the huge advantage of this Star Fire is used to refine weapons.

Sure enough, the star fire did not disappoint Shen Lang.

In just seven days, the two silent spirit-level flying swords in the Great Sun furnace had been calcined into a red hot shape and began to soften.

Shen Lang carefully controlled the fire spear to release the star fire to avoid destroying the flying sword because the fire was too strong, and maintained the flying sword at a semi-melt balance point and continued to burn for three days.

Finally, the two silent spirit-level flying swords were completely melted and softened.

At the most perfect time node, Shen Lang threw the Dingfeng Bead and the Haoyin Cold Soul Bead into the Great Sun Furnace, and carefully controlled the two pearls with his divine thoughts and embedded them into the hilts of the two Silent Spirit-level flying swords.

After completing the steps, Shen Lang used the fire tip spear to release the star fire and continued to burn the flying sword, so that the Dingfeng Bead and the Haoyin Han Po Bead merged with their respective flying swords.

In another ten days, the Dingfeng Bead and the Haoyin Cold Soul Bead finally fully merged with the two Silent Spirit-level flying swords!

After the energy on the surface of the flying sword stabilized, Shen Lang couldn't wait to open the furnace, took out the two newly refined flying swords, and tried the power.

As Shen Lang expected, the flying sword embedded in the Dingfeng Bead and the Haoyin Han Po Bead contained wind attributes and water attribute energy, and its power was 30% higher than that in the state without attributes.

"Hahaha, it's finally successful!"

Shen Lang held two rebuilt Silent Spirit-level flying swords in his hand, and his face could not hide his excitement.

In this way, all nine flying swords needed to practice the second level of the Immortal Killing Sword Classic were collected.

The nine flying swords are divided into nine attributes: gold, wood, water, fire, earth, yin, yang, wind, and thunder. Although the grade of each flying sword is of the Silent Spirit level, there are still some differences between them.

Although it cannot be 100% balanced, it is also useful enough.

This set of flying swords is named "Jiuxuan Spectral Sword", which is also a tribute to the "Leize Spectral Sword" that Shen Lang refines for the first time in the human world.

After Shen Lang recognized the flying sword as his master, he rested for half a day to relieve the mental fatigue caused by the 20 days of concentration in refining the flying sword.

Half a day later, Shen Lang's energy and spirit returned to a better state, and then began to study the second level of the Sword of Killing Immortals.

In his spare time over the years, Shen Lang has spent a lot of time studying the second level of the Immortal Sword Classic, and has probably figured out the trick.

The second level of the Sword Book of Killing Immortals records two magical powers, one is the primary golden immortal art "Sword Crushing Yin and Yang", and the other is the advanced golden immortal art "Nine-Curve Sword Formation".

Not to mention the sword rushes to Yin and Yang, the Nine-Curve Immortal Sword Formation is very similar to the "Sword Domain" that Shen Lang practiced in the human world.

As his cultivation level improves over the years, Shen Lang can actually better understand the profoundness of the Sword Domain.

In the past, the sword domain magic powers he practiced in the human world today are simple and crude, but their magic powers have many changes in nature and are infinitely mysterious.

Le Feier can even get inspiration from Shen Lang's sword domain and create his own mysterious immortal art. You can imagine the cleverness of the sword domain that cannot be humanely known.

While practicing and comprehending the second level of the Sword of Killing Immortals, Shen Lang activates the Nine Profound Light Sword for drilling.

Thanks to the huge improvement in cultivation level, Shen Lang's control over the flying sword has reached a level of superb level. Within a few days, he practiced the primary golden immortal technique "Sword Crushing Yin and Yang" in the second level of the Immortal Killing Sword Classic.

Although it is a primary golden immortal art, with the blessing of nine silent spirit-level flying swords, the power of this art is shocking, far from comparable to ordinary primary golden immortal arts, and is even much stronger than the illuminated magic light used by Shen Lang in a human form, and it is actually very close to the level of advanced golden immortal arts!
