Now that you have betrayed the sect, who will still pamper you?.

The City of Ten Thousand Calamities.

Four streaks of rainbow light swept in from the horizon. As they approached, they entered the city discreetly without alerting anyone and dispersed separately.

Jiang Han returned to the villa where he was temporarily staying. The two people outside were still chatting, and Xu Wenzhou had even joined them for drinks. However, the three of them looked rather gloomy and sighed after saying a few words.

Without disturbing the three's conversation, he slipped into the courtyard.

After sitting down in the quiet room and resting for a while, Jiang Han raised his right hand, and eleven demon cores of different colors floated up.

Nine of them, each about the size of a fist and of different colors, were the inner cores of ordinary demon kings, while one, a fiery red ball about the size of a bowl, was the inner core of the Vermilion Bird.

As for the only one, which was purple and red, with flashes of lightning and snakes of electricity, and about the size of a bucket, it was the inner core of the ancient thunder dragon.

These demon cores have unique effects, helping him to condense a law-based thunder dragon and even touch the origin of thunder.

The demon core of the Mountain-Shaking Demon King was devoid of spirituality because its primordial spirit had escaped, which prevented the runes within the Thunder Dragon's body from becoming complete.

Now that he has eleven fully-formed demon cores, he has enough to try slowly. If that doesn't work, he can look for other methods.

However, before that, it is necessary to stabilize the Thunder Dragon with a Thunder-attribute magic weapon; otherwise, if the Thunder Dragon grows too much, it is very likely to go berserk and collapse.

Thinking of this, Jiang Han raised his hand and took out the Thunder Dragon Prison Suppression Seal. The Thunder Seal was only the size of a palm at this time. After hovering in front of him for a moment and rotating, it turned into a stream of light and entered his dantian.

Within her dantian, the sword spirit was already prepared. As soon as the purple light appeared, she raised her hand and grabbed it, quickly drawing several restrictions to imprint into the lightning seal, and then threw it towards the Law Lightning Dragon.

The Thunder Dragon couldn't wait any longer. Seeing the purple light coming, it stretched out its body, opened its mouth, and swallowed the Thunder Seal.

In an instant, countless bolts of lightning erupted from Lei Long's body, and his dantian instantly transformed into a sea of ​​lightning.

Besides the lightning, runes flashed across the dragon's body, and its body began to writhe violently, swam wildly in the sea of ​​lightning, and roared from time to time.

"Hold your breath and concentrate, use your divine sense to stabilize the Law Thunder Dragon, leave the rest to me."

The sword spirit shouted and flashed above the thunder dragon. With one hand, it pressed down and cast a restriction to imprison the thunder dragon. With the other hand, it raised its fingertips and drew a very complex ancient rune in front of it.

Jiang Han did as instructed, his divine consciousness materializing above the thunder dragon's head. He sat cross-legged and gradually merged into the thunder dragon's body.

As he entered, a violent and chaotic feeling arose in his heart, as if he wanted to break free of his cage and shatter the world.

In just a moment, a large amount of black smoke burst out from his eyes, and even the purple light of his divine sense was suppressed.

Just then, a golden light burst forth from the heart lake, quickly rushing into the eyes and dissolving all the black smoke.

His consciousness quickly returned, the golden light in his eyes faded, and his mind became completely stable. The thunder dragon stopped roaring and wandering, obediently remaining still in place, cooperating with the sword spirit to stabilize itself.

……

Time flies, and three days have passed in the blink of an eye.

The Law Thunder Dragon had already merged with the Thunder Dragon Prison Seal. Although it was a pity to lose this top-grade immortal treasure, Jiang Han had enough immortal treasures in his possession, so he wasn't too heartbroken.

After the Thunder Dragon stabilizes, it absorbs the demon core to complete the Thunder Rune.

As a demon king's inner core was swallowed by the black hole, the lightning rune that was just one step away from being formed began to emerge on its own. In the blink of an eye, it broke through the final step and condensed into a perfect ancient rune.

But it's not over yet.

As the power within the demon core continued to be absorbed, the runes changed once again.

It is no longer simply outlining the shape of runes, but gradually evolving into lightning.

Moreover, it wasn't just the runes on Lei Long's body that changed; this time, even the azure lightning within his body began to gradually transform into the shape of lightning runes.

The Thunder Dragon's aura surged and circulated within its body with each breath, gradually transforming into streaks of azure lightning snakes that began to twist and begin to form the rudiments of runes.

"Can it be stronger?"

Jiang Han noticed the changes in Yuan Power, pondered for a moment, and then continued to inject the demon core to help the runes continue to evolve.

As each demon core was melted and absorbed, the Thunder Dragon became more solid and stronger, indistinguishable from a physical entity. The azure lightning within its body also completely transformed into the form of lightning runes.

What now flows through his body is no longer illusory thunder dragon aura, but cyan thunder runes resembling runes.

Countless lightning runes converged into rivers, surging powerfully within the body, while the lightning dragon became a transit station, continuously swallowing the lightning rivers, circulating them throughout the body, and then expelling them into the dantian.

Each time lightning was emitted, the runes would brighten slightly, and the lightning aura on them would become purer.

In addition, a purple lightning rune appeared on the back of Jiang Han's hand.

He raised his right hand, and a foot-long lightning dragon emerged from his body, coiling around the back of his hand and continuously moving around the lightning runes.

Although the Thunder Dragon was much smaller, its aura was much more profound and harmonious, more than twice as profound as before.

After all, it was the power of the demon core of the twelve demon kings. After condensing into thunder runes, it seemed to have given him a kind of thunder and lightning authority.

Now, every move he makes can cause the laws of thunder to tremble. He no longer needs to expend any energy; with just a thought, he can command countless bolts of lightning to his advantage.

This is already the limit of the Thunder Law. If he can take another step forward and fuse these runes into one, he will be able to touch the true origin of thunder.

At that time, he will no longer need to use the laws to manipulate the power of thunder, but will transform into thunder and embark on the true path of thunder!

Besides the Thunder Law, after absorbing so many demon cores, his cultivation level has also reached the peak of the mid-stage of the Nascent Soul realm. He only needs a small opportunity to break through his realm and advance to the late-stage of the Nascent Soul realm!

……

"The Law of Thunder truly lives up to its reputation as the most domineering law of attack. Although it completely consumed the demon core, its power is indeed satisfactory."

Exhaling a breath of stale air, Jiang Han conjured countless lightning runes in the quiet room with a thought, densely packed and occupying every inch of space.

Each of those lightning runes carried a terrifying aura that sent chills down one's spine; when it erupted, it was comparable to half the power of his sword light.

If so many thunder runes were unleashed simultaneously, even without using the Yin-Yang Immortal-Slaying Sword, the Nine-Headed Demon Emperor would be nearly killed.

His gaze swept over the area, and the lightning runes vanished swiftly, silently, entirely at his command.

Jiang Han nodded in satisfaction, then raised his hand and waved it. Immediately, more than twenty streams of light flew out from his storage ring and landed in front of him, transforming into a series of immortal treasures that floated motionless.

Those demon kings were wealthy. Although they only had a few rare and precious materials in their storage rings, each of them possessed a celestial treasure.

There are two or three items at most, and one at least, making a total of twenty-eight items!
