Godly Student

Everyone chatted softly at the side, but this time everyone's topic is no longer the formation, but they are looking forward to what treasures you can find below after the formation is activated, or to see what the sealed thing is. what is it.

Cheng Yu, on the other hand, sat alone in front of the formation and polished the spirit crystal. He needed to constantly modify the spirit crystal according to the appearance of the empty slot. If it is polished properly, he will show a satisfied smile, and if it is not polished properly, he will frown.

Seeing that every time a problem arises, the women need Cheng Yu to solve it. Seeing Cheng Yu's concentration, they will always feel sorry for Cheng Yu. But there is no way, the greater the ability, the greater the responsibility, this has always been the pride in their hearts.

Whether it is checking the formation or polishing the spirit crystal, it is a meticulous job, and there must be no sloppy work, or it is very likely that all previous efforts will be wasted.

Sweat ran down Cheng Yu's cheeks, and several women wiped the sweat carefully for him, with distressed expressions on their faces.

"Don't be so anxious, we can wait slowly!" Yao Na said gently as she wiped off Cheng Yu's sweat.

"It's okay, I can't trouble myself with such a trivial matter!" Cheng Yu smiled at Yao Na, and continued to polish the spirit crystal seriously.

After about three hours, Cheng Yu created a suitable spirit crystal according to the shape of the empty slot.

"I'm not sure if this spirit crystal will work. I've worked hard to polish it according to the shape of this empty slot. I hope it will succeed once!" Cheng Yu took the built spirit crystal and prepared to put it into the empty slot. , I was also very nervous.

The others also watched Cheng Yu's movements nervously, hoping that the Spirit Crystal, which took so long to build, could successfully activate the formation.

Click!

When Cheng Yu pressed down the spirit crystal, everyone could clearly hear the sound of the spirit crystal getting stuck in the slot.

"It should be fine this time!" Everyone felt that their hearts were about to jump into their throats.

However, what was disappointing was that everyone waited for a while but did not see any other reactions.

"Failed?" Everyone said in frustration.

Even Cheng Yu showed extreme disappointment at this time. He spent so much effort to polish such a spirit crystal, but he didn't expect that the final result would still not fail.

"It does appear to have failed,

It's been so long and there is no response yet! "Xinhe shook his head and said helplessly.

"What should we do now? Is this a problem with the spirit crystal or something else? Could it be that the exit is really down below, and those guys took away the two spirit crystals when they went out?" Xinhai guessed.

"Master, I think there is still a problem with your spirit crystal!" At this time, the black devil stood up and said.

"How to say?" Cheng Yu looked at the other party and said.

"Although this spirit crystal of yours, master, was polished according to this empty slot, the structure inside this empty slot is not ordinary, and it can be said to be somewhat complicated. It is definitely easy to make mistakes if you polish it like this. I think you should It will be more reliable to take out this piece of spirit crystal, and then copy it according to this piece of spirit crystal!" Hei Mo said, pointing to the spirit crystal that was stuck in the slot.

"That's right, Junior Brother Yu, you might as well take this piece of spirit crystal and polish it, it will definitely work!" Xinhai patted his thigh and said.

In the absence of any comparison, it is bound to be much more error-prone to just polish it according to the shape of the groove.

"But if this spirit crystal is removed, it will be useless. If this slot is different from the one here, wouldn't even this spirit crystal be destroyed?" Cheng Yu Said with some hesitation.

"If we can create the correct spirit crystal based on this spirit crystal, then even if this spirit crystal has expired, we can copy it again. At most, it's just a waste of time and a spirit crystal!" Black Demon said.

"Okay, then I'll take this spirit crystal off and have a look, I hope the two slots are the same!" Cheng Yu thought about it, anyway, even if this piece is taken off, even if it fails, he can do it anyway. According to this piece of spirit crystal, copy a piece that is exactly the same.

In case it is not used here, it turns out that this slot can still be used after all.

Snapped!

Cheng Yu took off the spirit crystal at once, and obviously felt that the color of the spirit crystal turned white after it was taken off, and it no longer had the unique luster of the spirit crystal, which shows that the spirit crystal has indeed failed .

Then Cheng Yu took off the one he had polished before, and compared the two empty slots carefully, and a look of surprise appeared on his face.

"Great, these two empty slots are indeed the same, now I should just copy two pieces of this spirit crystal!" Cheng Yu said happily after seeing the result.

"I'm scared to death. I'm really afraid that the two empty slots are different, or I'd have to waste a lot of time!" Seeing this result, everyone finally smiled amidst the tension and distress.

"Now that we have a template, we need to polish a few spirit crystals to get them out. If there is no exit below, even if we get to the bottom, we still need to use spirit crystals to open the formation leading to the top." Cheng Yu thought for a while Said.

"Well, if that's the case, let's help you polish a few spirit crystals together, it will be faster, anyway, there is already a template." Xinhe said.

"Young master, we can polish one for you!" Black Demon and White Demon also said.

"Well, it should be almost enough for the four of us to polish four spirit crystals. We use two here and keep two for later use!" Cheng Yu nodded and said.

So, the four of them started to compare and imitate the original spirit crystal constantly. Cheng Yu compared this original version with the spirit crystal he had polished before, and indeed found that the spirit crystal he had polished only against the empty slot lacked a lot of things.

Now that there is a template, the speed of four people building spirit crystals is much faster than Cheng Yu's own groping, at least double the speed, but even so, it still took more than an hour for four people to polish spirit crystals.

"It's finally finished, there should be no problem this time!" After all four people finished, seeing the four spirit crystals that were exactly the same as the template, everyone's confidence was greatly increased. I believe that this time they will be able to successfully activate this formation. .

Cheng Yu first put one of the spirit crystals back into the slot where the spirit crystals were originally placed. There was no response to this piece of spirit crystals except for the sound of being stuck in the slot, because it was obviously opened. For a bottom-up formation, there must be an empty slot below the formation.

And when Cheng Yu was about to insert another piece of spirit crystal into the slot to open the formation leading to the bottom, everyone became nervous again, praying in their hearts, they had already spent too much time and energy here, Can't fail anymore, otherwise they really don't know what to do!

Snapped!

Cheng Yu inserted the spirit crystal into the empty slot again!
