Chapter 219

After a long time.

Ao Luan looked up and said: "I believe you understand the importance of the Thunder Pool without me saying it. Besides the Supreme Dao's Eternal Thunder Pool and the Creation Dao's Myriad Transformation Thunder Pool, the only one left in the world is my Heavenly Dragon Sect's Great Thunder Origin Pool."

Yin Qi nodded.

Ao Luan continued: "I can hand over the construction blueprints for the Great Thunder Origin Pool with both hands, but you need to agree to three conditions."

Yin Qi said: "Speak."

Ao Luan held up her index finger and said: "The first thing is, I have a mortal enemy named the Demon God Ba.

He is a Divine Ape who has attained the Dao; not only has he passed six Thunder Tribulations, but he is also a Human Immortal.

Because of his demon body, even true Human Immortals of the human race are not as strong as him; he is extremely formidable.

If it weren't for the Heavenly Dragon Sect's array, I would not be his match at all.

I hope you can kill him for me."

Yin Qi nodded: "I can."

Ao Luan finally revealed a smile, then held up her middle finger and said: "The second thing is, I want you to escort me to the void beyond the heavens to find the Dragon Tomb, where there is a complete Heavenly Dragon heritage. Of course, we will split everything we find inside equally, except for the Heavenly Dragon heritage."

Yin Qi smiled: "That is even less of a problem."

Ao Luan held up her ring finger and continued: "Third, I want you to protect me as I pass the fifth Thunder Tribulation."

Yin Qi smiled slightly: "This matter is also simple."

"Good! Wait here, I will go and get the construction method for the Great Thunder Origin Pool."

Ao Luan nodded with a smile and turned to leave.

As for taking a Dao oath or something, she did not ask Yin Qi to do so.

Even the Supreme Dao's Heaven Origin Divine Pill could not compare to them.

If Yin Qi did not want to keep his promise, he could completely seize it by force; there was no need to say so much to her.

Since that was the case, why bother doing something unnecessary and making people unhappy?

Not long after, Ao Luan returned, holding a turtle shell in her hand, and said: "The construction method for the Great Thunder Origin Pool is recorded on this turtle shell."

Yin Qi took the turtle shell, injected a bit of magic power, and many ancient characters appeared on it, along with a huge diagram.

This diagram looked like a gas egg, neither round nor square, flickering with virtual and real light.

One could see countless talismans shining with light.

These ancient characters were naturally recognized by Yin Qi; they were annotations on refining the Great Thunder Origin Pool, including the materials, techniques, talismans, and so on needed for refining.

Refining the Great Thunder Origin Pool required a massive amount of heavenly materials and earthly treasures, and the main material was actually Red Refined Origin Copper, which was a very rare divine material, very hard to find even in the void turbulence.

If it were anyone else, they would likely be scratching their heads, but he had just obtained the Sky City.

"It seems I need to re-refine the Sky City!"

Red Refined Origin Copper was too hard to find; he could only re-refine the Sky City and extract the materials for building the Great Thunder Origin Pool from it.

Not only that, he also needed to optimize the refining method for the Great Thunder Origin Pool.

By integrating the Fengshen artifact-refining method, he could completely increase the performance of the Great Thunder Origin Pool by a large margin, thereby surpassing the Eternal Thunder Pool and the Myriad Transformation Thunder Pool in one fell swoop.

After a long time, Yin Qi memorized the construction blueprints for the Great Thunder Origin Pool.

He returned the turtle shell to Ao Luan and said: "Sect Master Ao, thank you. I wonder where the Demon God Ba is? I can go and kill him now. Also, when do you plan to cross the tribulation, and when will we go to the Dragon Tomb?"

Ao Luan said calmly: "It doesn't need to be that troublesome; as long as I prepare to cross the tribulation, he will definitely appear. In this Heavenly Dragon Sect, quite a few people have already secretly defected to him. As for going to the Dragon Tomb, we can only wait until I recover."

Yin Qi nodded and asked: "How do you plan to arrange it?"

Ao Luan said: "You stay here for now; this is my sleeping palace, and no one else is allowed in without my order. To avoid the Demon God Ba's suspicion, I may need half a month to lay out the plan."

Yin Qi nodded: "Good."

……

Yin Qi stayed in the side hall of the Heavenly Dragon Hall.

He sat cross-legged and communicated with the altar: "Altar, I want to use the Fengshen artifact-refining method to optimize the Great Thunder Origin Pool and minimize the difficulty of refining it. How much fortune is needed?"

A grand voice sounded: "Three zhang!"

"Three zhang, huh."

Although it was a bit much, Yin Qi still gritted his teeth and said: "Good, optimize it."

After this Great Thunder Origin Pool was optimized, it could be used not only in the Yang God world but also in the Fengshen world.

"As you wish!"

As the grand voice finished, the red fortune dropped instantly, from 12.5 zhang to 9.5 zhang.

At the same time, Yin Qi entered a mysterious state; he seemed to be personally experiencing the process of optimizing the Great Thunder Origin Pool using the Fengshen artifact-refining method.

After more than ten years of comprehension, having tried who knows how many methods, he finally succeeded.

I don't know how long it had been, but Yin Qi exited the mysterious state.

His eyes flashed with brilliance, and a smile appeared at the corner of his mouth.

After optimization, the Great Thunder Origin Pool, although its power increased threefold, had its construction difficulty greatly reduced.

Not only did it consume fewer materials, but it also consumed fewer divine materials.

Originally, to build the Great Thunder Origin Pool, even if the materials were sufficient, it would likely take several years.

But now.

As long as the materials were sufficient, it could be built in at most three months.

Yin Qi contacted the Bagua Daoren and had it head to the void beyond the heavens to search for the materials needed to build the Great Thunder Origin Pool.

………

Time passed like a white horse crossing a gap, and in the blink of an eye, seventeen days had passed.

After patient planning, Ao Luan finally spread the news that she was about to cross the tribulation, and then mysteriously left the Heavenly Dragon Sect, heading straight for the depths of Mang Mountain.

……

Deep in the mountains ten thousand miles away from the Heavenly Dragon Sect, the sky was covered with dark clouds, and thunder was rolling.

On a certain mountain peak.

Yin Qi said: "You can rest assured and cross the tribulation; I will hide nearby later."

Ao Luan bowed solemnly: "This time, I leave it to you."

Yin Qi nodded, then his figure disappeared, hiding in the void.

Ao Luan searched carefully, but she did not find Yin Qi's tracks.

She was secretly shocked in her heart, but she also felt relieved.

Ao Luan sat cross-legged, looking at the rolling thunderclouds, and suddenly closed her eyes; then, a mass of strong yang wind darted out from the top of her head, rushing straight into the high sky.

Rumble!

With Ao Luan's intrusion, the thunder layer became violent, rolling thunder vibrating, constantly shaking between the mountains.

Thunder rolled in the sky, and streaks of lightning coursed through the clouds.

It was not until more than an hour later that the thunder quieted down.

In other words, Ao Luan's tribulation had ended.

Yin Qi looked up at the sky and saw that in the rolling thunderclouds, thoughts like bright red roses were rolling constantly, suddenly darting out.

There were over forty thousand of these thoughts.

Each thought was bright red, a zhang in size, emitting a massive aura.

However, there were shocking cracks on these thoughts, and some seemed completely broken, their interiors shattered, barely sticking together.

It was very clear that although she had luckily passed the fifth Thunder Tribulation, Ao Luan had also reached the edge of death.

Ao Luan's thoughts rushed out of the clouds, wandering in the sky for a long time before falling like a broken kite, slanting, but never able to return to her body.

In her current state, let alone a Ghost Immortal, even a cultivator at the Possession stage could likely kill her.

"Caw! Caw!"

Just at this moment, an unpleasant, excited, strange cry sounded in the forest, like an old demon coming out of a cage.
