After that, Luo Zhen and his entourage took a luxury limousine that seemed to be specially arranged that month and returned to the high-end apartment located in the western area of the artificial island.

Along the way, Nagisa and Agulola also asked Luo Zhen how they planned to solve the problem of Astarutti's lifespan.

This question, in fact, is not difficult to say.

"If it is a more orthodox method, it is necessary to use magic and spells as the main means, supplemented by cultivation tanks and adjustment equipment, etc., to adjust the body of the artificial lifeform, and slowly make up for its missing vitality, then it will be fine."

This is a more modest way, the advantage is that it can be missing to make Astaruti better, and the disadvantage is that it is time-consuming and labor-intensive, which is quite troublesome.

"Of course, there are ways to be a little more evil."

Luo Zhen also said the same.

"As long as you absorb the life force you need from other individuals, you can also replenish your lifespan."

In the scope of Luo Zhen's knowledge, many magicians and spellcasters have used this evil method to gain a long lifespan.

There are even many people of this type, like the former Ashiya Michiman, who gave up their identity as a human and incarnated into an unknown existence in order to obtain a near-permanent life.

So, there are many ways to extend an individual's lifespan, but almost none of them are good.

Luo Zhen is ready to use a method that is not very good.

"I can offer my life force to Astaruti so that her problem can be solved."

Luo Zhen had such a plan.

This, of course, was strenuously opposed by Nagisa and Agulola.

"How... How so? Isn't that Yao-kun going to be dangerous...!? ”

"I... I don't think that's right! And irrational too! ”

Nagisa and Agulola spoke out excitedly against each other.

This made Luo Zhen smile bitterly and quickly explained.

"Don't worry, I'm not great enough to dedicate my life to the person I met for the first time, it's just that I'm different from ordinary people, there is a monster with infinite vitality in my body, as long as I use its vitality, it's foolproof."

Exactly.

Just like the beast in his blood, Luo Zhen can let the seal in his body directly pay for his vitality, and in the same way, Luo Zhen can also directly connect a path with Astaruti, through which Astaruti can absorb life force from the seal in Luo Zhen's body, and then he can not only make up for the defective lifespan, but also continue to use the artificial beast that coexists with him.

It's not that hard.

In the Chaldees, there have been records of observing the Holy Grail Wars in parallel worlds, and many of them have used this method to connect with other individuals in the outside world, and let the magic power consumed by the servants be paid for by beings other than the master.

The reason why the Chaldean Immortal Summoning System was able to pay for the mana required by the Servant of the Contract was built on the same theory.

Drawing on that theory and method, Luo Zhen was able to use the same method to connect the demons he summoned and the beasts he raised to the seals in his body, so that the seals could pay for magic and life force.

It's just that when you use magic and spells, you can't do it, the magic power consumed needs to be paid for by yourself, and you can't establish a path with the seal in your body, otherwise Luo Zhen doesn't need to unlock the seal at all, just use the magic power of the seal directly.

As for Astaruti's words, Luo Zhen can completely build a connection with him in a way similar to a contract, and then establish a pathway, so that Astaruti can absorb the vitality of the seal in his body.

Naturally, this is equivalent to holding Astaruti's lifeline in his hands, as long as Luo Zhen is willing, he can stop Astaruti's vital signs at any time, so if you don't entrust your life to Luo Zhen's enlightenment, it's better not to use this method.

"Anyway, I'll wait and see Sister Nayue first, and then I'll ask the child in person after she finishes protecting Astaruti, and see what she says, you don't have to worry about it."

Luo Zhen said this, so that the two girls finally felt at ease.

So, the group returned home smoothly.

It's just that after sending Nagisa and Agulola home, Rajin came out again.

The destination is the apartment located under his room.

And Luo Zhen had just come here when the door was opened.

"Is there anything you want me to do? Senior? ”

Xuecai, who also returned home just now, kept the posture of opening the door and looked at Luo Zhen suspiciously.

It seems that Yukina, who was monitoring Luo Zhen's every move with Shikishen, had already noticed that Luo Zhen was coming in the direction of his home, so he would open the door immediately.

"I'm just here to see."

Luo Zhen casually perfunctory, ignoring Xuecai's astonishment, and went directly into his home.

"Wait, senior...!"

Yukina didn't seem to expect that Luo Zhen would break into her house directly, and by the time she reacted, Luo Zhen had already arrived in the living room.

"It's emptier than I thought it would be..."

Luo Zhen, who was standing in the living room, looked around, his face full of helplessness.

I saw that the surroundings were empty, not even a piece of furniture, not like a place for people to live at all, more like a rental room waiting to be transferred.

"Looks like I'll have to buy furniture for you next time."

Luo Zhen said.

"No, no, even if I'm at home, I'll focus on Shikigami's side, I don't need to watch TV, I don't need to sit on the sofa, I just need to have an open space for me to settle in."

Yukina shook her head and spoke like this.

"Aren't you afraid that when a classmate or friend comes to your house to play, and there is nothing to entertain?"

Luo Zhen asked rhetorically with a roll of his eyes.

"I don't have that kind of reservation, and I don't play with my classmates and friends, and I don't bother."

Yukina replied quite inwardly.

Luo Zhen turned around and looked at Xue Cai.

"Senior?"

was stared at by Luo Zhen, and Yukina arrived a little uncomfortable, and called out as if at a loss.

"What the hell is wrong with you?" Luo Zhen didn't beat around the bush, and asked directly: "During the period when you came back from school, you didn't say a word, and you were silent by yourself, do you think I didn't find out?" ”

Hearing this, Yukina was dumbfounded.

In this case, Luo Zhen continued.

"You're like this because of what happened to Asttaruti, right?"

Luo Zhen said this in an affirmative tone.

If you think about it carefully, you know that after Luo Zhen revealed what happened to Astaruti, Yukina's feeling changed, not only became silent, but also rushed out without hesitation when Astaruti's beast went berserk, and used the "Seven Type Assault Demon Suppression Machine Gun" called "Xuexia Wolf" to disperse its rampaging beast and save Astaruti.

This shows that Yukina also empathizes with what happened to Astaruti.

That's right.

It's empathy.

"Because you're also a prop that the Lion King has specially cultivated and thrown away when it's used up, right?"

Luo Zhen's blunt words made Yukina bite her lip.

Obviously, Luo Zhen was right.
