At this moment, Sun Li suddenly remembered many things that he had ignored before.

For example, the sentence that Dawa once accidentally said before, "From the beginning, there were so many rooms here." ”

Obviously, they didn't build it.

If you think about it, it can't be that they built it. These seven brothers have a slight problem with their minds, and it's okay to fight, but it's not okay to really build a big project like this Spirit Devouring Array.

The most important thing is that there is a real lack of vitality here.

In other words, it is very likely that this is not the end of the vitality, but just a transit station, and the seven brothers of the gourd are just the people who guard this transit station.

Transfer!

Sun Li took a deep breath, silently recited these three words several times, and then his gaze fell on the ground in the center of the hall.

"If this is really just a transit station, then the place of this array is the place that leads to a higher level, right?" Sun Li muttered to himself, and then when he walked to that place, he was about to lift the bluestone slab.

As soon as Sun Li came into contact with the bluestone slab, his face immediately changed, because this bluestone slab couldn't be lifted.

Three hundred catties, five hundred catties, and one thousand catties, the strength between Sun Li's hands continued to increase, but the bluestone slab seemed to grow on the ground, and it didn't move at all.

There's weirdness, there's big weirdness!

Sun Li was finally sure that this hall was really not the end of the vitality, but somewhere else.

In that case......

The next moment, Sun Li took a deep breath, held the Zhuxian Sword and slashed at the bluestone slab, and the strength of his whole body exploded instantly.

"Bang" stone chips flew wildly, and the bluestone slab was directly shattered, revealing a dark tunnel.

Then Sun Li jumped in without hesitation, and immediately as if he had triggered some mechanism, the fire oil contained in a special container in this dark passage was suddenly ignited, reflecting the entire dark passage.

Sun Li's eyes narrowed slightly, he was not afraid, but he was careful to be on guard, constantly moving forward and moving forward.

In the process of moving forward, looking at the formation patterns carved on the two walls, Sun Li was secretly frightened.

Sure enough, the hall was just a transit station, and there was a higher-level existence in this Spirit Gathering Array. In that case, I'm afraid that not only the vitality that I see in this area within a radius of dozens of miles will be emptied, but it is very likely that what I don't see will also be emptied of a larger area of local vitality.

So what is this called?

The Spirit Devouring Array can't be described, it can be called the Spirit Devouring Array.

Soul Eater!

What kind of person created this, and what did he want to do?

Sun Li speculated endlessly as he kept walking into the distance.

After walking more than a hundred feet, he suddenly saw a door in front of him. It was a door made of black iron, four zhang wide and three zhang high, weighing several thousand catties.

Sun Li pressed his hands up, and burst out with all his strength, but he couldn't move the iron gate in the slightest. So, after a rough estimate in my heart, I found that it was impossible to forcibly push open this door without the strength of five or six thousand catties, and this was still in the case of no other mechanism set up in this door.

Then, how can this be opened?" Sun Li frowned.

But then, Sun Li's eyes lit up slightly, and he saw that in an eye-seeking position on this door, there was a square grid engraved with "horizontal nine and vertical nine", divided into nine hundred and eighty small squares.

In this small square, about 30% of them are engraved with fixed numbers, such as "two", such as "Qi", and "Lu".

In the remaining squares, there are some number gears, and above the gears are nine numbers from "one" to "nine", which can be changed by turning the exposed numbers.

Obviously, it is the key to opening this iron door mechanism, similar to the existence of a combination lock.

And Sun Li just glanced at it, and his gaze became strange.

Because there is nothing else on this gate, it is Sudoku.

This is a modern logical game of number filling, in which the player must fill in each square with numbers, and each row, column, and square (i.e., the middle cell of three times three) must collect all the numbers from one to nine. Because the designer has already provided some numbers, such as those fixed on this black iron gate, there is often only one answer.

This kind of game requires logical thinking skills and has nothing to do with number crunching. Therefore, those who know how can crack it in a very short period of time, and those who can't meet it will not be able to crack it even if they want to break his head.

It's just that the appearance of something like "Sudoku" here feels a little weird.

Sun Li knows that Sudoku is actually somewhat similar to China's "nine-square grid" in modern history, and the "nine-square grid" is derived from the "Luoshu River Map" in ancient mythology.

Calculated in this way, it is not a big deal that this "Sudoku" appears here, but why is it still a little weird?

Also, who is so bored that he has such a mechanism?

Sun Li frowned and thought, but his hand was not idle, but began to turn the digital gears to crack this Sudoku mechanism.

"Click", the sound of the gears turning kept ringing, and when it reached the three hundred and twenty-first time, the whole door suddenly shook, and then opened with a bang.

Sun Li exhaled a breath of turbidity, and with a somewhat indescribable mood, he stepped into the black iron gate.

But after that, Sun Li's expression suddenly froze, and he saw that in the black iron gate, a copper gate suddenly appeared. In an instant, Sun Li had the urge to scold his mother.

Gritting his teeth, Sun Li stepped forward, and then pushed the copper door, and immediately calculated that without the strength of ten thousand catties, he would not want to forcibly open it.

It's no wonder, after all, copper is denser than iron, and it makes sense to sink a little.

But the density is reasonable, but the design is not reasonable.

Normal people, who would design two doors in a row?

With this depressed mood, Sun Li once again began to crack the "Sudoku" mechanism engraved on the bronze door.

This time, "Sudoku" is obviously much more difficult, it is "horizontal and vertical twelve", and the amount of calculation is more than double that of the previous one. So, this time, the sound of the gears turning lasted for more than 800 times before the copper gate opened.

Then Sun Li had a gloomy face and walked in again.

And after taking seven steps, Sun Li suddenly felt that he could now retract the sentence he had just said, the sentence "Normal people, who will design two doors in a row".

Because it turns out that this man not only designed two doors, but he also designed a third.

Well, there is another door at the back door of the copper door, a silver gate.

This silver gate, like the previous two doors, is four zhang wide and three zhang high, and the whole body is completely made of silver. It's really silvery, it's really fascinating.

And Sun Li looked at this silver gate, but he was stunned for more than a dozen breaths, and then couldn't help but think, is there a gold gate at the back door of this silver gate?

According to the strangeness of this designer, even if he made any agate gates and ivory gates, Sun Li would not feel strange.

At this moment, Sun Li really wanted to turn his head and walk back.

But after thinking about it for a while, I felt a little pity for the two Sudoku machines that I had just unraveled.

You've broken the two levels, and then give up, okay?

Not good!

Sun Li's heart quickly gave an answer, and the next moment, Sun Li, who had a gloomy face, walked straight to the front of the silver gate.

This time there was no need to push, Sun Li also knew that he would not be able to open the door of silver, after all, the density of silver was 1.7 times that of copper, and more than 1.9 times that of iron.

I can't even push open the previous two doors, so let's solve the problem honestly.

Well, solve the problem, solve the damn problem.
