The great elder of Liyunniaokan and Long Tu were both thinking about the crystallization of the trading rules.

After the two exchanged glances, the great elder of the Li Yunniaokan began to speak to Lin Yuan in a somewhat flattering tone.

"Sir, I wonder if you can give us a few of the rule crystals for the Liyun bird niche?"

"We, the Liyun Niaoku, are willing to open our treasure house for you to choose from."

The words of the great elder Li Yunniaokan made Lin Yuan and Long Tu stunned at the same time.

Long Tu didn't expect that the great elder of Li Yunniao Kan would be willing to spend such a huge amount of money.

Opening the treasury is equivalent to revealing all the precious resources of the Li family to Lin Yuan.

The treasure house of a top force often hides the secrets of that top force. For the sake of the crystallization of the rules, the old man, the eldest elder of the Li family, has made the Li family's secret choice public in front of Lin Yuan.

This amount of investment is not small.

For a moment, Long Tu didn't know whether he should keep up with the pace of the great elder Li Yunniaokan.

Li Yunniao Kan has been a top force for more than 40 years. There may not be any precious secrets in the treasure house with a shallow foundation, but it is different for its own treasure house.

A hundred years before this spiritual energy revival, there was a spiritual energy vacuum period of nearly five years.

Before the five-year spiritual energy vacuum period, there was a period of thin spiritual energy that lasted for nearly five thousand years.

It was this hundred years of spiritual energy revival that allowed humans to contract spiritual creatures and have spiritual professionals.

However, the ancestors of the Long family had already collected many treasures by taking advantage of the changes in spiritual energy before the spiritual vacuum period, when the spiritual energy was thin, laying the foundation for the rise of Panlong Valley.

It would be extremely painful if even one of these things was chosen.

Therefore, Long Tu planned to wait and see.

If Lin Yuan agrees to trade with the Li Yun Bird Shrine, then see what Lin Yuan can pick out from the treasure house of the Li Yun Bird Shrine and then decide whether to follow through.

Even though Long Tu had obtained a rule source crystal, allowing his damaged spiritual creature to pass the threshold of the third realm of mythology.

However, no force would have too many rule crystals.

Moreover, the current Long family also has a huge demand for rule crystals.

It can be said that almost the vast majority of the peak emperor-level powerhouses have the capital to become emperor-level powerhouses, but they are stuck at the peak of the emperor-level and cannot make any progress because they do not have the crystallization of rules.

Lin Yuan did not expect that the Great Elder of the Li Family would actually open the treasure house of the Li Yun Bird Shrine to him. The Great Elder of the Li Family's actions directly made Lin Yuan's heart move.

But even so, Lin Yuan still doesn't plan to lose too many rule crystals.

Lin Yuan waved his hand, and three crystal fragments as crystal as diamonds appeared in his hand.

After Lin Yuan tossed the crystal fragments twice, he spoke to the chief elder of the Liyun Bird Shrine.

"I only have three rule crystal fragments here at the moment."

"Since the Li family is so sincere, I am willing to take out two of them and make a deal with them."

Lin Yuan's words made Long Tu, who was originally prepared to watch the fun, unable to remain calm any longer.

However, even as the current head of the Long family, Long Tu, the helmsman of the Long family, could not make a decision on something like making the treasure house of Panlong Valley public.

Lin Yuan took out three rule crystals but only traded two with Li Yunniao Kan.

That means it is possible to trade for the remaining rule crystal.

Long Tu took a deep breath and said in a deep voice.

Long Tu had thought carefully before saying this.

To be honest, the improvement a poisonous spirit creature gets from absorbing the rule crystal of the third level of poisonous mythology is far greater than that from absorbing the rule crystal the size of a fingernail.

However, the poison rules are too niche, and the huge Panlong Valley has no demand for them.

Moreover, even if the benefits of the Rule Crystal of the Third Level of Poison Mythology to poison-type spiritual creatures are more than fifty times that of the Rule Crystal the size of a fingernail, it still cannot help a spiritual creature stuck at the peak of the Second Level of Mythology to advance to the Third Level of Mythology.

It is completely possible to exchange a mythical third-level poison rule crystal that has been gathering dust in the warehouse and is of no use to the Long family for a living lord-level mythical third-level spiritual creature.

But this is already the limit of what Long Tu can give.

Lin Yuan was suddenly delighted when he heard this.

However, just as this joy began to spread outward from Lin Yuan's heart, it was forcibly suppressed by Lin Yuan.

Not a trace of it leaked onto his face.

There is no wrong version in the 1619 book forum!

This ability to not show one's emotions on one's face is also the result of Lin Yuan's improvement in his state of mind over the past eight months.

The poison rule is a very niche existence among the rules. So far, the princess's skirt has absorbed a lot of rule crystal fragments but has not absorbed even a trace of the poison rule.

The scarcity of poisonous spiritual creatures in the Huiyao Federation makes the position of poisonous rule crystals very awkward among rule crystals.

However, in Lin Yuan's opinion, the poison rules can be of great use to him.

The will and rules on the princess's skirt can be bestowed upon Lin Yuan. During the previous battle with Zhou Luo, Lin Yuan accidentally discovered that the rules engraved in the princess's skirt can enhance his immunity to the attributes of the engraved rules.

As a spiritual professional with a fragile body, what he fears most in battle is often not the damage from the physical and elemental levels, but the poison.

Even if the spiritual creature Lily in Lin Yuan's hand can regenerate severed limbs and repair the genetic template, it still cannot eliminate the fierce and stubborn toxicity.

If Lin Yuan's body was attacked by a poisonous spirit creature in a life-and-death battle, then Lin Yuan could only quickly remove the injured part.

Then, through the unique characteristics of Lily Lily, the cut part will be regrown intermittently.

At best, Lin Yuan's approach can only be used to deal with spiritual creatures whose toxins spread slowly.

Lin Yuan's ethereal jellyfish skill space transfer transfers elemental energy, and the poison system is not pure elemental energy.

Therefore, the defensive effect of spatial transfer against toxins is not strong.

Lin Yuan has never had any good countermeasures to improve his resistance to toxins.

Although some spiritual materials can increase the resistance of spiritual professionals to toxins, these spiritual materials that enhance the resistance of spiritual professionals to toxins are often highly toxic themselves.

While improving the body's ability to resist toxins, it will also be corroded by the toxins, causing great pain, and may even cause skin ulcers and disfigurement.

Although Lin Yuan does not care much about his appearance, disfiguring himself in order to improve his resistance to toxins is obviously not what Lin Yuan wants.

Lin Yuan couldn't help but think in his heart.

“Now if I can exchange a rule crystal for a Lord-class Mythology Level 3 poison rule crystal, after Princess Luoqun absorbs the Mythology Level 3 poison rule, my own resistance to toxins will be able to achieve a qualitative leap.”

"This kind of improvement is simply incomparable to those anti-poison spiritual materials."
