Next, Jiang Li and Xiao Ling'er separated.

Because they were online at 10:50 on this day, and it's now 2 pm, there are still more than 8 hours of online time.

Jiang Li came to the engineering branch union.

The reason for being here is simple.

The heart of the Ranger!

After the Black Forest took out the patrolman, Jiang Li picked up its core and planned to take it to ask Lin Yang.

"Hmm......" Lin Yang kept turning this core full of sci-fi texture, "This energy core is very advanced, obviously the frequency is only 1GHz, but it can provide such a huge energy ......"

Jiang Li had already told the inspector in the Black Forest about it at this time, and he asked:

"According to what I've found, the Inspector was produced in 202."

"202 ......" Lin Yang fell into deep thought, "In fact, in my decades of study, I have always had a conjecture in my heart, and seeing this energy core you brought, I am even more certain." ”

"What is it?" Jiang Li asked.

Lin Yang stared at Jiang Li and said word by word, "I think that the world of Lyle hundreds of years ago had more advanced technology than it does now, and it was an even higher civilization than it is now!" ”

"You mean civilization has regressed?!"

"Almost, the previous Lyle world should have been very technologically advanced, but for some reason, civilization has regressed or even destroyed, and the Lyle world has had to develop from scratch, and then it has only developed like this in 922 now."

I have to say that Jiang Li was shocked that this world had regressed civilization once.

HE SUDDENLY REMEMBERED POSA.

Who is that girl?

Pothos Town Library.

Every town in the world of Lyle has a library.

It contains a list of various aspects of Lyle's world.

A lot of players also come here to check the information.

Because the background of Lyle's world is extremely complex, looking up these things can help them understand the background of the world and speculate on the future direction of the plot in order to develop better.

Of course, there are also people who try to find powerful skill books and spell books here.

Judging from the forum on the official website, someone has indeed found it in a place like the library, but the probability is very low.

POSA stood on the corner of the street across from the library's entrance, watching the players frequenting the library.

"Stealth mode."

WITH POSA'S BEAUTIFUL VOICE, A WAVE OF ENERGY SWEPT OVER HER PERFECT BODY, AND THEN HER WHOLE BODY DISAPPEARED INTO THIN AIR.

She walked in.

…

Very quiet inside the library.

Tall bookcases are neatly filled with old books.

The sound of flipping books can be heard here.

POSA walks in it.

She came here to find out what had happened in the last seven hundred years.

She is a highly intelligent robot created 700 years ago, and she doesn't understand why the technological civilization of the world has regressed to such an extent.

POSA walks over to the shelves where the history books are located.

She flipped through all the books on Lyle's world history.

"Since 700 years ago, the rest of the history is unknown to me......"

That's right, she has been asleep for more than 700 years, and it's normal to not know.

She kept flipping forward.

"This !!"

POSA looked at the contents of the book in shock, "The history from 202 to the beginning is different from what I knew!" ”

History has been tampered with?!

Why?

Such a highly developed civilization is buried in the long river of history?

What's going on?

POSA WAS AT A LOSS.

Seven hundred years have passed, things are not people, what should she do now?

POSA WAS STUNNED FOR A MOMENT, AND HER OCEAN-BLUE EYES WERE DULL.

"By the way, what about her, ZK105......"

Her code name is ZK104, and the ZK105 she works with doesn't know what happened.

But how did she find the ZK105?

She picked up a copy of "Lyell's History of the Development of World Engineering" and looked at it.

But when she looked at it, she found something different.

"No, even if it's a new development, this engineering is developing too fast......"

It's a bit like the tech tree is crooked.

Why?

She thought of only one possibility.

Seven hundred years ago, there must have been something left behind, and human beings redeveloped civilization based on those things.

"There is no federation in the current world of Lyle, several countries are separated, but engineering is all managed by one institution."

POSA took out the current map of Lyle's world and looked at it.

Finally, point to a place in the center of the map.

"Sky Island, Engineering Guild Headquarters!"

You have to get in there, or you won't know the truth.

But—

POSA CONTINUED TO FLIP THROUGH THE BOOK IN HIS HAND.

It is not so easy to infiltrate the headquarters of the engineering trade union, which is currently the most technologically advanced in human technology.

To be able to build a hanging island, this engineering union headquarters is more powerful than expected.

"Has the world developed an information network?" She suddenly remembered Jiang Li and the others.

Since those humans can open the projection panel to view their own properties, it means that the network should still exist.

She, ZK104, happens to be the best at virtual networking!

"If you hack into the network of the engineering headquarters, you may be able to ......"

This is more convenient than her sneaking in, if she can hack in, she can find out a lot of useful information, and even the truth from seven hundred years ago can be found out.

"That's it for now." She turned and left the library.

"Huh? Who reads a book and doesn't put it back? It's really ......."

A LIBRARY ADMINISTRATOR RUBS SHOULDERS WITH POSA.

Jiang Li has been leveling for more than eight hours.

After all, there is no black iron ore, and his arrow tower manufacturing plan is estimated to come to an end for the time being.

"We must find out the inner ghost and recapture the black iron ore!"

Otherwise, he and Xiao Ling'er would not be able to move an inch in Luluo Town!

But speaking of which, the worldview of "Fate" seems to sound huge this time.

Regression of civilization?

If you think about it, engineering in this world is indeed very developed, and in life and occupation, blacksmithing, medicine, planting, tailoring, etc., are far less useful than engineering.

"I don't know what the main plot is, but I always feel like it......"

Jiang Li glanced in the direction of Green Pothos Town, and he always felt that all their players had been involved in the incredible plot.

And just like that, time went by.

Jiang Li, who went offline at 11 o'clock in the evening, immediately ate something casually, took a shower, and continued to go online at 12 o'clock.

Jiang Li understands that whether he can find out the real inner ghost depends on tonight.

…

In Luluo Town, Jiang Li, Night Warrior and others, as well as the main forces of the four major guilds of the Night Shadow Guild, the Falling Flower Star Rain Palace, the World Without Dispute, and the Full Moon West Building, all gathered together.

"So, why are they here?" Bing Ning looked at the president who had no quarrel with the world, and the president Qingqiu, who was full of moon, in the west building.

"They intend to act with us." Jiang Li said.

The mine was seized, and the black iron mine that had no quarrel with the world and the full moon in the West Building was naturally gone, so they also joined forces with Jiang Li and others.
