Chapter 63

"Ah... damn it, refine it for me." Huang Yu shouted, his hair standing on end.

"Refine, refine, refine, refine it all." The strong belief and will made Huang Yu crazily运转 the Thunder Dragon Technique, continuously refining the terrifying heavenly thunder power for his own use.

But even so, the heavenly thunder power was still too terrifying, overwhelmingly vast, and impossible to refine. If this continued, his dantian wouldn't be able to withstand it and might burst.

"What should I do?"

"Master, don't worry. This thunder tribulation power isn't for you to cultivate, but to advance the Purple Extreme Sword and the Thunder Dragon Technique." At this critical moment, Lulu finally spoke.

"Then what are we waiting for? Hurry up, I can't hold on much longer." Huang Yu shouted loudly.

"Master, don't be in a hurry. It's just a little more, just a little more."

"How much is a little more? Hurry up." Huang Yu felt his dantian starting to stretch. In a few more breaths, it would probably explode. His entire body and internal meridians were almost destroyed by the terrifying thunder tribulation power. The three thunder dragons cultivated by the Thunder Dragon Technique kept absorbing, but couldn't withstand it anymore.

"Alright."

Hearing Lulu's voice, Huang Yu relaxed, feeling the heavenly thunder power in his body weakening and becoming gentle, all surging towards the direction of the Purple Extreme Sword.

"Ding, congratulations, the Purple Extreme Sword has advanced, transforming into an Earth-grade weapon."

Earth-grade, this is an Earth-grade weapon. Huang Yu was extremely happy. The transformation of the Purple Extreme Sword into an Earth-grade weapon made him feel a closer connection to it, as if it were a part of his own body. Moreover, the powerful strength made Huang Yu feel invincible with the sword in hand.

The fifth wave of the thunder tribulation passed.

Huang Yu sighed in relief. The successful transformation of the Purple Extreme Sword into an Earth-grade weapon greatly encouraged him. With the Thunder Dragon Technique advancing to the third level, he was just one step away from his goal. The final wave of the thunder tribulation would definitely be even more terrifying and powerful.

Thinking about how he almost couldn't withstand it earlier, Huang Yu was truly worried.

"Lulu, can we withstand the final wave of the thunder tribulation?"

"Master, why don't you trust Lulu? When have I ever exaggerated?" Lulu said, dissatisfied.

"That's not what I mean, I'm just worried."

"Is Master afraid?"

"Afraid? The word 'afraid' is not in my dictionary."

...

The final wave of the thunder tribulation was delayed, and the sky became even darker, putting the entire Seven Waters City under extreme pressure.

"Heavens, who is undergoing the tribulation? Is that the legendary Six-Nine Heavenly Tribulation?"

"That's the direction of the Divine Stone Pavilion."

"How is that possible? Could it be that the old man Gu Tian is actually a peak Yin-Yang Realm expert?" In the Liu family, Liu Guangming had already seen the thunder tribulation, initially thinking it was just a regular thunder tribulation, but now realized it was a Six-Nine Heavenly Tribulation. This meant that the opponent was at least a Life-Death Realm expert. Thunder tribulations in the Thunder Tribulation Realm had only nine waves, while those in the Yin-Yang Realm had a maximum of twenty-seven waves. Only the Life-Death Realm had the Six-Nine Heavenly Tribulation.

Thinking of this, Liu Guangming broke out in a cold sweat. Fortunately, he hadn't clashed with the old man Gu Tian. If he had directly rushed into the Divine Stone Pavilion to capture someone, he probably wouldn't have known how he died. A peak Yin-Yang Realm expert was not to be trifled with. Even in the entire Central Yuan Sword Sect, there were only a dozen or so Yin-Yang Realm experts.

"Damn it." Liu Guangming was furious. Thinking that Gu Tian was a peak Yin-Yang Realm expert made him extremely depressed. If Huang Yu was really favored by Gu Tian's daughter, Gu Xin, as rumored, then any move against Huang Yu would be blocked by Gu Tian. If anything happened to him, with Gu Xin's character, the entire Liu family might not be able to live in peace, and might even be destroyed.

One must understand how terrifying a peak Yin-Yang Realm expert is.

"Six-Nine Heavenly Tribulation, I hope you fail." Liu Guangming cursed in his heart, resentfully.

He knew that if Gu Tian passed the heavenly tribulation, it would mean his cultivation advanced further, becoming a Life-Death Realm expert, which was even more terrifying. In the entire Central Yuan Sword Sect, there were only two Life-Death Realm experts: the Sect Master, Central Yuan Invincible, and the Grand Elder, Ouyang Yeshuo. Both were Life-Death Realm experts.

But the Central Yuan Sword Sect wouldn't oppose a Life-Death Realm expert for his sake. Therefore, it was unrealistic to deal with Huang Yu now, and there was no chance of obtaining the thousand-year jade heart from him.

At this moment, those who didn't want Gu Tian to pass the heavenly tribulation weren't just Liu Guangming, but also Chen Hongqiao and Nian Shangcheng.

Chen Hongqiao hated Huang Yu to the bone, so after Huang Yu appeared in Seven Waters City, he had people keep an eye on him.

As for Nian Shangcheng, it goes without saying. Huang Yu had humiliated him, and his hatred for Huang Yu was no less than that of Chen Hongqiao and Liu Guangming.

"Who would have thought that the old man Gu was hiding so deeply." In the depths of the Seven Waters City Lord's residence, an old man opened his eyes, looking in the direction of the Divine Stone Pavilion, a sharp light flashing in his eyes.

"He has broken through, finally broken through." In the west, in a bamboo garden, a white-robed scholar held a jade cup, looking in the direction of the Divine Stone Pavilion, muttering to himself.

...

...

"It's coming, finally coming." Looking at the rolling thunderclouds in the sky, Huang Yu was surprisingly calm.

"Master, this is the time. Charge up, into the tribulation clouds." Lulu suddenly spoke.

"What? Lulu, are you joking?" Huang Yu was startled, "Charge into the tribulation clouds? Are you sure you're not mistaken?"

"Hurry up, Master, or it will be too late when the heavenly thunder descends." Lulu, seeing Huang Yu still asking for reasons, shouted anxiously.

"Alright." Huang Yu had no choice but to nod.

Gathering all his strength, he pushed off with his feet, rising from the ground and instantly charging into the clouds. His long sword, along with his entire body, transformed into a sharp flying dagger, completely entering the tribulation clouds.

The moment he entered the tribulation clouds, Huang Yu felt as if he had entered a world of lightning. Inside were all terrifying, pure lightning powers. These powers, carrying terrifying destructive forces, continuously ravaged and destroyed his body, which had just been repaired.

His internal meridians were breaking inch by inch.

"Thunder Dragon Technique, continue refining." Huang Yu, despite the intense pain, gritted his teeth and crazily运转 the Thunder Dragon Technique, trying to absorb these lightning powers for his own use.

"Master, the thousand-year jade heart, quickly, use the thousand-year jade heart." At this moment, Lulu's voice sounded in his ear again.

Huang Yu didn't hesitate and took out the thousand-year jade heart.

"Master, place the thousand-year jade heart in your dantian."

Huang Yu followed her instructions and placed the thousand-year jade heart in his dantian.

Surprisingly, the moment the thousand-year jade heart was placed in the dantian, it emitted a brilliant light, starting to absorb the lightning powers and continuously converting them, transferring them into Huang Yu's dantian. It began to repair and transform his dantian. Then, the three thunder dragons he had cultivated were also absorbed into the thousand-year jade heart.

Seeing this, Huang Yu was greatly alarmed. If the three thunder dragons were refined, wouldn't it mean he would be crippled in the Thunder Dragon Technique?

However, Huang Yu soon realized that his worries were unnecessary. The three thunder dragons, after being absorbed into the thousand-year jade heart, were quickly released, and they became even purer. Although they were smaller, they were easier to control and more powerful.

The released thunder dragons absorbed and refined the lightning powers much faster, almost twice as fast as before.

Suddenly, the thousand-year jade heart emitted a brilliant light again, began to swell, and then exploded like a bomb.

Yes, the thousand-year jade heart exploded in Huang Yu's dantian.

"Damn, how could this happen?" Huang Yu was terrified, his soul almost fleeing. How could this be? The thousand-year jade heart exploding in his dantian would destroy his dantian. The thousand-year jade heart was incredibly powerful, containing energy far beyond ordinary spirit stones. Although it was only a thousand years old, compared to the ten-thousand-year jade heart, it was far inferior, but the key was that his dantian was so fragile and small. Now, with the thousand-year jade heart exploding in his dantian, he was definitely finished.

The explosion caused intense pain, almost making Huang Yu faint.

"Master, hold on, hold on, you must hold on."

"Ah..."

Hearing this, Huang Yu gritted his teeth and resisted the intense pain. At this moment, the Purple Extreme Sword also moved, shrinking and instantly entering his dantian.

Damn, what's happening? Is this really the end for me?

At this moment, the Purple Extreme Sword, which was out of control, also joined in.

"Finished." This was Huang Yu's thought at the moment.

But to his surprise, after the Purple Extreme Sword entered his dantian, it began to gather the lightning powers. The energy released by the explosion of the thousand-year jade heart was orderly and continuously integrated into his dantian, forming a new, much stronger and wider dantian. If the previous dantian was a small pond, the new dantian was a large lake, the difference was significant.

Moreover, almost half of the dantian was filled with purple lightning power, and four thunder dragons were roaming in the purple sea.

"This... this... Lulu, what's happening?" Although his internal meridians were not yet repaired and the intense pain in his body was still the same, the changes in his dantian amazed Huang Yu. This was like a transformation from hell to heaven, too dramatic. Regardless, Huang Yu knew that the changes in his dantian were definitely good.
