Chapter 598 Carving out a path

Although Wen Chi was not optimistic about Qin Shu and was very puzzled about her carrying the "Complete Collection of Formation Techniques" with her, he thought that since he was trapped here, he would have nothing to do, so he let her go.

However, among the three of them, Qin Shu was reading, Cheng Yan was running, and Chi Yu was practicing swordsmanship, so he seemed to be doing nothing.

Wen Chi could not sit still, "We are all trapped, why don't you take a break?"

Cheng Yan and Chi Yu ignored him, only Qin Shu slowly raised her head and looked at him.

"Brother, don't talk if you have nothing to do, your train of thought is interrupted."

Wen Chi: "..."

After Qin Shu said this, he leaned over again, "Can you really understand it?"

Qin Shu nodded slightly and hummed, "Of course, I have also entered the door."

Wen Chi: "?"

When did this girl enter the door of formation? Why have I never heard her talk about it?

But seeing Qin Shu taking out paper and pen to write and draw seriously, he didn't want to disturb her.

Qin Shu was studying the formation seriously. There were quite a few extremely cold formations in the "Compendium of Formations", but it was a bit troublesome to find which one they were trapped in now.

She just checked and eliminated them one by one, and suddenly a fragrance came from the tip of her nose, which was particularly rare in this extremely cold world.

Qin Shu raised her head and looked in the direction of the fragrance.

She was stunned when she saw it.

She saw her second brother took out a small stove and was boiling tea on it.

Even if she didn't recognize what kind of tea he was boiling, she knew it was a good thing just by the smell.

Qin Shu came over with her book in her arms, and Wen Chi asked, "Would you like a cup?"

Qin Shu nodded honestly, and a sound of water sounded in her ears. The next moment, a cup of hot tea was handed to her.

Qin Shu looked at the steam above the tea, and suddenly showed a thoughtful look.

Her eyes slowly moved down and fell on the bottom of the water stove.

Wen Chi saw that she wanted tea but didn't reach out to take it, so he asked curiously, "What's wrong?"

Qin Shu frowned slightly, "Brother, your fire can't melt this ice?"

The melting point of ice is zero degrees, even children know that.

The fire in this stove is also generated by Wen Chi's spiritual energy, how could there be no signs of melting at all?

Wen Chi hadn't noticed these things before, and only lowered his head to check when Qin Shu mentioned it.

"The temperature here is too low, maybe it has some effect?" Wen Chi guessed.

Qin Shu shook her head and said confidently: "Even if the low temperature has an effect, there will definitely be signs of melting on the contact surface."

Wen Chi thought about it, and called Chiyu, who was concentrating on practicing sword, "Junior Sister Chiyu!"

Chiyu frowned and turned back, and heard Wen Chi say: "Try to roast these ice with your fire."

Chiyu put away the sword and walked over.

Wen Chi repeated again, "My fire can't melt these ices. Your fire is hotter. Try it."

Chiyu raised his hand and made a gesture. He struck out with his palm, and a ball of fire hit the ice surface.

With the continuous input of spiritual energy, the flame lasted for nearly a quarter of an hour.

However, as the flame dissipated, the ice surface was still very smooth, without any water stains.

The three looked at each other, and a thought suddenly popped up in Qin Shu's mind.

Are they really on the ice now?

This thought just came up and gradually took root in her mind.

In order to verify her conjecture, she turned her wrist, took out a sword, and stabbed into the iceberg with all her strength.

With the addition of the sword and her strength, she really poked off a piece.

She put the debris in the palm of her hand, and a flame also came out.

Not only did it not melt, but the cold feeling gradually dissipated.

Qin Shu put the transparent debris in front of her eyes, and looked at the enlarged handsome face of Senior Brother Wen Chi through the debris.

She suddenly chuckled, Wen Chi didn't understand why, and then heard Qin Shu utter two words: "Crystal."

Wen Chi was stunned, and Chiyu frowned slightly, "You mean, these are not ice, but crystals?"

Qin Shu nodded, "No mistake, you will know when you see it yourself."

She handed over the debris in her hand, and Chiyu understood the moment she took it, "It is indeed crystal."

But then she was even more confused. Is there a trick here? Can it hide from her true eyes?

"But, since it is not ice, how is the extreme cold formation generated?" Cheng Yan came over and asked.

The four people looked at each other and saw the answer in each other's eyes.

"Extremely cold ice soul." The four people blurted out at the same time.

It seems that the extremely cold ice soul is indeed here, but how can they find it?

Being trapped in the crystal formation is not a good thing. After all, ice is afraid of fire, so what is crystal afraid of?

Qin Shu touched her chin and fell into deep thought.

It was like watching a movie in her mind, and all the array formulas she had just seen appeared in her mind.

Crystal and ice are also transparent, and they can use the property of light transmission and the overlap of light and shadow to create a three-dimensional array. If they can't find the angle of light and shadow overlap, they won't know where the array is hidden, let alone break it.

Ice can provide coldness from all directions, but crystal is different. It relies on the extremely cold ice spirit to provide energy.

In other words, in addition to this overlapping light and shadow, there must be a point to store the extremely cold ice spirit, which is equivalent to the role of a battery in later generations.

But logically speaking, the crystal is so transparent that even a mosquito can't escape their eyes, let alone an extremely cold ice soul.

Or did they use light and shadow to hide the whereabouts of the extremely cold ice soul?

Or...

Qin Shu's sight slowly passed over the ice, or...hidden in the white shadows?

This is very likely. Qin Shu used the ten thousand year ice marrow for the white shadows' eyes before, why can't she use the extremely cold ice soul this time?

Qin Shu was silent, and no one else disturbed her.

Seeing that she finally opened her eyes, Wen Chi asked, "What did you think of?"

Qin Shu nodded, stood up, raised her hands and touched the crystal walls around her to feel it.

Logically speaking, the closer to the extremely cold ice soul, the lowest temperature should be, and the test at this time is the perception.

She sensed the approximate area she calculated for a long time, and finally pointed in the direction of one of the white shadows and said, "Dig there!"

The three of them looked at her, "Are you sure?"

Qin Shu nodded, "Since we can't get out anyway, we might as well dig a way out by ourselves."

Her strange argument actually magically convinced Wen Chi, and he took out a spiritual pickaxe for digging herbs and said, "I'll go first!"

This crystal wall is very hard, but it is not completely impossible to dig. Once the spiritual pickaxe hit it, beautiful crystal fragments flew everywhere.
