In fact, even if the three-headed relief demon beast survived, it would not be a big deal, but judging by their reactions, they could still absorb energy non-stop.

If there is no upper limit on the amount of energy they can absorb, they will definitely fight stronger, and no matter how brave and good Zhan Wuji is, how long can they hold out under this loss?

At least as far as the current situation is concerned, the more they fight with these three relief demon beasts, the more they become stronger.

In this way, Duan Fei quickly made a decision in his heart, and while his body retreated, he also greeted Zhan Wuji.

"Senior Brother Zhan, retreat quickly, don't fight! These relief monsters are weird!!"

Zhan Wuji's combat experience itself was extremely rich, and after hearing Duan Fei's reminder, he quickly realized that these three relief demon beasts were indeed strange.

So Zhan Wuji raised his slashing knife horizontally, and came up with a spiral slash like picking up a chain ball, and after slightly forcing away the three-headed relief demon beast, he flew and jumped to Duan Fei's side, and the two of them retreated together, and at the same time extinguished the psionic flame used for lighting.

The three-headed relief demon beast was obviously unwilling to give up the delicious food in their mouths, and together they chased Duan Fei and Zhan Wuji, but the energy they absorbed was not enough, and it was not their best state at this time, and they had no advantage in speed, so they obviously couldn't catch up with Duan Fei and Zhan Wuji.

When Duan Fei and Zhan Wuji retreated to the middle of the main hall, although the surroundings were dark but they could already see, there was no trace of the three-headed relief beast, and listening carefully, the depths of the hall were silent, as if the three-headed relief beast did not exist at all.

According to Duan Fei's estimate, once these three relief beasts lose their target and are in a state where they have no energy to absorb, they are likely to return to the wall and become reliefs again.

That's the way this is right now, unless you can force your way through the three-headed relief monsters that can absorb energy and fight harder and harder, or you can pass through the main hall without alarming them, or you will only be trapped in the black hall.

Now Duan Fei can't use the Explosive Divine Power, relying on Zhan Wuji alone, the possibility of defeating these three relief demon beasts is almost non-existent, and the relief wall blocks the exit of the entire hall, if you want to pass through the main hall without alarming the relief demon beasts, how can it be possible?

After some testing just now, it can now be determined that the range of movement of the three-headed relief demon beast is that in an absolutely dark environment, they will not attack where there is still light.

To put it bluntly, this is just a level, not a real dead end, is it possible to get people who break into the main hall, trapped here and unable to move forward?

Duan Fei thought about it carefully, if the range of activities of the relief beasts was really limited to the area in absolute darkness, then finding a way to extend the light to the front of the wall would be equivalent to sealing the relief beasts inside the wall, so that they could no longer come out of the wall?

Of course, if you want to illuminate the dark area, you can't use Zhan Wuji's previous methods, if it's an external energy, it will definitely not work, it will only be absorbed by the relief demon beast, and only by using the mechanism in the black hall itself.

It's like cracking the stone door of the main hall, you have to find the right way.

So Duan Fei began to carefully observe the surrounding environment, and sure enough, he found a special feature that he had ignored before.

The walls on both sides of the main hall are made of thick rough stones, which have not been polished and have not been decorated much, and there is no special place on the surface.

However, after closer inspection, it can be found that some rough stones are not neatly stacked, and they protrude a little outward.

The number of these protruding rough stones is not large, and they are completely scattered on the wall, and they are not connected together at all, not to mention that it is difficult to find, and even if you see it at a glance, you will think that it is caused by rough workmanship.

But Duan Fei had the experience of cracking the gate mechanism, and now that he had made such a discovery, he suddenly had an association and began to carefully examine the position of these protruding rough stones on the wall.

Sure enough, as long as these protruding rough stones are viewed as a whole, they can also be regarded as a celestial star map!

However, compared with the celestial phase star map that Duan Fei memorized, the celestial phase star map composed of protruding rough stones obviously still has many mistakes and omissions, and there are obviously a lot of "stars"

The celestial phase star map on the wall is connected to the stone gate in the same vein, and there is almost a quarter of the content of the celestial phase star map, but there are not many errors and omissions, and it needs to be carefully compared before it can be found out slowly.

So Duan Fei calmed down, returned to the entrance of the main hall and began to carefully compare them one by one, as long as he found that there was an extra protruding rough stone, he pressed the protruding rough stone back, making it extremely neat with the wall.

Once Duan Fei corrected a mistake, he could feel that the light in the main hall would light up a point, which meant that Duan Fei's previous guess should be correct.

As Duan Fei walked towards the depths of the main hall again, the places he passed along the way this time were obviously much brighter, even if he came to an area that was in absolute darkness before, he could still have a light to shine around.

In this way, when Duan Fei and Zhan Wuxuan came to the wall blocking the exit again, although it was still very dark, they could also see the surrounding environment clearly, and the three-headed relief beast really returned to the wall, although it looked fierce, there was no sign of "living" at all.

Next, it was Duan Fei who pressed the last protruding piece of rough stone back, and then he heard a sound of "Kakaka", and the wall that originally sealed the way was separated from the middle like a portal, revealing a passage behind.

As long as you have the ability to crack the mechanism, then solving the problem is so simple, and after Zhan Wuji saw Duan Fei's performance, he had to admire it again.

Even if Duan Fei's explosive supernatural power was still in the cooldown period, the role he played was still extremely reusable, and it was obviously much stronger than Zhan Wuji's ability to break through.

This also made Zhan Wuji's heart more and more convinced, and he felt that working with Duan Fei was definitely the right choice, otherwise how could he go all the way so smoothly?

The passage behind the wall was not long, Duan Fei and Zhan Wuji walked out quickly, and then they felt that their eyes were bright, and at the exit of the main hall, there was an extremely vast square!
