Lin Zhuo thought slightly in his heart, and after half a ring, his expression moved, as if he had thought of something, and walked a few steps closer, came to the iron barrage door, and looked carefully at the four notches.

As he watched, Lin Zhuo soon found that under the four notches, four skeletons were depicted, and these four skeletons were half-kneeling on the ground, holding their hands high, and holding them up...... It is these four notches.

Lin Zhuo had a very familiar feeling, and when he looked closely, these four skeletons were the same as the four skeletons by the lake...... It's obviously exactly the same, and even the action of holding it up is the same!

The only difference is that the four skeletons in front of me are not holding up weapons, but four notches.

But Lin Zhuo instantly understood, to be precise, these four skeletons were not holding up the notch, but the weapon in the notch, but the weapon had disappeared, so it seemed that these four skeletons were holding up the four notches.

Actually, no, as for the four weapons in the four slots, they are in Lin Zhuo's backpack at the moment!

"Could it be that those four weapons are the keys to open this iron bar?" Lin Zhuo looked at the four notches, thoughtful, and soon had an answer in his heart, but he didn't dare to try it easily, after all, the four epic weapons in his backpack were currently very valuable, and their value was indescribable.

Even if these four weapons are really the keys that can open the iron barrage door, Lin Zhuo is also a little hesitant, because he doesn't know that after putting the four weapons into the notch, once the iron barn door is opened, the four weapons will disappear, and if they will disappear, it means that he is equivalent to using four epic weapons to replace the black and white egg inside.

And that egg, Lin Zhuo didn't know the specifics, if it was just an epic egg, then he would lose a lot, using four epic weapons, but only in exchange for one epic egg.

Lin Zhuo was a little hesitant and reluctant to try, because his character was like this, unless it was some special circumstances, he preferred to be stable and unwilling to gamble without knowing it.

This can be seen from the fact that he came to the world of the dead and always followed behind everyone, he would rather not take advantage of the first, but also choose to follow behind everyone safely, and it is precisely because of this safety, with his own strength, that he has come all the way here without death.

However, Badao is the opposite of Lin Zhuo, in addition to being confident in his own strength, he prefers to take advantage of some small advantages, so he always follows behind the hungry ghost, wanting to take advantage of everything.

Even inside the cave, after the stone door opened, he could have left unharmed, but he did not leave, but planned to fight for the key.

At this moment, Lin Zhuo pondered for a moment, and decisively chose to retreat, no longer thinking about the pet egg, after all, his best choice at the moment was to keep the four epic weapons and give up an unclear egg.

But the moment he retreated, the dagger he held in his hand suddenly glowed with a black glow, and it made a buzzing sound, and this buzzing sound sounded like a cheerful and pleasant sound.

As the buzzing sound sounded, Lin Zhuo found that the dagger in his hand was trembling violently, as if he had spirituality, and wanted to break free from his hand and fly out.

Soon, the dagger trembled more and more, and in the end, it was almost struggling, as if it wanted to break free from Lin Zhuo's shackles, which made Lin Zhuo's eyes freeze, without the slightest hesitation, and directly moved his mind, intending to put the dagger in his backpack.

"Ding~!"

The system prompts: "Failed to put item into backpack. ”

......

The system prompt sounded, Lin Zhuo's heart was shocked, and at the same time, the dagger in his hand directly broke free from his hand at this moment, and with a whoosh, it flew out in an instant, heading straight for one of the notches.

In the blink of an eye, after the dagger flew out, it automatically fell into the notch, and the notch lit up a glimmer of light at the moment when the dagger fell, and at the same time, the dagger seemed to merge with the notch and became one with each other.

Seeing this scene, Lin Zhuo frowned slightly, but he didn't feel much shock in his heart, after all, when the dagger was struggling before, he felt that one of the notches came out with a desire for the dagger.

And the dagger, as if it had been summoned, seemed to have woken up, and with spirituality, it would violently break free from Lin Zhuo's hand, and go straight to the notch desperately.

And now, the notch and the dagger have fused together and become one, which means that Lin Zhuo has been unable to retrieve the dagger and has completely lost the dagger.

"Are you trying to force me to take out the other three weapons?" Lin Zhuo squinted slightly, looking at the remaining three notches.

If the four weapons were still there before, then Lin Zhuo would not have considered opening the iron barrage door, but now that one of these four slots had been opened, he had a trace of impulse in his heart at this moment, wanting to put the remaining three weapons into the slots as well.

Even at this moment, as the dagger was integrated into the notch, Lin Zhuo clearly noticed that the position where the iron bar door was locked had been loosened a little, making Lin Zhuo very sure that as long as he took out the three weapons and put them in the notch, he would definitely open the iron barrage door.

In this way, it can be said that these four weapons are actually four keys...... The key to unlock this barred door! Lin Zhuo thought for a while, and gradually had an answer in his heart.

"What a big deal, I actually used four epic weapons as keys to lock an egg!" Lin Zhuo's eyes flashed slightly, his gaze looked through the iron bar, looking at the black and white eggs inside, after half a sound, he no longer hesitated, and directly moved his mind and took out a big sword.

As soon as this big sword was taken out, immediately the remaining three notches, one of them, instantly emitted a longing thought, and the big sword in Lin Zhuo's hand also trembled violently, wanting to break free from Lin Zhuo's hand and fly towards the notch.

Lin Zhuo directly let go of his hand, and soon the big sword automatically flew up and went straight to the notch, the speed was so fast that it fell into the notch in the blink of an eye, and merged with the notch.

At this moment, as the big sword fell into the notch, the locked position of the iron bar door loosened a little again.

Lin Zhuo's mind moved, and he took out a bow and arrow, and as he let go of his hand, the bow and arrow automatically floated up, and with a whoosh, it went straight to one of the notches, and instantly fell into it.

At this point, three of the four slots are equipped, and only the last one remains.

"I hope this egg won't let me down!" Lin Zhuo's eyes showed essence, and with a movement of his mind, he took out the last weapon, which was a magic staff.

As Lin Zhuo let go of his hand, this staff made a buzzing and cheerful sound, and flew away in an instant, heading straight for the last notch.

In the blink of an eye, it fell into the last notch, and at the same time, the four notches lit up in an instant, and the entire secret room trembled violently at this moment.
