However, a huge amount of resources have been invested in development over the past forty years, allowing the Liyun Bird Shrine's layout in flying spiritual creatures to be fully deployed.

In the future, we can also accumulate resources and develop and live like the Long family.

At this time, the great elder of the Li Yunniao Shrine was really afraid that Lin Yuan would refuse the two rule crystals that were originally promised to him after seeing the things in the Li family's treasure house.

While thinking this, Great Elder Li Yunniaokan did not stop his actions.

The chief elder of the Liyun Bird Shrine directly handed Lin Yuan an album, which was filled with various spiritual objects, spiritual materials, and some source items.

The chief elder of Liyun Bird Shrine said after handing the atlas to Lin Yuan.

"Sir, this collection contains all the current collections in the Liyun Bird Shrine."

"The Liyun bird niche has been seeking development for such a long time, so it may be lacking in collection."

Lin Yuan took the atlas handed over by the great elder of the bird niche, Li Yun, and flipped through it gently.

It is certainly not an exaggeration when the Great Elder of Li Yun Niao Kan mentioned during the transaction just now that a large part of the collection in the Li Yun Niao Kan treasury has been invested in the construction of power.

Otherwise, there would be no need for the Great Elder of Li Yunniaokan to devalue the value of Li Yunniaokan during the transaction.

This does not do the Li Yun bird shrine any good.

But even so, Lin Yuanguang spent a full five minutes just flipping through the fine source items.

This shows how rich the collections of the top forces are.

While browsing, Lin Yuan's gaze paused for a moment on many items.

There are many things that Lin Yuan thinks are useful to him, but he does not intend to exchange them for Rule Source Crystals.

In future transactions with the Li Yun bird shrine, when the Li family no longer has the rule source crystal, I can use the upgraded version of the Golden Lotus Plant to exchange for these things.

Therefore, Lin Yuan's eyes were mainly focused on the supplies that he could not exchange for with the upgraded version of the Golden Lotus Plant.

After Lin Yuan used this standard to look through the atlas, his speed in looking through the atlas became faster and faster.

Even on the mythical second level rule crystal, Lin Yuan did not spend too much time on it.

The Mythical Second Realm Rule Crystal is a good thing, but it cannot reach the level of the peak of the Mythical Second Realm. Even if Lin Yuan absorbs it, he will still need to consume a large amount of Rule Source Crystals to cultivate it.

Including the poisonous rules of the third realm of mythology, Lin Yuan now needs to cultivate as many as four rules.

After the rules were able to increase Lin Yuan's elemental immunity, the cold flame rules that had been ignored by Lin Yuan turned out to be a good thing.

The Cold Flame Rule is a dual-attribute rule of ice and fire, and is a relatively unconventional rule.

But the cold flame rule alone can provide Lin Yuan with resistance to both ice and fire attributes.

Lin Yuan has already raised the priority of the Cold Flame Rules and is preparing to cultivate the Cold Flame Rules well.

The great elder Li Yunniaokan became more and more unsure as he watched Lin Yuan flipping the pages faster and faster.

This album of pictures has almost been completely flipped through. If Lin Yuan really doesn't find the one he likes, then the Li family will be losing two mythical third-level spiritual creatures.

If the emperor-level strongmen do not appear, the spiritual professionals who possess the mythical third-level spiritual objects are already the high-end combat forces among the top forces.

In order to seek rapid development, Liyun Bird Shrine naturally needs to steadily improve its strength while developing its business.

Among the masters in the Liyun Bird Shrine, there are many whose spiritual creatures are stuck at the peak of the second level of mythology.

If the Li family cannot get the rule crystal from Lin Yuan this time, then they will never have the chance to get the rule crystal from Lin Yuan again.

When Lin Yuan turned to the unique resources of the Liyun Bird Shrine, he discovered that the unique resources referred to by the Grand Elder of the Liyun Bird Shrine were all some cool flying spiritual creatures that were unique to the Liyun Bird Shrine after special cultivation.

If it were in the past, Lin Yuan might have decided to exchange them.

But now Lin Yuan has Xiao Hei as a flying spirit creature. After Xiao Hei was promoted to a gold-level fantasy species, his speed is not much weaker than that of a platinum-level divine black swallow.

Enough to meet Lin Yuan's requirements.

On the other hand, Lin Yuan wanted to build a spirit vehicle, so he didn’t need just one or two cool flying spirits.

But if Lin Yuan was asked to take out nine or twelve rule crystals to exchange for nine or twelve cool flying spirit creatures, Lin Yuan felt that there was no need for that.

He possessed pure spiritual energy that even a five-star creator could not mix, so it was not difficult for him to cultivate a new type of flying spiritual creature.

Moreover, the flying creatures induced to mutate by using pure spiritual energy will only be better than the ones cultivated in Li Yun's bird shrine.

Just when Lin Yuan was thinking that if there was really no other choice, he would ask the Li family to exchange a large amount of rule crystal fragments.

Lin Yuan's gaze stopped directly on the last page of the album.

There is no wrong version in the 1619 book forum!

When Lin Yuan saw the last page of the album, his heart skipped a beat.

If I could exchange this thing from the Liyun Bird Shrine, then my previous idea would be able to go from fantasy to reality.

It can also be said that it is equivalent to saving oneself decades of hard work.

Lin Yuan pointed to an ordinary green grass with serrated leaves in the atlas and asked the chief elder of the Liyun Bird Shrine.

"Is the seed strain of the Heaven and Earth Spiritual Thing Muscle Super Memory Grass marked in this atlas cultivated from the mother strain of the Heaven and Earth Spiritual Thing Muscle Super Memory Grass?"

“How effective are the daughter plants compared to the mother plants?”

"I see that there are five strains marked on the atlas of your Liyun bird niche. I wonder how you, the Li family, usually use the strains of this super memory grass?"

The great elder Li Yunniaokan was stunned by Lin Yuan's three consecutive questions.

When Lin Yuan turned to the last page, the heart of Great Elder Li Yunniaokan fell to the bottom and he almost despaired.

But I didn't expect that Lin Yuan would be interested in this super memory grass.

However, Great Elder Li Yunniaokan was somewhat confused about what Lin Yuan meant.

I don’t know if Lin Yuan was just asking casually or if he wanted to use the rule crystal to exchange for the super memory grass seeds.

If this is true, then Li Yun Bird Shrine would have picked up a huge bargain.

Although the Body Super Memory Grass is the basis for cultivating flying spirit creatures in the Liyun Bird Shrine, it allows flying spirit creatures to remember their routes.

However, the Wuzhu Muscle Super Memory Grass in the Li family treasury are all divisions of the mother plant. Although they have the same effects as the mother plant, they do not have the ability to divide from the mother plant.

Therefore, trading the Muscle Super Memory Grass to Lin Yuanli Yunniao Kan is essentially equivalent to getting two Rule Crystals for free.

The chief elder of the Liyun Niaokan cleared his throat and explained to Lin Yuan without hiding anything.

"The seeds of the super memory grass are usually planted in a closed space. The super memory grass will emit a special fragrance."

"The muscles of creatures that smell this fragrance will enter a super memory mode, able to memorize complex movements and routes."

First update.
