It's a thing to think about.

Xi Tong only saw the key to the parallel world in Yang Dingye, and it was still in the experimental stage, so it was unclear whether he could continue to look for other parallel worlds.

After all, not every world has Yang Dingye's "self", and not every world's "self" can get in touch smoothly.

Yang Dingye may be a key, but it must be inserted into the keyhole of the right number to open the door, and it is in vain to insert the wrong one or the wrong size and insufficient length.

So, is there a master key?

Should this master key fall into the hands of Heaven or the Olympian Protoss?

Xi Tong thought carefully and carefully sorted out the similarities and commonalities of many parallel worlds on Earth.

There must be one thing in common in these worlds so that they can resonate and overlap.

Although there is no intersection in the physical sense of parallel worlds, the intersection on the spiritual level has always existed and has always existed.

Each parallel world is stripped from the inflection point of history, and this inflection point is their common intersection.

So, do many parallel worlds have a common intersection?

First of all, there is no doubt that the subjects of the parallel world system are all human beings.

However, there are too many worlds in which humans are the main body, and this cannot be the key to parallel worlds.

Technology?

It's not right, after all, the civilization trajectory of each world is different, not all worlds have embarked on the path of scientific and technological civilization like the earth, and there are still many worlds that still maintain the path of cultivation, and technology is only an auxiliary on the path of cultivation.

For example, the Ming world.

Xi Tong shook his head, he found himself walking into a misunderstanding.

The key is a key because it can open the entire door through a small keyhole and enter the house.

It doesn't need to be a technological civilization in the whole world, even a handful is enough.

All it takes is a place to stand and it is enough to start a prairie fire.

For example, the United States of the West in the Ming world, this regime has too many similarities with the earth, and its ideology, culture, history, religion and other aspects are the same as the Western world on the earth.

Even the way they date is ......

Wait a minute......

Xi Tong vaguely understood the key.

Chronology.

The year of the Common Era, or the year of Jesus, is practiced on earth, and the year of Jesus' birth is regarded as the first year of the Common Era.

This method of dating is also used by the Western United States of the Ming Dynasty.

If you think about it carefully, the world of the Qing Dynasty and the world of Yang Dingye are also in the Common Era.

It is this method of chronology that connects the histories of several worlds, and although they have become very different from one point in time, all the histories have been strikingly consistent until then.

Even if there are discrepancies, they are the result of later generations' records, deletions, and distortions.

Xi Tong sat cross-legged, the back of his right hand pressed against his knee, and his fingers pinched quickly.

His movements are extremely fast, but instead produce the illusion of slowness, and the space and even time in his palm stop flowing and moving.

Xi Tong didn't know what he was doing.

It was a pure whim, but the result of the deduction made him gasp.

He guessed correctly, Heaven relied on the Common Era to find a parallel world system.

Heaven's purpose in doing this is not only to obtain the resources of the parallel world, but also to sacrifice a powerful thing that surpasses the artifact of creation.

Click!

Click!

A pair of walnuts turned into the remains of the Eastern Emperor Bell spun rapidly in Xi Tong's hands.

Xi Tong finally understands Heaven's ambitions.

They are to sacrifice all the worlds in the parallel world system, and to refine the rules of time.

Maybe it's a divine art, or maybe it's an artifact, in short, its power is time.

Donghuang Zhong suppressed the flood and condensed the rules of time, because the world it was in was close to the source of the parallel world system, occupying an innate advantage, and it only needed to connect a pipe to have water to drink.

The many parallel worlds of the earth are the end of the parallel world system, although it requires tedious sifting and gold panning, but it is superior to the huge volume, easy to accumulate, as long as you put in the effort, you will definitely gain something.

In the Common Era, it passed through all worlds and was deeply rooted in the hearts of the people, and even Xi Tong, a powerful existence, was accustomed to it, and regarded it as one of the elements of the world, not to mention other worlds, the powerhouses of other worlds.

Click!

A voice rang out that could be clearly perceived, but did not actually exist.

Xi Tong felt loose, and the walnuts in his hands turned more smoothly and quickly.

Sure enough, Heaven is trying to seize the rules of time from the parallel world system.

There are some things that cannot be said to be seized by others, but can only be said to be that they do not pay attention to themselves.

But when Xi Tong attaches importance to this, heaven has no chance.

Because Xi Tong has a seed of time rules in his hands.

It's like a singularity that will absorb the power of time and eventually form rules.

At the same time, Yang Dingye looked at the system interface with dull eyes.

"Ding! The system quest [New Era] asks the host to influence the government and abolish the A.D. era and change it to another era. ”

"Mission Details: Reiki revival has begun, a new era has arrived, and a new chapter has been opened for human civilization, and this is a time to say goodbye to the old and welcome the new. Change starts with time. ”

Yang Dingye looked at the time and date on his mobile phone, looked at the printing time of the books on the table, looked at the expiration date of the fat house happy water, and looked at the ......

Changing the epoch is not a matter of lip service.

Let's not talk about the distance, the millennium worm knows, just because of the way the time is calculated, the whole world is tormented and restless.

Another one is last year's Linghe Yuan change, which tossed the island country into a bad place, and what is even more terrifying is that this toss comes every few decades.

And the task given by the main god of the system is more thorough than the order and the change of the yuan, not to change a small era name, but to change it from now on, and all of it will be changed from now on.

The "BC" and "A.D." in the historical records will not appear again, and there is no need to think about 9102 or 0202.

It's not just the years that change, it's everything that is closely connected with the years.

This is no longer a matter of moving the whole body, but of moving the whole world, history, and civilization.

Yang Dingye's only feeling is that his head is big.

It is already extremely difficult to convince the government with this, even if the government is persuaded by itself, what can it use to convince the people?

Even the person who received the task of the system felt extremely inconvenient and uncomfortable, let alone others?

However, Yang Dingye had no choice.

The system does not issue tasks for no reason, and every task it issues represents the will of the main god of the system.

The main god of the system is not something that he can figure out, and the only thing he needs to do is to obey orders.

It's just a change of chronology, what's the big deal.

It's uncomfortable for so long, and at most it's just a generation.

It's just a change in living habits, and it's not a matter of cutting flesh and bloodletting.

However, why is the only thought in my heart to hurry up and drink up the happy water in the fat house at home?

Because it's about to expire.

Even the "production date" is about to "expire", isn't Happy Water still expired?
