This second dimension is too immortal

"By the way, in addition to Irisviel, we have also prepared a very good helper for you. I believe that with him, your chances of winning will increase a few points." said the old man.

"You mean... him?"

When the man's voice came, Zhao Si clearly felt that both of their eyes were on him.

"Yes, his existence was an accident, but certain changes in him made us keep him," Lao Bangzi introduced.

"Change?" the man whispered.

"That's right! His physical functions are almost three times stronger than those of an ordinary person. With a little training, I believe he will be your most powerful helper in the Holy Grail War."

Three times that of an average adult?

When Zhao Si heard this, he was stunned.

When did I become so weak?

Are you kidding me? I'm a cultivator who has reached the Golden Core stage and has even withstood the physical tribulation of thunder. And you're telling me I'm only three times stronger than an average adult?

Who are you looking down on, you stinky little brother?

"Ok?"

But at this moment, Zhao Si was surprised to find that his physical state had become extremely weak for some reason. Not only his physical body, but Zhao Si looked inside himself and found that there were two dark red chains in his dantian, which were tightly binding his dantian, and all his cultivation was sealed.

"System, what's going on?"

Zhao Si asked in a bad tone.

[Host, do not worry. Since this is your first time using the intervention mode, your own strength will be temporarily weakened. It will only take one day for you to recover to your peak strength.]

"One day? Why would there be side effects?"

After hearing this, Zhao Si felt a little relieved and then asked.

How can traveling through a world have side effects? That's too bad.

To be honest, Zhao Si obviously did not realize that no matter how much his own system looked like a system, it was essentially just an innate spiritual treasure comparable to the Nascent Soul stage.

Only when Zhao Si becomes stronger can the system become stronger. If we really want to delve into why time travel has side effects, we will probably only get one answer in the end.

It's you, Zhao Si, who's too bad! It's not my system that's wrong.

Otherwise, go and ask, which Nascent Soul stage treasure can reach my level?

As expected, in response to Zhao Si’s doubts, the system answered.

[Given that the host's own strength has only reached the Golden Core Great Perfection stage, the system's ability to eliminate the host's side effects is currently limited. If you wish to completely eliminate side effects next time, the host can choose a relatively weaker world. Alternatively, the host can quickly improve their own strength, which will naturally make the system stronger and thus avoid more side effects.]

The system's voice resounded in Zhao Si's heart.

Zhao Si was stunned when he heard this.

I don’t know if it’s an illusion, but Zhao Si felt that when the system said this, there seemed to be a hint of grievance in its words.

In addition, it was a female voice, which made it sound like an employee who had been working hard but was eventually criticized by his boss for his low efficiency, and was retorting in a wronged manner.

However, Zhao Si was quickly attracted by what the system said. After listening to it, Zhao Si was stunned again.

It seems, indeed, the system is an innate spiritual treasure. The stronger you are, the stronger the system will be.

So, the root cause of the side effects really lies with myself?

This is a bit embarrassing.

The corners of his mouth twitched, and Zhao Si felt extremely embarrassed.

Just as Zhao Si was asking the system, the two people outside the culture tank were also talking.

"You can think of him as Irisviel's older brother or younger brother. It doesn't matter. I believe you won't care about such a small matter." said the old man.

"Really... I see."

"Of course, you can also treat him as a pure tool and order him around as you please during the Holy Grail War without any worries."

"Uh-huh?"

The man agreed, and his voice suddenly rose slightly, with a hint of surprise.

"What's wrong?" asked the old man.

"...It's nothing, maybe I was dazzled. It seemed like the corner of his mouth twitched just now..." said the man.

Tsk, so perceptive? I was almost discovered.

Zhao Si came back to his senses and was a little surprised.

According to the system's information, I am now in a weak period. Just like what the old man said, my physical fitness is at most three times stronger than that of an ordinary person.

It would be fine if they were ordinary people, but the magician killer and heroic spirit they mentioned did not look like ordinary people at all.

In other words, how could an ordinary person be able to master such technology as cloning and artificial humans?

Therefore, when there is information asymmetry and you don’t know the other party’s strength, it is better to be cautious.

Zhao Si made a quick decision and decided to back off first.

"Slap your mouth?"

Lao Bangzi was puzzled, and after a while, he seemed to observe Zhao Si carefully.

"You must be dazzled. These androids have their own unique spells engraved into their bodies. They won't wake up automatically until the time comes."

"Of course, even if it does move, it's nothing. It's normal, there will always be some slight reaction."

The old man explained.

“…Is that so? I understand.” said the man.

"Alright, we've seen enough. Let's stop here for today. Let's go. When Irisviel wakes up in two days, you will truly be the son-in-law of the Einzbern family."

After Lao Bangzi finished speaking, the man didn't seem to object. After a while, the footsteps were heard again, gradually moving away.

"Bang!"

The sound of the door closing was heard, and the training room fell into silence again.

After a long while, Zhao Si opened his eyes.

"Interesting, this mission doesn't seem that simple..."

Touching his chin, Zhao Si thought.

The Holy Grail, the Heroic Spirit, the Magician Killer...

"It's something to look forward to."

Shaking his head, Zhao Si looked at the glass wall in front of him.

There were seven days left after the Battle of Heroes, so Zhao Si naturally wouldn't waste any time.

Finish the work early and go home early, and take home the Holy Grail, which is so wonderful.

"Hey, that's not right. That guy just said they won't start summoning Heroic Spirits until two days later?!"

Zhao Si was stunned for a moment, and suddenly he thought of this.

Since the group of people just now were participants in the Holy Grail War, and they haven't summoned Heroic Spirits yet, doesn't that mean the Holy Grail War hasn't started yet?

"This... system, the mission says, 'Holy Grail War for seven days,' right? If the Holy Grail War hasn't started yet, how do we calculate the time?"

[Of course, it is not recorded within the seven-day period.]

"So, I have to wait until the Holy Grail War begins?"

Zhao Si rubbed his head with a headache.

I promised Tohka and the others that I would be able to return in seven days, but now the Holy Grail War has not even started.

This...how should I put it, I didn't expect this at all. Zhao Si thought the fight would start as soon as he landed.

"Never mind. They'll summon the Heroic Spirit in two days. It's only a matter of two or three days of missing the appointment. It's not a big deal."

Zhao Si said to comfort himself.

However, if Zhao Si had known about this world and the Holy Grail War before setting off.

Then he would definitely recognize the woman in the incubator next to him, and he would also know that there is such a thing as advance summoning.

"Forget it, let's slip away first. I'm in a weak period now, so it's better to be careful."

Zhao Si thought about it and carefully observed the culture tank he was in.

After a while, Zhao Si frowned slightly.

It must be said that the quality of these instruments used to cultivate artificial humans is very high. Zhao Si searched for a long time but could not find a place where he could escape quietly.

"Tsk, is it just a matter of brute force?"

Since there is no opportunity, he can only create one himself. Although breaking it open violently will most likely attract the attention of the Einzbern family, there is no other way. Zhao Si has no choice.

Of course, with Zhao Si's current strength, he must be extremely careful and avoid risks as much as possible.

Looking up and searching around the room, Zhao Si was lucky enough to see a round clock on one of the walls of the room.

The hour hand above shows that the current time is nine o'clock in the evening.

"Well, let's wait a little longer. It's safer to run away in the middle of the night. It also gives me some time to recover some strength."

Zhao Si made up his mind, then closed his eyes and waited quietly for the opportunity to leave.

The night was deep, and a silver crescent moon hung high above the Einzbern Castle.

Silence enveloped the entire castle, with only sporadic lights dotting the darkness.

In the cultivation room.

Zhao Si suddenly opened his dark eyes.

"Half past two?"

After glancing at the clock on the wall, the dark environment appeared as clear as daylight in Zhao Si's eyes.

"time to go."

As he spoke, Zhao Si retracted his gaze, slowly stretched out his hand, and made a palm, with his fingertips pointing at the culture tank.

With his fingertips touching the culture tank, Zhao Si paused for a moment, changed his palm into a fist, and suddenly exerted force, smashing it on the culture tank.

"Click!!"

"Crack!!"

"Bang!!"

Under Zhao Si's attack, a spider-web-like crack first appeared on the surface of the culture tank, and then the crack spread rapidly.

When most of the surface of the culture tank was covered with cracks, the entire culture tank shattered and the nutrient solution in the tank flowed out violently.

At the same time, Zhao Si was naked, stepping on the wet ground.

at this time.

"Ok?"

Zhao Si had just walked out of the culture tank and hadn't even stood firmly when he heard a noisy sound of footsteps and shouts.

"Is it that efficient?"

Zhao Si's face changed slightly, somewhat unexpectedly.

It was obvious that the people outside had been alarmed by the noise made by Zhao Si.

"Damn, it seems like God doesn't want me to be too low-key." Zhao Si said with a pained look.

"Forget it, I can only force my way in. Fortunately, I have recovered some strength during this period of time, otherwise I might not be able to get out."

Sighing, Zhao Si looked around and picked up something that he didn't know whether it was a towel or a curtain and wrapped it around himself.

"I can't let you watch this for nothing."

Zhao Si chuckled and was about to leave.

At this moment, the system's prompt sounded in Zhao Si's ears, causing Zhao Si's expression to freeze.

[Ding! Since the host is currently in Intervention Mode, the quest chain is activated. The current conditions meet the quest activation requirements.]

[Ding! Mission successfully launched!]
