Zhang Tianfeng has been appraising it for a long time and can't put it down.

It can improve the escape speed of a small level. This kind of flying magic weapon is rare in the world of immortality.

Even with Zhang Tianfeng's knowledge, he was a little moved.

True Monarch Black Feather was able to control this wing, initially because the main material of the flying wing had greatly degraded in spirituality and quality over the years. Later, it was activated and nurtured by his bloodline for hundreds of years, allowing it to exert considerable power.

"Transforming [Black Sky Wing] so that it can exert its true power, Daqing's fourth-level weapon refining master, I'm afraid no one can do it."

Zhang Tieshan pondered, seeming a little embarrassed.

"If you have any difficulties, fellow Daoist Zhang, please speak up."

Lu Changan's eyes flashed, and he calculated that there was some hope on Zhang Tieshan's side.

With hundreds of years of friendship and understanding, and enough information media, he had almost deduced the secret of Zhang Tieshan's chance.

"Zhang barely has a transformation plan, which is suitable for wood-type practitioners with strong cultivation abilities. However, it requires the ancient treasure-accumulating secret technique of "Building Heaven and Inspiring Spirits"."

"This secret technique helps to nourish and cultivate the spirituality of the magic weapon. It may even give birth to a weapon spirit. It is of great value. Zhang obtained it from a senior and cannot easily pass it on to others."

"Of course I won't let Fellow Daoist Zhang do it for free."

Lu Changan expressed his understanding.

He was fascinated by the "Spirit-Building Technique".

There is a slight possibility of giving birth to a weapon spirit, which involves the top secret of the weapon refining inheritance of refining true spirit treasures.

This method can help him cultivate the spirituality of the magic weapon and perfect the inheritance of the treasure talisman.

Zhang Tieshan's transformation plan is biased towards the method of refining weapons, and even contains some principles of refining spiritual treasures.

This is in line with the bloodline of Lord Black Feather and the secret method of controlling beasts, which is a completely different approach.

Once successful, the transformed and improved Black Sky Wing will not only be able to exert its power to Lu Changan, but also to Diyan Lord and other monks.

At that time, it will be a universal flying magic weapon.

Lu Changan guessed that Zhang Tieshan already knew that he would have to lose his life to practice the Evergreen Technique and use the Secret Technique of Evergreen to regain more spirituality.

Therefore, this transformation plan is suitable for Lu Changan. Other monks cannot do it, or the price paid is too high, and the gain outweighs the loss.

The two experimented for a while, and Lu Changan stopped talking nonsense and took out a lot of fourth-level and above items and resources from the space props.

"Zhang Daoyou, see for yourself what you can use."

Based on past transactions, Lu Changan guessed Zhang Tieshan's approximate needs.

Deep-sea rare minerals, top-grade magic weapons, fourth-level shells, demon king materials, monster parts...

Zhang Tieshan looked at it hurriedly and couldn't help being secretly shocked.

The quality of these materials may not be particularly high, but they are rare in Daqing.

For example, a few pieces of sea mines and shellfish have disappeared in Daqing, but they contain certain ingredients that Lingbao lacks.

Including the top-grade magic weapon produced by Lu Changan, it also contains unique products from the coastal area.

"I'm afraid it won't be easy for Daoist Lu to collect these materials and magic weapons alone."

Zhang Tianfeng has a profound saying.

Lu Changan has sold stolen goods to Zhang Tieshan before, so there is no need to avoid taboos:

"Lu knew a friend who owned a fake spiritual treasure. He once teamed up with him to kill the enemy Nascent Soul. Unfortunately, one of the Nascent Souls escaped from his body in the middle stage and could not be completely killed. Otherwise, there would be more materials today."

"Pseudo Spiritual Treasure? Kill the mid-stage Nascent Soul?"

Zhang Tieshan's eyelids twitched slightly, feeling that Lu Changan's words meant something.

Could it be that he guessed his secret and tried to test it?

Zhang Tieshan does not doubt that Lu Changan is exaggerating. In fact, this person is more conservative.

A complete pseudo-spiritual treasure is more powerful than the incomplete spiritual treasure he controls. The disadvantage is that it consumes terrible mana and puts a huge load on the spiritual consciousness.

Even if it is a Nascent Soul cultivator, the Pseudo Spiritual Treasure cannot be used as a regular magic weapon and can only be used to launch a few consecutive attacks.

The main reason is that fake Lingbao does not have the spirit of the weapon and is not as good as the magical functions of Lingbao.

Lu Changan revealed this information to warn Zhang Tieshan not to have any ulterior motives in the weapon refining transaction and to keep it secret.

At the same time, let Zhang Tieshan stand firmly and correctly between True Lord Qingmu and True Lord Evergreen.

"These material magic weapons are useful to Zhang."

Zhang Tieshan carved out a part of it, including several inconspicuous materials and defective parts.

"By the way, Fellow Daoist Lu, do you have any extra Five Elements Earth?"

Zhang Tieshan changed the topic and said cheekily.

After being stared at by Lu Changan for a few seconds, his old face turned slightly red.

As a universal source of earth, Five Elements Earth can be called the rare earth among the materials for refining weapons. Zhang Tieshan can never have too much.

The five elements of soil can be refined through secret methods and upgraded to a higher level.

"There is not much left in the Five Elements Soil reserve, and the demand from fellow Daoist Zhang is too great. The "Sky-Building and Spirit-Building Technique" is certainly precious, but if you keep it in your hands to cherish it, it will not be able to realize any value."

Although the two had been friends for hundreds of years, they were not polite in their bargaining.

After a long time, Lu Changan and Zhang Tieshan finally reached an agreement.

Lu Changan was willing to make up for the Five Elements Earth, but asked Zhang Tieshan to help him upgrade the nail-headed arrow to the ultimate magic weapon.

Zhang Tieshan promised to go all out, but Lu Changan had to deal with the weapon refining materials himself.

The main material of the nail head arrow is soul-nourishing wood. This kind of famous tree in the world of immortality has a very high growth limit.

Lu Changan regards it as a natal magic weapon and has cultivated it with the Evergreen Gong for more than two hundred years. Its quality is no less than the fourth-level top-grade material.

When waiting for the weapon to be refined, Lu Changan will invest some more longevity yuan in an effort to upgrade it to the top quality of the fourth level.

Fortunately, the nail-headed arrow is a small magic weapon and the price is not too high.

In this way, even if Zhang Tieshan's weapon-making skills are lacking, he should have basic protection under the guidance of the weapon spirit.

…

After reaching the deal, Lu Changan returned to his dojo.

Both sides need to prepare for this weapon refining upgrade, and some materials are still lacking.

As a master of weapon refining and an elder of the Yuanying Sect, Zhang Tieshan has a large reserve of materials, but it is impossible to do so for free.

Lu Changan said that with his puppet refining skills, he was able to refine a quasi-fourth-level puppet.

Zhang Tianfeng was very moved and was willing to help Lu Changan raise and advance some precious materials.

Lu Changan attached great importance to this weapon refining transaction.

If Black Skywing and Nail Arrow can reach the expected quality, his personal strength will be greatly improved.

Lu Changan had never shot all three nail-headed arrows in a fight.

Therefore, one of the nail-headed arrows has been stored for the longest time and has never been fired for more than two hundred years.

Although after decades of cultivation, the power of nail-head arrows has increased, there is a marginal effect.

But it took too long to accumulate, and the accumulated power was beyond its limit.

It is estimated that after the upgrade, the lethality of the divine soul contained in it will pose a great threat to the mid-stage Nascent Soul in the fourth life of possession, and can instantly collapse the early Nascent Soul.

Lu Changan had never used this most powerful nail-headed arrow, so it was naturally a meeting gift prepared for True Lord Aoki.
