Three minutes later, the three of them came to an open square.

As you can see from the marks on the ground, the square was built improvised, and the surrounding area was originally full of buildings, but it was demolished and built into a huge square.

A huge black hemisphere looms in the middle of the square.

"This black hemisphere is not an empty thing, it can be touched, but it requires a password to enter."

Selena walked up to the black hemisphere and reached out to make contact with it.

Ripple-like ripples appear on the black hemisphere, forming three lines of text and a blurred line.

[Please answer the following questions:]

[1. What is the most important item preserved here?] 】

[Second, who did you get the news from?] 】

The first requires manual input, and the second is to select a figure from a line of blurry images.

"Neither of these questions can be answered, and neither is the messenger of the Sun City. And if you answer incorrectly, you won't have any response if you contact it again for a month. ”

Selena reminded.

"It's up to you, and besides, we're running out of time." Skymark looked at Chen Bing, a question he couldn't answer.

The rumbling behind him grew louder and louder, and the Devourer was still chasing after him.

Chen Bing must give an answer as soon as possible, or he will be caught up by the Devouring Demon.

Once that's the case, Chen Bing is in danger.

Chen Bing didn't speak, he strode forward.

The first question is simple, and it must be the core of the steam engine.

But for the second question, Chen Bing looked at the row of figures displayed on the black hemisphere, but he didn't choose it at the first time.

"What's wrong, isn't the image clear?" Skymark asked nervously, the sound behind him getting louder and louder.

"No, ten choices in total, but none of them are anything I've ever seen. I'm afraid that the images of these ten figures are all fake, and as long as you don't know the answer, you will never be able to answer. ”

Chen Bing shook his head.

"I'll go, won't I? Is this a trap? "Skymark was stunned, he had been given ten choices, who would have thought that all the choices were still fake?

"What then?" Selena was also stunned.

She never imagined that the choice given would be problematic.

"It's easy, just draw another one."

Chen Bing stretched out his finger and quickly drew a figure under the ten choices.

He didn't know who left the message, but the ten figures above weren't given out randomly.

If you compare carefully, the ten figures are all somewhat similar.

When Chen Bing compares with the people he saw in the video of the underwater ruins, he can find that on the images of the underwater ruins, the woman who initially spoke faintly is most similar to the figures of these ten choices.

A figure quickly formed under Chen Bing's fingers, and after Chen Bing drew the woman, he moved her to the second question with a light touch of his hand.

[Answer is correct!] 】

On the black hemisphere, the problem disappears, replaced by another line of text.

That's it!

Tianji looked at Chen Bing speechlessly.

When he was still thinking about what Chen Bing was going to do, Chen Bing drew out the answer by himself at an incredible speed.

Selena also looked at Chen Bing in surprise, feeling that this person was becoming more and more unusual.

The moment the words appeared, the black hemisphere disappeared silently, revealing the entire square.

"It's ...... Book? ”

The black hemisphere is huge, but very little is preserved inside.

Skymark glanced in, only to see a few rows of bookshelves.

It's just that in the middle of the square, there is a huge stone treasure chest one meter high.

"Farmland planting, seed breeding, fertilizer manufacturing, steel smelting, building foundations...... All of them are very valuable knowledge books on development and construction, and with them, the development speed of the tribe has increased dramatically. ”

Skymark looked at the books on the shelves, he wanted to pick up a copy and flip through it to see what had been written, but when he reached over, he found that the books and the bookshelf seemed to be glued together, and as soon as he pushed hard, the whole book turned into powder and scattered with the wind.

"Can't get these books?"

The sky is scarred.

"No, it should be possible to take it out, but it will take a lot of time to carefully dispose of the parts that stick to the bookshelf." Chen Bing took a closer look and shook his head.

The civilization coefficient of the books that record knowledge must be above 2.0, which is within the destruction range of the light of civilization destruction.

Although the place has been specially protected, the books have been affected and become extremely fragile, which can be destroyed if you are not careful.

Thinking of the approaching Devouring Demon, Chen Bing suddenly knew that there was no such thing as a free lunch.

If you want to get these books, you'll have to find a way to fight the Devourer.

And if you want to win the Devouring Demon, you can basically only wait for the late game, when the strength is strong enough, it is possible.

At this stage, no matter who comes, they can only drop these books and evacuate first, and only after they are strong enough can they come and take them again.

But by that time, the books weren't really very useful, and they weren't as useful as they were at the beginning of the game.

After all, there are plenty of other prehistoric ruins in the game.

"It's a pit, you can only see it, you can't take it." Skymark couldn't help but complain.

They had to get out as soon as possible, or by the time the Devourer caught up, all the books would be destroyed.

Chen Bing ignored the books, and walked quickly to the stone treasure chest.

There was no other tricky place on the stone treasure chest, and Chen Bing opened the treasure chest with a little force.

Inside the treasure chest, a black metal cube with a diameter of more than half a meter is placed.

In addition to the bottom of the metal cube, the remaining five sides each have a valve mouth of different sizes, as well as a variety of delicate accessories interfaces.

Next to the metal cube, a large number of drawings are placed.

Chen Bing picked it up carefully and found that they were all drawings of the accessories of the core of the steam engine.

This metal cube is undoubtedly the core of the steam engine, but it is only one core, and it needs to be moved and the corresponding parts to be manufactured.

"The core of this steam engine can't fit into a backpack, but it's so lightweight, and it doesn't look like metal."

Chen Bing tried to put all the contents of the treasure chest into his backpack, the drawings were fine, but the steam engine core was not, so he could only take it away.

Originally, the weight of this large piece of metal would inevitably be very heavy, but Chen Bing easily lifted it, and roughly estimated that the weight was only about ten catties, which was quite light.

"It's even harder to leave with this thing, the Devourer is about to chase after you, let's get out of here."

Scar hurriedly spoke, the Devourer had arrived not too far from the square, and only the last bit of the building was still blocking him.

But at the current speed of the Devourer, it doesn't take 30 seconds to catch up.

When the Devourer demolished the building, he was much stronger, and he was able to demolish the building very quickly.

"No, I think we can try to kill this boss."

Chen Bing didn't rush to leave, stood up, and looked at the Devouring Demon who was still engaged in demolition.

"How to fight, this guy is much stronger than a while ago."

Tianji was speechless, he couldn't kill him a while ago, and he only came to kill now, how could it be possible?

If they could be killed, the three of them wouldn't have to be chased so hard.

"He's a boss, but don't forget, we have a boss too."

Chen Bing smiled.

"You say we use special scrolls to summon bosses to deal with Devourers? But is it possible? What if the summoned boss comes out and deals with us with the Devourer? ”

Skymark frowned.

Chen Bing thought very well, but it was impossible to operate, and the summoned boss would not help them kill the Devouring Demon.

"The summoned boss will definitely attack us, but it will be a normal boss, and whoever does high damage to it, its hatred will definitely be attracted to it. And if I'm not mistaken, after we summon the boss, the hatred of the Devourer will be locked on the boss. The Devourer will chase me, and most likely my attributes and vitality are the strongest! ”

Chen Bing analyzed.

At first, he thought that the Devouring Demon was the original boss of the ruins, but after knowing that it was the Sun City Emissary who had become, Chen Bing knew that he was being targeted for another reason.

One possibility is the Sun City gold coin he carried

Another possibility is that his life force is the strongest of the three, causing him to be locked by the Devourer.

Combined with the Devouring Demon's continuous devouring evolution, Chen Bing thought that the second possibility was very high.

The Void has a limited amount of energy to the Devourer, but the Lifeform provides much more evolutionary energy.

This can be explained by the fact that the Devourer initially left Selena's mother into the Voidish, attacked Selena, and then it dropped Selena to ignore the Celestial Scars and attack Chen Bing.

When Tianji heard this, he felt that Chen Bing's analysis was very reasonable.

If Chen Bing's analysis is correct, the boss they summoned will instantly attract the hatred of the Devourer, and then the Devourer will fight the boss, and the two of them can take advantage of the fisherman.

As far as the result is concerned, whether the boss is killed or the boss wins, it is a good situation for both of them.

"You use your scroll to summon first, and if the analysis goes wrong, the boss you summon won't be too strong. When the time comes, I'll lure the Devourer away, and with the help of the terrain, it's not too difficult to kill the boss. If the boss pulls the hatred, I'll summon another one and deal with the Devourer. ”

Chen Bing added.

"Alright, let's do it!"

Celestial Scar listened, and no longer hesitated.

Chen Bing has thought it through, and the risk is still there, but it has been reduced very little.

And if you can kill the Devourer, the reward will be huge.

It is highly likely that the Devourer will drop the relic equipment carried by the Sun City Emissary, killing the Devourer, and they will also have enough time to take the books around them.

With these books, the hierarchy of the tribe would skyrocket.

"You ...... Can you really kill that Devourer? ”

Scar and Bing Chen rushed towards the Devourer, Selena following closely behind, asking nervously.

Of the three, the one who wants to kill the Devourer the most is undoubtedly Selena.

Although her mother was okay this time, there was no guarantee that she would meet her again next time, and no one would be able to save her.

In fact, as time went on, there were fewer and fewer nihilists, and it was only a matter of time before her mother was devoured.

"I don't know yet."

Chen Bing shook his head and didn't promise Selena anything.

"Roar!"

The Devourer had already reached the edge of the square, and it looked at Chen Bing and the three of them, and with a roar of rage, it collapsed several buildings with a single punch, and rushed towards the three of them.
