Startled, Uchiha Yunqing abruptly looked up at Uchiha Mikoto, his face full of astonishment.
"Mikoto, you heard that too?"
"Yes!"
Uchiha Mikoto nodded, her expression filled with uncertainty.
"I heard it!"
"Let's go! Let's go take a look!"
Uchiha Yunqing immediately jumped up, grabbed Mikoto's hand, and rushed out of the house. Once they stepped into the courtyard and looked up, they saw a gigantic portal of light—hundreds of feet tall—standing in the sky. It was half-real and half-illusory.
It seemed close, yet impossibly far, as if it could never be reached.
In fact, it wasn't just the two of them. Nearly everyone in the entire Ninja World had been alarmed by this disturbance. The already turbulent world was about to be plunged into even greater chaos.
"This is the space-time portal?"
Yunqing and Mikoto stared blankly at the enormous gate, murmuring unconsciously.
The moment they looked at it, information about the portal and its rules automatically flooded into their minds.
[Portal Travel Rules]
The portal can only be used once every five days.
The portal can only be activated after five minutes without combat.
Your initial landing location in a new world is random. After that, your landing point will always be the same as your last departure point. Be wary of ambushes.
Intelligent life from lower-level worlds may enter higher-level worlds without restriction. Intelligent life from higher-level worlds may enter lower-level worlds, but restrictions vary depending on the individual and world tier.
Age requirement for portal travel: 18 years old or above, or an equivalent adult intelligent life form.
...
"It really works! Doesn't this mean my daily sign-in system is useful again?"
After absorbing the information, Yunqing felt a surge of uncontrollable excitement.
There's always a way out!
I thought the system was going to be useless, but this is a turning point!
"Wait a second… System, isn't this too much of a coincidence? Could this space-time portal be your doing?"
Suddenly sensing something strange, Yunqing questioned the system in his mind.
[No. This is the work of the Heavenly Dao of all realms and the Creator God. It originated from an unexpected space-time turbulence, causing the realms to converge and merge irreversibly.]
"Oh?"
Yunqing raised an eyebrow, surprised.
So that's how it is?
He suspected that this so-called "space-time turbulence" might have been caused by the system bringing him across worlds in the first place.
But in the end, he didn't press the matter.
Because it no longer mattered.
All he needed to know was that the appearance of the space-time portal was a good thing for him.
If he wanted to become stronger faster and obtain more rewards, he would definitely use the portal to travel to other worlds.
At the same time, he could use the resources of those worlds to strengthen himself even further.
Just then, the portal displayed new information.
A world would merge with the Ninja World in five years.
In order to ensure a smooth fusion between the two realms, the portal granted most adult intelligent life in both worlds the right to travel freely between them.
The world's name was: The Pokémon World.
A short introductory video also appeared, providing basic information about the Pokémon World.
Meanwhile, the Pokémon World experienced the same phenomenon. However, the video displayed through their portal was titled: "Ninja World."
"This world… I know it well!"
After receiving the message, Yunqing's eyes lit up as he watched the Pokémon World's introduction.
Although he hadn't watched much Pokémon anime in his previous life, he had read plenty of fanfiction and was extremely familiar with the setting.
Compared to the Ninja World, the Pokémon World was far better. Calling it a semi-utopia wouldn't be an exaggeration.
Of course, it could also be a dark Pokémon world.
But no matter what, it was still much better than the Ninja World.
More importantly, Pokémon weren't just loyal and cool—they were also incredibly powerful allies.
Even without considering the daily sign-in rewards, Yunqing had already decided he would definitely visit the Pokémon World.
"However, exchanging territory with the Ninja World might not be a good thing for the Pokémon World…"
"The ninjas—and even the humans of this world—aren't like the humans in the Pokémon World. They have more flaws, and their morals are far worse."
"I wonder if Arceus and the others have any countermeasures."
Yunqing couldn't help thinking.
He genuinely didn't want the Pokémon World to be thrown into chaos by greedy and ruthless ninjas.
…
At the same time, within a hidden realm of the Pokémon World, many Legendary Pokémon gathered.
After watching the Ninja World's introduction through the portal, Ho-Oh frowned slightly.
"So it's finally begun… A world full of slaughter and distortion."
"Arceus, is it truly a good thing for our world to merge with such a place?"
Most of the other Legendary Pokémon nodded, their gazes turning toward Arceus.
Arceus spoke calmly.
"This is not something we can choose."
"The merging of worlds is irreversible. All we can do is establish rules to prevent and limit the persecution of Pokémon, and guide the people of the fused world onto the correct path."
"With these restrictions in place, and with the temptation of Pokémon contracts, I believe most humans will know how to make the right decision."
"Besides, isn't this merger also an opportunity for us?"
"As worlds merge, the upper limit of power will inevitably rise."
"As long as we spread Pokémon across all realms, our authority will expand, and our future will become far broader."
"Therefore, everyone—fulfill your duties and do your best to guide them."
The Divine Beasts responded in unison.
"Yes!"
The next moment, Arceus opened a portal and transmitted the relevant rule information into the hearts of every intelligent life form in the Ninja World.
As for the Pokémon World…
The rules had already been delivered.
"Hm? Arceus really does have preventative measures!"
The next moment, Yunqing received new information regarding Pokémon and the laws of the Pokémon World.
[Pokémon World Rules]
Pokémon Entry and Exit Restrictions:No more than twelve non-contracted Pokémon may be brought out at a time. Each person is limited to one entry and exit per month.
Pokémon Contract System:Each trainer may condense one Pokémon Contract Mark for every major level of Spirit Power they reach.
Trainers can form contracts with Pokémon through the contract mark, allowing both sides to grow together and benefit mutually.
The Pokémon Contract provides effects such as:
Increased Spiritual Resonance
Feedback of power and abilities
The feedback ratio is directly proportional to the level of affinity between trainer and Pokémon.
The contract also enhances a Pokémon's growth speed, increases its talent and strength, and may even help it break through its potential limits.
The number of Pokémon a trainer can contract is related to:
The trainer's mental strength
The openness of their Pokémon Contract Space
A trainer cannot contract a Pokémon whose level exceeds their own mental strength level.
Pokémon Protection Rule:No one may abuse, kill, or harm a Pokémon without reason.
Otherwise, they will be rejected by Pokémon and even by the Pokémon World itself.
The more Pokémon someone persecutes, the stronger the rejection becomes, making it harder and harder to form contracts.
Even if they manage to contract a Pokémon, affinity will become extremely difficult to increase and may continuously decline. In extreme cases, the Pokémon may even break the contract and defect.
Breaking a contract causes backlash to both the trainer and the Pokémon.
The greater the fault of the guilty party, the greater the backlash they will suffer.
Rejection from Pokémon and the Pokémon World also applies outside the Pokémon World, within the Fusion World.
Of course, normal battles, accidental deaths, and non-malicious conflict do not count.
In addition to these rules, the information also included:
Methods for condensing Pokémon Contract Marks
Techniques for creating a Pokémon Contract Space
Basic meditation and Spirit Power training methods
These were rules specifically modified by Arceus to prepare for the merging of worlds, designed to increase the strength of humans in the Pokémon World.
At the same time, they further bound humans and Pokémon together, greatly reducing the chance of humans abusing, harming, or abandoning Pokémon.
Of course, spreading these rules to other worlds served another purpose as well:
Protect Pokémon… while expanding Arceus's authority.
