The strange mountain field in front of him suddenly opened up, not only did it not have the shade of the trees before, but it also seemed a little abnormally empty.

There are no towering trees here, not even a single weed! Anyone can see how abnormal this must be!

Yu Dong didn't care about his own injuries in the slightest, and closed his eyes again to listen. This time, everyone understood that he was listening to the movement of the Lethe River, so as to determine whether they had reached the Second Heaven or not.

After a moment, Yudong nodded, signaling to everyone that they had once again 'rendezvous' with Lethe.

Speaking of this place in front of me, it is really very weird. Overall...... It's like a chessboard.

The huge bluestone slabs of two shades of color paved the way to continue up the mountain. The reason why it is said to be a piece is because the topography of this bluestone slab is square. In addition, the contrast between the dark and light colors is relatively large, and it looks like a black and white chessboard.

And between these bluestone slabs, there is really nothing. The grass is not even visible when it is clean. It is so obvious and abrupt that people can see at once that there is something wrong with these stone slabs.

Qin Zhen only looked at Yu Dong, and didn't immediately ask him what to do. Because even Da Luo Jin Xian had to give him some time to think about it before he knew what to do. Qin Zhen didn't want to be too embarrassed for Yudong.

However, according to Qin Zhen, if you want to say the safest way, it must be to fly over without your feet touching the ground. Just step on these stone slabs, and who knows what weird and terrible things will happen!

In the end, Lao Gu Xian couldn't stand this silence, and just as he was about to speak, he was stopped by Yu Dongyi raising his hand. Lao Gu froze there with his mouth open, and looked at Yu Dong squatting on the ground in a daze, using the knife in his hand as a pen, drawing something on the ground.

Lao Gu finally held back his patience and waited for Yu Dong to finish his work.

Qin Zhen leaned over a little at this time and looked at what Yu Dong had drawn on the ground. With directions and numbers, it looks like he's doing a hard math problem......

Qin Zhen couldn't help it, so he cautiously said: "Dong Shao, I haven't failed math since elementary school, and I can't understand your profound Olympiad. But I guessed a little...... Are you still researching Qimen Dunjia? ”

"Hmm." Yu Dong didn't raise his head, but still continued to count seriously.

Qin Zhen was angry, and he was very angry about the way he replied with this word.

And Lao Gu next to him muttered quietly at this time: "Da Zhen, you are content!" You talk and he gives you an 'um' back! I didn't even have the right to open my mouth. What's wrong? Where is Dong Shao doing math problems? ”

As soon as Gu Jie's words fell, Yu Dong squatted there and slowly opened his mouth: "If I guessed correctly, this Nine Heavens is a large array integrating Qimen Dunjia, Liuren Taiyi, and Witch Gu. If you want to break into this Nine Heavens, it is really difficult to go to the Blue Heavens. ”

"Don't say that, Dong Shao! We all believe in you! It doesn't matter what kind of A or B he is, when he comes to our major general, it's not easy to do it! How can there be a place where you can't get by! I can guarantee that you will be able to sweep through the thousands of armies in a while, and lead us straight to the Demon Lord's lair! Gu Jie encouraged and cheered hard in the back.

But Yu Dong didn't raise his head, and replied lightly: "I also dare to guarantee that I can't pass this Nine Heavens." ”

“……”

“……”

Qin Zhen suddenly had a feeling, otherwise he would have to break off on his own here. After the province went home, he had no shame to face the Jiangdong fathers! Yudong can't guarantee that he won't be able to pass the Nine Heavens, so what are they still bothering about here?

At this time, Yu Dong explained extremely indifferently: "Qimen Dunjia is the most profound technique of Taoism, and it is also the highest level of prediction in the Book of Changes, so it is known as the science of the emperor." After Xuanyuan Yellow Emperor got the Nine Heavens Xuannu to teach this method to break the truth, those who can apply this knowledge to the extreme are all military teachers and national teachers who govern the country and level the world. For example, Jiang Ziya, Fan Li, Zhang Liang, Zhuge Liang, Liu Bowen, etc., they mainly used the technique of Qimen Dunjia in military formation.

I don't know what kind of person that Hundred Demons Demon Lord is, who can understand both Taoism and witchcraft. But I know that I am not as good as the ancients, and I can't break the Nine Heavens.

You see, the chessboard in front of you now looks like a patchwork of black and white bluestones on the surface, but in fact, it combines elements such as nine stars and eight gates, three odds and six instruments. I don't know how the Demon Lord did it, but no matter how this formation is calculated or moved, there are only two results in the end.

The star of Tianying occupies the position of leaving the palace, and the main fire is scorching, which is related to the disaster of blood light. On the contrary, it is the Kan Palace, which is water, and the water becomes ice. To put it simply, no matter what color stone slab we go to, there are only two results in the end: one is to burn ourselves in flames, and the other is to freeze and freeze in extreme cold. ”

Although it is said...... They couldn't understand the Demon Lord's profound formation Qin Zhen, but they heard the cruel result clearly! Either way, it's like hell of torture.

But what Qin Zhen couldn't understand was that there was neither fire nor water here, how could they experience such a tragic pain?

Yu Dong finally shook his head helplessly and said, "Let's go, let's do our best." As he spoke, he stepped on the chessboard-like bluestone ground first.

Then all of them followed Yudong's footsteps and walked forward, and they were so careful that they didn't even dare to make a mistake with half a footprint! Strangely enough, they didn't feel either heat or cold! This...... Could it be that Yudong is thinking too much?

At this time, Lao Gu couldn't help but convulsively asked: "Eh, I said Dong Shao, what the hell does this mean?" What about the two heavens of ice and fire? Lao Tzu is still waiting, why doesn't it react at all? ”

Qin Zhen scolded Lao Gu angrily: "You/mother are sick, aren't you?" Still two heavens of ice and fire? You're blind, aren't you?! You have to hope for something evil, right?? I found you to be a thing! Let's go! It's best to have nothing to do all the way! ”

Qin Zhen was talking, and he heard Jiang Qi next to him say a soft 'ah'. It was definitely a feeling that he couldn't help but gasp. What could make Jiang Qi gasp, what had to happen?

Qin Zhen didn't care about arguing with Gu Jie anymore, and hurriedly looked ahead. I saw Yudong in front of him standing motionless, and about twenty meters away from Yudong, eight coffins suddenly appeared! The order in which the coffins were arranged was very special, and it was obviously part of the formation!

Qin Zhen and Gu Jie also didn't dare to move, for fear that if they took a small step, they would alarm the masters in the coffin.

These eight large coffins, four black and four red, I don't know if they symbolize the four ice and four fires. Qin Zhen couldn't even remember how far they walked in, let alone know that these coffins came out of nowhere? Or were they there in the first place?

What does this mean? If the four of them want to go on, they must pass through those coffins! This formation is too perverted, isn't it......

Gu Jie moved his wrist while looking at the coffins and said, "This can be regarded as finding the root of the disease." Eight times out of ten, the weirdness in this double heaven is from those coffins. Anyway, we are now jumping into the Yellow River with our eyes open--- cornered. Dong Shao, let's go! After saying that, he didn't act on his own immediately, but asked Yudong with his eyes.

And Yu Dong also nodded at this time and said: "These eight coffins should represent the eight gods of heaven, earth, Xuan, Bai, six, yin, snake, and Fu in Qimen Dunjia. If you can't break through these eight gods, you probably won't be able to get out of the double heaven. So...... Let's go. ”

They have all discussed, not scattered, not chaotic, this chessboard-like ground must have a saying. So at this moment, they all got together, and they went together wherever they said.

Sure enough, when they had taken four or five steps, there was a slight sound around them.

Several people stood still, listening carefully to the subtle movements. After listening to it for a while, Qin Zhen felt a little uncomfortable. Because the voice ...... It's like the sound of fingernails scratching something.

Although the movement is not loud, it is very harsh! It felt like a pair of spiky ghost claws scratching at your eardrum! It was very uncomfortable for those who listened!

However, the most uncomfortable thing was not the sound of the nails scratching things, but the sound that seemed to come from one of the coffins in front of them!

This time, Qin Zhen and Gu Jie were a little confused! I have listened to a lot of ghost stories since I was a child, and my liver tremors when I see the coffin. What's more, in this deep mountain range, there was a sound of fingernails scratching the lid of the coffin from the coffin that suddenly appeared! This gave them goosebumps!

Don't look at Jiang Qi's reaction as much as they did, but that resolute face also looked very dignified, and it was not difficult to see his nervousness with a frowning brow. Obviously, this special officer may have seen a rain of bullets, but he has not seen such a scene.

Of course, among them, Yudong is the most calm. He just stood there, unfazed, unmoved, quietly looking at the big vermilion coffin that was making a screeching sound.

It's like comparing perseverance with a coffin. In the end, it was the coffin that couldn't hold up first......

Just listen to the 'click'! The coffin lid...... I actually opened it myself.
