There were also some numbers next to each set of numbers, and Qing Shu quickly rotated with the ten fingers of his hands, and he said a string of numbers in his mouth.

Yana Er quickly pressed on those numbers according to the numbers in Qingshu's mouth, and each number glowed with a dazzling light.

When all the answers were counted by Qingshu, a layer of dazzling white light had already appeared on the cliff wall.

The number next to each set of calculated numbers had been answered by Yana'er, and as the dazzling white light from the cliff wall flashed out, the cliff began to emit a roaring vibration.

"Boom",

I saw the sound of the mechanism activating from the cliff, and the sound shook the cliff and trembled.

The suspense had not been completely eroded by the barren air, and the mechanism in the cliff wall was clearly still intact.

"Boom ......",

With a loud bang, a stone door appeared on the cliff wall, and the stone door slowly opened.

"Yes, your arithmetic skills are really good." Dongfang Bai had to admire Qingshu's arithmetic level, he patted Qingshu on the shoulder and said.

"Of course, don't look at who I am, how do you think Mr. Shushan's last disciple is so good!"

Qingshu said proudly.

The Jiang sisters also rolled their eyes, revealing shocked eyes.

They didn't expect this little fat man in Tsing Yi to be so powerful.

Although Qingshu doesn't have any cultivation, he can't even fly in the sky, but it's not useless.

"Angel Yanael, please first." Ding Xiaoyi said to the bright and wise angel.

Yanar was not polite, and she was the first to enter the slowly opening stone door.

Then there was Qingshu, Dongfang Bai let the Jiang sisters follow behind Qingshu, and he was the last to enter the stone gate.

As soon as they entered the stone gate, they seemed to appear in a vast starry sky.

All around them were also a sparkle of stars.

There was also a vast starry sky under their feet, and it was as if they were stepping into the infinite stars.

"This is a glass piece, and this space is just some images of the starry sky preserved in this glass piece." Yanael looked around as she explained to the crowd.

"Yes, this is just an image preserved in the glass tablet, we seem to be in this starry sky, but in fact we are still in this cliff. I don't know who is so big that this cliff wall is covered with this glass piece and projects such a fantastic starry sky scene. ”

Ding Xiaoyi came to a star that shone brightly, he reached out and knocked on the star, and sure enough, there was a crisp tapping sound.

"Wow, it's beautiful, it's just like being there." The Jiang sisters couldn't help but sigh.

"Angel Yanael, have you ever been inside?" Qingshu asked the angel of light curiously.

"Well, I came in once, but there were a few levels ahead that stumped me, so I had to come to you for help!"

Yanael didn't hide herself, but generously admitted it.

Hearing Yana'er admit that she had already entered once, everyone became interested in the level ahead.

"What's the previous level, or arithmetic?" Aoyama asked curiously to the angel of light.

"It's not necessarily arithmetic, and there are some tricky puzzles, anyway, you can see it." Yana Er shook her head at Qingshu and replied.

"What kind of puzzle, isn't it a big deal to break it with a sword?" Dongfang Bai is a barbarian, he said disapprovingly.

"We can't destroy it with violence, although we are in the glass array, if we violently destroy this glass array, it will trigger the mechanism here, and this mechanism is an organ that contains space and time, and we will fall into endless spatial cracks."

Yana'er explained to Dongfang Bai.

"Is it so complicated, where is this cliff connected, it can't be a city of oblivion, right?"

After hearing Yana'er's explanation, Dongfang Bai's face couldn't help but change.

If they fall into the spatial rift, even if they cultivate to the sky, they will be instantly cut into nothingness by that spatial rift.

"No, there's something weird about this place, and we don't know where to go, but once we've solved all the puzzles, we'll know."

Yana'er lifted her thick glasses, and then explained to Dongfang Bai again.

"Is this starry sky real?" The Jiang sisters looked curiously at the starry sky with the bright light, and asked curiously.

"Who knows, this place is very evil anyway." Dongfang Bai began to become cautious.

Wouldn't it be dangerous if this place was as Yana El said, and the violent destruction would trigger the mechanism to send them into the rift in that space.

Then, they appeared at a huge glass screen, only to see a number problem appear on the glass screen.

It is a blank nine-square grid, just fill in the number on the blank nine-square grid.

"This is a nine-square grid algorithm, and the sum of each row and each hypotenuse is the same."

Qingshu looked at the blank nine-square grid, and he couldn't help muttering to himself.

"How do you calculate this, what kind of number game is playing, it's boring!" Dongfang Bai muttered impatiently.

"Angel Yanael, are you blocked here?" Qingshu asked Yana'er curiously.

"Yes, these nine-square grids have to fill in different numbers, and Yana Er can't calculate them, so she doesn't dare to act rashly."

Yana'er's face showed a bitter look, and she replied to Qingshu.

"Alas, isn't it just Jiugongge, I thought there was something great." Qingshu said disapprovingly.

After speaking, he filled in the numbers in the nine-square grid.

As he finished writing the last number, the vast starry sky around him suddenly exploded, and everyone only felt that their eyes were filled with the dazzling light.

"Whoa",

The glass screen suddenly shattered open, and then turned into countless rays of light and scattered in all directions.

A stone staircase appeared in everyone's sight, and the stone staircase was already broken, and the stone staircase extended forward.

Everyone hurriedly walked up the stone steps, and on both sides of the stone steps were the abyss, and the abyss was bottomless, like an ancient abyss beast.

The crowd walked slowly along the stone steps.

There was no sound, no light, just the stone steps.

The stone steps were like a single-plank bridge to heaven, and they were walking deeper into the cliff.

"What the hell is this secret realm, and why is it so well preserved. Moreover, our vitality and cultivation do not seem to have been eroded, and there is no sign of passing away. ”

Dongfang Bai reminded everyone, but Ding Xiaoyi was secretly thinking, this site was very weird, and he didn't feel any power of law at all.

It's like being in the mysterious realm of the sea, except that the ruins are smaller and more weird.

This and the secret realm of annihilation outside are completely two worlds, and there is no aura of annihilation here, and there is no sign of being eroded by that aura of annihilation.

There are also images of the vast starry sky preserved on the glass screen, just like some of the images he saw in the mysterious realm of the sea.

Could it be that this site has any connection with the sea mystery realm, Ding Xiaoyi couldn't help but secretly think in his heart.

After hearing Dongfang Bai's reminder, Ding Xiaoyi also found that his vitality and cultivation really did not seem to have passed, which made him even more confused.

Ahead, there was another arithmetic problem in the stone steps, but the arithmetic problem was engraved on a glass screen next to the stone steps.

"Hundred rabbits walked into the camp, several men and women fought each other, and it was difficult for one person to take all the ,......", Qingshu couldn't help but read out the title when he saw it.

"Four and three people have to stop, come and go, make trouble, everyone has to go home ......", Dongfang Bai also came up curiously and said.

"It's a question of how many people are counted, Angel Yanael, can you figure it out?" A confident smile appeared on Qingshu's face, and he said to Yana'er.

"I won't count, this question is too biased!" Yanael shook her head and said.

Hearing Yana'er's answer, Qingshu was not polite, he stood beside the glass screen and began to calculate.

A quarter of an hour later, Qingshu filled in the calculated numbers on the glass screen.

When Qingshu filled in the number on the glass screen, the stone steps in front of them suddenly shone brightly, and a road to heaven appeared in front of them.
