Di Bai slept directly for three full hours. When he woke up, he saw Di Jing as soon as he opened his eyes.

"Daddy," he quickly stood up and saluted.

Di Jing smiled slightly and asked, "How do you feel?"

"I've recovered, thank you Daddy" Di Bai felt his body, and a touch of joy crossed his face. At this moment, he had almost reached the peak of the first stage of refining tendons, which was the credit of Di Jing's drop of dragon blood.

Di Jing waved his hand aggressively, his own cub was polite, and he shared a lot of points for nothing.

"Ready to form the sword seal?" Seeing Di Bai's eager appearance, a smile also appeared on his face.

Di Bai nodded, he was indeed ready to forge the flying sword in one go. One is because his state is really good, and the other is that it has not been a few days since Tai's entry into Dongtian, and he really has no more time.

"I will protect the Dharma for you here, and I can seal it with peace of mind" Di Jing raised his forehead slightly, and then a red dragon shadow rose from his body, tightly coiling Di Bai's small courtyard.

The red dragon shadow scale armor has delicate hair, and two long dragon whiskers flutter in the wind, looking like a living real dragon, and it is very strange.

And Di Bai felt a little and found that his small courtyard seemed to have become an independent space, completely isolated from the outside world.

Feeling his father's methods, he immediately sat down cross-legged and began to prepare for the sword seal.

Forming a sword seal is not a trivial matter, even if he is extremely familiar with the Zhenlei sword seal, and he has also sealed against the enemy before, he still feels quite nervous.

After all, failure is not a simple matter of repeating the phrase.

But power is never in vain, it all comes at a price, and Di Bai understands this sentence very well. Especially for him, protecting the human race is not a simple sentence, but a heavy responsibility.

"Come on, it's up to you whether you live or die" took a deep breath, his dark eyes flashed a ray of thunder, and then the golden true qi in his body ran along the meridians in his body like a great river.

As soon as he touched the ring, a three-edged glass-like spar emitting a silver glow appeared on his hand, which was the empty spar and the container for storing the flying sword in the future.

Looking at the empty crystal in his hand, Di Bai held his breath and concentrated, and a spiritual sense wrapped around it, and then held it in front of him.

Immediately afterward, he began to make mudras according to his familiar feelings.

Unlike the last two seals, this time he had to engrave the runes on the empty crystal, which was more difficult and required more effort. Because the distance between the runes arranged on the empty spar cannot be bad in the slightest, which requires him to be more careful and more attentive.

However, it is not his style to retreat from difficulties, and when he thinks of the scene after he cultivated the flying sword, he feels full of energy.

A dark blue thunderbolt condensed between his hands.

Then, as soon as the spiritual sense was rolled, the empty spar was swept into the thunder. This is the first step in compiling the Thunder Seal, allowing his Thunder True Qi to impregnate the Void Crystal, so that its resistance to himself is minimized.

This step took a long time, so Di Bai was also ready to fight a protracted battle, just sitting there and single-mindedly maintaining the output of Lei Mang in his hands.

The glass-like empty crystal was wrapped in his blue thunderbolt, emitting a dazzling and deep blue light.

And with the passage of time, you can clearly see that tiny thunder and lightning lines slowly appear in the glass-like empty crystal, just like the meridians of the human body, and the thunder seems to be injecting vitality into it.

Seeing that the thunder and lightning lines began to appear, Di Bai was also overjoyed. This proves that his efforts are not in vain, and this step is not wrong.

The next thing to do is to fill the lightning pattern with empty crystals.

But this step is easy to say, but it's not that simple. Just like storing thunder for the little thunder dragon, he also needs to expend a lot of true qi to maintain the strength of the thunder between his hands.

And as the lines spread deeper and deeper, the more True Qi was needed, and he had no choice but to continuously increase the output of True Qi. For a while, the water level of the golden lake in the body continued to decrease as if the sluice gate was opened to release water.

Finally, it took a full hour, and the thunder and lightning finally succeeded in filling the empty crystal. Looking at the empty spar covered with thunder and lightning patterns like a work of art, a smile appeared on Di Bai's face, he finally succeeded.

However, when he felt that only half of the golden lake was left in his body, he couldn't help but sigh with emotion, he could be regarded as the third true qi like lake among the five types of true qi visions of cultivators, how could he be so useless.

But emotion is emotion, but he doesn't dare to be careless, and his spiritual sense is still floating in the air with the empty spar. The next step is the most important step, the compilation of the runes, and this most crucial step is not to be mistaken.

After a little breathing, and the true qi in his body was fully restored, Di Bai began to form mudras.

Since it was a codified rune, it was impossible for him to make several handprints in a row like last time, but he could only seal them one by one.

Therefore, I saw that his heart and hand were united, and slowly but firmly formed the first mudra.

"The First Seal - The Stinging Seal"

With a low shout, a blue rune appeared out of thin air. The mysteries of the runes are not only circulating endlessly in mid-air, but the breath coming from inside is even more overflowing to the most masculine and strong.

Then, Di Bai carefully manipulated the thunder talisman to approach the empty crystal. The engraving of this first rune is the most important thing, and it is also the most direct factor related to whether the subsequent runes can be successfully engraved.

Therefore, the position of this first rune must be extremely accurate, and it is best that there must be no deviation in the slightest.

Looking at the thunder patterns that slowly stuck to the empty crystal, even Di Bai felt quite nervous even if he had always been tenacious, but despite this, his spiritual sense was trembling at all, and he was still slowly and steadily controlling the thunder runes.

Di Jing on the side looked at it, and couldn't help but nod approvingly, the strong man is the most focused, and his cub can be so calm It really makes him feel quite gratified.

And Harley's face was also tense, as the only bystander who witnessed the creation and cultivation of this sword technique by the Emperor of Zhenlei, he knew the importance and criticality of this moment, but now he could only silently wish Di Bai.

Finally, in the expectant gaze of everyone, the first thunder pattern was pasted with the empty spar.

"Sting, stinging, stinging"

As soon as the rune touched the spar in the sky, it suddenly burst out with a strong and piercing lightning, and then two arm-thick thunderbolts directly struck. This scene made Di Bai's heart shrink suddenly, and he secretly prayed that nothing would go wrong.

But fortunately, there were no uncontrollable factors in the future, and I saw that after the rune was pasted with the empty spar, it slowly melted in. Then the lightning pattern inside connected with the rune pattern, and in an instant, the entire empty spar lit up.

Looking at the lines connected to the thunder rune in the empty crystal in front of him, Di Bai also breathed a sigh of relief, and finally succeeded.

He turned his head to look at his father and Harley, both of whom smiled encouragingly.

After a little breathing, he continued with the process he had just begun.

"The Second Seal - The Seal of Fulei"

With a low shout, another blue thunder pattern was suspended in midair. Different from the previous thunder pattern, the aura of this thunder pattern is more restrained, but the energy contained in it is also more violent.

With the previous successful experience, Di Bai was also very proficient, and after aligning the position, he directly manipulated the thunder pattern to paste the empty spar.

The action is done in one go, and there is no delay for half a minute.

And he seemed to be really like a divine help, and this thunder pattern was directly attached to the empty spar without any deviation. As a result, the second thunder pattern slowly sank into the empty spar, and the light in the spar was a little brighter than just now.

With the successful engraving of two thunder patterns in a row, not only Di Bai, but also Di Jing and Harley were also relieved. In this way, the eight thunder patterns are not very difficult.

But Di Bai himself became more and more calm, and he knew that he could not really relax until the last moment.

Therefore, without saying a word, it is dry, and directly begins to condense the next thunder seal.

"The Third Seal - Breaking the False Seal"

"The Fourth Seal - The Seal of the Heavens"

......................

In the next three hours, he pinched five thunder seals in a row, and all of them successfully engraved the thunder seals on the empty crystal.

Looking at the seven thunder seals that had been engraved in front of him, the thunder inside was shining, as if it was a living empty crystal.

Di Bai took a deep breath, and the gestures of his hands changed again, and an extremely mysterious and complex handprint was formed by him.

"The Eighth Seal - Zhen Lei Seal"

"Boom Card"

A silver rune appeared out of thin air with endless thunder and thunder, and the surface of the silver rune was constantly flowing with light and silver thunder and lightning, showing his majesty like an emperor in thunder.

Looking at the eighth and final thunder mark in front of him, he didn't hesitate. As soon as the spiritual sense pushed, the thunder seal was accurately attached to the empty crystal.

"Thorn stab stab stab"

As soon as this last thunder seal was attached to the sky spar, the entire air spar instantly burst out with extremely strong thunder light. Then, countless finger-thick silver thunderbolts continued to split in all directions.

And this silver thunderbolt seemed to be more difficult than Di Bai's azure thunderbolt. Several silver thunderbolts that slashed into Di Jing's crimson dragon shadow did not collapse immediately, but instead spread towards the dragon shadow's whole body, with a posture of infiltrating the dragon shadow's body.

However, Di Jing's strength is here, although these silver thunderbolts are powerful, they only last for a moment as a source of water and then disperse.

But this scene made Dedi Jing's eyes narrow slightly, this extremely spiritual thunder and lightning was the same as the sword intent that pierced the fox king that day, both of which were looking for the opponent's weakness in order to achieve the result of a single blow.

"It's been a long time since I've seen such a spiritual thunderbolt," Di Jing pinched a piece of silver thunder and lightning in his fingertips, and felt it carefully before letting it go.

"This is the characteristic of Yang Ba's Thunder, Di Bai is Yang Jiu, and he will be even more violent," Harley explained, after getting along just now, he and Di Jing can be regarded as friends, so they speak much more naturally.

Hearing this, Di Jing nodded slightly in thanks.

But Di Bai was at the most critical moment, after the Zhen Thunder Seal entered the empty spar, the entire spar seemed to be truly activated, and the next moment it directly rushed into his forehead.

After that, he felt as if his eyebrows were pressed against a red-hot old iron, and the iron had now reached into his head, constantly stirring his brain.

At this moment, he vaguely remembered a home-cooked snack in Dongtian - roasted brain flowers. It's really retribution, I used to think this dish was delicious. But at this moment, he swore that as long as he survived, he would never eat again.

It's really empathetic, it hurts.

The pain lasted for a long time, so long that Di Bai was a little numb.

However, at this moment, the role of his military cultivation is reflected. It seems that because the military technique and this sword technique complement each other, no matter how much the empty spar is tossed in his skull, no matter how painful it is, his skull is still safe and sound.

And, as time goes on, that pain lessens.

"The empty crystal itself has spatial attributes, and after entering Di Bai's body, it will turn into the size of a speck of dust. It's now in contact with his spiritual sense, just get through it," Harley explained, seeing Di Jing's worried gaze.

This step is essential, unlike sealing in the dantian. Sealing in the center of the eyebrows can effectively refine spiritual consciousness, so be sure to establish a connection with spiritual consciousness first, and it is normal to be a little painful.

If Di Bai could see the inside of his eyebrows, he would find that the almost invisible blue light was connected to the empty crystal at one end, and some areas in the depths of his brain were connected to the other end.

And with the increase of these rays, he felt that he was simply uncomfortable now, completely inversely proportional to the pain he had just had.

Finally, as if the connection with Di Bai Zhihai had been completely established, the blue light stopped increasing.

Then, I saw a blue thunder light accompanied by the roar of thunder and lightning rising from Di Bai's body, and a whirlpool full of dark clouds directly appeared in the air of the Di clan's land, and the thunder in it was bursting, and the thunder was raging.

"It's heaven's punishment" Harley saw it, and his little face suddenly panicked.
