I can't remember where I've seen this key, which makes Chu Tianming crazy.

At this moment, the gluttony on the side suddenly stared at the key for a while.

"What, you've seen it?" Chu Tianming was puzzled, if he had seen it, then he should have really seen it, but why couldn't he remember it?

"It's familiar." Tao Tao nodded, "It seems that you have a key that looks similar, master." ”

"I have one?" Chu Tianming's mind flashed with inspiration, and he suddenly laughed out loud on his forehead, "I remember, I have one, the one that I just met you that can open the treasure chest." ”

Chu Tianming rummaged for a while, and finally found the white jade key in a corner of his consciousness space.

The same white jade color, the size is exactly the same, the only difference is the carving on the key handle.

Chu Tianming's original one was carved with a sheep's head, but now the one in his hand is carved with a tiger head.

One sheep and one tiger, this difference is huge.

Holding these two keys, Chu Tianming looked up and down, left and right, and couldn't see anything magical about these two keys.

"What the hell do these two keys do?" Chu Tianming was puzzled, "The key should be used to open the lock, so can it be considered that these two keys are used to open the two locks of a certain place or an object?" ”

Thinking of the lock, Chu Tianming thought of the treasure chests he had opened.

"Let's see if we can open that crystal chest."

Chu Tianming took out his only crystal treasure chest, and then pointed the sheep's head key at the keyhole and inserted it.

"Huh?" I twisted it a few times, but the key didn't move, "Can't you?" ”

Pulled out the sheep's head key. Chu Tianming was somewhat disappointed.

"It seems that if this is not used to open these treasure chests, at least not to open crystal treasure chests." Chu Tianming shook his head, and then tried the tiger head key, but he was also unable to open this crystal treasure chest.

Chu Tianming, who was completely dead, withdrew the crystal treasure chest into his consciousness space, and then looked at the two keys in his hand and pondered.

A key. It must have been able to open a lock corresponding to it, but Chu Tianming now had the key, but he couldn't find where the lock was, which made him very annoyed.

"The two platinum treasure chests that I finally got were scrapped at once. It's unlucky! Chu Tianming shook his head and sighed, "Forget it, even if I'm unlucky!" ”

Reluctantly withdrew the two white jade keys into the consciousness space, vaguely, Chu Tianming always felt that these two keys would bring him some surprises, but he didn't know when this surprise would come to him.

The first platinum treasure chest was scrapped, and a white jade key was issued that I didn't know what to do for it for the time being.

Second. Chu Tianming picked up the second one, the more the last platinum treasure chest left.

Picking up the key, he clicked open the lid of the chest.

This time, Chu Tianming's mood was even more nervous, he was really afraid that there would be another white jade key with a dragon head and a dog's head or something. If it really appeared, Chu Tianming would be angry to death if he thought about it.

The probe looked inside the treasure chest, and Chu Tianming was very slow, looking into it little by little.

"No white!" Chu Tianming's heart was overjoyed, and then his eyes widened, and a strange look suddenly appeared on his face.

"What is this?"

With a puzzled face, he picked up the object in the treasure chest.

In Chu Tianming's hands. It is a strange crystal the size of a fist with countless facets on its surface.

"Diamonds?" Chu Tianming squeezed hard, "No." Diamonds are not that hard. ”…,

If it was a diamond, he would have turned it into powder with a slight pinch, and the crystal was now undamaged by his hard grip, which proved that it was not a diamond.

But what if it turns out it's not a diamond? Chu Tianming still didn't know what it was for.

At this time, he couldn't even help himself with the detection technique, just like he didn't know anything about the two white jade keys, under the detection technique. They're all a bunch of question marks.

"This detection technique is getting less and less powerful!" Chu Tianming complained a little in his heart.

Actually, it's not that the detection technique is not powerful. It's that the thing Chu Tianming encountered is really special, and it is beyond the scope of detection techniques, how can you call it powerful!

The detection technique couldn't detect it, and Chu Tianming couldn't recognize it himself, thinking about it, Chu Tianming still threw the problem to the deceased system.

Opening the question panel, Chu Tianming meditated in his heart that he wanted to know the origin and purpose of the thing in his hand.

Soon, the system gave itself a hint.

"This question costs 1,000 XP, does the system need to answer it?"

Chu Tianming thought about it, this thousand experience points is a lot! But this time, he mainly wanted to open the treasure chest to open something useful, and now it's a good thing, he actually opened two unknown things, if he didn't know the purpose of one of them, wouldn't he be busy in vain!

"A thousand is a thousand." Chu Tianming was ruthless and directly agreed to the system, allowing him to deduct a thousand experience points from himself.

As soon as the experience points were deducted, the system immediately gave a satisfactory answer to Chu Tianming.

"Array seal, a multi-functional immortal magic weapon that can absorb formation storage formations, the quality of each formation seal, as long as there are many facets on its surface, it can be seen at a glance, the more facets, it means that it can absorb and store more formations, each facet can store a formation, regardless of the size and level of this formation, a facet can only store one, the formation stored in the formation seal, you don't need to consume any energy, you don't need to arrange it in the original space, you just need to project it into the original space, you can use it."

The system gave the answer in great detail, and at the back of this introduction, there was also some information about how to use the array seal, how to make the array seal recognize the master, and how to use the formation in the array seal, so detailed that even a little little unimportant function was introduced in detail, and Chu Tianming was relieved to see it.

"Yes! It's worth the 1,000 XP points! Chu Tianming said with a smile.

Looking at the array seal in his hand, Chu Tianming carefully counted the cuts on it, and immediately gasped.

The formation seal in his hand actually had a total of 9,999 facets, each of which was extremely small, but this one facet meant that it could store a formation, and these 9,999 facets didn't mean that it could store 9,999 formations?
