Longevity through Upgrading Buildings-Chapter 500 - 237: Demon Dao Invasion!

After looking around here, Ji Yuan naturally came to the side of the [Fish Pond] to check on the second Frost Serpent.

As a result, he found that the Frost Serpent, which was still in the early stage of Tier One a few days ago, had now reached the middle stage of Tier One.

He observed it for a while and then understood the cause.

Most likely, the other Frost Serpent shared a small piece with it when it was eating a Tier Two Spirit Fish, allowing its strength to break through.

However, these two Frost Serpents need to be given names, otherwise it will be hard to tell them apart.

Ji Yuan didn’t spend much effort on such matters and directly named the larger one "Monday" and the smaller Frost Serpent "Tuesday."

If another one comes, it will be "Wednesday!"

Everything on Mist Island was well, and with Tu Yue present, all the structures were operating in an orderly manner, so Ji Yuan could return to [Spirit Vein] to cultivate with peace of mind.

Ji Yuan’s current cultivation just reached the late stage of Foundation Establishment. To continue improving, he needed to comprehend the "Sword Manual" and strive to condense the sword embryo for the sixth Lifebound Flying Sword.

Yet, the further he delved into the "Sword Manual," the more difficult it became to comprehend.

But fortunately, Ji Yuan had some assistance from the [Enlightenment Room], so the difficulty wasn’t too bad, it just required more painstaking effort.

It was challenging to improve cultivation, so Ji Yuan planned to completely refine the incomplete magical treasure, the Celestial Poison Needle, given by Senior Brother Ren Kui. By that time, even if he reached the peak of Foundation Establishment, this Celestial Poison Needle would be a major trump card.

Furthermore, it was unknown what kind of poisonous materials were used during its refinement, as it possessed an extremely domineering toxicity. Although not instantly fatal, if struck by it, one would practically be rendered useless for a lifetime.

When Ji Yuan initially received it, he only lightly refined it and didn’t have time to become familiar with it.

Now it was fine, staying inside the [Spirit Vein] with an endless supply of Spiritual Qi replenishment.

At night.

Ji Yuan summoned the Celestial Poison Needle, letting it hover in front of him. With both hands he formed a hand seal, Spiritual Qi sprang from the seal, continuously refining this magical treasure.

The process was generally tedious, merely a matter of nurturing every part of the magical treasure with his own Spiritual Qi until it was nurtured to the extreme, achieving complete control over it as if it were an extension of his own body.

Moreover, the deeper the refinement, the smaller the energy consumption during activation.

After the refinement was completed, Ji Yuan ascended to the highest point of Mist Island, attempting to integrate with it at the mountain peak.

During this time, he also tried using the sword embryos of the five Canglan Flying Swords to construct a Canglan Sword Array.

Unfortunately, the results were unsatisfactory. If it was used for regular detainment... detaining cultivators weaker than him, it wasn’t useful, and for those on his level, the sword array did not have much effect.

It was ultimately because there were too few sword embryos. If the number of sword embryos could reach seven, perhaps it could be used against enemies.

The power would likely be very strong.

For now, though, it could only be used individually against enemies.

Even when used individually, even with Ji Yuan’s Divine Soul, controlling five Flying Swords simultaneously against an enemy would require meticulous practice.

If replaced with another Foundation Establishment Cultivator, being able to simultaneously control two Flying Swords would already mean having an exceptionally strong Divine Soul.

Just like when Ji Yuan previously engaged in magical combat with Jiang Hong, did Jiang Hong lack spiritual artifacts and magical treasures?

But why was he always able to only use one or two at a time?

It was all because the strength of the Divine Soul wasn’t enough; the more simultaneously activated, the more vulnerabilities there would be.

After the complete refining of the Celestial Poison Needle, Ji Yuan spent more than a month refining the magical treasure Heavenly Web.

Different from the incomplete magical treasure like the Celestial Poison Needle, the Heavenly Web was a "complete magical treasure."

Even as profound in mana as Ji Yuan, his cultivation having reached the late stage of Foundation Establishment, activating the Heavenly Web just once would consume half of his mana.

So, this magical treasure wasn’t something to be used unless absolutely necessary.

If once isn’t enough to defeat the opponent, then Ji Yuan would be the one being defeated!

After refining both magical treasures, Ji Yuan then spent time painting talismans and alchemy, and from this point on, he planned to store all the talismans and elixirs he created.

The Demon Dao invasion was imminent; no one knew what would come first, tomorrow or unexpected events.

Moreover, it was primarily because Ji Yuan now had a Level 3 [Spirit Vein].

A daily yield of 100 Mid-grade Spirit Stones, even if he used Spirit Stones for cultivation every day, he wouldn’t be able to spend it all.

Since Spirit Stones weren’t in short supply, there was even less necessity to sell them.

So, in the next half year, except for occasional trips to Hu Yue Island and Wan You Island, Ji Yuan went nowhere else.

Focusing wholeheartedly on cultivation.

With some help from the [Enlightenment Room], Ji Yuan finally comprehended another part of the "Sword Manual" again.

In other words, he was now able to further improve his cultivation.

Ji Yuan initially planned to travel again to find a place to condense the sword embryo, but the information he obtained from Li Changhe kept telling him.

The Demon Dao was frequently mobilizing troops for a large-scale invasion on Shang Mountain. It might be approaching soon.

Ji Yuan relayed this information to Dong Qian to help analyze it.

The cautious Dong Qian advised Ji Yuan to wait and see until the situation became clearer.

The detection of a sword embryo wouldn’t contribute much to Ji Yuan’s cultivation level.

There was no need to go out at this time and take such a huge risk.

Ji Yuan agreed, so after dual cultivation, he returned to Mist Island once more.

He continued to feed the Spirit-Devouring Bees, Frost Serpents, and Big Toad. During the period, he went out a few times and attended a few auctions in nearby towns to purchase various protective measures.

On a certain day. 𝗳𝚛𝗲𝕖𝕨𝕖𝗯𝚗𝚘𝕧𝕖𝗹.𝗰𝗼𝕞

To the west of the Shang Mountain ranges, amidst the mountains eternally shrouded in dark clouds, a shadow suddenly appeared.

His figure was not tall and was wrapped in a large black robe.

As soon as he appeared, the black clouds above his head began to roll violently, and streams of black smoke swirled and hovered around this mountain range.

He sat back, and white bones rose to form a mountain; the king sat on the throne.

At this moment, a ray of sword light suddenly rose from an unknown mountain top of Shang Mountain, streaking straight westward, slicing through countless cloud layers.

Finally, the sword light halted in front of the White Bone Throne, transforming into a man in a blue robe, holding a sword in one hand as he gazed at the person before him and asked:

"I wonder, White Bone Demon Monarch, what brings you from afar?"

The Demon Monarch on the White Bone Throne leaned slightly forward, smiling: "Two matters."

"One is to open the mountains, and the other... is to kill!"

As the words fell, the surroundings suddenly turned into a purgatory of white bones.

The blue-robed man did not speak, instead he slashed open the purgatory with a single sword, and then his calm words seemed to echo throughout the entire Shang Mountain.

"In the two thousand one hundred seventy-second year of the Sword Ruins, on the fifteenth day of the eighth month, Demon Dao... invasion."
