After leaving the Falling Thunder Valley, Pei Ze casually threw a series of spells to the three Thunder Abyss giants, such as the Weak Energy Technique, the Sleeping Technique, and the Snake Pattern Magic Seal.

After a set of combos, the three Thunder Abyss giants who were struggling violently and roaring suddenly fell silent, fell into a deep sleep and remained motionless.

After that, Pei Ze and the three of them quickly moved away from the Falling Thunder Valley, ran all the way out of thousands of miles, found a remote place with their backs against the cliff, and put down the three Thunder Yuan giants.

"We're all going to stay here for the next while, and I'm going to do some experiments."

Pei Ze turned around and said to Su Ya and Peng Yan.

"Don't bother me if it's okay."

"Yes, sir."

Pei Ze didn't say more, manipulated the earth-based energy particles, and quickly dug a spacious cave under the cliff.

Immediately after, he drew a large amount of blood from the three Thunder Abyss giants and plunged headlong into the cave.

Su Ya and Peng Yan began to set up camp.

If you're going to be here for a long time, you'll have to set up a makeshift camp.

As for the three Thunder Abyss Giants, they were dragged aside by the two.

Most of the bodies of the three Thunder Abyss Giants were bound by the Silver Star, and they had been hit by spells, so they didn't have to worry about breaking free when they woke up.

In the cave, Pei Ze took out various experimental tools with his hands while meditating in his heart.

"Omniscient, calculate the technique of extracting the bloodline of the Thunder Abyss Giant to strengthen yourself."

[A task has been created, and the technique of extracting the bloodline of the Thunder Abyss Giant to strengthen itself has begun, and it is estimated that it will require 212.5 energy level spiritual power]

Pei Ze nodded slightly, and did not hesitate to consume mental power to accelerate, and completed the calculation in an instant.

After consuming the knowledge that came to his mind, Pei Ze began to refine his blood.

About an hour later, a bottle of refined and purified bloodline elixir was freshly baked.

Pei Ze drank the potion without hesitation.

As the liquid entered his abdomen, a thin arc of electricity suddenly burst out from all over his body, crackling.

Having had the experience of using the blood of the Thundering Beast to strengthen it before, Pei Ze had already prepared this time, and a layer of thunder energy particles surrounded his body, blocking the escaping arc and avoiding damaging the things on the experimental table.

He watched the changes in his body.

In the silent silence, the body is getting stronger little by little, and the density of muscles and bones is gradually increasing.

The perception of the surrounding thunder energy particles has also become more acute, so much so that the skin has a faint paralyzing feeling.

After a few moments, the strange feeling slowly dissipated.

Pei Ze breathed a long sigh of relief and said silently:

"Omniscience, detect my current condition."

[Spirit 222.17]

[Constitution 192.24]

"The physique has increased by more than four energy levels. Mental power has also increased! ”

A flash of surprise flashed in Pei Ze's eyes.

The increase in physique was as he expected, and the increase in the energy level of more than four points was quite decent, after all, the Thunder Abyss Giant itself had a powerful physique comparable to a fifth-order legend.

But the increase in mental power was an unexpected surprise.

And it's an increase of 1.1 energy levels!

In terms of his current mental strength, this increase was not low, stronger than the effect of many rare and exotic objects.

"Could it be because of the Thunder Abyss Giant's ability to control the thunder element?"

Pei Ze was thoughtful.

Anyway, it's good news.

Pei Ze was full of motivation and continued to refine the blood of the Thunder Yuan Giant.

Hundreds of liters of blood, and in the end, only five vials of blood potion were refined.

Fortunately, the Thunder Abyss Giants were large in size and had a lot of blood, and after the materials were consumed, Pei Ze went out to draw blood again, and by the way, he continued the Sleeping Technique and the Weak Energy Technique on the three Thunder Abyss Giants.

Before returning to the cave, Pei Ze casually threw Peng Yan a bottle of blood elixir.

"This potion can enhance the physique and increase the affinity of thunder energy particles, but the effect of the medicine is a bit strong, so you'd better only take a small sip at a time."

Peng Yan was immediately overjoyed, carefully holding the bloodline elixir, and said happily: "Thank you, my lord!" ”

Su Ya on the side showed a look of envy when she saw this.

Pei Ze saw it in his eyes and said, "When I am free, I will refine a suitable bloodline potion for you." ”

Su Yaxi said: "Thank you, sir!" ”

Time flies.

More than a month has passed in the blink of an eye.

Under the enhancement of the bloodline elixir, Pei Ze's physique quickly broke through the 200 energy level and soared to as much as 245.5 energy level.

Recently, when he practiced the omniscient breathing method, he already had a faint feeling that he was about to break through again.

In addition to this, the spiritual power has also increased to the 242.87 energy level.

Excluding the increase caused by meditation, the bloodline potion increased his mental power by a total of 11.3 energy levels.

It's a pity that after this, the effect of the bloodline potion is minimal.

"It seems that this is the limit."

Pei Ze felt a little pity.

However, after thinking about it, the Thunder Abyss Giant's bloodline elixir can enhance spiritual power is an unexpected joy, and you can't ask for too much.

Having settled down, he began to study the changes of the lightning runes.

First of all, the normal state, with his physique alone, the lightning runes he could withstand skyrocketed to one hundred and twelve.

This is almost the level that can only be achieved after the fusion of Silver Stars before.

And now fused with the Silver Star, the lightning runes that can withstand it have soared to one hundred and eighty-five.

The limit state is as high as 197!

"From this point of view, with the activation of the Silver Body, the limit number of lightning runes should exceed three hundred!"

Pei Ze had a happy smile on his face.

It was in vain that he made a special trip to the Shadow Realm, and the bloodline effect of the Thunder Abyss Giant was really strong.

In the past, when he crossed the level to fight, he had to activate or even burn the alchemy nick, but now he was confident that he could defeat the third-level wizard without using the alchemy nick.

After a while, Pei Ze came back to his senses from his joy.

"The matter between the Thunder Yuan Giants and the Nether Crow Group has been concluded, and now only the Pei family is left, and when they are resolved, they will return to Dawn City to retreat, and strive to break through to the second-level crystallization stage as soon as possible."

Pei Ze's eyes flashed slightly, summoning the eye of omniscience.

The progress of creating new runes has been completed for the most part, and there is only a little more than a hundred energy levels of spiritual power.

Seeing this, Pei Ze did not hesitate to expend his mental power to speed up and complete the task in an instant.

A large amount of information appeared in his mind out of thin air, Pei Ze closed his eyes and digested it for a moment, and then began to engrave the runes.

This rune, derived from the shadow dragon egg, can be engraved on the spirit crystal after improvement, so that the spirit crystal can absorb the free energy particles around it at all times, and then increase the spirit power.

Although the growth rate is very slow, not to mention the mystic method of visualization, even the meditation of ordinary wizards is not comparable, but it is better to last, and it can grow slowly every moment.

Unlike normal meditation, after a while you can't continue and you have to rest.

In general, over a long period of time, the efficiency of the runes in improving spiritual power is only higher than that of ordinary meditation, and even not much worse than that of the secret method of visualization.

About half an hour later, Pei Ze successfully completed the inscription.

There are a total of two runes, each occupying a crystal surface of each of the two spirit crystals.

"Since it's a rune derived from a dragon egg, it's called a dragon pattern."

Pei Ze struck while the iron was hot and began to test the effect of the dragon pattern.

He was pleasantly surprised by the results.

The dragon pattern and meditation do not conflict, and in other times other than daily meditation, the dragon pattern can still absorb energy particles at all times to increase mental power.

At the end of the day, Pei Ze's spiritual power increased by 0.58 energy levels, almost twice as much as before.

"At this rate, it will take about eight months to reach the crystallization standard."

The corners of Pei Ze's mouth raised slightly, the original time of nearly 16 months has now been shortened to only 8 months, which is already very good.

Moreover, when the third spiritual crystallization is condensed, and one more dragon pattern is inscribed, the efficiency of automatic spiritual power growth will be further improved, forming a virtuous circle.

It can be said that with this dragon pattern alone, his trip to the Shadow Realm can be called a bumper harvest.

Leaving the cave, Pei Ze called Su Ya and the two of them, and took the Thunder Yuan Giant to rush towards the Falling Thunder Valley.

He's not a demon either, and since the blood of the Thunder Abyss Giants is useless, it's time to let them go.

The poor Thunder Yuan Giant was severely drained every few days during this time, and he had to hit the last few spells every day, no matter how strong his physique was, he couldn't withstand such a toss, and he was already weak, even if Pei Ze let them go, they wouldn't have the strength to walk back to Thunder Valley.

Pei Ze simply did it kindly to the end and sent them back to Thunder Valley.

Coming to the Falling Thunder Valley, as soon as he stepped into the valley, Pei Ze heard a roar from afar inside, faintly mixed with a thunderous roar, as if someone was fighting with the Thunder Abyss giants.
