Cultivation of Immortality: Start by Improving Spiritual Root Qualifications

Chapter 818: Refining the Thunder Sword, the Blood Demon is complete!
"But I've only heard of two places that can meet this standard!"

"One is the 'Thunder Prison', one of the seven forbidden areas in the legend. It is said that it is a world of thunder and lightning. The thunder energy contained in it is naturally enough for the Thunder Sword to be upgraded to the best grade!"

"Besides that, only the ten thousand feet deep underground lightning pool in the Samsara Demon Palace can meet the requirements!"

But these two places,

One of them is missing, and the other is in the Samsara Continent. Besides, the Six Paths Demon Lord in the Samsara Demon Palace is not an easy person to talk to.
Even if Yun Ku Tianjun came forward, he might not necessarily give in.

"Isn't the Samsara Demon Palace a demonic sect? How could it regard a pool of thunder as a treasure? Isn't this incompatible?" Zhou Xun was extremely puzzled.

In theory, the way of thunder can extremely restrain the way of magic.

"This is the extraordinary thing about the Samsara Demon Palace. It is said that the core inheritance of the Samsara Demon Palace is the ability to transform into heavenly thunder for one's own use, stimulating the magic power of demonic thunder. It is extremely strange!"

The Six Paths Demon Lord is an extremely rare thunder dharma body.
Hearing this, Zhou Xun couldn't help but widen his eyes. He himself practiced the way of thunder, so he naturally understood his domineering nature very well.
It is incredible that the Samsara Demon Palace can combine the magic and thunder to create a new skill.
Thinking of this, he couldn't help but communicate with the Blood Demon Ancestor.

"Senior, you are knowledgeable and experienced, have you ever heard of this magic thunder power?"

"What? There is actually such a set of skills circulating in the human world!" said the Blood Demon Ancestor in surprise.

"Back then, in the fairyland where we were, an extremely strange cultivator appeared. This person had extremely strange magical powers."

"He is clearly a cultivator of the Dao of Thunder, but he is just like a cultivator of the Dao of Demons, specializing in hunting down low-level cultivators and obtaining their souls for cultivation!"

"Many disciples from various sects have fallen victim to his murderous hands!"

"Then all the major forces joined forces to capture this person, but in the end he escaped and disappeared without a trace!"

“Now it seems that the man may have escaped into the human world and left his legacy here, which is why the Samsara Demon Palace came into being!”

"Oh, right, this person was known as the Demon Lord of Samsara!"

After hearing this, Zhou Xun understood clearly in her heart, and also made a judgment that this so-called Samsara Demon Palace is most likely the inheritance of the Samsara Demon Lord.
He even created it.

But since it was a place full of such vicious people, he naturally didn't dare to go in. It seemed that the only place left was the Thunder Prison.

"Does he have to wait for more than ten years, and then invite Master Bailian to go into the Thunder Prison together to refine the Thunder Sword for him?"

While he was thinking, Master Bailian spoke again,

"If Lord Zhou is sure that he wants to refine this sword again, then I can refine it for you. When there is only one step left, seal the atmosphere and wait for Lord Zhou to reach a place full of thunder energy before absorbing the thunder energy."

"At the same time, after I refine it, this sword can no longer be used before it absorbs enough thunder energy. Otherwise, the seal will be invalid and I will never be able to advance in the future!"

"I have explained the pros and cons clearly. I wonder if Palace Master Zhou wants to continue refining this sword!"

Hearing this, Zhou Xun couldn't help but weigh the pros and cons.
In ten years or so, I will have to go to the Thunder Prison. There must be enough thunder energy there for the Thunder Sword to be upgraded.
Even if it is refined at this time, the effect will not last too long.
Besides, now he has the Five Heart Demons and Blood Demon General in his hands, so it doesn't matter if he can't use the Thunder Sword.
After much thought, he finally decided to refine the sword, so he bowed to Master Bailian:

"Then I'll trouble you, Master!"

Master Bailian nodded slightly, with a hint of appreciation in his eyes, and he approved of Zhou Xun's decisive decision.

He stretched out his hands with his palms facing up. Zhou Xun understood and gently placed the Thunder Sword in the master's hands.

In an instant, a powerful and pure strange spiritual power surged out from Master Bailian's body and tightly wrapped the Thunder Sword.

This spiritual power was like materialized spiritual liquid, rolling and flowing around the Thunder Sword, constantly seeping into every texture and crevice of the sword body.

"Water Method for Refining Equipment!" A name popped up in Zhou Xun's mind. This was an extremely rare school of refining equipment. He had only seen it in classics.
I didn't expect to see it with my own eyes today.

Master Bailian closed his eyes tightly, sweat slightly oozing out of his forehead, and devoted himself to the refining process.

He muttered something, and strange runes flew out of his mouth and merged into the spiritual power that wrapped the thunder sword.

The runes flashed with mysterious light, interweaving with spiritual power, constantly transforming the internal structure of the Thunder Sword.

Under the influence of this powerful force, the Thunder Sword began to tremble slightly, and the runes on the sword body seemed to be activated, emitting an even more dazzling light.

Zhou Xun stood aside, holding his breath, watching all this intently.

At the same time, Master Bailian stretched out his left hand and grabbed the air. A rare treasure emitting a faint light appeared in his hand.

It was the Thunder Soul Refined Gold, which contained extremely pure thunder power inside. There were traces of lightning flashing on the surface, as if it was beating with life.

With the spiritual power of Master Bailian activated, the Thunder Soul Gold began to gradually melt and turned into a flowing golden lightning, which slowly flowed towards the Thunder Sword.

Wherever the golden lightning went, the spiritual energy around the Thunder Sword was also affected, becoming more violent and forming small spiritual energy vortices.

After the golden lightning merged into the Thunder Sword, the sword body began to tremble violently. Master Bai Lian quickly formed seals with his hands and kept chanting obscure spells, gradually guiding and integrating the violent power.

The surface of the lightning sword glowed brighter and brighter, and the original silver runes were now stained with a light golden color.

After an unknown amount of time, Master Bailian suddenly opened his eyes, and a gleam of light flashed in his eyes.

He shouted loudly and waved his hands quickly. The spiritual power wrapped around the Thunder Sword shrank instantly and stuck tightly to the Thunder Sword.

Then, he shouted at Zhou Xun:
"Palace Master Zhou, I need a drop of your blood!"

Zhou Xun followed his instructions, forced out a drop of blood, and hit the Thunder Sword.
The light of the lightning sword suddenly became more dazzling, and at the same time it was surrounded by a faint blood color, and a vague sense of connection was transmitted from it!

at this time,

Master Bailian changed his spell, pinched out a silver rune, and hit the lightning sword.
Almost in an instant, the originally jumping thunder sword suddenly became silent, like an ordinary item.

"Huh..." Master Bai Lian let out a long sigh, a trace of fatigue appearing on his face.

He handed the Thunder Sword to Zhou Xun and said, "Master Zhou, the sword has been refined. Now we just need you to go to a place full of thunder energy and let it absorb enough thunder energy, and then it can be upgraded to the best quality."

"Before absorbing the thunder energy, you must not use this sword, otherwise the seal will be invalid and there will be no possibility of promotion."

At the same time, he taught Zhou Xun the method of removing the seal and absorbing thunder energy.

Zhou Xun bowed to Master Bailian and said:

"Thank you for your help, Master. How much is the reward?"

Hearing this, Master Bailian waved his hand.
"It is an honor for us weapon refiners to be able to personally refine materials such as 'Thunder Soul Crystal'. As for the reward, please do not mention it again!"

Hearing this, Zhou Xun nodded without any pretense.

"Thank you very much. If you need me in the future, Zhou Xun will do his best." Then Zhou Xun returned to Shan Xionghai's residence and stayed for a full month before saying goodbye.

After returning to the East Desert, Yu Siyue had already adapted to the life in Wangchuan Lake, and the Jade Water Golden Eyed Beast also liked the environment of Wangchuan Lake.

After all, the spiritual veins here are of the fourth-order middle grade.
And it is still rising.
According to Zhou Xun's estimation, it would take at most two hundred years to be promoted to the fourth-grade upper grade.
It was nothing like the river he had been in before.

Not to mention the magical herbs and fruits that were everywhere on the island in the center of the lake. Zhou Xun didn't mind eating one or two occasionally.

Not long after,
One day, the Blood Demon Ancestor found him.

"What do you want, senior?" Zhou Xun asked.
"Zhou boy, do you still remember the two blood demon generals you buried?"

"Senior, are you talking about the two in the Yin Qi Land?" Zhou Xun recalled that after killing Master Bai Gu, Zhou Xun brought his son's body back to the East Desert.

Two thousand miles east of the island in the center of the lake, in the land of Yin Qi, two blood demons were buried.

Now, more than ten years have passed, and it has already been nurtured to perfection. Now is the time to take it out!

"Yes, it's those two!" The Blood Demon Ancestor nodded.

"Okay, I have nothing to do today, so I'll set off!"

As he spoke, his figure flashed and he appeared above the cave. With a thought,
"Wow—"

A blue-purple flying wing with a wingspan of more than ten feet spread out, with lightning flashing on it. It was his Thunder Wings.

As his cultivation level increased, the power of this treasure also increased, and its speed became faster and faster. Now it even had a hint of spatial power.
He had a premonition that as long as his cultivation base was promoted to the late Nascent Soul stage, the power of the Thunder Wings would also increase greatly.
By then he will be able to use his Thunder Wings to perform the art of teleportation and move his body across space.

Driven by this treasure, in less than a quarter of an hour, Zhou Xun arrived at his destination - the place where the yin energy of the Blood God was nurtured.

Two figures fell from the sky.
The Blood Demon Patriarch looked around the valley and nodded slightly:
"If this extremely Yin Blood Demon Formation is finally reaching perfection, the Yin veins in this Yin-filled land are also in good condition!"

When Zhou Xun heard the praise from the Blood Demon Ancestor, he was secretly proud in his heart, but he smiled modestly on his face:
"Thank you for your praise, Senior. However, I spent a lot of effort to arrange the formation in order to nurture the Blood Demon General. Compared with the great formations in the immortal world that you have seen, it is probably not worth mentioning."

"Besides, if it weren't for the improvements made by our predecessors, we wouldn't have the current momentum!"

"Let's take a look at the two blood demon generals first!"

Zhou Xun heard this and nodded.
He made hand gestures and pointed at the formation. Then, the dark negative energy in the formation instantly returned to the ground.

Not far ahead, two blood-red heads appeared on the ground, and their bodies were buried underground.

The Blood Demon Ancestor's eyes were as fast as lightning, instantly locking onto the Blood God General. He narrowed his eyes slightly, paced slowly around the Blood God Son, and investigated carefully.

"These two blood gods..." The Blood Demon Patriarch pondered for a moment.

“Although he has already achieved great success, his cultivation is lacking. He is only at the peak of the fourth-order lower grade. Compared with the first-class and fifth-class, he is far behind. If he joins in hastily, it will make the formation unbalanced!”

"Listen to the senior, there seems to be a way to solve it!"

"Of course!" The Blood Demon Ancestor smiled slightly and flipped his palm.
He took out a piece of Blood Demon Crystal, which turned out to be a fourth-grade top-grade Blood Demon Crystal refined from the corpse of the Palace Master Qingyang who was killed that day.

"Use this fourth-grade high-quality blood demon crystal as a guide, split it into two, and inject the blood demon power contained in it into the bodies of these two blood demon generals."

“Although it’s a bit wasteful, we can harvest two fourth-level mid-grade blood demon generals and form the Big Dipper, which can at least increase our strength by 50%!”

"Even compared to the Five Demons, I'm afraid it's not much different!"

"Please do as you please, senior!" Zhou Xun stepped aside.

The Blood Demon Patriarch formed seals with his hands, and several runes floated out and merged into the yin energy surrounding the Blood God General.

In an instant, the Yin Energy that was originally flowing slowly around the Blood God Son became turbulent and formed a small Yin Energy vortex.

The Blood God's head trembled slightly, as if he was actively absorbing the Yin energy that was strengthened by the runes.

Its eyes were originally wide open, but now they were glowing with a faint blood-red light, and its aura became increasingly condensed.

"It's now!"

With a loud shout, the two Blood Demon Generals suddenly opened their mouths, and the Blood Demon Ancestor then accurately put two cut Blood Demon Crystals into their mouths.

In an instant, the two blood demons were surrounded by blood light, and their bodies that were originally buried in the ground shook violently, and they actually broke out of the ground by themselves!

Their bodies were covered with dark red scales, with a pair of bloody wings growing from their backs and strange bloody runes appearing on their foreheads.

"Senior's method really opens my eyes." Zhou Xun admired sincerely, his eyes full of curiosity.

The Blood Demon Ancestor smiled and explained:
"This rune of mine can stimulate the Blood God's instincts, allowing it to absorb Yin energy more efficiently and accelerate its growth."

"At the same time, the original potential will not be damaged. With this half piece of high-quality blood magic crystal, a breakthrough will be a piece of cake!"

"Next, we just have to wait!" After saying that, he waited quietly at the side.
At this time, only lines of Yin energy were seen rolling and continuously pouring into the bodies of the two new blood demon generals.

With the continuous infusion of Yin Energy, the blood runes on the two blood demons became brighter and brighter, gradually forming blood light patterns.

Their bodies were also expanding at a speed visible to the naked eye, gradually growing from the original three meters in height to more than five meters.

Then,

A powerful aura emanated from the two blood demons.
Fourth-grade intermediate quality, here we are!
Seeing this, the Blood Demon Ancestor was overjoyed. He pointed at the Blood Demon Bag and five red shadows flew out.

The Blood Demon Patriarch growled:
"Beidou returns!"

He just made a hand gesture and seven blood-red light pillars dropped from the sky, covering the seven blood demon generals.

The two newly refined blood demon generals will occupy the positions of "Kai Yang" and "Yao Guang" respectively, and will be connected with the Qi of the other five blood demon generals.

"boom--"

An astonishing pressure erupted instantly, and a blood-colored light curtain formed between the seven blood demon generals, and the pattern of the Big Dipper could be vaguely seen flowing in it.

The negative energy of the entire valley was drawn away, forming a huge vortex.

Zhou Xun felt this might and couldn't help but take a breath: "The power of this Beidou transformation is beyond imagination!"

The Blood Demon Ancestor nodded with satisfaction: "Yes, although these two new Blood Demons are only of the fourth-level middle grade, after being integrated into the Big Dipper Formation, their overall power is no less than that of the Five Sons of the Concentric Demon."
