Yu Qin was just an ordinary female foundation-building cultivator. Lu Changan didn't pay much attention to it and planned to remind Young Master Xia another day.

During this trip, he left the Earth Rock Rat on Qiufeng Island and headed to Yunyan Fairy City alone.

A few days later.

Yunyan Fairy City, Wanshu Pavilion.

A young man with a yellow beard walked out of the pavilion holding a jade tube in his hand, and his figure quickly merged into the crowd of people in the fairy city.

Wanshu Pavilion is the largest bookstore chain in the Jingguo Merchant Alliance. In addition to selling mainstream martial arts and secret techniques, knowledge on cultivating immortals and hundreds of arts, it also sells some fragments of ancient books.

""The Record of Innate Dao Body", priced at 1,800 spirit stones, records most of the innate Dao bodies that have appeared in Daqing's cultivation world for tens of thousands of years..."

After a while, Lu Changan disguised himself as a young man with a yellow beard and entered an ordinary inn in the city.

In the guest room, his consciousness entered the jade tube and examined it.

There are many fields in the world of immortality, and the knowledge is vast.

Even if the consciousness of the Danjie cultivator is exploded, the limit of knowledge that his memory can carry may be just a drop in the ocean for the vast world of immortality that has gone through endless years.

Therefore, even if Lu Changan rebuilds his core formation at its peak, it is impossible to cover everything in terms of information.

For example, the Five Elements of Earth, the Xuantian Gourd, the Innate Treasure Body... Lu Changan may be missing some information, or his understanding may not be comprehensive enough.

"Found, the 'Hanso Chalcedony' innate Taoist body!"

Not long after, Lu Changan found information about Xia Wenyue's Taoism in the jade tube.

According to the records of "Xiantian Dao Ti Lu", Hanpo Chalcedony Dao Physique once appeared in the Daqing cultivation world, but compared to other mainstream Dao Physiques, it is relatively unpopular.

The descriptions in it are much more detailed than the few words that Lu Changan accidentally learned from ancient books in his previous life.

"Xia Wenyue's innate Taoist body is indeed altruistic."

After reading the records in the jade tube, Lu Changan was surprised and pleasantly surprised.

"only……"

Then, he showed a confused look.

The benefits of cold chalcedony exceeded Lu Changan's expectations, and it has more than one use.

One of its uses is similar to what Lu Changan speculated.

For Taoist owners of Cold Chalcedony who have cultivated to the foundation-building stage or above, their jade bones contain the "Cold Chalcedony" that has been cultivated for many years, which can help break through bottlenecks and realms.

The higher the level of cultivation, the better the effect of breaking through bottlenecks.

At the early stage of foundation building, "Cold Chalcedony" almost ignores the small realm bottlenecks during the foundation building period. Its effect is far better than the level-breaking elixir, and it will not affect the monk's potential.

At the later stage of foundation building, "Cold Chalcedony" can slightly increase the chance of forming an elixir and slightly improve the quality of the elixir.

"It is equivalent to an enhanced version of the Crystal Condensation Pill, and is close to the effect of a high-quality Crystal Condensation Pill."

If Lu Changan says he is not moved, he is deceiving himself.

However, this kind of effect can only be achieved after Xia Wenyue reaches the later stage of foundation building.

Moreover, extracting cold chalcedony will cause permanent potential damage to the innate Tao body, which is tantamount to killing the goose to obtain the egg, benefiting oneself at the expense of others.

"The altruistic nature of Hanpo Chalcedony, in the foundation building stage, is far from maximizing benefits..."

Lu Changan's eyes flickered and he murmured.

This brings us to the second use of the cold chalcedony body.

If Xia Wenyue reaches the mid-to-late stage of pill formation and can still retain the virgin Yuan Yin, she will be able to penetrate the cold soul and chalcedony, and hopefully breed the only "Taiyin Jade Liquid" in her body.

"Taiyin jade liquid can slightly increase the success rate of promotion to the Nascent Soul stage!"

Lu Changan couldn't help but breathe heavier.

If we say that the "cold chalcedony" in the foundation building stage can be taken by outsiders by force.

Then the "Taiyin Jade Liquid" in the elixir formation stage must be given to the male cultivator through dual cultivation by the female cultivator who owns the Tao body, willingly and actively cooperates.

Cannot be forced to obtain.

Giving Taiyin jade liquid will not affect the potential of Taoists.

Therefore, those who are in the cold chalcedony body before the elixir formation stage is the most dangerous stage.

After reaching the elixir formation stage, the risk is greatly reduced, and it becomes a favorite among male cultivators who seek to please.

As for the third use.

This is a common feature of most Yin treasure bodies, and can be used as an excellent dual cultivation or furnace object.

Compared with the first two uses, the third one is not so eye-catching, it can only be said to be the icing on the cake.

To Lu Changan, it was even useless.

His evergreen practice is limited by time.

External forces such as pills can only speed up the daily practice efficiency, but cannot change the overall practice progress.

If Xia Wenyue breaks through that relationship when her cultivation is insufficient, she will lose the great opportunity of "Taiyin Jade Liquid".

…

"Slightly increasing the chance of being promoted to Nascent Soul, although it is not as good as the Infant Transformation Pill, but even if it can only add a little effect, it will make many true elixir majors flock to it..."

Lu Changan took a deep breath to calm down his excited mood.

"However, it is not as easy as imagined to obtain the 'Taiyin Jade Liquid' smoothly."

Lu Changan understood the difficulty.

Even with the earth spirit root talent, it often takes more than a hundred years to reach the mid-to-late stage of pill formation.

What's more, Xia Wenyue's early practice was delayed for some years.

"Over the past one hundred years, there have been many changes, and there have been too many changes!"

"Not only do we have to ensure that she has cultivated to the mid-to-late stage of pill formation, but she also has to be pure of heart and keep her body as pure as jade."

This is the reason why Lu Changan is confused.

Among the conditions to be met, it is relatively difficult for Xia Wenyue to cultivate to the elixir-forming stage.

Innate treasure body, as long as you find the right method, the speed of cultivation is often the same as the earth spirit root.

The changes of more than a hundred years and the suppression of human desires may be a bigger problem.

Take Lu Changan as an example. Among monks, he is considered to be pure-minded and celibate.

He is now over 150 years old, and has only experienced a few relationships or romantic relationships, with an average of only once every few decades.

It is used to relieve the physical and psychological depression caused by the boring years of practice.

It won’t turn into an emotionless cultivation machine.

"In such a long period of time, not only are there many external variables, but the human heart is also the biggest variable..."

Lu Changan knew that even though Xia Wenyue admired and admired him now, and was gentle and considerate, it would be hard to tell after hundreds of years.

The potential and advancement speed of the innate Tao body are difficult to predict.

Lu Changan's cultivation speed is so slow, he might catch up or even overtake him in a hundred years.

"As for Xia Wenyue, we need to consider this in the long term."

Lu Changan thought for a long time and had a rough idea in his mind.

…

Three days later.

Lu Changan changed his identity through the Baihuan Mask, and sold two inferior Foundation Building Pills in a large store in Yunyan Fairy City.

From the two foundation-building pill materials in previous years, Lu Changan refined a total of one genuine product and three inferior ones.

Originally, Lu Changan planned to sell all three inferior products, leaving only one genuine one.

Now there is an extra bad one, prepared for Xia Wenyue.

"With the innate Taoist body, the cultivation qualifications are at least as good as the earthly spiritual roots, so there is no need to prepare such good breakthrough resources."

Lu Changan thought so.

In the next few days, Lu Changan changed his identity again and bought some materials for quasi-third-level puppets to improve his puppet skills and increase the error tolerance rate in frontal combat.

After completing the purchase, Lu Changan went to the Snow Fox Chamber of Commerce to visit Master Hanyu in the identity of the old man in coir raincoat, "Zhenren Xiang".

A few years ago, the third-level beast pills that Lu Changan purchased from the Snow Fox Chamber of Commerce had been consumed by the Earth Rock Rats.

As a third-level great demon, Earth Rock Rat's training environment on Qiufeng Island is actually a bit condescending.

Therefore, Lu Changan must ensure adequate supply in terms of animal pills.

Over the years, the Earth Rock Rat's cultivation speed has been faster than Lu Changan expected.

Perhaps due to the formation of the "Half-Step Golden Pill", the Earth Rock Rat's cultivation speed in a less than ideal aura environment is actually faster than that of most high-grade bloodline monsters, directly catching up with the earth-grade bloodline.
