Longevity: Never leave the mountain until you are invincible

Qingzhou and Canglanhai are located in a corner of Tianhuang Continent. Since the great war tens of thousands of years ago, the spiritual energy has gradually declined and entered an era similar to the end of the law.

The large spiritual veins have dried up one after another, causing the resources of the Qingzhou and Canglanhai cultivation worlds to become increasingly barren, unable to support the birth of Jindan Zhenjun.

It is no longer as prosperous as it used to be.

Even the top forces such as Tianyou Palace, which once gave birth to Yuanying Tianjun and had Jindan Zhenjun sitting in charge, can only flee Qingzhou and go to the inland of Tianhuang Continent.

Without the existence of large spiritual veins, there is naturally no place suitable for planting Xuanpo trees.

"If other people get the Xuanpo tree seeds and want to plant Xuanpo trees, they can only leave Qingzhou and go to the inland of Tianhuang Continent to find large spiritual veins, but I am different."

Chu Chen smiled faintly. He has a Jianmu seedling.

When the Jianmu seedling grows to a certain extent, it can open up a secret space. He can plant the Xuanpo tree in this secret space and carry it with him.

Not only is there no risk of exposure, but the Xuanpo tree can also be better cultivated.

Jianmu is the mother tree of all trees and one of the most supreme spiritual plants in the world. If the Xuanpo tree can often contact Jianmu and be infected with the breath of Jianmu, it may not be impossible to transform into a higher-grade spiritual plant.

"The Xuanpo tree is originally a fourth-grade spiritual plant. With the influence of Jianmu, it is very likely to transform into a fifth-grade spiritual plant, or even a top spiritual plant above the fifth grade."

Chu Chen's eyes lit up, and he felt that this matter had great potential.

The fruit produced by the Xuanpo tree can nourish the soul of the cultivator and enhance the power of the divine mind.

If it transforms into a spiritual plant above the fifth grade, he will not have to worry about the lack of spiritual medicine to enhance the power of the divine mind for a long time in the future.

"It's too early to say this now."

Chu Chen shook his head gently. The Jianmu seedlings are still immature and have not reached the level of opening up the secret space.

Every twenty years, the Jianmu seedlings can receive a ray of purple Xuan spiritual energy for their own growth. Now it is less than seventeen years away from the next time the Jianmu seedlings receive purple Xuan spiritual energy.

But a wisp of purple mysterious spiritual energy may not be enough to make the Jianmu seedling grow to the point of opening up the secret space, but Chu Chen is not in a hurry.

One wisp of purple mysterious spiritual energy is not enough, just a few more wisp of purple mysterious spiritual energy will do.

With the immortal fruit, Chu Chen has patience and time.

"Study this Xuanpo tree first."

Chu Chen looked at the Xuanpo tree in his hand, and he had many questions in his mind.

The Xuanpo tree can mature as long as it devours a large amount of spiritual energy, or devours its own kind.

Before the Xuanpo tree metamorphosis, it existed for at least a thousand years in the form of a sacred heart relic. As a sacred object of the Wusheng Sect, it was supported by the Wusheng Sect for hundreds of years.

Later, it fell into his hands and was used to assist in practicing the Soul-stealing Body-forging Sutra.

These two stages were injected with a large amount of warrior true qi and heaven and earth spiritual energy, but the Xuanpo tree failed to mature.

Why is this?

"The Xuanpo tree species also have different grades. They are divided into upper, middle and lower grades based on the yellow substance in the Xuanpo tree species, or more precisely, the spiritual seed power.

The more spiritual seed power there is, the more active it is, and the higher the grade of the Xuanpo tree species."

Chu Chen flipped through the information sent by Jianmu, and a flash of understanding flashed in his eyes.

Only the upper-grade Xuanpo tree species are qualified to absorb spiritual energy, promote their own maturity, and grow into a Xuanpo tree.

No matter how much spiritual energy the middle-grade and lower-grade Xuanpo tree species absorb, they will never mature.

For example, the 'Sacred Heart Relic' obtained from the casual cultivator is a lower-grade Xuanpo tree species, and the spiritual seed power is solidified and has no activity, which is equivalent to two dead seeds.

It cannot absorb and store spiritual energy, and can only be used to refine second-grade elixirs at most.

The spiritual seed power contained in the Sacred Heart Relic is not much, and it can barely be considered a middle-grade Xuanpo tree species.

Therefore, the Sacred Heart Relic can absorb and store spiritual energy, but cannot absorb spiritual energy to mature itself.

After devouring two 'Sacred Heart Relics', the Sacred Heart Relics transformed into a top-grade Xuan Po Tree, which has the ability to absorb the spiritual energy of heaven and earth, mature itself, and grow into a Xuan Po Tree.

This process can be shortened by letting the Xuan Po Tree devour other tree species.

Of course.

Chu Chen was lucky enough to get three Xuan Po Trees. It would be like looking for a needle in a haystack to find another Xuan Po Tree in Qingzhou and Canglan Sea.

Whether there are any Xuan Po Trees in Qingzhou and Canglan Sea is a question mark.

Moreover, the Xuan Po Tree in Chu Chen's hand is already a top-grade Xuan Po Tree. Even if it is left alone, it can slowly mature and reach the standard for planting.

"The Jianmu seedling has not yet opened up the secret space, so there is no need to rush to plant the Xuan Po Tree. However, the spiritual patterns on the Xuan Po Tree can be studied."

The Xuan Po Tree grows natural spiritual patterns, which are interwoven into a complex spiritual pattern structure.

At the first sight of the spiritual pattern structure on the Xuanpo tree, Chu Chen realized that this spiritual pattern structure was very useful.

The spiritual pattern structure on the Xuanpo tree is similar to the natural formation under the Shuangyue Lake.

That is, the Nine Palaces Wanhua Formation.

Unlike the Nine Palaces Wanhua Formation, the spiritual pattern structure on the Xuanpo tree can not only be used to arrange the formation, but also to refine magic tools and draw talismans.

"The Xuanpo tree is a spiritual plant in the aspect of the soul. The spiritual pattern structure on the Xuanpo tree also involves the soul level. If it is used to draw talismans, it is likely to draw soul attack talismans or soul defense talismans.

If it is used to arrange a large formation, it can construct a soul formation."

Chu Chen's eyes flickered.

The original formations, talismans, magic tools, etc. in the world of cultivation are all the products of the cultivators' comprehension of the natural spiritual patterns existing between heaven and earth and their research.

He can also study the spiritual pattern structure on the Xuanpo tree and transform it into talismans or formation patterns.

As for converting it into a magical instrument restriction, Chu Chen gave up this plan.

After all, if you want to convert the spiritual pattern structure on the Xuanpo tree species into the runes for drawing talismans, or the magical instrument restrictions for refining magical instruments, it will take a lot of energy to study.

There are methods for refining spiritual instruments in the Tiangong Zhenjie, and there are quite a few of them. He doesn't need to waste his energy on this.

"However, the study of spiritual patterns should be put after cultivating Taixuan Guizhen Gong and breaking through the Jindan stage."

Chu Chen flipped his hand and put the Xuanpo tree species into the storage ring.

The Xuanpo tree species is very special. Although it has been revived, it can be directly stored in the storage ring like an ordinary dead object, without having to be stored in a spiritual medicine crystal box first and then put into the storage ring.

"It's time to attend the opening ceremony of Tiantong Jinzhuang."

Then, Chu Chen left the cave and came to a three-story building in the southeast corner of Dazefang City.

The small building is simple and elegant, with a plaque with the words "Tiantong Jinzhuang" hanging high.

At this moment, people were coming and going in Tiantong Jinzhuang.

Many cultivators came to give gifts. Tiantong Jinzhuang was a big force from Qingzhou, making a living by selling intelligence. Most cultivators in Canglanhai were willing to make friends with it.

Chu Chen did not reveal his identity. He disguised himself as a ninth-level Qi training cultivator, sent gifts, and sneaked into Tiantong Jinzhuang.

As soon as he entered Tiantong Jinzhuang, he saw Jin Kexing talking with many foundation-building cultivators.

Chu Chen did not disturb Jin Kexing. If he showed up to meet Jin Kexing, he would have to deal with a group of foundation-building cultivators. There was no need for this.

He just secretly sent a message to Jin Kexing: "After the opening ceremony is over, I will meet you again."
