Wang Jingze Theory

As the Flood Dragon began to go berserk, Ling Qingping moved to a safe distance where she wouldn't be affected. Meanwhile, Lu Jiuyuan stood steadily on the Flood Dragon's head, repeatedly hacking at it with the Qingfeng Sword.

"Damn human, get off me!"

The Flood Dragon roared in anger, but its claws were too short to reach Lu Jiuyuan. It could only try to shake him off by thrashing its body. Finally, it succeeded.

However, it was Lu Jiuyuan's intention. He realized it was difficult to maneuver on the Flood Dragon's head, so he decided to jump down to finish the beast with a single sword strike. 'It's so big, it should last me a long time,' he thought.

"Human, die!"

Seeing Lu Jiuyuan flung away, the Flood Dragon immediately charged at him. Lu Jiuyuan calmly gripped the Qingfeng Sword, a sharp aura emanating from him.

At this moment, the Flood Dragon sensed something. Its eyes widened, and it stopped dead in its tracks. It felt a deathly aura from a cultivator at the peak of Qi Refining.

"What? Impossible!"

The Flood Dragon exclaimed in disbelief. It then regrouped and prepared to charge at Lu Jiuyuan again. By now, Lu Jiuyuan had gathered his strength. He suddenly drew the Qingfeng Sword, unleashing a terrifying sword energy.

"Clear Wind Slash!"

Lu Jiuyuan said softly. However, the sword energy was anything but calm like a gentle breeze; it was like a raging storm, carrying the power to destroy everything.

'I can't take this head-on, or I'll die,' the Flood Dragon thought without hesitation. It then said in panic, "Stop, human!"

The Clear Wind Slash dissipated about three meters away from the Flood Dragon, narrowly missing it.

"Oh? Did you want to say something?"

Lu Jiuyuan asked calmly. He could still unleash the Clear Wind Slash a few more times, so he wasn't afraid of whatever else the Flood Dragon could do.

"Hoo, I am willing to become your servant! Just spare my life!"

The Flood Dragon said earnestly. Lu Jiuyuan frowned slightly. It wasn't that he didn't want to take the Flood Dragon as a subordinate, but he wasn't sure if he could bring it out of the Secret Realm.

Seemingly sensing Lu Jiuyuan's concern, the Flood Dragon quickly added, "My lord need not worry. Once we establish a spirit beast contract, I will be considered your possession. When the Secret Realm closes, I will be teleported out with you."

Hearing the Flood Dragon's words, Lu Jiuyuan pondered. 'Having a True Dragon as a mount does sound pretty good, doesn't it?' he thought. 'Others travel by flying artifacts, but I'll be riding a True Dragon. That'll really boost my prestige.'

With that thought, Lu Jiuyuan extended his hand. "Hand over your true spirit!"

A flicker of struggle crossed the Flood Dragon's face. However, remembering that it couldn't break through to a higher realm within the Secret Realm and transform into a True Dragon, it reluctantly handed over a part of its true spirit.

The true spirit is an extremely precious thing for any cultivator. By controlling even a part of another person's true spirit, one gains the power of life and death over them, no matter how powerful they are.

"Human, you know how to establish a spirit beast contract, right?"

The Flood Dragon looked at Lu Jiuyuan with some doubt. Lu Jiuyuan let out a soft scoff.

"A mere spirit beast contract, what difficulty is there? Watch closely."

Lu Jiuyuan confidently formed hand seals. Instantly, a profound power emanated from him. The Flood Dragon felt something and looked surprised.

"This is... a Heavenly Dao Contract!"

Normally, a spirit beast contract could ensure the spirit beast's loyalty. However, if the spirit beast's cultivation level was two major realms higher than the master's, the contract would automatically become void.

But the Heavenly Dao Contract was different. Once established, even a cultivator at the Qi Refining Stage could control a spirit beast at the Immortal King Stage.

"Damn it, stop!"

The Flood Dragon roared in anger. Its original plan was to break through to the Golden Core Stage immediately after leaving the Secret Realm with Lu Jiuyuan. At that point, its cultivation would be two major realms higher, and the spirit beast contract would be automatically nullified.

However, it never expected Lu Jiuyuan to know how to establish a Heavenly Dao Contract. Although it was fast, Lu Jiuyuan was even faster. Before the Flood Dragon could react, Lu Jiuyuan had successfully formed the contract with it.

"Alright, from this moment on, you are my spirit beast."

Lu Jiuyuan said with satisfaction, feeling a subtle, inexplicable connection between himself and the Flood Dragon. The Flood Dragon stood stunned.

As a being on the verge of transforming into a True Dragon, it could sense things others couldn't. After signing the Heavenly Dao Contract with Lu Jiuyuan, it felt the immense fortune emanating from him, at least a hundred times more potent than that of ordinary people.

The thick fortune from Lu Jiuyuan, amplified by the Heavenly Dao Contract, completely dissolved the bloodline obstruction that was preventing its transformation into a True Dragon.

Simultaneously, the sky of the entire Secret Realm turned dark.

"This... a Supreme Treasure is about to be born!"

Countless cultivators at the Qi Refining Stage were shocked by this sight and rushed towards the location. They never imagined that this was merely a Flood Dragon transforming into a True Dragon.

"Go, go become a True Dragon. Otherwise, I'll stew you!"

Lu Jiuyuan said to the Flood Dragon with a smile. The murderous grin made the Flood Dragon's backside clench, and it immediately flew out of the cave.

After the Flood Dragon left, Lu Jiuyuan looked at Ling Qingping with a grave expression.

"This place will likely be discovered by others soon. Let's absorb the Glazed Treasure Liquid as quickly as possible."

Ling Qingping knew this as well. They didn't have time to waste and immediately jumped into the pool of Glazed Treasure Liquid. As their bodies were completely enveloped by the liquid, they felt an extremely pure energy improving their innate talents.

The most significant change was in Ling Qingping. Since she started at the Yellow Grade, the Glazed Treasure Liquid helped her break through to the Profound Grade in just a few minutes. She hadn't stopped there and was still pushing towards higher levels.

As for Lu Jiuyuan, his innate talent was already at the Heaven Grade Peak. His current transformation would naturally lead to Immortal Grade talent, which required a much longer time.

Meanwhile, numerous cultivators were rushing towards this location, all wanting to compete for the emerging Supreme Treasure. However, they didn't realize that all they would face was a Flood Dragon transforming into a True Dragon.
