My Multisystem In Isekai

This brought him a sigh of relief. They weren't sure what would happen when he mixed his blood with black gunk, but they knew it wouldn't be easy.

[Congratulations for successfully fusing your blood with the mysterious ooze.]

Zavier was quite weak at the moment due to blood loss, but reality didn't let him even a moment of rest.

The falling rocks above him continued to dribble like rain, the ground began to tremble, and the walls around him began to tremble.

"It must be the dark stuff that kept the cracks from collapsing previously. Furthermore, these were caused by the prior explosion. We must leave right away!" Hansa's voice was franker than usual.

A massive boulder fell from the roof and landed on the location where they were standing. It shattered a massive hole in it. Fortunately, none of them had been hit, but the entire area was still trembling with each passing second.

"We have to get going!" she exclaimed emphatically.

A loud blast interrupted Zavier's ability to respond effectively.

With a thud, the cave they were in crumbled!

A significant part of a hillside crumbled could be seen from a high altitude.

The trees in the area were all uprooted and damaged. Trees and stones began to fall from the slope. All of the rubble finally slid downhill, forming a massive ditch that stretched for miles.

Within seconds, a massive landslide had engulfed the region. The landslide was so powerful that the earth shook violently as it was dragged down into a pit.

"Rocks were constantly sliding down the hill, and trees were being crushed beneath their weight as well. Everything appeared to go slowly.

The earthquake grew stronger and more powerful as the rubble pile went downward. The landslide reached its apex in seconds, driving everything it touched backwards until there was nothing left standing.

After the landslide stopped moving and all sounds stopped, a faint sound of fractures could be heard.

A massive pile of debris was removed from below with a thud.

Two figures came from beneath the ground.

It turned out that Zavier arrived just in time to control the black ooze and save them from being crushed to death by boulders.

"At long last, we're saved." After a rough time, Hansa exclaimed, "Rebirth!"

Her comfort was short-lived, however, when she noticed the plight of her surroundings. "What in the world happened here?! This place has been destroyed, and the ground is littered with rubble!!"

That sentence was followed by a thunderous bang. A tree had been pulled out of the ground and had fallen to the side, blocking Zavier's path.

"It appears to have been caused by the recent mountain collapse, but I didn't expect it to be so broad." Zavier conducted an examination.

Hansa returned her gaze to the black sludge beneath her feet and mused, "What an oddity! Didn't it just attempt to murder us? Why would it want to help us?"

"Because I have control over it now."

When Hansa heard this, she turned to Zavier and asked him, "What exactly do you mean? Can you really keep the black ooze under control now?"

Zavier solemnly nodded his head. "Indeed. I've mastered this black goo." His tone was not arrogant. It was accurate and confident.

"How do you go about it? Incredible!"

Hansa was taken aback, but she quickly recognized that this was probably due to his hereditary power. It was also banned to inquire about each family's hereditary power.

But Zavier was unconcerned, explaining plainly, "I fused it using my genetic strength."

Hansa, on the other hand, was startled that he said it so directly. When she realized that four members of their group were absent, she queried shyly, "The other four members of your group...?"

"It devoured them." Zavier pointed to the remaining black ooze on the ground.

Hansa took a deep breath, followed by a sad, self-conscious look "I apologize. I was too feeble to be of any assistance to you."

Zavier made a wave "No. I made the proposal for further investigation. I should shoulder the majority of the blame."

Hansa had not expected such a significant loss of life, but she had seen casualties in previous trips, so she did not appear overwhelmed. "What are you going to do with it?" she questioned when she had calmed down a little. He indicated the unidentified black material.

Zavier stroked his chin and wondered, 'How did I manage to fuse those dark chemicals so quickly?'

[This is most likely because of the spiritual strength in the Divine Tree branch.]

"What exactly do you mean?"

[For unknown reasons, the host's blood could not directly fuse the black substances, but the two fused properly by using the spiritual power in the Divine Tree branch as a conduit.

"Do you mean my blood, the dark material, and the spiritual power in the Divine Tree have now merged?"

[Almost certainly.]

Zavier swiftly made an educated guess. Then he pulled out the branch and told the black stuff to eat as much of it as it could.

The command was received by the black matter beneath the ground, and it began to wrap around the branch, but for some reason, it was never able to entirely swallow it. So, the dark substance kept trying to swallow the sacred tree branch by making itself smaller and smaller.

During this procedure, Zavier appeared to form a familiar bond with the branch. He appeared to believe that the branch was his arm and that he could drive it at will.

At the same time, the dark substance continued to compress its volume and adhere to the branch's surface like glue. Zavier could sense that they were also undergoing a particular fusion throughout this process.

After a few seconds, many black things and sacred tree branches came together to form a black rod.

The black rod was light, much like a regular wooden stick, which surprised Zavier.

"It's incredible that such a vast volume squeezed into such a little one retains its mass!"

He said to Hansa, "Let's go back and turn in the mission," as he put the black rod around his waist.

It was time to say farewell when they both arrived at the exchange to complete the filing process.

"Will we have another chance to work together?" Hansa asked, hesitantly.

"Without a doubt! I still require you to create a potion for me." Zavier answered positively.

Hansa nodded and smiled softly.

"How can we contact you if necessary?"

Zavier paused for a bit before saying, "Humm..."

Because he had chosen to act alone at first, he wasn't totally ready for this.

"You can contact me through it," Hansa said, removing a green pendant linked to her wrist and slipping it into his hand.

"No, it's over the top."

In this isekai, magical communication jewelry that worked at the right time was especially expensive, and even though he was a noble, he did not have one.

Hansa jumped away like a rabbit before he could return it to her.

"Don't forget to contact me!"

Zavier soon lost sight of the girl's figure.

He groaned and replaced the chain around his neck.

————————————————————————————-

When Zavier returned to Caesar University, he discovered from the clone that stayed there that his Uncle Val was relocating their family to Caesar, the capital city.

This surprised him a little, but he quickly realized it was because of the secret behind him. If Val's intention was to protect him, it made sense.

'Wait! If that's the case, will Valarie join us?'

The door to his room was suddenly pulled open while he stood on the bedroom floor mulling this topic.

When a woman with an hourglass shape saw Zavier, he used a judo move to put his head between two big breasts.

"I heard you defeated this freshmen's dark horse. When did you become so skilled?"

The strangulation had almost taken Zavier's breath away. "Oh my God, I'm literally dying."

Valarie muttered as she let go of her hand "It's a pity! I'm not able to tease you as much as I used to."

"Did Uncle truly send you here to protect me and not to murder me?" Zavier coughed a few times.

Valarie planned to keep joking with him, but she was pulled to the hazy aura that had been disclosed about him. "You upgraded to B rank?" she asked, surprised.

"It was a few days ago," Zavier said happily.

Then Valarie's demeanor became solemn, as if she was deliberating over something.

"What's the matter? Isn't that a good thing?" Zavier was perplexed by her expression.

"Of course, it's a good thing if it's for other people," Valarie remarked, "but it could not be for you. Do you recall what I stated previously about my deliberate taunting of you?"

"I empathize," Zavier smirkded bitterly.

"It's mostly Val's plan." One motivation was to attract possible assassins. If I continue to act too friendly or near to you, the enemy in the shadows will not be able to strike as easily, increasing our workload. Because the cost of constantly being on the defensive is significantly more than the cost of creating a trap once."

"That makes sense," Zavier massaged his chin.

"And one of the reasons I don't need to pretend to act that way longer is that you have the basic ability to defend yourself," Valarie continued. Plus, I've moved from being a hidden pawn to an open pawn on the board, which has raised the number and rank of your dark guardians."

"Why?" interjected Zavier.

"Because the enemy has taken more aggressive steps," Valarie stated solemnly.

Zavier's heart skipped a beat, and he realized, "Because I've grown stronger?"
