Rebirth

Leviathan opens up the door with a swing of his tail and then began moving inside towards the next room that was guarded by the four statutes. As they made it inside, both Tang Wulin and Leviathan eyes widen when they saw a golden spring inside of the room.

"A spring?."Questioned Zeref as he appeared next to both of them.

Tang Wulin said nothing as he began furrowing his brows, while Leviathan titled its head and moved its eyes all around the room. As they were looking around, a spectral sign appeared before them with some words.

"Pool of Rebirth." Said Zeref out loud as he read the words on the sign. Then more words began appearing on the signs causing Zeref eyes to widen even more.

"This is the reward to the one that was able to reach here and beat the Four Devas that guards this room. Step into the blood of the gods and through your effort and become a new existence." Said Zeref as he read the other writings.

"That sounds pretty vague." Said Sleipnir as she appeared next to them and Zeref nodded his head with her.

"What exactly is going to be rebirth?" Questioned Tang Wulin but the spectral board simply begins to fade, since its job was done.

The people in the room were both puzzled and curious about the gains of the pool. As even though it was very vague, the title and wording of was something that couldn't be look over.

"Why can't they just be straightforward?" Questioned Tang Wulin with a sigh and he then got off Leviathan body.

Zeref only let out a small chuckle as he glances at Tang Wulin getting into a meditative position and beginning to recover to optimal condition. He nodded his head at this, as jumping into the pool without being prepared and not in the best condition was very stupid.

'Not only that but this place doesn't seem like to type to give free rewards.' Thought Zeref.

After ten minutes Tang Wulin opened his eyes and got up to stretch his body out. He could feel ache and soreness around his body that was healing at a rapid pace, thanks to the terrifying might of his dragon body.

"That attack really damaged you that badly." Said Zeref as he noted Tang Wulin movements.

"It really was drawing every wisp of strength from my body down to the cells."Mutter Tang Wulin as he twisted his back.

"Hmm, what are you going to name the attack? As I doubt it will be the last time, you will do it." Said Zeref as he knew the consequences of the attack wouldn't stop Acnologia.

"Endless Spear." Said Tang Wulin after a while, causing Zeref to nod his head.

"Not a bad name." Said Sleipnir with a smile and Leviathan went up to nudge Tang Wulin.

"Well, time to go." Said Tang Wulin as he began heading toward the golden pool.

Zeref and Sleipnir said nothing as they didn't sense anything was amiss. Sleipnir detects no energy of the aura of death and strangely only a boundless amount of life energy flowing abundantly through the pool.

While Tang Wulin instincts weren't screaming out to him nor were his Asura bloodline giving off a warning. Considering his instincts has never been wrong before and his Asura intent had always warned him about a bad premonition.

He made sure to strip off his clothing first and then dip himself into the golden pool.

As he began sinking below the sparkling water, he could feel the extraordinary warmth seeping inside his body and his cells. All the pores of his body were relaxing and expanding.

A strange irresistibly intoxicating fragrance began to spread out around the room. Leviathan eyes to widen and it started to gain the desire to jump into the pool with Tang Wulin.

He tried to will himself to calm down but after a while, he knew it was a fruitless effort and he dismisses himself. As the golden essence was flowing inside of Tang Wulin, ripples appeared above as a great change began to take place.

The golden liquid surged and then started to condense around Tang Wulin. Stream and specs of glittering light curled around as if they were moths to the flames. The specs of light flowed around his endlessness until the golden pool turned into a cocoon that encased Tang Wulin inside.

Something strange begins to happen inside of Tang Wulin body that caused sweat to go down his forehead even while he was encased in the cocoon. Multiple beasts roars rang out of his body as ethereal figures began to appear above Tang Wulin.

"Amazing Dad!"

"Nice Work human!"

Leviathan, Taotie, Sarial, and Kirin stood above the golden cocoon with boundless amount energy rolling off them. Zeref and Sleipnir were seeing this as they were watching over Tang Wulin in case something went bad.

"They're getting stronger as if their age is increasing. Could it be that their age is actually increasing?"Questioned Sleipnir with her eyes widening.

"Could it be the pool isn't strictly for Tang Wulin but the powers inside of him?" Questioned Zeref but Sleipnir only continued to stare forward while solely paying attention to the phenomenon.

Tang Wulin himself could feel his four spirits were greedily absorbing all of the golden essences that flowed through his body, and it was increasing their age. This was something that shocked even him as it was almost impossible from what he knew to raise a spirit ring age after it has been absorbed.

While it was possible through a spirit soul, that required a large amount of payment towards the Spirit Pagoda. Also, four of his spirit rings weren't even spirit souls, so not all of his rings would have been upgraded.

So the fact this pool was able to fully increase their strength and age was in itself a miracle. Yet that wasn't the end as Tang Wulin felt another pulse through his body and to his shock it came from his back.

A blazing amount of heat began spreading through his back as he could feel something trying to force itself outside of his lower back. Unbeknownst to Tang Wulin, his four wings were erupted out with the top being his light wings and his bottom one having streaks of gold through it.

Zeref and Sleipnir glance at each other, as underneath both of the wings specks of light started to swirl around the back. Then two wings began to grow out of Tang Wulin lower back to the height of the other wings and shined as bright as a star.

Zeref and Sleipnir eyes widen at the wings.

"Don't tell me it's actually strengthening his soul's bones too!" Shouted Sleipnir in distinct shock.

Tang Wulin spirit bones and spirits were frantically devouring it all. All of the essences were being pulled towards his back and his rings.

It was then Kirin that was above the cocoon ring started to tremble and then to the shock of Sleipnir, started to turn red.

It wasn't only Kirin ring that was changing as Taotie and Sarial ring began to turn from purple to black. It was a sign of them breaking through the ten thousand year age bottleneck and the hundred thousand year for Kirin.

A spirit ring undergoes various amounts of color from white-yellow-purple-black and to red with red meaning the spirit has broken through the hundred thousand-years bottleneck.

It was then an intense pain began to reverberate through Tang Wulin body. Tang Wulin was gritting his teeth as his three hearts began to pump rapidly with his mind trembling from the pain that was reverberating through his soul and bones.

The pain was far less than when he did the Spirit Metamorphosis. But unlike the metamorphosis, he felt like his soul was burning and his mind was being torn apart. Blood was leaking from his nose but he still uses his terrifying amount of willpower to hold on. He knew if he blanks out now, he wouldn't be able to absorb all of the golden pool.

"It's breaking." Said Sleipnir as her eyes were watching the life force and condition of Tang Wulin.

"What do you mean?"Questioned Zeref but Sleipnir said nothing as she narrowed her eyes.

The sphere that was incasing Tang Wulin began to slowly seep into his body. He could feel his whole being purify and cleanse by the second. After a while, the sphere was no longer visible as Tang Wulin was able to fully absorbed it. It was then his eyes open up and then he climbs out of the empty pool.

Zeref and Sleipnir let out a sigh of relief as they saw Tang Wulin was okay, while he was putting on his clothing. Subsequently, Tang Wulin was inspecting his body before he summons all of his spirit rings to look at them.

Black, Black, Black, Red, Multi-Colored and Orange-Gold appeared prominently behind Tang Wulin.

The aura they gave off would have even caused Titel Douluos to tremble and instantly be on guard from how terrifying it was.

"So they really increased in age, and it seems by a lot."Said Zeref causing Tang Wulin to nod his head and he began telling them their age.

Leviathan is over 43,000, Taotie is above 35,000, Sarial is over 39,000 and Kirin is over a hundred thousand years. Sleipnir and Zeref eyes widen at the terrifying amount that the spirits aged were able to increase by.

The process of the spirit rings age increasing at higher-stages become harder and harder the older they are. Compared to lower levels, getting sixty thousand years to hundreds of thousands of years would cost a fortune with a lot of time and even some more.

Not only that but that was only for one spirit and not three others. The fact that Tang Wulin four spirits increased their cultivation by over thirty thousand years is just a miracle.

"My Light Wings became a fifty thousand spirit bones."Said Tang Wulin as six wings erupted from his back and flap out.

All six wings swayed gracefully with a fierce and dazzling aura. Zeref begins inspecting the aura, while Sleipnir was inspecting the rings.

"Did the bones gain any new abilities?" Questioned Zeref causing Tang Wulin to nod his head as he began explaining.

The Light Wings automatic defense system became even stronger as they are able to react to things that are even three times faster than him. They have also been influenced by his Asura bloodline causing them to gain the same terrifying amount of perception against danger.

It also gained the ability to even block mental attacks and even spatial attacks. This surprised Zeref immensely as this gives Acnologia an extra defense against spatial attacks that can attack his internal organs.

"And the final ability is a forcefield that lasts for ten seconds but it produces a defense that is about twice as strong as my own body."Said Tang Wulin.

Zeref and Sleipnir nodded their head as the harvest this time wasn't anyway bad. In fact, with this, all of Tang Wulin abilities have increased by tenfold. As with the increased age of his spirit rings, their abilities have increased.

"But why didn't your other spirit rings or bones get stronger too?" Questioned Zeref.

"It may be because the absorption wasn't enough for any notable change." Said Sleipnir.

"I guess you are right. I forgot that three of your rings and most of your spirit bones are at least one million years old or more."Said Zeref.

"Indeed, something that would cause the whole world to erupt in disbelief and madness."Said Sleipnir with a giggle.

The fact that Tang Wulin has rings that are over a hundred thousand years by just his fourth ring was something unbelievable. But the fact his other two were one million? Sleipnir couldn't imagine the type of reaction that would be garner from this and that wasn't even talking about Wulin spirit bones.

As not only does he have almost a full set of them but most of them were one million years old from the Dragon Kings and Sleipnir herself.

Tang Wulin body itself is a literal treasure. She wouldn't be surprised if this caused even most honorable people to be blinded by greed and wanted to find out all of his secrets.

"I guess that old man really helped us out."Said Zeref

"I guess."Said Tang Wulin with a nod of his head.

"Well anyway, we should leave this room and meet everyone on the extra floor." Said Sleipnir.

They all nodded their head and turned to the enormous doors ahead.
