"What do I ...... If it's me, of course I'll choose NEO......," Xia Aya replied helplessly, "Look at how difficult it is to synthesize things now, there are many things here that are different from the game, and if you want to synthesize them, you have to try for a long time to try them, and some can't even try, if you have NEI, it's much easier......"

"NEI can let itself know how to craft something when it wants to craft something with a block, or if it wants to craft something, so it will be much easier for us to make things, and we won't have to go through so much trouble anymore. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ”

NEI item manager is definitely a very practical thing, whether it is synthesis or other, and even the production and operation of other machines can be known in NEI, it can't be said that those who use NEI are novices, but novices without NEI are definitely not good at playing MC, and they can't play unfamiliar mods.

Although Xia Aya is definitely not a novice to the original MC, but in this world, in the face of all kinds of strange machinery, and there may be those mysterious magic, she is definitely the youngest white Xiaobai, how can she live without EI?

Su Qing naturally knew what NEI was, and after hearing what Xia Aya said, her eyes lit up and she exclaimed, "NEI! Why didn't I think of it...... Indeed, with NEI, everything we do will be much easier, and we won't have to go through the hassle of making things......"

"Uh-huh......" she nodded slightly, "If we can only choose one mod to upgrade the world, then choose the NEI you said Aya." Magic or something, compared to NEI, it's insignificant......"

Xia Aya was noncommittal, of course NEI wanted it, but magic was a thing...... To be honest, she is also very excited.

"It's not a definite conclusion yet," Xia Aya shook her head, "Maybe we can add two or more mods...... Of course, it is also possible that we can't choose the so-called added mods at all, but randomly ......"

Closing the book of the guide with a "snap", Xia Aya took Su Qing's hand and walked down the castle, "As the saying goes, it's better to choose a day than to hit the day, I think the gold ingots in the smelting furnace should have been smelted, so it's better to directly deliver the thirty-two gold ingots, the next stage of the task can be started, and we can also add modules." ”

So, the two of them came to the Craftsman's Soul Smelting Furnace under the mine, and after pouring out the thirty-two gold ingots, Xia Aya opened the Book of Guides......

Both of them were a little nervous at the moment, after all, once this task was delivered, it would be extremely important to them, and even a choice that would change their lives in the future would begin to upgrade the world, and they didn't know ...... Mods added, what the hell will it look like.

Xia Aya swallowed lightly, then reached out and lightly tapped the word "deliver" on the taskbar.

As a strange but familiar sound of the quest was completed, the gold ingots in Xia Aya's backpack disappeared and were replaced by some quest rewards, and before she could check them, her excitement tightened by the hints that appeared in her head.

"The first stage of the quest reaches 72%, the second phase of the quest opens, and the second phase of the quest is to develop the 'Rotation Craft', which is a very powerful technology mod that can even mine the bedrock ......"

Xia Aya didn't bother to listen carefully to what kind of module the rotation process was, except for the few words "can dig bedrock" made her care a little, so she lost interest, presumably digging bedrock is just a special effect in the game, where is there any bedrock in this world.

Su Qing is the same, their mood is nervous and excited, they don't care about the rotation process at all, what they care about is the choice of adding mods!

A "tirade" that was extremely long and even a little verbose in the hearts of the two of them, and actually didn't say a few words at all finally ended, and then a sentence in their minds directly suspended the hearts of the two of them to the limit, and it seemed that they would have to fly a little higher.

"The second stage of the task is unlocked, and then the host can choose to add the module independently, and the addition program will start in ten seconds, ten or nine ......"

The two glanced at each other, and they both saw the excitement in each other's eyes, and the highlight finally came!

When the number in their minds reached "one", the two of them felt blurred in front of their eyes, and then lost consciousness......

When the two woke up, they found themselves in a white world, and the soles of their feet were a dark void, which also made their minds a little nervous, and they even dared to maintain their previous movements, afraid that if they moved a little, they would fall.

It's like the kind of glass plank road that is completely hollowed out underneath, just looking at it, I feel soft all over, how dare I move?

Turning their heads and seeing that the other party was still by their side, the two of them were also inexplicably relieved, grabbed each other's hands, and then slowly stood up, stepped forward a few steps, and found that this was indeed a structure similar to a glass plank road, but it was more mysterious, although it was a void below, but even if it was bouncing, it would not fall.

"Two brave men...... Welcome to the World Library. ”

In the void, there was a sudden sound of turbidity and righteousness, which made the hands of the two hold together slightly clenched, dissolving the other's tension and some fear.

As soon as the words fell, almost instantly, layers of bookcases suddenly grew from the ground around them, like saplings that suddenly grew in the game, giving people an inexplicable weirdness.

There are more and more bookcases, which seem to extend infinitely in four directions, and at this moment the two of them can no longer see the changes in the edges, and everywhere they look, there are large tracts of different books......

"Wow......" Xia Aya couldn't help but open her mouth and gently spit out the shock from the bottom of her heart...... How many books should there be? A piece of bookshelves, the books in them are not too much to calculate in tens of thousands, and this kind of bookshelf is not the three wooden shelves composed of six wooden boards, but a real bookcase......

Each bookcase is about three meters high and two meters wide, and it can hold at least a hundred books, and there are hundreds of bookcases as far as they can see......

The number of horrors is worthy of being called the "library of the world......

It's just here......

The two of them are wondering, what does this place have to do with their addition of mods and the improvement of the world?

The next moment, a man dressed in a white robe, with a pair of sword eyebrows under his eyes seemed to contain a sky full of stars, his long hair was flowing freely, and he had a natural temperament all over his body, suddenly appeared in front of them......
