Hunting Tartarus for 100,000 years

I do not know how long it has been.

A heavy rain fell on the desolate planet, and the heavy rain hit Ultraman Zeta, making crackling sounds.

"Little Tias!"

With a scream, Ultraman Zeta woke up from his coma.

He looked around trying to find any trace of Tias, but he was the only one left on this land in the heavy rain.

He punched the ground angrily, splashing countless gravel and water. The gravel scratched his face without him noticing.

"Little Zeta, don't be sad." The voice in Zeta's mind suddenly sounded.

Zeta's voice was choked, "Sister Tias...what should I do?"

"Don't be sad anymore. It's not your fault that little Tias was kidnapped."

Zeta suddenly shouted, "No! This is my fault! I handed her over to Tartarus with my own hands! I thought that this way she could return to her original life, and I wouldn't keep distorting history and going in the wrong direction."

"But... Dark Mephisto suddenly erupted. No one could have predicted that. Zeta-chan, you can't take all the blame on yourself like this."

Zeta murmured, "Dark Mephisto... Yes! There's also Dark Mephisto. That's my fault too! If I hadn't underestimated the enemy and caused Dark Mephisto to mark Tias, little Tias wouldn't have been infected by the aura of dark evolution!"

The voice in his mind suddenly fell silent. Heavy rain pounded on Ultraman Zeta, and his lonely figure lowered his head.

After a while, the voice in my head spoke again: "That's enough time complaining about myself!"

"Sister Tias..."

"So what are you going to do now?"

"I……"

"Are you going to sit here and feel sorry for yourself?"

"I……"

"Zeta, will you abandon Tias and let her fend for herself?"

"I won't!"

"Zeta, will you let Tartarus sacrifice the life of Little Tias for his so-called great cause?"

"I won't!"

"Xiao Zeta, will you let Tias go down the dark path because of the influence of you two outsiders?"

"I can't!" Ultraman Zeta shouted loudly.

In the heavy rain, Zeta's diamond-like eyes suddenly sparkled. He said, "I have always been reluctant to leave little Tias. Although I know it is wrong to be with her, I still can't help myself. Even though I have made up my mind to be with little Tias forever, I can't help but waver. But now, although I don't know what choice I will make in the future, at least before making that choice, I will make up for my mistakes. I want to go and save Tias, now!"

Ultraman Zeta stood up, "But now...how can I find Tartarus and Little Tias?"

He pondered for a long time, and suddenly remembered the scene when Tartarus arrived and jumped into the river because he could not find the trace of Dark Mephistopheles.

"That's right! There must still be a lingering aura of Dark Mephistopheles in there!"

Ultraman Zeta flew to the big river. Heavy rain was pouring down and the river was turbulent. Zeta jumped in without hesitation.

In the river, Zeta sank to the bottom, relying on the faint light to follow the breath of dark evolution and continue to move forward.

Finally he arrived at his destination in front of a messy ruins.

There are several broken stone pillars in front of us. In the center of the pillars is an ancient stone platform with complex and heavy runes engraved on it. In the center of the runes is a big pit, which seems to be the place used to seal Dark Mephistopheles.

There was also a slowly rotating black airflow in the big pit that seemed to be about to dissipate.

"It's the aura of dark evolution."

Ultraman Zeta stretched out his hand forward, trying to collect the airflow formed by the dark evolutionary aura, but as Zeta's hand moved, the airflow actually dodged him.

Zeta was puzzled and reached out to grab the airflow with both hands again, but found that no matter how he moved, the airflow always avoided his movements.

"How could this happen..." Zeta was confused.

"This is the breath of dark evolution, which can only be used by dark giants. To a messenger of light like you, it is like water and fire that cannot mix." In Zeta's mind, the consciousness formed by Absolut particles, which Zeta called "Sister Tias", said.

Zeta said: "What should we do? This is the only way I can think of to find them..."

"Xiao Zeta, if you want to use it, I'm afraid you can only use your own color timer to accept it, abandon the light and become a dark giant..."

"Become... a dark giant?" Zeta nodded after hearing this, "I understand."

Zeta held both hands together next to his Z-shaped color timer, and the color timer shone brightly.

The dark evolving airflow inside the pit suddenly rolled and boiled, as if it had seen some prey, but it still stayed where it was and dared not move.

"Xiao Zeta, have you thought it through?"

"There is nothing to hesitate about, Sister Tias. Even if I am trapped in darkness, I will never return to darkness. What's more, little Tias needs me." Zeta said firmly.

He reached out and touched the dark evolutionary aura.

The moment Zeta touched the air flow, the air flow seemed to be freed from some restrictions, and instantly surged up along Zeta's arm towards the wide-open colorful timer.

Zeta's color timer was gradually permeated by the aura of dark evolution, and even his diamond-like pupils gradually became turbid.

But at this moment, in Zeta's mind, the Tias particle sighed, "Actually, there is another way..."

At the moment the voice was heard, the dark aura that had melted into Zeta's colored timer and eyes gradually disappeared.

"What's going on?" Zeta was puzzled.

In his perception, the dark evolutionary energy that entered his body actually all gathered in his head.

"This is……"

Those dark evolutionary auras actually followed Zeta's energy veins into the deepest part of his energy core and merged with the last remaining Absolute particle in his body, that is, his "Sister Tias"!

"Sister Tias...what are you doing?" Zeta asked in confusion.

As the dark evolutionary aura and Absolut particles continued to merge, the dark power continued to expand in Zeta's body, but it had nothing to do with his own power.

"Sister Tias!"

Zeta did not transform into the Dark Titan.

Instead, within his body, a Dark Tias appeared again!

The dark Tias in his body said: "Don't worry, I'm fine..."

Zeta sighed, "Sister Tias, it would be great if you were really my sister."

"Why... am I not?"

Zeta was stunned, then smiled.

"Of course you are, my sister Tias."
