National Cave: I created the supreme fairyland

Chapter 730 Comprehensive upgrade
"Yes!" Hearing the prompt message in his mind, Fang Yu chose "Yes" without any hesitation.

As soon as he finished speaking, all the dragon veins and spirit veins floating in the sky flew into the ground.

When Fang Yu saw this, he thought about it and all the 5200 spirit veins that had flown underground were transferred away by him.

He placed 1500 of them underground in Seoul and Jiuzhou City respectively, and the remaining 2200 were placed in the wild of Hongmeng Fairyland.

The reason why the spiritual veins are placed in the wild is because the two palace-type cave spiritual treasures, Hancheng and Jiuzhoucheng, have the function of locking spirits (the spirit here refers to the spiritual energy of heaven and earth).

Of course, Hongmeng Dao Palace also has the function of locking souls.

If all these 5200 spiritual veins were placed under Seoul, the spiritual energy of heaven and earth would be blocked within the city by Seoul and Kyushu City and would not be able to dissipate.

If the spiritual energy of heaven and earth in the wild is thin, and the spiritual medicines planted in the wild, or the exotic beasts raised in the wild do not have enough spiritual energy of heaven and earth, the medicinal properties of the medicinal materials and the growth rate of the exotic beasts will definitely be affected, which is not conducive to the development of Hongmeng Fairyland.

Therefore, in order not to affect the development of the Hongmeng Fairyland, Fang Yu will not place all the spiritual veins under the ground of cities where people gather.

After calming himself down, Fang Yu immediately summoned the [Dongtian] attribute panel.

The next moment, a virtual light screen like a menu appeared out of thin air in front of Fang Yu.

[Dongtian]: Hongmeng Fairyland.

【Level】: Eighth Grade.

【Area】: 30 billion square kilometers.

[Buildings]: Hongmeng Tree (quality unknown, unknown reason, tentatively rated ninth grade, cannot be upgraded), Hongmeng Holy Spring (quality unknown, seventh grade), Hongmeng Dao Palace (myth, seventh grade [0/1000 trillion]), Dragon Vein x1500 (Legend, first grade) [+], Spirit Vein x5200 (rare, first grade) [+]...

[Attribute]: Chaos (myth).

Seeing the plus signs behind the 1500 new dragon veins and 5200 new spirit veins in the [Buildings] column, Fang Yu knew that the function of the Hongmeng Tree could be used again.

Fang Yu did not hesitate at all and clicked on the two plus signs on Dragon Vein x1500 [+] and Spirit Vein x5200 [+].

The next moment, the familiar bright purple divine light arrived as promised, covering the 1500 dragon veins and 5200 spiritual veins that had just been bound to the Hongmeng Fairyland.

After a few breaths, the divine light dissipated.

Fang Yu suddenly discovered that the 1500 dragon veins that had just been bound to the Hongmeng Fairyland had all transformed into innate ancestral veins of mythical quality, and the 5200 rare quality spirit veins had all transformed into dragon veins of legendary quality.

Fang Yu was not surprised by this, because he was already accustomed to similar situations.

After calming himself down, Fang Yu immediately checked his own Cave Heaven Divine Stone reserves, which amounted to more than 1200 trillion pieces.

Fang Yu was a little surprised to see that his cave heaven divine stone reserves were more than 1200 trillion.

He had not checked the reserves of the cave's divine stones for some time, but he did not expect that he had accumulated such a staggering wealth without realizing it.

The innate ancestral vein of mythical quality: 10 Cave Heaven Divine Stones are needed to upgrade from the first grade to the second grade, 100 million Cave Heaven Divine Stones are needed to upgrade from the second grade to the third grade... and so on. After that, the number of Cave Heaven Divine Stones required for each subsequent upgrade is ten times that of the previous grade.

The level of Fang Yu's Hongmeng Fairyland is now eighth grade. As long as he has enough Dongtian Magic Stones, he can now upgrade the levels of all Dongtian Magic Treasures bound to the Hongmeng Fairyland to eighth grade.

Of course, the Hongmeng Tree is an exception, because the Hongmeng Tree cannot be upgraded with the Dongtian Divine Stone.

Although the cave-sky spiritual treasures bound to the Hongmeng Fairyland can be upgraded to the eighth grade, Fang Yu did not upgrade the other cave-sky spiritual treasures that can be upgraded except for the Zhuxian Demon Soldier Tower.

It’s not that he doesn’t have enough Cave Heaven Divine Stones, but that he himself doesn’t want to upgrade.

To upgrade an innate ancestral vein from the first grade to the eighth grade, it would cost 1111.111 billion cave heavenly divine stones. If all 1500 mythical first grade innate ancestral veins were upgraded to the eighth grade, it would cost 1666666.5 trillion cave heavenly divine stones.

Without any hesitation, Fang Yu immediately spent 1666666.5 billion Cave Heaven Divine Stones to upgrade all 1500 first-grade innate ancestral veins to the eighth grade.

The next moment, Fang Yu immediately felt the vast innate spiritual energy surging out from the ground under the Hongmeng Tree.

Fang Yu ignored all this, and then spent another 20 trillion Cave Heaven Divine Stones to upgrade all the previous 200 seventh-grade innate ancestral veins to the eighth grade. The upgrade of the seventh-grade innate ancestral vein to the eighth grade cost 1000 billion Cave Heaven Divine Stones for each vein.

After Fang Yu upgraded all the innate ancestral veins under the Hongmeng Taoist Palace to the eighth level, he looked at the 5200 legendary quality, first-level dragon veins that had just been bound to the [Architecture] column of the cave attribute panel.

Legendary quality dragon veins: Upgrading from the first grade to the second grade requires 1 Cave Heaven Divine Stones, and upgrading from the second grade to the third grade requires 10 Cave Heaven Divine Stones, and so on. For each subsequent upgrade, the number of Cave Heaven Divine Stones required is ten times that of the previous grade.

In other words, it would cost 111.1111 billion cave heavenly divine stones to upgrade each legendary first-grade dragon vein to the eighth-grade level.

If all 5200 legendary first-grade dragon veins were upgraded to the eighth-grade level, a total of 577777.72 billion would be required.

Without any hesitation, Fang Yu immediately spent 577777.72 billion Dongtian Divine Stones to upgrade all 5200 legendary first-grade dragon veins to the eighth grade.

Fang Yu had just upgraded the dragon vein when the people of Seoul and Jiuzhou City immediately felt that the spiritual energy in the air had increased a lot. They were not surprised.

Because they knew that the increase in the spiritual energy of heaven and earth was the work of their Holy Emperor.

Under the Hongmeng Tree, Fang Yu had just finished upgrading 5200 dragon veins, and then spent 3 trillion Cave Heaven Divine Stones to upgrade all 300 previously bound legendary seventh-grade dragon veins to eighth-grade, spending 100 billion Cave Heaven Divine Stones every day.

After that, Fang Yu upgraded all fourteen mythical seventh-grade cave treasures to the eighth grade, including [Hongmeng Taoist Palace], [Three Lights Divine Spring], [Demon-Slaying Taoist Tower], [Yin Yang Divine Spring], [Tian Danfang], [Divine Weapon Forging Workshop], [Jiu Tian Xi Ran], [Ren Shui Pan Tao], [Tower of Time], [Holy Spring of Creation], [Holy Spring of Life], [Martial Arts Field of the Heavens], [Garden of All Beasts of the Heavens], and [Underworld].

A total of 14000 trillion Dongtian divine stones were spent, with each piece costing 1000 billion.

Then he spent another 100 trillion cave heaven divine stones to upgrade the Hongmeng Holy Spring from the seventh grade to the eighth grade.

It is worth mentioning that after the cave treasure is upgraded, its efficacy will naturally be enhanced.

For example, the [Three Lights Divine Spring], the seventh-grade Three Lights Divine Spring can only revive cultivators at the Dharma Realm and below, but the eighth-grade can revive cultivators at the Return to Oneness Realm and below.

Not only that, the inventory and recovery speed of the eighth-grade Sanguan Divine Spring have also increased. The previous inventory was 70 tons, and now it has become 80 tons, and the recovery speed has increased from 7 tons/day to 8 tons/day.

Another example is the [Divine Weapon Forge]. A seventh-grade Divine Weapon Forge can forge low-grade spiritual weapons in batches as long as blueprints are added, while an eighth-grade Divine Weapon Forge can forge mid-grade and high-grade spiritual weapons.

Of course, the corresponding blueprints must be available before the Divine Weapon Forge can forge weapons in batches.

Fang Yu just took a quick look at the properties of the upgraded cave treasure and ignored it.

He checked and found that he still had more than 900 trillion Cave Heaven Divine Stones on him. He immediately upgraded all the remaining Cave Heaven Magic Treasures that had not yet been upgraded to the eighth level to the eighth level, spending almost 40 trillion.

The reason why it costs so much is that there are 365 mythical quality stars in his Hongmeng Fairyland. It takes 1000 billion Cave Heaven Divine Stones to upgrade each star from the seventh grade to the eighth grade, and 365 stars will cost 365000 trillion.

After taking a look, there were still more than 900 billion Cave Heaven Divine Stones left, so Fang Yu did not move.

The level of Fang Yu's Hongmeng Fairyland is eighth grade. The eighth grade cave heaven can be bound to twenty-four cave heaven spiritual treasures (except for cave heaven spiritual treasures that are not restricted).

In addition to the unrestricted cave-heaven spiritual treasures, Fang Yu has now bound a total of twenty-one cave-heaven spiritual treasures. As long as he binds three more restricted cave-heaven spiritual treasures and upgrades their levels to the eighth grade, he can raise the level of the Hongmeng Fairyland again.

However, Fang Yu hasn't figured out what to bind yet.
